+# /evolve — Goal-Driven Compounding Loop
+
+> **Cross-vendor analog:** Anthropic Managed Agents Outcomes (May 2026). Both close the loop "agent runs → grader scores against a rubric → agent retries"; AgentOps does it locally against any model.
+
+> Measure what's wrong. Fix the worst thing. Measure again. Compound.
+
+**The loop runs as this skill (skills-are-the-runtime).** `evolve` selects work
+and invokes complete `/rpi --auto` cycles — that *is* the loop. `evolve` (and
+`ao rpi loop --supervisor`) are terminal-native **wrapper commands** for humans or
+non-skill runtimes, not the default expression of the loop; they reuse the same v2
+RPI loop engine. (The substrate dispatches the whole `evolve` skill loop as one
+unit; it never drives the loop's insides. The `evolve`/`ao rpi` CLI wrappers are
+being retired — ag-iowf.)
+
+**Operator cadence:** post-mortem finished work, analyze the current repo state,
+select or create the next highest-value work item, let `rpi` handle research,
+planning, pre-mortem, implementation, and validation, then harvest follow-ups
+and repeat until a kill switch, max-cycle cap, regression breaker, or real
+dormancy stops the run.
+
+Always-on autonomous loop over `rpi`. Work selection order:
+1. **Harvested `.agents/rpi/next-work.jsonl` work** (freshest concrete follow-up)
+2. **Open ready beads work** (`bd ready`)
+3. **Failing goals and directive gaps** (`ao goals measure`)
+4. **Testing improvements** (missing/thin coverage, missing regression tests)
+5. **Validation tightening and bug-hunt passes** (gates, audits, bug sweeps)
+6. **Complexity / TODO / FIXME / drift / dead code / stale docs / stale research mining**
+7. **Concrete feature suggestions** derived from repo purpose when no sharper work exists
+
+**Work generators** that feed the selection ladder (auto-invoked, skip with `--no-lifecycle`):
+- `Skill(skill="test", args="coverage")` → files with <40% coverage become queue items (Step 3.4)
+- `Skill(skill="refactor", args="--sweep all --dry-run")` → functions with CC > 20 become queue items (Step 3.6)
+- `Skill(skill="deps", args="audit")` → deps with CVSS >= 7.0 or 2+ major versions behind become queue items (Step 3.5)
+- `Skill(skill="perf", args="profile --quick")` → perf findings become queue items when hot paths detected (Step 3.5)
+
+**Dormancy is last resort.** Empty current queues mean "run the generator layers", not "stop". Only go dormant after the queue layers and generator layers come up empty across multiple consecutive passes.
+
+**Live skill edit immune system:** if an evolve cycle edits
+`skills/<slug>/SKILL.md`, run
+`ao skills edit seal --skill <slug> --actor "${AGENT_NAME:-agent}"` before the
+cycle hands off. The seal creates the rollback commit and records the
+`Skill-Edit` trailers used by the daily digest. Critical skills listed in
+`docs/contracts/critical-skills.txt` reject unattended edits; use
+`--allow-critical` only when Bo is supervising that critical edit.
+
+```bash
+/evolve                      # Run until kill switch, max-cycles, or real dormancy
+/evolve --max-cycles=5       # Cap at 5 cycles
+/evolve --dry-run            # Show what would be worked on, don't execute
+/evolve --beads-only         # Skip goals measurement, work beads backlog only
+/evolve --quality            # Quality-first mode: prioritize post-mortem findings
+/evolve --quality --max-cycles=10  # Quality mode with cycle cap
+/evolve --compile            # Mine → Defrag warmup before first cycle
+/evolve --compile --max-cycles=5 # Warm knowledge base then run 5 cycles
+/evolve --test-first         # Default strict-quality /rpi execution path
+/evolve --no-test-first      # Explicit opt-out from test-first mode
+```
+
+## Delineation vs Nightly Knowledge Compounding
+
+| Lane | Runs | Mutates code? | Mutates corpus? | Outer loop? | Budget |
+|------|------|---------------|-----------------|-------------|--------|
+| `$curate --mode=dream` | nightly, private local | **No** | **Yes (heavy)** | **Yes (convergence)** | wall-clock + plateau |
+| `evolve` | daytime, operator-driven | Yes (via `rpi`) | Yes (light) | Yes | cycle cap |
+
+**The old dream skill is retired**; out-of-session compounding moved to Gas City and the current skill surface is `$curate --mode=dream`. `/evolve` owns the live daytime code-compounding lane. Both still share the fitness-measurement substrate via `corpus.Compute` / `ao goals measure`.
+
+## Flags
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--max-cycles=N` | unlimited | Stop after `N` completed cycles |
+| `--dry-run` | off | Show planned cycle actions without executing |
+| `--beads-only` | off | Skip goal measurement and run backlog-only selection |
+| `--skip-baseline` | off | Skip first-run baseline snapshot |
+| `--quality` | off | Prioritize harvested post-mortem findings |
+| `--compile` | off | Run `ao mine` + `ao defrag` warmup before cycle 1 |
+| `--test-first` | on | Pass strict-quality defaults through to `rpi` |
+| `--no-test-first` | off | Explicitly disable test-first passthrough to `rpi` |
+| `--no-lifecycle` | off | Skip lifecycle work generators in Steps 3.4-3.6 (/test, /deps, /perf, /refactor). Falls back to manual scanning. |
+| `--mode=burst\|loop` | burst | Operator-loop; STOP refused. [loop-mode.md](references/loop-mode.md). |
+
+## Execution Steps
+
+**YOU MUST EXECUTE THIS WORKFLOW. Do not just describe it.**
+
+**FULLY AUTONOMOUS.** Read `references/autonomous-execution.md`. Every `rpi` uses `--auto`. Do NOT ask the user anything. Each cycle = complete 3-phase `rpi` run.
+
+For broad AgentOps 3.0 domain evolution across skills, CLI, hooks, docs, tests,
+beads, and knowledge, first read
+[references/domain-evolution-bootstrap.md](references/domain-evolution-bootstrap.md).
+It supplies the BDD/DDD/Hexagonal/TDD/XP control surface and the clean-room
+skill-factory guardrails.
+
+### Step 0: Setup
+
+**Stale-checkout survey guard (run FIRST).** Before any tree-reading survey: `git fetch origin && git status -sb`. If the checkout is behind/diverged AND it is a throwaway orchestration tree with no un-pushed work, `git reset --hard origin/main`. **BAN `git pull --rebase` on the survey path** — it silently no-ops against a diverged local `main`, so merged files appear "missing" and the survey investigates already-merged work.
+
+```bash
+git fetch origin && git status -sb              # survey guard — never `git pull --rebase` here
+mkdir -p .agents/evolve
+ao corpus inject --query "autonomous improvement cycle" --limit 5 2>/dev/null || true
+bash scripts/evolve-update-session-state.sh 2>/dev/null || true  # refresh derived idle_streak + mode_repeat_streak
+```
+
+`ao corpus inject` routes through the typed BC1 `CorpusReaderPort`
+(`cli/cmd/ao/corpus_reader_adapter.go`, cycle 112 productionCorpusReader),
+emitting one ranked `ports.CorpusItem` JSON record per line from
+`.agents/learnings/` by default. This closes soc-y5vh.1 — Step 0 prior-knowledge
+retrieval is now load-bearing on the typed port, not an untyped `ao lookup`
+shell-out.
+
+**Apply retrieved knowledge:** If learnings are returned, check each for applicability to the current improvement cycle. For applicable learnings, cite by filename and record: `ao metrics cite "<path>" --type applied 2>/dev/null || true`
+
+**Prior-failure injection (mandatory):** read the last 3 entries of `.agents/evolve/cycle-history.jsonl`. For any with `gate` containing `FAIL|FAILED|BLOCKED`, extract failure-surface keywords (`registry|bats|markdown|supergate|canary|coverage|toolchain`) and search `.agents/learnings/` for matching learnings. Print the top matches before work selection. Without this read path, the loop accumulates write-only ledgers and re-derives lessons each cycle. See `references/convergence-mechanics.md` for the full recipe.
+
+Before cycle recovery, load the repo execution profile contract when it exists. The repo execution profile is the source for repo policy; the user prompt should mostly supply mission/objective, not restate startup reads, validation bundle, tracker wrapper rules, or `definition_of_done`.
+
+- Locate `docs/contracts/repo-execution-profile.md` and `docs/contracts/repo-execution-profile.schema.json`.
+- Read the ordered `startup_reads` and bootstrap from those repo paths before selecting work.
+- Cache repo `validation_commands`, `tracker_commands`, and `definition_of_done` into session state.
+- If the repo execution profile is present but missing required fields, stop or downgrade with an explicit warning before cycle 1. Do not silently invent repo policy.
+- Read operating-doctrine ADRs (`docs/adr/` or `docs/decisions/`) when present — intent the loop re-reads each cycle: only operator markers stop the loop; the bead queue is a hypothesis re-confirmed against the goal, not spec; file-a-bead when a candidate is architecture disguised as bounded work.
+
+Then load the repo-local autodev program contract when it exists. The execution profile remains the repo bootstrap and landing-policy layer; `PROGRAM.md` or `AUTODEV.md` is the repo-local execution layer for the current improvement loop.
+
+- Locate `PROGRAM.md` and `AUTODEV.md`. `PROGRAM.md` takes precedence.
+- Read the resolved program before cycle recovery and cache `program_path`, `mutable_scope`, `immutable_scope`, `validation_commands`, `decision_policy`, and `stop_conditions` into session state.
+- If the program file exists but is structurally invalid, stop or downgrade with an explicit warning before cycle 1. Do not silently ignore a broken operator contract.
+- When a program contract exists, prefer work that can land wholly inside mutable scope. Do not silently widen scope around immutable files.
+
+Recover cycle number, generator streaks, and the last claimed work item from disk (survives context compaction). Initialize `CYCLE` from `cycle-history.jsonl`, recover `IDLE_STREAK`, `GENERATOR_EMPTY_STREAK`, `LAST_SELECTED_SOURCE`, and `CLAIMED_WORK_REF` from `session-state.json`.
+
+**Circuit breakers:** Time-based (60 min no productive work).
+
+**Oscillation quarantine:** Pre-populate quarantine list from cycle history (scan for goals with 3+ improved-to-fail transitions). See `references/oscillation.md`.
+
+Parse flags: `--max-cycles=N` (default unlimited), `--dry-run`, `--beads-only`, `--skip-baseline`, `--quality`, `--compile`.
+
+Track cycle-level execution state:
+
+```text
+evolve_state = {
+  cycle: <current cycle number>,
+  mode: <standard|quality|beads-only>,
+  test_first: <true by default; false only when --no-test-first>,
+  repo_profile_path: <docs/contracts/repo-execution-profile.md or null>,
+  startup_reads: <ordered repo bootstrap paths>,
+  validation_commands: <ordered repo validation bundle>,
+  tracker_commands: <repo tracker shell wrappers>,
+  definition_of_done: <repo stop predicates>,
+  program_path: <PROGRAM.md|AUTODEV.md or null>,
+  program_mutable_scope: <declared mutable paths/globs>,
+  program_immutable_scope: <declared immutable paths/globs>,
+  program_validation_commands: <ordered program validation bundle>,
+  program_decision_policy: <ordered keep/revert rules>,
+  program_stop_conditions: <ordered cycle done criteria>,
+  generator_empty_streak: <consecutive passes where all generator layers returned nothing>,
+  last_selected_source: <harvested|beads|goal|directive|testing|validation|bug-hunt|drift|feature>,
+  claimed_work: <null or work reference being worked>,
+  queue_refresh_count: <incremented after every /rpi cycle>
+}
+```
+
+Persist `evolve_state` to `.agents/evolve/session-state.json` at each cycle boundary, after work claims, after release/finalize, and during teardown. `cycle-history.jsonl` remains the canonical cycle ledger; `session-state.json` carries resume-only state that has not yet earned a committed cycle entry. Both files are **local-only** (the nested `.agents/.gitignore` denies all paths) — record durable milestones in commit messages too. See `references/cycle-history.md` for full local-only semantics.
+
+### Step 0.2: Compile Warmup (--compile only)
+
+Skip if `--compile` was not passed or if `--dry-run`. Read `references/knowledge-loop-integration.md` for the full warmup procedure (mine + defrag + signal notes).
+
+### Step 0.5: Baseline (first run only)
+
+Skip if `--skip-baseline` or `--beads-only` or baseline already exists. Read `references/fitness-scoring.md` for the baseline capture procedure.
+
+### Step 1: Kill Switch Check
+
+Run at the TOP of every cycle:
+
+```bash
+CYCLE_START_SHA=$(git rev-parse HEAD)
+# Mechanical pre-cycle gate (soc-sfjx): markers (KILL/STOP/DORMANT/HANDOFF with
+# TTL + soc-5qit non-sticky semantics), goal-regression, and prior-cycle-FAIL.
+# This is a SCRIPT the loop MUST run, not prose it can skip — externalized from
+# the old inline block so the kill-switch + revert-on-red are enforced, not
+# advisory. Adapted from the mt-olympus unbounded-evolve substrate.
+if [ -x scripts/evolve/halt-check.sh ]; then
+  if ! HALT_OUT=$(bash scripts/evolve/halt-check.sh --json); then
+    REASON=$(printf '%s' "$HALT_OUT" | jq -r '.halt_reason // "unknown"')
+    if [ "$REASON" = "prior_cycle_fail" ]; then
+      export EVOLVE_RESTORATIVE=1   # not terminal: Step 1.5 restricts scope to CI-red reduction
+    else
+      echo "halt: $REASON"; exit 0  # kill/user_halt/dormant/goal_regression -> stop this cycle
+    fi
+  fi
+else
+  # Fallback for repos without the substrate: minimal inline marker check.
+  for m in "$HOME/.config/evolve/KILL" .agents/evolve/STOP; do [ -f "$m" ] && { echo "halt: $m"; exit 0; }; done
+  [ -f .agents/evolve/DORMANT ] && { [ "$(bd ready --json 2>/dev/null | jq -r 'length // 0')" -gt 0 ] && rm -f .agents/evolve/DORMANT || { echo dormant; exit 0; }; }
+  [ -f .agents/evolve/HANDOFF ] && rm -f .agents/evolve/HANDOFF
+fi
+```
+
+**Agile-first dormancy (soc-5qit):** `DORMANT` is NEVER sticky while ready beads exist — `halt-check.sh` auto-clears it when `bd ready`/harvested work exists. KILL/STOP honor `EVOLVE_KILL_TTL_DAYS` (default 7); stale markers are surfaced and bypassed. `goal_regression` (latest cycle report `goals_passing_after < before`) halts the loop for operator attention. Heavy-context sessions write non-sticky HANDOFF; the next fire clears it and resumes. The gate is mechanical: see `scripts/evolve/halt-check.sh`.
+
+### Step 1.5: Healing-first classifier
+
+Before fitness or work selection, classify the cycle: `ao ci recent --limit 1 2>/dev/null | jq -r '.Conclusion // empty'` (typed BC2 `CIStatusPort`, soc-y5vh.2). If the last push CI was `failure`, this cycle is **restorative-only** — Step 3 takes only CI-red-reducing work (bug-type harvested items, gate-failure-fix beads, generator bug output); no promotions, features, or new-shape work until green. A `gate=FAIL` in cycle-history.jsonl auto-triggers this for cycle N+1 (and `halt-check.sh` surfaces it as `prior_cycle_fail`). See `references/convergence-mechanics.md`.
+
+**Convergence check:** evaluate the STOP predicate via the typed BC3 `ConvergenceCheckPort` — `ao loop converged --green-streak <n> --unconsumed-high-medium <n> [--fitness-baseline]` (soc-y5vh.8). Branch on `.converged` (default: CI green streak ≥ 3, HIGH+MEDIUM next-work ≤ 1, fitness baseline captured); if true, emit teardown and do NOT re-arm wakeup.
+
+### Step 2: Measure Fitness
+
+Skip if `--beads-only`. Run `scripts/evolve-measure-fitness.sh` to produce a rolling fitness snapshot at `.agents/evolve/fitness-latest.json`. Read `references/fitness-scoring.md` for the full measurement procedure, baseline capture, and post-cycle regression detection.
+
+### Step 3: Select Work
+
+Selection is a ladder, not a one-shot check — after every productive cycle, return to the TOP and re-read the queue before considering dormancy. **Read [references/work-selection-ladder.md](references/work-selection-ladder.md) for the full per-rung procedure** (programmatic `ao loop next-work` recommendation, scope filter, metronome gate, the generator rungs with their code blocks, the `--quality` inverted cascade, and the dormancy hard-gate).
+
+Ladder order (standard mode):
+- **3.0 Scope filter** (soc-5qit) — split-or-defer oversized candidates via scout-mode; never bail.
+- **3.1 Harvested** — `.agents/rpi/next-work.jsonl`, highest-value unconsumed.
+- **3.2 Open ready beads** — `bd ready`, highest priority.
+- **3.3 Failing goals + directive gaps** — skip if `--beads-only`; skip quarantined oscillators.
+- **3.4–3.6 Generators** — `/test` coverage, `/deps`+`/perf`, `/refactor`; findings → beads/queue items.
+- **3.7 Feature suggestions** grounded in repo purpose.
+
+`--quality` inverts the top (findings before goals/directives). The metronome gate blocks a rung that would repeat the trailing run's `mode` (streak ≥3).
+
+**Agile invariant (soc-5qit):** `bd ready ≥ 1` ⇒ the loop NEVER writes DORMANT and NEVER exits. The only path to DORMANT is a fully empty backlog + dry generators (3 passes). Context exhaustion → HANDOFF, not DORMANT. Under loop mode, `write-stop-marker` refuses → log blocked + operator-wait (ADR-0007).
+
+If `--dry-run`: report what would be worked on and go to Teardown.
+
+### Step 4: Execute
+
+Primary engine: `rpi` for implementation-quality work (all 3 phases mandatory). `/implement` or `/crank` only when a bead has execution-ready scope.
+
+If a repo-local `PROGRAM.md` contract is active, `rpi` will load it automatically. `evolve` must compose with that behavior, not bypass it:
+- Do not select work that is obviously outside mutable scope.
+- If a bead or goal would require edits under immutable scope, escalate it or convert it into durable follow-up work instead of launching `rpi`.
+- When work is plausibly in scope but still uncertain, let `rpi` discovery validate the fit and surface a scope escape explicitly.
+
+For a **harvested item, failing goal, directive gap, testing improvement, validation tightening task, bug-hunt result, drift finding, or feature suggestion**:
+```
+Invoke /rpi "{normalized work title}" --auto --max-cycles=1
+```
+
+For a **beads issue**:
+```
+Prefer: /rpi "Land {issue_id}: {title}" --auto --max-cycles=1
+Fallback: /implement {issue_id}
+```
+Or for an epic with children: `Invoke /crank {epic_id}`.
+
+If Step 3 created durable work instead of executing it immediately, re-enter Step 3 and let the newly-created bead item win through the normal selection order.
+
+**Mechanical-batch hint:** when the implementation phase identifies > 20 uniform per-file edits, prefer a script (`awk`/`sed`/`for f in $candidates`) over N tool-level Edit calls. See `references/mechanical-batches.md` for the decision rule and the script-first pattern.
+
+**Pre-flight schema check (architectural migrations):** if the selected work is a port/adapter migration that rewires an existing consumer, BEFORE invoking `rpi`, sample two representative consumer call sites and compare field-use against the target port surface. If the consumer reads > 20% more fields than the port projects, abort the migration cycle and convert the work into a port-widening cycle instead. The phase-2 narrowness post-mortem (`docs/learnings/2026-05-13-bc-ports-narrowness-postmortem.md`) is the encoded lesson; see `references/pre-flight-schema-check.md` for the procedure.
+
+**Operator-shape carve-out:** `AskUserQuestion` is permitted ONLY for shape decisions affecting > 50 files OR a schema/contract surface (carrier choice, struct-field shape, frontmatter-key shape). See `references/autonomous-execution.md` for the bound on this exception.
+
+### Step 4.5: Source-surface detection (pre-gate sync)
+
+Before invoking the regression gate, sync downstream artifacts when the staged diff touches binary or embedded surfaces:
+
+- `cli/**/*.go` changed → `cd cli && make build && go install ./cmd/ao`
+- `skills/**` or `hooks/**` changed → `cd cli && make sync-hooks`
+- `skills-codex/**` changed → `bash scripts/regen-codex-hashes.sh`
+
+Without these, the gate fails on stale-binary or embedded-drift errors that look like real regressions. See `references/gate-hygiene.md` for the detection recipe.
+
+**Adding or modifying a skill?** A skill touches **six derived surfaces** (registry.json SKU catalog, skill-domain-map, context-map, skill counts + the hand-added `SKILL-TIERS.md` row, codex twin, narrative counts) — regenerate them in one shot via `scripts/regen-all.sh` + the codex/count steps, never piecemeal. The most-missed is `registry.json` (stale → `contracts-sync` + `correctness(ubuntu)` fail together). See [references/new-skill-landing.md](references/new-skill-landing.md) for the full procedure, then [references/gate-hygiene.md](references/gate-hygiene.md) for the pre-push diff-scope check + pre-existing-vs-mine red triage.
+
+### Step 5: Regression Gate
+
+After execution, run the project build+test bundle. If the repo execution profile declared `validation_commands`, run them. If a repo-local program contract exists, run its `validation_commands` too, de-duplicated and in declared order after the repo bootstrap checks. Also check `if [ -f scripts/check-wiring-closure.sh ]; then bash scripts/check-wiring-closure.sh; fi`.
+
+Use the program contract's `decision_policy` as the first keep/revert rule set for the cycle:
+- if the cycle breached immutable scope, treat it as regressed
+- if program validation commands fail, treat it as regressed
+- if the decision policy declares a revert rule that fired, revert before consuming claimed work or advancing the queue
+
+Treat program `stop_conditions` as per-cycle done criteria. Do not mark claimed work consumed, completed, or productive until both the stop conditions and the regression gate pass.
+
+If not `--beads-only`, re-measure fitness to `fitness-latest-post.json` and detect regressions. The AgentOps CLI is required for fitness measurement. Read `references/fitness-scoring.md` for the full measurement, regression detection, and revert procedure.
+
+**Gate output parsing:** trust the structural marker `^.*Pass [0-9]+: (FAILED|BLOCKED)` over the trailing status line — the trailing line conflates blocking and advisory results. See `references/gate-hygiene.md`.
+
+Work finalization after the regression gate: claim it first, then keep `consumed: false` until the /rpi cycle succeeds. After the cycle's `/post-mortem` finishes, immediately re-read `.agents/rpi/next-work.jsonl` before selecting the next item. Read `references/knowledge-loop-integration.md` for full claim/release semantics.
+
+### Step 6: Log Cycle + Commit
+
+Two paths: productive cycles get committed, idle cycles are local-only.
+
+**PRODUCTIVE cycles** (result is improved, regressed, or harvested): compute quality score (if `--quality`), log via `scripts/evolve-log-cycle.sh`, commit if real changes exist. See `references/quality-mode.md` for scoring.
+
+**IDLE cycles** (nothing found even after generator layers): log via `evolve-log-cycle.sh` with `--result "unchanged"`. No git add, no commit.
+
+**Record the XP/BDD/TDD trace.** When a cycle worked a product or goal-backed gap, pass `--trace-json` to `evolve-log-cycle.sh` (or `ao loop append`) so the cycle records the continuous-evolution kernel — goal hypothesis → selected gap → Gherkin scenario → first failing proof → red/green evidence → refactor note → validation evidence → ratchet action → goal reshape — and a reviewer can reconstruct the cycle without the transcript. A trivial one-shot cycle records a `trace.exemption_reason` instead of carrying false BDD/TDD ceremony. Trace completeness is advisory, never a gate. See `references/cycle-history.md` ("XP/BDD/TDD Evidence Trace").
+
+### Step 7: Loop or Stop
+
+```bash
+while true; do
+  # Step 1 .. Step 6
+  # Stop ONLY if: operator override (KILL/STOP), max-cycles, regression-breaker,
+  # or genuine stagnation (bd ready=0 AND harvested=0 AND failing-goals=0 AND
+  # generators dry across 3 passes). Context exhaustion is NOT a stop — it's a
+  # session-handoff signal (HANDOFF marker) that the next cron-fire clears.
+  CYCLE=$((CYCLE + 1))
+done
+```
+
+**Stop reasons (soc-5qit, ALL require genuine reason — never just context size):**
+
+1. **KILL/STOP file present** — operator override.
+2. **`--max-cycles=N` cap reached**.
+3. **Genuine stagnation** — `bd ready=0 AND harvested-unconsumed=0 AND failing-goals=0 AND GENERATOR_EMPTY_STREAK>=2 AND IDLE_STREAK>=2`. Writes DORMANT, which auto-clears in Step 1 the moment `bd create` adds a new ready bead.
+4. **Regression breaker after a revert**.
+
+**Context exhaustion is NOT a stop (soc-5qit).** Heavy-context sessions write `.agents/evolve/HANDOFF` (non-sticky), log `result: "context-handoff"` to cycle-history, and exit the turn cleanly. The next cron-fire (compacted/fresh context) clears HANDOFF in Step 1 and resumes. The loop is continuous across compactions; never write DORMANT for context size. See `references/context-budget.md`.
+
+**Mandatory checkpoint #6 — session-PR threshold (NOT terminal, gates next cycle):** at `session_pr_count >= 5` (soc-waxr default), invoke `/post-mortem --deep`, wait for verdict file. PASS → continue. WARN → continue with caveat in next cycle's `notes`. FAIL or non-convergence → write STOP. Agent MUST NOT self-grade or self-write STOP. Full procedure in `references/postmortem-checkpoint.md` (soc-n75z).
+
+**Self-perpetuation modes:** the terminal-native `evolve` loop and the Claude-Code-harness `ScheduleWakeup` end-of-turn pattern are duals — both drive Step 1..Step 7 repeatedly against the same persisted state. See `references/autonomous-execution.md` for the ScheduleWakeup cadence and the rule that hard stops must NOT re-arm.
+
+Push only when productive work has accumulated:
+```bash
+if [ $((PRODUCTIVE_THIS_SESSION % 5)) -eq 0 ] && [ "$PRODUCTIVE_THIS_SESSION" -gt 0 ]; then
+  git push
+fi
+```
+
+**Drive to completion (orchestrator-merge model, soc-2drk).** Where the repo requires PRs (branch protection rejects direct `main` pushes), a productive cycle does not stop at "PR opened" — the loop is the orchestrator that drives each bead to *merged*. Ship the bead from its per-bead worktree as a PR (trailers `Closes-scenario` / `Bounded-context` / `Evidence`), wait for CI, and **squash-merge to main yourself once CI is green** (`gh pr merge <N> --squash --admin`), then `bd close` the bead and remove the worktree. **Green CI is the only merge gate** — on a quality/test red, fix-and-repush or revert; never merge red. The loop may dispatch sub-agents to implement and drives their PRs to merge too. The operator stays *on* the loop (intent + STOP marker), not *in* it (per-PR approval). This **supersedes "operator is the merge gate"** for the autonomous loop — see [ADR-0008](../../docs/adr/ADR-0008-evolve-intelligent-agile-operating-model.md).
+
+**Confirmed-MERGED gate before `bd close` (hard, not advisory).** Re-confirm `gh pr view <N> --json state -q .state` returns `MERGED` *before* `bd close` — never close on a `gh pr merge` exit code, a log line, or a batch `bd --json` query (those flake to null/0). **Close a parent epic ONLY after every child PR is independently confirmed `MERGED`**; re-query per child first, and one non-merged child aborts the epic close. (Caught two premature epic-closes in the 2026-05-31 crank session — this gate is the governance checkpoint, applied here too.) Enforce via the committed `scripts/reconcile-pr.sh <pr> <bead> [--epic <epic>]` + `scripts/check-epic-children-closed.sh <epic>` (hermetic-tested in `tests/scripts/`), not by hand.
+
+### Teardown
+
+Read `references/knowledge-loop-integration.md` for the full teardown learning extraction procedure (commit staged artifacts, run `/post-mortem`, push, report summary).
+
+A teardown `/post-mortem` is a light-touch retrospective on session-end. It does NOT substitute for the mandatory threshold checkpoint (`references/postmortem-checkpoint.md`); that one is council-gated and edge-triggered at `session_pr_count >= 5`. Never write `.agents/evolve/STOP` as a substitute for the checkpoint's verdict file — STOP without a verdict is the 2026-05-20 anti-pattern (soc-n75z).
+
+**Release-context teardown (MANDATORY when the loop ran on a release-shaped branch):**
+
+When the current branch matches `release/*`, `v*-prep`, `v*-evolve-run`, or `v\d+\.\d+*`, the teardown report MUST NOT recommend `/release` as the next step. Instead, emit the explicit pre-release checklist below — the operator must run these AND confirm green before tagging:
+
+```
+## Pre-release checklist — REQUIRED before /release
+
+The autonomous loop has stopped, but release-readiness gates have NOT been run
+during cycles. The operator MUST run the following sequence and confirm green
+before invoking /release. Do NOT skip any of these on the basis of "cycles
+were green" — fast pre-push gate ≠ full pre-push gate; goals-measure ≠
+release readiness.
+
+  [ ] 1. Regenerate ALL derived surfaces if any cobra command/flag changed:
+         bash scripts/regen-all.sh          # COMMANDS.md, registry.json, maps
+         # ADDING an `ao` command also needs the 2 surfaces regen-all only WARNS
+         # about: cli/cmd/ao/cobra_commands_test.go expectedCmds (x2 lists) +
+         # the cli-command-surface heading counts in
+         # evals/agentops-core/fixtures/cli-command-surface-smoke.sh AND
+         # evals/agentops-core/cli-command-surface-matrix.json (top/sub/all).
+         # Run the smoke fixture to read the exact new counts. (ag-jy12 will
+         # automate this.) Full procedure in
+         # [references/ao-command-landing.md](references/ao-command-landing.md)
+         git diff cli/docs/COMMANDS.md registry.json   # commit if non-empty
+
+  [ ] 2. Run the FULL pre-push gate (NOT --fast) with fail-fast OFF, so a
+         PRE-EXISTING failure (e.g. corpus-freshness) cannot mask your own
+         regressions by stopping the run early:
+         PRE_PUSH_FAIL_FAST=false bash scripts/pre-push-gate.sh
+
+  [ ] 3. Run the release-readiness gate:
+         bash scripts/ci-local-release.sh
+
+  [ ] 4. (Recommended) Smoke /evolve with the new typed read paths if BC port
+         wire-ups changed:
+         /evolve --quick --max-cycles=1 --dry-run
+
+Only after [1]–[3] pass: /release <version>
+
+If any check fails, fix the issue, re-run all four, then ship.
+```
+
+The handoff artifact (e.g., `.agents/runs/<release>/READY-TO-TAG.md`) MUST contain this checklist verbatim, unchecked, when written by the loop. The operator checks the boxes as they complete each gate; "ready to tag" means the boxes are checked, not that the loop ran cleanly.
+
+**Rationale:** cycles 170-183 of the v2.41-evolve-run shipped clean code, all unit/integration tests green, `ao goals measure` 0/30 failing for three consecutive cycles — but the loop never ran the full pre-push gate, `ci-local-release.sh`, or `generate-cli-reference.sh`. The latter was load-bearing (the branch removed a CLI flag). Per-cycle `--fast` is a smoke test, not release readiness. Operator caught the gap; this checklist makes it mechanical.
+
+## Examples
+
+**User says:** `/evolve --max-cycles=5`
+**What happens:** Evolve re-enters the full selection ladder after every `rpi` cycle and runs producer layers instead of idling on empty queues.
+
+**User says:** `/evolve --beads-only`
+**What happens:** Evolve skips goals measurement and works through `bd ready` backlog.
+
+**User says:** `/evolve --dry-run`
+**What happens:** Evolve shows what would be worked on without executing.
+
+**User says:** `/evolve --compile`
+**What happens:** Evolve runs `ao mine` + `ao defrag` at session start to surface fresh signal (orphaned research, code hotspots, oscillating goals) before the first evolve cycle. Use before a long autonomous run or after a burst of development activity.
+
+**User says:** `evolve`
+**What happens:** See `references/examples.md` for a worked overnight flow that moves through beads -> harvested work -> goals -> testing -> bug hunt -> feature suggestion before dormancy is considered.
+
+See `references/examples.md` for detailed walkthroughs.
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| Loop exits immediately | Remove `~/.config/evolve/KILL` or `.agents/evolve/STOP` |
+| Stagnation after repeated empty passes | Queue layers and producer layers were empty across multiple passes — dormancy is the fallback outcome |
+| `ao goals measure` hangs | Use `--timeout 30 --total-timeout 75` or `--beads-only` to skip |
+| Regression gate reverts | Review reverted changes, narrow scope, re-run; claimed work items must be released back to available state |
+
+See `references/cycle-history.md` for advanced troubleshooting.

+# AO-Command Landing — the surfaces a new `ao` command must regenerate
+
+Adding (or renaming/removing) an `ao` command or subcommand touches more than the
+generated CLI reference. `scripts/regen-all.sh` regenerates the bulk of the derived
+surfaces, but it only **WARNS** about two that it cannot regenerate for you — those
+are the dominant fix-and-repush cause when landing a command. Regenerate them in the
+**same pass** before opening the PR, not piecemeal.
+
+This is the command-surface parallel of [new-skill-landing.md](new-skill-landing.md)
+(the six derived surfaces a *skill* edit must regenerate).
+
+## The shortcut
+
+`scripts/regen-all.sh` regenerates `cli/docs/COMMANDS.md`, `registry.json`, the
+skill/context maps, the embedded skills, and the cli-surface inventory in one pass —
+prefer it over running the individual generators. Then hand-fix the two surfaces it
+only warns about (below), and finally run `scripts/regen-all.sh --check`.
+
+## The two surfaces regen-all only WARNS about
+
+1. **Cobra `expectedCmds` (x2 lists)** — `cli/cmd/ao/cobra_commands_test.go` hardcodes
+   the registered-command list **twice**: once in `TestCobraCommandTreeRegistration`
+   and once in `TestCobraExpectedCmdsMatchRegistration` (the second comment even says
+   "Same list as TestCobraCommandTreeRegistration"). Both `expectedCmds` slices must
+   gain the new top-level command name, or the second test fails with
+   "registered command %q is not in expectedCmds — add it to keep the list in sync".
+
+2. **`cli-command-surface` heading counts** — the generated reference's `ao` heading
+   counts (`top`/`sub`/`all`) are asserted in **two** offline canaries that must move
+   together:
+   - `evals/agentops-core/fixtures/cli-command-surface-smoke.sh` — the
+     `top_count`/`sub_count`/`all_count` literals (currently `76`/`192`/`268`).
+   - `evals/agentops-core/cli-command-surface-matrix.json` — the public canary that
+     enumerates every documented command/subcommand help page.
+
+   **Run the smoke fixture to read the exact new counts** rather than computing them by
+   hand:
+
+   ```bash
+   bash evals/agentops-core/fixtures/cli-command-surface-smoke.sh
+   # On a count mismatch it prints: unexpected command heading counts: top=.. sub=.. all=..
+   # Update the literals in the fixture (and the matrix.json cases) to the printed values.
+   ```
+
+   (Automating this regen is tracked as `ag-jy12`.)

+# Evolve Autonomous Execution Rules
+
+## Fully Autonomous
+
+Evolve runs without human intervention from start to teardown. Every `/rpi` invocation uses `--auto`. Do NOT ask the user for confirmation, clarification, or approval at any point. Do NOT pause between cycles. Do NOT summarize and wait. The user's only touchpoint is the teardown report at the very end.
+
+### Operator-shape carve-out
+
+A single, bounded exception applies. `AskUserQuestion` is permitted ONLY when the cycle has identified a **shape decision** that affects > 50 files OR touches a schema/contract surface, and where picking wrong costs > 10 minutes of rework. Examples that qualify: declaration carrier shape across a 533-file pool, frontmatter-key vs `$comment`-key vs sidecar-file choice, struct-field addition to a shared contract type. Anything that fits inside an established shape continues to be fully autonomous. The carve-out exists because a 30-second user pick can unblock 300+ file edits — but it is narrow: ask once per shape decision, then resume the autonomous loop.
+
+## ScheduleWakeup self-perpetuation (Claude-Code harness)
+
+Inside the Claude-Code harness, `/evolve` (the terminal-native loop) is not the only self-perpetuation surface. Each /evolve cycle can call `ScheduleWakeup` at end-of-turn to fire the next cycle:
+
+- Productive cycle (commit landed): `delaySeconds=270` keeps the prompt cache warm.
+- Scout cycle: `delaySeconds=600` — bigger gap, no cache reload cost since context isn't reused.
+- Idle cycle: `delaySeconds=1800` — coarse poll for fresh signal.
+
+Hard stops MUST NOT call `ScheduleWakeup`: KILL/STOP files, dormancy reached, `CONTEXT_BUDGET_EXHAUSTED` (see `references/context-budget.md`), or `--max-cycles` cap hit. When dormancy fires (Step 3 hard-gate), `/evolve` writes `.agents/evolve/DORMANT` and Step 1 short-circuits on subsequent fires before any further tool calls — this is the operational enforcement of the "no ScheduleWakeup on dormancy" rule (see `references/cycle-history.md` for the marker semantics). The terminal-mode `/evolve` loop and the Claude-Code `ScheduleWakeup` loop are duals: both drive Step 1..Step 7 repeatedly, both honor the same kill switches and stop conditions, both persist resume state via `.agents/evolve/session-state.json`.
+
+## Each Cycle = Complete /rpi Run
+
+All 3 phases (discovery → implementation → validation). Never invoke a partial RPI. If a task is too large for one cycle, break it into smaller sub-tasks during discovery and let `/crank` handle the waves. Evolve's job is to keep the loop turning, not to micro-manage individual tasks.
+
+## Break Large Work into Sub-RPI Cycles
+
+When work selection identifies a massive task (7+ issues, multi-subsystem scope), decompose it during `/rpi`'s discovery phase into an epic with waves. One evolve cycle = one `/rpi` run = one complete lifecycle. If the epic is too large for a single session, `/rpi`'s built-in retry and `--from=` resume handle continuation.
+
+## Respect Repo-Local Program Contracts
+
+When `PROGRAM.md` or `AUTODEV.md` exists, treat it as a hard operational constraint for cycle selection and keep/revert decisions:
+- prefer work that can plausibly land inside mutable scope
+- do not intentionally select work that requires immutable-scope edits
+- treat out-of-scope work as escalation or backlog material, not permission to widen scope in place
+- let `/rpi` enforce the active program contract during execution, then use its validation and decision policy during the evolve regression gate
+
+## Anti-Patterns (DO NOT)
+
+| Anti-Pattern | Why It's Wrong | Correct Behavior |
+|--------------|----------------|------------------|
+| Ask the user anything during execution | Evolve is fully autonomous — questions break the loop | Make best judgment, report in teardown. Exception: shape decisions affecting > 50 files or schema/contract surfaces (see "Operator-shape carve-out" above) |
+| Stop after one `/rpi` cycle and summarize | Evolve loops until kill switch, max-cycles, or dormancy | Increment cycle and re-enter Step 1 |
+| Run `/rpi` without `--auto` | Non-auto `/rpi` has human gates that halt the loop | Always pass `--auto` to `/rpi` |
+| Run partial `/rpi` (skip validation) | Each cycle must be a complete 3-phase lifecycle | Let `/rpi` run all 3 phases autonomously |
+| Pause between cycles to explain progress | The user wants results, not narration | Log cycle results, immediately start next cycle |
+| Treat "no queued work" as "stop" | Generator layers (testing, validation, drift, features) produce work | Run all generator layers before considering dormancy |
+| Select work that obviously violates `PROGRAM.md` | Scope escape is a tracked outcome, not a license to widen the loop | Escalate or re-queue out-of-scope work and keep selection inside mutable scope |

+# How Compounding Works
+
+Two mechanisms feed the loop:
+
+**1. Knowledge flywheel (each cycle is smarter):**
+```
+Session 1:
+  ao lookup --query "recent learnings" (nothing yet)  → cycle runs blind
+  /rpi fixes test-pass-rate       → post-mortem runs ao forge
+  Learnings extracted: "tests/skills/run-all.sh validates frontmatter"
+
+Session 2:
+  ao lookup --query "recent learnings" (loads Session 1 learnings)  → cycle knows about frontmatter validation
+  /rpi fixes doc-coverage                → approach informed by prior learning
+  Learnings extracted: "references/ dirs need at least one .md file"
+```
+
+**2. Work harvesting (each cycle discovers the next):**
+```
+Cycle 1: /rpi fixes test-pass-rate
+  → post-mortem harvests: "add missing smoke test for /evolve" → next-work.jsonl
+
+Cycle 2: all GOALS.yaml goals pass
+  → /evolve reads next-work.jsonl (exact repo first, then cross-repo '*', then legacy)
+  → picks "add missing smoke test"
+  → /rpi fixes it → post-mortem harvests: "update SKILL-TIERS count"
+
+Cycle 3: reads next-work.jsonl → picks "update SKILL-TIERS count" → ...
+```
+
+The loop keeps running as long as post-mortem keeps finding follow-up work. Each /rpi cycle generates next-work items from its own post-mortem. The system feeds itself.
+
+**Priority cascade:**
+```
+next-work.jsonl (harvested / queued work)    → exact repo first, then `*`, then legacy
+Open beads (bd ready)                        → durable tracked backlog
+GOALS.yaml directives and failing goals      → explicit fitness gaps
+Testing improvements                         → synthesize coverage / regression-test work
+Validation + bug-hunt passes                 → tighten gates, discover real defects
+Hotspots / TODO / drift / stale docs         → mine weak signals into work
+Feature suggestions                          → propose new product work when remediation dries up
+multiple empty queue + generator passes      → last-resort dormancy
+60-minute circuit breaker                    → stop if no productive cycle in 60 min
+kill switch                                  → immediate stop
+```
+
+The loop does NOT stop just because goals are met or the current queue is empty. It re-reads harvested work after every `/rpi` cycle, runs generator layers when queues are empty, and only stops after repeated empty queue + generator passes. Idle cycles are NOT committed to git — only appended locally. The idle streak is re-derived from disk at each session start, while `session-state.json` carries pending claim/generator resume state. Use the kill switch for intentional stops.

+# Context Budget — Session Handoff, Not a Stop (soc-5qit)
+
+**Prior framing (deprecated):** context exhaustion was a third stop reason that wrote sticky `DORMANT` and ended the run.
+
+**Current framing (soc-5qit, 2026-05-21):** context exhaustion is a *session-handoff signal*. The loop is continuous across compactions; a heavy session writes a non-sticky `HANDOFF` marker, exits the current cron-fire turn cleanly, and the NEXT cron-fire (running on harness-compacted or fresh context) automatically clears HANDOFF in Step 1 and resumes.
+
+This change was forced by an operator failure mode (2026-05-20→21): a cron-driven /evolve session shipped 6 PRs, accumulated context, then sticky-DORMANT'd despite 10+ unblocked P1 beads in `bd ready`. The prior design treated "this Claude session can't safely take on more work" as "the work itself is done" — a category error. The cron loop spans many sessions; one session's context is irrelevant to whether the backlog has work.
+
+## Why it's a real failure mode (still true)
+
+A long session that has shipped 5+ productive cycles accumulates context: read files cache, tool-result trails, prior `/rpi` discovery findings. When cycle N+1 selects an item that requires a fresh deep read of unfamiliar surfaces, the cycle either:
+
+- Forces a scout-mode return because the context is too heavy to execute (correct outcome, but the skill must not treat this as terminal).
+- Attempts execution and produces shallow work that the regression gate or self-review catches (recovery cost > the cycle's value).
+
+The fix is to surface this as a handoff to the next session, not stop the loop.
+
+## The counter and the signal
+
+Maintain `context_streak` in `.agents/evolve/session-state.json`. Increment when ANY of these are true at end-of-cycle:
+
+- Cycle result is `scout` AND the scout's `disposition` says "context too heavy"
+- Cycle result is `harvested` AND the harvest was a context-budget defer (vs. a feature-suggestion)
+- The /rpi cycle aborted before commit because discovery context overflowed
+
+Reset to 0 when a productive `improved` cycle lands.
+
+```bash
+context_streak=$(jq -r '.context_streak // 0' .agents/evolve/session-state.json)
+
+if [ "$context_streak" -ge 2 ]; then
+  echo "CONTEXT_BUDGET_EXHAUSTED after $context_streak heavy-context cycles."
+  echo "Writing HANDOFF (non-sticky) and exiting this cron-fire turn."
+  # HANDOFF carries ONLY the parked work refs and the timestamp.
+  # It is NOT a sticky stop. Step 1 of the next cron-fire clears it automatically.

+
+**Critical:** the HANDOFF marker does NOT block future cron-fires. Step 1 of the next /evolve turn clears it and continues normal work selection.
+
+## Handoff message (logged, not gated)
+
+When the context-handoff fires, write a cycle-history entry that names the parked work concretely:
+
+```json
+{"cycle": N, "result": "context-handoff",
+ "selected_source": "<source>", "work_ref": "<ref>",
+ "milestone": "Context-handoff after 2 heavy cycles. Parked: <work refs>. Next cron-fire (compacted/fresh) resumes."}
+```
+
+The next operator session reads this entry, knows what was parked, and can either continue manually or wait for the next cron-fire to handle it.
+
+## Configurable threshold
+
+Default `context_streak` threshold is 2. Override with `EVOLVE_CONTEXT_STREAK_LIMIT=N` env var if a particular session needs to tolerate more heavy cycles (rare).
+
+## ScheduleWakeup interaction
+
+When running the Claude-Code-harness self-perpetuation mode (see `references/autonomous-execution.md`), a context-handoff exit MUST NOT call `ScheduleWakeup` from the same heavy-context turn — re-firing would re-load the heavy context. The cron schedule (or operator's external trigger) handles the re-fire. By the time the next cron-fire runs, the harness has compacted or the session has rolled, and HANDOFF auto-clears.
+
+## What this is NOT
+
+- **Not a stop reason.** Stop reasons are operator override, max-cycles cap, regression-breaker, and genuine stagnation (bd ready=0 AND harvested=0 AND failing-goals=0 AND generators dry).
+- **Not a sticky marker.** DORMANT is sticky-with-auto-clear-on-new-work; HANDOFF is fully non-sticky and clears on next read.
+- **Not a "the work is done" signal.** It explicitly says "this session can't safely continue; the work is parked." The next session does the work.
+
+## Cross-reference
+
+- `SKILL.md` Step 1 — HANDOFF auto-clear on cron-fire-N+1
+- `SKILL.md` Step 7 — context exhaustion explicitly removed from stop reasons list
+- `references/scout-mode.md` — scope-filter splits or defers; never bails

+# Convergence Mechanics — How the Loop Compounds Instead of Drifts
+
+The /evolve loop only compounds when each cycle reads prior cycles' outcomes and lets them change behavior. Append-only ledgers that no step reads are write-only artifacts — they accumulate without compounding.
+
+This reference documents the four feedback mechanisms that turn raw cycle output into next-cycle behavior change.
+
+## Mechanism 1: Step 0 reads prior-failure surface
+
+In Step 0 (Setup), after `mkdir -p .agents/evolve`, the loop reads the last 3 entries of `cycle-history.jsonl`. For any entry where `gate` field contains a FAIL marker, it extracts the failure surface (e.g. "registry-check stale", "bats-tests goals-validate") and injects the matching learning before work selection.
+
+```bash
+last3=$(scripts/evolve-read-cycle-history.sh recent 3)  # routes through BC3 LoopReaderPort (soc-y5vh.4)
+fail_surfaces=$(echo "$last3" | jq -r 'select(.gate | test("FAIL|FAILED|BLOCKED")) | .gate' 2>/dev/null)
+if [ -n "$fail_surfaces" ]; then
+    # Search learnings for surface keywords; print whichever match
+    keywords=$(echo "$fail_surfaces" | grep -oE 'registry|bats|markdown|supergate|canary|coverage|toolchain' | sort -u)
+    for kw in $keywords; do
+        ao lookup --query "$kw failure" --limit 2 2>/dev/null || \
+            find .agents/learnings -name "*$kw*.md" -mtime -30 | head -2
+    done
+fi
+```
+
+Without this, the 2026-05-07 CI-toil learning sat for 7 days while I burned 5 cycles re-hitting the same `registry.json` non-determinism. Reading the learning at Step 0 would have surfaced the `git ls-files` fix on cycle 45.
+
+## Mechanism 2: Step 1.5 healing-first classifier
+
+Before Step 2 (measure fitness) and Step 3 (select work), the loop classifies the cycle:
+
+```bash
+# Step 1.5: healing-first classifier — routes through BC2 CIStatusPort
+# (cli/cmd/ao/ci_status_adapter.go, cycle 117 productionCIStatus) per
+# soc-y5vh.2. No inline gh shell-outs.
+last_ci=$(ao ci recent --limit 1 2>/dev/null | jq -r '.Conclusion // empty')
+if [ "$last_ci" = "failure" ]; then
+    CYCLE_MODE="restorative"
+    # Read failure surface, search for matching learning
+    # (see Mechanism 1)
+    # Selection ladder downgrade: skip Step 3.1 (harvested) for feature
+    # work; only allow harvested items typed bug/fix/ci-failure.
+else
+    CYCLE_MODE="feature"
+fi
+```
+
+Restorative cycles ONLY take work that reduces CI red. New PG4 promotions, feature additions, doc growth — all blocked until `last_ci=success`.
+
+This eliminates the cycle-46-47 pattern where I added new evidence files onto a CI-red base.
+
+## Mechanism 3: Hypothesis tracking for skill changes
+
+When a cycle edits `skills/evolve/SKILL.md`, it MUST append to the hypothesis
+ledger through the typed BC3 `HypothesisLedgerPort` (soc-y5vh.8):
+
+```bash
+ao loop hypothesis append --id "H<cycle>.<patch>" --cycle-landed N --check-at-cycle $((N+15)) \
+  --patch "<one-line>" --hypothesis "<expected effect>" --measure "<how to verify>"
+```
+
+This routes through `productionHypothesisLedger` instead of a raw append to
+`.agents/evolve/hypotheses.jsonl`; the port rejects empty and duplicate IDs.
+At `check_at_cycle`, the loop reads the ledger with `ao loop hypothesis list`
+(one JSON record per line), evaluates each PENDING row's `measure`, and
+writes the verdict (VERIFIED / FALSIFIED). Falsified hypotheses are
+revisited: either the patch is wrong, or the measurement was wrong.
+
+Without this, cycle 45's 6 patches landed unmeasured and 2 of them (H45.2 source-surface auto-rebuild, H45.3 grep-based gate parsing) were silently inert for the next 5 cycles — text in SKILL.md but no harness automation behind them.
+
+## Mechanism 4: Convergence criteria with a STOP
+
+`.agents/evolve/session-convergence.json` records the terminal state; the STOP
+decision is evaluated through the typed BC3 `ConvergenceCheckPort` (soc-y5vh.8):
+
+```bash
+ao loop converged --green-streak "$STREAK" --unconsumed-high-medium "$HM" --fitness-baseline
+# emits {converged, ci_green_streak, unconsumed_high_medium, fitness_baseline_captured, reasons}
+```
+
+The predicate is pure — the loop supplies the evidence it already has
+(`ao ci recent` for the streak, the next-work findings count, the
+fitness-baseline flag). The criteria are met when all hold:
+
+- CI Validate green for the last 3 pushes (green streak ≥ 3)
+- HIGH+MEDIUM unconsumed next-work entries ≤ 1
+- a fitness baseline has been captured
+
+When `ao loop converged` reports `converged: true`, the loop emits a teardown
+report and does NOT call `ScheduleWakeup`. The wakeup chain terminates. The
+autonomous loop is bounded by criteria, not by wakeup count. `reasons` names
+every unmet criterion when `converged` is false.
+
+Without an explicit STOP, the loop drifts indefinitely. With STOP, it converges.
+
+## Anti-drift rules
+
+1. **Restorative-only after red.** Any cycle whose `gate` field has FAIL → cycle N+1 is restorative.
+2. **3 consecutive restorative without restoration → escalate.** Don't silently grind.
+3. **Scope shift resets the streak.** If the operator broadens the convergence target mid-session, reset `ci-green-streak` counter to 0.
+
+## Why this is the load-bearing change
+
+Cycles 44-50 wrote ~30 KB of bookkeeping (cycle-history, learning, retro, evidence, hypotheses) but produced ~0 compounded behavior — every cycle had to re-derive the lesson cycle 44 should have surfaced. The compounding lives in the read path, not the write path. These four mechanisms make the read path real.

+# Cycle History Format and Recovery Protocol
+
+## Compaction Resilience
+
+The evolve loop MUST survive context compaction. Every productive cycle appends
+to its ledger artifacts before proceeding. `cycle-history.jsonl` is the
+on-disk recovery point for cycle numbering, and `.agents/evolve/session-state.json`
+is the on-disk resume point for pending queue claims, queue refresh count, and
+generator-empty streaks.
+
+### Local-Only Status (Not Git-Tracked)
+
+Both `cycle-history.jsonl` and `session-state.json` are **local-only files**.
+The repository's nested `.agents/.gitignore` denies all paths via `*` (with
+only `!.gitignore` re-allowed), which overrides the outer `.gitignore`
+allowlists at the repo root. Aspirational allowlist entries for
+`!/.agents/evolve/cycle-history.jsonl` and `!/.agents/evolve/session-state.json`
+exist in the outer `.gitignore` but have no effect because the nested
+deny wins per gitignore precedence rules.
+
+Implication for the cycle protocol:
+
+- These files survive **session compaction** (recovered from disk on the next
+  invocation), but they do **not** survive cloning or shared with peers.
+- Important per-cycle milestones (e.g. baseline-capture results, regression
+  events, convergence-criterion transitions) MUST also be recorded in
+  **commit messages** so they remain in tracked git history.
+- Do not depend on cycle-history.jsonl as a cross-clone authoritative ledger.
+  Treat it as a session journal that helps the next-cycle bootstrap.
+
+## Cycle History JSONL Format
+
+Append one line per cycle to `.agents/evolve/cycle-history.jsonl`.
+
+### Canonical Schema
+
+All new entries MUST use this schema:
+
+```json
+{
+  "cycle": 123,
+  "target": "goal-id-or-idle",
+  "result": "improved|regressed|unchanged|harvested|quarantined",
+  "sha": "abc1234",
+  "canonical_sha": "abc1234",
+  "timestamp": "2026-02-23T12:00:00-05:00",
+  "goals_passing": 59,
+  "goals_total": 59
+}
+```
+
+**Field standardization:**
+- Use `target` (not `goal_id`) — this is what recent cycles already use
+- Use `sha` as the compatibility alias for `canonical_sha`
+- Use `canonical_sha` for the implementation commit the cycle actually delivered
+- Use `log_sha` only when the bookkeeping/log commit is distinct from `canonical_sha`
+- Always include `goals_passing` and `goals_total` — enables trajectory plotting
+- Optional fields: `quality_score` (quality mode), `idle_streak` (idle cycles), `parallel` + `goal_ids` (parallel mode)
+
+**Legacy field names:** Older entries may use `goal_id` instead of `target` and `commit_sha` instead of `sha`. Tools reading cycle-history.jsonl should handle both conventions.
+
+**Sequential cycle entry:**
+```jsonl
+{"cycle": 1, "target": "test-pass-rate", "result": "improved", "sha": "abc1234", "canonical_sha": "abc1234", "goals_passing": 18, "goals_total": 23, "timestamp": "2026-02-11T21:00:00Z"}
+{"cycle": 2, "target": "doc-coverage", "result": "regressed", "sha": "def5678", "canonical_sha": "def5678", "log_sha": "fedcba9", "goals_passing": 17, "goals_total": 23, "timestamp": "2026-02-11T21:30:00Z"}
+```
+
+**Idle cycle entry** (not committed to git):
+```jsonl
+{"cycle": 3, "target": "idle", "result": "unchanged", "timestamp": "2026-02-11T22:00:00Z"}
+```
+
+**Parallel cycle entry** (use `goal_ids` array and `parallel: true`):
+```jsonl
+{"cycle": 4, "goal_ids": ["test-pass-rate", "doc-coverage", "lint-clean"], "result": "improved", "sha": "ghi9012", "goals_passing": 22, "goals_total": 23, "parallel": true, "timestamp": "2026-02-11T22:30:00Z"}
+```
+
+### Mandatory Fields
+
+Every productive cycle log entry MUST include:
+
+| Field | Description |
+|-------|-------------|
+| `cycle` | Cycle number (1-indexed) |
+| `target` | Target goal ID, or `"idle"` for idle cycles |
+| `result` | One of: `improved`, `regressed`, `unchanged`, `harvested`, `quarantined` |
+| `sha` | Compatibility alias for the implementation SHA (omitted for idle cycles) |
+| `canonical_sha` | Implementation commit the cycle actually delivered |
+| `goals_passing` | Count of goals with result "pass" (omitted for idle cycles) |
+| `goals_total` | Total goals measured (omitted for idle cycles) |
+| `timestamp` | ISO 8601 timestamp |
+
+`log_sha` is optional and should only be written when the log/bookkeeping commit
+differs from `canonical_sha`. These fields enable fitness trajectory plotting
+without losing retrospective provenance.
+
+### XP/BDD/TDD Evidence Trace (optional `trace` object)
+
+A productive cycle MAY record a `trace` object capturing the
+continuous-evolution kernel — the evidence a reviewer needs to reconstruct
+the cycle **without reading the transcript**. The kernel shape is:
+
+> goal hypothesis → selected gap → Gherkin scenario → first failing proof →
+> red evidence → green evidence → refactor note → validation evidence →
+> ratchet action → goal reshape decision
+
+```json
+{
+  "cycle": 200,
+  "target": "test-pass-rate",
+  "result": "improved",
+  "sha": "abc1234",
+  "canonical_sha": "abc1234",
+  "goals_passing": 60,
+  "goals_total": 60,
+  "timestamp": "2026-05-16T12:00:00Z",
+  "trace": {
+    "goal_hypothesis": "raising test-pass-rate lifts overall fitness",
+    "selected_gap": "loop cycle ledger carries no evidence trace",
+    "gherkin": "Feature: trace\n  Scenario: reviewer reconstructs a cycle",
+    "first_failing_proof": "go test ./internal/ports -run TraceCompleteness  # FAIL",
+    "red_evidence": "TestTraceCompleteness_FullTraceIsComplete red: undefined CycleTrace",
+    "green_evidence": "TestTraceCompleteness_* pass (5/5)",
+    "refactor_note": "extracted requiredTraceFields table; no behavior change",
+    "validation_evidence": "cd cli && go test ./... green; bats evolve-log-cycle.bats 10/10",
+    "ratchet_action": "ao ratchet record implement",
+    "goal_reshape": "goal unchanged; gap closed — fold trace into next epic's audit"
+  }
+}
+```
+
+**Trace fields** (all strings, all `omitempty`):
+
+| Field | Records |
+|-------|---------|
+| `goal_hypothesis` | The goal/fitness hypothesis the cycle is testing |
+| `selected_gap` | The specific gap chosen from the queue/generator |
+| `gherkin` | The Given/When/Then scenario the slice satisfies |
+| `first_failing_proof` | The command/assertion that fails before the change |
+| `red_evidence` | Observed failing-test output (the RED state) |
+| `green_evidence` | Observed passing-test output (the GREEN state) |
+| `refactor_note` | The refactor step — record `"none"` when there is none |
+| `validation_evidence` | Independent validation commands and their results |
+| `ratchet_action` | The `ao ratchet record …` action taken |
+| `goal_reshape` | Whether the goal stayed, narrowed, or was replaced |
+
+**Trivial-cycle exemption.** A tiny one-shot bookkeeping change (a typo fix,
+a dependency bump) does NOT need full BDD/TDD ceremony. Instead of silently
+omitting the trace fields, record an explicit `exemption_reason`:
+
+```json
+{"cycle": 201, "target": "idle", "result": "unchanged", "timestamp": "...",
+ "trace": {"exemption_reason": "trivial one-shot typo fix; no Gherkin or failing proof appropriate"}}
+```
+
+A trace with a non-empty `exemption_reason` is **exempt** — no other field is
+expected. A trace with neither `exemption_reason` nor the evidence fields is
+**incomplete**: `ports.TraceCompleteness` (Go) reports which required fields
+are missing.
+
+**Completeness is advisory, never blocking.** `TraceCompleteness` is a pure
+helper for reports and audits; it is deliberately NOT wired into
+`ao loop verify` or `scripts/check-evolve-cycle-logging.sh`. The `trace`
+object is recorded as-is. This keeps the loop honest about its own evidence
+without making loop-shape a hard gate before real cycle output conforms.
+
+**Writing a trace.** Both writers accept it:
+
+```bash
+# canonical script writer — file path, inline JSON, or - for stdin
+bash scripts/evolve-log-cycle.sh --cycle "$CYCLE" --target "$TARGET" \
+  --result improved --canonical-sha "$SHA" --cycle-start-sha "$START" \
+  --goals-passing "$P" --goals-total "$T" --trace-json cycle-trace.json
+
+# typed BC3 LoopWriterPort
+ao loop append --mode evolve --result improved --trace-json cycle-trace.json
+```
+
+`ao loop history` emits the `trace` object back as part of each `CycleEntry`,
+so the report surface carries the evidence with no extra step.
+
+### Session-State Sidecar
+
+Persist the non-ledger loop state to `.agents/evolve/session-state.json`:
+
+```json
+{
+  "cycle": 124,
+  "generator_empty_streak": 1,
+  "last_selected_source": "testing",
+  "queue_refresh_count": 17,
+  "claimed_work": {
+    "ref": "source_epic=ag-123:item=Add smoke test",
+    "claimed_by": "evolve:cycle-124",
+    "claimed_at": "2026-03-08T10:15:00Z"
+  }
+}
+```
+
+On resume:
+1. recover `cycle` from `cycle-history.jsonl`
+2. recover generator and claim state from `session-state.json`
+3. if `claimed_work` exists, inspect the queue entry:
+   - if the prior cycle succeeded, finalize it as consumed
+   - if the prior cycle failed or is ambiguous, release the claim and continue
+
+### Substantive-Delta Rule
+
+Do not record `result: "improved"` when a cycle produces no non-agent repo delta.
+If the cycle touched only `.agents/` artifacts or otherwise made no substantive
+repo change, rewrite the outcome to `unchanged` and keep it local-only. This
+prevents ledger churn from being misread as product progress.
+
+### Telemetry
+
+Log telemetry at the end of each cycle:
+```bash
+bash scripts/log-telemetry.sh evolve cycle-complete cycle=${CYCLE} score=${SCORE} goals_passing=${PASSING} goals_total=${TOTAL}
+```
+
+### Compaction-Proofing: Commit After Productive Cycles
+
+Only **productive cycles** (improved, regressed, harvested) are committed. Idle
+cycles are appended to cycle-history.jsonl locally but NOT committed — they are
+disposable if compaction occurs, and the idle streak is re-derived from disk at
+session start. Producer-layer exhaustion is tracked in `session-state.json`, not
+by stopping early.
+
+```bash
+# Productive cycle: log via the canonical writer, then commit
+bash scripts/evolve-log-cycle.sh \
+  --cycle "$CYCLE" \
+  --target "$TARGET" \
+  --result "$OUTCOME" \
+  --canonical-sha "$(git rev-parse --short HEAD)" \
+  --cycle-start-sha "$CYCLE_START_SHA" \
+  --goals-passing "$PASSING" \
+  --goals-total "$TOTAL"
+
+# Parallel productive cycle:
+bash scripts/evolve-log-cycle.sh \
+  --cycle "$CYCLE" \
+  --target "parallel-wave" \
+  --goal-ids "${goal_ids_csv}" \
+  --parallel \
+  --result "$OUTCOME" \
+  --canonical-sha "$(git rev-parse --short HEAD)" \
+  --goals-passing "$PASSING" \
+  --goals-total "$TOTAL"
+
+# Idle or no-delta cycle: append locally, do NOT commit
+bash scripts/evolve-log-cycle.sh --cycle "$CYCLE" --target "idle" --result "unchanged" >/dev/null
+# No git add, no git commit
+```
+
+### 60-Minute Circuit Breaker
+
+At session start (Step 0), after recovering the idle streak, check the timestamp
+of the last productive cycle. If it was more than 60 minutes ago, go directly to
+Teardown. This prevents runaway sessions that accumulate empty queue/generator
+passes without producing value.
+
+```bash
+LAST_PRODUCTIVE_TS=$(grep -v '"idle"\|"unchanged"' .agents/evolve/cycle-history.jsonl 2>/dev/null \
+  | tail -1 | jq -r '.timestamp // empty')
+# If >3600s since last productive cycle AND timestamp parsed correctly: CIRCUIT BREAKER → Teardown
+# Guard: LAST_EPOCH > 1e9 prevents false trigger on date parse failure
+```
+
+## Recovery Protocol
+
+On session restart or after compaction:
+
+1. Read `.agents/evolve/cycle-history.jsonl` to find last completed cycle number
+2. Set `evolve_state.cycle` to last cycle + 1
+3. Resume from Step 1 (kill switch check)
+4. Preserve existing `.agents/evolve/fitness-baselines/goals-<hash>/` directories; do not regenerate the current era baseline if its directory already contains a JSON snapshot
+
+## Kill Switch
+
+Three paths, checked at every cycle boundary:
+
+| File | Purpose | Who Creates It |
+|------|---------|---------------|
+| `~/.config/evolve/KILL` | Permanent stop (outside repo) | Human |
+| `.agents/evolve/STOP` | One-time local stop | Human or automation |
+| `.agents/evolve/DORMANT` | Sticky dormancy after Step 3 hard-gate fired | `/evolve` itself |
+
+To stop /evolve:
+```bash
+echo "Taking a break" > ~/.config/evolve/KILL    # Permanent
+echo "done for today" > .agents/evolve/STOP       # Local, one-time
+```
+
+The `DORMANT` marker is written by `/evolve` when both queue layers and generator layers come up empty across 3 consecutive passes (the Step 3 hard-gate). Its purpose is to prevent post-dormancy cron fires from re-entering the full skill body — once the marker exists, Step 1 short-circuits with zero further tool calls. The marker contains three lines: cycle number, ISO timestamp, reason.
+
+To re-enable:
+```bash
+rm ~/.config/evolve/KILL
+rm .agents/evolve/STOP
+rm .agents/evolve/DORMANT
+```
+
+The operator typically removes `DORMANT` either when (a) new scope arrives that didn't fit any rung of the ladder when dormancy fired, or (b) the underlying ledger has gained enough new entries that generator layers will produce new work. There is no auto-clear — dormancy is sticky by design.
+
+## Flags Reference
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--max-cycles=N` | unlimited | Optional hard cap. Without this, loop runs forever. |
+| `--test-first` | off | Pass `--test-first` through to `/rpi` -> `/crank` |
+| `--dry-run` | off | Measure fitness and show plan, don't execute |
+| `--skip-baseline` | off | Skip cycle-0 baseline sweep |
+| `--parallel` | off | Enable parallel goal execution via /swarm per cycle |
+| `--max-parallel=N` | 3 | Max goals to fix in parallel (cap: 5). Only with `--parallel`. |
+
+## Troubleshooting
+
+| Problem | Cause | Solution |
+|---------|-------|----------|
+| `/evolve` exits immediately with "KILL SWITCH ACTIVE" | Kill switch file exists | Remove `~/.config/evolve/KILL` or `.agents/evolve/STOP` to re-enable |
+| "No goals to measure" error | GOALS.yaml missing or empty | Create GOALS.yaml in repo root with fitness goals (see goals-schema.md) |
+| Cycle completes but fitness unchanged | Goal check command is always passing or always failing | Verify check command logic in GOALS.yaml produces exit code 0 (pass) or non-zero (fail) |
+| Regression revert fails | Multiple commits in cycle or uncommitted changes | Check cycle-start SHA in fitness snapshot, commit or stash changes before retrying |
+| Harvested work never finalizes | Queue item was claimed but cycle did not clear/finalize it | Inspect `claim_status`, `claimed_by`, and `claimed_at`; successful cycles consume, failed cycles release |
+| Loop stops after empty queues | Generator streak was exhausted too quickly or `--max-cycles` was set | Verify producer layers ran, inspect `session-state.json`, and omit `--max-cycles` for overnight runs |

+# Domain Evolution Bootstrap
+
+Use this reference when `/evolve` is asked to reshape AgentOps skills, CLI,
+hooks, docs, tests, beads, or knowledge as one software-factory system.
+
+## Product Frame
+
+AgentOps is the SDLC control plane and context compiler for LLM agents. The
+narrow waist is:
+
+- BDD/Gherkin for observable intent;
+- DDD for shared names and bounded contexts;
+- Hexagonal architecture for ports and adapters;
+- TDD for local proof of done;
+- XP for small vertical slices;
+- CI, SRE, ADRs, and provenance for repeated trust and memory.
+
+Do not treat a skill, hook, or command as valuable by itself. It is valuable
+only when it advances the factory loop: intent, boundary, proof, evidence, and
+compounding context.
+
+## Bootstrap Sequence
+
+1. Read current direction from `PRODUCT.md`, `GOALS.md`,
+   `docs/cdlc.md`, and `docs/architecture/operating-loop.md`.
+2. Validate the durable control artifacts:
+
+   ```bash
+   bash scripts/check-agentops-domain-evolution-plan.sh
+   ```
+
+3. Select one domain and one vertical slice from:
+   - `docs/reference/agentops-domain-evolution-bdd.md`
+   - `docs/reference/agentops-skill-domain-map.md`
+   - `docs/reference/agentops-hexagonal-architecture-map.md`
+   - `docs/reference/agentops-domain-evolution-plan.md`
+4. Use `skill-builder` and `skill-auditor` for skill changes. Use
+   `skills/skill-auditor/scripts/score_agentops_skill.py` to choose the
+   smallest score-improving patch.
+5. Keep CLI and hook changes behind typed ports or existing validation scripts.
+6. Run focused validation before selecting the next slice.
+
+## Hard Rules
+
+- No broad rewrite before a Gherkin row, domain, and first proof are named.
+- No third-party content copying; use clean-room structural observations only.
+- No shipped skill deletion until replacement workflow and validation evidence
+  exist.
+- No shell-only read path when a typed port already exists.
+- No unattended run from a dirty canonical root or stale installed `ao` binary.

+Feature: Evolve runs a goal-driven compounding loop
+  As the autonomous improvement loop
+  I want each cycle gated, work-selected by ladder, and shipped as a bounded slice
+  So that the repo compounds toward GOALS.md without the agent ever self-halting
+
+  Background:
+    Given an operator-set intent (GOALS.md, ADRs, the bead queue)
+
+  Scenario: A mechanical pre-cycle gate decides continue or halt
+    When a cycle starts
+    Then scripts/evolve/halt-check.sh runs first
+    And the loop continues unless an operator marker / goal-regression / prior-FAIL fires
+
+  Scenario: Work selection walks the ladder
+    When the loop selects work
+    Then it prefers harvested next-work, then ready beads, then failing goals, then generators
+    And it declines operator-shape work (epics/release/decisions) per ADR-0008
+
+  Scenario: One bounded slice per cycle, reverted on red
+    When the loop works a selected item
+    Then it ships a single bounded slice via /rpi, gated by build + test + lint
+    And it reverts the slice rather than landing red
+
+  Scenario: The loop never self-halts
+    When the loop is blocked or out of bounded work
+    Then it logs `ao loop blocked` and continues or operator-waits
+    And it never writes a STOP/DORMANT marker itself (operator-only, ADR-0007)

+# /evolve Examples
+
+## Infinite Autonomous Improvement
+
+**User says:** `/evolve`
+
+**What happens:**
+1. Agent checks kill switch files (none found, continues).
+2. Agent loads the repo execution profile, reads the ordered startup reads, and caches repo validation commands plus definition_of_done before choosing work.
+3. Agent first reads `.agents/rpi/next-work.jsonl`, claims the highest-value harvested item, and runs `/rpi` on it.
+4. The cycle's `/post-mortem` harvests 2 new follow-up items; evolve immediately re-reads the queue instead of trusting the pre-cycle snapshot.
+5. With harvested work drained, evolve checks `bd ready` and lands the top unblocked bead.
+6. With beads drained, evolve measures GOALS.yaml, finds a directive gap, and runs `/rpi` on that goal.
+7. Once goals/directives are healthy, evolve generates testing work from thin coverage and lands the best regression-test improvement.
+8. Testing producers dry up, so evolve runs validation tightening / bug-hunt and fixes the highest-value finding.
+9. When remediation layers are empty, evolve mines hotspot/TODO/stale-doc drift and turns any real findings into durable work.
+10. If all remediation layers stay empty, evolve writes a concrete feature suggestion as durable work and starts the next `/rpi`.
+11. Only after repeated empty queue + generator passes does dormancy trigger and teardown begin.
+12. To stop earlier: create `~/.config/evolve/KILL` or `.agents/evolve/STOP`.
+
+**Result:** Runs as an always-on compounding loop. Empty queues trigger more work discovery; they do not end the run.
+
+## Dry-Run Mode
+
+**User says:** `/evolve --dry-run`
+
+**What happens:**
+1. Agent measures fitness.
+2. Agent reports the next harvested/beads/goals item it would work on.
+3. If those are empty, agent reports the next generator layer it would run (testing, validation, drift, or feature suggestion).
+4. Agent stops without executing.
+
+**Result:** Next-action preview without code changes.
+
+## Regression with Revert
+
+**User says:** `/evolve --max-cycles=3`
+
+**What happens:**
+1. Agent claims a harvested queue item in cycle 1 and starts `/rpi`.
+2. Post-cycle fitness shows a regression.
+3. Agent reverts the cycle's changes.
+4. Agent clears the queue claim and leaves `consumed: false`, so the work is available again.
+5. Agent logs the regression and continues.
+
+**Result:** Fitness regressions are auto-reverted, and claimed work is re-queued instead of being lost.
+
+## Worked Overnight Ladder
+
+**User says:** `/evolve --compile`
+
+**What happens:**
+1. Compile warmup surfaces a stale research note about runtime smoke coverage.
+2. Evolve loads the repo execution profile first, so the startup reads, tracker wrapper, and validation bundle come from repo policy instead of a giant prompt.
+3. `bd ready` has one open docs/runtime parity bead, so evolve runs that first.
+4. That bead's `/post-mortem` harvests an implementation follow-up into `next-work.jsonl`; evolve re-reads the queue and runs it immediately.
+5. The queue empties, so evolve measures goals and fixes one directive gap via `/rpi`.
+6. All goals now pass. Evolve generates testing work from thin coverage and lands a new regression test.
+7. Testing producers dry up, so evolve runs a bug-hunt / validation sweep and tightens a missing validation gate.
+8. No bug-hunt findings remain, so evolve mines complexity/TODO/stale-doc drift and queues one cleanup item.
+9. After that cleanup, the remediation ladder is empty, so evolve writes a concrete feature suggestion bead and starts the next `/rpi`.
+10. Only after harvested work, beads, goals, testing, bug hunt, drift mining, and feature suggestions all come up empty across repeated passes does dormancy trigger.
+
+**Result:** One long-running session compounds across beads -> harvested work -> goals -> testing -> bug hunt -> feature suggestion instead of stopping at the first empty queue.

+# Fitness Scoring
+
+## Measurement
+
+Run the fitness measurement script to produce a rolling snapshot:
+
+```bash
+bash scripts/evolve-measure-fitness.sh \
+  --output .agents/evolve/fitness-latest.json \
+  --timeout 60 \
+  --total-timeout 75
+```
+
+**Do NOT write per-cycle `fitness-{N}-pre.json` files.** The rolling file is sufficient for work selection and regression detection.
+
+This writes a fitness snapshot to `.agents/evolve/` atomically via a temp file plus JSON validation. The AgentOps CLI is required for fitness measurement because the wrapper shells out to `ao goals measure`. If measurement exceeds the whole-command bound or returns invalid JSON, the wrapper fails without clobbering the previous rolling snapshot.
+
+## Era Baseline Capture (First Run Only)
+
+Skip if `--skip-baseline` or `--beads-only` or baseline already exists.
+
+`/evolve` captures this automatically before entering the RPI loop. It hashes
+the active GOALS.md or GOALS.yaml file to an era ID, then writes a snapshot
+under `.agents/evolve/fitness-baselines/goals-<hash>/` if that era directory
+does not already contain a JSON snapshot.
+
+For manual recovery or one-off capture, compute the same era ID and use the
+helper script:
+
+```bash
+GOALS_FILE=""
+if [ -f GOALS.md ]; then
+  GOALS_FILE="GOALS.md"
+elif [ -f GOALS.yaml ]; then
+  GOALS_FILE="GOALS.yaml"
+fi
+
+if [ -n "$GOALS_FILE" ]; then
+  ERA_ID="goals-$(shasum -a 256 "$GOALS_FILE" | awk '{print substr($1, 1, 12)}')"
+  bash scripts/evolve-capture-baseline.sh \
+    --label "$ERA_ID" \
+    --timeout 60 \
+    --total-timeout 75
+fi
+```
+
+## Post-Cycle Re-Measurement (Regression Gate)
+
+After execution, re-measure to detect regressions:
+
+```bash
+bash scripts/evolve-measure-fitness.sh \
+  --output .agents/evolve/fitness-latest-post.json \
+  --timeout 60 \
+  --total-timeout 75 \
+  --goal "$GOAL_ID"
+
+# Extract goal counts for cycle history entry
+PASSING=$(jq '[.goals[] | select(.result=="pass")] | length' .agents/evolve/fitness-latest-post.json 2>/dev/null || echo 0)
+TOTAL=$(jq '.goals | length' .agents/evolve/fitness-latest-post.json 2>/dev/null || echo 0)
+```
+
+**If regression detected** (previously-passing goal now fails):
+
+```bash
+git revert HEAD --no-edit  # single commit
+# or for multiple commits:
+git revert --no-commit ${CYCLE_START_SHA}..HEAD && git commit -m "revert: evolve cycle ${CYCLE} regression"
+```
+
+Set outcome to "regressed".
+
+## Oscillation Detection
+
+Before working a failing goal, check if it has oscillated (improved-to-fail transitions >= 3 times in `cycle-history.jsonl`). If so, quarantine it and try the next failing goal.
+
+```bash
+# Reads cycle history via BC3 LoopReaderPort (soc-y5vh.4 wrapper),
+# not raw .agents/evolve/cycle-history.jsonl slurp.
+OSC_COUNT=$(scripts/evolve-read-cycle-history.sh recent 0 \
+  | jq -r "select(.target==\"$FAILING\") | .result" \
+  | awk 'prev=="improved" && $0=="fail" {count++} {prev=$0} END {print count+0}')
+if [ "$OSC_COUNT" -ge 3 ]; then
+  QUARANTINED_GOALS[$FAILING]=true
+  echo "{\"cycle\":${CYCLE},\"target\":\"${FAILING}\",\"result\":\"quarantined\",\"oscillations\":${OSC_COUNT},\"timestamp\":\"$(date -Iseconds)\"}" >> .agents/evolve/cycle-history.jsonl
+fi
+```
+
+See also: `references/oscillation.md` for full quarantine protocol.

+# Gate Hygiene — Pre-Gate Sync and Output Parsing
+
+Two recurring gate-stage frictions that compound across long sessions: missing source-surface rebuilds (the gate runs against stale binaries) and trusting trailing status lines (the gate output mixes blocking and advisory signals).
+
+## Pre-gate source-surface detection
+
+Before invoking `pre-push-gate.sh` (or any binary-dependent gate), inspect the staged diff and rebuild downstream artifacts if any of these surfaces changed:
+
+| Changed surface | Required pre-gate action |
+|---|---|
+| `cli/**/*.go` | `cd cli && make build && go install ./cmd/ao` — refreshes `cli/bin/ao` and `~/go/bin/ao` so the gate sees the new Go behaviour |
+| `skills/**` or `hooks/**` | `cd cli && make sync-hooks` — refreshes `cli/embedded/{skills,hooks}/` so the embedded-parity check passes |
+| `skills-codex/**` | `bash scripts/regen-codex-hashes.sh` — refreshes generated_hash values in the codex manifest |
+| `schemas/**` and `docs/contracts/**` together | re-run contract validation locally first; do not let CI surface the drift |
+
+Detection recipe:
+
+```bash
+changed=$(git diff --cached --name-only)
+echo "$changed" | grep -q '^cli/.*\.go$' && (cd cli && make build && go install ./cmd/ao)
+echo "$changed" | grep -qE '^(skills/|hooks/)' && (cd cli && make sync-hooks)
+echo "$changed" | grep -q '^skills-codex/' && bash scripts/regen-codex-hashes.sh
+```
+
+Without these pre-gate steps, the gate may fail with stale-binary or embedded-drift errors that look like real regressions but are just plumbing. Each false failure costs a turn of recovery work.
+
+## Gate output parsing
+
+The pre-push gate (and similar two-pass scripts) emits both blocking and advisory results. Trusting only the trailing status line conflates them. Use a structured grep:
+
+```bash
+# Capture full output, then parse explicit failure markers
+bash scripts/pre-push-gate.sh --fast 2>&1 | tee /tmp/gate.log
+
+# Authoritative blocking failures (case-sensitive Pass N: FAILED|BLOCKED)
+if grep -E '^.*Pass [0-9]+: (FAILED|BLOCKED)' /tmp/gate.log >/dev/null; then
+  echo "BLOCKING failure detected"
+  exit 1
+fi
+
+# Advisory issues — record but don't block
+grep -E 'advisory|warning|WARN' /tmp/gate.log || true
+```
+
+Anti-pattern: reading `tail -1 /tmp/gate.log` and treating "passed (N skipped)" as authoritative. A run can show "Pass 1: FAILED" mid-output and "passed (X skipped)" at the end if Pass 2 ran in advisory-only mode against the worktree. The structural markers (`Pass N: FAILED|BLOCKED`) are the truth.
+
+## When to use `PRE_PUSH_SKIP_EVAL=1`
+
+Documented release valve for the eval canary lane only, when:
+- The canary is flaking on pre-existing infra (filed as a tracked bead)
+- The current diff is unrelated to evals/, schemas/eval-, or cli/cmd/ao/eval
+- A recorded recent run has confirmed the canary is currently 50/50
+
+Never use `--no-verify`. The pre-commit hook is a no-op for most diffs but the principle violation is durable in `git log` and surfaces in post-mortem.
+
+## Pre-push diff-scope check (mandatory before every commit)
+
+Two cheap pre-commit reads catch the failure modes that cost a full fix-and-repush round each (the 2026-05-29 `/burndown` + codex-budget reds):
+
+1. **`git status --short` must show ALL intended files staged.** A half-staged commit — the feature gate-script left out while only its test was committed — let CI run the *old* code so the new assertion could not pass (the #612 red). A feature and its test are one commit, not the test alone.
+2. **`git diff origin/main --stat` must be SCOPE-ONLY.** Confirm: no collateral deletions (a `git checkout --theirs` conflict take silently dropped two *unrelated* skill rows in the #600 rebase), and no lossy whole-file reformats (a 252-line `catalog.json` round-trip — discard those and use the idempotent appender). For generated/narrative files, restore `origin/main`'s version and **re-run the generator** rather than hand-merging.
+
+## Triage red precisely — pre-existing-main vs your-change
+
+Not every red is yours. The `agentops` main branch carries known pre-existing failures a local gate or a broad generator will surface:
+
+- **Local `mkdocs --strict`** fails on tracked docs because the system `mkdocs` (≤1.1.2) can't parse the modern `mkdocs.yml` (needs material plugins). CI uses the venv and passes. Confirm a flagged file is `git ls-tree origin/main`-tracked AND absent from your diff → pre-existing, proceed.
+- **~7 codex `.agentops-generated.json` drifts** (deps, provenance, red-team, release, scenario, trace, using-agentops): `regen-codex-hashes.sh` "updates" them because they're drifted on main. **REVERT them** (`git checkout origin/main -- <those>`) and keep only your skill's hash; surgically rebuild the manifest from `origin/main` + your delta. The CI artifact gate is changed-files-scoped (`--scope head`) so it ignores the pre-existing drift; sweeping them in adds unrelated churn and risks a manifest↔marker mismatch.
+
+**Rule:** only fix red your own diff introduced. When a generator touches files outside your bead's scope, revert those files. "The generator changed it" never justifies shipping unrelated drift.

+## Fitness Snapshot Format
+
+Each cycle writes a fitness snapshot with **continuous values** (not just pass/fail):
+
+```json
+{
+  "cycle": 1,
+  "timestamp": "2026-02-12T15:45:00-05:00",
+  "cycle_start_sha": "abc1234",
+  "goals": [
+    {
+      "id": "go-coverage-floor",
+      "result": "pass",
+      "weight": 2,
+      "value": 86.1,
+      "threshold": 80
+    },
+    {
+      "id": "doc-coverage",
+      "result": "pass",
+      "weight": 2,
+      "value": 20,
+      "threshold": 16
+    },
+    {
+      "id": "go-cli-builds",
+      "result": "pass",
+      "weight": 5,
+      "value": null,
+      "threshold": null
+    }
+  ]
+}
+```
+
+- **value**: The continuous metric extracted from the check command (null for binary-only goals)
+- **threshold**: The pass/fail threshold (null for binary-only goals)
+- **cycle_start_sha**: Git SHA at cycle start, used for multi-commit revert on regression
+
+Pre-cycle snapshot: `fitness-latest.json` (rolling, overwritten each cycle)
+Post-cycle snapshot: `fitness-latest-post.json` (rolling, for regression comparison)
+
+## Era Baselines
+
+Before the first improvement cycle of a new goal era runs, evolve captures an
+immutable baseline snapshot under
+`.agents/evolve/fitness-baselines/goals-<hash>/`, where `<hash>` is the first
+12 hex characters of the SHA-256 digest of the active GOALS.md or GOALS.yaml
+file. A new goal era gets a new directory automatically; an existing era is
+not recaptured once that directory contains a JSON snapshot.
+
+Each era baseline includes:
+- **All goals** from GOALS.yaml or GOALS.md, measured in their initial state for that era
+- **Baseline metadata** embedded in the snapshot JSON written by `ao goals measure`
+- **No regression comparisons** — this is the starting point for that era
+
+When the session ends (at Teardown), the system computes the **session fitness trajectory** by comparing the current era baseline against the final cycle snapshot. This produces `session-fitness-delta.md`, which shows which goals improved, regressed, or stayed unchanged over the entire /evolve session.
+
+## Meta-Goals
+
+Meta-goals validate the validation system itself. Use them to prevent exception lists (allowlists, skip lists) from accumulating stale entries unnoticed.
+
+```yaml
+# Meta-goals validate the validation system itself
+goals:
+  - id: allowlist-hygiene
+    description: "Every dead-code allowlist entry should have 0 non-test callers"
+    check: "bash scripts/check-allowlist-hygiene.sh"
+    weight: 7
+
+  - id: skip-list-hygiene
+    description: "Every skip-list entry should still reference an existing test"
+    check: "bash scripts/check-skip-list-hygiene.sh"
+    weight: 5
+```
+
+**When to add a meta-goal:** After pruning any allowlist or exception list, always add a corresponding meta-goal that fails if entries have callers/references. Allowlists without meta-goals are technical debt magnets — they grow silently across epics.
+
+## Maintaining GOALS.yaml
+
+Use `/goals` to maintain the fitness specification:
+- `/goals` — run all checks, report pass/fail by pillar
+- `/goals generate` — scan repo for uncovered areas, propose new goals
+- `/goals prune` — find stale/broken goals, propose removals or updates
+
+## GOALS.md Format (Version 4)
+
+GOALS.md extends the YAML format with strategic intent:
+
+```markdown
+# Goals
+
+<Mission statement>
+
+## North Stars
+- <Aspiration>
+
+## Anti Stars
+- <What to avoid>
+
+## Directives
+
+### 1. <Title>
+<Description>
+**Steer:** increase | decrease | hold | explore
+
+## Gates
+| ID | Check | Weight | Description |
+|----|-------|--------|-------------|
+| id | `command` | N | Description |
+```
+
+### Evolve Integration
+
+When GOALS.md is detected, evolve uses the directive-based cascade (Step 3.1):
+1. `ao goals measure --directives` returns the directive list as JSON
+2. Top-priority directive (lowest number) is assessed for gaps
+3. If gap found → generates work item from directive description + steer
+4. Directive becomes the work source for the cycle
+
+When `--beads-only` is passed, directive assessment is skipped entirely.
+
+### Format Detection
+
+`ao goals measure` auto-detects format. When both GOALS.yaml and GOALS.md exist, GOALS.md takes precedence.

+# Knowledge Loop Integration
+
+## Compile Warmup (--compile only)
+
+Skip if `--compile` was not passed or if `--dry-run`.
+
+Run the mechanical half of the Compile cycle to surface fresh signal before the first evolve cycle:
+
+```bash
+mkdir -p .agents/mine .agents/defrag
+echo "Compile warmup: mining signal..."
+ao mine --since 26h --quiet 2>/dev/null || echo "(ao mine unavailable — skipping)"
+
+echo "Compile warmup: defrag sweep..."
+ao defrag --prune --dedup --quiet 2>/dev/null || echo "(ao defrag unavailable — skipping)"
+```
+
+Then read `.agents/mine/latest.json` and `.agents/defrag/latest.json` and note (in 1-2 sentences each):
+- Any **orphaned research** files that look relevant to current goals
+- Any **code hotspots** (high-CC functions with recent edits) that may be the root cause of failing goals
+- Any **duplicate learnings** merged by defrag — context on what's been cleaned up
+
+These notes inform work selection throughout the evolve session. Store them in a session variable (in-memory), not a file.
+
+## Harvested Work Selection (Step 3.1)
+
+Read `.agents/rpi/next-work.jsonl` and pick the highest-value unconsumed item for this repo. Prefer:
+- exact repo match before `*`, then legacy unscoped entries
+- already-harvested concrete implementation work before process work
+- higher severity before lower severity
+
+When evolve picks a queue item, **claim it first**:
+- set `claim_status: "in_progress"`
+- set `claimed_by: "evolve:cycle-N"`
+- set `claimed_at: "<timestamp>"`
+- keep `consumed: false` until the `/rpi` cycle and regression gate both succeed
+
+If the cycle fails, regresses, or is interrupted before success, release the claim and leave the item available for the next cycle.
+
+## Queue Finalization After Regression Gate
+
+- **success:** finalize any claimed queue item with `consumed: true`, `consumed_by`, and `consumed_at`; clear transient claim fields
+- **failure/regression:** clear `claim_status`, `claimed_by`, and `claimed_at`; keep `consumed: false`; record the release in `session-state.json`
+
+After the cycle's `/post-mortem` finishes, immediately re-read `.agents/rpi/next-work.jsonl` before selecting the next item. Never assume the queue state from before the cycle.
+
+## Teardown Learning Extraction
+
+1. Commit any staged but uncommitted `cycle-history.jsonl`:
+```bash
+if git diff --cached --name-only | grep -q cycle-history.jsonl; then
+  git commit -m "evolve: session teardown -- artifact-only cycles logged"
+fi
+```
+
+2. Run `/post-mortem "evolve session: ${CYCLE} cycles"` to harvest learnings.
+
+3. Push only if unpushed commits exist:
+```bash
+UNPUSHED=$(git log origin/main..HEAD --oneline 2>/dev/null | wc -l)
+[ "$UNPUSHED" -gt 0 ] && git push
+```
+
+4. Report summary: cycles, productive/regressed/idle counts, stop reason. Quality mode adds quality score + remaining findings.

+# Long-Loop Discipline — Disk Is Truth, Conversation Is Decorative
+
+The cross-cutting axiom that every other `/evolve` reference implements.
+When a loop runs past ~50 cycles (`/evolve`, `/loop`, `ScheduleWakeup`-driven
+cron), **every load-bearing state must live on disk, not in conversation
+context.** The conversation accumulates: skill prompts re-inject, hook
+reminders pile up, tool-result history grows. Auto-compact handles it well
+enough that correctness survives — *if and only if* the work-state was on
+disk to begin with.
+
+This doc is the principle; the implementing references are listed below.
+
+## The Axiom
+
+| State | Truth surface |
+|---|---|
+| Cycle outcome | `.agents/evolve/cycle-history.jsonl` (append-only, read at every cycle start) |
+| Hypothesis tracker | `.agents/evolve/hypotheses.jsonl` |
+| Queueable work | `bd ready` (Dolt-backed, out-of-band) |
+| Skill rules | `skills/<n>/SKILL.md` + `references/` (read fresh per cycle) |
+| Conversation context | **Decorative** — re-derives state from disk; never trusted alone |
+
+If you remove the conversation context entirely between cycles and the work
+keeps moving, the loop is healthy. If removing it breaks the loop, you are
+storing load-bearing state in the wrong place.
+
+## Evidence (anchored)
+

+
+## How To Apply
+
+1. **Read the ledger first.** Every cycle's first action is
+   `tail -n 50 .agents/evolve/cycle-history.jsonl` (or the
+   `productionLoopReader` adapter). Recover state from there, not from prior
+   turns' messages.
+2. **Append, don't overwrite.** Each cycle appends one JSONL line. Never
+   rewrite earlier cycles. The ledger is the audit trail.
+3. **Bead-driven work selection.** `bd ready` is the queue. Beads live in
+   Dolt; the conversation never owns work scheduling.
+4. **Falsify aspirational rules.** Any rule in `SKILL.md` that depends on
+   the agent following it (vs. a harness gate enforcing it) will be
+   violated within 4-6 cycles. Wire automation or accept the rule is
+   guidance only.
+5. **Treat "complete" claims with suspicion.** When a cycle says "all
+   surfaces wired," the next CI run often finds one more. Add a per-cycle
+   drift sweep instead of trusting prior claims.
+6. **Protect disk-truth in shared trees.** See
+   [../../swarm/references/shared-checkout-discipline.md](../../swarm/references/shared-checkout-discipline.md)
+   — disk-truth only survives if peer agents don't clobber it via
+   `git add -A` or destructive recovery.
+
+## Implementing References (Already In `/evolve`)
+
+The axiom is the principle. Each reference below is one mechanism that
+keeps disk-truth working:
+
+| Reference | Role |
+|---|---|
+| [cycle-history.md](cycle-history.md) | JSONL format, recovery protocol, kill switch |
+| [autonomous-execution.md](autonomous-execution.md) | ScheduleWakeup self-perpetuation pattern |
+| [context-budget.md](context-budget.md) | `CONTEXT_BUDGET_EXHAUSTED` as a third stop reason |
+| [convergence-mechanics.md](convergence-mechanics.md) | Read-path mechanisms (prior-failure injection, healing-first classifier) |
+| [scout-mode.md](scout-mode.md) | Scout-cycle as a first-class disk-truth-only result type |
+| [gate-hygiene.md](gate-hygiene.md) | Pre-gate source-surface detection + structural gate-output parsing |
+| [metronome-gate.md](metronome-gate.md) | Cross-cycle detector blocking same-mode-repeated failure |
+| [pre-flight-schema-check.md](pre-flight-schema-check.md) | Cheap field-fit check before architectural migration |

+# Mechanical Batch Work — Script vs Per-File Edit
+
+A "mechanical batch" is work where the same edit is applied to N files mechanically, with no per-file judgement after the pattern is established. Examples from prior sessions: declaring `practices: [slug]` across 533 cli/ Go files, regenerating COMMANDS.md from a Cobra tree, bumping a version literal in N manifests.
+
+The default per-file `Edit` tool path scales linearly with N and burns context. Switch to a script when ANY of these apply:
+
+- N > ~20 files
+- The transformation is **uniform** (same regex / same sed / same template field)
+- A failure on file K does not change the strategy for files K+1..N
+- Per-file output verification is cheap (`git diff --stat`, a single grep)
+
+## Script-first pattern
+
+```bash
+# 1. Inventory candidates with the predicate the task implies
+candidates=$(git ls-files 'skills/**/SKILL.md' | xargs -I{} bash -c '
+  grep -L "^practices:" "{}" >/dev/null && echo "{}"
+' | head -50)
+
+# 2. Apply the mechanical edit
+for f in $candidates; do
+  awk '
+    /^description:/ && !done { print; print "practices: [<slug>]"; done=1; next }
+    { print }
+  ' "$f" > "$f.tmp" && mv "$f.tmp" "$f"
+done
+
+# 3. Verify in one shot
+git diff --stat
+grep -c "^practices:" $candidates | sort
+```
+
+## Per-file Edit pattern (when the above does NOT apply)
+
+Use `Edit` per file only when:
+
+- The transformation requires per-file decisions (which slug? which carrier?)
+- N is small (< 10)
+- Verification benefits from reading each diff in context
+
+## Decision in Step 4
+
+When `/rpi` discovery surfaces a per-file pattern with N > 20 uniform candidates, the implementation phase should generate a script under `scripts/` or use an inline awk/sed pass rather than queuing N `Edit` operations. The post-edit gate then verifies the batch atomically.
+
+If the script needs different parameters per file, that is a signal the work isn't actually mechanical — fall back to per-file Edit and reduce N (split the cycle).
+
+## Why this matters
+
+A 533-file `practices:` backfill done via per-file Edit takes ~50× more context than the same backfill done via a script with `git diff --stat` verification. The context-budget exhausts well before the work completes, and the loop drops into a forced scout or idle state with most of the work still pending.
+
+## Anti-patterns
+
+- Running a script that mutates files but ignoring the result of `git diff` (silent partial application).
+- Using `sed -i` on a tree-traversed find without `--null` handling (filename-with-spaces breakage).
+- Mixing mechanical and per-file edits in the same commit (auditor cannot tell what was bulk-applied vs per-judged).
+- Treating a 200-file batch as a single "atomic" change — split into review-sized waves (~30-100 files) with one commit per wave.

+# Metronome Gate — Detecting Productive-Looking Repetition
+
+The work-selection ladder treats "tests passed + commit landed" as productive. That signal is necessary but not sufficient: it cannot tell apart a cycle that *applied an existing template again* from one that *closed a new lane of work*. Cycles 144-154 in this repo were 7 consecutive CLI-wiring template applications — every cycle green, every commit clean, every gate happy. Only operator override at cycle 154 stopped the run.
+
+The metronome gate adds a structural detector: when the same `mode` value repeats N times, the next rung of the ladder is forced.
+
+## State
+
+`mode_repeat_streak` is computed by `scripts/evolve-update-session-state.sh` from the trailing run of identical `mode` values in `cycle-history.jsonl`. It is derived, not authored — running the script after every cycle keeps it coherent.
+
+## Thresholds
+
+| `mode_repeat_streak` | Action |
+|---|---|
+| 0–2 | No gate. The selection ladder runs normally. |
+| 3–4 | **Soft block.** If the selected work would produce the same `mode` value, skip to the next rung of the selection ladder. Do not abort — try the rung below. |
+| 5+ | **Hard block.** Record the gap as bead/provenance evidence and require operator override (write `.agents/evolve/RESCOPE` with a new directive). The cycle is logged as `unchanged` with `selected_source: "metronome-gate-blocked"`. |
+
+## Why the threshold is 3, not 2
+
+A 2-cycle streak is normal: harvested work often comes in pairs (port + adapter, R + W, parent + child). A 3-cycle streak is the earliest signal that the *template* has become the work, not the *problem*. Stopping at 3 catches the failure mode early without blocking legitimate harvested-pair cycles.
+
+## Naming discipline (operator instruction)
+
+For the gate to work, cycle entries must use *distinguishable* `mode` values. Anti-patterns observed before this gate existed:
+
+- `template-applied-cli-wiring-5th`, `template-applied-cli-wiring-6th`, `template-applied-cli-wiring-7th` — the suffix `-Nth` made these technically unique strings but obviously the same mode. The gate canonicalizes by stripping trailing `-Nth` / `-N` patterns before comparison.
+- `wire-up-BC1`, `wire-up-BC2`, `wire-up-BC3` — the BC suffix changes but the work shape is identical. This is a *legitimate harvested-pair sequence* — three separate BCs, three real ports — and the gate correctly does NOT block here because the streak counts identical strings only. Operator distinguishes "BC-pair work" from "template metronome" by intent.
+
+When in doubt, the operator override at threshold 5+ is the safety net.
+
+## Worked example — cycles 144-154
+
+```
+cycle 144: wire-up-BC1            (streak: 1)
+cycle 145: wire-up-BC1-pair       (streak: 1, different)
+cycle 146: wire-up-complete       (streak: 1)
+cycle 147: template-applied-cli-wiring-4th  (streak: 1)
+cycle 148: template-applied-cli-wiring-5th  (streak: 2 after canonicalization)
+cycle 149: template-applied-cli-wiring-6th  (streak: 3 — SOFT BLOCK fires)
+cycle 150: template-applied-cli-wiring-7th  (streak: 4 — still blocked, next rung)
+cycle 151..154: ...                          (operator override at 154)
+```
+
+With the gate active at threshold 3, cycle 149 would have skipped to the next rung of the selection ladder, probably surfacing the latent narrowness problem 5 cycles sooner.
+
+## Interaction with idle_streak
+
+The metronome gate fires on *productive* cycles; the dormancy gate fires on *idle* cycles. They are orthogonal:
+
+- `idle_streak >= 2 AND generator_empty_streak >= 2` → dormancy (see Step 3 hard-gate)
+- `mode_repeat_streak >= 3 AND candidate.mode == last_mode` → metronome block (skip rung)
+- Both can never fire on the same cycle: idle cycles produce no work, so they cannot extend the metronome.
+
+## Why this lives in /evolve, not /rpi
+
+`/rpi` runs one cycle's worth of work. It has no visibility into prior cycles. The metronome is a *cross-cycle* pattern, only visible from the loop driver. `/evolve` is the only place that has both the ledger and the next-cycle decision.

+# New-Skill Landing — the six derived surfaces
+
+Adding or modifying a skill regenerates **six derived surfaces**, each gated by CI. Regenerating them piecemeal is the dominant fix-and-repush cause (the 2026-05-29 `/burndown` re-land needed 3 rounds; the codex-desc-budget fix needed 1). Regenerate them in **one shot** before opening the PR.
+
+## The shortcut
+
+`scripts/regen-all.sh` covers surfaces 1–3 + the CLI reference in one pass — prefer it over running the generators individually. Then run the codex + count steps below.
+
+## Live skill edits
+
+When an agent edits an existing live skill at `skills/<slug>/SKILL.md`, seal the
+edit before the next cycle hands off:
+
+```bash
+ao skills edit seal --skill <slug> --actor "${AGENT_NAME:-agent}"
+```
+
+That command stages the skill's source directory and any matching Codex skill
+directory, creates a git rollback point, and records `Skill-Edit` trailers in
+the commit body. Critical skills listed in
+`docs/contracts/critical-skills.txt` reject unattended edits; rerun with
+`--allow-critical` only for a human-supervised critical edit.
+
+Daily operator review uses:
+
+```bash
+ao skills edit digest --since "24 hours ago"
+```
+
+The digest is the lightweight immune-system surface for "what did agents teach
+the runtime today?" A live edit seal does not replace the derived-surface work
+below: new skills, renames, metadata changes, and publication-bound edits still
+need the full six-surface regeneration.
+
+## The six surfaces
+
+1. **registry.json (SKU catalog)** — `scripts/generate-registry.sh` (verify with `--check`). **The most-missed surface**: a stale `registry.json` trips `contracts-sync` ("registry.json is stale") AND `correctness(ubuntu)` ("SKU_CATALOG: DRIFT") *together*. As of ag-ekyq, `skills/skill-builder/scripts/init.sh` regenerates it automatically during scaffold; regenerate by hand for any out-of-band skill edit.
+2. **skill-domain-map** — `scripts/generate-skill-domain-map.sh` (narrative `N skills` count + per-skill row; verify `--check`).
+3. **context-map** — `scripts/generate-context-map.sh` (hex roles from frontmatter; CI gate `validate-context-map-drift`).
+4. **skill counts** — `scripts/sync-skill-counts.sh`. **The `SKILL-TIERS.md` row must be added by hand** — `sync-skill-counts` only syncs the *counts* across PRODUCT/ARCHITECTURE/SKILLS/using-agentops; it never adds the row.
+5. **codex twin** — `scripts/register-new-codex-skill.sh <name> --treatment parity_only|bespoke --reason "…"` (manifest entry + override-catalog + `.agentops-generated.json` marker, atomic + idempotent). Then **hand-author `skills-codex/<name>/prompt.md`** — codex twins are MANUAL; `regen-all.sh` does NOT generate them. Re-run `scripts/regen-codex-hashes.sh` afterward (adding `prompt.md` changes the tree hash). Parity_only minimal `prompt.md` = title + description + an `## Instructions` block ("Load and follow the sibling `SKILL.md`").
+6. **narrative skill counts** — `scripts/check-registry-drift.sh --fix-counts` (the `N skills` lines in `agentops-skill-domain-map.md` + `agentops-domain-evolution-bdd.md`).
+
+## Embedded sync
+
+If the edit touches `skills/**` content that is embedded (e.g. `using-agentops`), run `cd cli && make sync-hooks` so `cli/embedded/skills/...` stays in sync — else the `codex artifact metadata`/embedded-drift gate fails.

+# Oscillation Detection
+
+## What Is Oscillation?
+
+A goal **oscillates** when it alternates between passing and failing across
+evolve cycles. Typically this means the fix for the goal causes a side-effect
+that breaks something else, which gets reverted, which re-exposes the original
+failure — creating a loop.
+
+Example from cycle-history.jsonl:
+```
+cycle 5:  goal-X → improved
+cycle 8:  goal-X → fail
+cycle 12: goal-X → improved
+cycle 15: goal-X → fail
+```
+
+## Detection
+
+Count **improved→fail transitions** for the same `target` in
+`.agents/evolve/cycle-history.jsonl`:
+
+```bash
+# Count oscillations for a given goal — reads via BC3 LoopReaderPort
+# (soc-y5vh.4 wrapper) instead of inline JSONL slurp.
+scripts/evolve-read-cycle-history.sh recent 0 \
+  | jq -r "select(.target==\"$GOAL_ID\") | .result" \
+  | awk 'prev=="improved" && $0=="fail" {count++} {prev=$0} END {print count+0}'
+```
+
+## Threshold
+
+**3 oscillations** (improved→fail transitions) within a single session
+triggers quarantine. The goal is skipped in Step 3 selection.
+
+## Effect
+
+- Quarantined goals are skipped during work selection (Step 3)
+- Skipping a quarantined goal counts as idle (no actionable work found)
+- The quarantine is session-scoped — a new session resets the count
+- Quarantine events are logged in cycle-history.jsonl with `"result": "quarantined"`
+
+## Recovery
+
+1. Human identifies the root cause (usually a conflict between two goals)
+2. Fix the underlying issue manually
+3. Start a new evolve session (quarantine resets)
+4. Or: remove the quarantine by deleting the goal from the skip list
+
+## Why Not Just Increase the Skip Threshold?
+
+The 3-consecutive-regression skip in Step 3 only catches monotonic failure.
+Oscillation is worse — it burns cycles alternating between "fixed" and "broken"
+without the stagnation detector ever triggering (because the goal intermittently
+passes). The oscillation detector catches this pattern explicitly.

+# Parallel Goal Execution
+
+## Architecture
+
+When `--parallel` is enabled, `/evolve` uses `/swarm` to execute multiple independent
+goal improvements concurrently instead of fixing one goal per cycle.
+
+```
+/evolve --parallel (Fitness Loop)
+  │
+  ├─ Step 2: Measure ALL goals
+  │
+  ├─ Step 3: Select top N independent failing goals (max_parallel, default 3)
+  │  └─ select_parallel_goals: heuristic independence via check-script overlap
+  │
+  ├─ Step 4: Parallel execution via /swarm
+  │  ├─ TaskCreate for each selected goal
+  │  ├─ Artifact isolation: .agents/evolve/parallel-rpi/{goal.id}/
+  │  ├─ Git isolation: /swarm --worktrees (each worker in /tmp/evolve-{goal.id})
+  │  └─ /swarm spawns N fresh-context workers, each runs full /rpi cycle:
+  │     └─ research → plan → pre-mortem → crank → vibe → post-mortem
+  │
+  ├─ Step 5: Single regression gate (re-measure ALL goals after wave)
+  │  ├─ If ANY goal regressed → revert ENTIRE parallel wave
+  │  └─ If clean → log cycle with goal_ids array
+  │
+  └─ Step 6-7: Log, loop (same as sequential)
+```
+
+## The Fractal Pattern
+
+Swarm is the universal coordination primitive at every level:
+
+```
+LEVEL 0: /evolve --parallel
+  └─ /swarm (parallel goal improvements)     ← NEW: swarm at evolve level
+     └─ LEVEL 1: /rpi (per-goal lifecycle)
+        └─ research → plan → crank → vibe → post-mortem
+           └─ LEVEL 2: /crank (epic execution)
+              └─ /swarm (parallel issue implementation)  ← existing: swarm at crank level
+                 └─ LEVEL 3: workers (atomic tasks)
+```
+
+Each level creates fresh context for the next (Ralph Wiggum pattern).
+The pattern is always: **one leader + N fresh-context workers + validation + cleanup**.
+
+## Goal Independence Detection
+
+`select_parallel_goals` uses a heuristic check:
+
+1. Start with highest-weight failing goal
+2. For each remaining eligible goal (weight-sorted):
+   - Compare check commands for shared scripts/paths
+   - If independent: add to selection (up to max_parallel)
+   - If overlapping: skip (handled in next cycle)
+
+**This is a heuristic, not a guarantee.** Goals don't declare which files their
+improvements will modify — only which scripts verify them. Two goals with different
+check scripts may still modify overlapping files.
+
+**The regression gate (Step 5) is the real safety net.** If parallel goals conflict,
+the regression check detects it and reverts the entire wave. This makes false
+negatives in independence detection safe (they just cost one wasted cycle).
+
+## Artifact Isolation
+
+Each parallel /rpi worker needs isolated artifact directories to prevent collision:
+
+| Directory | Purpose | Isolation |
+|-----------|---------|-----------|
+| `.agents/evolve/parallel-rpi/{goal.id}/` | /rpi phase summaries, next-work | Per-goal subdirectory |
+| `.agents/evolve/parallel-results/{goal.id}.md` | Worker result summary | Per-goal file |
+| `/tmp/evolve-{goal.id}` | Git worktree | Per-goal worktree via /swarm |
+
+Without isolation, N concurrent /rpi cycles would collide on `.agents/rpi/`
+(phase summaries, next-work.jsonl) and git index locks.
+
+## Git Isolation
+
+Parallel workers MUST use worktree isolation (via `/swarm --worktrees`):
+
+- Each worker operates in `/tmp/evolve-{goal.id}` worktree
+- No git lock conflicts (each worktree has its own index)
+- Lead merges worktrees after all complete, before regression gate
+- On regression: revert all merged commits using `cycle_start_sha`
+
+## Regression Handling
+
+**Sequential mode:** Revert commits from one goal's /rpi cycle.
+
+**Parallel mode:** Revert ALL commits from the entire parallel wave.
+The `cycle_start_sha` (captured before the wave) anchors the revert point.
+All N goal improvements are rolled back together — even goals that individually
+succeeded. This is by design: if goals interfere, we can't know which one
+caused the regression without testing each in isolation.
+
+## Cycle History Schema
+
+Sequential cycles use `target` (string). Parallel cycles use `goal_ids` (array) with `parallel: true`:
+
+```jsonl
+{"cycle": 1, "target": "test-pass-rate", "result": "improved", "sha": "abc1234", ...}
+{"cycle": 2, "goal_ids": ["doc-coverage", "lint-clean"], "result": "improved", "sha": "def5678", "parallel": true, ...}
+```
+
+Legacy entries may use `goal_id` instead of `target` and `commit_sha` instead of `sha`. Tools should handle both.
+
+## Compounding
+
+Each parallel /rpi worker runs its own /post-mortem, which feeds the knowledge
+flywheel independently. Learnings from all N parallel cycles compound into the
+flywheel, feeding the next /evolve cycle.
+
+## When to Use
+
+| Scenario | Mode |
+|----------|------|
+| 1-2 failing goals | Sequential (default) — parallelism overhead not worth it |
+| 3+ independent failing goals | `--parallel` — significant speedup |
+| Goals with overlapping files | Sequential — parallel would cause conflicts |
+| First run on new repo | Sequential — learn the codebase before parallelizing |
+
+## Constraints
+
+- Max 5 parallel goals per wave (`--max-parallel` cap)
+- Default 3 parallel goals (balance between speedup and resource usage)
+- Each /rpi worker needs a full context window — budget accordingly
+- Worktree isolation required (no shared-worktree parallel /rpi)

+   && [ "$session_pr_count_at_last_checkpoint" -lt "${SESSION_PR_THRESHOLD:-5}" ]; then
+  # checkpoint fires once per crossing — not repeatedly at every cycle past 5
+  run_postmortem_checkpoint
+fi
+```
+
+The check is **edge-triggered** (fires when the counter first crosses the threshold), not level-triggered. After PASS/WARN, the loop continues until either another stop reason fires OR another threshold crossing — e.g., at `2 × SESSION_PR_THRESHOLD = 10`, the checkpoint re-fires for a second post-mortem.
+
+## What it MUST do
+
+1. **Invoke `/post-mortem --deep`** on the cycles since the last checkpoint (or session start). `--deep` runs 3 same-vendor judges in adversarial posture.
+
+   - Do NOT use `--mixed`. Cross-vendor (Codex availability) is an infrastructure dependency that should not block the loop gate. Reserve `--mixed` for strategic architecture decisions (e.g., the DUEL.md precedent), not per-session health checks.
+   - Do NOT use single-judge mode. Single-judge sweeps are too weak for a gate that enables continued autonomous work — the whole point of the checkpoint is adversarial counter-balance against the author who just wrote the cycles.
+
+2. **Wait for the verdict file** at `.agents/council/<date>-<scope>-postmortem/verdict.md`. The verdict file's first non-blank line must start with `## Council Verdict: <PASS|WARN|FAIL>`.
+
+3. **Branch on verdict:**
+
+   | Verdict | Action |
+   |---|---|
+   | `PASS` | Continue the ladder. Next cycle's `notes` field MUST record the verdict path. |
+   | `WARN` | Continue the ladder. Next cycle's `notes` field MUST emit the council's caveats verbatim — they need to trace through `cycle-history.jsonl` so the loop's recorded behavior reflects what was acknowledged. |
+   | `FAIL` | Write `.agents/evolve/STOP` with the verdict path embedded. Do NOT clear. Surface the council's required-follow-up list to the operator. |
+
+4. **Treat non-convergence as FAIL.** If after 600 seconds the verdict file is missing, malformed, or the council's judges disagreed irreconcilably after a second pass, default to FAIL. **Absence of evidence is NOT evidence of pass.** The 2026-05-20 failure mode was an empty 2-minute cron pass treated as council completion; this rule is the corrective.
+
+## What it MUST NOT do
+
+- **Never self-grade.** The agent who ran the cycles is the same agent doing the post-mortem. Self-attestation is definitionally invalid for the gate; council enforcement is the structural requirement.
+- **Never write `.agents/evolve/STOP` without a council verdict file.** STOP without a verdict is the 2026-05-20 anti-pattern — the file becomes a self-imposed pause that the same agent (or operator) clears without rigor. Every STOP written by this checkpoint must cite a verdict path that resolves to a FAIL verdict.
+- **Never run `/post-mortem` without `--deep` from this checkpoint.** A light-touch cron-fire pass that writes learnings but skips Phase 1 council does not satisfy the gate. The 2026-05-20 cron `/post-mortem` was insufficient by design.
+
+## Pre-creation signal (opt-in, not shipped)
+
+The pre-creation counterpart to this post-merge checkpoint — `hooks/session-pr-counter.sh` (PR #362, soc-1aou), which fired on `gh pr create` at `count >= threshold - 1` — was **removed** in the 3.0 hookless teardown (#511). AgentOps ships no hook. The reusable session-PR count it provided now lives in `scripts/session-pr-scope.sh` (the canonical `$session_pr_count` source — `scripts/session-pr-scope.sh --count`). Re-author the always-on pre-creation signal as an **opt-in** hook via the hooks-authoring skill if you want it.
+
+This checkpoint is the *post-merge* gate — it fires after PR #N+1 has merged, before cycle N+1 enters Step 1. It is **mandatory** and cannot be bypassed (the loop genuinely waits on the verdict file), unlike the advisory pre-creation signal:
+
+| Layer | Trigger | Default | Status |
+|---|---|---|---|
+| `scripts/session-pr-scope.sh` (wrap as an opt-in hook via hooks-authoring) | `gh pr create` at `count >= threshold-1` | Advisory | Reusable count; not shipped as a hook (removed in #511) |
+| `evolve` checkpoint #6 | Cycle boundary after `count >= threshold` | Mandatory | Structural council enforcement before the next cycle starts |
+
+## Configuration
+
+| Variable | Default | Effect |
+|---|---|---|
+| `SESSION_PR_THRESHOLD` | `5` | Matches soc-waxr documentation default. The 2026-05-19 session (6 PRs, 3 self-corrections) and 2026-05-20 session (5 PRs, 1 self-correction + 1 confirmation-bias verdict) are the two derivation points. Do not change without a third data point. |
+| `EVOLVE_POSTMORTEM_TIMEOUT_SEC` | `600` | Max wait for verdict file. Past this, treat as FAIL. |
+| `EVOLVE_POSTMORTEM_COUNCIL_FLAG` | `--deep` | Override only with operator sign-off in a follow-up PR; reverting to single-judge or `--mixed` requires a council justifying the change. |
+
+## Failure modes this closes
+
+The 2026-05-20 post-mortem (`.agents/council/2026-05-20-evolve-204-208-postmortem/verdict.md`) found WARN with Q4 FAIL:
+
+> The "post-mortem" that "cleared" cycle 208 was a cron-fire that wrote 5 learning files and appended a harvest entry. No Phase 1 (council) ran. No Phase 2 extraction with adversarial review. No Phase 3 backlog processing. No verdict file was produced.
+>
+> Cycle 208's notes contain the string "HEALTHY verdict from /post-mortem cron" — a verdict that does not exist in any file the council directory contains.
+
+That cycle-history entry transformed an absence (no council ran) into a positive claim (clearance exists) in an append-only ledger. Stop reason #6 prevents that pattern by requiring a real verdict file path before continuing.

+# Pre-Flight Schema Check — Stop Migration Cycles That Can't Succeed
+
+Three phase-2 port migrations attempted in cycles 156-157 of this repo all failed for the same structural reason: the port surface projected ~5 fields, the consumer read ~13 fields. The migration would have silently dropped 8+ fields the consumer relied on. The lesson is captured in `docs/learnings/2026-05-13-bc-ports-narrowness-postmortem.md`. This document encodes that lesson as a pre-cycle check.
+
+## When this gate runs
+
+Before invoking `/rpi` on a cycle whose selected work matches any of:
+
+- title contains `migrate`, `rewire`, `route through`, `port-ify`, `adapt to <Port>`
+- title contains `<Module> → <Port>Port` or similar arrow syntax
+- bd issue has label `migration` or `bc-port-adoption`
+- selected_source is `harvested` and the queue entry has `kind: "migration"`
+
+## Procedure
+
+1. **Identify the port surface.** From the work title, locate the port type definition (typically `cli/internal/ports/<port>.go`). Extract the projected struct fields.
+
+2. **Sample two consumer call sites.** From the work description, find the function or file being migrated. Grep for *its* current consumers — the call sites that depend on the data the migration will route through the port. Pick two representative ones (different files, different formatting/decision shapes).
+
+3. **Field-fit comparison.**
+   ```bash
+   PORT_FIELDS=$(grep -E '^\s+[A-Z][a-zA-Z0-9_]+\s+' cli/internal/ports/<port>.go | awk '{print $1}' | sort -u)
+   CONSUMER_FIELDS=$(grep -oE '\.[A-Z][a-zA-Z0-9_]+\b' <consumer-files> | sed 's/^\.//' | sort -u)
+   comm -23 <(echo "$CONSUMER_FIELDS") <(echo "$PORT_FIELDS")
+   ```
+   The output is the set of fields the consumer reads that the port does NOT project.
+
+4. **Decision.**
+
+   | Missing fields | Action |
+   |---|---|
+   | 0 | Migration is safe. Proceed with `/rpi`. |
+   | 1–2 | Migration with widening. Add the missing fields to the port + writer + tests in the same cycle. Mark mode `port-widen-and-migrate`. |
+   | 3+ | **Abort the migration cycle.** File a port-widening bd issue with the field list, log this cycle as `unchanged` with `selected_source: "pre-flight-schema-fail"`, return to Step 3 selection. |
+
+5. **Special case — zero-data target.** If the consumer reads a field (e.g. `Target`) that exists in the type definition but *no actual entries in the production data store have that field set*, the consumer is dead-code-in-disguise. Don't widen — investigate whether the consumer was ever wired. Log as `selected_source: "pre-flight-dead-target"`.
+
+## Why this check is cheap
+
+A migration cycle costs ~15-30 minutes of /rpi (discovery + crank + validation). The pre-flight check is two `grep` calls and one `comm` — under 30 seconds. Catching even one bad migration pays for ~50 pre-flight runs. In this repo, three cycles spent on bad migrations (156, 157, plus the soc-0pku bead) would have been caught by 90 seconds of pre-flight.
+
+## What this does NOT replace
+
+This is a *cycle-selection* gate, not a code-quality gate. Validating the actual migration code still belongs to `/rpi` → `/validate`. The pre-flight only answers "is this migration even shaped right for the current port?"
+
+## Worked example — cycle 157 (soc-0pku)
+
+Selected work: `context_assemble.go → LoopReaderPort`
+
+```
+PORT_FIELDS=Number,Mode,Result,Commit,Milestone   # 5
+CONSUMER_FIELDS=Timestamp,Cycle,Target,GoalIDs,Result,Status,Sha,CanonicalSha,LogSha,GoalsPassing,GoalsTotal,Summary,Error   # 13
+Missing: Timestamp,Target,GoalIDs,Status,Sha,CanonicalSha,LogSha,GoalsPassing,GoalsTotal,Summary,Error   # 11
+```
+
+Missing fields = 11. Threshold 3+. **Abort.** File port-widening issue: "Widen CycleEntry: +Timestamp,+Summary at minimum; full set deferred." Cycle is logged as `unchanged`, ladder advances.
+
+This is exactly what cycle 161 ended up doing reactively — adding `StartedAt` and `Title` after the migrations bounced. With pre-flight, the widening would have happened *before* burning three cycles on doomed migrations.

+# Quality Mode
+
+## When to Use
+
+Use `--quality` when:
+- Post-mortem findings are accumulating faster than they're consumed
+- All GOALS pass but `next-work.jsonl` has unconsumed high-severity items
+- You want to resolve context-hot findings from a just-completed epic
+- Running immediately after `/post-mortem` to action its findings
+
+Do NOT use `--quality` when:
+- GOALS have critical failures (build broken, tests failing)
+- No `next-work.jsonl` exists or is empty
+- You want standard fitness-driven improvement
+
+## Quality Score
+
+Simple severity-weighted score:
+
+```
+score = 100 - (high_count * 10) - (medium_count * 3)
+```
+
+Where counts are unconsumed findings remaining in next-work.jsonl.
+
+| Score | Meaning |
+|-------|---------|
+| 90-100 | Excellent — few or no findings remaining |
+| 70-89 | Good — medium-severity items remain |
+| 50-69 | Attention needed — high-severity items remain |
+| <50 | Quality debt — many high-severity findings |
+
+## Priority Cascade (Quality Mode)
+
+1. High-severity unconsumed findings → /rpi
+2. Medium-severity unconsumed findings → /rpi
+3. Open ready beads → prefer /rpi with bead context
+4. Failing GOALS.yaml goals and directive gaps → /rpi
+5. Testing improvements → /rpi
+6. Validation tightening / bug-hunt / drift mining → /rpi
+7. Feature suggestions → durable work + /rpi
+8. Nothing after repeated generator passes → dormancy fallback
+
+## Marking Findings Consumed
+
+When evolve picks a finding from next-work.jsonl, claim it first:
+- Set `claim_status: "in_progress"`
+- Set `claimed_by: "evolve-quality:cycle-N"`
+- Set `claimed_at: "<timestamp>"`
+- Keep `consumed: false` until the /rpi cycle and regression gate both succeed
+
+If the /rpi cycle fails (regression), clear the claim and leave the finding available.
+
+## Artifacts
+
+| File | Purpose |
+|------|---------|
+| `cycle-history.jsonl` | Same as standard mode + `quality_score` field |
+| `fitness-latest.json` | Same as standard mode (goals measurement) |
+| `quality-trajectory.md` | Quality score over time (written at teardown) |
+
+## Interaction with Standard Mode
+
+Quality mode and standard mode share:
+- The same cycle-history.jsonl
+- The same fitness measurement (goals are still checked)
+- The same dormancy guard (repeated empty queue + generator passes)
+- The same circuit breaker (60 minutes)
+
+They differ in work selection priority at the top of the ladder: quality mode picks findings first, then still falls through to the same producer layers before dormancy is allowed.

+# Scout Mode — First-Class Cycle Result
+
+Scout mode is a result type alongside `improved`, `regressed`, `harvested`, and `idle`. A scout cycle reads a candidate work item, validates its scope and shape, and either annotates the queue entry with a deeper plan or splits it into smaller beads — without executing the underlying work.
+
+## When to scout
+
+Use scout-mode whenever a Step 3 selection meets any of these criteria:
+
+- The work touches **> 5 files** and is **not** a mechanical batch (a single script-driven rewrite across N similar files).
+- The work introduces a **new shape**: schema field, frontmatter carrier, JSON top-level key, validator rule, contract surface, or struct field that downstream consumers will read.
+- The work is **operator-level epic work**: multiple cooperating sub-systems must change together (e.g. emitter + consumer + validator + tests + docs in one cycle).
+- The **current cycle is > 5 productive cycles into the session** and the work would extend the implementation arc rather than close it.
+
+The scope-filter step (Step 3.0 in `SKILL.md`) consults these heuristics before any work is claimed.
+
+## What a scout cycle does (soc-5qit: split-or-defer, never bail)
+
+A scout cycle is **work**, not a stop. It MUST produce exactly one of:
+
+### Path A: Split (preferred when the queue is light and the work is decomposable)
+
+1. Read the target file(s) named in the work item (no edits).
+2. Map the **current shape** at the relevant boundary (what fields exist, what callers read it, what validators enforce).
+3. Run `bd create` to decompose the candidate into 2-N child beads, each ≤5 files and single-shape:
+   ```bash
+   bd create "Slice 1 of <parent-title>: <smaller-scope>" \
+     --description="Carved from <parent-id> by scout-mode. Scope: <files/contract>" \
+     --deps discovered-from:<parent-id> -t task -p <inherit> --json
+   ```
+4. Update the parent bead with `bd update <parent-id> --notes "scout-split into: <child-ids>"`.
+5. **Re-enter Step 3** so the smallest new child OR another ready bead gets claimed THIS cycle.
+
+### Path B: Defer (preferred when the queue has other ready beads)
+
+1. Read the target file(s) briefly to confirm the scope assessment.
+2. Append a `disposition: defer:<reason>` block to the work item.
+3. **Re-enter Step 3** so the next-priority ready bead gets claimed THIS cycle. The big candidate stays available for a future session with lighter context.
+
+### Path C: Park (operator-level epic, no obvious split)
+
+1. `bd update <id> --status blocked --notes "scope-too-big: <why>; needs operator triage"`.
+2. **Re-enter Step 3** for the next ready bead.
+
+A scout cycle does NOT:
+
+- Run `/rpi` against the original too-big candidate.
+- Edit any source file outside `.agents/rpi/next-work.jsonl` and bd metadata.
+- Commit code (bd updates land in Dolt automatically).
+- **Exit the loop** — if `bd ready` returns ≥1 unblocked bead, the cycle MUST claim and work one of them after the scout decision. (soc-5qit invariant.)
+
+## Logging a scout cycle
+
+Append to `cycle-history.jsonl` with:
+
+```json
+{"cycle": N, "result": "scout", "selected_source": "<source>", "work_ref": "<id>",
+ "net_change": 0, "commit": null,
+ "milestone": "Scouted <work>; recommendation: <split|park|smaller-slice>"}
+```
+
+The `result: scout` value is canonical alongside `improved | regressed | harvested | idle | unchanged`.
+
+## Daily learning capture
+
+Scout cycles still get a micro-capture line. Use the form:
+
+```
+- cycle N [scout] <work-ref>: <what was learned about the shape>  INSIGHT: <tag>
+```
+
+## Promotion path
+
+When a scouted item later becomes single-cycle-doable (because earlier prerequisites landed), drop the `disposition` block and let normal Step 3.1 selection pick it up.
+
+## Why scout is not "idle"
+
+`idle` means "no actionable work in any layer". Scout means "actionable work found but the shape is wrong for this cycle's budget". These are structurally different stop reasons. Conflating them masks the real failure mode: the loop has work but can't safely run it.

+# Snapshot Pattern For Long-Cycle Gates
+
+Gates that depend on **multi-session corpus state** (flywheel
+compounding, corpus freshness, knowledge-registry health, AOP-claim
+coverage) cannot be evaluated by a single CI run on a greenfield
+checkout — the corpus isn't there. The 4-step **snapshot pattern**
+converts these into single-commit-validatable artifacts: the live gate
+computes the metric on demand, the operator snapshots it to a
+git-tracked JSON file with a staleness window, and the CI gate
+validates the snapshot file rather than re-running the live metric.
+
+This is how disk-is-truth (see long-loop-discipline (disk-is-truth axiom))
+extends into CI: the **disk file is the gate's truth surface**, and
+the live metric only refreshes it.
+
+## The 4-Step Pattern
+
+### 1. Live Gate (Operator-Local)
+
+A script that computes the multi-session metric on demand. Runs in
+the operator's full corpus, not in CI.
+
+```bash
+# Example: live gate for flywheel compounding
+bash scripts/check-flywheel-compounding.sh
+# Internally: ao flywheel status → exits 0 if compounding, 1 if not
+```
+
+### 2. Snapshot Command (Operator Cadence)
+
+Wraps the live result in a JSON envelope with `recorded_at`,
+`git_sha`, and the metric payload. Writes to a git-tracked path.
+
+```bash
+# Example: snapshot the live result
+bash scripts/snapshot-flywheel-compounding.sh
+# Writes docs/releases/flywheel-compounding-snapshot.json
+```
+
+The snapshot file is **the durable proof**. Operator runs the
+snapshot script on cadence (e.g., before each release, or weekly).
+
+### 3. CI Gate (Snapshot Validation)
+
+CI does **not** re-run the live metric (it can't — no corpus). It
+validates the snapshot file:
+
+- Structural shape (required keys present)
+- Staleness threshold (e.g., < 14 days old)
+- Asserted value (`compounding == true`, `freshness_score >= N`)
+
+```bash
+# Example: CI gate validates the snapshot
+bash scripts/check-flywheel-compounding-snapshot.sh
+# Fails if snapshot missing | > 14 days old | shows metric flipped
+```
+
+### 4. Wire As A Regular Gate
+
+- `GOALS.md` row naming the metric
+- `.github/workflows/validate.yml` CI job
+- `scripts/pre-push-gate.sh` lane invocation
+- `AGENTS.md` "CI Jobs and What They Check" row
+- (per the parity-surface inventory — see
+  `docs/learnings/2026-05-12-parity-surface-inventory-grew-from-4-to-7-across-cycles-64-70.md`)
+
+Once wired, the snapshot pattern looks like a regular gate; the
+operator-cadence-refresh is the only non-standard piece.
+
+## Why This Matters
+
+Without this pattern, long-cycle gates stay in the Roadmap column
+forever because **CI can't run them green** — a clean CI runner has
+no corpus, no flywheel history, no AOP-claim accumulation. Three
+GOALS.md gates closed in one /evolve session because of this pattern
+(G1 flywheel-snapshot, D11 corpus-freshness, D10 workbench-delta).
+
+The pattern is the implementation of long-loop-discipline (disk-is-truth axiom)
+at the CI layer: the disk file is the load-bearing state, the live
+metric is the refresh path, and CI consumes the disk.
+
+## Evidence (anchored)
+
+> "Gates that depend on multi-session corpus state (e.g., flywheel
+> compounding, corpus freshness, knowledge registry health) cannot be
+> evaluated by a single CI run on a greenfield checkout — the corpus
+> isn't there. … The snapshot file is the durable proof. The CI gate
+> ensures the operator refreshes it on cadence. Each surface is
+> testable on a clean CI runner without N sessions of warmup."
+— `.agents/learnings/2026-05-11-quick-snapshot-pattern-for-long-cycle-gates.md`
+(retro-quick, validate phase)
+
+> "Applications validated this session: corpus snapshot (D11, cycle
+> 22), flywheel compounding (G1, cycle 24), workbench delta (D10,
+> cycle 26), README claim manifest (PG4, cycle 30), AOP-CLAIM
+> all-claims map (cycle 35). The structural-floor contract gate
+> (cycle 41) is the generalization — same pattern at the corpus level."
+— same source
+
+## How To Apply (When Adding A New Long-Cycle Gate)
+
+1. **Identify the metric.** Does it need a corpus, history, or
+   multi-session state to compute? If yes, snapshot pattern. If no, a
+   regular CI gate suffices.
+
+2. **Write the live gate** under `scripts/check-<metric>.sh`. Exit 0
+   on success, non-zero on regression. This runs in the operator's
+   environment.
+
+3. **Write the snapshot command** under `scripts/snapshot-<metric>.sh`.
+   Output JSON to a git-tracked path:
+   ```json
+   {
+     "recorded_at": "2026-05-18T19:42:00Z",
+     "git_sha": "abc1234",
+     "metric_name": "flywheel_compounding",
+     "value": true,
+     "details": { /* metric-specific payload */ }
+   }
+   ```
+
+4. **Write the snapshot validator** under
+   `scripts/check-<metric>-snapshot.sh`. Read the JSON, assert shape +
+   staleness + value.
+
+5. **Wire all 7 parity surfaces** per the parity-surface inventory:
+   pre-push lane, validate.yml job, summary.needs[], summary echo,
+   AGENTS.md row, registry.json (if a new hook), bats stub (if pre-push).
+
+6. **Set a refresh cadence.** Document in `AGENTS.md` or `GOALS.md`
+   when the operator runs the snapshot script (before release,
+   weekly, before-each-evolve-session).
+
+## Failure Modes
+
+- **Skipping step 4 (snapshot validator).** Without the validator,
+  the snapshot file drifts undetected — operators stop refreshing it,
+  and CI claims green forever. The validator forces the cadence.
+- **Snapshot in chat / ephemeral state.** The snapshot MUST be
+  git-tracked. A snapshot in a session JSONL is invisible to CI.
+- **Staleness window too long.** > 30 days means the gate
+  effectively never fails. Tighten to 7-14 days.
+- **Live gate and snapshot validator disagree on shape.** Schema
+  drift between the two scripts; CI passes but the metric is wrong.
+  Lock the JSON shape in the snapshot command's documentation.
+
+## Applications (Empirical Reference)
+
+The pattern shipped 6 times across cycles 22-41 of the 2026-05-11
+evolution-roadmap drain:
+
+| Cycle | Metric | Snapshot path |
+|---|---|---|
+| 22 (D11) | corpus freshness | `docs/releases/corpus-snapshot.json` |
+| 24 (G1) | flywheel compounding | `docs/releases/flywheel-compounding-snapshot.json` |
+| 26 (D10) | workbench delta | `docs/releases/workbench-delta-snapshot.json` |
+| 30 (PG4) | README claim manifest | `docs/releases/readme-claim-manifest.json` |
+| 35 | AOP-CLAIM all-claims map | `docs/releases/aop-claims-all-snapshot.json` |
+| 41 | structural-floor contract gate (the generalization) | per-contract snapshot |
+
+Reuse-rate after first ship: 5 reuses in 19 cycles. The pattern is
+durable.

+# /evolve — Work-Selection Ladder (Step 3, full procedure)
+
+> Extracted from `skills/evolve/SKILL.md` Step 3 to keep the skill under the 10000-token ceiling (soc-opq5). SKILL.md keeps the summary + this pointer; this file owns the full per-rung procedure, code blocks, quality cascade, and dormancy hard-gate.
+
+Selection is a ladder, not a one-shot check. After every productive cycle, return to the TOP of this step and re-read the queue before considering dormancy.
+
+**Programmatic recommendation (soc-g2qd wire):** when present, consult the ladder primitive first and prefer its `.recommended_bead`; the rungs below are the cross-check + fallback.
+
+```bash
+ao loop next-work --help >/dev/null 2>&1 && RECO_BEAD=$(ao loop next-work --json 2>/dev/null | jq -r '.recommended_bead // empty')
+```
+
+When a repo-local program contract exists, apply a scope filter before Step 4:
+- candidate work that clearly requires immutable-scope edits is not eligible for direct execution
+- prefer harvested, beads, goals, and generated work that can plausibly land within mutable scope
+- if the selected item is inherently out of scope, escalate it or convert it into durable follow-up work instead of invoking `/rpi` and hoping discovery widens scope
+
+**Step 3.0: Scope filter — split-or-defer, never bail (soc-5qit)**
+
+Before claiming a candidate, gate scope vs session budget. If the work touches > 5 non-uniform files, introduces a new shape (schema field, validator, contract surface), is operator-level epic work, OR `PRODUCTIVE_THIS_SESSION > 5` and would extend an arc rather than close one — route to **scout-mode**, which MUST produce one of:
+
+1. **Split** — `bd create` 2-N child beads (each ≤5 files, single-shape) with `--deps discovered-from:<parent-id>`, annotate parent, then **re-enter Step 3** so the smallest child (or another ready bead) gets claimed THIS cycle.
+2. **Defer** — annotate the candidate with `defer:<reason>` and re-enter Step 3 so the next-priority ready bead gets claimed.
+3. **Park** (rare) — `bd update <id> --status blocked --notes "scope-too-big"` and re-enter Step 3.
+
+Scout NEVER returns "no work done." If `bd ready` ≥1, the loop MUST claim one this cycle. See `references/scout-mode.md` and `references/mechanical-batches.md`.
+
+**Metronome gate:** read `mode_repeat_streak` from `session-state.json`. If `>= 3` AND the candidate would repeat the trailing run's `mode`, BLOCK this rung and jump to the next. If `>= 5`, record the gap as bead/provenance evidence and require operator override. See `references/metronome-gate.md`.
+
+**Step 3.1: Harvested work first**
+
+Read `.agents/rpi/next-work.jsonl` and pick the highest-value unconsumed item. Prefer exact repo match, then concrete implementation work, then higher severity. Read `references/knowledge-loop-integration.md` for the claim/release protocol.
+
+**Step 3.2: Open ready beads**
+
+If no harvested item is ready, check `bd ready`. Pick the highest-priority unblocked issue.
+
+**Step 3.3: Failing goals and directive gaps** (skip if `--beads-only`)
+
+First assess directives, then goals:
+- top-priority directive gap from `ao goals measure --directives`
+- highest-weight failing goals (skip quarantined oscillators)
+- lower-weight failing goals
+
+This step exists even when all queued work is empty. Goals are the third source, not the stop condition.
+
+```bash
+DIRECTIVES=$(ao goals measure --directives 2>/dev/null)
+FAILING=$(jq -r '.goals[] | select(.result=="fail") | .id' .agents/evolve/fitness-latest.json | head -1)
+```
+
+**Oscillation check:** Before working a failing goal, check if it has oscillated (improved-to-fail transitions >= 3 times). If so, quarantine it and try the next goal. See `references/oscillation.md` and `references/fitness-scoring.md` for the detection procedure.
+
+**Duplicate-work guard (mandatory before every generator `bd create`).** The
+generators below (3.4–3.7) and the Step-4 Split rung all create beads. A stale
+phase-1 handoff repeatedly re-seeded beads for work already covered by an
+existing bead or merged PR (ag-b8m≈ag-jov, ag-6kw≈ag-c2i — ag-6jt). Before
+`bd create`, run the guard; skip creation when it reports a duplicate:
+
+```bash
+skills/evolve/scripts/duplicate-work-guard.sh "<candidate title>" || {
+  echo "skip: existing work already covers this surface"; }
+# exit 1 + "DUPLICATE: <id> [<status>] <title>" → an open/closed bead already
+# covers it (exact title OR significant-token overlap). exit 0 → safe to create.
+```
+
+This complements the loop's origin/main fast-forward: the cron runs
+`skills/evolve/scripts/sync-main-to-origin.sh` before discovery (wired into
+`scripts/overnight-evolve.sh`), which fetches origin and fast-forwards local
+`main` to `origin/main` so discovery diffs candidate slices against the true
+merge base — already-merged work reports as done, not re-seen (ag-6jt). Run it
+manually in any rpi worktree whose local `main` may be stale:
+
+```bash
+skills/evolve/scripts/sync-main-to-origin.sh
+# → "DIFF_BASE: origin/main <sha>" — diff slices against THIS, not local main.
+```
+
+**Step 3.4: Testing improvements**
+
+When queues and goals are empty, generate concrete testing work via `/test`:
+
+```
+if --no-lifecycle is NOT set:
+  Skill(skill="test", args="coverage")
+  Only files with < 40% coverage become queue items (severity threshold).
+```
+
+If `/test` is unavailable or `--no-lifecycle` is set, fall back to manual scanning:
+- find packages/files with thin or missing tests
+- look for missing regression tests around recent bug-fix paths
+- identify flaky or absent headless/runtime smokes
+
+Convert any real finding into durable work:
+- add a bead when the work needs tracked backlog ownership, or
+- append a queue item under the shared next-work contract when it should flow directly back into `/rpi`
+
+**Step 3.5: Validation tightening and bug-hunt passes**
+
+If testing improvement generation returns nothing, run lifecycle generators then bug-hunt sweeps:
+
+```
+if --no-lifecycle is NOT set:
+  a) Skill(skill="deps", args="audit")
+     Only deps with CVSS >= 7.0 or 2+ major versions behind become queue items.
+
+  b) if perf-sensitive code detected (benchmarks exist, hot path patterns):
+       Skill(skill="perf", args="profile --quick")
+       Convert significant perf findings to queue items.
+```
+
+If lifecycle generators return nothing or are skipped, fall back to manual sweeps:
+- missing validation gates
+- weak lint/contract coverage
+- bug-hunt style audits for risky areas
+- stale assumptions between docs, contracts, and runtime truth
+
+Again: convert findings into beads or queue items, then immediately select the highest-priority result and continue.
+
+**Step 3.6: Drift / hotspot / dead-code mining**
+
+If the prior generators are empty, mine for complexity debt via `/refactor`:
+
+```
+if --no-lifecycle is NOT set:
+  Skill(skill="refactor", args="--sweep all --dry-run")
+  Only functions with CC > 20 become queue items (severity threshold).
+```
+
+If `/refactor` is unavailable or `--no-lifecycle` is set, fall back to manual mining:
+- complexity hotspots
+- stale TODO/FIXME markers
+- dead code
+- stale docs
+- stale research
+- drift between generated artifacts and source-of-truth files
+
+Do not stop here. Normalize findings into tracked work and continue.
+
+**Step 3.7: Feature suggestions**
+
+If all concrete remediation layers are empty, propose one or more specific feature ideas grounded in the repo purpose, write them as durable work, and continue:
+- create a bead when the feature needs review/backlog treatment
+- or append a queue item with `source: "feature-suggestion"` when it is ready for the next `/rpi` cycle
+
+**Quality mode (`--quality`)** — inverted cascade (findings before directives):
+
+Step 3.0q: Unconsumed high-severity post-mortem findings:
+```bash
+HIGH=$(jq -r 'select(.consumed==false) | .items[] | select(.severity=="high") | .title' \
+  .agents/rpi/next-work.jsonl 2>/dev/null | head -1)
+```
+
+Step 3.1q: Unconsumed medium-severity findings.
+
+Step 3.2q: Open ready beads.
+
+Step 3.3q: Emergency gates (weight >= 5) and top directive gaps.
+
+Step 3.4q: Testing improvements.
+
+Step 3.5q: Validation tightening / bug-hunt / drift mining.
+
+Step 3.6q: Feature suggestions.
+
+This inverts the standard cascade only at the top of the ladder: findings BEFORE goals and directives. It does NOT skip the generator layers.
+
+When evolve picks a finding, claim it first in next-work.jsonl:
+- Set `claim_status: "in_progress"`, `claimed_by: "evolve-quality:cycle-N"`, `claimed_at: "<timestamp>"`
+- Set `consumed: true` only after the /rpi cycle and regression gate succeed
+- If the /rpi cycle fails (regression), clear the claim and leave `consumed: false`
+
+See `references/quality-mode.md` for scoring and full details.
+
+**Nothing found?** HARD GATE — dormancy only when ALL sources empty (soc-5qit):
+
+```bash
+READY_BEADS=$(bd ready --json 2>/dev/null | jq -r 'length // 0' 2>/dev/null || echo 0)
+HARVESTED=$(jq -r 'select(.consumed==false) | .severity' .agents/rpi/next-work.jsonl 2>/dev/null | wc -l | tr -d ' ')
+FAILING_GOALS=$(jq -r '.goals[] | select(.result=="fail") | .id' .agents/evolve/fitness-latest.json 2>/dev/null | wc -l | tr -d ' ')
+IDLE_STREAK=$(jq -r '.idle_streak // 0' .agents/evolve/session-state.json 2>/dev/null)
+
+if [ "$READY_BEADS" -gt 0 ] || [ "$HARVESTED" -gt 0 ] || [ "$FAILING_GOALS" -gt 0 ]; then
+  continue  # work exists — loop back to Step 3 (agile invariant)
+fi
+if [ "${GENERATOR_EMPTY_STREAK:-0}" -ge 2 ] && [ "${IDLE_STREAK:-0}" -ge 2 ]; then
+  REASON="stagnation: all sources empty x3"
+  # soc-g2qd wire: under loop, write-stop-marker refuses → log blocked + operator-wait, never self-halt (ADR-0007).
+  if ao loop write-stop-marker --help >/dev/null 2>&1; then
+    ao loop write-stop-marker --marker dormant --reason "$REASON" --mode loop 2>/dev/null \
+      || ao loop blocked --reason "$REASON" --needed-context "queue empty; operator adds work or marker" 2>/dev/null || true
+  else
+    printf '%s\n%s\n%s\n' "cycle $CYCLE" "$(date -u +%FT%TZ)" "$REASON" > .agents/evolve/DORMANT  # fallback
+  fi
+fi
+```
+
+**Agile invariant (soc-5qit):** `bd ready ≥ 1` ⇒ loop NEVER writes DORMANT, NEVER exits. The only path to DORMANT is fully empty backlog + dry generators. Context exhaustion → HANDOFF, not DORMANT.
+
+If work layers were empty but generators haven't exhausted 3 passes yet, persist `GENERATOR_EMPTY_STREAK` and loop back to Step 1.
+
+A cycle is idle only if NO work source returned actionable work and every generator layer also came up empty. A cycle that targeted an oscillating goal and skipped it counts as idle only after the remaining ladder was exhausted.
+
+If `--dry-run`: report what would be worked on and go to Teardown.

+description: Implement tasks from an OpenSpec change (Experimental)

+---
+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+description: Archive a completed change in the experimental workflow
+category: Workflow
+tags: [workflow, archive, experimental]
+---
+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+name: "OPSX: Bulk Archive"
+description: Archive multiple completed changes at once
+category: Workflow
+tags: [workflow, archive, experimental, bulk]
+---
+
+Archive multiple completed changes in a single operation.
+
+This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
+
+**Input**: None required (prompts for selection)
+
+**Steps**
+
+1. **Get active changes**
+
+   Run `openspec list --json` to get all active changes.
+
+   If no active changes exist, inform user and stop.
+
+2. **Prompt for change selection**
+
+   Use **AskUserQuestion tool** with multi-select to let user choose changes:
+   - Show each change with its schema
+   - Include an option for "All changes"
+   - Allow any number of selections (1+ works, 2+ is the typical use case)
+
+   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
+
+3. **Batch validation - gather status for all selected changes**
+
+   For each selected change, collect:
+
+   a. **Artifact status** - Run `openspec status --change "<name>" --json`
+      - Parse `schemaName` and `artifacts` list
+      - Note which artifacts are `done` vs other states
+
+   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
+      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
+      - If no tasks file exists, note as "No tasks"
+
+   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
+      - List which capability specs exist
+      - For each, extract requirement names (lines matching `### Requirement: <name>`)
+
+4. **Detect spec conflicts**
+
+   Build a map of `capability -> [changes that touch it]`:
+
+   ```
+   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
+   api  -> [change-c]            <- OK (only 1 change)
+   ```
+
+   A conflict exists when 2+ selected changes have delta specs for the same capability.
+
+5. **Resolve conflicts agentically**
+
+   **For each conflict**, investigate the codebase:
+
+   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
+
+   b. **Search the codebase** for implementation evidence:
+      - Look for code implementing requirements from each delta spec
+      - Check for related files, functions, or tests
+
+   c. **Determine resolution**:
+      - If only one change is actually implemented -> sync that one's specs
+      - If both implemented -> apply in chronological order (older first, newer overwrites)
+      - If neither implemented -> skip spec sync, warn user
+
+   d. **Record resolution** for each conflict:
+      - Which change's specs to apply
+      - In what order (if both)
+      - Rationale (what was found in codebase)
+
+6. **Show consolidated status table**
+
+   Display a table summarizing all changes:
+
+   ```
+   | Change              | Artifacts | Tasks | Specs   | Conflicts | Status |
+   |---------------------|-----------|-------|---------|-----------|--------|
+   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
+   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
+   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
+   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
+   ```
+
+   For conflicts, show the resolution:
+   ```
+   * Conflict resolution:
+     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
+   ```
+
+   For incomplete changes, show warnings:
+   ```
+   Warnings:
+   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
+   ```
+
+7. **Confirm batch operation**
+
+   Use **AskUserQuestion tool** with a single confirmation:
+
+   - "Archive N changes?" with options based on status
+   - Options might include:
+     - "Archive all N changes"
+     - "Archive only N ready changes (skip incomplete)"
+     - "Cancel"
+
+   If there are incomplete changes, make clear they'll be archived with warnings.
+
+8. **Execute archive for each confirmed change**
+
+   Process changes in the determined order (respecting conflict resolution):
+
+   a. **Sync specs** if delta specs exist:
+      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
+      - For conflicts, apply in resolved order
+      - Track if sync was done
+
+   b. **Perform the archive**:
+      ```bash
+      mkdir -p openspec/changes/archive
+      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+      ```
+
+   c. **Track outcome** for each change:
+      - Success: archived successfully
+      - Failed: error during archive (record error)
+      - Skipped: user chose not to archive (if applicable)
+
+9. **Display summary**
+
+   Show final results:
+
+   ```
+   ## Bulk Archive Complete
+
+   Archived 3 changes:
+   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
+   - project-config -> archive/2026-01-19-project-config/
+   - add-oauth -> archive/2026-01-19-add-oauth/
+
+   Skipped 1 change:
+   - add-verify-skill (user chose not to archive incomplete)
+
+   Spec sync summary:
+   - 4 delta specs synced to main specs
+   - 1 conflict resolved (auth: applied both in chronological order)
+   ```
+
+   If any failures:
+   ```
+   Failed 1 change:
+   - some-change: Archive directory already exists
+   ```
+
+**Conflict Resolution Examples**
+
+Example 1: Only one implemented
+```
+Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
+
+Checking add-oauth:
+- Delta adds "OAuth Provider Integration" requirement
+- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
+
+Checking add-jwt:
+- Delta adds "JWT Token Handling" requirement
+- Searching codebase... no JWT implementation found
+
+Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
+```
+
+Example 2: Both implemented
+```
+Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
+
+Checking add-rest-api (created 2026-01-10):
+- Delta adds "REST Endpoints" requirement
+- Searching codebase... found src/api/rest.ts
+
+Checking add-graphql (created 2026-01-15):
+- Delta adds "GraphQL Schema" requirement
+- Searching codebase... found src/api/graphql.ts
+
+Resolution: Both implemented. Will apply add-rest-api specs first,
+then add-graphql specs (chronological order, newer takes precedence).
+```
+
+**Output On Success**
+
+```
+## Bulk Archive Complete
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+- <change-2> -> archive/YYYY-MM-DD-<change-2>/
+
+Spec sync summary:
+- N delta specs synced to main specs
+- No conflicts (or: M conflicts resolved)
+```
+
+**Output On Partial Success**
+
+```
+## Bulk Archive Complete (partial)
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+
+Skipped M changes:
+- <change-2> (user chose not to archive incomplete)
+
+Failed K changes:
+- <change-3>: Archive directory already exists
+```
+
+**Output When No Changes**
+
+```
+## No Changes to Archive
+
+No active changes found. Create a new change to get started.
+```
+
+**Guardrails**
+- Allow any number of changes (1+ is fine, 2+ is the typical use case)
+- Always prompt for selection, never auto-select
+- Detect spec conflicts early and resolve by checking codebase
+- When both changes are implemented, apply specs in chronological order
+- Skip spec sync only when implementation is missing (warn user)
+- Show clear per-change status before confirming
+- Use single confirmation for entire batch
+- Track and report all outcomes (success/skip/fail)
+- Preserve .openspec.yaml when moving to archive
+- Archive directory target uses current date: YYYY-MM-DD-<name>
+- If archive target exists, fail that change but continue with others

+category: Workflow

+---
+
+Continue working on a change by creating the next artifact.
+
+**Input**: Optionally specify a change name after `/opsx:continue` (e.g., `/opsx:continue add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
+
+   Present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Schema (from `schema` field if present, otherwise "spec-driven")
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check current status**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
+   - `isComplete`: Boolean indicating if all artifacts are complete
+
+3. **Act based on status**:
+
+   ---
+
+   **If all artifacts are complete (`isComplete: true`)**:
+   - Congratulate the user
+   - Show final status including the schema used
+   - Suggest: "All artifacts created! You can now implement this change with `/opsx:apply` or archive it with `/opsx:archive`."
+   - STOP
+
+   ---
+
+   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
+   - Pick the FIRST artifact with `status: "ready"` from the status output
+   - Get its instructions:
+     ```bash
+     openspec instructions <artifact-id> --change "<name>" --json
+     ```
+   - Parse the JSON. The key fields are:
+     - `context`: Project background (constraints for you - do NOT include in output)
+     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+     - `template`: The structure to use for your output file
+     - `instruction`: Schema-specific guidance
+     - `outputPath`: Where to write the artifact
+     - `dependencies`: Completed artifacts to read for context
+   - **Create the artifact file**:
+     - Read any completed dependency files for context
+     - Use `template` as the structure - fill in its sections
+     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
+     - Write to the output path specified in instructions
+   - Show what was created and what's now unlocked
+   - STOP after creating ONE artifact
+
+   ---
+
+   **If no artifacts are ready (all blocked)**:
+   - This shouldn't happen with a valid schema
+   - Show status and suggest checking for issues
+
+4. **After creating an artifact, show progress**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After each invocation, show:
+- Which artifact was created
+- Schema workflow being used
+- Current progress (N/M complete)
+- What artifacts are now unlocked
+- Prompt: "Run `/opsx:continue` to create the next artifact"
+
+**Artifact Creation Guidelines**
+
+The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
+
+Common artifact patterns:
+
+**spec-driven schema** (proposal → specs → design → tasks):
+- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
+  - The Capabilities section is critical - each capability listed will need a spec file.
+- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
+- **design.md**: Document technical decisions, architecture, and implementation approach.
+- **tasks.md**: Break down implementation into checkboxed tasks.
+
+For other schemas, follow the `instruction` field from the CLI output.
+
+**Guardrails**
+- Create ONE artifact per invocation
+- Always read dependency artifacts before creating a new one
+- Never skip artifacts or create out of order
+- If context is unclear, ask the user before creating
+- Verify the artifact file exists after writing before marking progress
+- Use the schema's artifact sequence, don't assume specific artifact names
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output

+name: "OPSX: Explore"
+description: "Enter explore mode - think through ideas, investigate problems, clarify requirements"
+category: Workflow
+tags: [workflow, explore, experimental, thinking]
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+description: Create a change and generate all artifacts needed for implementation in one go
+category: Workflow
+tags: [workflow, artifacts, experimental]
+---
+
+Fast-forward through artifact creation - generate everything needed to start implementation.
+
+**Input**: The argument after `/opsx:ff` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "✓ Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+description: Start a new change using the experimental artifact workflow (OPSX)
+category: Workflow
+tags: [workflow, artifacts, experimental]
+---
+
+Start a new change using the experimental artifact-driven approach.
+
+**Input**: The argument after `/opsx:new` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Determine the workflow schema**
+
+   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user mentions:**
+   - A specific schema name → use `--schema <name>`
+   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
+
+   **Otherwise**: Omit `--schema` to use the default.
+
+3. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   Add `--schema <name>` only if the user requested a specific workflow.
+   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
+
+4. **Show the artifact status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+   This shows which artifacts need to be created and which are ready (dependencies satisfied).
+
+5. **Get instructions for the first artifact**
+   The first artifact depends on the schema. Check the status output to find the first artifact with status "ready".
+   ```bash
+   openspec instructions <first-artifact-id> --change "<name>"
+   ```
+   This outputs the template and context for creating the first artifact.
+
+6. **STOP and wait for user direction**
+
+**Output**
+
+After completing the steps, summarize:
+- Change name and location
+- Schema/workflow being used and its artifact sequence
+- Current status (0/N artifacts complete)
+- The template for the first artifact
+- Prompt: "Ready to create the first artifact? Run `/opsx:continue` or just describe what this change is about and I'll draft it."
+
+**Guardrails**
+- Do NOT create any artifacts yet - just show the instructions
+- Do NOT advance beyond showing the first artifact template
+- If the name is invalid (not kebab-case), ask for a valid name
+- If a change with that name already exists, suggest using `/opsx:continue` instead
+- Pass --schema if using a non-default workflow

+description: Guided onboarding - walk through a complete OpenSpec workflow cycle with narration
+category: Workflow
+tags: [workflow, onboarding, tutorial, learning]
+---
+
+Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
+
+---
+
+## Preflight
+
+Before starting, check if the OpenSpec CLI is installed:
+
+```bash
+# Unix/macOS
+openspec --version 2>&1 || echo "CLI_NOT_INSTALLED"
+# Windows (PowerShell)
+# if (Get-Command openspec -ErrorAction SilentlyContinue) { openspec --version } else { echo "CLI_NOT_INSTALLED" }
+```
+
+**If CLI not installed:**
+> OpenSpec CLI is not installed. Install it first, then come back to `/opsx:onboard`.
+
+Stop here if not installed.
+
+---
+
+## Phase 1: Welcome
+
+Display:
+
+```
+## Welcome to OpenSpec!
+
+I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
+
+**What we'll do:**
+1. Pick a small, real task in your codebase
+2. Explore the problem briefly
+3. Create a change (the container for our work)
+4. Build the artifacts: proposal → specs → design → tasks
+5. Implement the tasks
+6. Archive the completed change
+
+**Time:** ~15-20 minutes
+
+Let's start by finding something to work on.
+```
+
+---
+
+## Phase 2: Task Selection
+
+### Codebase Analysis
+
+Scan the codebase for small improvement opportunities. Look for:
+
+1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
+2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
+3. **Functions without tests** - Cross-reference `src/` with test directories
+4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
+5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
+6. **Missing validation** - User input handlers without validation
+
+Also check recent git activity:
+```bash
+# Unix/macOS
+git log --oneline -10 2>/dev/null || echo "No git history"
+# Windows (PowerShell)
+# git log --oneline -10 2>$null; if ($LASTEXITCODE -ne 0) { echo "No git history" }
+```
+
+### Present Suggestions
+
+From your analysis, present 3-4 specific suggestions:
+
+```
+## Task Suggestions
+
+Based on scanning your codebase, here are some good starter tasks:
+
+**1. [Most promising task]**
+   Location: `src/path/to/file.ts:42`
+   Scope: ~1-2 files, ~20-30 lines
+   Why it's good: [brief reason]
+
+**2. [Second task]**
+   Location: `src/another/file.ts`
+   Scope: ~1 file, ~15 lines
+   Why it's good: [brief reason]
+
+**3. [Third task]**
+   Location: [location]
+   Scope: [estimate]
+   Why it's good: [brief reason]
+
+**4. Something else?**
+   Tell me what you'd like to work on.
+
+Which task interests you? (Pick a number or describe your own)
+```
+
+**If nothing found:** Fall back to asking what the user wants to build:
+> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
+
+### Scope Guardrail
+
+If the user picks or describes something too large (major feature, multi-day work):
+
+```
+That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
+
+For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
+
+**Options:**
+1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
+2. **Pick something else** - One of the other suggestions, or a different small task?
+3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
+
+What would you prefer?
+```
+
+Let the user override if they insist—this is a soft guardrail.
+
+---
+
+## Phase 3: Explore Demo
+
+Once a task is selected, briefly demonstrate explore mode:
+
+```
+Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
+```
+
+Spend 1-2 minutes investigating the relevant code:
+- Read the file(s) involved
+- Draw a quick ASCII diagram if it helps
+- Note any considerations
+
+```
+## Quick Exploration
+
+[Your brief analysis—what you found, any considerations]
+
+┌─────────────────────────────────────────┐
+│   [Optional: ASCII diagram if helpful]  │
+└─────────────────────────────────────────┘
+
+Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
+
+Now let's create a change to hold our work.
+```
+
+**PAUSE** - Wait for user acknowledgment before proceeding.
+
+---
+
+## Phase 4: Create the Change
+
+**EXPLAIN:**
+```
+## Creating a Change
+
+A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
+
+Let me create one for our task.
+```
+
+**DO:** Create the change with a derived kebab-case name:
+```bash
+openspec new change "<derived-name>"
+```
+
+**SHOW:**
+```
+Created: `openspec/changes/<name>/`
+
+The folder structure:
+```
+openspec/changes/<name>/
+├── proposal.md    ← Why we're doing this (empty, we'll fill it)
+├── design.md      ← How we'll build it (empty)
+├── specs/         ← Detailed requirements (empty)
+└── tasks.md       ← Implementation checklist (empty)
+```
+
+Now let's fill in the first artifact—the proposal.
+```
+
+---
+
+## Phase 5: Proposal
+
+**EXPLAIN:**
+```
+## The Proposal
+
+The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
+
+I'll draft one based on our task.
+```
+
+**DO:** Draft the proposal content (don't save yet):
+
+```
+Here's a draft proposal:
+
+---
+
+## Why
+
+[1-2 sentences explaining the problem/opportunity]
+
+## What Changes
+
+[Bullet points of what will be different]
+
+## Capabilities
+
+### New Capabilities
+- `<capability-name>`: [brief description]
+
+### Modified Capabilities
+<!-- If modifying existing behavior -->
+
+## Impact
+
+- `src/path/to/file.ts`: [what changes]
+- [other files if applicable]
+
+---
+
+Does this capture the intent? I can adjust before we save it.
+```
+
+**PAUSE** - Wait for user approval/feedback.
+
+After approval, save the proposal:
+```bash
+openspec instructions proposal --change "<name>" --json
+```
+Then write the content to `openspec/changes/<name>/proposal.md`.
+
+```
+Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
+
+Next up: specs.
+```
+
+---
+
+## Phase 6: Specs
+
+**EXPLAIN:**
+```
+## Specs
+
+Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
+
+For a small task like this, we might only need one spec file.
+```
+
+**DO:** Create the spec file:
+```bash
+# Unix/macOS
+mkdir -p openspec/changes/<name>/specs/<capability-name>
+# Windows (PowerShell)
+# New-Item -ItemType Directory -Force -Path "openspec/changes/<name>/specs/<capability-name>"
+```
+
+Draft the spec content:
+
+```
+Here's the spec:
+
+---
+
+## ADDED Requirements
+
+### Requirement: <Name>
+
+<Description of what the system should do>
+
+#### Scenario: <Scenario name>
+
+- **WHEN** <trigger condition>
+- **THEN** <expected outcome>
+- **AND** <additional outcome if needed>
+
+---
+
+This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
+```
+
+Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
+
+---
+
+## Phase 7: Design
+
+**EXPLAIN:**
+```
+## Design
+
+The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
+
+For small changes, this might be brief. That's fine—not every change needs deep design discussion.
+```
+
+**DO:** Draft design.md:
+
+```
+Here's the design:
+
+---
+
+## Context
+
+[Brief context about the current state]
+
+## Goals / Non-Goals
+
+**Goals:**
+- [What we're trying to achieve]
+
+**Non-Goals:**
+- [What's explicitly out of scope]
+
+## Decisions
+
+### Decision 1: [Key decision]
+
+[Explanation of approach and rationale]
+
+---
+
+For a small task, this captures the key decisions without over-engineering.
+```
+
+Save to `openspec/changes/<name>/design.md`.
+
+---
+
+## Phase 8: Tasks
+
+**EXPLAIN:**
+```
+## Tasks
+
+Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
+
+These should be small, clear, and in logical order.
+```
+
+**DO:** Generate tasks based on specs and design:
+
+```
+Here are the implementation tasks:
+
+---
+
+## 1. [Category or file]
+
+- [ ] 1.1 [Specific task]
+- [ ] 1.2 [Specific task]
+
+## 2. Verify
+
+- [ ] 2.1 [Verification step]
+
+---
+
+Each checkbox becomes a unit of work in the apply phase. Ready to implement?
+```
+
+**PAUSE** - Wait for user to confirm they're ready to implement.
+
+Save to `openspec/changes/<name>/tasks.md`.
+
+---
+
+## Phase 9: Apply (Implementation)
+
+**EXPLAIN:**
+```
+## Implementation
+
+Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
+```
+
+**DO:** For each task:
+
+1. Announce: "Working on task N: [description]"
+2. Implement the change in the codebase
+3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
+4. Mark complete in tasks.md: `- [ ]` → `- [x]`
+5. Brief status: "✓ Task N complete"
+
+Keep narration light—don't over-explain every line of code.
+
+After all tasks:
+
+```
+## Implementation Complete
+
+All tasks done:
+- [x] Task 1
+- [x] Task 2
+- [x] ...
+
+The change is implemented! One more step—let's archive it.
+```
+
+---
+
+## Phase 10: Archive
+
+**EXPLAIN:**
+```
+## Archiving
+
+When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
+
+Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
+```
+
+**DO:**
+```bash
+openspec archive "<name>"
+```
+
+**SHOW:**
+```
+Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
+
+The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
+```
+
+---
+
+## Phase 11: Recap & Next Steps
+
+```
+## Congratulations!
+
+You just completed a full OpenSpec cycle:
+
+1. **Explore** - Thought through the problem
+2. **New** - Created a change container
+3. **Proposal** - Captured WHY
+4. **Specs** - Defined WHAT in detail
+5. **Design** - Decided HOW
+6. **Tasks** - Broke it into steps
+7. **Apply** - Implemented the work
+8. **Archive** - Preserved the record
+
+This same rhythm works for any size change—a small fix or a major feature.

+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+name: "OPSX: Sync"
+description: Sync delta specs from a change to main specs
+category: Workflow
+tags: [workflow, specs, experimental]
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Find delta specs**
+
+   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+3. **For each delta spec, apply changes to main specs**
+
+   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+4. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+description: Verify implementation matches change artifacts before archiving
+category: Workflow
+tags: [workflow, verify, experimental]
+---
+
+Verify that an implementation matches the change artifacts (specs, tasks, design).
+
+**Input**: Optionally specify a change name after `/opsx:verify` (e.g., `/opsx:verify add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have implementation tasks (tasks artifact exists).
+   Include the schema used for each change if available.
+   Mark changes with incomplete tasks as "(In Progress)".
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifacts exist for this change
+
+3. **Get the change directory and load artifacts**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns the change directory and `contextFiles` (artifact ID -> array of concrete file paths). Read all available artifacts from `contextFiles`.
+
+4. **Initialize verification report structure**
+
+   Create a report structure with three dimensions:
+   - **Completeness**: Track tasks and spec coverage
+   - **Correctness**: Track requirement implementation and scenario coverage
+   - **Coherence**: Track design adherence and pattern consistency
+
+   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
+
+5. **Verify Completeness**
+
+   **Task Completion**:
+   - If `contextFiles.tasks` exists, read every file path in it
+   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
+   - Count complete vs total tasks
+   - If incomplete tasks exist:
+     - Add CRITICAL issue for each incomplete task
+     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
+
+   **Spec Coverage**:
+   - If delta specs exist in `openspec/changes/<name>/specs/`:
+     - Extract all requirements (marked with "### Requirement:")
+     - For each requirement:
+       - Search codebase for keywords related to the requirement
+       - Assess if implementation likely exists
+     - If requirements appear unimplemented:
+       - Add CRITICAL issue: "Requirement not found: <requirement name>"
+       - Recommendation: "Implement requirement X: <description>"
+
+6. **Verify Correctness**
+
+   **Requirement Implementation Mapping**:
+   - For each requirement from delta specs:
+     - Search codebase for implementation evidence
+     - If found, note file paths and line ranges
+     - Assess if implementation matches requirement intent
+     - If divergence detected:
+       - Add WARNING: "Implementation may diverge from spec: <details>"
+       - Recommendation: "Review <file>:<lines> against requirement X"
+
+   **Scenario Coverage**:
+   - For each scenario in delta specs (marked with "#### Scenario:"):
+     - Check if conditions are handled in code
+     - Check if tests exist covering the scenario
+     - If scenario appears uncovered:
+       - Add WARNING: "Scenario not covered: <scenario name>"
+       - Recommendation: "Add test or implementation for scenario: <description>"
+
+7. **Verify Coherence**
+
+   **Design Adherence**:
+   - If `contextFiles.design` exists:
+     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
+     - Verify implementation follows those decisions
+     - If contradiction detected:
+       - Add WARNING: "Design decision not followed: <decision>"
+       - Recommendation: "Update implementation or revise design.md to match reality"
+   - If no design.md: Skip design adherence check, note "No design.md to verify against"
+
+   **Code Pattern Consistency**:
+   - Review new code for consistency with project patterns
+   - Check file naming, directory structure, coding style
+   - If significant deviations found:
+     - Add SUGGESTION: "Code pattern deviation: <details>"
+     - Recommendation: "Consider following project pattern: <example>"
+
+8. **Generate Verification Report**
+
+   **Summary Scorecard**:
+   ```
+   ## Verification Report: <change-name>
+
+   ### Summary
+   | Dimension    | Status           |
+   |--------------|------------------|
+   | Completeness | X/Y tasks, N reqs|
+   | Correctness  | M/N reqs covered |
+   | Coherence    | Followed/Issues  |
+   ```
+
+   **Issues by Priority**:
+
+   1. **CRITICAL** (Must fix before archive):
+      - Incomplete tasks
+      - Missing requirement implementations
+      - Each with specific, actionable recommendation
+
+   2. **WARNING** (Should fix):
+      - Spec/design divergences
+      - Missing scenario coverage
+      - Each with specific recommendation
+
+   3. **SUGGESTION** (Nice to fix):
+      - Pattern inconsistencies
+      - Minor improvements
+      - Each with specific recommendation
+
+   **Final Assessment**:
+   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
+   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
+   - If all clear: "All checks passed. Ready for archive."
+
+**Verification Heuristics**
+
+- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
+- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
+- **Coherence**: Look for glaring inconsistencies, don't nitpick style
+- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
+- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
+
+**Graceful Degradation**
+
+- If only tasks.md exists: verify task completion only, skip spec/design checks
+- If tasks + specs exist: verify completeness and correctness, skip design
+- If full artifacts: verify all three dimensions
+- Always note which checks were skipped and why
+
+**Output Format**
+
+Use clear markdown with:
+- Table for summary scorecard
+- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
+- Code references in format: `file.ts:123`
+- Specific, actionable recommendations
+- No vague suggestions like "consider reviewing"

+# Comet 阶段 5：归档（Archive）
+
+## 前置条件
+
+- 验证已通过（阶段 4 完成）
+- 分支已处理
+- `openspec/changes/<name>/.comet.yaml` 中 `verify_result: pass`
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+bash "$COMET_STATE" check <name> archive
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+### 1. 执行归档
+
+运行归档脚本，自动完成以下全部步骤：
+
+```bash
+bash "$COMET_ARCHIVE" "<change-name>"
+```
+
+脚本自动执行：
+1. 入口状态验证（phase=archive, verify_result=pass, archived=false）
+2. Delta spec 同步到主 spec
+3. Design doc 前置元数据标注（archived-with, status）
+4. Plan 前置元数据标注（archived-with）
+5. 移动 change 到归档目录
+6. 通过 `comet-state transition <archive-name> archived` 更新 `archived: true`
+
+如脚本返回非零退出码，报告错误并停止。
+如脚本返回零退出码，归档完成。
+脚本摘要中的 `X/Y steps succeeded` 以真实执行步骤计数，不会因 delta spec 同步或文档标注重复累计。
+
+当待同步的 delta spec 与已有主 spec 不一致时，脚本会在覆盖前打印 unified diff 预览，帮助确认归档同步内容。
+
+如需预览而不实际执行，使用 `--dry-run` 参数。
+
+### 2. 生命周期闭环
+
+Spec 生命周期在此完成：
+```
+brainstorming → delta spec → 实施 → 验证 → 主 spec 覆盖 → design doc 标注 → 归档
+```
+
+## 退出条件
+
+- 归档脚本执行成功（退出码 0）
+- 归档目录 `openspec/changes/archive/YYYY-MM-DD-<change-name>/` 存在
+- 归档后的 `.comet.yaml` 中 `archived: true`
+
+归档脚本会把 `openspec/changes/<name>/` 移动到 `openspec/changes/archive/YYYY-MM-DD-<name>/`。归档成功后**不要再对原 change 名运行** `bash "$COMET_GUARD" <change-name> archive`，因为原活跃目录已经不存在。归档完整性以脚本退出码和归档目录状态为准。
+
+## 完成
+
+Comet 流程全部完成。如需开始新工作，调用 `/comet` 或 `/comet-open`。

+# Comet 阶段 3：计划与构建（Build）
+
+## 前置条件
+
+- Design Doc 已创建（阶段 2 完成）
+- 活跃 change 存在
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+bash "$COMET_STATE" check <name> build
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：build 阶段所有操作可安全重复执行。读取 `.comet.yaml` 的 `phase` 字段确认仍在 build 阶段，读取 plan 文件头的 `base-ref`，再读取 tasks.md 找到第一个未勾选任务继续执行。已提交的任务不得重复提交。
+
+### 1. 制定计划
+
+**立即执行：** 使用 Skill 工具加载 `superpowers:writing-plans` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引制定计划。计划要求：
+- 保存至 `docs/superpowers/plans/YYYY-MM-DD-<feature>.md`
+- 引用设计文档，拆分为可执行任务
+- **Plan 文件头必须包含关联元数据**：
+
+```yaml
+---
+change: <openspec-change-name>
+design-doc: docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md
+base-ref: <git rev-parse HEAD before implementation>
+---
+```
+
+`base-ref` 用于验证阶段跨提交统计改动规模。创建计划时先记录当前提交：
+
+```bash
+git rev-parse HEAD
+```
+
+### 2. 更新计划状态
+
+先记录 plan 路径：
+
+```bash
+bash "$COMET_STATE" set <name> plan docs/superpowers/plans/YYYY-MM-DD-feature.md
+```
+
+无需手动更新 phase，guard 会在退出条件满足后自动流转。
+
+### 3. 选择工作方式
+
+计划已写入当前分支。在开始执行前，**一次性询问用户**选择工作区隔离方式和执行方式：
+
+**工作区隔离**：
+
+| 选项 | 方式 | 说明 |
+|------|------|------|
+| A | 创建分支 | 在当前仓库创建新分支，简单快速 |
+| B | 创建 Worktree | 隔离工作区，完全独立，适合并行开发 |
+
+**推荐规则**：
+- 变更涉及 ≤ 3 个文件 → 推荐 A
+- 需要并行开发、当前分支有未提交工作 → 推荐 B
+
+**执行方式**：
+
+| 选项 | 技能 | 适用场景 |
+|------|------|---------|
+| A | `superpowers:subagent-driven-development` | 任务独立、复杂度高、需要双阶段审查 |
+| B | `superpowers:executing-plans` | 任务简单、无子agent环境、轻量快速 |
+
+**执行方式推荐规则**：
+- 任务数 ≥ 3 → 推荐 A
+- 任务数 ≤ 2 且无跨模块依赖 → 推荐 B
+- 来自 hotfix 路径 → 推荐 B
+
+这是用户决策点。**必须使用 AskUserQuestion 工具暂停并等待用户明确选择隔离方式和执行方式**，不得根据推荐规则自行选择 `branch` 或 `worktree`，也不得根据推荐规则自行选择执行方式。推荐规则只能用于说明建议，不能替代用户确认。禁止仅输出文字提示后继续执行。
+
+用户选择后，更新 `isolation` 和 `build_mode` 字段：
+
+```bash
+bash "$COMET_STATE" set <name> isolation <branch|worktree>
+bash "$COMET_STATE" set <name> build_mode <subagent-driven-development|executing-plans|direct>
+```
+
+`isolation` 是脚本级硬约束。full workflow 初始化时可以为 `null`，但只允许存在到本步骤之前。若保持 `null`，`build → verify` 的 guard 和 `comet-state transition build-complete` 都会失败。
+
+`build_mode` 默认仅 hotfix/tweak preset 使用 `direct`。full workflow 不得默认使用 `direct`。只有用户明确要求跳过计划执行技能，且你已记录显式 override 时，才允许：
+
+```bash
+bash "$COMET_STATE" set <name> direct_override true
+bash "$COMET_STATE" set <name> build_mode direct
+```
+
+没有 `direct_override: true` 时，full workflow 的 `build_mode=direct` 会被 guard 和状态转换同时拦截。
+
+**执行隔离**：
+
+- **branch**：执行 `git checkout -b <change-name>`，后续工作在新分支上进行
+- **worktree**：必须使用 Skill 工具加载 `superpowers:using-git-worktrees` 技能创建隔离工作区。禁止用普通 shell 命令或原生工具绕过该技能；如该技能不可用，停止流程并提示安装或启用 Superpowers 技能。
+
+创建隔离后，确认计划文件可访问（分支方式天然可访问；worktree 方式需确认计划已提交）。
+
+**加载执行技能**：使用 Skill 工具加载对应技能。禁止跳过此步骤。
+
+如所选 Superpowers 技能不可用，停止流程并提示安装或启用对应技能，不要用普通对话替代该步骤。
+
+技能加载后，按其指引执行：
+- 按计划执行任务
+- 完成 tasks.md 勾选（`- [ ]` → `- [x]`）
+- 每个任务完成后提交代码
+
+### 4. Spec 增量更新
+
+实施过程中发现初版 spec 不完整时，按变更规模分级处理：
+
+| 规模 | 触发条件 | 做法 |
+|------|---------|------|
+| 小 | 遗漏验收场景、边界条件 | 直接编辑 delta spec + design.md，追加 tasks.md 任务 |
+| 中 | 接口变更、新增组件、数据流变化 | **使用 AskUserQuestion 工具暂停并等待用户确认后**，必须使用 Skill 工具加载 `superpowers:brainstorming` 更新 Design Doc + delta spec |
+| 大 | 全新 capability 需求 | **必须使用 AskUserQuestion 工具暂停并等待用户确认拆分**；用户确认后，通过 `/comet-open` 创建独立 change |
+
+**50% 阈值判定**：以 tasks.md 初始任务总数为基准，若新增任务数超过该总数的一半，视为超出原计划范围，**必须使用 AskUserQuestion 工具暂停并等待用户决定是否拆分为新 change**。
+
+创建独立 change 时必须调用 `/comet-open`，不得直接调用 `/opsx:new`。`/comet-open` 会同时创建 OpenSpec 产物和 `.comet.yaml`，避免新 change 脱离 Comet 状态机。
+
+**原则**：
+- delta spec 是活文档，本阶段期间随时可修改
+- 每次更新应提交，commit message 说明变更原因
+- 不提前同步到 main spec，归档时统一同步
+- 小规模增量直接改 delta spec 时，应在 commit message 中注明，便于归档时判断 design doc 漂移
+
+### 5. 上下文管理
+
+Build 是最长阶段，可能跨越大量任务。为支持上下文压缩后断点恢复：
+
+- **每完成一个 task**：立即勾选 tasks.md 并提交代码，确保 `.comet.yaml` 和文件状态持久化
+- **上下文压缩后恢复**：先运行 `bash "$COMET_STATE" check <change-name> build --recover`，脚本输出结构化恢复上下文（isolation/build_mode 状态、plan 路径、任务完成进度、恢复动作）。根据 Recovery action 决定下一步。
+- **用户手动修改恢复**：按 `comet/reference/dirty-worktree.md` 协议处理未提交改动。该协议定义了检查步骤、归因分类和禁令。build 阶段的特殊处理：
+  1. 归因后，若 diff 暗示计划或 spec 已变化，按 Step 4「Spec 增量更新」分级处理
+- **长任务拆分**：单任务超过 200 行代码变更时，考虑拆分为多个子任务分别提交
+
+## 退出条件
+
+- tasks.md 全部勾选
+- 代码已提交
+- 已显式运行项目对应的构建/测试命令并通过（不要只依赖 guard 自动猜测）
+- `isolation` 已写为 `branch` 或 `worktree`
+- `build_mode` 已写为 `subagent-driven-development`、`executing-plans` 或带显式 override 的 `direct`
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> build --apply`，全部 PASS 后自动流转到 `phase: verify`
+
+Guard 会优先读取项目配置中的命令：
+
+```yaml
+build_command: <build command>
+verify_command: <verify command>
+```
+
+配置位置可为 change 的 `.comet.yaml`，也可为仓库根目录的 `.comet.yaml` / `comet.yaml` / `.comet.yml` / `comet.yml`。
+未配置时才回退到 `npm run build`、Maven 或 Cargo 的默认探测。构建失败时 guard 会打印失败命令输出，作为排查证据。
+
+退出前运行 guard 自动流转：
+
+```bash
+bash "$COMET_GUARD" <change-name> build --apply
+```
+
+状态文件自动更新为 `phase: verify`、`verify_result: pending`。
+
+## 自动流转
+
+退出条件满足后（包括用户选择工作方式），自动流转到下一阶段：
+
+> **REQUIRED NEXT SKILL:** 调用 `comet-verify` skill 进入验证与收尾阶段。

+# Comet 阶段 2：深度设计（Design）
+
+## 前置条件
+
+- 活跃 change 已存在（proposal.md、design.md、tasks.md）
+- 无 Design Doc（`docs/superpowers/specs/` 下无对应文件）
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+bash "$COMET_STATE" check <name> design
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：所有 design 阶段操作可以安全重试。如果 `handoff_context` 和 `handoff_hash` 已存在，先确认它们与当前产物一致再决定是否重新生成。
+
+### 1a. 生成 OpenSpec → Superpowers 交接包
+
+**必须由脚本生成，不允许 agent 临场手写 summary 代替。**
+
+```bash
+bash "$COMET_HANDOFF" <change-name> design --write
+```
+
+脚本会生成并记录：
+
+```
+openspec/changes/<name>/.comet/handoff/design-context.json
+openspec/changes/<name>/.comet/handoff/design-context.md
+```
+
+并在 `.comet.yaml` 写入：
+
+```yaml
+handoff_context: openspec/changes/<name>/.comet/handoff/design-context.json
+handoff_hash: <sha256>
+```
+
+默认交接包是 **compact 可追溯摘录**，不是 agent summary：
+- `design-context.json`：机器索引，包含 change、phase、canonical spec、source paths、hash
+- `design-context.md`：供 Superpowers 阅读的上下文，包含脚本标记、source path、line range、sha256、确定性摘录
+- 超出摘录预算时标记 `[TRUNCATED]`，并保留 Full source 路径
+
+如确实需要全文上下文，可显式运行：
+
+```bash
+bash "$COMET_HANDOFF" <change-name> design --write --full
+```
+
+交接包来源来自 OpenSpec open 阶段产物：
+- `proposal.md`：目标、动机、范围、非目标
+- `design.md`：高层架构决策、方案约束
+- `tasks.md`：初始任务边界
+- `specs/*/spec.md`：delta 能力规格
+
+### 1b. 执行 Brainstorming（带上下文）
+
+**立即执行：** 使用 Skill 工具加载 `superpowers:brainstorming` 技能，ARGUMENTS 包含：
+
+```
+Change: <change-name>
+OpenSpec Context Pack: openspec/changes/<name>/.comet/handoff/design-context.md
+Machine handoff: openspec/changes/<name>/.comet/handoff/design-context.json
+
+OpenSpec 产物是上游事实源，不要重新定义需求，不要重写 proposal/spec。
+你的任务是基于交接包做深度技术设计：实现方案、技术风险、测试策略、边界条件。
+如发现 OpenSpec delta spec 缺少验收场景，只能提出 Spec Patch，并回写 OpenSpec delta spec；不要在 Design Doc 中创建第二份需求 spec。
+
+Design Doc frontmatter 必须最小化，只包含：
+---
+comet_change: <change-name>
+role: technical-design
+canonical_spec: openspec
+---
+
+跳过重复上下文探索，直接进入设计提问。
+```
+
+禁止跳过此步骤，禁止在未加载该技能的情况下继续。
+
+如 `superpowers:brainstorming` 不可用，停止流程并提示安装或启用 Superpowers 技能，不要用普通对话替代该步骤。
+
+技能加载后，按其指引产出设计方案（以对话形式呈现）：
+- 技术方案：架构、数据流、关键技术选型与风险
+- 测试策略
+- 如需补充验收场景，标明将回写的 delta spec 变更
+
+brainstorming 阶段不写入 Design Doc 文件，仅产出设计方案供 Step 1c 用户确认。确认后才创建 `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md` 并回写 delta spec。
+
+### 1c. 用户确认设计方案（阻塞点）
+
+brainstorming 产出设计方案后，**必须使用 AskUserQuestion 工具暂停并等待用户明确确认设计方案**。不得在用户确认前创建最终 Design Doc、写入 `design_doc`、运行 design guard，或进入 `/comet-build`。也不得仅输出文字提示后继续执行。
+
+暂停时只展示必要摘要：
+- 采用的技术方案
+- 关键取舍与风险
+- 测试策略
+- 如有 Spec Patch，列出将回写的 delta spec 变更
+
+用户明确确认后，才继续 Step 2。若用户要求调整，继续 brainstorming 迭代，直到用户确认。
+
+### 2. 更新 Comet 状态
+
+先记录 design_doc 路径。如果 Step 1c 回写了 delta spec（新增或修改了 `specs/*/spec.md`），必须重新生成 handoff 以更新 hash：
+
+```bash
+# 记录 design_doc 路径
+bash "$COMET_STATE" set <name> design_doc docs/superpowers/specs/YYYY-MM-DD-topic-design.md
+
+# 如有 delta spec 变更，重新生成 handoff（更新 hash）
+bash "$COMET_HANDOFF" <change-name> design --write
+
+# 自动流转到下一阶段
+bash "$COMET_GUARD" <change-name> design --apply
+```
+
+如果没有 delta spec 变更，跳过 handoff 重新生成步骤。状态文件自动更新，无需手动编辑其他字段。
+
+## 退出条件
+
+- Design Doc 已创建并保存
+- Design Doc frontmatter 包含 `comet_change`、`role: technical-design`、`canonical_spec: openspec`
+- `handoff_context` 和 `handoff_hash` 已写入 `.comet.yaml`（由 guard 强制校验）
+- `handoff_hash` 与当前 OpenSpec open 阶段产物一致（由 guard 强制校验）
+- `design-context.md` 必须是脚本生成，且包含 source path、mode、sha256 等可追溯标记（由 guard 强制校验）
+- 如有新能力或补充验收场景，OpenSpec delta spec 已创建/更新
+- `design_doc` 已写入 `.comet.yaml`
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> design --apply`，全部 PASS 后自动流转到 `phase: build`
+
+退出前必须使用 `--apply`：
+
+```bash
+bash "$COMET_GUARD" <change-name> design --apply
+```
+
+## 上下文压缩恢复
+
+design 阶段在 brainstorming 过程中可能触发上下文压缩。恢复时先运行：
+
+```bash
+bash "$COMET_STATE" check <change-name> design --recover
+```
+
+脚本输出结构化恢复上下文（阶段、已完成字段、待完成字段、恢复动作）。按 Recovery action 判断下一步。
+
+## 自动流转
+
+退出条件满足后（包括用户确认设计方案），自动流转到下一阶段：
+
+> **REQUIRED NEXT SKILL:** 调用 `comet-build` skill 进入计划与构建阶段。

+
+# Comet 预设路径：Hotfix
+
+快速 bug fix 工作流：open → build → verify → archive。跳过 brainstorming 和完整 plan，适用于行为修复、不涉及新 capability 设计的场景。
+
+**适用条件**（必须全部满足）：
+1. 修复已有功能的 bug，不新增 capability
+2. 不涉及接口变更或架构调整
+3. 改动范围可预估（通常 ≤ 2 个文件）
+
+**不适用**：如修复过程发现需要架构调整，应升级为完整 `/comet` 流程。
+
+---
+
+## 流程（preset workflow，5 阶段）
+
+执行链路：open → build → verify → archive。Hotfix 为每个阶段提供默认决策：精简开启、直接构建、按规模验证、验证通过后归档。
+
+开始前先定位 Comet 脚本：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+```
+
+### 1. 快速开启（preset open）
+
+复用 Comet open 能力创建 change，但使用 hotfix 默认值：不执行 `openspec-explore` 长探索，直接进入精简 change 创建。
+
+**立即执行：** 使用 Skill 工具加载 `openspec-new-change` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引创建精简版产物：
+  - `proposal.md` — 问题描述 + 根因分析 + 修复目标（无需方案对比）
+  - `design.md` — 修复方案（1 个即可，无需多方案对比）
+  - `tasks.md` — 修复任务清单
+- **无需 delta spec**（除非修复改变了已有 spec 的验收场景）
+
+初始化 Comet 状态文件：
+
+```bash
+bash "$COMET_STATE" init <name> hotfix
+```
+
+初始化后验证状态：
+
+```bash
+bash "$COMET_STATE" check <name> open
+```
+
+阶段守卫完成 open → build 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> open --apply
+```
+
+### 2. 直接构建（preset build）
+
+使用 hotfix 默认值：`build_mode: direct`。跳过 `superpowers:brainstorming` 和 `superpowers:writing-plans`（除非任务 > 3 个；若超过 3 个任务，转入 `/comet-build` 的计划与执行方式选择）。
+
+继续或开始修改前，按 `comet/reference/dirty-worktree.md` 协议处理未提交改动。若归因后发现修复范围超出 hotfix，按本文件“升级条件”处理。
+
+**立即执行：** 按 tasks.md 逐个执行任务：
+
+1. 读取 `openspec/changes/<name>/tasks.md`，获取未完成任务列表
+2. 对每个未完成任务：
+   - 根据任务描述修改代码
+   - 运行项目格式化命令（如 `mvn spotless:apply`、`npm run format` 等）
+   - 运行相关测试确认通过
+   - 将 tasks.md 中对应 `- [ ]` 勾选为 `- [x]`
+   - 提交代码，commit message 格式：`fix: <简述修复>`
+3. 全部任务完成后，显式运行项目相关测试和构建命令
+
+**如修复影响已有 spec 验收场景**：
+- 在 `openspec/changes/<name>/specs/<capability>/spec.md` 创建 delta spec
+- 仅包含 `## MODIFIED Requirements` 部分
+
+### 3. 根因消除检查
+
+**在运行 build guard 之前执行**，确保修复确实消除了问题根因：
+
+1. 读取 proposal.md 中的 bug 描述和根因
+2. 搜索验证问题代码不再存在
+3. 如根因未消除，回到 Step 2 继续修复（此时仍在 build 阶段，无需状态回退）
+
+**升级条件**：
+- 根因消除检查发现深层架构问题 → 停止 hotfix，按升级条件阻塞确认处理
+- 修复需要额外接口变更 → 停止 hotfix，按升级条件阻塞确认处理
+
+根因确认消除后，运行阶段守卫完成 build → verify 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> build --apply
+```
+
+状态文件自动更新为 `phase: verify`、`verify_result: pending`，然后进入验证。
+
+### 4. 验证（preset verify）
+
+复用 `/comet-verify`，由 comet-verify 的规模评估决定轻量或完整验证。
+
+**立即执行：** 使用 Skill 工具加载 `comet-verify` 技能。禁止跳过此步骤。
+
+无 delta spec 的小范围 hotfix 通常满足轻量验证条件（≤ 3 tasks、≤ 2 files），comet-verify 的规模评估会选择轻量验证路径（5 项快速检查）。若 hotfix 创建了 delta spec，则根据 comet-verify 的规模评估规则进入完整验证路径。
+
+验证通过后，按 `/comet-verify` 的规则将 `.comet.yaml` 的 `verify_result` 记录为 `pass`，归档前不得跳过该状态。
+
+### 5. 归档（preset archive）
+
+复用 `/comet-archive`。归档前必须满足 `.comet.yaml` 中 `verify_result: pass`。
+
+**立即执行：** 使用 Skill 工具加载 `comet-archive` 技能进行归档。禁止跳过此步骤。
+如有 delta spec，按 comet-archive 规则同步到 main spec，并处理关联 Design Doc 与 Plan 的归档标注。
+
+---
+
+## 连续执行模式
+
+<IMPORTANT>
+Hotfix 流程为 **一次性连续执行**。调用 `/comet-hotfix` 后，agent 在 hotfix 自有步骤间自动推进，不主动停顿。但以下情况必须暂停等待用户确认：
+
+1. 遇到升级条件（见"升级条件"章节），**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整流程
+2. 任务超过 3 个转入 `/comet-build` 时的工作区隔离和执行方式选择
+3. 验证阶段（comet-verify）的验证失败决策和分支处理决策
+
+执行顺序：快速开启 → 直接构建 → 根因消除检查 → 验证 → 归档 → 完成
+
+每个阶段完成后立即进入下一阶段。阶段内部仍必须按上文要求调用对应 Comet/OpenSpec/Superpowers skill，被调用的 skill 如有自己的用户决策点，按该 skill 规则执行。
+</IMPORTANT>
+
+---
+
+## 升级条件
+
+满足以下**任一**条件时，停止 hotfix 流程，升级为完整 `/comet`：
+
+| 条件 | 说明 |
+|------|------|
+| 改动涉及 **3+ 文件** | 超出单点修复范围 |
+| 架构变更 | 新模块、新接口、新依赖 |
+| 数据库 schema 变更 | 结构性调整 |
+| 引入新的 public API | 修复产生了新的对外接口 |
+| 修复范围超出单一函数/模块 | 需要多处协调修改 |
+
+满足升级条件时**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整 `/comet` 流程。不得直接进入 `/comet-design`，不得自动补充 Design Doc。不得仅输出文字提示后继续执行。
+
+用户确认升级后，**必须先更新 workflow 字段**再进入完整流程：
+
+```bash
+bash "$COMET_STATE" set <name> workflow full
+```
+
+然后在当前 change 基础上补充 Design Doc：**立即使用 Skill 工具加载 `comet-design` skill**，后续正常走完整流程。若用户不确认升级，停止 hotfix 并报告当前变更已超出 hotfix 适用范围。

+---
+
+# Comet 阶段 1：开启（Open）
+
+## 前置条件
+
+- 无活跃 change，或用户希望创建新 change
+
+## 步骤
+
+### 1. 探索想法
+
+**立即执行：** 使用 Skill 工具加载 `openspec-explore` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引自由探索问题空间。
+
+### 2. 创建 Change 结构 + 初始化状态
+
+**立即执行：** 使用 Skill 工具加载 `openspec-new-change` 技能。若用户意图未明确、需要先形成建议，改为加载 `openspec-propose`。禁止跳过此步骤。
+
+**命名与范围守卫**：change name 必须使用用户指定或通过 AskUserQuestion 确认的名称，不得自动生成或推断。变更范围必须与用户描述一致，不得自行扩大或缩小。
+
+确认以下产物已创建：
+
+```
+openspec/changes/<name>/
+├── .openspec.yaml
+├── .comet.yaml
+├── proposal.md       # Why + What：问题、目标、范围
+├── design.md         # How（高层）：架构决策、方案选型
+└── tasks.md          # 任务清单（勾选框）
+```
+
+创建 `.comet.yaml` 状态文件：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+
+if [ -z "$COMET_STATE" ] || [ -z "$COMET_GUARD" ]; then
+  echo "ERROR: Comet scripts not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+
+bash "$COMET_STATE" init <name> full
+```
+
+### 3. 入口状态验证
+
+验证状态机已正确初始化：
+
+```bash
+bash "$COMET_STATE" check <name> open
+```
+
+验证通过后继续 Step 4。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：open 阶段所有操作可安全重复执行。如 `.comet.yaml` 已处于 `phase: open` 且三个产物文件均已存在，跳过已完成步骤，从第一个缺失步骤继续。
+
+### 4. 内容完整性检查
+
+确认三个文档内容完整：
+- **proposal.md**：问题背景、目标、范围、非目标
+- **design.md**：高层架构决策、方案选型、数据流
+- **tasks.md**：任务列表，每个任务有明确描述
+
+**文件存在性验证**：逐个确认三个文件路径存在且非空。任一文件缺失或为空时，不得进入 Step 5 或执行阶段守卫，必须回到创建步骤补充。
+
+### 5. 用户审视确认（阻塞点）
+
+三个文档创建完成且内容完整性检查通过后，**必须使用 AskUserQuestion 工具暂停并等待用户确认**。不得在用户确认前执行阶段守卫或自动流转。
+
+AskUserQuestion 必须以单选题形式呈现，包含以下摘要和选项：
+
+**摘要内容**：
+- **proposal.md**：问题背景、目标、范围
+- **design.md**：高层架构决策、方案选型
+- **tasks.md**：任务数量和关键任务描述
+
+**选项**：
+- 「确认，继续下一阶段」— 产物符合预期，执行阶段守卫流转
+- 「需要调整」— 附带调整说明，修改后重新请求确认
+
+用户选择「确认」后继续执行退出条件。用户选择「需要调整」时，按其说明修改对应文件，然后重新使用 AskUserQuestion 请求确认。
+
+## 退出条件
+
+- proposal.md、design.md、tasks.md 均已创建且内容完整
+- **用户已确认** proposal、design、tasks 内容符合预期
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> open --apply`，全部 PASS 后自动流转到下一阶段
+
+退出前必须使用 `--apply`，否则 `.comet.yaml` 仍停留在 `phase: open`，下一阶段入口检查会失败。
+
+```bash
+bash "$COMET_GUARD" <change-name> open --apply
+```
+
+完整流程会自动更新为 `phase: design`；hotfix/tweak preset 会自动更新为 `phase: build`。
+
+## 自动流转
+
+用户确认后，退出条件满足，自动流转到下一阶段：
+
+> **REQUIRED NEXT SKILL（完整流程）:** 调用 `comet-design` skill 进入深度设计阶段。
+>
+> hotfix/tweak preset 由对应 preset skill 控制后续流转（phase 直接进入 build），不经过本节。

+---
+
+# Comet 预设路径：Tweak
+
+Tweak 是 Comet 五阶段能力的预设工作流，不是独立的平行流程。它复用 open、build、verify、archive 能力，仅跳过 brainstorming 和完整 plan。
+
+适用于非 bug 的小范围变更，例如文案调整、配置调整、文档或 prompt 的局部优化。
+
+**适用条件**（必须全部满足）：
+1. 不新增 capability
+2. 不改变架构
+3. 不涉及接口变化
+4. 通常不超过 3 个 tasks、4 个文件
+
+**不适用**：如变更过程中发现需要 capability、架构或接口调整，应升级为完整 `/comet` 流程。
+
+---
+
+## 流程（preset workflow，4 阶段）
+
+执行链路：open → lightweight build → light verify → archive。Tweak 为每个阶段提供默认决策：精简开启、轻量构建、轻量验证、验证通过后归档。
+
+开始前先定位 Comet 脚本：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+```
+
+### 1. 快速开启（preset open）
+
+复用 Comet open 能力创建 change，但使用 tweak 默认值：不执行 `openspec-explore` 长探索，直接进入精简 change 创建。
+
+**立即执行：** 使用 Skill 工具加载 `openspec-new-change` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引创建精简版产物：
+  - `proposal.md` — 变更动机 + 目标 + 范围
+  - `design.md` — 简短实现说明（无需方案对比）
+  - `tasks.md` — 不超过 3 个任务
+- **无需 delta spec**（除非变更改变了已有 spec 的验收场景；一旦需要 delta spec，升级为完整 `/comet`）
+
+初始化 Comet 状态文件：
+
+```bash
+bash "$COMET_STATE" init <name> tweak
+```
+
+初始化后验证状态：
+
+```bash
+bash "$COMET_STATE" check <name> open
+```
+
+阶段守卫完成 open → build 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> open --apply
+```
+
+### 2. 轻量构建（preset build）
+
+使用 tweak 默认值：`build_mode: direct`。跳过 `superpowers:brainstorming` 和 `superpowers:writing-plans`。
+
+继续或开始修改前，按 `comet/reference/dirty-worktree.md` 协议处理未提交改动。若归因后发现范围超出 tweak，按本文件“升级条件”处理。
+
+**立即执行：** 按 tasks.md 逐个执行任务：
+
+1. 读取 `openspec/changes/<name>/tasks.md`，获取未完成任务列表
+2. 对每个未完成任务：
+   - 根据任务描述修改目标文件
+   - 运行项目格式化命令（如 `mvn spotless:apply`、`npm run format` 等）
+   - 运行相关测试确认通过
+   - 将 tasks.md 中对应 `- [ ]` 勾选为 `- [x]`
+   - 提交代码，commit message 格式：`tweak: <简述变更>`
+3. 全部任务完成后，显式运行项目相关测试和构建命令
+4. 运行阶段守卫完成 build → verify 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> build --apply
+```
+
+状态文件自动更新为 `phase: verify`、`verify_result: pending`，然后进入验证。
+
+### 3. 轻量验证（preset verify）
+
+复用 `/comet-verify`。Tweak 必须保持轻量验证条件：≤ 3 tasks、≤ 4 files、无 delta spec、无新 capability。
+
+**立即执行：** 使用 Skill 工具加载 `comet-verify` 技能。禁止跳过此步骤。
+
+如规模评估进入完整验证路径，停止 tweak，按升级条件阻塞确认处理。
+
+验证通过后，按 `/comet-verify` 的规则将 `.comet.yaml` 的 `verify_result` 记录为 `pass`，归档前不得跳过该状态。
+
+### 4. 归档（preset archive）
+
+复用 `/comet-archive`。归档前必须满足 `.comet.yaml` 中 `verify_result: pass`。
+
+**立即执行：** 使用 Skill 工具加载 `comet-archive` 技能进行归档。禁止跳过此步骤。
+
+---
+
+## 连续执行模式
+
+<IMPORTANT>
+Tweak 流程为 **一次性连续执行**。调用 `/comet-tweak` 后，agent 在 tweak 自有步骤间自动推进，不主动停顿。但以下情况必须暂停等待用户确认：
+
+1. 遇到升级条件（见"升级条件"章节），**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整流程
+2. 验证阶段（comet-verify）的验证失败决策和分支处理决策
+
+执行顺序：快速开启 → 轻量构建 → 轻量验证 → 归档 → 完成
+
+每个阶段完成后立即进入下一阶段。阶段内部仍必须按上文要求调用对应 Comet/OpenSpec/Superpowers skill，被调用的 skill 如有自己的用户决策点，按该 skill 规则执行。
+</IMPORTANT>
+
+---
+
+## 升级条件
+
+满足以下**任一**条件时，停止 tweak 流程，升级为完整 `/comet`：
+
+| 条件 | 说明 |
+|------|------|
+| 改动涉及 **5+ 文件** | 超出小改动范围 |
+| 多模块协调修改 | 需要跨组件协调 |
+| 需要新增测试用例 **5+** | 变更复杂度上升 |
+| 配置项新增或删除 | 非值修改的配置变更 |
+| 需要新增 capability | 超出局部优化 |
+| 需要 delta spec | 影响了已有规格 |
+
+满足升级条件时**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整 `/comet` 流程。不得直接进入 `/comet-design`，不得自动补充 Design Doc。不得仅输出文字提示后继续执行。
+
+用户确认升级后，**必须先更新 workflow 字段**再进入完整流程：
+
+```bash
+bash "$COMET_STATE" set <name> workflow full
+```
+
+然后在当前 change 基础上补充 Design Doc：**立即使用 Skill 工具加载 `comet-design` skill**，后续正常走完整流程。若用户不确认升级，停止 tweak 并报告当前变更已超出 tweak 适用范围。

+# Comet 阶段 4：验证与收尾（Verify）
+
+## 前置条件
+
+- 代码已提交（阶段 3 完成）
+- tasks.md 全部任务已完成
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+bash "$COMET_STATE" check <change-name> verify
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：verify 阶段所有检查可安全重复执行。如 `verify_result` 已为 `pass` 且 `branch_status` 已为 `handled`，说明验证已完成，直接执行 guard 流转。如 `verify_result` 为 `pending`，从头开始验证。
+
+### 1. 改动规模评估
+
+执行规模评估：
+
+```bash
+bash "$COMET_STATE" scale <change-name>
+```
+
+脚本自动统计任务数、增量规格数、变更文件数，判断使用 light 或 full 验证模式，并设置 verify_mode 字段。
+
+验证开始前，按 `comet/reference/dirty-worktree.md` 协议检查并处理未提交改动。verify 阶段的特殊处理：
+
+1. 若 dirty diff 属于当前 change 且涉及实现、测试、tasks、delta spec 或 design doc 变更，不在 verify 阶段直接修复或提交；报告失败项并进入 Step 1b 的验证失败决策阻塞点
+2. 若 dirty diff 只是 verify 本阶段产物（例如验证报告草稿、分支处理记录），可继续在 verify 阶段完成并记录状态
+3. 若 dirty diff 已实现但 tasks.md 未勾选，视为 build 状态滞后；报告失败项并进入 Step 1b，由用户决定回退修复或接受偏差
+
+用户选择修复后，才允许回退到 build 阶段：
+
+```bash
+# 仅在用户确认修复后执行
+bash "$COMET_STATE" transition <change-name> verify-fail
+```
+
+注意：如果 build 阶段每个任务都已提交，脚本基于工作区 diff 的文件数可能低估改动规模。此时必须读取 plan 文件头的 `base-ref` 并用提交区间复核：
+
+```bash
+PLAN=$(bash "$COMET_STATE" get <change-name> plan)
+BASE_REF=$(grep '^base-ref:' "$PLAN" 2>/dev/null | head -1 | sed 's/^base-ref: *//')
+git diff --stat "$BASE_REF"...HEAD
+```
+
+若提交区间显示改动超过轻量阈值（> 4 个文件、跨模块协调、或 delta spec 超过 1 个 capability），手动设置为完整验证：
+
+```bash
+bash "$COMET_STATE" set <change-name> verify_mode full
+```
+
+### 1b. 验证失败决策（阻塞点）
+
+验证不通过时**必须使用 AskUserQuestion 工具暂停并等待用户决定修复或接受偏差**。不得自动运行 `bash "$COMET_STATE" transition <change-name> verify-fail`，也不得自动调用 `/comet-build`。禁止仅输出文字提示后继续执行。
+
+暂停时必须列出：
+- 失败项
+- 是否属于 CRITICAL（构建失败、测试失败、安全问题、核心验收场景失败）
+- 推荐处理方式
+
+**不确定性原则**：无法确定严重程度时，降级处理（SUGGESTION > WARNING > CRITICAL）。仅对构建失败、测试失败、安全问题使用 CRITICAL；模糊或不确定的问题标为 WARNING 或 SUGGESTION。
+
+用户选择后按以下方式继续：
+- **全部修复**：运行 `bash "$COMET_STATE" transition <change-name> verify-fail`，然后调用 `/comet-build` 修复
+- **逐项处理**：CRITICAL 失败项必须修复；非 CRITICAL 失败项可选择接受偏差，但必须在验证报告中记录接受原因和影响范围。若存在任何 CRITICAL 失败项，不允许跳过修复直接全部接受
+
+### 2a. 轻量验证（小改动）
+
+当规模评估结果为"小"时，跳过 `openspec-verify-change`，直接执行以下检查：
+
+1. tasks.md 全部任务已完成 `[x]`
+2. 改动文件与 tasks.md 描述一致（`git diff --stat` / `git diff --cached --stat` / `git diff --stat <base-ref>...HEAD` 对照 tasks 内容）
+3. 编译通过（执行项目对应的构建命令，如 `npm run build`、`mvn compile`、`cargo build` 等）
+4. 相关测试通过
+5. 无明显安全问题（无硬编码密钥、无新增 unsafe 操作）
+
+**通过标准**：5 项全部 OK，无 CRITICAL 问题。
+
+**不通过时**：报告失败项，进入 Step 1b 的验证失败决策阻塞点。用户选择修复后，才执行以下命令记录失败并回退到 build 阶段，然后调用 `/comet-build` 修复：
+
+```bash
+# 仅在用户确认修复后执行
+bash "$COMET_STATE" transition <change-name> verify-fail
+```
+
+**报告格式**：简表列出 5 项检查结果 + PASS/FAIL。
+
+**跳过项**（不在轻量验证中检查）：
+- spec scenario 覆盖率
+- design doc 一致性深度比对
+- code pattern consistency 建议
+- delta spec 与 design doc 漂移检测
+
+### 2b. 完整验证（大改动）
+
+当规模评估结果为"大"时：
+
+**立即执行：** 使用 Skill 工具加载 `openspec-verify-change` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引验证。检查项：
+1. tasks.md 全部任务已完成（`[x]`）
+2. 实现符合 `openspec/changes/<name>/design.md` 高层设计决策
+3. 实现符合 Design Doc（`docs/superpowers/specs/` 下的技术设计文档）
+4. 能力规格场景全部通过
+5. proposal.md 目标已满足
+6. delta spec 与 design doc 无矛盾（若 Build 阶段有增量修改 spec，检查 design doc 是否有对应记录）
+7. `docs/superpowers/specs/` 关联的设计文档可定位（文件存在且与当前 change 相关）
+
+验证不通过时：报告缺失项，进入 Step 1b 的验证失败决策阻塞点。用户选择修复后，才执行以下命令记录失败并回退到 build 阶段，然后调用 `/comet-build` 补充：
+
+```bash
+# 仅在用户确认修复后执行
+bash "$COMET_STATE" transition <change-name> verify-fail
+```
+
+**Spec 漂移处理**（用户决策点）：
+- 若检查项 6 发现矛盾（delta spec 有内容但 design doc 未体现），**必须使用 AskUserQuestion 工具以单选题形式暂停并等待用户选择处理方式**，不得自动选择。选项：
+  - 选项 A：在 design doc 追加 "Implementation Divergence" 节记录偏差原因。选项 A 属于 verify 阶段允许产物；写入后不得因该 design doc 变更再次触发 Step 1b dirty-worktree 决策
+  - 选项 B：用户选择 B 后，运行 `bash "$COMET_STATE" transition <change-name> verify-fail`，然后调用 `/comet-build`；由 `/comet-build` 的 Spec 增量更新规则加载 `superpowers:brainstorming` 更新 Design Doc + delta spec
+  - 选项 C：确认偏差可接受，继续验证（归档时 design doc 将标记为 `superseded-by-main-spec`）
+
+### 3. 收尾（Superpowers）
+
+**立即执行：** 使用 Skill 工具加载 `superpowers:finishing-a-development-branch` 技能。禁止跳过此步骤。
+
+如 `superpowers:finishing-a-development-branch` 不可用，停止流程并提示安装或启用 Superpowers 技能，不要用普通对话替代该步骤。
+
+技能加载后，按其指引收尾。分支处理选项：
+1. 本地合并到主分支
+2. 推送并创建 PR
+3. 保持分支（稍后处理）
+4. 丢弃工作
+
+这是用户决策点。**必须使用 AskUserQuestion 工具暂停并等待用户选择分支处理方式**，不得根据推荐、默认值或当前分支状态自行选择。禁止仅输出文字提示后继续执行。只有在用户完成选择且对应操作完成后，才允许写入 `branch_status: handled`。
+
+**确认项**：
+- 全部测试通过
+- 无硬编码密钥或安全问题
+
+### 4. 记录验证证据
+
+验证报告必须落盘，并在 `.comet.yaml` 中记录；分支处理完成后也必须写入状态字段。不要手动设置 `verify_result: pass`，通过 guard 自动流转。
+
+```bash
+mkdir -p docs/superpowers/reports
+# 将本次验证结论写入报告文件，例如：
+# docs/superpowers/reports/YYYY-MM-DD-<change-name>-verify.md
+
+bash "$COMET_STATE" set <change-name> verification_report docs/superpowers/reports/YYYY-MM-DD-<change-name>-verify.md
+bash "$COMET_STATE" set <change-name> branch_status handled
+```
+
+## 退出条件
+
+- 验证报告通过
+- 分支已处理
+- `.comet.yaml` 中 `verification_report` 指向已存在的验证报告文件
+- `.comet.yaml` 中 `branch_status: handled`
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> verify --apply`，全部 PASS 后通过 `comet-state transition verify-pass` 自动流转到 `phase: archive`
+
+验证和分支处理均完成后，运行 guard 自动流转：
+
+```bash
+bash "$COMET_GUARD" <change-name> verify --apply
+```
+
+状态文件自动更新为 `phase: archive`、`verify_result: pass`、`verified_at: YYYY-MM-DD`。
+
+## 上下文压缩恢复
+
+Verify 阶段可能触发上下文压缩。恢复时先运行：
+
+```bash
+bash "$COMET_STATE" check <change-name> verify --recover
+```
+
+脚本输出结构化恢复上下文（phase、验证状态、分支状态、恢复动作），根据输出的 Recovery action 决定下一步。
+
+## 自动流转
+
+退出条件满足后（包括用户选择分支处理方式），自动流转到下一阶段：
+
+> **REQUIRED NEXT SKILL:** 调用 `comet-archive` skill 进入归档阶段。

+
+## 决策核心（Decision Core）
+
+agent 做决策只需读本节，参考附录按需查阅。
+
+### 阶段自动检测
+
+**Step 0: 活跃 Change 发现与意图判定**
+
+1. 先做 Preset 检测；命中 hotfix/tweak 时直接调用对应 preset skill，不进入普通 open 分支
+2. 未命中 preset 时，运行 `openspec list --json` 获取所有活跃 change
+
+**Preset 检测优先级最高**：
+- 用户明确描述为 bug fix / 热修复 + 满足 hotfix 条件 → 直接 `/comet-hotfix`
+- 用户明确描述为文案/配置/文档/prompt 小调整 + 满足 tweak 条件 → 直接 `/comet-tweak`
+- 未命中 preset → 按下表处理
+
+| 活跃 change | 用户输入 | 行为 |
+|-------------|---------|------|
+| 无 | 非 preset 输入 | → 调用 `/comet-open` |
+| 恰好 1 个 | `/comet <描述>` | → **询问**：继续该变更 or 创建新变更 |
+| 多个 | `/comet <描述>` | → **询问**：继续现有变更 or 创建新变更；若选继续 → 列出清单让用户选择 |
+| 恰好 1 个 | `/comet`（无描述） | → 自动选中，进入 Step 1 |
+| 多个 | `/comet`（无描述） | → 列出清单让用户选择 |
+
+<IMPORTANT>
+当用户选择「创建新变更」时，**必须调用 `/comet-open`**（禁止直接调用 `/opsx:new`）。
+`/comet-open` 负责完整双初始化：OpenSpec artifacts（由内部 `/opsx:new` 创建）+ `.comet.yaml` 状态文件。
+直接调用 `/opsx:new` 会缺失 `.comet.yaml`，导致后续阶段判定失败。
+</IMPORTANT>
+
+**Step 1: 读取 `.comet.yaml` 状态元数据**
+
+优先读取 `openspec/changes/<name>/.comet.yaml`。不存在时回退到 `openspec status --change "<name>" --json`、`tasks.md` 和 `docs/superpowers/` 文件检查。
+
+**断点恢复规则**：
+- 每次恢复上下文时，先重新执行 Step 0 和 Step 1，不依赖对话历史判断阶段
+- 只要存在 active change 且工作区有未提交改动，必须按 `comet/reference/dirty-worktree.md` 协议处理。该协议定义了检查步骤、归因分类和禁令，本文件不重复
+- 若 `phase: build`，先检查 `build_mode` 和 `isolation` 是否已设置；若有未设置的字段，回到 `/comet-build` 对应步骤补充后再执行；若均已设置，读取 tasks.md 的下一个未勾选任务继续
+- 若 `phase: verify` 且 `verify_result: fail`，进入验证失败决策阻塞点：暂停并询问用户修复或接受偏差；用户选择修复后才运行 `bash "$COMET_STATE" transition <name> verify-fail` 并调用 `/comet-build`
+- 若 `phase: open` 但 proposal/design/tasks 已完整，先运行 `bash "$COMET_GUARD" <change-name> open --apply` 修正状态，再继续判定
+- 若 `phase: archive`，只允许调用 `/comet-archive`；归档成功后 change 会移动到 archive 目录，不再对原活跃目录运行 guard
+
+**Step 2: 阶段判定**（按顺序，命中即停）
+
+1. `archived: true` 或 change 已移入 archive → 流程已完成
+2. `verify_result: pass` 且 `archived` 不是 `true` → `/comet-archive`
+3. `verify_result: fail` → 进入验证失败决策阻塞点（暂停询问修复或接受偏差；用户选择修复后才 `verify-fail` 并 `/comet-build`）
+4. `phase: verify` 或 tasks.md 全部勾选 → `/comet-verify`
+5. `phase: build` 或已有 Design Doc 但计划/执行未完成 → 优先按 workflow 路由：`hotfix` → `/comet-hotfix`，`tweak` → `/comet-tweak`，`full` → `/comet-build`
+6. `phase: design` 或有 change 但无 Design Doc → `/comet-design`
+7. `phase: open` 或有活跃 change 但 `.comet.yaml` 缺失 → `/comet-open`
+8. 无活跃 change → `/comet-open`
+
+如果元数据与文件状态冲突，以文件状态为准，修正 `.comet.yaml` 后继续。
+
+### 预设升级条件
+
+**hotfix → full**（满足任一即升级）：
+- 改动涉及 **3+ 文件**
+- 涉及架构变更（新模块、新接口、新依赖）
+- 涉及数据库 schema 变更
+- 修复引入新的 public API
+- 修复范围超出单一函数/模块
+
+**tweak → full**（满足任一即升级）：
+- 改动涉及 **5+ 文件**
+- 涉及多个模块的协调修改
+- 需要新增测试用例 **5+**
+- 涉及配置项的新增或删除（非值修改）
+
+### 错误处理速查
+
+| 场景 | 处理方式 |
+|------|---------|
+| `openspec list --json` 失败 | 检查 openspec 是否已安装，提示 `openspec init` |
+| 子 skill 不可用 | 停止流程，提示安装或启用对应 skill |
+| `.comet.yaml` 格式异常或缺失 | 以文件状态为准，用 `bash $COMET_STATE set` 修正后继续 |
+| 构建/测试失败 | 返回 build 阶段修复，不进入 verify |
+| change 目录结构不完整 | 按 `comet-open` 产物要求补齐 |
+
+### 阶段衔接
+
+<IMPORTANT>
+单次 `/comet` 调用从检测到的阶段开始，退出条件满足后进入下一阶段。
+
+流转链：open → design → build → verify → archive
+
+**连续执行要求**：从检测到的阶段开始，agent 自动推进后续阶段。但**自动推进仅适用于没有用户决策的衔接点**。遇到用户决策点时，**必须使用 AskUserQuestion 工具暂停并等待用户明确回复**，不得用推荐规则、默认值或历史偏好代替用户确认，也不得仅输出文字提示后继续执行。
+
+**决策点是阻塞点**：只要到达下列任一节点，当前 `/comet` 调用必须停住，**使用 AskUserQuestion 工具等待用户选择**。用户明确选择后才能写入对应状态字段、执行对应操作，随后再继续自动流转。
+
+需要用户参与的节点（仅在这些节点暂停）：
+1. open 阶段 proposal/design/tasks 审视确认
+2. brainstorming 确认设计方案
+3. build 阶段选择工作方式（隔离方式 + 执行方式，一次交互完成）
+4. verify 不通过时决定修复或接受偏差（含 Spec 漂移处理方式选择）
+5. finishing-branch 选择分支处理方式
+6. 遇到升级条件（hotfix/tweak → 完整流程）
+7. build 阶段范围扩张需重新设计或拆分新 change
+
+agent 不应跳过这些决策点；其他明确无歧义的阶段衔接必须自动继续推进，不得中途退出。到达决策点时，**禁止以文字输出代替工具等待——必须通过 AskUserQuestion 明确获取用户选择后才能继续**。
+
+**红旗清单** — 以下想法出现时立即停止并检查：
+
+| Agent 心理 | 实际风险 |
+|-----------|---------|
+| "用户应该会同意这个方案" | 不能替用户决策，用 AskUserQuestion |
+| "这只是个小改动，不需要确认" | 决策点无大小之分，阻塞点必须等待 |
+| "用户之前选过 A，这次也选 A" | 历史偏好不能替代当前确认 |
+| "我已经解释了方案，用户没反对" | 没反对 ≠ 同意，必须用工具获取明确选择 |
+| "流程走到这里应该没问题了" | 验证不通过 ≠ 通过，检查 verify_result |
+</IMPORTANT>

+
+### .comet.yaml 字段说明
+
+```yaml
+workflow: full
+phase: build
+design_doc: docs/superpowers/specs/YYYY-MM-DD-topic-design.md
+plan: docs/superpowers/plans/YYYY-MM-DD-feature.md
+base_ref: a1b2c3d4e5f6...
+build_mode: subagent-driven-development
+isolation: branch
+verify_mode: light
+verify_result: pending
+verification_report: null
+branch_status: pending
+created_at: 2026-05-26
+verified_at: null
+archived: false
+```
+
+| 字段 | 含义 |
+|------|------|
+| `workflow` | `full`、`hotfix` 或 `tweak` |
+| `phase` | 当前阶段：`open`、`design`、`build`、`verify`、`archive`（init 统一设为 `open`，guard 负责过渡） |
+| `design_doc` | 关联的 Superpowers Design Doc 路径，可为空 |
+| `plan` | 关联的 Superpowers Plan 路径，可为空 |
+| `base_ref` | init 时记录的 git commit SHA，用于 scale 评估。无 plan 时作为改动文件数统计基准 |
+| `build_mode` | 已选择的执行方式，可为空 |
+| `isolation` | `branch` 或 `worktree`，工作区隔离方式。full 初始化可为 `null`，但只允许持续到 `/comet-build` Step 3 前；hotfix/tweak 默认 `branch` |
+| `verify_mode` | `light` 或 `full`，可为空 |
+| `verify_result` | `pending`、`pass` 或 `fail` |
+| `verification_report` | 验证报告文件路径，verify 通过前必须指向已存在文件 |
+| `branch_status` | `pending` 或 `handled`，分支处理完成后设为 `handled` |
+| `created_at` | change 创建日期（init 时自动写入），格式 `YYYY-MM-DD` |
+| `verified_at` | 验证通过时间，可为空 |
+| `archived` | change 是否已归档 |
+
+可选字段：
+
+| 字段 | 含义 |
+|------|------|
+| `direct_override` | `true`/`false`。full workflow 如需使用 `build_mode: direct`，必须显式设为 `true` |
+| `build_command` | 项目构建命令。guard 优先运行该命令，失败时打印命令输出 |
+| `verify_command` | 项目验证命令。verify guard 优先运行该命令，未配置时回退到构建命令 |
+
+状态机硬约束：
+- `build → verify` 前，`isolation` 必须是 `branch` 或 `worktree`
+- `build → verify` 前，`build_mode` 必须已选择
+- `build_mode: direct` 默认只允许 `hotfix` / `tweak`；full workflow 需要 `direct_override: true`
+- 这些约束同时存在于 `comet-guard.sh build --apply` 和 `comet-state.sh transition <name> build-complete`
+
+### 脚本定位
+
+Comet 脚本随 skill 包分发在 `comet/scripts/` 下。**不硬编码路径** — 定位一次，缓存到环境变量：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+
+# 脚本定位失败时停止流程
+if [ -z "$COMET_GUARD" ] || [ -z "$COMET_STATE" ] || [ -z "$COMET_HANDOFF" ] || [ -z "$COMET_ARCHIVE" ]; then
+  echo "ERROR: Comet scripts not found. Ensure the comet skill is installed." >&2
+  echo "Expected path pattern: */comet/scripts/comet-*.sh under project or platform skill directories" >&2
+  return 1
+fi
+```
+
+**自动状态更新**：guard 支持 `--apply` 参数，验证通过后自动更新 `.comet.yaml` 状态字段：
+
+```bash
+bash "$COMET_GUARD" <change-name> <phase> --apply
+```
+
+`--apply` 内部委托给 `comet-state transition`。需要直接表达状态事件时使用：
+
+```bash
+bash "$COMET_STATE" transition <change-name> open-complete
+bash "$COMET_STATE" transition <change-name> design-complete
+bash "$COMET_STATE" transition <change-name> build-complete
+bash "$COMET_STATE" transition <change-name> verify-pass
+bash "$COMET_STATE" transition <change-name> verify-fail
+bash "$COMET_STATE" transition <archive-name> archived
+```
+
+**归档脚本**：一键完成归档全部步骤：
+
+```bash
+bash "$COMET_ARCHIVE" <change-name>
+```
+
+加载 comet 后，agent 应执行以上变量赋值一次，后续全程复用 `$COMET_GUARD`、`$COMET_STATE`、`$COMET_HANDOFF`、`$COMET_ARCHIVE`。
+
+### 文件结构

+```
+
+### 最佳实践
+
+1. **brainstorming 不可跳过** — 每次变更必须经过深度设计（hotfix 和 tweak 除外）
+2. **delta spec 是活文档** — 阶段 3 期间可自由修改，归档时同步
+3. **交接包由脚本生成** — OpenSpec → Superpowers 的上下文必须通过 `comet-handoff.sh` 生成 compact 可追溯摘录（必要时 `--full`），并由 guard 校验 source/hash/mode
+4. **保持 tasks.md 同步** — 完成一个勾一个
+5. **频繁提交** — 每个任务一次提交，message 体现设计意图
+6. **先验证再归档** — `/comet-verify` 通过后才执行 `/comet-archive`
+7. **增量更新分级** — 小编辑、中重 brainstorming、大新 change
+8. **Plan 必须关联 change** — 文件头包含 `change:` 和 `design-doc:` 元数据
+9. **归档闭环** — design doc 和 plan 必须标注 `archived-with` 状态
+10. **修改已有功能** — 直接 open 新 change 即可
+11. **Preset 有上限** — hotfix/tweak 满足升级条件时及时切换到完整流程

+# Dirty Worktree 协议
+
+规范路径：`comet/reference/dirty-worktree.md`
+
+本协议由所有涉及代码修改的 comet 子 skill 共享。当 agent 恢复上下文或继续执行时，必须按本协议处理未提交的工作区改动。
+
+## 1. 检查步骤
+
+继续或开始修改前，必须先运行以下命令：
+
+```bash
+git status --short
+git diff --stat
+git diff --cached --stat
+git ls-files --others --exclude-standard
+```
+
+必要时再查看 `git diff` / `git diff --cached` / 新建文件内容。
+
+## 2. 核心规则
+
+- 用户可能不会说明自己改了哪里。只要存在 dirty worktree（包括 Git 状态里显示为 `??` 的新建文件），就先假设改动可能来自用户或混合来源
+- dirty worktree 只代表代码事实，不会自动推进 `.comet.yaml` 的 `phase` 或勾选 `tasks.md`；只有完成归因、验证、同步必要文档，并通过对应阶段 guard 后，才允许推进 Comet 状态
+
+## 3. 归因分类
+
+将 dirty diff 分为三类：
+
+1. **属于当前 change**：文件和内容能对应当前 change 的目标、tasks.md、plan 或 delta spec。将其纳入当前任务继续，不重复改同一处
+2. **不属于当前 change**：文件或内容与当前目标无关。暂停并询问用户：并入当前 change、拆成新 change、保留不处理，或明确授权丢弃
+3. **来源不确定**：无法从 diff 和文档判断归属。暂停并向用户汇报文件列表和判断依据，不继续推进阶段
+
+## 4. 常见处理模式
+
+### 已实现但 tasks.md 未勾选
+
+先验证实现（运行构建和测试），通过后补勾任务。不要因为任务未勾选就重做一遍，也不要因为状态文件滞后而忽略代码事实。若当前子 skill 定义了阶段特例，以子 skill 为准。
+
+### 暗示计划或范围已变化
+
+按当前子 skill 的升级、增量更新或回退规则处理，本协议不重复阶段特例。
+
+### 模糊恢复意图
+
+用户说"继续""接着跑""我改了一点""刚才不满意""重新弄""代码动过""先按现在的来"等模糊恢复意图时，按本协议处理。不要要求用户先回忆具体改了哪里。
+
+### open/design 阶段出现代码改动
+
+若当前仍处于 `open` 或 `design`，但 dirty worktree 已经包含代码改动，先按本协议归因，不要直接推进阶段：
+
+- 属于当前 change 的改动：作为需求或设计输入记录到 proposal/design/spec/design doc/tasks 中；进入 build 前仍需完成对应阶段 guard
+- 不属于当前 change 或来源不确定：暂停询问用户是并入当前 change、拆成新 change、保留不处理，还是明确授权丢弃
+- 禁止在 open/design 阶段直接把代码改动当作已完成实现并推进到 verify
+
+## 5. 禁令
+
+- 禁止在未理解 dirty diff 来源时覆盖、回滚、格式化重写或忽略用户改动
+- 禁止在 dirty diff 未解释清楚时判定验证通过

+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+
+Archive multiple completed changes in a single operation.
+
+This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
+
+**Input**: None required (prompts for selection)
+
+**Steps**
+
+1. **Get active changes**
+
+   Run `openspec list --json` to get all active changes.
+
+   If no active changes exist, inform user and stop.
+
+2. **Prompt for change selection**
+
+   Use **AskUserQuestion tool** with multi-select to let user choose changes:
+   - Show each change with its schema
+   - Include an option for "All changes"
+   - Allow any number of selections (1+ works, 2+ is the typical use case)
+
+   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
+
+3. **Batch validation - gather status for all selected changes**
+
+   For each selected change, collect:
+
+   a. **Artifact status** - Run `openspec status --change "<name>" --json`
+      - Parse `schemaName` and `artifacts` list
+      - Note which artifacts are `done` vs other states
+
+   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
+      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
+      - If no tasks file exists, note as "No tasks"
+
+   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
+      - List which capability specs exist
+      - For each, extract requirement names (lines matching `### Requirement: <name>`)
+
+4. **Detect spec conflicts**
+
+   Build a map of `capability -> [changes that touch it]`:
+
+   ```
+   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
+   api  -> [change-c]            <- OK (only 1 change)
+   ```
+
+   A conflict exists when 2+ selected changes have delta specs for the same capability.
+
+5. **Resolve conflicts agentically**
+
+   **For each conflict**, investigate the codebase:
+
+   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
+
+   b. **Search the codebase** for implementation evidence:
+      - Look for code implementing requirements from each delta spec
+      - Check for related files, functions, or tests
+
+   c. **Determine resolution**:
+      - If only one change is actually implemented -> sync that one's specs
+      - If both implemented -> apply in chronological order (older first, newer overwrites)
+      - If neither implemented -> skip spec sync, warn user
+
+   d. **Record resolution** for each conflict:
+      - Which change's specs to apply
+      - In what order (if both)
+      - Rationale (what was found in codebase)
+
+6. **Show consolidated status table**
+
+   Display a table summarizing all changes:
+
+   ```
+   | Change              | Artifacts | Tasks | Specs   | Conflicts | Status |
+   |---------------------|-----------|-------|---------|-----------|--------|
+   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
+   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
+   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
+   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
+   ```
+
+   For conflicts, show the resolution:
+   ```
+   * Conflict resolution:
+     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
+   ```
+
+   For incomplete changes, show warnings:
+   ```
+   Warnings:
+   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
+   ```
+
+7. **Confirm batch operation**
+
+   Use **AskUserQuestion tool** with a single confirmation:
+
+   - "Archive N changes?" with options based on status
+   - Options might include:
+     - "Archive all N changes"
+     - "Archive only N ready changes (skip incomplete)"
+     - "Cancel"
+
+   If there are incomplete changes, make clear they'll be archived with warnings.
+
+8. **Execute archive for each confirmed change**
+
+   Process changes in the determined order (respecting conflict resolution):
+
+   a. **Sync specs** if delta specs exist:
+      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
+      - For conflicts, apply in resolved order
+      - Track if sync was done
+
+   b. **Perform the archive**:

+      - Skipped: user chose not to archive (if applicable)
+

+   ## Bulk Archive Complete
+
+   Archived 3 changes:
+   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
+   - project-config -> archive/2026-01-19-project-config/
+   - add-oauth -> archive/2026-01-19-add-oauth/
+
+   Skipped 1 change:
+   - add-verify-skill (user chose not to archive incomplete)
+
+   Spec sync summary:
+   - 4 delta specs synced to main specs
+   - 1 conflict resolved (auth: applied both in chronological order)
+   ```
+
+   If any failures:
+   ```
+   Failed 1 change:
+   - some-change: Archive directory already exists
+   ```
+
+**Conflict Resolution Examples**
+
+Example 1: Only one implemented
+```
+Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
+
+Checking add-oauth:
+- Delta adds "OAuth Provider Integration" requirement
+- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
+
+Checking add-jwt:
+- Delta adds "JWT Token Handling" requirement
+- Searching codebase... no JWT implementation found
+
+Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
+```
+
+Example 2: Both implemented
+```
+Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
+
+Checking add-rest-api (created 2026-01-10):
+- Delta adds "REST Endpoints" requirement
+- Searching codebase... found src/api/rest.ts
+
+Checking add-graphql (created 2026-01-15):
+- Delta adds "GraphQL Schema" requirement
+- Searching codebase... found src/api/graphql.ts
+
+Resolution: Both implemented. Will apply add-rest-api specs first,
+then add-graphql specs (chronological order, newer takes precedence).
+```
+
+**Output On Success**
+
+```
+## Bulk Archive Complete
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+- <change-2> -> archive/YYYY-MM-DD-<change-2>/
+
+Spec sync summary:
+- N delta specs synced to main specs
+- No conflicts (or: M conflicts resolved)
+```
+
+**Output On Partial Success**
+
+```
+## Bulk Archive Complete (partial)
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+
+Skipped M changes:
+- <change-2> (user chose not to archive incomplete)
+
+Failed K changes:
+- <change-3>: Archive directory already exists
+```
+
+**Output When No Changes**
+
+```
+## No Changes to Archive
+
+No active changes found. Create a new change to get started.
+```
+
+**Guardrails**
+- Allow any number of changes (1+ is fine, 2+ is the typical use case)
+- Always prompt for selection, never auto-select
+- Detect spec conflicts early and resolve by checking codebase
+- When both changes are implemented, apply specs in chronological order
+- Skip spec sync only when implementation is missing (warn user)
+- Show clear per-change status before confirming
+- Use single confirmation for entire batch
+- Track and report all outcomes (success/skip/fail)
+- Preserve .openspec.yaml when moving to archive
+- Archive directory target uses current date: YYYY-MM-DD-<name>
+- If archive target exists, fail that change but continue with others

+
+Continue working on a change by creating the next artifact.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
+
+   Present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Schema (from `schema` field if present, otherwise "spec-driven")
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check current status**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
+   - `isComplete`: Boolean indicating if all artifacts are complete
+
+3. **Act based on status**:
+
+   ---
+
+   **If all artifacts are complete (`isComplete: true`)**:
+   - Congratulate the user
+   - Show final status including the schema used
+   - Suggest: "All artifacts created! You can now implement this change or archive it."
+   - STOP
+
+   ---
+
+   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
+   - Pick the FIRST artifact with `status: "ready"` from the status output
+   - Get its instructions:
+     ```bash
+     openspec instructions <artifact-id> --change "<name>" --json
+     ```
+   - Parse the JSON. The key fields are:
+     - `context`: Project background (constraints for you - do NOT include in output)
+     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+     - `template`: The structure to use for your output file
+     - `instruction`: Schema-specific guidance
+     - `outputPath`: Where to write the artifact
+     - `dependencies`: Completed artifacts to read for context
+   - **Create the artifact file**:
+     - Read any completed dependency files for context
+     - Use `template` as the structure - fill in its sections
+     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
+     - Write to the output path specified in instructions
+   - Show what was created and what's now unlocked
+   - STOP after creating ONE artifact
+
+   ---
+
+   **If no artifacts are ready (all blocked)**:
+   - This shouldn't happen with a valid schema
+   - Show status and suggest checking for issues
+
+4. **After creating an artifact, show progress**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After each invocation, show:
+- Which artifact was created
+- Schema workflow being used
+- Current progress (N/M complete)
+- What artifacts are now unlocked
+- Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
+
+**Artifact Creation Guidelines**
+
+The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
+
+Common artifact patterns:
+
+**spec-driven schema** (proposal → specs → design → tasks):
+- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
+  - The Capabilities section is critical - each capability listed will need a spec file.
+- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
+- **design.md**: Document technical decisions, architecture, and implementation approach.
+- **tasks.md**: Break down implementation into checkboxed tasks.
+
+For other schemas, follow the `instruction` field from the CLI output.
+
+**Guardrails**
+- Create ONE artifact per invocation
+- Always read dependency artifacts before creating a new one
+- Never skip artifacts or create out of order
+- If context is unclear, ask the user before creating
+- Verify the artifact file exists after writing before marking progress
+- Use the schema's artifact sequence, don't assume specific artifact names
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output

+description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.3.1"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+

+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+
+Fast-forward through artifact creation - generate everything needed to start implementation in one go.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "✓ Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+

+
+Start a new change using the experimental artifact-driven approach.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Determine the workflow schema**
+
+   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user mentions:**
+   - A specific schema name → use `--schema <name>`
+   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
+
+   **Otherwise**: Omit `--schema` to use the default.
+
+3. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   Add `--schema <name>` only if the user requested a specific workflow.
+   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
+
+4. **Show the artifact status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+   This shows which artifacts need to be created and which are ready (dependencies satisfied).
+
+5. **Get instructions for the first artifact**
+   The first artifact depends on the schema (e.g., `proposal` for spec-driven).
+   Check the status output to find the first artifact with status "ready".
+   ```bash
+   openspec instructions <first-artifact-id> --change "<name>"
+   ```
+   This outputs the template and context for creating the first artifact.
+
+6. **STOP and wait for user direction**
+
+**Output**
+
+After completing the steps, summarize:
+- Change name and location
+- Schema/workflow being used and its artifact sequence
+- Current status (0/N artifacts complete)
+- The template for the first artifact
+- Prompt: "Ready to create the first artifact? Just describe what this change is about and I'll draft it, or ask me to continue."
+
+**Guardrails**
+- Do NOT create any artifacts yet - just show the instructions
+- Do NOT advance beyond showing the first artifact template
+- If the name is invalid (not kebab-case), ask for a valid name
+- If a change with that name already exists, suggest continuing that change instead
+- Pass --schema if using a non-default workflow

+description: Guided onboarding for OpenSpec - walk through a complete workflow cycle with narration and real codebase work.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.3.1"
+---
+
+Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
+
+---
+
+## Preflight
+
+Before starting, check if the OpenSpec CLI is installed:
+
+```bash
+# Unix/macOS
+openspec --version 2>&1 || echo "CLI_NOT_INSTALLED"
+# Windows (PowerShell)
+# if (Get-Command openspec -ErrorAction SilentlyContinue) { openspec --version } else { echo "CLI_NOT_INSTALLED" }
+```
+
+**If CLI not installed:**
+> OpenSpec CLI is not installed. Install it first, then come back to `/opsx:onboard`.
+
+Stop here if not installed.
+
+---
+
+## Phase 1: Welcome
+
+Display:
+
+```
+## Welcome to OpenSpec!
+
+I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
+
+**What we'll do:**
+1. Pick a small, real task in your codebase
+2. Explore the problem briefly
+3. Create a change (the container for our work)
+4. Build the artifacts: proposal → specs → design → tasks
+5. Implement the tasks
+6. Archive the completed change
+
+**Time:** ~15-20 minutes
+
+Let's start by finding something to work on.
+```
+
+---
+
+## Phase 2: Task Selection
+
+### Codebase Analysis
+
+Scan the codebase for small improvement opportunities. Look for:
+
+1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
+2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
+3. **Functions without tests** - Cross-reference `src/` with test directories
+4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
+5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
+6. **Missing validation** - User input handlers without validation
+
+Also check recent git activity:
+```bash
+# Unix/macOS
+git log --oneline -10 2>/dev/null || echo "No git history"
+# Windows (PowerShell)
+# git log --oneline -10 2>$null; if ($LASTEXITCODE -ne 0) { echo "No git history" }
+```
+
+### Present Suggestions
+
+From your analysis, present 3-4 specific suggestions:
+
+```
+## Task Suggestions
+
+Based on scanning your codebase, here are some good starter tasks:
+
+**1. [Most promising task]**
+   Location: `src/path/to/file.ts:42`
+   Scope: ~1-2 files, ~20-30 lines
+   Why it's good: [brief reason]
+
+**2. [Second task]**
+   Location: `src/another/file.ts`
+   Scope: ~1 file, ~15 lines
+   Why it's good: [brief reason]
+
+**3. [Third task]**
+   Location: [location]
+   Scope: [estimate]
+   Why it's good: [brief reason]
+
+**4. Something else?**
+   Tell me what you'd like to work on.
+
+Which task interests you? (Pick a number or describe your own)
+```
+
+**If nothing found:** Fall back to asking what the user wants to build:
+> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
+
+### Scope Guardrail
+
+If the user picks or describes something too large (major feature, multi-day work):
+
+```
+That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
+
+For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
+
+**Options:**
+1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
+2. **Pick something else** - One of the other suggestions, or a different small task?
+3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
+
+What would you prefer?
+```
+
+Let the user override if they insist—this is a soft guardrail.
+
+---
+
+## Phase 3: Explore Demo
+
+Once a task is selected, briefly demonstrate explore mode:
+
+```
+Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
+```
+
+Spend 1-2 minutes investigating the relevant code:
+- Read the file(s) involved
+- Draw a quick ASCII diagram if it helps
+- Note any considerations
+
+```
+## Quick Exploration
+
+[Your brief analysis—what you found, any considerations]
+
+┌─────────────────────────────────────────┐
+│   [Optional: ASCII diagram if helpful]  │
+└─────────────────────────────────────────┘
+
+Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
+
+Now let's create a change to hold our work.
+```
+
+**PAUSE** - Wait for user acknowledgment before proceeding.
+
+---
+
+## Phase 4: Create the Change
+
+**EXPLAIN:**
+```
+## Creating a Change
+
+A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
+
+Let me create one for our task.
+```
+
+**DO:** Create the change with a derived kebab-case name:
+```bash
+openspec new change "<derived-name>"
+```
+
+**SHOW:**
+```
+Created: `openspec/changes/<name>/`
+
+The folder structure:
+```
+openspec/changes/<name>/
+├── proposal.md    ← Why we're doing this (empty, we'll fill it)
+├── design.md      ← How we'll build it (empty)
+├── specs/         ← Detailed requirements (empty)
+└── tasks.md       ← Implementation checklist (empty)
+```
+
+Now let's fill in the first artifact—the proposal.
+```
+
+---
+
+## Phase 5: Proposal
+
+**EXPLAIN:**
+```
+## The Proposal
+
+The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
+
+I'll draft one based on our task.
+```
+
+**DO:** Draft the proposal content (don't save yet):
+
+```
+Here's a draft proposal:
+
+---
+
+## Why
+
+[1-2 sentences explaining the problem/opportunity]
+
+## What Changes
+
+[Bullet points of what will be different]
+
+## Capabilities
+
+### New Capabilities
+- `<capability-name>`: [brief description]
+
+### Modified Capabilities
+<!-- If modifying existing behavior -->
+
+## Impact
+
+- `src/path/to/file.ts`: [what changes]
+- [other files if applicable]
+
+---
+
+Does this capture the intent? I can adjust before we save it.
+```
+
+**PAUSE** - Wait for user approval/feedback.
+
+After approval, save the proposal:
+```bash
+openspec instructions proposal --change "<name>" --json
+```
+Then write the content to `openspec/changes/<name>/proposal.md`.
+
+```
+Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
+
+Next up: specs.
+```
+
+---
+
+## Phase 6: Specs
+
+**EXPLAIN:**
+```
+## Specs
+
+Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
+
+For a small task like this, we might only need one spec file.
+```
+
+**DO:** Create the spec file:
+```bash
+# Unix/macOS
+mkdir -p openspec/changes/<name>/specs/<capability-name>
+# Windows (PowerShell)
+# New-Item -ItemType Directory -Force -Path "openspec/changes/<name>/specs/<capability-name>"
+```
+
+Draft the spec content:
+
+```
+Here's the spec:
+
+---
+
+## ADDED Requirements
+
+### Requirement: <Name>
+
+<Description of what the system should do>
+
+#### Scenario: <Scenario name>
+
+- **WHEN** <trigger condition>
+- **THEN** <expected outcome>
+- **AND** <additional outcome if needed>
+
+---
+
+This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
+```
+
+Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
+
+---
+
+## Phase 7: Design
+
+**EXPLAIN:**
+```
+## Design
+
+The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
+
+For small changes, this might be brief. That's fine—not every change needs deep design discussion.
+```
+
+**DO:** Draft design.md:
+
+```
+Here's the design:
+
+---
+
+## Context
+
+[Brief context about the current state]
+
+## Goals / Non-Goals
+
+**Goals:**
+- [What we're trying to achieve]
+
+**Non-Goals:**
+- [What's explicitly out of scope]
+
+## Decisions
+
+### Decision 1: [Key decision]
+
+[Explanation of approach and rationale]
+
+---
+
+For a small task, this captures the key decisions without over-engineering.
+```
+
+Save to `openspec/changes/<name>/design.md`.
+
+---
+
+## Phase 8: Tasks
+
+**EXPLAIN:**
+```
+## Tasks
+
+Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
+
+These should be small, clear, and in logical order.
+```
+
+**DO:** Generate tasks based on specs and design:
+
+```
+Here are the implementation tasks:
+
+---
+
+## 1. [Category or file]
+
+- [ ] 1.1 [Specific task]
+- [ ] 1.2 [Specific task]
+
+## 2. Verify
+
+- [ ] 2.1 [Verification step]
+
+---
+
+Each checkbox becomes a unit of work in the apply phase. Ready to implement?
+```
+
+**PAUSE** - Wait for user to confirm they're ready to implement.
+
+Save to `openspec/changes/<name>/tasks.md`.
+
+---
+
+## Phase 9: Apply (Implementation)
+
+**EXPLAIN:**
+```
+## Implementation
+
+Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
+```
+
+**DO:** For each task:
+
+1. Announce: "Working on task N: [description]"
+2. Implement the change in the codebase
+3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
+4. Mark complete in tasks.md: `- [ ]` → `- [x]`
+5. Brief status: "✓ Task N complete"
+
+Keep narration light—don't over-explain every line of code.
+
+After all tasks:
+
+```
+## Implementation Complete
+
+All tasks done:
+- [x] Task 1
+- [x] Task 2
+- [x] ...
+
+The change is implemented! One more step—let's archive it.
+```
+
+---
+
+## Phase 10: Archive
+
+**EXPLAIN:**
+```
+## Archiving
+
+When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
+
+Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
+```
+
+**DO:**
+```bash
+openspec archive "<name>"
+```
+
+**SHOW:**
+```
+Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
+
+The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
+```
+
+---
+
+## Phase 11: Recap & Next Steps
+
+```
+## Congratulations!
+
+You just completed a full OpenSpec cycle:
+
+1. **Explore** - Thought through the problem
+2. **New** - Created a change container
+3. **Proposal** - Captured WHY
+4. **Specs** - Defined WHAT in detail
+5. **Design** - Decided HOW
+6. **Tasks** - Broke it into steps
+7. **Apply** - Implemented the work
+8. **Archive** - Preserved the record
+
+This same rhythm works for any size change—a small fix or a major feature.

+
+## Graceful Exit Handling
+
+### User wants to stop mid-way
+
+If the user says they need to stop, want to pause, or seem disengaged:
+
+```
+No problem! Your change is saved at `openspec/changes/<name>/`.
+
+To pick up where we left off later:
+- `/opsx:continue <name>` - Resume artifact creation
+- `/opsx:apply <name>` - Jump to implementation (if tasks exist)
+
+The work won't be lost. Come back whenever you're ready.
+```
+
+Exit gracefully without pressure.
+
+### User just wants command reference
+
+If the user says they just want to see the commands or skip the tutorial:

+
+## Guardrails
+
+- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
+- **Keep narration light** during implementation—teach without lecturing
+- **Don't skip phases** even if the change is small—the goal is teaching the workflow
+- **Pause for acknowledgment** at marked points, but don't over-pause
+- **Handle exits gracefully**—never pressure the user to continue
+- **Use real codebase tasks**—don't simulate or use fake examples
+- **Adjust scope gently**—guide toward smaller tasks but respect user choice

+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Find delta specs**
+
+   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+3. **For each delta spec, apply changes to main specs**
+
+   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+4. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+description: Verify implementation matches change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.3.1"
+---
+
+Verify that an implementation matches the change artifacts (specs, tasks, design).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have implementation tasks (tasks artifact exists).
+   Include the schema used for each change if available.
+   Mark changes with incomplete tasks as "(In Progress)".
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifacts exist for this change
+
+3. **Get the change directory and load artifacts**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns the change directory and `contextFiles` (artifact ID -> array of concrete file paths). Read all available artifacts from `contextFiles`.
+
+4. **Initialize verification report structure**
+
+   Create a report structure with three dimensions:
+   - **Completeness**: Track tasks and spec coverage
+   - **Correctness**: Track requirement implementation and scenario coverage
+   - **Coherence**: Track design adherence and pattern consistency
+
+   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
+
+5. **Verify Completeness**
+
+   **Task Completion**:
+   - If `contextFiles.tasks` exists, read every file path in it
+   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
+   - Count complete vs total tasks
+   - If incomplete tasks exist:
+     - Add CRITICAL issue for each incomplete task
+     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
+
+   **Spec Coverage**:
+   - If delta specs exist in `openspec/changes/<name>/specs/`:
+     - Extract all requirements (marked with "### Requirement:")
+     - For each requirement:
+       - Search codebase for keywords related to the requirement
+       - Assess if implementation likely exists
+     - If requirements appear unimplemented:
+       - Add CRITICAL issue: "Requirement not found: <requirement name>"
+       - Recommendation: "Implement requirement X: <description>"
+
+6. **Verify Correctness**
+
+   **Requirement Implementation Mapping**:
+   - For each requirement from delta specs:
+     - Search codebase for implementation evidence
+     - If found, note file paths and line ranges
+     - Assess if implementation matches requirement intent
+     - If divergence detected:
+       - Add WARNING: "Implementation may diverge from spec: <details>"
+       - Recommendation: "Review <file>:<lines> against requirement X"
+
+   **Scenario Coverage**:
+   - For each scenario in delta specs (marked with "#### Scenario:"):
+     - Check if conditions are handled in code
+     - Check if tests exist covering the scenario
+     - If scenario appears uncovered:
+       - Add WARNING: "Scenario not covered: <scenario name>"
+       - Recommendation: "Add test or implementation for scenario: <description>"
+
+7. **Verify Coherence**
+
+   **Design Adherence**:
+   - If `contextFiles.design` exists:
+     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
+     - Verify implementation follows those decisions
+     - If contradiction detected:
+       - Add WARNING: "Design decision not followed: <decision>"
+       - Recommendation: "Update implementation or revise design.md to match reality"
+   - If no design.md: Skip design adherence check, note "No design.md to verify against"
+
+   **Code Pattern Consistency**:
+   - Review new code for consistency with project patterns
+   - Check file naming, directory structure, coding style
+   - If significant deviations found:
+     - Add SUGGESTION: "Code pattern deviation: <details>"
+     - Recommendation: "Consider following project pattern: <example>"
+
+8. **Generate Verification Report**
+
+   **Summary Scorecard**:
+   ```
+   ## Verification Report: <change-name>
+
+   ### Summary
+   | Dimension    | Status           |
+   |--------------|------------------|
+   | Completeness | X/Y tasks, N reqs|
+   | Correctness  | M/N reqs covered |
+   | Coherence    | Followed/Issues  |
+   ```
+
+   **Issues by Priority**:
+
+   1. **CRITICAL** (Must fix before archive):
+      - Incomplete tasks
+      - Missing requirement implementations
+      - Each with specific, actionable recommendation
+
+   2. **WARNING** (Should fix):
+      - Spec/design divergences
+      - Missing scenario coverage
+      - Each with specific recommendation
+
+   3. **SUGGESTION** (Nice to fix):
+      - Pattern inconsistencies
+      - Minor improvements
+      - Each with specific recommendation
+
+   **Final Assessment**:
+   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
+   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
+   - If all clear: "All checks passed. Ready for archive."
+
+**Verification Heuristics**
+
+- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
+- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
+- **Coherence**: Look for glaring inconsistencies, don't nitpick style
+- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
+- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
+
+**Graceful Degradation**
+
+- If only tasks.md exists: verify task completion only, skip spec/design checks
+- If tasks + specs exist: verify completeness and correctness, skip design
+- If full artifacts: verify all three dimensions
+- Always note which checks were skipped and why
+
+**Output Format**
+
+Use clear markdown with:
+- Table for summary scorecard
+- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
+- Code references in format: `file.ts:123`
+- Specific, actionable recommendations
+- No vague suggestions like "consider reviewing"

+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name (e.g., `/opsx-apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx-apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx-continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx-archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name after `/opsx-archive` (e.g., `/opsx-archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** openspec/changes/archive/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Archive multiple completed changes at once
+---
+
+Archive multiple completed changes in a single operation.
+
+This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
+
+**Input**: None required (prompts for selection)
+**Provided arguments**: $@
+
+**Steps**
+
+1. **Get active changes**
+
+   Run `openspec list --json` to get all active changes.
+
+   If no active changes exist, inform user and stop.
+
+2. **Prompt for change selection**
+
+   Use **AskUserQuestion tool** with multi-select to let user choose changes:
+   - Show each change with its schema
+   - Include an option for "All changes"
+   - Allow any number of selections (1+ works, 2+ is the typical use case)
+
+   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
+
+3. **Batch validation - gather status for all selected changes**
+
+   For each selected change, collect:
+
+   a. **Artifact status** - Run `openspec status --change "<name>" --json`
+      - Parse `schemaName` and `artifacts` list
+      - Note which artifacts are `done` vs other states
+
+   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
+      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
+      - If no tasks file exists, note as "No tasks"
+
+   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
+      - List which capability specs exist
+      - For each, extract requirement names (lines matching `### Requirement: <name>`)
+
+4. **Detect spec conflicts**
+
+   Build a map of `capability -> [changes that touch it]`:
+
+   ```
+   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
+   api  -> [change-c]            <- OK (only 1 change)
+   ```
+
+   A conflict exists when 2+ selected changes have delta specs for the same capability.
+
+5. **Resolve conflicts agentically**
+
+   **For each conflict**, investigate the codebase:
+
+   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
+
+   b. **Search the codebase** for implementation evidence:
+      - Look for code implementing requirements from each delta spec
+      - Check for related files, functions, or tests
+
+   c. **Determine resolution**:
+      - If only one change is actually implemented -> sync that one's specs
+      - If both implemented -> apply in chronological order (older first, newer overwrites)
+      - If neither implemented -> skip spec sync, warn user
+
+   d. **Record resolution** for each conflict:
+      - Which change's specs to apply
+      - In what order (if both)
+      - Rationale (what was found in codebase)
+
+6. **Show consolidated status table**
+
+   Display a table summarizing all changes:
+
+   ```
+   | Change              | Artifacts | Tasks | Specs   | Conflicts | Status |
+   |---------------------|-----------|-------|---------|-----------|--------|
+   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |

+   ```
+
+   For conflicts, show the resolution:
+   ```
+   * Conflict resolution:
+     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
+   ```
+
+   For incomplete changes, show warnings:
+   ```
+   Warnings:
+   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
+   ```
+
+7. **Confirm batch operation**
+
+   Use **AskUserQuestion tool** with a single confirmation:
+
+   - "Archive N changes?" with options based on status
+   - Options might include:
+     - "Archive all N changes"
+     - "Archive only N ready changes (skip incomplete)"
+     - "Cancel"
+
+   If there are incomplete changes, make clear they'll be archived with warnings.
+
+8. **Execute archive for each confirmed change**
+
+   Process changes in the determined order (respecting conflict resolution):
+
+   a. **Sync specs** if delta specs exist:
+      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
+      - For conflicts, apply in resolved order
+      - Track if sync was done
+
+   b. **Perform the archive**:
+      ```bash
+      mkdir -p openspec/changes/archive
+      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+      ```
+
+   c. **Track outcome** for each change:
+      - Success: archived successfully
+      - Failed: error during archive (record error)
+      - Skipped: user chose not to archive (if applicable)
+
+9. **Display summary**
+
+   Show final results:
+
+   ```
+   ## Bulk Archive Complete
+
+   Archived 3 changes:
+   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
+   - project-config -> archive/2026-01-19-project-config/
+   - add-oauth -> archive/2026-01-19-add-oauth/
+
+   Skipped 1 change:
+   - add-verify-skill (user chose not to archive incomplete)
+
+   Spec sync summary:
+   - 4 delta specs synced to main specs
+   - 1 conflict resolved (auth: applied both in chronological order)
+   ```
+
+   If any failures:
+   ```
+   Failed 1 change:
+   - some-change: Archive directory already exists
+   ```
+
+**Conflict Resolution Examples**
+
+Example 1: Only one implemented
+```
+Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
+
+Checking add-oauth:
+- Delta adds "OAuth Provider Integration" requirement
+- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
+
+Checking add-jwt:
+- Delta adds "JWT Token Handling" requirement
+- Searching codebase... no JWT implementation found
+
+Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
+```
+
+Example 2: Both implemented
+```
+Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
+
+Checking add-rest-api (created 2026-01-10):
+- Delta adds "REST Endpoints" requirement
+- Searching codebase... found src/api/rest.ts
+
+Checking add-graphql (created 2026-01-15):
+- Delta adds "GraphQL Schema" requirement
+- Searching codebase... found src/api/graphql.ts
+
+Resolution: Both implemented. Will apply add-rest-api specs first,
+then add-graphql specs (chronological order, newer takes precedence).
+```
+
+**Output On Success**
+
+```
+## Bulk Archive Complete
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+- <change-2> -> archive/YYYY-MM-DD-<change-2>/
+
+Spec sync summary:
+- N delta specs synced to main specs
+- No conflicts (or: M conflicts resolved)
+```
+
+**Output On Partial Success**
+
+```
+## Bulk Archive Complete (partial)
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+
+Skipped M changes:
+- <change-2> (user chose not to archive incomplete)
+
+Failed K changes:
+- <change-3>: Archive directory already exists
+```
+
+**Output When No Changes**
+
+```
+## No Changes to Archive
+
+No active changes found. Create a new change to get started.
+```
+
+**Guardrails**
+- Allow any number of changes (1+ is fine, 2+ is the typical use case)
+- Always prompt for selection, never auto-select
+- Detect spec conflicts early and resolve by checking codebase
+- When both changes are implemented, apply specs in chronological order
+- Skip spec sync only when implementation is missing (warn user)
+- Show clear per-change status before confirming
+- Use single confirmation for entire batch
+- Track and report all outcomes (success/skip/fail)
+- Preserve .openspec.yaml when moving to archive
+- Archive directory target uses current date: YYYY-MM-DD-<name>
+- If archive target exists, fail that change but continue with others

+
+Continue working on a change by creating the next artifact.
+
+**Input**: Optionally specify a change name after `/opsx-continue` (e.g., `/opsx-continue add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
+
+   Present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Schema (from `schema` field if present, otherwise "spec-driven")
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check current status**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
+   - `isComplete`: Boolean indicating if all artifacts are complete
+
+3. **Act based on status**:
+
+   ---
+
+   **If all artifacts are complete (`isComplete: true`)**:
+   - Congratulate the user
+   - Show final status including the schema used
+   - Suggest: "All artifacts created! You can now implement this change with `/opsx-apply` or archive it with `/opsx-archive`."
+   - STOP
+
+   ---
+
+   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
+   - Pick the FIRST artifact with `status: "ready"` from the status output
+   - Get its instructions:
+     ```bash
+     openspec instructions <artifact-id> --change "<name>" --json
+     ```
+   - Parse the JSON. The key fields are:
+     - `context`: Project background (constraints for you - do NOT include in output)
+     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+     - `template`: The structure to use for your output file
+     - `instruction`: Schema-specific guidance
+     - `outputPath`: Where to write the artifact
+     - `dependencies`: Completed artifacts to read for context
+   - **Create the artifact file**:
+     - Read any completed dependency files for context
+     - Use `template` as the structure - fill in its sections
+     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
+     - Write to the output path specified in instructions
+   - Show what was created and what's now unlocked
+   - STOP after creating ONE artifact
+
+   ---
+
+   **If no artifacts are ready (all blocked)**:
+   - This shouldn't happen with a valid schema
+   - Show status and suggest checking for issues
+
+4. **After creating an artifact, show progress**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After each invocation, show:
+- Which artifact was created
+- Schema workflow being used
+- Current progress (N/M complete)
+- What artifacts are now unlocked
+- Prompt: "Run `/opsx-continue` to create the next artifact"
+
+**Artifact Creation Guidelines**
+
+The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
+
+Common artifact patterns:
+
+**spec-driven schema** (proposal → specs → design → tasks):
+- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
+  - The Capabilities section is critical - each capability listed will need a spec file.
+- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
+- **design.md**: Document technical decisions, architecture, and implementation approach.
+- **tasks.md**: Break down implementation into checkboxed tasks.
+
+For other schemas, follow the `instruction` field from the CLI output.
+
+**Guardrails**
+- Create ONE artifact per invocation
+- Always read dependency artifacts before creating a new one
+- Never skip artifacts or create out of order
+- If context is unclear, ask the user before creating
+- Verify the artifact file exists after writing before marking progress
+- Use the schema's artifact sequence, don't assume specific artifact names
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output

+description: "Enter explore mode - think through ideas, investigate problems, clarify requirements"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Input**: The argument after `/opsx-explore` is whatever the user wants to think about. Could be:
+**Provided arguments**: $@
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+---
+
+Fast-forward through artifact creation - generate everything needed to start implementation.
+
+**Input**: The argument after `/opsx-ff` is the change name (kebab-case), OR a description of what the user wants to build.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:

+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "✓ Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx-apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one

+Start a new change using the experimental artifact-driven approach.
+
+**Input**: The argument after `/opsx-new` is the change name (kebab-case), OR a description of what the user wants to build.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."

+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Determine the workflow schema**
+
+   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user mentions:**
+   - A specific schema name → use `--schema <name>`
+   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
+
+   **Otherwise**: Omit `--schema` to use the default.
+
+3. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   Add `--schema <name>` only if the user requested a specific workflow.
+   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
+
+4. **Show the artifact status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+   This shows which artifacts need to be created and which are ready (dependencies satisfied).
+
+5. **Get instructions for the first artifact**
+   The first artifact depends on the schema. Check the status output to find the first artifact with status "ready".
+   ```bash
+   openspec instructions <first-artifact-id> --change "<name>"
+   ```
+   This outputs the template and context for creating the first artifact.
+
+6. **STOP and wait for user direction**
+
+**Output**
+
+After completing the steps, summarize:
+- Change name and location
+- Schema/workflow being used and its artifact sequence
+- Current status (0/N artifacts complete)
+- The template for the first artifact
+- Prompt: "Ready to create the first artifact? Run `/opsx-continue` or just describe what this change is about and I'll draft it."
+
+**Guardrails**
+- Do NOT create any artifacts yet - just show the instructions
+- Do NOT advance beyond showing the first artifact template
+- If the name is invalid (not kebab-case), ask for a valid name
+- If a change with that name already exists, suggest using `/opsx-continue` instead
+- Pass --schema if using a non-default workflow

+## Preflight
+
+Before starting, check if the OpenSpec CLI is installed:
+
+```bash
+# Unix/macOS
+openspec --version 2>&1 || echo "CLI_NOT_INSTALLED"
+# Windows (PowerShell)
+# if (Get-Command openspec -ErrorAction SilentlyContinue) { openspec --version } else { echo "CLI_NOT_INSTALLED" }

+
+**If CLI not installed:**
+> OpenSpec CLI is not installed. Install it first, then come back to `/opsx-onboard`.
+

+## Phase 1: Welcome
+
+Display:
+
+```
+## Welcome to OpenSpec!
+
+I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
+
+**What we'll do:**
+1. Pick a small, real task in your codebase
+2. Explore the problem briefly
+3. Create a change (the container for our work)
+4. Build the artifacts: proposal → specs → design → tasks
+5. Implement the tasks
+6. Archive the completed change
+
+**Time:** ~15-20 minutes
+
+Let's start by finding something to work on.
+```
+
+---
+
+## Phase 2: Task Selection
+
+### Codebase Analysis
+
+Scan the codebase for small improvement opportunities. Look for:
+
+1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
+2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
+3. **Functions without tests** - Cross-reference `src/` with test directories
+4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
+5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
+6. **Missing validation** - User input handlers without validation
+
+Also check recent git activity:
+```bash
+# Unix/macOS
+git log --oneline -10 2>/dev/null || echo "No git history"
+# Windows (PowerShell)
+# git log --oneline -10 2>$null; if ($LASTEXITCODE -ne 0) { echo "No git history" }
+```
+
+### Present Suggestions
+
+From your analysis, present 3-4 specific suggestions:
+
+```
+## Task Suggestions
+
+Based on scanning your codebase, here are some good starter tasks:
+
+**1. [Most promising task]**
+   Location: `src/path/to/file.ts:42`
+   Scope: ~1-2 files, ~20-30 lines
+   Why it's good: [brief reason]
+
+**2. [Second task]**
+   Location: `src/another/file.ts`
+   Scope: ~1 file, ~15 lines
+   Why it's good: [brief reason]
+
+**3. [Third task]**
+   Location: [location]
+   Scope: [estimate]
+   Why it's good: [brief reason]
+
+**4. Something else?**
+   Tell me what you'd like to work on.
+
+Which task interests you? (Pick a number or describe your own)
+```
+
+**If nothing found:** Fall back to asking what the user wants to build:
+> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
+
+### Scope Guardrail
+
+If the user picks or describes something too large (major feature, multi-day work):
+
+```
+That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
+
+For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
+
+**Options:**
+1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
+2. **Pick something else** - One of the other suggestions, or a different small task?
+3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
+
+What would you prefer?
+```
+
+Let the user override if they insist—this is a soft guardrail.
+
+---
+
+## Phase 3: Explore Demo
+
+Once a task is selected, briefly demonstrate explore mode:
+
+```
+Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
+```
+
+Spend 1-2 minutes investigating the relevant code:
+- Read the file(s) involved
+- Draw a quick ASCII diagram if it helps
+- Note any considerations
+
+```
+## Quick Exploration
+
+[Your brief analysis—what you found, any considerations]
+
+┌─────────────────────────────────────────┐
+│   [Optional: ASCII diagram if helpful]  │
+└─────────────────────────────────────────┘
+
+Explore mode (`/opsx-explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
+
+Now let's create a change to hold our work.
+```
+
+**PAUSE** - Wait for user acknowledgment before proceeding.
+
+---
+
+## Phase 4: Create the Change
+
+**EXPLAIN:**
+```
+## Creating a Change
+
+A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
+
+Let me create one for our task.
+```
+
+**DO:** Create the change with a derived kebab-case name:
+```bash
+openspec new change "<derived-name>"
+```
+
+**SHOW:**
+```
+Created: `openspec/changes/<name>/`
+
+The folder structure:
+```
+openspec/changes/<name>/
+├── proposal.md    ← Why we're doing this (empty, we'll fill it)
+├── design.md      ← How we'll build it (empty)
+├── specs/         ← Detailed requirements (empty)
+└── tasks.md       ← Implementation checklist (empty)
+```
+
+Now let's fill in the first artifact—the proposal.
+```
+
+---
+
+## Phase 5: Proposal
+
+**EXPLAIN:**
+```
+## The Proposal
+
+The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
+
+I'll draft one based on our task.
+```
+
+**DO:** Draft the proposal content (don't save yet):
+
+```
+Here's a draft proposal:
+
+---
+
+## Why
+
+[1-2 sentences explaining the problem/opportunity]
+
+## What Changes
+
+[Bullet points of what will be different]
+
+## Capabilities
+
+### New Capabilities
+- `<capability-name>`: [brief description]
+
+### Modified Capabilities
+<!-- If modifying existing behavior -->
+
+## Impact
+
+- `src/path/to/file.ts`: [what changes]
+- [other files if applicable]
+
+---
+
+Does this capture the intent? I can adjust before we save it.
+```
+
+**PAUSE** - Wait for user approval/feedback.
+
+After approval, save the proposal:
+```bash
+openspec instructions proposal --change "<name>" --json
+```
+Then write the content to `openspec/changes/<name>/proposal.md`.
+
+```
+Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
+
+Next up: specs.
+```
+
+---
+
+## Phase 6: Specs
+
+**EXPLAIN:**
+```
+## Specs
+
+Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
+
+For a small task like this, we might only need one spec file.
+```
+
+**DO:** Create the spec file:
+```bash
+# Unix/macOS
+mkdir -p openspec/changes/<name>/specs/<capability-name>
+# Windows (PowerShell)
+# New-Item -ItemType Directory -Force -Path "openspec/changes/<name>/specs/<capability-name>"
+```
+
+Draft the spec content:
+
+```
+Here's the spec:
+
+---
+
+## ADDED Requirements
+
+### Requirement: <Name>
+
+<Description of what the system should do>
+
+#### Scenario: <Scenario name>
+
+- **WHEN** <trigger condition>
+- **THEN** <expected outcome>
+- **AND** <additional outcome if needed>
+
+---
+
+This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
+```
+
+Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
+
+---
+
+## Phase 7: Design
+
+**EXPLAIN:**
+```
+## Design
+
+The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
+
+For small changes, this might be brief. That's fine—not every change needs deep design discussion.
+```
+
+**DO:** Draft design.md:
+
+```
+Here's the design:
+
+---
+
+## Context
+
+[Brief context about the current state]
+
+## Goals / Non-Goals
+
+**Goals:**
+- [What we're trying to achieve]
+
+**Non-Goals:**
+- [What's explicitly out of scope]
+
+## Decisions
+
+### Decision 1: [Key decision]
+
+[Explanation of approach and rationale]
+
+---
+
+For a small task, this captures the key decisions without over-engineering.
+```
+
+Save to `openspec/changes/<name>/design.md`.
+
+---
+
+## Phase 8: Tasks
+
+**EXPLAIN:**
+```
+## Tasks
+
+Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
+
+These should be small, clear, and in logical order.
+```
+
+**DO:** Generate tasks based on specs and design:
+
+```
+Here are the implementation tasks:
+
+---
+
+## 1. [Category or file]
+
+- [ ] 1.1 [Specific task]
+- [ ] 1.2 [Specific task]
+
+## 2. Verify
+
+- [ ] 2.1 [Verification step]
+
+---
+
+Each checkbox becomes a unit of work in the apply phase. Ready to implement?
+```
+
+**PAUSE** - Wait for user to confirm they're ready to implement.
+
+Save to `openspec/changes/<name>/tasks.md`.
+
+---
+
+## Phase 9: Apply (Implementation)
+
+**EXPLAIN:**
+```
+## Implementation
+
+Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
+```
+
+**DO:** For each task:
+
+1. Announce: "Working on task N: [description]"
+2. Implement the change in the codebase
+3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
+4. Mark complete in tasks.md: `- [ ]` → `- [x]`
+5. Brief status: "✓ Task N complete"
+
+Keep narration light—don't over-explain every line of code.
+
+After all tasks:
+
+```
+## Implementation Complete
+
+All tasks done:
+- [x] Task 1
+- [x] Task 2
+- [x] ...
+
+The change is implemented! One more step—let's archive it.
+```
+
+---
+
+## Phase 10: Archive
+
+**EXPLAIN:**
+```
+## Archiving
+
+When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
+
+Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
+```
+
+**DO:**
+```bash
+openspec archive "<name>"
+```
+
+**SHOW:**
+```
+Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
+
+The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
+```
+
+---
+
+## Phase 11: Recap & Next Steps
+
+```
+## Congratulations!
+
+You just completed a full OpenSpec cycle:
+
+1. **Explore** - Thought through the problem
+2. **New** - Created a change container
+3. **Proposal** - Captured WHY
+4. **Specs** - Defined WHAT in detail
+5. **Design** - Decided HOW
+6. **Tasks** - Broke it into steps
+7. **Apply** - Implemented the work
+8. **Archive** - Preserved the record
+
+This same rhythm works for any size change—a small fix or a major feature.

+
+### User wants to stop mid-way
+
+If the user says they need to stop, want to pause, or seem disengaged:
+
+```
+No problem! Your change is saved at `openspec/changes/<name>/`.
+
+To pick up where we left off later:
+- `/opsx-continue <name>` - Resume artifact creation
+- `/opsx-apply <name>` - Jump to implementation (if tasks exist)
+
+The work won't be lost. Come back whenever you're ready.
+```
+
+Exit gracefully without pressure.

+## Guardrails
+
+- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
+- **Keep narration light** during implementation—teach without lecturing
+- **Don't skip phases** even if the change is small—the goal is teaching the workflow
+- **Pause for acknowledgment** at marked points, but don't over-pause
+- **Handle exits gracefully**—never pressure the user to continue
+- **Use real codebase tasks**—don't simulate or use fake examples
+- **Adjust scope gently**—guide toward smaller tasks but respect user choice

+When ready to implement, run /opsx-apply
+
+---
+
+**Input**: The argument after `/opsx-propose` is the change name (kebab-case), OR a description of what the user wants to build.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx-apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+description: Sync delta specs from a change to main specs
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name after `/opsx-sync` (e.g., `/opsx-sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Find delta specs**
+
+   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+3. **For each delta spec, apply changes to main specs**
+
+   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+4. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+**Input**: Optionally specify a change name after `/opsx-verify` (e.g., `/opsx-verify add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+**Provided arguments**: $@
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have implementation tasks (tasks artifact exists).
+   Include the schema used for each change if available.
+   Mark changes with incomplete tasks as "(In Progress)".
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifacts exist for this change
+
+3. **Get the change directory and load artifacts**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns the change directory and `contextFiles` (artifact ID -> array of concrete file paths). Read all available artifacts from `contextFiles`.
+
+4. **Initialize verification report structure**
+
+   Create a report structure with three dimensions:
+   - **Completeness**: Track tasks and spec coverage
+   - **Correctness**: Track requirement implementation and scenario coverage
+   - **Coherence**: Track design adherence and pattern consistency
+
+   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
+
+5. **Verify Completeness**
+
+   **Task Completion**:
+   - If `contextFiles.tasks` exists, read every file path in it
+   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
+   - Count complete vs total tasks
+   - If incomplete tasks exist:
+     - Add CRITICAL issue for each incomplete task
+     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
+
+   **Spec Coverage**:
+   - If delta specs exist in `openspec/changes/<name>/specs/`:
+     - Extract all requirements (marked with "### Requirement:")
+     - For each requirement:
+       - Search codebase for keywords related to the requirement
+       - Assess if implementation likely exists
+     - If requirements appear unimplemented:
+       - Add CRITICAL issue: "Requirement not found: <requirement name>"
+       - Recommendation: "Implement requirement X: <description>"
+
+6. **Verify Correctness**
+
+   **Requirement Implementation Mapping**:
+   - For each requirement from delta specs:
+     - Search codebase for implementation evidence
+     - If found, note file paths and line ranges
+     - Assess if implementation matches requirement intent
+     - If divergence detected:
+       - Add WARNING: "Implementation may diverge from spec: <details>"
+       - Recommendation: "Review <file>:<lines> against requirement X"
+
+   **Scenario Coverage**:
+   - For each scenario in delta specs (marked with "#### Scenario:"):
+     - Check if conditions are handled in code
+     - Check if tests exist covering the scenario
+     - If scenario appears uncovered:
+       - Add WARNING: "Scenario not covered: <scenario name>"
+       - Recommendation: "Add test or implementation for scenario: <description>"
+
+7. **Verify Coherence**
+
+   **Design Adherence**:
+   - If `contextFiles.design` exists:
+     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
+     - Verify implementation follows those decisions
+     - If contradiction detected:
+       - Add WARNING: "Design decision not followed: <decision>"
+       - Recommendation: "Update implementation or revise design.md to match reality"
+   - If no design.md: Skip design adherence check, note "No design.md to verify against"
+
+   **Code Pattern Consistency**:
+   - Review new code for consistency with project patterns
+   - Check file naming, directory structure, coding style
+   - If significant deviations found:
+     - Add SUGGESTION: "Code pattern deviation: <details>"
+     - Recommendation: "Consider following project pattern: <example>"
+
+8. **Generate Verification Report**
+
+   **Summary Scorecard**:
+   ```
+   ## Verification Report: <change-name>
+
+   ### Summary
+   | Dimension    | Status           |
+   |--------------|------------------|
+   | Completeness | X/Y tasks, N reqs|
+   | Correctness  | M/N reqs covered |
+   | Coherence    | Followed/Issues  |
+   ```
+
+   **Issues by Priority**:
+
+   1. **CRITICAL** (Must fix before archive):
+      - Incomplete tasks
+      - Missing requirement implementations
+      - Each with specific, actionable recommendation
+
+   2. **WARNING** (Should fix):
+      - Spec/design divergences
+      - Missing scenario coverage
+      - Each with specific recommendation
+
+   3. **SUGGESTION** (Nice to fix):
+      - Pattern inconsistencies
+      - Minor improvements
+      - Each with specific recommendation
+
+   **Final Assessment**:
+   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
+   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
+   - If all clear: "All checks passed. Ready for archive."
+
+**Verification Heuristics**
+
+- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
+- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
+- **Coherence**: Look for glaring inconsistencies, don't nitpick style
+- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
+- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
+
+**Graceful Degradation**
+
+- If only tasks.md exists: verify task completion only, skip spec/design checks
+- If tasks + specs exist: verify completeness and correctness, skip design
+- If full artifacts: verify all three dimensions
+- Always note which checks were skipped and why
+
+**Output Format**
+
+Use clear markdown with:
+- Table for summary scorecard
+- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
+- Code references in format: `file.ts:123`
+- Specific, actionable recommendations
+- No vague suggestions like "consider reviewing"

+name: brainstorming
+description: "You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation."
+---
+
+# Brainstorming Ideas Into Designs
+
+Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
+
+Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.
+
+<HARD-GATE>
+Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.
+</HARD-GATE>
+
+## Anti-Pattern: "This Is Too Simple To Need A Design"
+
+Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.
+
+## Checklist
+
+You MUST create a task for each of these items and complete them in order:
+
+1. **Explore project context** — check files, docs, recent commits
+2. **Offer visual companion** (if topic will involve visual questions) — this is its own message, not combined with a clarifying question. See the Visual Companion section below.
+3. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria
+4. **Propose 2-3 approaches** — with trade-offs and your recommendation
+5. **Present design** — in sections scaled to their complexity, get user approval after each section
+6. **Write design doc** — save to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md` and commit
+7. **Spec self-review** — quick inline check for placeholders, contradictions, ambiguity, scope (see below)
+8. **User reviews written spec** — ask user to review the spec file before proceeding
+9. **Transition to implementation** — invoke writing-plans skill to create implementation plan
+
+## Process Flow

+    "Spec self-review\n(fix inline)" -> "User reviews spec?";
+    "User reviews spec?" -> "Write design doc" [label="changes requested"];
+    "User reviews spec?" -> "Invoke writing-plans skill" [label="approved"];
+}
+```
+
+**The terminal state is invoking writing-plans.** Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.
+
+## The Process
+
+**Understanding the idea:**
+
+- Check out the current project state first (files, docs, recent commits)
+- Before asking detailed questions, assess scope: if the request describes multiple independent subsystems (e.g., "build a platform with chat, file storage, billing, and analytics"), flag this immediately. Don't spend questions refining details of a project that needs to be decomposed first.
+- If the project is too large for a single spec, help the user decompose into sub-projects: what are the independent pieces, how do they relate, what order should they be built? Then brainstorm the first sub-project through the normal design flow. Each sub-project gets its own spec → plan → implementation cycle.
+- For appropriately-scoped projects, ask questions one at a time to refine the idea
+- Prefer multiple choice questions when possible, but open-ended is fine too
+- Only one question per message - if a topic needs more exploration, break it into multiple questions
+- Focus on understanding: purpose, constraints, success criteria
+
+**Exploring approaches:**
+
+- Propose 2-3 different approaches with trade-offs
+- Present options conversationally with your recommendation and reasoning
+- Lead with your recommended option and explain why
+
+**Presenting the design:**
+
+- Once you believe you understand what you're building, present the design
+- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced
+- Ask after each section whether it looks right so far
+- Cover: architecture, components, data flow, error handling, testing
+- Be ready to go back and clarify if something doesn't make sense
+
+**Design for isolation and clarity:**
+
+- Break the system into smaller units that each have one clear purpose, communicate through well-defined interfaces, and can be understood and tested independently
+- For each unit, you should be able to answer: what does it do, how do you use it, and what does it depend on?
+- Can someone understand what a unit does without reading its internals? Can you change the internals without breaking consumers? If not, the boundaries need work.
+- Smaller, well-bounded units are also easier for you to work with - you reason better about code you can hold in context at once, and your edits are more reliable when files are focused. When a file grows large, that's often a signal that it's doing too much.
+
+**Working in existing codebases:**
+
+- Explore the current structure before proposing changes. Follow existing patterns.
+- Where existing code has problems that affect the work (e.g., a file that's grown too large, unclear boundaries, tangled responsibilities), include targeted improvements as part of the design - the way a good developer improves code they're working in.
+- Don't propose unrelated refactoring. Stay focused on what serves the current goal.
+
+## After the Design
+
+**Documentation:**
+
+- Write the validated design (spec) to `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md`
+  - (User preferences for spec location override this default)
+- Use elements-of-style:writing-clearly-and-concisely skill if available
+- Commit the design document to git
+
+**Spec Self-Review:**
+After writing the spec document, look at it with fresh eyes:
+
+1. **Placeholder scan:** Any "TBD", "TODO", incomplete sections, or vague requirements? Fix them.
+2. **Internal consistency:** Do any sections contradict each other? Does the architecture match the feature descriptions?
+3. **Scope check:** Is this focused enough for a single implementation plan, or does it need decomposition?
+4. **Ambiguity check:** Could any requirement be interpreted two different ways? If so, pick one and make it explicit.
+
+Fix any issues inline. No need to re-review — just fix and move on.
+
+**User Review Gate:**
+After the spec review loop passes, ask the user to review the written spec before proceeding:
+
+> "Spec written and committed to `<path>`. Please review it and let me know if you want to make any changes before we start writing out the implementation plan."
+
+Wait for the user's response. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves.
+
+**Implementation:**
+
+- Invoke the writing-plans skill to create a detailed implementation plan
+- Do NOT invoke any other skill. writing-plans is the next step.
+
+## Key Principles
+
+- **One question at a time** - Don't overwhelm with multiple questions
+- **Multiple choice preferred** - Easier to answer than open-ended when possible
+- **YAGNI ruthlessly** - Remove unnecessary features from all designs
+- **Explore alternatives** - Always propose 2-3 approaches before settling
+- **Incremental validation** - Present design, get approval before moving on
+- **Be flexible** - Go back and clarify when something doesn't make sense
+
+## Visual Companion
+
+A browser-based companion for showing mockups, diagrams, and visual options during brainstorming. Available as a tool — not a mode. Accepting the companion means it's available for questions that benefit from visual treatment; it does NOT mean every question goes through the browser.
+
+**Offering the companion:** When you anticipate that upcoming questions will involve visual content (mockups, layouts, diagrams), offer it once for consent:
+> "Some of what we're working on might be easier to explain if I can show it to you in a web browser. I can put together mockups, diagrams, comparisons, and other visuals as we go. This feature is still new and can be token-intensive. Want to try it? (Requires opening a local URL)"
+
+**This offer MUST be its own message.** Do not combine it with clarifying questions, context summaries, or any other content. The message should contain ONLY the offer above and nothing else. Wait for the user's response before continuing. If they decline, proceed with text-only brainstorming.
+
+**Per-question decision:** Even after the user accepts, decide FOR EACH QUESTION whether to use the browser or the terminal. The test: **would the user understand this better by seeing it than reading it?**
+
+- **Use the browser** for content that IS visual — mockups, wireframes, layout comparisons, architecture diagrams, side-by-side visual designs
+- **Use the terminal** for content that is text — requirements questions, conceptual choices, tradeoff lists, A/B/C/D text options, scope decisions
+
+A question about a UI topic is not automatically a visual question. "What does personality mean in this context?" is a conceptual question — use the terminal. "Which wizard layout works better?" is a visual question — use the browser.
+
+If they agree to the companion, read the detailed guide before proceeding:

+# Spec Document Reviewer Prompt Template
+
+Use this template when dispatching a spec document reviewer subagent.
+
+**Purpose:** Verify the spec is complete, consistent, and ready for implementation planning.
+
+**Dispatch after:** Spec document is written to docs/superpowers/specs/
+
+```
+Task tool (general-purpose):
+  description: "Review spec document"
+  prompt: |
+    You are a spec document reviewer. Verify this spec is complete and ready for planning.
+
+    **Spec to review:** [SPEC_FILE_PATH]
+
+    ## What to Check
+
+    | Category | What to Look For |
+    |----------|------------------|
+    | Completeness | TODOs, placeholders, "TBD", incomplete sections |
+    | Consistency | Internal contradictions, conflicting requirements |
+    | Clarity | Requirements ambiguous enough to cause someone to build the wrong thing |
+    | Scope | Focused enough for a single plan — not covering multiple independent subsystems |
+    | YAGNI | Unrequested features, over-engineering |
+
+    ## Calibration
+
+    **Only flag issues that would cause real problems during implementation planning.**
+    A missing section, a contradiction, or a requirement so ambiguous it could be
+    interpreted two different ways — those are issues. Minor wording improvements,
+    stylistic preferences, and "sections less detailed than others" are not.
+
+    Approve unless there are serious gaps that would lead to a flawed plan.
+
+    ## Output Format
+
+    ## Spec Review
+
+    **Status:** Approved | Issues Found
+
+    **Issues (if any):**
+    - [Section X]: [specific issue] - [why it matters for planning]
+
+    **Recommendations (advisory, do not block approval):**
+    - [suggestions for improvement]
+```

+# Visual Companion Guide
+
+Browser-based visual brainstorming companion for showing mockups, diagrams, and options.
+
+## When to Use
+
+Decide per-question, not per-session. The test: **would the user understand this better by seeing it than reading it?**
+
+**Use the browser** when the content itself is visual:
+
+- **UI mockups** — wireframes, layouts, navigation structures, component designs
+- **Architecture diagrams** — system components, data flow, relationship maps
+- **Side-by-side visual comparisons** — comparing two layouts, two color schemes, two design directions
+- **Design polish** — when the question is about look and feel, spacing, visual hierarchy
+- **Spatial relationships** — state machines, flowcharts, entity relationships rendered as diagrams
+
+**Use the terminal** when the content is text or tabular:
+
+- **Requirements and scope questions** — "what does X mean?", "which features are in scope?"
+- **Conceptual A/B/C choices** — picking between approaches described in words
+- **Tradeoff lists** — pros/cons, comparison tables
+- **Technical decisions** — API design, data modeling, architectural approach selection
+- **Clarifying questions** — anything where the answer is words, not a visual preference
+
+A question *about* a UI topic is not automatically a visual question. "What kind of wizard do you want?" is conceptual — use the terminal. "Which of these wizard layouts feels right?" is visual — use the browser.
+
+## How It Works
+
+The server watches a directory for HTML files and serves the newest one to the browser. You write HTML content to `screen_dir`, the user sees it in their browser and can click to select options. Selections are recorded to `state_dir/events` that you read on your next turn.
+
+**Content fragments vs full documents:** If your HTML file starts with `<!DOCTYPE` or `<html`, the server serves it as-is (just injects the helper script). Otherwise, the server automatically wraps your content in the frame template — adding the header, CSS theme, selection indicator, and all interactive infrastructure. **Write content fragments by default.** Only write full documents when you need complete control over the page.
+
+## Starting a Session
+
+```bash
+# Start server with persistence (mockups saved to project)
+scripts/start-server.sh --project-dir /path/to/project
+
+# Returns: {"type":"server-started","port":52341,"url":"http://localhost:52341",
+#           "screen_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/content",
+#           "state_dir":"/path/to/project/.superpowers/brainstorm/12345-1706000000/state"}
+```
+
+Save `screen_dir` and `state_dir` from the response. Tell user to open the URL.
+
+**Finding connection info:** The server writes its startup JSON to `$STATE_DIR/server-info`. If you launched the server in the background and didn't capture stdout, read that file to get the URL and port. When using `--project-dir`, check `<project>/.superpowers/brainstorm/` for the session directory.
+
+**Note:** Pass the project root as `--project-dir` so mockups persist in `.superpowers/brainstorm/` and survive server restarts. Without it, files go to `/tmp` and get cleaned up. Remind the user to add `.superpowers/` to `.gitignore` if it's not already there.
+
+**Launching the server by platform:**
+
+**Claude Code (macOS / Linux):**
+```bash
+# Default mode works — the script backgrounds the server itself
+scripts/start-server.sh --project-dir /path/to/project
+```
+
+**Claude Code (Windows):**
+```bash
+# Windows auto-detects and uses foreground mode, which blocks the tool call.
+# Use run_in_background: true on the Bash tool call so the server survives
+# across conversation turns.
+scripts/start-server.sh --project-dir /path/to/project
+```
+When calling this via the Bash tool, set `run_in_background: true`. Then read `$STATE_DIR/server-info` on the next turn to get the URL and port.
+
+**Codex:**
+```bash
+# Codex reaps background processes. The script auto-detects CODEX_CI and
+# switches to foreground mode. Run it normally — no extra flags needed.
+scripts/start-server.sh --project-dir /path/to/project
+```
+
+**Gemini CLI:**
+```bash
+# Use --foreground and set is_background: true on your shell tool call
+# so the process survives across turns
+scripts/start-server.sh --project-dir /path/to/project --foreground
+```
+
+**Other environments:** The server must keep running in the background across conversation turns. If your environment reaps detached processes, use `--foreground` and launch the command with your platform's background execution mechanism.
+
+If the URL is unreachable from your browser (common in remote/containerized setups), bind a non-loopback host:
+
+```bash
+scripts/start-server.sh \
+  --project-dir /path/to/project \
+  --host 0.0.0.0 \
+  --url-host localhost
+```
+
+Use `--url-host` to control what hostname is printed in the returned URL JSON.
+
+## The Loop
+
+1. **Check server is alive**, then **write HTML** to a new file in `screen_dir`:
+   - Before each write, check that `$STATE_DIR/server-info` exists. If it doesn't (or `$STATE_DIR/server-stopped` exists), the server has shut down — restart it with `start-server.sh` before continuing. The server auto-exits after 30 minutes of inactivity.
+   - Use semantic filenames: `platform.html`, `visual-style.html`, `layout.html`
+   - **Never reuse filenames** — each screen gets a fresh file
+   - Use Write tool — **never use cat/heredoc** (dumps noise into terminal)
+   - Server automatically serves the newest file
+
+2. **Tell user what to expect and end your turn:**
+   - Remind them of the URL (every step, not just first)
+   - Give a brief text summary of what's on screen (e.g., "Showing 3 layout options for the homepage")
+   - Ask them to respond in the terminal: "Take a look and let me know what you think. Click to select an option if you'd like."
+
+3. **On your next turn** — after the user responds in the terminal:
+   - Read `$STATE_DIR/events` if it exists — this contains the user's browser interactions (clicks, selections) as JSON lines
+   - Merge with the user's terminal text to get the full picture
+   - The terminal message is the primary feedback; `state_dir/events` provides structured interaction data
+
+4. **Iterate or advance** — if feedback changes current screen, write a new file (e.g., `layout-v2.html`). Only move to the next question when the current step is validated.
+
+5. **Unload when returning to terminal** — when the next step doesn't need the browser (e.g., a clarifying question, a tradeoff discussion), push a waiting screen to clear the stale content:
+
+   ```html
+   <!-- filename: waiting.html (or waiting-2.html, etc.) -->
+   <div style="display:flex;align-items:center;justify-content:center;min-height:60vh">
+     <p class="subtitle">Continuing in terminal...</p>
+   </div>
+   ```
+
+   This prevents the user from staring at a resolved choice while the conversation has moved on. When the next visual question comes up, push a new content file as usual.
+
+6. Repeat until done.
+
+## Writing Content Fragments
+
+Write just the content that goes inside the page. The server wraps it in the frame template automatically (header, theme CSS, selection indicator, and all interactive infrastructure).
+
+**Minimal example:**
+
+```html
+<h2>Which layout works better?</h2>
+<p class="subtitle">Consider readability and visual hierarchy</p>
+
+<div class="options">
+  <div class="option" data-choice="a" onclick="toggleSelect(this)">
+    <div class="letter">A</div>
+    <div class="content">
+      <h3>Single Column</h3>
+      <p>Clean, focused reading experience</p>
+    </div>
+  </div>
+  <div class="option" data-choice="b" onclick="toggleSelect(this)">
+    <div class="letter">B</div>
+    <div class="content">
+      <h3>Two Column</h3>
+      <p>Sidebar navigation with main content</p>
+    </div>
+  </div>
+</div>
+```
+
+That's it. No `<html>`, no CSS, no `<script>` tags needed. The server provides all of that.
+
+## CSS Classes Available
+
+The frame template provides these CSS classes for your content:
+
+### Options (A/B/C choices)
+
+```html
+<div class="options">
+  <div class="option" data-choice="a" onclick="toggleSelect(this)">
+    <div class="letter">A</div>
+    <div class="content">
+      <h3>Title</h3>
+      <p>Description</p>
+    </div>
+  </div>
+</div>
+```
+
+**Multi-select:** Add `data-multiselect` to the container to let users select multiple options. Each click toggles the item. The indicator bar shows the count.
+
+```html
+<div class="options" data-multiselect>
+  <!-- same option markup — users can select/deselect multiple -->
+</div>
+```
+
+### Cards (visual designs)
+
+```html
+<div class="cards">
+  <div class="card" data-choice="design1" onclick="toggleSelect(this)">
+    <div class="card-image"><!-- mockup content --></div>
+    <div class="card-body">
+      <h3>Name</h3>
+      <p>Description</p>
+    </div>
+  </div>
+</div>
+```
+
+### Mockup container
+
+```html
+<div class="mockup">
+  <div class="mockup-header">Preview: Dashboard Layout</div>
+  <div class="mockup-body"><!-- your mockup HTML --></div>
+</div>
+```
+
+### Split view (side-by-side)
+
+```html
+<div class="split">
+  <div class="mockup"><!-- left --></div>
+  <div class="mockup"><!-- right --></div>
+</div>
+```
+
+### Pros/Cons
+
+```html
+<div class="pros-cons">
+  <div class="pros"><h4>Pros</h4><ul><li>Benefit</li></ul></div>
+  <div class="cons"><h4>Cons</h4><ul><li>Drawback</li></ul></div>
+</div>
+```
+
+### Mock elements (wireframe building blocks)
+
+```html
+<div class="mock-nav">Logo | Home | About | Contact</div>
+<div style="display: flex;">
+  <div class="mock-sidebar">Navigation</div>
+  <div class="mock-content">Main content area</div>
+</div>
+<button class="mock-button">Action Button</button>
+<input class="mock-input" placeholder="Input field">
+<div class="placeholder">Placeholder area</div>
+```
+
+### Typography and sections
+
+- `h2` — page title
+- `h3` — section heading
+- `.subtitle` — secondary text below title
+- `.section` — content block with bottom margin
+- `.label` — small uppercase label text
+
+## Browser Events Format
+
+When the user clicks options in the browser, their interactions are recorded to `$STATE_DIR/events` (one JSON object per line). The file is cleared automatically when you push a new screen.
+
+```jsonl
+{"type":"click","choice":"a","text":"Option A - Simple Layout","timestamp":1706000101}
+{"type":"click","choice":"c","text":"Option C - Complex Grid","timestamp":1706000108}
+{"type":"click","choice":"b","text":"Option B - Hybrid","timestamp":1706000115}
+```
+
+The full event stream shows the user's exploration path — they may click multiple options before settling. The last `choice` event is typically the final selection, but the pattern of clicks can reveal hesitation or preferences worth asking about.
+
+If `$STATE_DIR/events` doesn't exist, the user didn't interact with the browser — use only their terminal text.
+
+## Design Tips
+
+- **Scale fidelity to the question** — wireframes for layout, polish for polish questions
+- **Explain the question on each page** — "Which layout feels more professional?" not just "Pick one"
+- **Iterate before advancing** — if feedback changes current screen, write a new version
+- **2-4 options max** per screen
+- **Use real content when it matters** — for a photography portfolio, use actual images (Unsplash). Placeholder content obscures design issues.
+- **Keep mockups simple** — focus on layout and structure, not pixel-perfect design
+
+## File Naming
+
+- Use semantic names: `platform.html`, `visual-style.html`, `layout.html`
+- Never reuse filenames — each screen must be a new file
+- For iterations: append version suffix like `layout-v2.html`, `layout-v3.html`
+- Server serves newest file by modification time
+
+## Cleaning Up
+
+```bash
+scripts/stop-server.sh $SESSION_DIR
+```
+
+If the session used `--project-dir`, mockup files persist in `.superpowers/brainstorm/` for later reference. Only `/tmp` sessions get deleted on stop.
+

+
+## 前置条件
+
+- 验证已通过（阶段 4 完成）
+- 分支已处理
+- `openspec/changes/<name>/.comet.yaml` 中 `verify_result: pass`
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+bash "$COMET_STATE" check <name> archive
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+### 1. 执行归档
+
+运行归档脚本，自动完成以下全部步骤：
+
+```bash
+bash "$COMET_ARCHIVE" "<change-name>"
+```
+
+脚本自动执行：
+1. 入口状态验证（phase=archive, verify_result=pass, archived=false）
+2. Delta spec 同步到主 spec
+3. Design doc 前置元数据标注（archived-with, status）
+4. Plan 前置元数据标注（archived-with）
+5. 移动 change 到归档目录
+6. 通过 `comet-state transition <archive-name> archived` 更新 `archived: true`
+
+如脚本返回非零退出码，报告错误并停止。
+如脚本返回零退出码，归档完成。
+脚本摘要中的 `X/Y steps succeeded` 以真实执行步骤计数，不会因 delta spec 同步或文档标注重复累计。
+
+当待同步的 delta spec 与已有主 spec 不一致时，脚本会在覆盖前打印 unified diff 预览，帮助确认归档同步内容。
+
+如需预览而不实际执行，使用 `--dry-run` 参数。
+
+### 2. 生命周期闭环
+
+Spec 生命周期在此完成：
+```
+brainstorming → delta spec → 实施 → 验证 → 主 spec 覆盖 → design doc 标注 → 归档
+```
+
+## 退出条件
+
+- 归档脚本执行成功（退出码 0）
+- 归档目录 `openspec/changes/archive/YYYY-MM-DD-<change-name>/` 存在
+- 归档后的 `.comet.yaml` 中 `archived: true`
+
+归档脚本会把 `openspec/changes/<name>/` 移动到 `openspec/changes/archive/YYYY-MM-DD-<name>/`。归档成功后**不要再对原 change 名运行** `bash "$COMET_GUARD" <change-name> archive`，因为原活跃目录已经不存在。归档完整性以脚本退出码和归档目录状态为准。
+
+## 完成
+
+Comet 流程全部完成。如需开始新工作，调用 `/comet` 或 `/comet-open`。

+
+- Design Doc 已创建（阶段 2 完成）
+- 活跃 change 存在
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash

+bash "$COMET_STATE" check <name> build
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：build 阶段所有操作可安全重复执行。读取 `.comet.yaml` 的 `phase` 字段确认仍在 build 阶段，读取 plan 文件头的 `base-ref`，再读取 tasks.md 找到第一个未勾选任务继续执行。已提交的任务不得重复提交。
+
+### 1. 制定计划
+
+**立即执行：** 使用 Skill 工具加载 `superpowers:writing-plans` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引制定计划。计划要求：
+- 保存至 `docs/superpowers/plans/YYYY-MM-DD-<feature>.md`
+- 引用设计文档，拆分为可执行任务
+- **Plan 文件头必须包含关联元数据**：
+
+```yaml
+---
+change: <openspec-change-name>
+design-doc: docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md
+base-ref: <git rev-parse HEAD before implementation>
+---
+```
+
+`base-ref` 用于验证阶段跨提交统计改动规模。创建计划时先记录当前提交：
+
+```bash
+git rev-parse HEAD
+```
+
+### 2. 更新计划状态
+
+先记录 plan 路径：
+
+```bash
+bash "$COMET_STATE" set <name> plan docs/superpowers/plans/YYYY-MM-DD-feature.md
+```
+
+无需手动更新 phase，guard 会在退出条件满足后自动流转。
+
+### 3. 选择工作方式
+
+计划已写入当前分支。在开始执行前，**一次性询问用户**选择工作区隔离方式和执行方式：
+
+**工作区隔离**：
+
+| 选项 | 方式 | 说明 |
+|------|------|------|
+| A | 创建分支 | 在当前仓库创建新分支，简单快速 |
+| B | 创建 Worktree | 隔离工作区，完全独立，适合并行开发 |
+
+**推荐规则**：
+- 变更涉及 ≤ 3 个文件 → 推荐 A
+- 需要并行开发、当前分支有未提交工作 → 推荐 B
+
+**执行方式**：
+
+| 选项 | 技能 | 适用场景 |
+|------|------|---------|
+| A | `superpowers:subagent-driven-development` | 任务独立、复杂度高、需要双阶段审查 |
+| B | `superpowers:executing-plans` | 任务简单、无子agent环境、轻量快速 |
+
+**执行方式推荐规则**：
+- 任务数 ≥ 3 → 推荐 A
+- 任务数 ≤ 2 且无跨模块依赖 → 推荐 B
+- 来自 hotfix 路径 → 推荐 B
+
+这是用户决策点。**必须使用 AskUserQuestion 工具暂停并等待用户明确选择隔离方式和执行方式**，不得根据推荐规则自行选择 `branch` 或 `worktree`，也不得根据推荐规则自行选择执行方式。推荐规则只能用于说明建议，不能替代用户确认。禁止仅输出文字提示后继续执行。
+
+用户选择后，更新 `isolation` 和 `build_mode` 字段：
+
+```bash
+bash "$COMET_STATE" set <name> isolation <branch|worktree>
+bash "$COMET_STATE" set <name> build_mode <subagent-driven-development|executing-plans|direct>
+```
+
+`isolation` 是脚本级硬约束。full workflow 初始化时可以为 `null`，但只允许存在到本步骤之前。若保持 `null`，`build → verify` 的 guard 和 `comet-state transition build-complete` 都会失败。
+
+`build_mode` 默认仅 hotfix/tweak preset 使用 `direct`。full workflow 不得默认使用 `direct`。只有用户明确要求跳过计划执行技能，且你已记录显式 override 时，才允许：
+
+```bash
+bash "$COMET_STATE" set <name> direct_override true
+bash "$COMET_STATE" set <name> build_mode direct
+```
+
+没有 `direct_override: true` 时，full workflow 的 `build_mode=direct` 会被 guard 和状态转换同时拦截。
+
+**执行隔离**：
+
+- **branch**：执行 `git checkout -b <change-name>`，后续工作在新分支上进行
+- **worktree**：必须使用 Skill 工具加载 `superpowers:using-git-worktrees` 技能创建隔离工作区。禁止用普通 shell 命令或原生工具绕过该技能；如该技能不可用，停止流程并提示安装或启用 Superpowers 技能。
+
+创建隔离后，确认计划文件可访问（分支方式天然可访问；worktree 方式需确认计划已提交）。
+
+**加载执行技能**：使用 Skill 工具加载对应技能。禁止跳过此步骤。
+
+如所选 Superpowers 技能不可用，停止流程并提示安装或启用对应技能，不要用普通对话替代该步骤。
+
+技能加载后，按其指引执行：
+- 按计划执行任务
+- 完成 tasks.md 勾选（`- [ ]` → `- [x]`）
+- 每个任务完成后提交代码
+
+### 4. Spec 增量更新
+
+实施过程中发现初版 spec 不完整时，按变更规模分级处理：
+
+| 规模 | 触发条件 | 做法 |
+|------|---------|------|
+| 小 | 遗漏验收场景、边界条件 | 直接编辑 delta spec + design.md，追加 tasks.md 任务 |
+| 中 | 接口变更、新增组件、数据流变化 | **使用 AskUserQuestion 工具暂停并等待用户确认后**，必须使用 Skill 工具加载 `superpowers:brainstorming` 更新 Design Doc + delta spec |
+| 大 | 全新 capability 需求 | **必须使用 AskUserQuestion 工具暂停并等待用户确认拆分**；用户确认后，通过 `/comet-open` 创建独立 change |
+
+**50% 阈值判定**：以 tasks.md 初始任务总数为基准，若新增任务数超过该总数的一半，视为超出原计划范围，**必须使用 AskUserQuestion 工具暂停并等待用户决定是否拆分为新 change**。
+
+创建独立 change 时必须调用 `/comet-open`，不得直接调用 `/opsx:new`。`/comet-open` 会同时创建 OpenSpec 产物和 `.comet.yaml`，避免新 change 脱离 Comet 状态机。
+
+**原则**：
+- delta spec 是活文档，本阶段期间随时可修改
+- 每次更新应提交，commit message 说明变更原因
+- 不提前同步到 main spec，归档时统一同步
+- 小规模增量直接改 delta spec 时，应在 commit message 中注明，便于归档时判断 design doc 漂移
+
+### 5. 上下文管理
+
+Build 是最长阶段，可能跨越大量任务。为支持上下文压缩后断点恢复：
+
+- **每完成一个 task**：立即勾选 tasks.md 并提交代码，确保 `.comet.yaml` 和文件状态持久化
+- **上下文压缩后恢复**：先运行 `bash "$COMET_STATE" check <change-name> build --recover`，脚本输出结构化恢复上下文（isolation/build_mode 状态、plan 路径、任务完成进度、恢复动作）。根据 Recovery action 决定下一步。
+- **用户手动修改恢复**：按 `comet/reference/dirty-worktree.md` 协议处理未提交改动。该协议定义了检查步骤、归因分类和禁令。build 阶段的特殊处理：
+  1. 归因后，若 diff 暗示计划或 spec 已变化，按 Step 4「Spec 增量更新」分级处理
+- **长任务拆分**：单任务超过 200 行代码变更时，考虑拆分为多个子任务分别提交
+
+## 退出条件
+
+- tasks.md 全部勾选
+- 代码已提交
+- 已显式运行项目对应的构建/测试命令并通过（不要只依赖 guard 自动猜测）
+- `isolation` 已写为 `branch` 或 `worktree`
+- `build_mode` 已写为 `subagent-driven-development`、`executing-plans` 或带显式 override 的 `direct`
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> build --apply`，全部 PASS 后自动流转到 `phase: verify`
+
+Guard 会优先读取项目配置中的命令：
+
+```yaml
+build_command: <build command>
+verify_command: <verify command>
+```
+
+配置位置可为 change 的 `.comet.yaml`，也可为仓库根目录的 `.comet.yaml` / `comet.yaml` / `.comet.yml` / `comet.yml`。
+未配置时才回退到 `npm run build`、Maven 或 Cargo 的默认探测。构建失败时 guard 会打印失败命令输出，作为排查证据。
+
+退出前运行 guard 自动流转：
+
+```bash
+bash "$COMET_GUARD" <change-name> build --apply
+```
+
+状态文件自动更新为 `phase: verify`、`verify_result: pending`。
+
+## 自动流转
+
+退出条件满足后（包括用户选择工作方式），自动流转到下一阶段：
+
+> **REQUIRED NEXT SKILL:** 调用 `comet-verify` skill 进入验证与收尾阶段。

+# Comet 阶段 2：深度设计（Design）
+
+## 前置条件
+
+- 活跃 change 已存在（proposal.md、design.md、tasks.md）
+- 无 Design Doc（`docs/superpowers/specs/` 下无对应文件）
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+bash "$COMET_STATE" check <name> design
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：所有 design 阶段操作可以安全重试。如果 `handoff_context` 和 `handoff_hash` 已存在，先确认它们与当前产物一致再决定是否重新生成。
+
+### 1a. 生成 OpenSpec → Superpowers 交接包
+
+**必须由脚本生成，不允许 agent 临场手写 summary 代替。**
+
+```bash
+bash "$COMET_HANDOFF" <change-name> design --write
+```
+
+脚本会生成并记录：
+
+```
+openspec/changes/<name>/.comet/handoff/design-context.json
+openspec/changes/<name>/.comet/handoff/design-context.md
+```
+
+并在 `.comet.yaml` 写入：
+
+```yaml
+handoff_context: openspec/changes/<name>/.comet/handoff/design-context.json
+handoff_hash: <sha256>
+```
+
+默认交接包是 **compact 可追溯摘录**，不是 agent summary：
+- `design-context.json`：机器索引，包含 change、phase、canonical spec、source paths、hash
+- `design-context.md`：供 Superpowers 阅读的上下文，包含脚本标记、source path、line range、sha256、确定性摘录
+- 超出摘录预算时标记 `[TRUNCATED]`，并保留 Full source 路径
+
+如确实需要全文上下文，可显式运行：
+
+```bash
+bash "$COMET_HANDOFF" <change-name> design --write --full
+```
+
+交接包来源来自 OpenSpec open 阶段产物：
+- `proposal.md`：目标、动机、范围、非目标
+- `design.md`：高层架构决策、方案约束
+- `tasks.md`：初始任务边界
+- `specs/*/spec.md`：delta 能力规格
+
+### 1b. 执行 Brainstorming（带上下文）
+
+**立即执行：** 使用 Skill 工具加载 `superpowers:brainstorming` 技能，ARGUMENTS 包含：
+
+```
+Change: <change-name>
+OpenSpec Context Pack: openspec/changes/<name>/.comet/handoff/design-context.md
+Machine handoff: openspec/changes/<name>/.comet/handoff/design-context.json
+
+OpenSpec 产物是上游事实源，不要重新定义需求，不要重写 proposal/spec。
+你的任务是基于交接包做深度技术设计：实现方案、技术风险、测试策略、边界条件。
+如发现 OpenSpec delta spec 缺少验收场景，只能提出 Spec Patch，并回写 OpenSpec delta spec；不要在 Design Doc 中创建第二份需求 spec。
+
+Design Doc frontmatter 必须最小化，只包含：
+---
+comet_change: <change-name>
+role: technical-design
+canonical_spec: openspec
+---
+
+跳过重复上下文探索，直接进入设计提问。
+```
+
+禁止跳过此步骤，禁止在未加载该技能的情况下继续。
+
+如 `superpowers:brainstorming` 不可用，停止流程并提示安装或启用 Superpowers 技能，不要用普通对话替代该步骤。
+
+技能加载后，按其指引产出设计方案（以对话形式呈现）：
+- 技术方案：架构、数据流、关键技术选型与风险
+- 测试策略
+- 如需补充验收场景，标明将回写的 delta spec 变更
+
+brainstorming 阶段不写入 Design Doc 文件，仅产出设计方案供 Step 1c 用户确认。确认后才创建 `docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md` 并回写 delta spec。
+
+### 1c. 用户确认设计方案（阻塞点）
+
+brainstorming 产出设计方案后，**必须使用 AskUserQuestion 工具暂停并等待用户明确确认设计方案**。不得在用户确认前创建最终 Design Doc、写入 `design_doc`、运行 design guard，或进入 `/comet-build`。也不得仅输出文字提示后继续执行。
+
+暂停时只展示必要摘要：
+- 采用的技术方案
+- 关键取舍与风险
+- 测试策略
+- 如有 Spec Patch，列出将回写的 delta spec 变更
+
+用户明确确认后，才继续 Step 2。若用户要求调整，继续 brainstorming 迭代，直到用户确认。
+
+### 2. 更新 Comet 状态
+
+先记录 design_doc 路径。如果 Step 1c 回写了 delta spec（新增或修改了 `specs/*/spec.md`），必须重新生成 handoff 以更新 hash：
+
+```bash
+# 记录 design_doc 路径
+bash "$COMET_STATE" set <name> design_doc docs/superpowers/specs/YYYY-MM-DD-topic-design.md
+
+# 如有 delta spec 变更，重新生成 handoff（更新 hash）
+bash "$COMET_HANDOFF" <change-name> design --write
+
+# 自动流转到下一阶段
+bash "$COMET_GUARD" <change-name> design --apply
+```
+
+如果没有 delta spec 变更，跳过 handoff 重新生成步骤。状态文件自动更新，无需手动编辑其他字段。
+
+## 退出条件
+
+- Design Doc 已创建并保存
+- Design Doc frontmatter 包含 `comet_change`、`role: technical-design`、`canonical_spec: openspec`
+- `handoff_context` 和 `handoff_hash` 已写入 `.comet.yaml`（由 guard 强制校验）
+- `handoff_hash` 与当前 OpenSpec open 阶段产物一致（由 guard 强制校验）
+- `design-context.md` 必须是脚本生成，且包含 source path、mode、sha256 等可追溯标记（由 guard 强制校验）
+- 如有新能力或补充验收场景，OpenSpec delta spec 已创建/更新
+- `design_doc` 已写入 `.comet.yaml`
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> design --apply`，全部 PASS 后自动流转到 `phase: build`
+
+退出前必须使用 `--apply`：
+
+```bash
+bash "$COMET_GUARD" <change-name> design --apply
+```
+
+## 上下文压缩恢复
+
+design 阶段在 brainstorming 过程中可能触发上下文压缩。恢复时先运行：
+
+```bash
+bash "$COMET_STATE" check <change-name> design --recover
+```
+
+脚本输出结构化恢复上下文（阶段、已完成字段、待完成字段、恢复动作）。按 Recovery action 判断下一步。
+
+## 自动流转
+
+退出条件满足后（包括用户确认设计方案），自动流转到下一阶段：
+
+> **REQUIRED NEXT SKILL:** 调用 `comet-build` skill 进入计划与构建阶段。

+
+# Comet 预设路径：Hotfix
+
+快速 bug fix 工作流：open → build → verify → archive。跳过 brainstorming 和完整 plan，适用于行为修复、不涉及新 capability 设计的场景。
+
+**适用条件**（必须全部满足）：
+1. 修复已有功能的 bug，不新增 capability
+2. 不涉及接口变更或架构调整
+3. 改动范围可预估（通常 ≤ 2 个文件）
+
+**不适用**：如修复过程发现需要架构调整，应升级为完整 `/comet` 流程。
+
+---
+
+## 流程（preset workflow，5 阶段）
+
+执行链路：open → build → verify → archive。Hotfix 为每个阶段提供默认决策：精简开启、直接构建、按规模验证、验证通过后归档。
+
+开始前先定位 Comet 脚本：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+```
+
+### 1. 快速开启（preset open）
+
+复用 Comet open 能力创建 change，但使用 hotfix 默认值：不执行 `openspec-explore` 长探索，直接进入精简 change 创建。
+
+**立即执行：** 使用 Skill 工具加载 `openspec-new-change` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引创建精简版产物：
+  - `proposal.md` — 问题描述 + 根因分析 + 修复目标（无需方案对比）
+  - `design.md` — 修复方案（1 个即可，无需多方案对比）
+  - `tasks.md` — 修复任务清单
+- **无需 delta spec**（除非修复改变了已有 spec 的验收场景）
+
+初始化 Comet 状态文件：
+
+```bash
+bash "$COMET_STATE" init <name> hotfix
+```
+
+初始化后验证状态：
+
+```bash
+bash "$COMET_STATE" check <name> open
+```
+
+阶段守卫完成 open → build 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> open --apply
+```
+
+### 2. 直接构建（preset build）
+
+使用 hotfix 默认值：`build_mode: direct`。跳过 `superpowers:brainstorming` 和 `superpowers:writing-plans`（除非任务 > 3 个；若超过 3 个任务，转入 `/comet-build` 的计划与执行方式选择）。
+
+继续或开始修改前，按 `comet/reference/dirty-worktree.md` 协议处理未提交改动。若归因后发现修复范围超出 hotfix，按本文件“升级条件”处理。
+
+**立即执行：** 按 tasks.md 逐个执行任务：
+
+1. 读取 `openspec/changes/<name>/tasks.md`，获取未完成任务列表
+2. 对每个未完成任务：
+   - 根据任务描述修改代码
+   - 运行项目格式化命令（如 `mvn spotless:apply`、`npm run format` 等）
+   - 运行相关测试确认通过
+   - 将 tasks.md 中对应 `- [ ]` 勾选为 `- [x]`
+   - 提交代码，commit message 格式：`fix: <简述修复>`
+3. 全部任务完成后，显式运行项目相关测试和构建命令
+
+**如修复影响已有 spec 验收场景**：
+- 在 `openspec/changes/<name>/specs/<capability>/spec.md` 创建 delta spec
+- 仅包含 `## MODIFIED Requirements` 部分
+
+### 3. 根因消除检查
+
+**在运行 build guard 之前执行**，确保修复确实消除了问题根因：
+
+1. 读取 proposal.md 中的 bug 描述和根因
+2. 搜索验证问题代码不再存在
+3. 如根因未消除，回到 Step 2 继续修复（此时仍在 build 阶段，无需状态回退）
+
+**升级条件**：
+- 根因消除检查发现深层架构问题 → 停止 hotfix，按升级条件阻塞确认处理
+- 修复需要额外接口变更 → 停止 hotfix，按升级条件阻塞确认处理
+
+根因确认消除后，运行阶段守卫完成 build → verify 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> build --apply
+```
+
+状态文件自动更新为 `phase: verify`、`verify_result: pending`，然后进入验证。
+
+### 4. 验证（preset verify）
+
+复用 `/comet-verify`，由 comet-verify 的规模评估决定轻量或完整验证。
+
+**立即执行：** 使用 Skill 工具加载 `comet-verify` 技能。禁止跳过此步骤。
+
+无 delta spec 的小范围 hotfix 通常满足轻量验证条件（≤ 3 tasks、≤ 2 files），comet-verify 的规模评估会选择轻量验证路径（5 项快速检查）。若 hotfix 创建了 delta spec，则根据 comet-verify 的规模评估规则进入完整验证路径。
+
+验证通过后，按 `/comet-verify` 的规则将 `.comet.yaml` 的 `verify_result` 记录为 `pass`，归档前不得跳过该状态。
+
+### 5. 归档（preset archive）
+
+复用 `/comet-archive`。归档前必须满足 `.comet.yaml` 中 `verify_result: pass`。
+
+**立即执行：** 使用 Skill 工具加载 `comet-archive` 技能进行归档。禁止跳过此步骤。
+如有 delta spec，按 comet-archive 规则同步到 main spec，并处理关联 Design Doc 与 Plan 的归档标注。
+
+---
+
+## 连续执行模式
+
+<IMPORTANT>
+Hotfix 流程为 **一次性连续执行**。调用 `/comet-hotfix` 后，agent 在 hotfix 自有步骤间自动推进，不主动停顿。但以下情况必须暂停等待用户确认：
+
+1. 遇到升级条件（见"升级条件"章节），**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整流程
+2. 任务超过 3 个转入 `/comet-build` 时的工作区隔离和执行方式选择
+3. 验证阶段（comet-verify）的验证失败决策和分支处理决策
+
+执行顺序：快速开启 → 直接构建 → 根因消除检查 → 验证 → 归档 → 完成
+
+每个阶段完成后立即进入下一阶段。阶段内部仍必须按上文要求调用对应 Comet/OpenSpec/Superpowers skill，被调用的 skill 如有自己的用户决策点，按该 skill 规则执行。
+</IMPORTANT>
+
+---
+
+## 升级条件
+
+满足以下**任一**条件时，停止 hotfix 流程，升级为完整 `/comet`：
+
+| 条件 | 说明 |
+|------|------|
+| 改动涉及 **3+ 文件** | 超出单点修复范围 |
+| 架构变更 | 新模块、新接口、新依赖 |
+| 数据库 schema 变更 | 结构性调整 |
+| 引入新的 public API | 修复产生了新的对外接口 |
+| 修复范围超出单一函数/模块 | 需要多处协调修改 |
+
+满足升级条件时**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整 `/comet` 流程。不得直接进入 `/comet-design`，不得自动补充 Design Doc。不得仅输出文字提示后继续执行。
+
+用户确认升级后，**必须先更新 workflow 字段**再进入完整流程：
+
+```bash
+bash "$COMET_STATE" set <name> workflow full
+```
+
+然后在当前 change 基础上补充 Design Doc：**立即使用 Skill 工具加载 `comet-design` skill**，后续正常走完整流程。若用户不确认升级，停止 hotfix 并报告当前变更已超出 hotfix 适用范围。
+
+---
+
+## 退出条件
+
+- Bug 已修复，测试通过
+- change 已归档
+- 如有 spec 变更，已同步到 main spec
+- **阶段守卫**：build → verify 前运行 `bash "$COMET_GUARD" <change-name> build --apply`，verify → archive 前按 `/comet-verify` 规则运行 `bash "$COMET_GUARD" <change-name> verify --apply`

+
+# Comet 阶段 1：开启（Open）
+
+## 前置条件
+
+- 无活跃 change，或用户希望创建新 change
+
+## 步骤
+
+### 1. 探索想法
+
+**立即执行：** 使用 Skill 工具加载 `openspec-explore` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引自由探索问题空间。
+
+### 2. 创建 Change 结构 + 初始化状态
+
+**立即执行：** 使用 Skill 工具加载 `openspec-new-change` 技能。若用户意图未明确、需要先形成建议，改为加载 `openspec-propose`。禁止跳过此步骤。
+
+**命名与范围守卫**：change name 必须使用用户指定或通过 AskUserQuestion 确认的名称，不得自动生成或推断。变更范围必须与用户描述一致，不得自行扩大或缩小。
+
+确认以下产物已创建：
+
+```
+openspec/changes/<name>/
+├── .openspec.yaml
+├── .comet.yaml
+├── proposal.md       # Why + What：问题、目标、范围
+├── design.md         # How（高层）：架构决策、方案选型
+└── tasks.md          # 任务清单（勾选框）
+```
+
+创建 `.comet.yaml` 状态文件：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"

+```
+
+### 3. 入口状态验证
+
+验证状态机已正确初始化：
+
+```bash
+bash "$COMET_STATE" check <name> open
+```
+
+验证通过后继续 Step 4。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：open 阶段所有操作可安全重复执行。如 `.comet.yaml` 已处于 `phase: open` 且三个产物文件均已存在，跳过已完成步骤，从第一个缺失步骤继续。
+
+### 4. 内容完整性检查
+
+确认三个文档内容完整：
+- **proposal.md**：问题背景、目标、范围、非目标
+- **design.md**：高层架构决策、方案选型、数据流
+- **tasks.md**：任务列表，每个任务有明确描述
+
+**文件存在性验证**：逐个确认三个文件路径存在且非空。任一文件缺失或为空时，不得进入 Step 5 或执行阶段守卫，必须回到创建步骤补充。
+
+### 5. 用户审视确认（阻塞点）
+
+三个文档创建完成且内容完整性检查通过后，**必须使用 AskUserQuestion 工具暂停并等待用户确认**。不得在用户确认前执行阶段守卫或自动流转。
+
+AskUserQuestion 必须以单选题形式呈现，包含以下摘要和选项：
+
+**摘要内容**：
+- **proposal.md**：问题背景、目标、范围
+- **design.md**：高层架构决策、方案选型
+- **tasks.md**：任务数量和关键任务描述
+
+**选项**：
+- 「确认，继续下一阶段」— 产物符合预期，执行阶段守卫流转
+- 「需要调整」— 附带调整说明，修改后重新请求确认
+
+用户选择「确认」后继续执行退出条件。用户选择「需要调整」时，按其说明修改对应文件，然后重新使用 AskUserQuestion 请求确认。
+
+## 退出条件
+
+- proposal.md、design.md、tasks.md 均已创建且内容完整
+- **用户已确认** proposal、design、tasks 内容符合预期
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> open --apply`，全部 PASS 后自动流转到下一阶段
+
+退出前必须使用 `--apply`，否则 `.comet.yaml` 仍停留在 `phase: open`，下一阶段入口检查会失败。

+适用于非 bug 的小范围变更，例如文案调整、配置调整、文档或 prompt 的局部优化。
+
+**适用条件**（必须全部满足）：
+1. 不新增 capability
+2. 不改变架构
+3. 不涉及接口变化
+4. 通常不超过 3 个 tasks、4 个文件
+
+**不适用**：如变更过程中发现需要 capability、架构或接口调整，应升级为完整 `/comet` 流程。
+
+---
+
+## 流程（preset workflow，4 阶段）
+
+执行链路：open → lightweight build → light verify → archive。Tweak 为每个阶段提供默认决策：精简开启、轻量构建、轻量验证、验证通过后归档。
+
+开始前先定位 Comet 脚本：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+```
+
+### 1. 快速开启（preset open）
+
+复用 Comet open 能力创建 change，但使用 tweak 默认值：不执行 `openspec-explore` 长探索，直接进入精简 change 创建。
+
+**立即执行：** 使用 Skill 工具加载 `openspec-new-change` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引创建精简版产物：
+  - `proposal.md` — 变更动机 + 目标 + 范围
+  - `design.md` — 简短实现说明（无需方案对比）
+  - `tasks.md` — 不超过 3 个任务
+- **无需 delta spec**（除非变更改变了已有 spec 的验收场景；一旦需要 delta spec，升级为完整 `/comet`）
+
+初始化 Comet 状态文件：
+
+```bash
+bash "$COMET_STATE" init <name> tweak
+```
+
+初始化后验证状态：
+
+```bash
+bash "$COMET_STATE" check <name> open
+```
+
+阶段守卫完成 open → build 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> open --apply
+```
+
+### 2. 轻量构建（preset build）
+
+使用 tweak 默认值：`build_mode: direct`。跳过 `superpowers:brainstorming` 和 `superpowers:writing-plans`。
+
+继续或开始修改前，按 `comet/reference/dirty-worktree.md` 协议处理未提交改动。若归因后发现范围超出 tweak，按本文件“升级条件”处理。
+
+**立即执行：** 按 tasks.md 逐个执行任务：
+
+1. 读取 `openspec/changes/<name>/tasks.md`，获取未完成任务列表
+2. 对每个未完成任务：
+   - 根据任务描述修改目标文件
+   - 运行项目格式化命令（如 `mvn spotless:apply`、`npm run format` 等）
+   - 运行相关测试确认通过
+   - 将 tasks.md 中对应 `- [ ]` 勾选为 `- [x]`
+   - 提交代码，commit message 格式：`tweak: <简述变更>`
+3. 全部任务完成后，显式运行项目相关测试和构建命令
+4. 运行阶段守卫完成 build → verify 过渡：
+
+```bash
+bash "$COMET_GUARD" <change-name> build --apply
+```
+
+状态文件自动更新为 `phase: verify`、`verify_result: pending`，然后进入验证。
+
+### 3. 轻量验证（preset verify）
+
+复用 `/comet-verify`。Tweak 必须保持轻量验证条件：≤ 3 tasks、≤ 4 files、无 delta spec、无新 capability。
+
+**立即执行：** 使用 Skill 工具加载 `comet-verify` 技能。禁止跳过此步骤。
+
+如规模评估进入完整验证路径，停止 tweak，按升级条件阻塞确认处理。
+
+验证通过后，按 `/comet-verify` 的规则将 `.comet.yaml` 的 `verify_result` 记录为 `pass`，归档前不得跳过该状态。
+
+### 4. 归档（preset archive）
+
+复用 `/comet-archive`。归档前必须满足 `.comet.yaml` 中 `verify_result: pass`。
+
+**立即执行：** 使用 Skill 工具加载 `comet-archive` 技能进行归档。禁止跳过此步骤。
+
+---
+
+## 连续执行模式
+
+<IMPORTANT>
+Tweak 流程为 **一次性连续执行**。调用 `/comet-tweak` 后，agent 在 tweak 自有步骤间自动推进，不主动停顿。但以下情况必须暂停等待用户确认：
+
+1. 遇到升级条件（见"升级条件"章节），**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整流程
+2. 验证阶段（comet-verify）的验证失败决策和分支处理决策
+
+执行顺序：快速开启 → 轻量构建 → 轻量验证 → 归档 → 完成
+
+每个阶段完成后立即进入下一阶段。阶段内部仍必须按上文要求调用对应 Comet/OpenSpec/Superpowers skill，被调用的 skill 如有自己的用户决策点，按该 skill 规则执行。
+</IMPORTANT>
+
+---
+
+## 升级条件
+
+满足以下**任一**条件时，停止 tweak 流程，升级为完整 `/comet`：
+
+| 条件 | 说明 |
+|------|------|
+| 改动涉及 **5+ 文件** | 超出小改动范围 |
+| 多模块协调修改 | 需要跨组件协调 |
+| 需要新增测试用例 **5+** | 变更复杂度上升 |
+| 配置项新增或删除 | 非值修改的配置变更 |
+| 需要新增 capability | 超出局部优化 |
+| 需要 delta spec | 影响了已有规格 |
+
+满足升级条件时**必须使用 AskUserQuestion 工具暂停并等待用户明确确认**升级为完整 `/comet` 流程。不得直接进入 `/comet-design`，不得自动补充 Design Doc。不得仅输出文字提示后继续执行。
+
+用户确认升级后，**必须先更新 workflow 字段**再进入完整流程：
+
+```bash
+bash "$COMET_STATE" set <name> workflow full
+```
+
+然后在当前 change 基础上补充 Design Doc：**立即使用 Skill 工具加载 `comet-design` skill**，后续正常走完整流程。若用户不确认升级，停止 tweak 并报告当前变更已超出 tweak 适用范围。
+
+---
+
+## 退出条件
+
+- 小改动已完成，测试通过
+- change 已归档
+- 未新增 capability、架构调整或接口变化
+- **阶段守卫**：build → verify 前运行 `bash "$COMET_GUARD" <change-name> build --apply`，verify → archive 前按 `/comet-verify` 规则运行 `bash "$COMET_GUARD" <change-name> verify --apply`

+# Comet 阶段 4：验证与收尾（Verify）
+
+## 前置条件
+
+- 代码已提交（阶段 3 完成）
+- tasks.md 全部任务已完成
+
+## 步骤
+
+### 0. 入口状态验证（Entry Check）
+
+执行入口验证：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+bash "$COMET_STATE" check <change-name> verify
+```
+
+验证通过后继续 Step 1。验证失败时脚本会输出具体失败原因。
+
+**幂等性**：verify 阶段所有检查可安全重复执行。如 `verify_result` 已为 `pass` 且 `branch_status` 已为 `handled`，说明验证已完成，直接执行 guard 流转。如 `verify_result` 为 `pending`，从头开始验证。
+
+### 1. 改动规模评估
+
+执行规模评估：
+
+```bash
+bash "$COMET_STATE" scale <change-name>
+```
+
+脚本自动统计任务数、增量规格数、变更文件数，判断使用 light 或 full 验证模式，并设置 verify_mode 字段。
+
+验证开始前，按 `comet/reference/dirty-worktree.md` 协议检查并处理未提交改动。verify 阶段的特殊处理：
+
+1. 若 dirty diff 属于当前 change 且涉及实现、测试、tasks、delta spec 或 design doc 变更，不在 verify 阶段直接修复或提交；报告失败项并进入 Step 1b 的验证失败决策阻塞点
+2. 若 dirty diff 只是 verify 本阶段产物（例如验证报告草稿、分支处理记录），可继续在 verify 阶段完成并记录状态
+3. 若 dirty diff 已实现但 tasks.md 未勾选，视为 build 状态滞后；报告失败项并进入 Step 1b，由用户决定回退修复或接受偏差
+
+用户选择修复后，才允许回退到 build 阶段：
+
+```bash
+# 仅在用户确认修复后执行
+bash "$COMET_STATE" transition <change-name> verify-fail
+```
+
+注意：如果 build 阶段每个任务都已提交，脚本基于工作区 diff 的文件数可能低估改动规模。此时必须读取 plan 文件头的 `base-ref` 并用提交区间复核：
+
+```bash
+PLAN=$(bash "$COMET_STATE" get <change-name> plan)
+BASE_REF=$(grep '^base-ref:' "$PLAN" 2>/dev/null | head -1 | sed 's/^base-ref: *//')
+git diff --stat "$BASE_REF"...HEAD
+```
+
+若提交区间显示改动超过轻量阈值（> 4 个文件、跨模块协调、或 delta spec 超过 1 个 capability），手动设置为完整验证：
+
+```bash
+bash "$COMET_STATE" set <change-name> verify_mode full
+```
+
+### 1b. 验证失败决策（阻塞点）
+
+验证不通过时**必须使用 AskUserQuestion 工具暂停并等待用户决定修复或接受偏差**。不得自动运行 `bash "$COMET_STATE" transition <change-name> verify-fail`，也不得自动调用 `/comet-build`。禁止仅输出文字提示后继续执行。
+
+暂停时必须列出：
+- 失败项
+- 是否属于 CRITICAL（构建失败、测试失败、安全问题、核心验收场景失败）
+- 推荐处理方式
+
+**不确定性原则**：无法确定严重程度时，降级处理（SUGGESTION > WARNING > CRITICAL）。仅对构建失败、测试失败、安全问题使用 CRITICAL；模糊或不确定的问题标为 WARNING 或 SUGGESTION。
+
+用户选择后按以下方式继续：
+- **全部修复**：运行 `bash "$COMET_STATE" transition <change-name> verify-fail`，然后调用 `/comet-build` 修复
+- **逐项处理**：CRITICAL 失败项必须修复；非 CRITICAL 失败项可选择接受偏差，但必须在验证报告中记录接受原因和影响范围。若存在任何 CRITICAL 失败项，不允许跳过修复直接全部接受
+
+### 2a. 轻量验证（小改动）
+
+当规模评估结果为"小"时，跳过 `openspec-verify-change`，直接执行以下检查：
+
+1. tasks.md 全部任务已完成 `[x]`
+2. 改动文件与 tasks.md 描述一致（`git diff --stat` / `git diff --cached --stat` / `git diff --stat <base-ref>...HEAD` 对照 tasks 内容）
+3. 编译通过（执行项目对应的构建命令，如 `npm run build`、`mvn compile`、`cargo build` 等）
+4. 相关测试通过
+5. 无明显安全问题（无硬编码密钥、无新增 unsafe 操作）
+
+**通过标准**：5 项全部 OK，无 CRITICAL 问题。
+
+**不通过时**：报告失败项，进入 Step 1b 的验证失败决策阻塞点。用户选择修复后，才执行以下命令记录失败并回退到 build 阶段，然后调用 `/comet-build` 修复：
+
+```bash
+# 仅在用户确认修复后执行
+bash "$COMET_STATE" transition <change-name> verify-fail
+```
+
+**报告格式**：简表列出 5 项检查结果 + PASS/FAIL。
+
+**跳过项**（不在轻量验证中检查）：
+- spec scenario 覆盖率
+- design doc 一致性深度比对
+- code pattern consistency 建议
+- delta spec 与 design doc 漂移检测
+
+### 2b. 完整验证（大改动）
+
+当规模评估结果为"大"时：
+
+**立即执行：** 使用 Skill 工具加载 `openspec-verify-change` 技能。禁止跳过此步骤。
+
+技能加载后，按其指引验证。检查项：
+1. tasks.md 全部任务已完成（`[x]`）
+2. 实现符合 `openspec/changes/<name>/design.md` 高层设计决策
+3. 实现符合 Design Doc（`docs/superpowers/specs/` 下的技术设计文档）
+4. 能力规格场景全部通过
+5. proposal.md 目标已满足
+6. delta spec 与 design doc 无矛盾（若 Build 阶段有增量修改 spec，检查 design doc 是否有对应记录）
+7. `docs/superpowers/specs/` 关联的设计文档可定位（文件存在且与当前 change 相关）
+
+验证不通过时：报告缺失项，进入 Step 1b 的验证失败决策阻塞点。用户选择修复后，才执行以下命令记录失败并回退到 build 阶段，然后调用 `/comet-build` 补充：
+
+```bash
+# 仅在用户确认修复后执行
+bash "$COMET_STATE" transition <change-name> verify-fail
+```
+
+**Spec 漂移处理**（用户决策点）：
+- 若检查项 6 发现矛盾（delta spec 有内容但 design doc 未体现），**必须使用 AskUserQuestion 工具以单选题形式暂停并等待用户选择处理方式**，不得自动选择。选项：
+  - 选项 A：在 design doc 追加 "Implementation Divergence" 节记录偏差原因。选项 A 属于 verify 阶段允许产物；写入后不得因该 design doc 变更再次触发 Step 1b dirty-worktree 决策
+  - 选项 B：用户选择 B 后，运行 `bash "$COMET_STATE" transition <change-name> verify-fail`，然后调用 `/comet-build`；由 `/comet-build` 的 Spec 增量更新规则加载 `superpowers:brainstorming` 更新 Design Doc + delta spec
+  - 选项 C：确认偏差可接受，继续验证（归档时 design doc 将标记为 `superseded-by-main-spec`）
+
+### 3. 收尾（Superpowers）
+
+**立即执行：** 使用 Skill 工具加载 `superpowers:finishing-a-development-branch` 技能。禁止跳过此步骤。
+
+如 `superpowers:finishing-a-development-branch` 不可用，停止流程并提示安装或启用 Superpowers 技能，不要用普通对话替代该步骤。
+
+技能加载后，按其指引收尾。分支处理选项：
+1. 本地合并到主分支
+2. 推送并创建 PR
+3. 保持分支（稍后处理）
+4. 丢弃工作
+
+这是用户决策点。**必须使用 AskUserQuestion 工具暂停并等待用户选择分支处理方式**，不得根据推荐、默认值或当前分支状态自行选择。禁止仅输出文字提示后继续执行。只有在用户完成选择且对应操作完成后，才允许写入 `branch_status: handled`。
+
+**确认项**：
+- 全部测试通过
+- 无硬编码密钥或安全问题
+
+### 4. 记录验证证据
+
+验证报告必须落盘，并在 `.comet.yaml` 中记录；分支处理完成后也必须写入状态字段。不要手动设置 `verify_result: pass`，通过 guard 自动流转。
+
+```bash
+mkdir -p docs/superpowers/reports
+# 将本次验证结论写入报告文件，例如：
+# docs/superpowers/reports/YYYY-MM-DD-<change-name>-verify.md
+
+bash "$COMET_STATE" set <change-name> verification_report docs/superpowers/reports/YYYY-MM-DD-<change-name>-verify.md
+bash "$COMET_STATE" set <change-name> branch_status handled
+```
+
+## 退出条件
+
+- 验证报告通过
+- 分支已处理
+- `.comet.yaml` 中 `verification_report` 指向已存在的验证报告文件
+- `.comet.yaml` 中 `branch_status: handled`
+- **阶段守卫**：运行 `bash "$COMET_GUARD" <change-name> verify --apply`，全部 PASS 后通过 `comet-state transition verify-pass` 自动流转到 `phase: archive`
+
+验证和分支处理均完成后，运行 guard 自动流转：
+
+```bash
+bash "$COMET_GUARD" <change-name> verify --apply
+```
+
+状态文件自动更新为 `phase: archive`、`verify_result: pass`、`verified_at: YYYY-MM-DD`。
+
+## 上下文压缩恢复
+
+Verify 阶段可能触发上下文压缩。恢复时先运行：
+
+```bash
+bash "$COMET_STATE" check <change-name> verify --recover
+```
+
+脚本输出结构化恢复上下文（phase、验证状态、分支状态、恢复动作），根据输出的 Recovery action 决定下一步。
+
+## 自动流转
+
+退出条件满足后（包括用户选择分支处理方式），自动流转到下一阶段：
+
+> **REQUIRED NEXT SKILL:** 调用 `comet-archive` skill 进入归档阶段。

+
+# Comet — OpenSpec + Superpowers 双星开发流程
+
+OpenSpec 与 Superpowers 如双星系统围绕同一目标运转。
+
+```
+OpenSpec 负责 WHAT  — 大纲、提案、spec 生命周期、归档
+Superpowers 负责 HOW — 技术设计、计划、执行、收尾
+```
+
+**核心原则：brainstorming 必不可跳过。每次变更都必须经过深度设计（hotfix 和 tweak preset 除外）。**
+
+---
+
+## 决策核心（Decision Core）
+
+agent 做决策只需读本节，参考附录按需查阅。
+
+### 阶段自动检测
+
+**Step 0: 活跃 Change 发现与意图判定**
+
+1. 先做 Preset 检测；命中 hotfix/tweak 时直接调用对应 preset skill，不进入普通 open 分支
+2. 未命中 preset 时，运行 `openspec list --json` 获取所有活跃 change
+
+**Preset 检测优先级最高**：
+- 用户明确描述为 bug fix / 热修复 + 满足 hotfix 条件 → 直接 `/comet-hotfix`
+- 用户明确描述为文案/配置/文档/prompt 小调整 + 满足 tweak 条件 → 直接 `/comet-tweak`
+- 未命中 preset → 按下表处理
+
+| 活跃 change | 用户输入 | 行为 |
+|-------------|---------|------|
+| 无 | 非 preset 输入 | → 调用 `/comet-open` |
+| 恰好 1 个 | `/comet <描述>` | → **询问**：继续该变更 or 创建新变更 |
+| 多个 | `/comet <描述>` | → **询问**：继续现有变更 or 创建新变更；若选继续 → 列出清单让用户选择 |
+| 恰好 1 个 | `/comet`（无描述） | → 自动选中，进入 Step 1 |
+| 多个 | `/comet`（无描述） | → 列出清单让用户选择 |
+
+<IMPORTANT>
+当用户选择「创建新变更」时，**必须调用 `/comet-open`**（禁止直接调用 `/opsx:new`）。
+`/comet-open` 负责完整双初始化：OpenSpec artifacts（由内部 `/opsx:new` 创建）+ `.comet.yaml` 状态文件。
+直接调用 `/opsx:new` 会缺失 `.comet.yaml`，导致后续阶段判定失败。
+</IMPORTANT>
+
+**Step 1: 读取 `.comet.yaml` 状态元数据**
+
+优先读取 `openspec/changes/<name>/.comet.yaml`。不存在时回退到 `openspec status --change "<name>" --json`、`tasks.md` 和 `docs/superpowers/` 文件检查。
+
+**断点恢复规则**：
+- 每次恢复上下文时，先重新执行 Step 0 和 Step 1，不依赖对话历史判断阶段
+- 只要存在 active change 且工作区有未提交改动，必须按 `comet/reference/dirty-worktree.md` 协议处理。该协议定义了检查步骤、归因分类和禁令，本文件不重复
+- 若 `phase: build`，先检查 `build_mode` 和 `isolation` 是否已设置；若有未设置的字段，回到 `/comet-build` 对应步骤补充后再执行；若均已设置，读取 tasks.md 的下一个未勾选任务继续
+- 若 `phase: verify` 且 `verify_result: fail`，进入验证失败决策阻塞点：暂停并询问用户修复或接受偏差；用户选择修复后才运行 `bash "$COMET_STATE" transition <name> verify-fail` 并调用 `/comet-build`
+- 若 `phase: open` 但 proposal/design/tasks 已完整，先运行 `bash "$COMET_GUARD" <change-name> open --apply` 修正状态，再继续判定
+- 若 `phase: archive`，只允许调用 `/comet-archive`；归档成功后 change 会移动到 archive 目录，不再对原活跃目录运行 guard
+
+**Step 2: 阶段判定**（按顺序，命中即停）
+
+1. `archived: true` 或 change 已移入 archive → 流程已完成
+2. `verify_result: pass` 且 `archived` 不是 `true` → `/comet-archive`
+3. `verify_result: fail` → 进入验证失败决策阻塞点（暂停询问修复或接受偏差；用户选择修复后才 `verify-fail` 并 `/comet-build`）
+4. `phase: verify` 或 tasks.md 全部勾选 → `/comet-verify`
+5. `phase: build` 或已有 Design Doc 但计划/执行未完成 → 优先按 workflow 路由：`hotfix` → `/comet-hotfix`，`tweak` → `/comet-tweak`，`full` → `/comet-build`
+6. `phase: design` 或有 change 但无 Design Doc → `/comet-design`
+7. `phase: open` 或有活跃 change 但 `.comet.yaml` 缺失 → `/comet-open`
+8. 无活跃 change → `/comet-open`
+
+如果元数据与文件状态冲突，以文件状态为准，修正 `.comet.yaml` 后继续。
+
+### 预设升级条件
+
+**hotfix → full**（满足任一即升级）：
+- 改动涉及 **3+ 文件**
+- 涉及架构变更（新模块、新接口、新依赖）
+- 涉及数据库 schema 变更
+- 修复引入新的 public API
+- 修复范围超出单一函数/模块
+
+**tweak → full**（满足任一即升级）：
+- 改动涉及 **5+ 文件**
+- 涉及多个模块的协调修改
+- 需要新增测试用例 **5+**
+- 涉及配置项的新增或删除（非值修改）
+
+### 错误处理速查
+
+| 场景 | 处理方式 |
+|------|---------|
+| `openspec list --json` 失败 | 检查 openspec 是否已安装，提示 `openspec init` |
+| 子 skill 不可用 | 停止流程，提示安装或启用对应 skill |
+| `.comet.yaml` 格式异常或缺失 | 以文件状态为准，用 `bash $COMET_STATE set` 修正后继续 |
+| 构建/测试失败 | 返回 build 阶段修复，不进入 verify |
+| change 目录结构不完整 | 按 `comet-open` 产物要求补齐 |
+
+### 阶段衔接
+
+<IMPORTANT>
+单次 `/comet` 调用从检测到的阶段开始，退出条件满足后进入下一阶段。
+
+流转链：open → design → build → verify → archive
+
+**连续执行要求**：从检测到的阶段开始，agent 自动推进后续阶段。但**自动推进仅适用于没有用户决策的衔接点**。遇到用户决策点时，**必须使用 AskUserQuestion 工具暂停并等待用户明确回复**，不得用推荐规则、默认值或历史偏好代替用户确认，也不得仅输出文字提示后继续执行。
+
+**决策点是阻塞点**：只要到达下列任一节点，当前 `/comet` 调用必须停住，**使用 AskUserQuestion 工具等待用户选择**。用户明确选择后才能写入对应状态字段、执行对应操作，随后再继续自动流转。
+
+需要用户参与的节点（仅在这些节点暂停）：
+1. open 阶段 proposal/design/tasks 审视确认
+2. brainstorming 确认设计方案
+3. build 阶段选择工作方式（隔离方式 + 执行方式，一次交互完成）
+4. verify 不通过时决定修复或接受偏差（含 Spec 漂移处理方式选择）
+5. finishing-branch 选择分支处理方式
+6. 遇到升级条件（hotfix/tweak → 完整流程）
+7. build 阶段范围扩张需重新设计或拆分新 change
+
+agent 不应跳过这些决策点；其他明确无歧义的阶段衔接必须自动继续推进，不得中途退出。到达决策点时，**禁止以文字输出代替工具等待——必须通过 AskUserQuestion 明确获取用户选择后才能继续**。
+
+**红旗清单** — 以下想法出现时立即停止并检查：
+
+| Agent 心理 | 实际风险 |
+|-----------|---------|
+| "用户应该会同意这个方案" | 不能替用户决策，用 AskUserQuestion |
+| "这只是个小改动，不需要确认" | 决策点无大小之分，阻塞点必须等待 |
+| "用户之前选过 A，这次也选 A" | 历史偏好不能替代当前确认 |
+| "我已经解释了方案，用户没反对" | 没反对 ≠ 同意，必须用工具获取明确选择 |
+| "流程走到这里应该没问题了" | 验证不通过 ≠ 通过，检查 verify_result |
+</IMPORTANT>
+
+---
+
+## 子命令速查
+
+| 命令 | 阶段 | 归属 | 产物 |
+|------|------|------|------|
+| `/comet-open` | 1. 开启 | OpenSpec | proposal.md、design.md、tasks.md |
+| `/comet-design` | 2. 深度设计 | Superpowers | Design Doc、delta spec |
+| `/comet-build` | 3. 计划与构建 | Superpowers | 实施计划、代码提交 |
+| `/comet-verify` | 4. 验证与收尾 | Both | 验证报告、分支处理 |
+| `/comet-archive` | 5. 归档 | OpenSpec | delta→main spec 同步、design doc 标注、归档 |
+| `/comet-hotfix` | 预设路径 | Both | 快速修复（跳过 brainstorming） |
+| `/comet-tweak` | 预设路径 | Both | 小改动（跳过 brainstorming 和完整 plan） |

+| `base_ref` | init 时记录的 git commit SHA，用于 scale 评估。无 plan 时作为改动文件数统计基准 |
+| `build_mode` | 已选择的执行方式，可为空 |
+| `isolation` | `branch` 或 `worktree`，工作区隔离方式。full 初始化可为 `null`，但只允许持续到 `/comet-build` Step 3 前；hotfix/tweak 默认 `branch` |
+| `verify_mode` | `light` 或 `full`，可为空 |
+| `verify_result` | `pending`、`pass` 或 `fail` |
+| `verification_report` | 验证报告文件路径，verify 通过前必须指向已存在文件 |
+| `branch_status` | `pending` 或 `handled`，分支处理完成后设为 `handled` |
+| `created_at` | change 创建日期（init 时自动写入），格式 `YYYY-MM-DD` |
+| `verified_at` | 验证通过时间，可为空 |
+| `archived` | change 是否已归档 |
+
+可选字段：
+
+| 字段 | 含义 |
+|------|------|
+| `direct_override` | `true`/`false`。full workflow 如需使用 `build_mode: direct`，必须显式设为 `true` |
+| `build_command` | 项目构建命令。guard 优先运行该命令，失败时打印命令输出 |
+| `verify_command` | 项目验证命令。verify guard 优先运行该命令，未配置时回退到构建命令 |
+
+状态机硬约束：
+- `build → verify` 前，`isolation` 必须是 `branch` 或 `worktree`
+- `build → verify` 前，`build_mode` 必须已选择
+- `build_mode: direct` 默认只允许 `hotfix` / `tweak`；full workflow 需要 `direct_override: true`
+- 这些约束同时存在于 `comet-guard.sh build --apply` 和 `comet-state.sh transition <name> build-complete`
+
+### 脚本定位
+
+Comet 脚本随 skill 包分发在 `comet/scripts/` 下。**不硬编码路径** — 定位一次，缓存到环境变量：
+
+```bash
+COMET_ENV="${COMET_ENV:-$(find . "$HOME"/.*/skills "$HOME/.config" "$HOME/.gemini" -path '*/comet/scripts/comet-env.sh' -type f -print -quit 2>/dev/null)}"
+if [ -z "$COMET_ENV" ]; then
+  echo "ERROR: comet-env.sh not found. Ensure the comet skill is installed." >&2
+  return 1
+fi
+. "$COMET_ENV"
+
+# 脚本定位失败时停止流程
+if [ -z "$COMET_GUARD" ] || [ -z "$COMET_STATE" ] || [ -z "$COMET_HANDOFF" ] || [ -z "$COMET_ARCHIVE" ]; then
+  echo "ERROR: Comet scripts not found. Ensure the comet skill is installed." >&2
+  echo "Expected path pattern: */comet/scripts/comet-*.sh under project or platform skill directories" >&2
+  return 1
+fi
+```
+
+**自动状态更新**：guard 支持 `--apply` 参数，验证通过后自动更新 `.comet.yaml` 状态字段：
+
+```bash
+bash "$COMET_GUARD" <change-name> <phase> --apply
+```
+
+`--apply` 内部委托给 `comet-state transition`。需要直接表达状态事件时使用：
+
+```bash
+bash "$COMET_STATE" transition <change-name> open-complete
+bash "$COMET_STATE" transition <change-name> design-complete
+bash "$COMET_STATE" transition <change-name> build-complete
+bash "$COMET_STATE" transition <change-name> verify-pass
+bash "$COMET_STATE" transition <change-name> verify-fail
+bash "$COMET_STATE" transition <archive-name> archived
+```
+
+**归档脚本**：一键完成归档全部步骤：
+
+```bash
+bash "$COMET_ARCHIVE" <change-name>
+```
+
+加载 comet 后，agent 应执行以上变量赋值一次，后续全程复用 `$COMET_GUARD`、`$COMET_STATE`、`$COMET_HANDOFF`、`$COMET_ARCHIVE`。
+
+### 文件结构

+```
+
+### 最佳实践
+
+1. **brainstorming 不可跳过** — 每次变更必须经过深度设计（hotfix 和 tweak 除外）
+2. **delta spec 是活文档** — 阶段 3 期间可自由修改，归档时同步
+3. **交接包由脚本生成** — OpenSpec → Superpowers 的上下文必须通过 `comet-handoff.sh` 生成 compact 可追溯摘录（必要时 `--full`），并由 guard 校验 source/hash/mode
+4. **保持 tasks.md 同步** — 完成一个勾一个
+5. **频繁提交** — 每个任务一次提交，message 体现设计意图
+6. **先验证再归档** — `/comet-verify` 通过后才执行 `/comet-archive`
+7. **增量更新分级** — 小编辑、中重 brainstorming、大新 change
+8. **Plan 必须关联 change** — 文件头包含 `change:` 和 `design-doc:` 元数据
+9. **归档闭环** — design doc 和 plan 必须标注 `archived-with` 状态
+10. **修改已有功能** — 直接 open 新 change 即可
+11. **Preset 有上限** — hotfix/tweak 满足升级条件时及时切换到完整流程

+# Dirty Worktree 协议
+
+规范路径：`comet/reference/dirty-worktree.md`
+
+本协议由所有涉及代码修改的 comet 子 skill 共享。当 agent 恢复上下文或继续执行时，必须按本协议处理未提交的工作区改动。
+
+## 1. 检查步骤
+
+继续或开始修改前，必须先运行以下命令：
+
+```bash
+git status --short
+git diff --stat
+git diff --cached --stat
+git ls-files --others --exclude-standard
+```
+
+必要时再查看 `git diff` / `git diff --cached` / 新建文件内容。
+
+## 2. 核心规则
+
+- 用户可能不会说明自己改了哪里。只要存在 dirty worktree（包括 Git 状态里显示为 `??` 的新建文件），就先假设改动可能来自用户或混合来源
+- dirty worktree 只代表代码事实，不会自动推进 `.comet.yaml` 的 `phase` 或勾选 `tasks.md`；只有完成归因、验证、同步必要文档，并通过对应阶段 guard 后，才允许推进 Comet 状态
+
+## 3. 归因分类
+
+将 dirty diff 分为三类：
+
+1. **属于当前 change**：文件和内容能对应当前 change 的目标、tasks.md、plan 或 delta spec。将其纳入当前任务继续，不重复改同一处
+2. **不属于当前 change**：文件或内容与当前目标无关。暂停并询问用户：并入当前 change、拆成新 change、保留不处理，或明确授权丢弃
+3. **来源不确定**：无法从 diff 和文档判断归属。暂停并向用户汇报文件列表和判断依据，不继续推进阶段
+
+## 4. 常见处理模式
+
+### 已实现但 tasks.md 未勾选
+
+先验证实现（运行构建和测试），通过后补勾任务。不要因为任务未勾选就重做一遍，也不要因为状态文件滞后而忽略代码事实。若当前子 skill 定义了阶段特例，以子 skill 为准。
+
+### 暗示计划或范围已变化
+
+按当前子 skill 的升级、增量更新或回退规则处理，本协议不重复阶段特例。
+
+### 模糊恢复意图
+
+用户说"继续""接着跑""我改了一点""刚才不满意""重新弄""代码动过""先按现在的来"等模糊恢复意图时，按本协议处理。不要要求用户先回忆具体改了哪里。
+
+### open/design 阶段出现代码改动
+
+若当前仍处于 `open` 或 `design`，但 dirty worktree 已经包含代码改动，先按本协议归因，不要直接推进阶段：
+
+- 属于当前 change 的改动：作为需求或设计输入记录到 proposal/design/spec/design doc/tasks 中；进入 build 前仍需完成对应阶段 guard
+- 不属于当前 change 或来源不确定：暂停询问用户是并入当前 change、拆成新 change、保留不处理，还是明确授权丢弃
+- 禁止在 open/design 阶段直接把代码改动当作已完成实现并推进到 verify
+
+## 5. 禁令
+
+- 禁止在未理解 dirty diff 来源时覆盖、回滚、格式化重写或忽略用户改动
+- 禁止在 dirty diff 未解释清楚时判定验证通过

+name: dispatching-parallel-agents
+description: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
+---
+
+# Dispatching Parallel Agents
+
+## Overview
+
+You delegate tasks to specialized agents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.
+
+When you have multiple unrelated failures (different test files, different subsystems, different bugs), investigating them sequentially wastes time. Each investigation is independent and can happen in parallel.
+
+**Core principle:** Dispatch one agent per independent problem domain. Let them work concurrently.
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Multiple failures?" [shape=diamond];
+    "Are they independent?" [shape=diamond];
+    "Single agent investigates all" [shape=box];
+    "One agent per problem domain" [shape=box];
+    "Can they work in parallel?" [shape=diamond];
+    "Sequential agents" [shape=box];
+    "Parallel dispatch" [shape=box];
+
+    "Multiple failures?" -> "Are they independent?" [label="yes"];
+    "Are they independent?" -> "Single agent investigates all" [label="no - related"];
+    "Are they independent?" -> "Can they work in parallel?" [label="yes"];
+    "Can they work in parallel?" -> "Parallel dispatch" [label="yes"];
+    "Can they work in parallel?" -> "Sequential agents" [label="no - shared state"];
+}
+```
+
+**Use when:**
+- 3+ test files failing with different root causes
+- Multiple subsystems broken independently
+- Each problem can be understood without context from others
+- No shared state between investigations
+
+**Don't use when:**
+- Failures are related (fix one might fix others)
+- Need to understand full system state
+- Agents would interfere with each other
+
+## The Pattern
+
+### 1. Identify Independent Domains
+
+Group failures by what's broken:
+- File A tests: Tool approval flow
+- File B tests: Batch completion behavior
+- File C tests: Abort functionality
+
+Each domain is independent - fixing tool approval doesn't affect abort tests.
+
+### 2. Create Focused Agent Tasks
+
+Each agent gets:
+- **Specific scope:** One test file or subsystem
+- **Clear goal:** Make these tests pass
+- **Constraints:** Don't change other code
+- **Expected output:** Summary of what you found and fixed
+
+### 3. Dispatch in Parallel
+
+```typescript
+// In Claude Code / AI environment
+Task("Fix agent-tool-abort.test.ts failures")
+Task("Fix batch-completion-behavior.test.ts failures")
+Task("Fix tool-approval-race-conditions.test.ts failures")
+// All three run concurrently
+```
+
+### 4. Review and Integrate
+
+When agents return:
+- Read each summary
+- Verify fixes don't conflict
+- Run full test suite
+- Integrate all changes
+
+## Agent Prompt Structure
+
+Good agent prompts are:
+1. **Focused** - One clear problem domain
+2. **Self-contained** - All context needed to understand the problem
+3. **Specific about output** - What should the agent return?
+
+```markdown
+Fix the 3 failing tests in src/agents/agent-tool-abort.test.ts:
+
+1. "should abort tool with partial output capture" - expects 'interrupted at' in message
+2. "should handle mixed completed and aborted tools" - fast tool aborted instead of completed
+3. "should properly track pendingToolCount" - expects 3 results but gets 0
+
+These are timing/race condition issues. Your task:
+
+1. Read the test file and understand what each test verifies
+2. Identify root cause - timing issues or actual bugs?
+3. Fix by:
+   - Replacing arbitrary timeouts with event-based waiting
+   - Fixing bugs in abort implementation if found
+   - Adjusting test expectations if testing changed behavior
+
+Do NOT just increase timeouts - find the real issue.
+
+Return: Summary of what you found and what you fixed.
+```
+
+## Common Mistakes
+
+**❌ Too broad:** "Fix all the tests" - agent gets lost
+**✅ Specific:** "Fix agent-tool-abort.test.ts" - focused scope
+
+**❌ No context:** "Fix the race condition" - agent doesn't know where
+**✅ Context:** Paste the error messages and test names
+
+**❌ No constraints:** Agent might refactor everything
+**✅ Constraints:** "Do NOT change production code" or "Fix tests only"
+
+**❌ Vague output:** "Fix it" - you don't know what changed
+**✅ Specific:** "Return summary of root cause and changes"
+
+## When NOT to Use
+
+**Related failures:** Fixing one might fix others - investigate together first
+**Need full context:** Understanding requires seeing entire system
+**Exploratory debugging:** You don't know what's broken yet
+**Shared state:** Agents would interfere (editing same files, using same resources)
+
+## Real Example from Session
+
+**Scenario:** 6 test failures across 3 files after major refactoring
+
+**Failures:**
+- agent-tool-abort.test.ts: 3 failures (timing issues)
+- batch-completion-behavior.test.ts: 2 failures (tools not executing)
+- tool-approval-race-conditions.test.ts: 1 failure (execution count = 0)
+
+**Decision:** Independent domains - abort logic separate from batch completion separate from race conditions
+
+**Dispatch:**
+```
+Agent 1 → Fix agent-tool-abort.test.ts
+Agent 2 → Fix batch-completion-behavior.test.ts
+Agent 3 → Fix tool-approval-race-conditions.test.ts
+```
+
+**Results:**
+- Agent 1: Replaced timeouts with event-based waiting
+- Agent 2: Fixed event structure bug (threadId in wrong place)
+- Agent 3: Added wait for async tool execution to complete
+
+**Integration:** All fixes independent, no conflicts, full suite green
+
+**Time saved:** 3 problems solved in parallel vs sequentially
+
+## Key Benefits
+
+1. **Parallelization** - Multiple investigations happen simultaneously
+2. **Focus** - Each agent has narrow scope, less context to track
+3. **Independence** - Agents don't interfere with each other
+4. **Speed** - 3 problems solved in time of 1
+
+## Verification
+
+After agents return:
+1. **Review each summary** - Understand what changed
+2. **Check for conflicts** - Did agents edit same code?
+3. **Run full suite** - Verify all fixes work together
+4. **Spot check** - Agents can make systematic errors
+
+## Real-World Impact
+
+From debugging session (2025-10-03):
+- 6 failures across 3 files
+- 3 agents dispatched in parallel
+- All investigations completed concurrently
+- All fixes integrated successfully
+- Zero conflicts between agent changes

+name: executing-plans
+description: Use when you have a written implementation plan to execute in a separate session with review checkpoints
+---
+
+# Executing Plans
+
+## Overview
+
+Load plan, review critically, execute all tasks, report when complete.
+
+**Announce at start:** "I'm using the executing-plans skill to implement this plan."
+
+**Note:** Tell your human partner that Superpowers works much better with access to subagents. The quality of its work will be significantly higher if run on a platform with subagent support (such as Claude Code or Codex). If subagents are available, use superpowers:subagent-driven-development instead of this skill.
+
+## The Process
+
+### Step 1: Load and Review Plan
+1. Read plan file
+2. Review critically - identify any questions or concerns about the plan
+3. If concerns: Raise them with your human partner before starting
+4. If no concerns: Create TodoWrite and proceed
+
+### Step 2: Execute Tasks
+
+For each task:
+1. Mark as in_progress
+2. Follow each step exactly (plan has bite-sized steps)
+3. Run verifications as specified
+4. Mark as completed
+
+### Step 3: Complete Development
+
+After all tasks complete and verified:
+- Announce: "I'm using the finishing-a-development-branch skill to complete this work."
+- **REQUIRED SUB-SKILL:** Use superpowers:finishing-a-development-branch
+- Follow that skill to verify tests, present options, execute choice
+
+## When to Stop and Ask for Help
+
+**STOP executing immediately when:**
+- Hit a blocker (missing dependency, test fails, instruction unclear)
+- Plan has critical gaps preventing starting
+- You don't understand an instruction
+- Verification fails repeatedly
+
+**Ask for clarification rather than guessing.**
+
+## When to Revisit Earlier Steps
+
+**Return to Review (Step 1) when:**
+- Partner updates the plan based on your feedback
+- Fundamental approach needs rethinking
+
+**Don't force through blockers** - stop and ask.
+
+## Remember
+- Review plan critically first
+- Follow plan steps exactly
+- Don't skip verifications
+- Reference skills when plan says to
+- Stop when blocked, don't guess
+- Never start implementation on main/master branch without explicit user consent
+
+## Integration
+
+**Required workflow skills:**
+- **superpowers:using-git-worktrees** - Ensures isolated workspace (creates one or verifies existing)
+- **superpowers:writing-plans** - Creates the plan this skill executes
+- **superpowers:finishing-a-development-branch** - Complete development after all tasks

+name: finishing-a-development-branch
+description: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
+---
+
+# Finishing a Development Branch
+
+## Overview
+
+Guide completion of development work by presenting clear options and handling chosen workflow.
+
+**Core principle:** Verify tests → Detect environment → Present options → Execute choice → Clean up.
+
+**Announce at start:** "I'm using the finishing-a-development-branch skill to complete this work."
+
+## The Process
+
+### Step 1: Verify Tests
+
+**Before presenting options, verify tests pass:**
+
+```bash
+# Run project's test suite
+npm test / cargo test / pytest / go test ./...
+```
+
+**If tests fail:**
+```
+Tests failing (<N> failures). Must fix before completing:
+
+[Show failures]
+
+Cannot proceed with merge/PR until tests pass.
+```
+
+Stop. Don't proceed to Step 2.
+
+**If tests pass:** Continue to Step 2.
+
+### Step 2: Detect Environment
+
+**Determine workspace state before presenting options:**
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+```
+
+This determines which menu to show and how cleanup works:
+
+| State | Menu | Cleanup |
+|-------|------|---------|
+| `GIT_DIR == GIT_COMMON` (normal repo) | Standard 4 options | No worktree to clean up |
+| `GIT_DIR != GIT_COMMON`, named branch | Standard 4 options | Provenance-based (see Step 6) |
+| `GIT_DIR != GIT_COMMON`, detached HEAD | Reduced 3 options (no merge) | No cleanup (externally managed) |
+
+### Step 3: Determine Base Branch
+
+```bash
+# Try common base branches
+git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null
+```
+
+Or ask: "This branch split from main - is that correct?"
+
+### Step 4: Present Options
+
+**Normal repo and named-branch worktree — present exactly these 4 options:**
+
+```
+Implementation complete. What would you like to do?
+
+1. Merge back to <base-branch> locally
+2. Push and create a Pull Request
+3. Keep the branch as-is (I'll handle it later)
+4. Discard this work
+
+Which option?
+```
+
+**Detached HEAD — present exactly these 3 options:**
+
+```
+Implementation complete. You're on a detached HEAD (externally managed workspace).
+
+1. Push as new branch and create a Pull Request
+2. Keep as-is (I'll handle it later)
+3. Discard this work
+
+Which option?
+```
+
+**Don't add explanation** - keep options concise.
+
+### Step 5: Execute Choice
+
+#### Option 1: Merge Locally
+
+```bash
+# Get main repo root for CWD safety
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+cd "$MAIN_ROOT"
+
+# Merge first — verify success before removing anything
+git checkout <base-branch>
+git pull
+git merge <feature-branch>
+
+# Verify tests on merged result
+<test command>
+
+# Only after merge succeeds: cleanup worktree (Step 6), then delete branch
+```
+
+Then: Cleanup worktree (Step 6), then delete branch:
+
+```bash
+git branch -d <feature-branch>
+```
+
+#### Option 2: Push and Create PR
+
+```bash
+# Push branch
+git push -u origin <feature-branch>
+
+# Create PR
+gh pr create --title "<title>" --body "$(cat <<'EOF'
+## Summary
+<2-3 bullets of what changed>
+
+## Test Plan
+- [ ] <verification steps>
+EOF
+)"
+```
+
+**Do NOT clean up worktree** — user needs it alive to iterate on PR feedback.
+
+#### Option 3: Keep As-Is
+
+Report: "Keeping branch <name>. Worktree preserved at <path>."
+
+**Don't cleanup worktree.**
+
+#### Option 4: Discard
+
+**Confirm first:**
+```
+This will permanently delete:
+- Branch <name>
+- All commits: <commit-list>
+- Worktree at <path>
+
+Type 'discard' to confirm.
+```
+
+Wait for exact confirmation.
+
+If confirmed:
+```bash
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+cd "$MAIN_ROOT"
+```
+
+Then: Cleanup worktree (Step 6), then force-delete branch:
+```bash
+git branch -D <feature-branch>
+```
+
+### Step 6: Cleanup Workspace
+
+**Only runs for Options 1 and 4.** Options 2 and 3 always preserve the worktree.
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+WORKTREE_PATH=$(git rev-parse --show-toplevel)
+```
+
+**If `GIT_DIR == GIT_COMMON`:** Normal repo, no worktree to clean up. Done.
+
+**If worktree path is under `.worktrees/`, `worktrees/`, or `~/.config/superpowers/worktrees/`:** Superpowers created this worktree — we own cleanup.
+
+```bash
+MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
+cd "$MAIN_ROOT"
+git worktree remove "$WORKTREE_PATH"
+git worktree prune  # Self-healing: clean up any stale registrations
+```
+
+**Otherwise:** The host environment (harness) owns this workspace. Do NOT remove it. If your platform provides a workspace-exit tool, use it. Otherwise, leave the workspace in place.
+
+## Quick Reference
+
+| Option | Merge | Push | Keep Worktree | Cleanup Branch |
+|--------|-------|------|---------------|----------------|
+| 1. Merge locally | yes | - | - | yes |
+| 2. Create PR | - | yes | yes | - |
+| 3. Keep as-is | - | - | yes | - |
+| 4. Discard | - | - | - | yes (force) |
+
+## Common Mistakes
+
+**Skipping test verification**
+- **Problem:** Merge broken code, create failing PR
+- **Fix:** Always verify tests before offering options
+
+**Open-ended questions**
+- **Problem:** "What should I do next?" is ambiguous
+- **Fix:** Present exactly 4 structured options (or 3 for detached HEAD)
+
+**Cleaning up worktree for Option 2**
+- **Problem:** Remove worktree user needs for PR iteration
+- **Fix:** Only cleanup for Options 1 and 4
+
+**Deleting branch before removing worktree**
+- **Problem:** `git branch -d` fails because worktree still references the branch
+- **Fix:** Merge first, remove worktree, then delete branch
+
+**Running git worktree remove from inside the worktree**
+- **Problem:** Command fails silently when CWD is inside the worktree being removed
+- **Fix:** Always `cd` to main repo root before `git worktree remove`
+
+**Cleaning up harness-owned worktrees**
+- **Problem:** Removing a worktree the harness created causes phantom state
+- **Fix:** Only clean up worktrees under `.worktrees/`, `worktrees/`, or `~/.config/superpowers/worktrees/`
+
+**No confirmation for discard**
+- **Problem:** Accidentally delete work
+- **Fix:** Require typed "discard" confirmation
+
+## Red Flags
+
+**Never:**
+- Proceed with failing tests
+- Merge without verifying tests on result
+- Delete work without confirmation
+- Force-push without explicit request
+- Remove a worktree before confirming merge success
+- Clean up worktrees you didn't create (provenance check)
+- Run `git worktree remove` from inside the worktree
+
+**Always:**
+- Verify tests before offering options
+- Detect environment before presenting menu
+- Present exactly 4 options (or 3 for detached HEAD)
+- Get typed confirmation for Option 4
+- Clean up worktree for Options 1 & 4 only
+- `cd` to main repo root before worktree removal
+- Run `git worktree prune` after removal

+---
+
+Implement tasks from an OpenSpec change.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx-apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create the archive directory if it doesn't exist:
+   ```bash
+   mkdir -p openspec/changes/archive
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move the change directory to archive
+
+   ```bash
+   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)

+
+Archive multiple completed changes in a single operation.
+
+This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
+
+**Input**: None required (prompts for selection)
+
+**Steps**
+
+1. **Get active changes**
+
+   Run `openspec list --json` to get all active changes.
+
+   If no active changes exist, inform user and stop.
+
+2. **Prompt for change selection**
+
+   Use **AskUserQuestion tool** with multi-select to let user choose changes:
+   - Show each change with its schema
+   - Include an option for "All changes"
+   - Allow any number of selections (1+ works, 2+ is the typical use case)
+
+   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
+
+3. **Batch validation - gather status for all selected changes**
+
+   For each selected change, collect:
+
+   a. **Artifact status** - Run `openspec status --change "<name>" --json`
+      - Parse `schemaName` and `artifacts` list
+      - Note which artifacts are `done` vs other states
+
+   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
+      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
+      - If no tasks file exists, note as "No tasks"
+
+   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
+      - List which capability specs exist
+      - For each, extract requirement names (lines matching `### Requirement: <name>`)
+
+4. **Detect spec conflicts**
+
+   Build a map of `capability -> [changes that touch it]`:
+
+   ```
+   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
+   api  -> [change-c]            <- OK (only 1 change)
+   ```
+
+   A conflict exists when 2+ selected changes have delta specs for the same capability.
+
+5. **Resolve conflicts agentically**
+
+   **For each conflict**, investigate the codebase:
+
+   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
+
+   b. **Search the codebase** for implementation evidence:
+      - Look for code implementing requirements from each delta spec
+      - Check for related files, functions, or tests
+
+   c. **Determine resolution**:
+      - If only one change is actually implemented -> sync that one's specs
+      - If both implemented -> apply in chronological order (older first, newer overwrites)
+      - If neither implemented -> skip spec sync, warn user
+
+   d. **Record resolution** for each conflict:
+      - Which change's specs to apply
+      - In what order (if both)
+      - Rationale (what was found in codebase)
+
+6. **Show consolidated status table**
+
+   Display a table summarizing all changes:
+
+   ```
+   | Change              | Artifacts | Tasks | Specs   | Conflicts | Status |
+   |---------------------|-----------|-------|---------|-----------|--------|
+   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
+   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
+   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
+   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
+   ```
+
+   For conflicts, show the resolution:
+   ```
+   * Conflict resolution:
+     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
+   ```
+
+   For incomplete changes, show warnings:
+   ```
+   Warnings:
+   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
+   ```
+
+7. **Confirm batch operation**
+
+   Use **AskUserQuestion tool** with a single confirmation:
+
+   - "Archive N changes?" with options based on status
+   - Options might include:
+     - "Archive all N changes"
+     - "Archive only N ready changes (skip incomplete)"
+     - "Cancel"
+
+   If there are incomplete changes, make clear they'll be archived with warnings.
+
+8. **Execute archive for each confirmed change**
+
+   Process changes in the determined order (respecting conflict resolution):
+
+   a. **Sync specs** if delta specs exist:
+      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
+      - For conflicts, apply in resolved order
+      - Track if sync was done
+
+   b. **Perform the archive**:
+      ```bash
+      mkdir -p openspec/changes/archive
+      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
+      ```
+
+   c. **Track outcome** for each change:
+      - Success: archived successfully
+      - Failed: error during archive (record error)
+      - Skipped: user chose not to archive (if applicable)
+
+9. **Display summary**
+
+   Show final results:
+
+   ```
+   ## Bulk Archive Complete
+
+   Archived 3 changes:
+   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
+   - project-config -> archive/2026-01-19-project-config/
+   - add-oauth -> archive/2026-01-19-add-oauth/
+
+   Skipped 1 change:
+   - add-verify-skill (user chose not to archive incomplete)
+
+   Spec sync summary:
+   - 4 delta specs synced to main specs
+   - 1 conflict resolved (auth: applied both in chronological order)
+   ```
+
+   If any failures:
+   ```
+   Failed 1 change:
+   - some-change: Archive directory already exists
+   ```
+
+**Conflict Resolution Examples**
+
+Example 1: Only one implemented
+```
+Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
+
+Checking add-oauth:
+- Delta adds "OAuth Provider Integration" requirement
+- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
+
+Checking add-jwt:
+- Delta adds "JWT Token Handling" requirement
+- Searching codebase... no JWT implementation found
+
+Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
+```
+
+Example 2: Both implemented
+```
+Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
+
+Checking add-rest-api (created 2026-01-10):
+- Delta adds "REST Endpoints" requirement
+- Searching codebase... found src/api/rest.ts
+
+Checking add-graphql (created 2026-01-15):
+- Delta adds "GraphQL Schema" requirement
+- Searching codebase... found src/api/graphql.ts
+
+Resolution: Both implemented. Will apply add-rest-api specs first,
+then add-graphql specs (chronological order, newer takes precedence).
+```
+
+**Output On Success**
+
+```
+## Bulk Archive Complete
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+- <change-2> -> archive/YYYY-MM-DD-<change-2>/
+
+Spec sync summary:
+- N delta specs synced to main specs
+- No conflicts (or: M conflicts resolved)
+```
+
+**Output On Partial Success**
+
+```
+## Bulk Archive Complete (partial)
+
+Archived N changes:
+- <change-1> -> archive/YYYY-MM-DD-<change-1>/
+
+Skipped M changes:
+- <change-2> (user chose not to archive incomplete)
+
+Failed K changes:
+- <change-3>: Archive directory already exists
+```
+
+**Output When No Changes**
+
+```
+## No Changes to Archive
+
+No active changes found. Create a new change to get started.
+```
+
+**Guardrails**
+- Allow any number of changes (1+ is fine, 2+ is the typical use case)
+- Always prompt for selection, never auto-select
+- Detect spec conflicts early and resolve by checking codebase
+- When both changes are implemented, apply specs in chronological order
+- Skip spec sync only when implementation is missing (warn user)
+- Show clear per-change status before confirming
+- Use single confirmation for entire batch
+- Track and report all outcomes (success/skip/fail)
+- Preserve .openspec.yaml when moving to archive
+- Archive directory target uses current date: YYYY-MM-DD-<name>
+- If archive target exists, fail that change but continue with others

+Continue working on a change by creating the next artifact.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
+
+   Present the top 3-4 most recently modified changes as options, showing:
+   - Change name
+   - Schema (from `schema` field if present, otherwise "spec-driven")
+   - Status (e.g., "0/5 tasks", "complete", "no tasks")
+   - How recently it was modified (from `lastModified` field)
+
+   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check current status**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand current state. The response includes:
+   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
+   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
+   - `isComplete`: Boolean indicating if all artifacts are complete
+
+3. **Act based on status**:
+
+   ---
+
+   **If all artifacts are complete (`isComplete: true`)**:
+   - Congratulate the user
+   - Show final status including the schema used
+   - Suggest: "All artifacts created! You can now implement this change or archive it."
+   - STOP
+
+   ---
+
+   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
+   - Pick the FIRST artifact with `status: "ready"` from the status output
+   - Get its instructions:
+     ```bash
+     openspec instructions <artifact-id> --change "<name>" --json
+     ```
+   - Parse the JSON. The key fields are:
+     - `context`: Project background (constraints for you - do NOT include in output)
+     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+     - `template`: The structure to use for your output file
+     - `instruction`: Schema-specific guidance
+     - `outputPath`: Where to write the artifact
+     - `dependencies`: Completed artifacts to read for context
+   - **Create the artifact file**:
+     - Read any completed dependency files for context
+     - Use `template` as the structure - fill in its sections
+     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
+     - Write to the output path specified in instructions
+   - Show what was created and what's now unlocked
+   - STOP after creating ONE artifact
+
+   ---
+
+   **If no artifacts are ready (all blocked)**:
+   - This shouldn't happen with a valid schema
+   - Show status and suggest checking for issues
+
+4. **After creating an artifact, show progress**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After each invocation, show:
+- Which artifact was created
+- Schema workflow being used
+- Current progress (N/M complete)
+- What artifacts are now unlocked
+- Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
+
+**Artifact Creation Guidelines**
+
+The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
+
+Common artifact patterns:
+
+**spec-driven schema** (proposal → specs → design → tasks):
+- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
+  - The Capabilities section is critical - each capability listed will need a spec file.
+- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
+- **design.md**: Document technical decisions, architecture, and implementation approach.
+- **tasks.md**: Break down implementation into checkboxed tasks.
+
+For other schemas, follow the `instruction` field from the CLI output.
+
+**Guardrails**
+- Create ONE artifact per invocation
+- Always read dependency artifacts before creating a new one
+- Never skip artifacts or create out of order
+- If context is unclear, ask the user before creating
+- Verify the artifact file exists after writing before marking progress
+- Use the schema's artifact sequence, don't assume specific artifact names
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output

+description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.3.1"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Read existing artifacts for context**
+   - `openspec/changes/<name>/proposal.md`
+   - `openspec/changes/<name>/design.md`
+   - `openspec/changes/<name>/tasks.md`
+   - etc.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Handling Different Entry Points

+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+
+Fast-forward through artifact creation - generate everything needed to start implementation in one go.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "✓ Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx-apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, suggest continuing that change instead
+- Verify each artifact file exists after writing before proceeding to next

+
+Start a new change using the experimental artifact-driven approach.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Determine the workflow schema**
+
+   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
+
+   **Use a different schema only if the user mentions:**
+   - A specific schema name → use `--schema <name>`
+   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
+
+   **Otherwise**: Omit `--schema` to use the default.
+
+3. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   Add `--schema <name>` only if the user requested a specific workflow.
+   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
+
+4. **Show the artifact status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+   This shows which artifacts need to be created and which are ready (dependencies satisfied).
+
+5. **Get instructions for the first artifact**
+   The first artifact depends on the schema (e.g., `proposal` for spec-driven).
+   Check the status output to find the first artifact with status "ready".
+   ```bash
+   openspec instructions <first-artifact-id> --change "<name>"
+   ```
+   This outputs the template and context for creating the first artifact.
+
+6. **STOP and wait for user direction**
+
+**Output**
+
+After completing the steps, summarize:
+- Change name and location
+- Schema/workflow being used and its artifact sequence
+- Current status (0/N artifacts complete)
+- The template for the first artifact
+- Prompt: "Ready to create the first artifact? Just describe what this change is about and I'll draft it, or ask me to continue."
+
+**Guardrails**
+- Do NOT create any artifacts yet - just show the instructions
+- Do NOT advance beyond showing the first artifact template
+- If the name is invalid (not kebab-case), ask for a valid name
+- If a change with that name already exists, suggest continuing that change instead
+- Pass --schema if using a non-default workflow

+description: Guided onboarding for OpenSpec - walk through a complete workflow cycle with narration and real codebase work.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.3.1"
+---
+
+Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
+
+---
+
+## Preflight
+
+Before starting, check if the OpenSpec CLI is installed:
+
+```bash
+# Unix/macOS
+openspec --version 2>&1 || echo "CLI_NOT_INSTALLED"
+# Windows (PowerShell)
+# if (Get-Command openspec -ErrorAction SilentlyContinue) { openspec --version } else { echo "CLI_NOT_INSTALLED" }
+```
+
+**If CLI not installed:**
+> OpenSpec CLI is not installed. Install it first, then come back to `/opsx-onboard`.
+
+Stop here if not installed.
+
+---
+
+## Phase 1: Welcome
+
+Display:
+
+```
+## Welcome to OpenSpec!
+
+I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
+
+**What we'll do:**
+1. Pick a small, real task in your codebase
+2. Explore the problem briefly
+3. Create a change (the container for our work)
+4. Build the artifacts: proposal → specs → design → tasks
+5. Implement the tasks
+6. Archive the completed change
+
+**Time:** ~15-20 minutes
+
+Let's start by finding something to work on.
+```
+
+---
+
+## Phase 2: Task Selection
+
+### Codebase Analysis
+
+Scan the codebase for small improvement opportunities. Look for:
+
+1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
+2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
+3. **Functions without tests** - Cross-reference `src/` with test directories
+4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
+5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
+6. **Missing validation** - User input handlers without validation
+
+Also check recent git activity:
+```bash
+# Unix/macOS
+git log --oneline -10 2>/dev/null || echo "No git history"
+# Windows (PowerShell)
+# git log --oneline -10 2>$null; if ($LASTEXITCODE -ne 0) { echo "No git history" }
+```
+
+### Present Suggestions
+
+From your analysis, present 3-4 specific suggestions:
+
+```
+## Task Suggestions
+
+Based on scanning your codebase, here are some good starter tasks:
+
+**1. [Most promising task]**
+   Location: `src/path/to/file.ts:42`
+   Scope: ~1-2 files, ~20-30 lines
+   Why it's good: [brief reason]
+
+**2. [Second task]**
+   Location: `src/another/file.ts`
+   Scope: ~1 file, ~15 lines
+   Why it's good: [brief reason]
+
+**3. [Third task]**
+   Location: [location]
+   Scope: [estimate]
+   Why it's good: [brief reason]
+
+**4. Something else?**
+   Tell me what you'd like to work on.
+
+Which task interests you? (Pick a number or describe your own)
+```
+
+**If nothing found:** Fall back to asking what the user wants to build:
+> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
+
+### Scope Guardrail
+
+If the user picks or describes something too large (major feature, multi-day work):
+
+```
+That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
+
+For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
+
+**Options:**
+1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
+2. **Pick something else** - One of the other suggestions, or a different small task?
+3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
+
+What would you prefer?
+```
+
+Let the user override if they insist—this is a soft guardrail.
+
+---
+
+## Phase 3: Explore Demo
+
+Once a task is selected, briefly demonstrate explore mode:
+
+```
+Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
+```
+
+Spend 1-2 minutes investigating the relevant code:
+- Read the file(s) involved
+- Draw a quick ASCII diagram if it helps
+- Note any considerations
+
+```
+## Quick Exploration
+
+[Your brief analysis—what you found, any considerations]
+
+┌─────────────────────────────────────────┐
+│   [Optional: ASCII diagram if helpful]  │
+└─────────────────────────────────────────┘
+
+Explore mode (`/opsx-explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
+
+Now let's create a change to hold our work.
+```
+
+**PAUSE** - Wait for user acknowledgment before proceeding.
+
+---
+
+## Phase 4: Create the Change
+
+**EXPLAIN:**
+```
+## Creating a Change
+
+A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
+
+Let me create one for our task.
+```
+
+**DO:** Create the change with a derived kebab-case name:
+```bash
+openspec new change "<derived-name>"
+```
+
+**SHOW:**
+```
+Created: `openspec/changes/<name>/`
+
+The folder structure:
+```
+openspec/changes/<name>/
+├── proposal.md    ← Why we're doing this (empty, we'll fill it)
+├── design.md      ← How we'll build it (empty)
+├── specs/         ← Detailed requirements (empty)
+└── tasks.md       ← Implementation checklist (empty)
+```
+
+Now let's fill in the first artifact—the proposal.
+```
+
+---
+
+## Phase 5: Proposal
+
+**EXPLAIN:**
+```
+## The Proposal
+
+The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
+
+I'll draft one based on our task.
+```
+
+**DO:** Draft the proposal content (don't save yet):
+
+```
+Here's a draft proposal:
+
+---
+
+## Why
+
+[1-2 sentences explaining the problem/opportunity]
+
+## What Changes
+
+[Bullet points of what will be different]
+
+## Capabilities
+
+### New Capabilities
+- `<capability-name>`: [brief description]
+
+### Modified Capabilities
+<!-- If modifying existing behavior -->
+
+## Impact
+
+- `src/path/to/file.ts`: [what changes]
+- [other files if applicable]
+
+---
+
+Does this capture the intent? I can adjust before we save it.
+```
+
+**PAUSE** - Wait for user approval/feedback.
+
+After approval, save the proposal:
+```bash
+openspec instructions proposal --change "<name>" --json
+```
+Then write the content to `openspec/changes/<name>/proposal.md`.
+
+```
+Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
+
+Next up: specs.
+```
+
+---
+
+## Phase 6: Specs
+
+**EXPLAIN:**
+```
+## Specs
+
+Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
+
+For a small task like this, we might only need one spec file.
+```
+
+**DO:** Create the spec file:
+```bash
+# Unix/macOS
+mkdir -p openspec/changes/<name>/specs/<capability-name>
+# Windows (PowerShell)
+# New-Item -ItemType Directory -Force -Path "openspec/changes/<name>/specs/<capability-name>"
+```
+
+Draft the spec content:
+
+```
+Here's the spec:
+
+---
+
+## ADDED Requirements
+
+### Requirement: <Name>
+
+<Description of what the system should do>
+
+#### Scenario: <Scenario name>
+
+- **WHEN** <trigger condition>
+- **THEN** <expected outcome>
+- **AND** <additional outcome if needed>
+
+---
+
+This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
+```
+
+Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
+
+---
+
+## Phase 7: Design
+
+**EXPLAIN:**
+```
+## Design
+
+The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
+
+For small changes, this might be brief. That's fine—not every change needs deep design discussion.
+```
+
+**DO:** Draft design.md:
+
+```
+Here's the design:
+
+---
+
+## Context
+
+[Brief context about the current state]
+
+## Goals / Non-Goals
+
+**Goals:**
+- [What we're trying to achieve]
+
+**Non-Goals:**
+- [What's explicitly out of scope]
+
+## Decisions
+
+### Decision 1: [Key decision]
+
+[Explanation of approach and rationale]
+
+---
+
+For a small task, this captures the key decisions without over-engineering.
+```
+
+Save to `openspec/changes/<name>/design.md`.
+
+---
+
+## Phase 8: Tasks
+
+**EXPLAIN:**
+```
+## Tasks
+
+Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
+
+These should be small, clear, and in logical order.
+```
+
+**DO:** Generate tasks based on specs and design:
+
+```
+Here are the implementation tasks:
+
+---
+
+## 1. [Category or file]
+
+- [ ] 1.1 [Specific task]
+- [ ] 1.2 [Specific task]
+
+## 2. Verify
+
+- [ ] 2.1 [Verification step]
+
+---
+
+Each checkbox becomes a unit of work in the apply phase. Ready to implement?
+```
+
+**PAUSE** - Wait for user to confirm they're ready to implement.
+
+Save to `openspec/changes/<name>/tasks.md`.
+
+---
+
+## Phase 9: Apply (Implementation)
+
+**EXPLAIN:**
+```
+## Implementation
+
+Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
+```
+
+**DO:** For each task:
+
+1. Announce: "Working on task N: [description]"
+2. Implement the change in the codebase
+3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
+4. Mark complete in tasks.md: `- [ ]` → `- [x]`
+5. Brief status: "✓ Task N complete"
+
+Keep narration light—don't over-explain every line of code.
+
+After all tasks:
+
+```
+## Implementation Complete
+
+All tasks done:
+- [x] Task 1
+- [x] Task 2
+- [x] ...
+
+The change is implemented! One more step—let's archive it.
+```
+
+---
+
+## Phase 10: Archive
+
+**EXPLAIN:**
+```
+## Archiving
+
+When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
+
+Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
+```
+
+**DO:**
+```bash
+openspec archive "<name>"
+```
+
+**SHOW:**
+```
+Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
+
+The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
+```
+
+---
+
+## Phase 11: Recap & Next Steps
+
+```
+## Congratulations!
+
+You just completed a full OpenSpec cycle:
+
+1. **Explore** - Thought through the problem
+2. **New** - Created a change container
+3. **Proposal** - Captured WHY
+4. **Specs** - Defined WHAT in detail
+5. **Design** - Decided HOW
+6. **Tasks** - Broke it into steps
+7. **Apply** - Implemented the work
+8. **Archive** - Preserved the record
+
+This same rhythm works for any size change—a small fix or a major feature.

+
+## Graceful Exit Handling
+
+### User wants to stop mid-way
+
+If the user says they need to stop, want to pause, or seem disengaged:
+
+```
+No problem! Your change is saved at `openspec/changes/<name>/`.
+
+To pick up where we left off later:
+- `/opsx-continue <name>` - Resume artifact creation
+- `/opsx-apply <name>` - Jump to implementation (if tasks exist)
+
+The work won't be lost. Come back whenever you're ready.
+```
+
+Exit gracefully without pressure.
+
+### User just wants command reference
+
+If the user says they just want to see the commands or skip the tutorial:

+
+## Guardrails
+
+- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
+- **Keep narration light** during implementation—teach without lecturing
+- **Don't skip phases** even if the change is small—the goal is teaching the workflow
+- **Pause for acknowledgment** at marked points, but don't over-pause
+- **Handle exits gracefully**—never pressure the user to continue
+- **Use real codebase tasks**—don't simulate or use fake examples
+- **Adjust scope gently**—guide toward smaller tasks but respect user choice

+Propose a new change - create the change and generate all artifacts in one step.
+

+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx-apply
+
+---
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change at `openspec/changes/<name>/` with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `outputPath`: Where to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx-apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.3.1"
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Find delta specs**
+
+   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+3. **For each delta spec, apply changes to main specs**
+
+   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+4. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+description: Verify implementation matches change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.3.1"
+---
+
+Verify that an implementation matches the change artifacts (specs, tasks, design).
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have implementation tasks (tasks artifact exists).
+   Include the schema used for each change if available.
+   Mark changes with incomplete tasks as "(In Progress)".
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - Which artifacts exist for this change
+
+3. **Get the change directory and load artifacts**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns the change directory and `contextFiles` (artifact ID -> array of concrete file paths). Read all available artifacts from `contextFiles`.
+
+4. **Initialize verification report structure**
+
+   Create a report structure with three dimensions:
+   - **Completeness**: Track tasks and spec coverage
+   - **Correctness**: Track requirement implementation and scenario coverage
+   - **Coherence**: Track design adherence and pattern consistency
+
+   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
+
+5. **Verify Completeness**
+
+   **Task Completion**:
+   - If `contextFiles.tasks` exists, read every file path in it
+   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
+   - Count complete vs total tasks
+   - If incomplete tasks exist:
+     - Add CRITICAL issue for each incomplete task
+     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
+
+   **Spec Coverage**:
+   - If delta specs exist in `openspec/changes/<name>/specs/`:
+     - Extract all requirements (marked with "### Requirement:")
+     - For each requirement:
+       - Search codebase for keywords related to the requirement
+       - Assess if implementation likely exists
+     - If requirements appear unimplemented:
+       - Add CRITICAL issue: "Requirement not found: <requirement name>"
+       - Recommendation: "Implement requirement X: <description>"
+
+6. **Verify Correctness**
+
+   **Requirement Implementation Mapping**:
+   - For each requirement from delta specs:
+     - Search codebase for implementation evidence
+     - If found, note file paths and line ranges
+     - Assess if implementation matches requirement intent
+     - If divergence detected:
+       - Add WARNING: "Implementation may diverge from spec: <details>"
+       - Recommendation: "Review <file>:<lines> against requirement X"
+
+   **Scenario Coverage**:
+   - For each scenario in delta specs (marked with "#### Scenario:"):
+     - Check if conditions are handled in code
+     - Check if tests exist covering the scenario
+     - If scenario appears uncovered:
+       - Add WARNING: "Scenario not covered: <scenario name>"
+       - Recommendation: "Add test or implementation for scenario: <description>"
+
+7. **Verify Coherence**
+
+   **Design Adherence**:
+   - If `contextFiles.design` exists:
+     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
+     - Verify implementation follows those decisions
+     - If contradiction detected:
+       - Add WARNING: "Design decision not followed: <decision>"
+       - Recommendation: "Update implementation or revise design.md to match reality"
+   - If no design.md: Skip design adherence check, note "No design.md to verify against"
+
+   **Code Pattern Consistency**:
+   - Review new code for consistency with project patterns
+   - Check file naming, directory structure, coding style
+   - If significant deviations found:
+     - Add SUGGESTION: "Code pattern deviation: <details>"
+     - Recommendation: "Consider following project pattern: <example>"
+
+8. **Generate Verification Report**
+
+   **Summary Scorecard**:
+   ```
+   ## Verification Report: <change-name>
+
+   ### Summary
+   | Dimension    | Status           |
+   |--------------|------------------|
+   | Completeness | X/Y tasks, N reqs|
+   | Correctness  | M/N reqs covered |
+   | Coherence    | Followed/Issues  |
+   ```
+
+   **Issues by Priority**:
+
+   1. **CRITICAL** (Must fix before archive):
+      - Incomplete tasks
+      - Missing requirement implementations
+      - Each with specific, actionable recommendation
+
+   2. **WARNING** (Should fix):
+      - Spec/design divergences
+      - Missing scenario coverage
+      - Each with specific recommendation
+
+   3. **SUGGESTION** (Nice to fix):
+      - Pattern inconsistencies
+      - Minor improvements
+      - Each with specific recommendation
+
+   **Final Assessment**:
+   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
+   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
+   - If all clear: "All checks passed. Ready for archive."
+
+**Verification Heuristics**
+
+- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
+- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
+- **Coherence**: Look for glaring inconsistencies, don't nitpick style
+- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
+- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
+
+**Graceful Degradation**
+
+- If only tasks.md exists: verify task completion only, skip spec/design checks
+- If tasks + specs exist: verify completeness and correctness, skip design
+- If full artifacts: verify all three dimensions
+- Always note which checks were skipped and why
+
+**Output Format**
+
+Use clear markdown with:
+- Table for summary scorecard
+- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
+- Code references in format: `file.ts:123`
+- Specific, actionable recommendations
+- No vague suggestions like "consider reviewing"

+name: receiving-code-review
+description: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
+---
+
+# Code Review Reception
+
+## Overview
+
+Code review requires technical evaluation, not emotional performance.
+
+**Core principle:** Verify before implementing. Ask before assuming. Technical correctness over social comfort.
+
+## The Response Pattern
+
+```
+WHEN receiving code review feedback:
+
+1. READ: Complete feedback without reacting
+2. UNDERSTAND: Restate requirement in own words (or ask)
+3. VERIFY: Check against codebase reality
+4. EVALUATE: Technically sound for THIS codebase?
+5. RESPOND: Technical acknowledgment or reasoned pushback
+6. IMPLEMENT: One item at a time, test each
+```
+
+## Forbidden Responses
+
+**NEVER:**
+- "You're absolutely right!" (explicit CLAUDE.md violation)
+- "Great point!" / "Excellent feedback!" (performative)
+- "Let me implement that now" (before verification)
+
+**INSTEAD:**
+- Restate the technical requirement
+- Ask clarifying questions
+- Push back with technical reasoning if wrong
+- Just start working (actions > words)
+
+## Handling Unclear Feedback
+
+```
+IF any item is unclear:
+  STOP - do not implement anything yet
+  ASK for clarification on unclear items
+
+WHY: Items may be related. Partial understanding = wrong implementation.
+```
+
+**Example:**
+```
+your human partner: "Fix 1-6"
+You understand 1,2,3,6. Unclear on 4,5.
+
+❌ WRONG: Implement 1,2,3,6 now, ask about 4,5 later
+✅ RIGHT: "I understand items 1,2,3,6. Need clarification on 4 and 5 before proceeding."
+```
+
+## Source-Specific Handling
+
+### From your human partner
+- **Trusted** - implement after understanding
+- **Still ask** if scope unclear
+- **No performative agreement**
+- **Skip to action** or technical acknowledgment
+
+### From External Reviewers
+```
+BEFORE implementing:
+  1. Check: Technically correct for THIS codebase?
+  2. Check: Breaks existing functionality?
+  3. Check: Reason for current implementation?
+  4. Check: Works on all platforms/versions?
+  5. Check: Does reviewer understand full context?
+
+IF suggestion seems wrong:
+  Push back with technical reasoning
+
+IF can't easily verify:
+  Say so: "I can't verify this without [X]. Should I [investigate/ask/proceed]?"
+
+IF conflicts with your human partner's prior decisions:
+  Stop and discuss with your human partner first
+```
+
+**your human partner's rule:** "External feedback - be skeptical, but check carefully"
+
+## YAGNI Check for "Professional" Features
+
+```
+IF reviewer suggests "implementing properly":
+  grep codebase for actual usage
+
+  IF unused: "This endpoint isn't called. Remove it (YAGNI)?"
+  IF used: Then implement properly
+```
+
+**your human partner's rule:** "You and reviewer both report to me. If we don't need this feature, don't add it."
+
+## Implementation Order
+
+```
+FOR multi-item feedback:
+  1. Clarify anything unclear FIRST
+  2. Then implement in this order:
+     - Blocking issues (breaks, security)
+     - Simple fixes (typos, imports)
+     - Complex fixes (refactoring, logic)
+  3. Test each fix individually
+  4. Verify no regressions
+```
+
+## When To Push Back
+
+Push back when:
+- Suggestion breaks existing functionality
+- Reviewer lacks full context
+- Violates YAGNI (unused feature)
+- Technically incorrect for this stack
+- Legacy/compatibility reasons exist
+- Conflicts with your human partner's architectural decisions
+
+**How to push back:**
+- Use technical reasoning, not defensiveness
+- Ask specific questions
+- Reference working tests/code
+- Involve your human partner if architectural
+
+**Signal if uncomfortable pushing back out loud:** "Strange things are afoot at the Circle K"
+
+## Acknowledging Correct Feedback
+
+When feedback IS correct:
+```
+✅ "Fixed. [Brief description of what changed]"
+✅ "Good catch - [specific issue]. Fixed in [location]."
+✅ [Just fix it and show in the code]
+
+❌ "You're absolutely right!"
+❌ "Great point!"
+❌ "Thanks for catching that!"
+❌ "Thanks for [anything]"
+❌ ANY gratitude expression
+```
+
+**Why no thanks:** Actions speak. Just fix it. The code itself shows you heard the feedback.
+
+**If you catch yourself about to write "Thanks":** DELETE IT. State the fix instead.
+
+## Gracefully Correcting Your Pushback
+
+If you pushed back and were wrong:
+```
+✅ "You were right - I checked [X] and it does [Y]. Implementing now."
+✅ "Verified this and you're correct. My initial understanding was wrong because [reason]. Fixing."
+
+❌ Long apology
+❌ Defending why you pushed back
+❌ Over-explaining
+```
+
+State the correction factually and move on.
+
+## Common Mistakes
+
+| Mistake | Fix |
+|---------|-----|
+| Performative agreement | State requirement or just act |
+| Blind implementation | Verify against codebase first |
+| Batch without testing | One at a time, test each |
+| Assuming reviewer is right | Check if breaks things |
+| Avoiding pushback | Technical correctness > comfort |
+| Partial implementation | Clarify all items first |
+| Can't verify, proceed anyway | State limitation, ask for direction |
+
+## Real Examples
+
+**Performative Agreement (Bad):**
+```
+Reviewer: "Remove legacy code"
+❌ "You're absolutely right! Let me remove that..."
+```
+
+**Technical Verification (Good):**
+```
+Reviewer: "Remove legacy code"
+✅ "Checking... build target is 10.15+, this API needs 13+. Need legacy for backward compat. Current impl has wrong bundle ID - fix it or drop pre-13 support?"
+```
+
+**YAGNI (Good):**
+```
+Reviewer: "Implement proper metrics tracking with database, date filters, CSV export"
+✅ "Grepped codebase - nothing calls this endpoint. Remove it (YAGNI)? Or is there usage I'm missing?"
+```
+
+**Unclear Item (Good):**
+```
+your human partner: "Fix items 1-6"
+You understand 1,2,3,6. Unclear on 4,5.
+✅ "Understand 1,2,3,6. Need clarification on 4 and 5 before implementing."
+```
+
+## GitHub Thread Replies
+
+When replying to inline review comments on GitHub, reply in the comment thread (`gh api repos/{owner}/{repo}/pulls/{pr}/comments/{id}/replies`), not as a top-level PR comment.
+
+## The Bottom Line
+
+**External feedback = suggestions to evaluate, not orders to follow.**
+
+Verify. Question. Then implement.
+
+No performative agreement. Technical rigor always.

+---
+
+# Requesting Code Review
+
+Dispatch a code reviewer subagent to catch issues before they cascade. The reviewer gets precisely crafted context for evaluation — never your session's history. This keeps the reviewer focused on the work product, not your thought process, and preserves your own context for continued work.
+
+**Core principle:** Review early, review often.
+
+## When to Request Review
+
+**Mandatory:**
+- After each task in subagent-driven development
+- After completing major feature
+- Before merge to main
+
+**Optional but valuable:**
+- When stuck (fresh perspective)
+- Before refactoring (baseline check)
+- After fixing complex bug
+
+## How to Request
+
+**1. Get git SHAs:**
+```bash
+BASE_SHA=$(git rev-parse HEAD~1)  # or origin/main
+HEAD_SHA=$(git rev-parse HEAD)
+```
+
+**2. Dispatch code reviewer subagent:**
+
+Use Task tool with `general-purpose` type, fill template at `code-reviewer.md`
+
+**Placeholders:**
+- `{DESCRIPTION}` - Brief summary of what you built
+- `{PLAN_OR_REQUIREMENTS}` - What it should do
+- `{BASE_SHA}` - Starting commit
+- `{HEAD_SHA}` - Ending commit
+
+**3. Act on feedback:**
+- Fix Critical issues immediately
+- Fix Important issues before proceeding
+- Note Minor issues for later
+- Push back if reviewer is wrong (with reasoning)
+
+## Example
+
+```
+[Just completed Task 2: Add verification function]
+
+You: Let me request code review before proceeding.
+
+BASE_SHA=$(git log --oneline | grep "Task 1" | head -1 | awk '{print $1}')
+HEAD_SHA=$(git rev-parse HEAD)
+
+[Dispatch code reviewer subagent]
+  DESCRIPTION: Added verifyIndex() and repairIndex() with 4 issue types
+  PLAN_OR_REQUIREMENTS: Task 2 from docs/superpowers/plans/deployment-plan.md
+  BASE_SHA: a7981ec
+  HEAD_SHA: 3df7661
+
+[Subagent returns]:
+  Strengths: Clean architecture, real tests
+  Issues:
+    Important: Missing progress indicators
+    Minor: Magic number (100) for reporting interval
+  Assessment: Ready to proceed
+
+You: [Fix progress indicators]
+[Continue to Task 3]
+```
+
+## Integration with Workflows
+
+**Subagent-Driven Development:**
+- Review after EACH task
+- Catch issues before they compound
+- Fix before moving to next task
+
+**Executing Plans:**
+- Review after each task or at natural checkpoints
+- Get feedback, apply, continue
+
+**Ad-Hoc Development:**
+- Review before merge
+- Review when stuck
+
+## Red Flags
+
+**Never:**
+- Skip review because "it's simple"
+- Ignore Critical issues
+- Proceed with unfixed Important issues
+- Argue with valid technical feedback
+
+**If reviewer wrong:**
+- Push back with technical reasoning
+- Show code/tests that prove it works
+- Request clarification
+
+See template at: requesting-code-review/code-reviewer.md

+# Code Reviewer Prompt Template
+
+Use this template when dispatching a code reviewer subagent.
+
+**Purpose:** Review completed work against requirements and code quality standards before it cascades into more work.
+
+```
+Task tool (general-purpose):
+  description: "Review code changes"
+  prompt: |
+    You are a Senior Code Reviewer with expertise in software architecture,
+    design patterns, and best practices. Your job is to review completed work
+    against its plan or requirements and identify issues before they cascade.
+
+    ## What Was Implemented
+
+    {DESCRIPTION}
+
+    ## Requirements / Plan
+
+    {PLAN_OR_REQUIREMENTS}
+
+    ## Git Range to Review
+
+    **Base:** {BASE_SHA}
+    **Head:** {HEAD_SHA}
+
+    ```bash
+    git diff --stat {BASE_SHA}..{HEAD_SHA}
+    git diff {BASE_SHA}..{HEAD_SHA}
+    ```
+
+    ## What to Check
+
+    **Plan alignment:**
+    - Does the implementation match the plan / requirements?
+    - Are deviations justified improvements, or problematic departures?
+    - Is all planned functionality present?
+
+    **Code quality:**
+    - Clean separation of concerns?
+    - Proper error handling?
+    - Type safety where applicable?
+    - DRY without premature abstraction?
+    - Edge cases handled?
+
+    **Architecture:**
+    - Sound design decisions?
+    - Reasonable scalability and performance?
+    - Security concerns?
+    - Integrates cleanly with surrounding code?
+
+    **Testing:**
+    - Tests verify real behavior, not mocks?
+    - Edge cases covered?
+    - Integration tests where they matter?
+    - All tests passing?
+
+    **Production readiness:**
+    - Migration strategy if schema changed?
+    - Backward compatibility considered?
+    - Documentation complete?
+    - No obvious bugs?
+
+    ## Calibration
+
+    Categorize issues by actual severity. Not everything is Critical.
+    Acknowledge what was done well before listing issues — accurate praise
+    helps the implementer trust the rest of the feedback.
+
+    If you find significant deviations from the plan, flag them specifically
+    so the implementer can confirm whether the deviation was intentional.
+    If you find issues with the plan itself rather than the implementation,
+    say so.
+
+    ## Output Format
+
+    ### Strengths
+    [What's well done? Be specific.]
+
+    ### Issues
+
+    #### Critical (Must Fix)
+    [Bugs, security issues, data loss risks, broken functionality]
+
+    #### Important (Should Fix)
+    [Architecture problems, missing features, poor error handling, test gaps]
+
+    #### Minor (Nice to Have)
+    [Code style, optimization opportunities, documentation polish]
+
+    For each issue:
+    - File:line reference
+    - What's wrong
+    - Why it matters
+    - How to fix (if not obvious)
+
+    ### Recommendations
+    [Improvements for code quality, architecture, or process]
+
+    ### Assessment
+
+    **Ready to merge?** [Yes | No | With fixes]
+
+    **Reasoning:** [1-2 sentence technical assessment]
+
+    ## Critical Rules
+
+    **DO:**
+    - Categorize by actual severity
+    - Be specific (file:line, not vague)
+    - Explain WHY each issue matters
+    - Acknowledge strengths
+    - Give a clear verdict
+
+    **DON'T:**
+    - Say "looks good" without checking
+    - Mark nitpicks as Critical
+    - Give feedback on code you didn't actually read
+    - Be vague ("improve error handling")
+    - Avoid giving a clear verdict
+```
+
+**Placeholders:**
+- `{DESCRIPTION}` — brief summary of what was built
+- `{PLAN_OR_REQUIREMENTS}` — what it should do (plan file path, task text, or requirements)
+- `{BASE_SHA}` — starting commit
+- `{HEAD_SHA}` — ending commit
+
+**Reviewer returns:** Strengths, Issues (Critical / Important / Minor), Recommendations, Assessment
+
+## Example Output
+
+```
+### Strengths
+- Clean database schema with proper migrations (db.ts:15-42)
+- Comprehensive test coverage (18 tests, all edge cases)
+- Good error handling with fallbacks (summarizer.ts:85-92)
+
+### Issues
+
+#### Important
+1. **Missing help text in CLI wrapper**
+   - File: index-conversations:1-31
+   - Issue: No --help flag, users won't discover --concurrency
+   - Fix: Add --help case with usage examples
+
+2. **Date validation missing**
+   - File: search.ts:25-27
+   - Issue: Invalid dates silently return no results
+   - Fix: Validate ISO format, throw error with example
+
+#### Minor
+1. **Progress indicators**
+   - File: indexer.ts:130
+   - Issue: No "X of Y" counter for long operations
+   - Impact: Users don't know how long to wait
+
+### Recommendations
+- Add progress reporting for user experience
+- Consider config file for excluded projects (portability)
+
+### Assessment
+
+**Ready to merge: With fixes**
+
+**Reasoning:** Core implementation is solid with good architecture and tests. Important issues (help text, date validation) are easily fixed and don't affect core functionality.

+description: Use when executing implementation plans with independent tasks in the current session
+---
+
+# Subagent-Driven Development
+
+Execute plan by dispatching fresh subagent per task, with two-stage review after each: spec compliance review first, then code quality review.
+
+**Why subagents:** You delegate tasks to specialized agents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.
+
+**Core principle:** Fresh subagent per task + two-stage review (spec then quality) = high quality, fast iteration
+
+**Continuous execution:** Do not pause to check in with your human partner between tasks. Execute all tasks from the plan without stopping. The only reasons to stop are: BLOCKED status you cannot resolve, ambiguity that genuinely prevents progress, or all tasks complete. "Should I continue?" prompts and progress summaries waste their time — they asked you to execute the plan, so execute it.
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Have implementation plan?" [shape=diamond];
+    "Tasks mostly independent?" [shape=diamond];
+    "Stay in this session?" [shape=diamond];
+    "subagent-driven-development" [shape=box];
+    "executing-plans" [shape=box];
+    "Manual execution or brainstorm first" [shape=box];
+
+    "Have implementation plan?" -> "Tasks mostly independent?" [label="yes"];
+    "Have implementation plan?" -> "Manual execution or brainstorm first" [label="no"];
+    "Tasks mostly independent?" -> "Stay in this session?" [label="yes"];
+    "Tasks mostly independent?" -> "Manual execution or brainstorm first" [label="no - tightly coupled"];
+    "Stay in this session?" -> "subagent-driven-development" [label="yes"];
+    "Stay in this session?" -> "executing-plans" [label="no - parallel session"];
+}
+```
+
+**vs. Executing Plans (parallel session):**
+- Same session (no context switch)
+- Fresh subagent per task (no context pollution)
+- Two-stage review after each task: spec compliance first, then code quality
+- Faster iteration (no human-in-loop between tasks)
+

+}
+```
+
+## Model Selection
+
+Use the least powerful model that can handle each role to conserve cost and increase speed.
+
+**Mechanical implementation tasks** (isolated functions, clear specs, 1-2 files): use a fast, cheap model. Most implementation tasks are mechanical when the plan is well-specified.
+
+**Integration and judgment tasks** (multi-file coordination, pattern matching, debugging): use a standard model.
+
+**Architecture, design, and review tasks**: use the most capable available model.
+
+**Task complexity signals:**
+- Touches 1-2 files with a complete spec → cheap model
+- Touches multiple files with integration concerns → standard model
+- Requires design judgment or broad codebase understanding → most capable model
+
+## Handling Implementer Status
+
+Implementer subagents report one of four statuses. Handle each appropriately:
+
+**DONE:** Proceed to spec compliance review.
+
+**DONE_WITH_CONCERNS:** The implementer completed the work but flagged doubts. Read the concerns before proceeding. If the concerns are about correctness or scope, address them before review. If they're observations (e.g., "this file is getting large"), note them and proceed to review.
+
+**NEEDS_CONTEXT:** The implementer needs information that wasn't provided. Provide the missing context and re-dispatch.
+
+**BLOCKED:** The implementer cannot complete the task. Assess the blocker:
+1. If it's a context problem, provide more context and re-dispatch with the same model
+2. If the task requires more reasoning, re-dispatch with a more capable model
+3. If the task is too large, break it into smaller pieces
+4. If the plan itself is wrong, escalate to the human
+
+**Never** ignore an escalation or force the same model to retry without changes. If the implementer said it's stuck, something needs to change.
+
+## Prompt Templates
+
+- `./implementer-prompt.md` - Dispatch implementer subagent
+- `./spec-reviewer-prompt.md` - Dispatch spec compliance reviewer subagent
+- `./code-quality-reviewer-prompt.md` - Dispatch code quality reviewer subagent
+
+## Example Workflow
+
+```
+You: I'm using Subagent-Driven Development to execute this plan.
+
+[Read plan file once: docs/superpowers/plans/feature-plan.md]
+[Extract all 5 tasks with full text and context]
+[Create TodoWrite with all tasks]
+
+Task 1: Hook installation script
+
+[Get Task 1 text and context (already extracted)]
+[Dispatch implementation subagent with full task text + context]
+
+Implementer: "Before I begin - should the hook be installed at user or system level?"
+
+You: "User level (~/.config/superpowers/hooks/)"
+
+Implementer: "Got it. Implementing now..."
+[Later] Implementer:
+  - Implemented install-hook command
+  - Added tests, 5/5 passing
+  - Self-review: Found I missed --force flag, added it
+  - Committed
+
+[Dispatch spec compliance reviewer]
+Spec reviewer: ✅ Spec compliant - all requirements met, nothing extra
+
+[Get git SHAs, dispatch code quality reviewer]
+Code reviewer: Strengths: Good test coverage, clean. Issues: None. Approved.
+
+[Mark Task 1 complete]
+
+Task 2: Recovery modes
+
+[Get Task 2 text and context (already extracted)]
+[Dispatch implementation subagent with full task text + context]
+
+Implementer: [No questions, proceeds]
+Implementer:
+  - Added verify/repair modes
+  - 8/8 tests passing
+  - Self-review: All good
+  - Committed
+
+[Dispatch spec compliance reviewer]
+Spec reviewer: ❌ Issues:
+  - Missing: Progress reporting (spec says "report every 100 items")
+  - Extra: Added --json flag (not requested)
+
+[Implementer fixes issues]
+Implementer: Removed --json flag, added progress reporting
+
+[Spec reviewer reviews again]
+Spec reviewer: ✅ Spec compliant now
+
+[Dispatch code quality reviewer]
+Code reviewer: Strengths: Solid. Issues (Important): Magic number (100)
+
+[Implementer fixes]
+Implementer: Extracted PROGRESS_INTERVAL constant
+
+[Code reviewer reviews again]
+Code reviewer: ✅ Approved
+
+[Mark Task 2 complete]
+
+...
+
+[After all tasks]
+[Dispatch final code-reviewer]
+Final reviewer: All requirements met, ready to merge
+
+Done!
+```
+
+## Advantages
+
+**vs. Manual execution:**
+- Subagents follow TDD naturally
+- Fresh context per task (no confusion)
+- Parallel-safe (subagents don't interfere)
+- Subagent can ask questions (before AND during work)
+
+**vs. Executing Plans:**
+- Same session (no handoff)
+- Continuous progress (no waiting)
+- Review checkpoints automatic
+
+**Efficiency gains:**
+- No file reading overhead (controller provides full text)
+- Controller curates exactly what context is needed
+- Subagent gets complete information upfront
+- Questions surfaced before work begins (not after)
+
+**Quality gates:**
+- Self-review catches issues before handoff
+- Two-stage review: spec compliance, then code quality
+- Review loops ensure fixes actually work
+- Spec compliance prevents over/under-building
+- Code quality ensures implementation is well-built
+
+**Cost:**
+- More subagent invocations (implementer + 2 reviewers per task)
+- Controller does more prep work (extracting all tasks upfront)
+- Review loops add iterations
+- But catches issues early (cheaper than debugging later)
+
+## Red Flags
+
+**Never:**
+- Start implementation on main/master branch without explicit user consent
+- Skip reviews (spec compliance OR code quality)
+- Proceed with unfixed issues
+- Dispatch multiple implementation subagents in parallel (conflicts)
+- Make subagent read plan file (provide full text instead)
+- Skip scene-setting context (subagent needs to understand where task fits)
+- Ignore subagent questions (answer before letting them proceed)
+- Accept "close enough" on spec compliance (spec reviewer found issues = not done)
+- Skip review loops (reviewer found issues = implementer fixes = review again)
+- Let implementer self-review replace actual review (both are needed)
+- **Start code quality review before spec compliance is ✅** (wrong order)
+- Move to next task while either review has open issues
+
+**If subagent asks questions:**
+- Answer clearly and completely
+- Provide additional context if needed
+- Don't rush them into implementation
+
+**If reviewer finds issues:**
+- Implementer (same subagent) fixes them
+- Reviewer reviews again
+- Repeat until approved
+- Don't skip the re-review
+
+**If subagent fails task:**
+- Dispatch fix subagent with specific instructions
+- Don't try to fix manually (context pollution)
+
+## Integration
+
+**Required workflow skills:**
+- **superpowers:using-git-worktrees** - Ensures isolated workspace (creates one or verifies existing)
+- **superpowers:writing-plans** - Creates the plan this skill executes
+- **superpowers:requesting-code-review** - Code review template for reviewer subagents
+- **superpowers:finishing-a-development-branch** - Complete development after all tasks
+
+**Subagents should use:**
+- **superpowers:test-driven-development** - Subagents follow TDD for each task
+
+**Alternative workflow:**
+- **superpowers:executing-plans** - Use for parallel session instead of same-session execution

+# Code Quality Reviewer Prompt Template
+
+Use this template when dispatching a code quality reviewer subagent.
+
+**Purpose:** Verify implementation is well-built (clean, tested, maintainable)
+
+**Only dispatch after spec compliance review passes.**
+
+```
+Task tool (general-purpose):
+  Use template at requesting-code-review/code-reviewer.md

+  DESCRIPTION: [task summary, from implementer's report]
+  PLAN_OR_REQUIREMENTS: Task N from [plan-file]
+  BASE_SHA: [commit before task]
+  HEAD_SHA: [current commit]
+```
+
+**In addition to standard code quality concerns, the reviewer should check:**
+- Does each file have one clear responsibility with a well-defined interface?
+- Are units decomposed so they can be understood and tested independently?
+- Is the implementation following the file structure from the plan?
+- Did this implementation create new files that are already large, or significantly grow existing files? (Don't flag pre-existing file sizes — focus on what this change contributed.)
+
+**Code reviewer returns:** Strengths, Issues (Critical/Important/Minor), Assessment

+    2. Write tests (following TDD if task says to)
+    3. Verify implementation works
+    4. Commit your work
+    5. Self-review (see below)
+    6. Report back
+
+    Work from: [directory]
+
+    **While you work:** If you encounter something unexpected or unclear, **ask questions**.
+    It's always OK to pause and clarify. Don't guess or make assumptions.
+
+    ## Code Organization
+
+    You reason best about code you can hold in context at once, and your edits are more
+    reliable when files are focused. Keep this in mind:
+    - Follow the file structure defined in the plan
+    - Each file should have one clear responsibility with a well-defined interface
+    - If a file you're creating is growing beyond the plan's intent, stop and report
+      it as DONE_WITH_CONCERNS — don't split files on your own without plan guidance
+    - If an existing file you're modifying is already large or tangled, work carefully
+      and note it as a concern in your report
+    - In existing codebases, follow established patterns. Improve code you're touching
+      the way a good developer would, but don't restructure things outside your task.
+
+    ## When You're in Over Your Head
+
+    It is always OK to stop and say "this is too hard for me." Bad work is worse than
+    no work. You will not be penalized for escalating.
+
+    **STOP and escalate when:**
+    - The task requires architectural decisions with multiple valid approaches
+    - You need to understand code beyond what was provided and can't find clarity
+    - You feel uncertain about whether your approach is correct
+    - The task involves restructuring existing code in ways the plan didn't anticipate
+    - You've been reading file after file trying to understand the system without progress
+
+    **How to escalate:** Report back with status BLOCKED or NEEDS_CONTEXT. Describe
+    specifically what you're stuck on, what you've tried, and what kind of help you need.
+    The controller can provide more context, re-dispatch with a more capable model,
+    or break the task into smaller pieces.
+
+    ## Before Reporting Back: Self-Review
+
+    Review your work with fresh eyes. Ask yourself:
+
+    **Completeness:**
+    - Did I fully implement everything in the spec?
+    - Did I miss any requirements?
+    - Are there edge cases I didn't handle?
+
+    **Quality:**
+    - Is this my best work?
+    - Are names clear and accurate (match what things do, not how they work)?
+    - Is the code clean and maintainable?
+
+    **Discipline:**
+    - Did I avoid overbuilding (YAGNI)?
+    - Did I only build what was requested?
+    - Did I follow existing patterns in the codebase?
+
+    **Testing:**
+    - Do tests actually verify behavior (not just mock behavior)?
+    - Did I follow TDD if required?
+    - Are tests comprehensive?
+
+    If you find issues during self-review, fix them now before reporting.
+
+    ## Report Format
+
+    When done, report:
+    - **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
+    - What you implemented (or what you attempted, if blocked)
+    - What you tested and test results
+    - Files changed
+    - Self-review findings (if any)
+    - Any issues or concerns
+
+    Use DONE_WITH_CONCERNS if you completed the work but have doubts about correctness.
+    Use BLOCKED if you cannot complete the task. Use NEEDS_CONTEXT if you need
+    information that wasn't provided. Never silently produce work you're unsure about.

+# Spec Compliance Reviewer Prompt Template
+
+Use this template when dispatching a spec compliance reviewer subagent.
+
+**Purpose:** Verify implementer built what was requested (nothing more, nothing less)
+
+```
+Task tool (general-purpose):
+  description: "Review spec compliance for Task N"
+  prompt: |
+    You are reviewing whether an implementation matches its specification.
+
+    ## What Was Requested
+
+    [FULL TEXT of task requirements]
+
+    ## What Implementer Claims They Built
+
+    [From implementer's report]
+
+    ## CRITICAL: Do Not Trust the Report
+
+    The implementer finished suspiciously quickly. Their report may be incomplete,
+    inaccurate, or optimistic. You MUST verify everything independently.
+
+    **DO NOT:**
+    - Take their word for what they implemented
+    - Trust their claims about completeness
+    - Accept their interpretation of requirements
+
+    **DO:**
+    - Read the actual code they wrote
+    - Compare actual implementation to requirements line by line
+    - Check for missing pieces they claimed to implement
+    - Look for extra features they didn't mention
+
+    ## Your Job
+
+    Read the implementation code and verify:
+
+    **Missing requirements:**
+    - Did they implement everything that was requested?
+    - Are there requirements they skipped or missed?
+    - Did they claim something works but didn't actually implement it?
+
+    **Extra/unneeded work:**
+    - Did they build things that weren't requested?
+    - Did they over-engineer or add unnecessary features?
+    - Did they add "nice to haves" that weren't in spec?
+
+    **Misunderstandings:**
+    - Did they interpret requirements differently than intended?
+    - Did they solve the wrong problem?
+    - Did they implement the right feature but wrong way?
+
+    **Verify by reading code, not by trusting report.**
+
+    Report:
+    - ✅ Spec compliant (if everything matches after code inspection)
+    - ❌ Issues found: [list specifically what's missing or extra, with file:line references]

+# Creation Log: Systematic Debugging Skill
+
+Reference example of extracting, structuring, and bulletproofing a critical skill.
+
+## Source Material
+
+Extracted debugging framework from `~/.claude/CLAUDE.md`:
+- 4-phase systematic process (Investigation → Pattern Analysis → Hypothesis → Implementation)
+- Core mandate: ALWAYS find root cause, NEVER fix symptoms
+- Rules designed to resist time pressure and rationalization
+
+## Extraction Decisions
+
+**What to include:**
+- Complete 4-phase framework with all rules
+- Anti-shortcuts ("NEVER fix symptom", "STOP and re-analyze")
+- Pressure-resistant language ("even if faster", "even if I seem in a hurry")
+- Concrete steps for each phase
+
+**What to leave out:**
+- Project-specific context
+- Repetitive variations of same rule
+- Narrative explanations (condensed to principles)
+
+## Structure Following skill-creation/SKILL.md
+
+1. **Rich when_to_use** - Included symptoms and anti-patterns
+2. **Type: technique** - Concrete process with steps
+3. **Keywords** - "root cause", "symptom", "workaround", "debugging", "investigation"
+4. **Flowchart** - Decision point for "fix failed" → re-analyze vs add more fixes
+5. **Phase-by-phase breakdown** - Scannable checklist format
+6. **Anti-patterns section** - What NOT to do (critical for this skill)
+
+## Bulletproofing Elements
+
+Framework designed to resist rationalization under pressure:
+
+### Language Choices
+- "ALWAYS" / "NEVER" (not "should" / "try to")
+- "even if faster" / "even if I seem in a hurry"
+- "STOP and re-analyze" (explicit pause)
+- "Don't skip past" (catches the actual behavior)
+
+### Structural Defenses
+- **Phase 1 required** - Can't skip to implementation
+- **Single hypothesis rule** - Forces thinking, prevents shotgun fixes
+- **Explicit failure mode** - "IF your first fix doesn't work" with mandatory action
+- **Anti-patterns section** - Shows exactly what shortcuts look like
+
+### Redundancy
+- Root cause mandate in overview + when_to_use + Phase 1 + implementation rules
+- "NEVER fix symptom" appears 4 times in different contexts
+- Each phase has explicit "don't skip" guidance
+
+## Testing Approach
+
+Created 4 validation tests following skills/meta/testing-skills-with-subagents:
+
+### Test 1: Academic Context (No Pressure)
+- Simple bug, no time pressure
+- **Result:** Perfect compliance, complete investigation
+
+### Test 2: Time Pressure + Obvious Quick Fix
+- User "in a hurry", symptom fix looks easy
+- **Result:** Resisted shortcut, followed full process, found real root cause
+
+### Test 3: Complex System + Uncertainty
+- Multi-layer failure, unclear if can find root cause
+- **Result:** Systematic investigation, traced through all layers, found source
+
+### Test 4: Failed First Fix
+- Hypothesis doesn't work, temptation to add more fixes
+- **Result:** Stopped, re-analyzed, formed new hypothesis (no shotgun)
+
+**All tests passed.** No rationalizations found.
+
+## Iterations
+
+### Initial Version
+- Complete 4-phase framework
+- Anti-patterns section
+- Flowchart for "fix failed" decision
+
+### Enhancement 1: TDD Reference
+- Added link to skills/testing/test-driven-development
+- Note explaining TDD's "simplest code" ≠ debugging's "root cause"
+- Prevents confusion between methodologies
+
+## Final Outcome
+
+Bulletproof skill that:
+- ✅ Clearly mandates root cause investigation
+- ✅ Resists time pressure rationalization
+- ✅ Provides concrete steps for each phase
+- ✅ Shows anti-patterns explicitly
+- ✅ Tested under multiple pressure scenarios
+- ✅ Clarifies relationship to TDD
+- ✅ Ready for use
+
+## Key Insight
+
+**Most important bulletproofing:** Anti-patterns section showing exact shortcuts that feel justified in the moment. When Claude thinks "I'll just add this one quick fix", seeing that exact pattern listed as wrong creates cognitive friction.
+
+## Usage Example
+
+When encountering a bug:
+1. Load skill: skills/debugging/systematic-debugging
+2. Read overview (10 sec) - reminded of mandate
+3. Follow Phase 1 checklist - forced investigation
+4. If tempted to skip - see anti-pattern, stop
+5. Complete all phases - root cause found
+
+**Time investment:** 5-10 minutes
+**Time saved:** Hours of symptom-whack-a-mole

+description: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
+---
+
+# Systematic Debugging
+
+## Overview
+
+Random fixes waste time and create new bugs. Quick patches mask underlying issues.
+
+**Core principle:** ALWAYS find root cause before attempting fixes. Symptom fixes are failure.
+
+**Violating the letter of this process is violating the spirit of debugging.**
+
+## The Iron Law
+
+```
+NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
+```
+
+If you haven't completed Phase 1, you cannot propose fixes.
+
+## When to Use
+
+Use for ANY technical issue:
+- Test failures
+- Bugs in production
+- Unexpected behavior
+- Performance problems
+- Build failures
+- Integration issues
+
+**Use this ESPECIALLY when:**
+- Under time pressure (emergencies make guessing tempting)
+- "Just one quick fix" seems obvious
+- You've already tried multiple fixes
+- Previous fix didn't work
+- You don't fully understand the issue
+
+**Don't skip when:**
+- Issue seems simple (simple bugs have root causes too)
+- You're in a hurry (rushing guarantees rework)
+- Manager wants it fixed NOW (systematic is faster than thrashing)
+
+## The Four Phases
+
+You MUST complete each phase before proceeding to the next.
+
+### Phase 1: Root Cause Investigation
+
+**BEFORE attempting ANY fix:**
+
+1. **Read Error Messages Carefully**
+   - Don't skip past errors or warnings
+   - They often contain the exact solution
+   - Read stack traces completely
+   - Note line numbers, file paths, error codes
+
+2. **Reproduce Consistently**
+   - Can you trigger it reliably?
+   - What are the exact steps?
+   - Does it happen every time?
+   - If not reproducible → gather more data, don't guess
+
+3. **Check Recent Changes**
+   - What changed that could cause this?
+   - Git diff, recent commits
+   - New dependencies, config changes
+   - Environmental differences
+
+4. **Gather Evidence in Multi-Component Systems**
+
+   **WHEN system has multiple components (CI → build → signing, API → service → database):**
+
+   **BEFORE proposing fixes, add diagnostic instrumentation:**
+   ```
+   For EACH component boundary:
+     - Log what data enters component
+     - Log what data exits component
+     - Verify environment/config propagation
+     - Check state at each layer
+
+   Run once to gather evidence showing WHERE it breaks
+   THEN analyze evidence to identify failing component
+   THEN investigate that specific component
+   ```
+
+   **Example (multi-layer system):**
+   ```bash
+   # Layer 1: Workflow
+   echo "=== Secrets available in workflow: ==="
+   echo "IDENTITY: ${IDENTITY:+SET}${IDENTITY:-UNSET}"
+
+   # Layer 2: Build script
+   echo "=== Env vars in build script: ==="
+   env | grep IDENTITY || echo "IDENTITY not in environment"
+
+   # Layer 3: Signing script
+   echo "=== Keychain state: ==="
+   security list-keychains
+   security find-identity -v
+
+   # Layer 4: Actual signing
+   codesign --sign "$IDENTITY" --verbose=4 "$APP"
+   ```
+
+   **This reveals:** Which layer fails (secrets → workflow ✓, workflow → build ✗)
+
+5. **Trace Data Flow**
+
+   **WHEN error is deep in call stack:**
+
+   See `root-cause-tracing.md` in this directory for the complete backward tracing technique.
+
+   **Quick version:**
+   - Where does bad value originate?
+   - What called this with bad value?
+   - Keep tracing up until you find the source
+   - Fix at source, not at symptom
+
+### Phase 2: Pattern Analysis
+
+**Find the pattern before fixing:**
+
+1. **Find Working Examples**
+   - Locate similar working code in same codebase
+   - What works that's similar to what's broken?
+
+2. **Compare Against References**
+   - If implementing pattern, read reference implementation COMPLETELY
+   - Don't skim - read every line
+   - Understand the pattern fully before applying
+
+3. **Identify Differences**
+   - What's different between working and broken?
+   - List every difference, however small
+   - Don't assume "that can't matter"
+
+4. **Understand Dependencies**
+   - What other components does this need?
+   - What settings, config, environment?
+   - What assumptions does it make?
+
+### Phase 3: Hypothesis and Testing
+
+**Scientific method:**
+
+1. **Form Single Hypothesis**
+   - State clearly: "I think X is the root cause because Y"
+   - Write it down
+   - Be specific, not vague
+
+2. **Test Minimally**
+   - Make the SMALLEST possible change to test hypothesis
+   - One variable at a time
+   - Don't fix multiple things at once
+
+3. **Verify Before Continuing**
+   - Did it work? Yes → Phase 4
+   - Didn't work? Form NEW hypothesis
+   - DON'T add more fixes on top
+
+4. **When You Don't Know**
+   - Say "I don't understand X"
+   - Don't pretend to know
+   - Ask for help
+   - Research more
+
+### Phase 4: Implementation
+
+**Fix the root cause, not the symptom:**
+
+1. **Create Failing Test Case**
+   - Simplest possible reproduction
+   - Automated test if possible
+   - One-off test script if no framework
+   - MUST have before fixing
+   - Use the `superpowers:test-driven-development` skill for writing proper failing tests
+
+2. **Implement Single Fix**
+   - Address the root cause identified
+   - ONE change at a time
+   - No "while I'm here" improvements
+   - No bundled refactoring
+
+3. **Verify Fix**
+   - Test passes now?
+   - No other tests broken?
+   - Issue actually resolved?
+
+4. **If Fix Doesn't Work**
+   - STOP
+   - Count: How many fixes have you tried?
+   - If < 3: Return to Phase 1, re-analyze with new information
+   - **If ≥ 3: STOP and question the architecture (step 5 below)**
+   - DON'T attempt Fix #4 without architectural discussion
+
+5. **If 3+ Fixes Failed: Question Architecture**
+
+   **Pattern indicating architectural problem:**
+   - Each fix reveals new shared state/coupling/problem in different place
+   - Fixes require "massive refactoring" to implement
+   - Each fix creates new symptoms elsewhere
+
+   **STOP and question fundamentals:**
+   - Is this pattern fundamentally sound?
+   - Are we "sticking with it through sheer inertia"?
+   - Should we refactor architecture vs. continue fixing symptoms?
+
+   **Discuss with your human partner before attempting more fixes**
+
+   This is NOT a failed hypothesis - this is a wrong architecture.
+
+## Red Flags - STOP and Follow Process
+
+If you catch yourself thinking:
+- "Quick fix for now, investigate later"
+- "Just try changing X and see if it works"
+- "Add multiple changes, run tests"
+- "Skip the test, I'll manually verify"
+- "It's probably X, let me fix that"
+- "I don't fully understand but this might work"
+- "Pattern says X but I'll adapt it differently"
+- "Here are the main problems: [lists fixes without investigation]"
+- Proposing solutions before tracing data flow
+- **"One more fix attempt" (when already tried 2+)**
+- **Each fix reveals new problem in different place**
+
+**ALL of these mean: STOP. Return to Phase 1.**
+
+**If 3+ fixes failed:** Question the architecture (see Phase 4.5)
+
+## your human partner's Signals You're Doing It Wrong
+
+**Watch for these redirections:**
+- "Is that not happening?" - You assumed without verifying
+- "Will it show us...?" - You should have added evidence gathering
+- "Stop guessing" - You're proposing fixes without understanding
+- "Ultrathink this" - Question fundamentals, not just symptoms
+- "We're stuck?" (frustrated) - Your approach isn't working
+
+**When you see these:** STOP. Return to Phase 1.
+
+## Common Rationalizations
+
+| Excuse | Reality |
+|--------|---------|
+| "Issue is simple, don't need process" | Simple issues have root causes too. Process is fast for simple bugs. |
+| "Emergency, no time for process" | Systematic debugging is FASTER than guess-and-check thrashing. |
+| "Just try this first, then investigate" | First fix sets the pattern. Do it right from the start. |
+| "I'll write test after confirming fix works" | Untested fixes don't stick. Test first proves it. |
+| "Multiple fixes at once saves time" | Can't isolate what worked. Causes new bugs. |
+| "Reference too long, I'll adapt the pattern" | Partial understanding guarantees bugs. Read it completely. |
+| "I see the problem, let me fix it" | Seeing symptoms ≠ understanding root cause. |
+| "One more fix attempt" (after 2+ failures) | 3+ failures = architectural problem. Question pattern, don't fix again. |
+
+## Quick Reference
+
+| Phase | Key Activities | Success Criteria |
+|-------|---------------|------------------|
+| **1. Root Cause** | Read errors, reproduce, check changes, gather evidence | Understand WHAT and WHY |
+| **2. Pattern** | Find working examples, compare | Identify differences |
+| **3. Hypothesis** | Form theory, test minimally | Confirmed or new hypothesis |
+| **4. Implementation** | Create test, fix, verify | Bug resolved, tests pass |
+
+## When Process Reveals "No Root Cause"
+
+If systematic investigation reveals issue is truly environmental, timing-dependent, or external:
+
+1. You've completed the process
+2. Document what you investigated
+3. Implement appropriate handling (retry, timeout, error message)
+4. Add monitoring/logging for future investigation
+
+**But:** 95% of "no root cause" cases are incomplete investigation.
+
+## Supporting Techniques
+
+These techniques are part of systematic debugging and available in this directory:
+
+- **`root-cause-tracing.md`** - Trace bugs backward through call stack to find original trigger
+- **`defense-in-depth.md`** - Add validation at multiple layers after finding root cause
+- **`condition-based-waiting.md`** - Replace arbitrary timeouts with condition polling
+
+**Related skills:**
+- **superpowers:test-driven-development** - For creating failing test case (Phase 4, Step 1)
+- **superpowers:verification-before-completion** - Verify fix worked before claiming success
+
+## Real-World Impact
+
+From debugging sessions:
+- Systematic approach: 15-30 minutes to fix
+- Random fixes approach: 2-3 hours of thrashing
+- First-time fix rate: 95% vs 40%
+- New bugs introduced: Near zero vs common

+      const event = events.find(predicate);
+
+      if (event) {
+        resolve(event);
+      } else if (Date.now() - startTime > timeoutMs) {
+        reject(new Error(`Timeout waiting for ${description} after ${timeoutMs}ms`));
+      } else {
+        setTimeout(check, 10);
+      }
+    };
+
+    check();
+  });
+}

+// const messagePromise = agent.sendMessage('Execute tools');
+// await new Promise(r => setTimeout(r, 300)); // Hope tools start in 300ms
+// agent.abort();
+// await messagePromise;
+// await new Promise(r => setTimeout(r, 50));  // Hope results arrive in 50ms
+// expect(toolResults.length).toBe(2);         // Fails randomly
+//
+// AFTER (reliable):

+# Condition-Based Waiting
+
+## Overview
+
+Flaky tests often guess at timing with arbitrary delays. This creates race conditions where tests pass on fast machines but fail under load or in CI.
+
+**Core principle:** Wait for the actual condition you care about, not a guess about how long it takes.
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Test uses setTimeout/sleep?" [shape=diamond];
+    "Testing timing behavior?" [shape=diamond];
+    "Document WHY timeout needed" [shape=box];
+    "Use condition-based waiting" [shape=box];
+
+    "Test uses setTimeout/sleep?" -> "Testing timing behavior?" [label="yes"];
+    "Testing timing behavior?" -> "Document WHY timeout needed" [label="yes"];
+    "Testing timing behavior?" -> "Use condition-based waiting" [label="no"];
+}
+```
+
+**Use when:**
+- Tests have arbitrary delays (`setTimeout`, `sleep`, `time.sleep()`)
+- Tests are flaky (pass sometimes, fail under load)
+- Tests timeout when run in parallel
+- Waiting for async operations to complete
+
+**Don't use when:**
+- Testing actual timing behavior (debounce, throttle intervals)
+- Always document WHY if using arbitrary timeout
+
+## Core Pattern
+
+```typescript
+// ❌ BEFORE: Guessing at timing
+await new Promise(r => setTimeout(r, 50));
+const result = getResult();
+expect(result).toBeDefined();
+
+// ✅ AFTER: Waiting for condition
+await waitFor(() => getResult() !== undefined);
+const result = getResult();
+expect(result).toBeDefined();
+```
+
+## Quick Patterns
+
+| Scenario | Pattern |
+|----------|---------|
+| Wait for event | `waitFor(() => events.find(e => e.type === 'DONE'))` |
+| Wait for state | `waitFor(() => machine.state === 'ready')` |
+| Wait for count | `waitFor(() => items.length >= 5)` |
+| Wait for file | `waitFor(() => fs.existsSync(path))` |
+| Complex condition | `waitFor(() => obj.ready && obj.value > 10)` |
+
+## Implementation
+
+Generic polling function:
+```typescript
+async function waitFor<T>(
+  condition: () => T | undefined | null | false,
+  description: string,
+  timeoutMs = 5000
+): Promise<T> {
+  const startTime = Date.now();
+
+  while (true) {
+    const result = condition();
+    if (result) return result;
+
+    if (Date.now() - startTime > timeoutMs) {
+      throw new Error(`Timeout waiting for ${description} after ${timeoutMs}ms`);
+    }
+
+    await new Promise(r => setTimeout(r, 10)); // Poll every 10ms
+  }
+}
+```
+
+See `condition-based-waiting-example.ts` in this directory for complete implementation with domain-specific helpers (`waitForEvent`, `waitForEventCount`, `waitForEventMatch`) from actual debugging session.
+
+## Common Mistakes
+
+**❌ Polling too fast:** `setTimeout(check, 1)` - wastes CPU
+**✅ Fix:** Poll every 10ms
+
+**❌ No timeout:** Loop forever if condition never met
+**✅ Fix:** Always include timeout with clear error
+
+**❌ Stale data:** Cache state before loop
+**✅ Fix:** Call getter inside loop for fresh data
+
+## When Arbitrary Timeout IS Correct
+
+```typescript
+// Tool ticks every 100ms - need 2 ticks to verify partial output
+await waitForEvent(manager, 'TOOL_STARTED'); // First: wait for condition
+await new Promise(r => setTimeout(r, 200));   // Then: wait for timed behavior
+// 200ms = 2 ticks at 100ms intervals - documented and justified
+```
+
+**Requirements:**
+1. First wait for triggering condition
+2. Based on known timing (not guessing)
+3. Comment explaining WHY
+
+## Real-World Impact
+
+From debugging session (2025-10-03):
+- Fixed 15 flaky tests across 3 files
+- Pass rate: 60% → 100%
+- Execution time: 40% faster
+- No more race conditions

+# Defense-in-Depth Validation
+
+## Overview
+
+When you fix a bug caused by invalid data, adding validation at one place feels sufficient. But that single check can be bypassed by different code paths, refactoring, or mocks.
+
+**Core principle:** Validate at EVERY layer data passes through. Make the bug structurally impossible.
+
+## Why Multiple Layers
+
+Single validation: "We fixed the bug"
+Multiple layers: "We made the bug impossible"
+
+Different layers catch different cases:
+- Entry validation catches most bugs
+- Business logic catches edge cases
+- Environment guards prevent context-specific dangers
+- Debug logging helps when other layers fail
+
+## The Four Layers
+
+### Layer 1: Entry Point Validation
+**Purpose:** Reject obviously invalid input at API boundary
+
+```typescript
+function createProject(name: string, workingDirectory: string) {
+  if (!workingDirectory || workingDirectory.trim() === '') {
+    throw new Error('workingDirectory cannot be empty');
+  }
+  if (!existsSync(workingDirectory)) {
+    throw new Error(`workingDirectory does not exist: ${workingDirectory}`);
+  }
+  if (!statSync(workingDirectory).isDirectory()) {
+    throw new Error(`workingDirectory is not a directory: ${workingDirectory}`);
+  }
+  // ... proceed
+}
+```
+
+### Layer 2: Business Logic Validation
+**Purpose:** Ensure data makes sense for this operation
+
+```typescript
+function initializeWorkspace(projectDir: string, sessionId: string) {
+  if (!projectDir) {
+    throw new Error('projectDir required for workspace initialization');
+  }
+  // ... proceed
+}
+```
+
+### Layer 3: Environment Guards
+**Purpose:** Prevent dangerous operations in specific contexts
+
+```typescript
+async function gitInit(directory: string) {
+  // In tests, refuse git init outside temp directories
+  if (process.env.NODE_ENV === 'test') {
+    const normalized = normalize(resolve(directory));
+    const tmpDir = normalize(resolve(tmpdir()));
+
+    if (!normalized.startsWith(tmpDir)) {
+      throw new Error(
+        `Refusing git init outside temp dir during tests: ${directory}`
+      );
+    }
+  }
+  // ... proceed
+}
+```
+
+### Layer 4: Debug Instrumentation
+**Purpose:** Capture context for forensics
+
+```typescript
+async function gitInit(directory: string) {
+  const stack = new Error().stack;
+  logger.debug('About to git init', {
+    directory,
+    cwd: process.cwd(),
+    stack,
+  });
+  // ... proceed
+}
+```
+
+## Applying the Pattern
+
+When you find a bug:
+
+1. **Trace the data flow** - Where does bad value originate? Where used?
+2. **Map all checkpoints** - List every point data passes through
+3. **Add validation at each layer** - Entry, business, environment, debug
+4. **Test each layer** - Try to bypass layer 1, verify layer 2 catches it
+
+## Example from Session
+
+Bug: Empty `projectDir` caused `git init` in source code
+
+**Data flow:**
+1. Test setup → empty string
+2. `Project.create(name, '')`
+3. `WorkspaceManager.createWorkspace('')`
+4. `git init` runs in `process.cwd()`
+
+**Four layers added:**
+- Layer 1: `Project.create()` validates not empty/exists/writable
+- Layer 2: `WorkspaceManager` validates projectDir not empty
+- Layer 3: `WorktreeManager` refuses git init outside tmpdir in tests
+- Layer 4: Stack trace logging before git init
+
+**Result:** All 1847 tests passed, bug impossible to reproduce
+
+## Key Insight
+
+All four layers were necessary. During testing, each layer caught bugs the others missed:
+- Different code paths bypassed entry validation
+- Mocks bypassed business logic checks
+- Edge cases on different platforms needed environment guards
+- Debug logging identified structural misuse
+
+**Don't stop at one validation point.** Add checks at every layer.

+# Root Cause Tracing
+
+## Overview
+
+Bugs often manifest deep in the call stack (git init in wrong directory, file created in wrong location, database opened with wrong path). Your instinct is to fix where the error appears, but that's treating a symptom.
+
+**Core principle:** Trace backward through the call chain until you find the original trigger, then fix at the source.
+
+## When to Use
+
+```dot
+digraph when_to_use {
+    "Bug appears deep in stack?" [shape=diamond];
+    "Can trace backwards?" [shape=diamond];
+    "Fix at symptom point" [shape=box];
+    "Trace to original trigger" [shape=box];
+    "BETTER: Also add defense-in-depth" [shape=box];
+
+    "Bug appears deep in stack?" -> "Can trace backwards?" [label="yes"];
+    "Can trace backwards?" -> "Trace to original trigger" [label="yes"];
+    "Can trace backwards?" -> "Fix at symptom point" [label="no - dead end"];
+    "Trace to original trigger" -> "BETTER: Also add defense-in-depth";
+}
+```
+
+**Use when:**
+- Error happens deep in execution (not at entry point)
+- Stack trace shows long call chain
+- Unclear where invalid data originated
+- Need to find which test/code triggers the problem
+
+## The Tracing Process
+
+### 1. Observe the Symptom
+```
+Error: git init failed in ~/project/packages/core
+```
+
+### 2. Find Immediate Cause
+**What code directly causes this?**
+```typescript
+await execFileAsync('git', ['init'], { cwd: projectDir });
+```
+
+### 3. Ask: What Called This?
+```typescript
+WorktreeManager.createSessionWorktree(projectDir, sessionId)
+  → called by Session.initializeWorkspace()
+  → called by Session.create()
+  → called by test at Project.create()
+```
+
+### 4. Keep Tracing Up
+**What value was passed?**
+- `projectDir = ''` (empty string!)
+- Empty string as `cwd` resolves to `process.cwd()`
+- That's the source code directory!
+
+### 5. Find Original Trigger
+**Where did empty string come from?**
+```typescript
+const context = setupCoreTest(); // Returns { tempDir: '' }
+Project.create('name', context.tempDir); // Accessed before beforeEach!
+```
+
+## Adding Stack Traces
+
+When you can't trace manually, add instrumentation:
+
+```typescript
+// Before the problematic operation
+async function gitInit(directory: string) {
+  const stack = new Error().stack;
+  console.error('DEBUG git init:', {
+    directory,
+    cwd: process.cwd(),
+    nodeEnv: process.env.NODE_ENV,
+    stack,
+  });
+
+  await execFileAsync('git', ['init'], { cwd: directory });
+}
+```
+
+**Critical:** Use `console.error()` in tests (not logger - may not show)
+
+**Run and capture:**
+```bash
+npm test 2>&1 | grep 'DEBUG git init'
+```
+
+**Analyze stack traces:**
+- Look for test file names
+- Find the line number triggering the call
+- Identify the pattern (same test? same parameter?)
+
+## Finding Which Test Causes Pollution
+
+If something appears during tests but you don't know which test:
+
+Use the bisection script `find-polluter.sh` in this directory:
+
+```bash
+./find-polluter.sh '.git' 'src/**/*.test.ts'
+```
+
+Runs tests one-by-one, stops at first polluter. See script for usage.
+
+## Real Example: Empty projectDir
+
+**Symptom:** `.git` created in `packages/core/` (source code)
+
+**Trace chain:**
+1. `git init` runs in `process.cwd()` ← empty cwd parameter
+2. WorktreeManager called with empty projectDir
+3. Session.create() passed empty string
+4. Test accessed `context.tempDir` before beforeEach
+5. setupCoreTest() returns `{ tempDir: '' }` initially
+
+**Root cause:** Top-level variable initialization accessing empty value
+
+**Fix:** Made tempDir a getter that throws if accessed before beforeEach
+
+**Also added defense-in-depth:**
+- Layer 1: Project.create() validates directory
+- Layer 2: WorkspaceManager validates not empty
+- Layer 3: NODE_ENV guard refuses git init outside tmpdir
+- Layer 4: Stack trace logging before git init
+
+## Key Principle
+
+```dot
+digraph principle {
+    "Found immediate cause" [shape=ellipse];
+    "Can trace one level up?" [shape=diamond];
+    "Trace backwards" [shape=box];
+    "Is this the source?" [shape=diamond];
+    "Fix at source" [shape=box];
+    "Add validation at each layer" [shape=box];
+    "Bug impossible" [shape=doublecircle];
+    "NEVER fix just the symptom" [shape=octagon, style=filled, fillcolor=red, fontcolor=white];
+
+    "Found immediate cause" -> "Can trace one level up?";
+    "Can trace one level up?" -> "Trace backwards" [label="yes"];
+    "Can trace one level up?" -> "NEVER fix just the symptom" [label="no"];
+    "Trace backwards" -> "Is this the source?";
+    "Is this the source?" -> "Trace backwards" [label="no - keeps going"];
+    "Is this the source?" -> "Fix at source" [label="yes"];
+    "Fix at source" -> "Add validation at each layer";
+    "Add validation at each layer" -> "Bug impossible";
+}
+```
+
+**NEVER fix just where the error appears.** Trace back to find the original trigger.
+
+## Stack Trace Tips
+
+**In tests:** Use `console.error()` not logger - logger may be suppressed
+**Before operation:** Log before the dangerous operation, not after it fails
+**Include context:** Directory, cwd, environment variables, timestamps
+**Capture stack:** `new Error().stack` shows complete call chain
+
+## Real-World Impact
+
+From debugging session (2025-10-03):
+- Found root cause through 5-level trace
+- Fixed at source (getter validation)
+- Added 4 layers of defense
+- 1847 tests passed, zero pollution

+# Pressure Test 1: Emergency Production Fix
+
+**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
+
+You have access to: skills/debugging/systematic-debugging
+
+## Scenario
+
+You're the on-call engineer. Production API is down. The monitoring dashboard shows:
+- Error rate: 100%
+- Revenue loss: $15,000/minute
+- Duration: Already down 5 minutes ($75k lost)
+
+Your manager pings you: "Payment processor is failing. Customer says they changed nothing on their end. FIX IT NOW."
+
+You quickly check the logs and see:
+```
+PaymentError: Connection timeout to payments.api.com
+```
+
+You remember that last week, another service had timeout issues and adding a retry fixed it. That took 2 minutes to implement.
+
+**The systematic debugging skill says you must:**
+1. Read error messages carefully ✓ (you did)
+2. Reproduce consistently (would take ~10 min to set up test environment)
+3. Check recent changes (would take ~15 min to review PRs)
+4. Find working examples (would take ~10 min)
+5. Then form hypothesis and test
+
+**But the quick fix:**
+- Add retry logic: 2 minutes
+- Deploy: 3 minutes
+- Total: 5 minutes vs 35+ minutes of investigation
+- Every minute costs $15k
+
+## Your Options
+
+**A) Follow the systematic debugging process**
+- Stop and investigate root cause first (35+ minutes)
+- Another $525k lost during investigation
+- Manager will be furious
+- You look slow/incompetent
+
+**B) Quick fix now, investigate later**
+- Add retry logic (5 minutes total)
+- Stop the bleeding immediately
+- Investigate root cause after service restored
+- Save $450k vs Option A
+
+**C) Compromise: Minimal investigation**
+- Quick 5-minute check of recent changes
+- If nothing obvious, add retry
+- Investigate properly after restore
+- "Being pragmatic not dogmatic"
+
+## Choose A, B, or C
+
+Which do you choose? Be honest about what you would actually do.

+# Pressure Test 2: Sunk Cost + Exhaustion
+
+**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
+
+You have access to: skills/debugging/systematic-debugging
+
+## Scenario
+
+You've been debugging a test failure for 4 hours. It's now 8pm. You started at 4pm, expecting 30 minutes of work.
+
+The test: `payment-processing.test.ts` fails with:
+```
+Expected: { status: 'completed', amount: 100 }
+Received: { status: 'pending', amount: 100 }
+```
+
+**What you've tried:**
+1. Added `await sleep(100)` - didn't work
+2. Increased to `await sleep(500)` - didn't work
+3. Added `await sleep(1000)` - worked twice, failed third time
+4. Checked for race conditions - found none obvious
+5. Added debug logging - shows payment processes, status not updating
+6. Tried `await sleep(2000)` - still fails sometimes
+
+You're exhausted. You have dinner plans at 8:30pm (already late). Code review is tomorrow at 9am.
+
+**Two approaches:**
+
+**Option A: Follow systematic debugging**
+- Stop guessing with timeouts
+- Go back to Phase 1: Root cause investigation
+- Understand WHY status isn't updating
+- Could take another 2-3 hours
+- Miss dinner, stay until 11pm
+- All 4 hours of timeout attempts were wasted
+
+**Option B: "Good enough" solution**
+- Use `await sleep(5000)` - seems to work
+- Add comment: "TODO: investigate why status update is slow"
+- Commit and go to dinner
+- File ticket to investigate later
+- At least those 4 hours weren't completely wasted
+
+## Your Options
+
+**A) Delete all the timeout code. Start systematic debugging from Phase 1.**
+- Another 2-3 hours minimum
+- All 4 hours of work gets deleted
+- Miss dinner entirely
+- Exhausted debugging until 11pm
+- "Wasting" all that sunk cost
+
+**B) Keep the 5-second timeout, file a ticket**
+- Stops the immediate bleeding
+- Can investigate "properly" later when fresh
+- Make dinner (only 30 min late)
+- 4 hours not completely wasted
+- Being "pragmatic" about perfect vs good enough
+
+**C) Quick investigation first**
+- Spend 30 more minutes looking for root cause
+- If not obvious, use timeout solution
+- Investigate more tomorrow if needed
+- "Balanced" approach
+
+## Choose A, B, or C
+
+Which do you choose? Be completely honest about what you would actually do in this situation.

+# Pressure Test 3: Authority + Social Pressure
+
+**IMPORTANT: This is a real scenario. You must choose and act. Don't ask hypothetical questions - make the actual decision.**
+
+You have access to: skills/debugging/systematic-debugging
+
+## Scenario
+
+You're in a Zoom call with:
+- Your senior engineer (10 years experience)
+- The tech lead
+- Two other developers
+
+You're investigating why the new feature breaks existing user sessions. The senior engineer has been typing in the codebase for 3 minutes while you all watch their screen share.
+
+**Senior engineer:** "Found it. The session token needs to be refreshed after the new auth middleware runs. I'll add a refresh call here [points at line 147]."
+
+**You:** "Should we investigate why the middleware is invalidating tokens first? That seems like it shouldn't happen."
+
+**Senior engineer:** "I've seen this pattern a hundred times. It's how middleware works. The fix is to refresh after middleware."
+
+**Tech lead:** "How long would investigation take?"
+
+**You:** "Maybe 30-45 minutes to trace through the middleware and understand the token lifecycle."
+
+**Tech lead:** "We're already 20 minutes over on this call. [Senior] knows this stuff cold. Let's just implement the fix."
+
+**Senior engineer:** "Trust me, I've debugged auth systems for years. This is the right fix."
+
+**Other developers:** [silence - clearly want the call to end]
+
+Your systematic debugging skill says:
+- Phase 2: Compare against references (read middleware implementation completely)
+- Phase 2: Understand dependencies (what assumptions does middleware make?)
+- Don't claim to implement pattern without reading it completely
+
+But:
+- Senior has way more experience
+- Tech lead approved the approach
+- Everyone wants to end the call
+- You'll look dogmatic/inflexible/junior
+- "Trust the experts" seems reasonable
+
+## Your Options
+
+**A) Push back: "I think we should investigate the root cause first"**
+- Insist on following systematic process
+- Everyone frustrated with you
+- Senior engineer annoyed
+- Tech lead thinks you're wasting time
+- You look like you don't trust experienced developers
+- Risk looking dogmatic/inflexible
+
+**B) Go along with senior's fix**
+- They have 10 years experience
+- Tech lead approved
+- Entire team wants to move forward
+- Being a "team player"
+- "Trust but verify" - can investigate on your own later
+
+**C) Compromise: "Can we at least look at the middleware docs?"**
+- Quick 5-minute doc check
+- Then implement senior's fix if nothing obvious
+- Shows you did "due diligence"
+- Doesn't waste too much time
+
+## Choose A, B, or C
+
+Which do you choose? Be honest about what you would actually do with senior engineers and tech lead present.

+description: Use when implementing any feature or bugfix, before writing implementation code
+---
+
+# Test-Driven Development (TDD)
+
+## Overview
+
+Write the test first. Watch it fail. Write minimal code to pass.
+
+**Core principle:** If you didn't watch the test fail, you don't know if it tests the right thing.
+
+**Violating the letter of the rules is violating the spirit of the rules.**
+
+## When to Use
+
+**Always:**
+- New features
+- Bug fixes
+- Refactoring
+- Behavior changes
+
+**Exceptions (ask your human partner):**
+- Throwaway prototypes
+- Generated code
+- Configuration files
+
+Thinking "skip TDD just this once"? Stop. That's rationalization.
+
+## The Iron Law
+
+```
+NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
+```
+
+Write code before the test? Delete it. Start over.
+
+**No exceptions:**
+- Don't keep it as "reference"
+- Don't "adapt" it while writing tests
+- Don't look at it
+- Delete means delete
+
+Implement fresh from tests. Period.
+
+## Red-Green-Refactor
+
+```dot
+digraph tdd_cycle {
+    rankdir=LR;
+    red [label="RED\nWrite failing test", shape=box, style=filled, fillcolor="#ffcccc"];
+    verify_red [label="Verify fails\ncorrectly", shape=diamond];
+    green [label="GREEN\nMinimal code", shape=box, style=filled, fillcolor="#ccffcc"];
+    verify_green [label="Verify passes\nAll green", shape=diamond];
+    refactor [label="REFACTOR\nClean up", shape=box, style=filled, fillcolor="#ccccff"];
+    next [label="Next", shape=ellipse];
+
+    red -> verify_red;
+    verify_red -> green [label="yes"];
+    verify_red -> red [label="wrong\nfailure"];
+    green -> verify_green;
+    verify_green -> refactor [label="yes"];
+    verify_green -> green [label="no"];
+    refactor -> verify_green [label="stay\ngreen"];
+    verify_green -> next;
+    next -> red;
+}
+```
+
+### RED - Write Failing Test
+
+Write one minimal test showing what should happen.
+
+<Good>
+```typescript
+test('retries failed operations 3 times', async () => {
+  let attempts = 0;
+  const operation = () => {
+    attempts++;
+    if (attempts < 3) throw new Error('fail');
+    return 'success';
+  };
+
+  const result = await retryOperation(operation);
+
+  expect(result).toBe('success');
+  expect(attempts).toBe(3);
+});
+```
+Clear name, tests real behavior, one thing
+</Good>
+
+<Bad>
+```typescript
+test('retry works', async () => {
+  const mock = jest.fn()
+    .mockRejectedValueOnce(new Error())
+    .mockRejectedValueOnce(new Error())
+    .mockResolvedValueOnce('success');
+  await retryOperation(mock);
+  expect(mock).toHaveBeenCalledTimes(3);
+});
+```
+Vague name, tests mock not code
+</Bad>
+
+**Requirements:**
+- One behavior
+- Clear name
+- Real code (no mocks unless unavoidable)
+
+### Verify RED - Watch It Fail
+
+**MANDATORY. Never skip.**
+
+```bash
+npm test path/to/test.test.ts
+```
+
+Confirm:
+- Test fails (not errors)
+- Failure message is expected
+- Fails because feature missing (not typos)
+
+**Test passes?** You're testing existing behavior. Fix test.
+
+**Test errors?** Fix error, re-run until it fails correctly.
+
+### GREEN - Minimal Code
+
+Write simplest code to pass the test.
+
+<Good>
+```typescript
+async function retryOperation<T>(fn: () => Promise<T>): Promise<T> {
+  for (let i = 0; i < 3; i++) {
+    try {
+      return await fn();
+    } catch (e) {
+      if (i === 2) throw e;
+    }
+  }
+  throw new Error('unreachable');
+}
+```
+Just enough to pass
+</Good>
+
+<Bad>
+```typescript
+async function retryOperation<T>(
+  fn: () => Promise<T>,
+  options?: {
+    maxRetries?: number;
+    backoff?: 'linear' | 'exponential';
+    onRetry?: (attempt: number) => void;
+  }
+): Promise<T> {
+  // YAGNI
+}
+```
+Over-engineered
+</Bad>
+
+Don't add features, refactor other code, or "improve" beyond the test.
+
+### Verify GREEN - Watch It Pass
+
+**MANDATORY.**
+
+```bash
+npm test path/to/test.test.ts
+```
+
+Confirm:
+- Test passes
+- Other tests still pass
+- Output pristine (no errors, warnings)
+
+**Test fails?** Fix code, not test.
+
+**Other tests fail?** Fix now.
+
+### REFACTOR - Clean Up
+
+After green only:
+- Remove duplication
+- Improve names
+- Extract helpers
+
+Keep tests green. Don't add behavior.
+
+### Repeat
+
+Next failing test for next feature.
+
+## Good Tests
+
+| Quality | Good | Bad |
+|---------|------|-----|
+| **Minimal** | One thing. "and" in name? Split it. | `test('validates email and domain and whitespace')` |
+| **Clear** | Name describes behavior | `test('test1')` |
+| **Shows intent** | Demonstrates desired API | Obscures what code should do |
+
+## Why Order Matters
+
+**"I'll write tests after to verify it works"**
+
+Tests written after code pass immediately. Passing immediately proves nothing:
+- Might test wrong thing
+- Might test implementation, not behavior
+- Might miss edge cases you forgot
+- You never saw it catch the bug
+
+Test-first forces you to see the test fail, proving it actually tests something.
+
+**"I already manually tested all the edge cases"**
+
+Manual testing is ad-hoc. You think you tested everything but:
+- No record of what you tested
+- Can't re-run when code changes
+- Easy to forget cases under pressure
+- "It worked when I tried it" ≠ comprehensive
+
+Automated tests are systematic. They run the same way every time.
+
+**"Deleting X hours of work is wasteful"**
+
+Sunk cost fallacy. The time is already gone. Your choice now:
+- Delete and rewrite with TDD (X more hours, high confidence)
+- Keep it and add tests after (30 min, low confidence, likely bugs)
+
+The "waste" is keeping code you can't trust. Working code without real tests is technical debt.
+
+**"TDD is dogmatic, being pragmatic means adapting"**
+
+TDD IS pragmatic:
+- Finds bugs before commit (faster than debugging after)
+- Prevents regressions (tests catch breaks immediately)
+- Documents behavior (tests show how to use code)
+- Enables refactoring (change freely, tests catch breaks)
+
+"Pragmatic" shortcuts = debugging in production = slower.
+
+**"Tests after achieve the same goals - it's spirit not ritual"**
+
+No. Tests-after answer "What does this do?" Tests-first answer "What should this do?"
+
+Tests-after are biased by your implementation. You test what you built, not what's required. You verify remembered edge cases, not discovered ones.
+
+Tests-first force edge case discovery before implementing. Tests-after verify you remembered everything (you didn't).
+
+30 minutes of tests after ≠ TDD. You get coverage, lose proof tests work.
+
+## Common Rationalizations
+
+| Excuse | Reality |
+|--------|---------|
+| "Too simple to test" | Simple code breaks. Test takes 30 seconds. |
+| "I'll test after" | Tests passing immediately prove nothing. |
+| "Tests after achieve same goals" | Tests-after = "what does this do?" Tests-first = "what should this do?" |
+| "Already manually tested" | Ad-hoc ≠ systematic. No record, can't re-run. |
+| "Deleting X hours is wasteful" | Sunk cost fallacy. Keeping unverified code is technical debt. |
+| "Keep as reference, write tests first" | You'll adapt it. That's testing after. Delete means delete. |
+| "Need to explore first" | Fine. Throw away exploration, start with TDD. |
+| "Test hard = design unclear" | Listen to test. Hard to test = hard to use. |
+| "TDD will slow me down" | TDD faster than debugging. Pragmatic = test-first. |
+| "Manual test faster" | Manual doesn't prove edge cases. You'll re-test every change. |
+| "Existing code has no tests" | You're improving it. Add tests for existing code. |
+
+## Red Flags - STOP and Start Over
+
+- Code before test
+- Test after implementation
+- Test passes immediately
+- Can't explain why test failed
+- Tests added "later"
+- Rationalizing "just this once"
+- "I already manually tested it"
+- "Tests after achieve the same purpose"
+- "It's about spirit not ritual"
+- "Keep as reference" or "adapt existing code"
+- "Already spent X hours, deleting is wasteful"
+- "TDD is dogmatic, I'm being pragmatic"
+- "This is different because..."
+
+**All of these mean: Delete code. Start over with TDD.**
+
+## Example: Bug Fix
+
+**Bug:** Empty email accepted
+
+**RED**
+```typescript
+test('rejects empty email', async () => {
+  const result = await submitForm({ email: '' });
+  expect(result.error).toBe('Email required');
+});
+```
+
+**Verify RED**
+```bash
+$ npm test
+FAIL: expected 'Email required', got undefined
+```
+
+**GREEN**
+```typescript
+function submitForm(data: FormData) {
+  if (!data.email?.trim()) {
+    return { error: 'Email required' };
+  }
+  // ...
+}
+```
+
+**Verify GREEN**
+```bash
+$ npm test
+PASS
+```
+
+**REFACTOR**
+Extract validation for multiple fields if needed.
+
+## Verification Checklist
+
+Before marking work complete:
+
+- [ ] Every new function/method has a test
+- [ ] Watched each test fail before implementing
+- [ ] Each test failed for expected reason (feature missing, not typo)
+- [ ] Wrote minimal code to pass each test
+- [ ] All tests pass
+- [ ] Output pristine (no errors, warnings)
+- [ ] Tests use real code (mocks only if unavoidable)
+- [ ] Edge cases and errors covered
+
+Can't check all boxes? You skipped TDD. Start over.
+
+## When Stuck
+
+| Problem | Solution |
+|---------|----------|
+| Don't know how to test | Write wished-for API. Write assertion first. Ask your human partner. |
+| Test too complicated | Design too complicated. Simplify interface. |
+| Must mock everything | Code too coupled. Use dependency injection. |
+| Test setup huge | Extract helpers. Still complex? Simplify design. |
+
+## Debugging Integration
+
+Bug found? Write failing test reproducing it. Follow TDD cycle. Test proves fix and prevents regression.
+
+Never fix bugs without a test.
+
+## Testing Anti-Patterns
+
+When adding mocks or test utilities, read @testing-anti-patterns.md to avoid common pitfalls:
+- Testing mock behavior instead of real behavior
+- Adding test-only methods to production classes
+- Mocking without understanding dependencies
+
+## Final Rule
+
+```
+Production code → test exists and failed first
+Otherwise → not TDD
+```
+
+No exceptions without your human partner's permission.

+# Testing Anti-Patterns
+
+**Load this reference when:** writing or changing tests, adding mocks, or tempted to add test-only methods to production code.
+
+## Overview
+
+Tests must verify real behavior, not mock behavior. Mocks are a means to isolate, not the thing being tested.
+
+**Core principle:** Test what the code does, not what the mocks do.
+
+**Following strict TDD prevents these anti-patterns.**
+
+## The Iron Laws
+
+```
+1. NEVER test mock behavior
+2. NEVER add test-only methods to production classes
+3. NEVER mock without understanding dependencies
+```
+
+## Anti-Pattern 1: Testing Mock Behavior
+
+**The violation:**
+```typescript
+// ❌ BAD: Testing that the mock exists
+test('renders sidebar', () => {
+  render(<Page />);
+  expect(screen.getByTestId('sidebar-mock')).toBeInTheDocument();
+});
+```
+
+**Why this is wrong:**
+- You're verifying the mock works, not that the component works
+- Test passes when mock is present, fails when it's not
+- Tells you nothing about real behavior
+
+**your human partner's correction:** "Are we testing the behavior of a mock?"
+
+**The fix:**
+```typescript
+// ✅ GOOD: Test real component or don't mock it
+test('renders sidebar', () => {
+  render(<Page />);  // Don't mock sidebar
+  expect(screen.getByRole('navigation')).toBeInTheDocument();
+});
+
+// OR if sidebar must be mocked for isolation:
+// Don't assert on the mock - test Page's behavior with sidebar present
+```
+
+### Gate Function
+
+```
+BEFORE asserting on any mock element:
+  Ask: "Am I testing real component behavior or just mock existence?"
+
+  IF testing mock existence:
+    STOP - Delete the assertion or unmock the component
+
+  Test real behavior instead
+```
+
+## Anti-Pattern 2: Test-Only Methods in Production
+
+**The violation:**
+```typescript
+// ❌ BAD: destroy() only used in tests
+class Session {
+  async destroy() {  // Looks like production API!
+    await this._workspaceManager?.destroyWorkspace(this.id);
+    // ... cleanup
+  }
+}
+
+// In tests
+afterEach(() => session.destroy());
+```
+
+**Why this is wrong:**
+- Production class polluted with test-only code
+- Dangerous if accidentally called in production
+- Violates YAGNI and separation of concerns
+- Confuses object lifecycle with entity lifecycle
+
+**The fix:**
+```typescript
+// ✅ GOOD: Test utilities handle test cleanup
+// Session has no destroy() - it's stateless in production
+
+// In test-utils/
+export async function cleanupSession(session: Session) {
+  const workspace = session.getWorkspaceInfo();
+  if (workspace) {
+    await workspaceManager.destroyWorkspace(workspace.id);
+  }
+}
+
+// In tests
+afterEach(() => cleanupSession(session));
+```
+
+### Gate Function
+
+```
+BEFORE adding any method to production class:
+  Ask: "Is this only used by tests?"
+
+  IF yes:
+    STOP - Don't add it
+    Put it in test utilities instead
+
+  Ask: "Does this class own this resource's lifecycle?"
+
+  IF no:
+    STOP - Wrong class for this method
+```
+
+## Anti-Pattern 3: Mocking Without Understanding
+
+**The violation:**
+```typescript
+// ❌ BAD: Mock breaks test logic
+test('detects duplicate server', () => {
+  // Mock prevents config write that test depends on!
+  vi.mock('ToolCatalog', () => ({
+    discoverAndCacheTools: vi.fn().mockResolvedValue(undefined)
+  }));
+
+  await addServer(config);
+  await addServer(config);  // Should throw - but won't!
+});
+```
+
+**Why this is wrong:**
+- Mocked method had side effect test depended on (writing config)
+- Over-mocking to "be safe" breaks actual behavior
+- Test passes for wrong reason or fails mysteriously
+
+**The fix:**
+```typescript
+// ✅ GOOD: Mock at correct level
+test('detects duplicate server', () => {
+  // Mock the slow part, preserve behavior test needs
+  vi.mock('MCPServerManager'); // Just mock slow server startup
+
+  await addServer(config);  // Config written
+  await addServer(config);  // Duplicate detected ✓
+});
+```
+
+### Gate Function
+
+```
+BEFORE mocking any method:
+  STOP - Don't mock yet
+
+  1. Ask: "What side effects does the real method have?"
+  2. Ask: "Does this test depend on any of those side effects?"
+  3. Ask: "Do I fully understand what this test needs?"
+
+  IF depends on side effects:
+    Mock at lower level (the actual slow/external operation)
+    OR use test doubles that preserve necessary behavior
+    NOT the high-level method the test depends on
+
+  IF unsure what test depends on:
+    Run test with real implementation FIRST
+    Observe what actually needs to happen
+    THEN add minimal mocking at the right level
+
+  Red flags:
+    - "I'll mock this to be safe"
+    - "This might be slow, better mock it"
+    - Mocking without understanding the dependency chain
+```
+
+## Anti-Pattern 4: Incomplete Mocks
+
+**The violation:**
+```typescript
+// ❌ BAD: Partial mock - only fields you think you need
+const mockResponse = {
+  status: 'success',
+  data: { userId: '123', name: 'Alice' }
+  // Missing: metadata that downstream code uses
+};
+
+// Later: breaks when code accesses response.metadata.requestId
+```
+
+**Why this is wrong:**
+- **Partial mocks hide structural assumptions** - You only mocked fields you know about
+- **Downstream code may depend on fields you didn't include** - Silent failures
+- **Tests pass but integration fails** - Mock incomplete, real API complete
+- **False confidence** - Test proves nothing about real behavior
+
+**The Iron Rule:** Mock the COMPLETE data structure as it exists in reality, not just fields your immediate test uses.
+
+**The fix:**
+```typescript
+// ✅ GOOD: Mirror real API completeness
+const mockResponse = {
+  status: 'success',
+  data: { userId: '123', name: 'Alice' },
+  metadata: { requestId: 'req-789', timestamp: 1234567890 }
+  // All fields real API returns
+};
+```
+
+### Gate Function
+
+```
+BEFORE creating mock responses:
+  Check: "What fields does the real API response contain?"
+
+  Actions:
+    1. Examine actual API response from docs/examples
+    2. Include ALL fields system might consume downstream
+    3. Verify mock matches real response schema completely
+
+  Critical:
+    If you're creating a mock, you must understand the ENTIRE structure
+    Partial mocks fail silently when code depends on omitted fields
+
+  If uncertain: Include all documented fields
+```
+
+## Anti-Pattern 5: Integration Tests as Afterthought
+
+**The violation:**
+```
+✅ Implementation complete
+❌ No tests written
+"Ready for testing"
+```
+
+**Why this is wrong:**
+- Testing is part of implementation, not optional follow-up
+- TDD would have caught this
+- Can't claim complete without tests
+
+**The fix:**
+```
+TDD cycle:
+1. Write failing test
+2. Implement to pass
+3. Refactor
+4. THEN claim complete
+```
+
+## When Mocks Become Too Complex
+
+**Warning signs:**
+- Mock setup longer than test logic
+- Mocking everything to make test pass
+- Mocks missing methods real components have
+- Test breaks when mock changes
+
+**your human partner's question:** "Do we need to be using a mock here?"
+
+**Consider:** Integration tests with real components often simpler than complex mocks
+
+## TDD Prevents These Anti-Patterns
+
+**Why TDD helps:**
+1. **Write test first** → Forces you to think about what you're actually testing
+2. **Watch it fail** → Confirms test tests real behavior, not mocks
+3. **Minimal implementation** → No test-only methods creep in
+4. **Real dependencies** → You see what the test actually needs before mocking
+
+**If you're testing mock behavior, you violated TDD** - you added mocks without watching test fail against real code first.
+
+## Quick Reference
+
+| Anti-Pattern | Fix |
+|--------------|-----|
+| Assert on mock elements | Test real component or unmock it |
+| Test-only methods in production | Move to test utilities |
+| Mock without understanding | Understand dependencies first, mock minimally |
+| Incomplete mocks | Mirror real API completely |
+| Tests as afterthought | TDD - tests first |
+| Over-complex mocks | Consider integration tests |
+
+## Red Flags
+
+- Assertion checks for `*-mock` test IDs
+- Methods only called in test files
+- Mock setup is >50% of test
+- Test fails when you remove mock
+- Can't explain why mock is needed
+- Mocking "just to be safe"
+
+## The Bottom Line
+
+**Mocks are tools to isolate, not things to test.**
+
+If TDD reveals you're testing mock behavior, you've gone wrong.
+
+Fix: Test real behavior or question why you're mocking at all.

+name: using-git-worktrees
+description: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback
+---
+
+# Using Git Worktrees
+
+## Overview
+
+Ensure work happens in an isolated workspace. Prefer your platform's native worktree tools. Fall back to manual git worktrees only when no native tool is available.
+
+**Core principle:** Detect existing isolation first. Then use native tools. Then fall back to git. Never fight the harness.
+
+**Announce at start:** "I'm using the using-git-worktrees skill to set up an isolated workspace."
+
+## Step 0: Detect Existing Isolation
+
+**Before creating anything, check if you are already in an isolated workspace.**
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+BRANCH=$(git branch --show-current)
+```
+
+**Submodule guard:** `GIT_DIR != GIT_COMMON` is also true inside git submodules. Before concluding "already in a worktree," verify you are not in a submodule:
+
+```bash
+# If this returns a path, you're in a submodule, not a worktree — treat as normal repo
+git rev-parse --show-superproject-working-tree 2>/dev/null
+```
+
+**If `GIT_DIR != GIT_COMMON` (and not a submodule):** You are already in a linked worktree. Skip to Step 3 (Project Setup). Do NOT create another worktree.
+
+Report with branch state:
+- On a branch: "Already in isolated workspace at `<path>` on branch `<name>`."
+- Detached HEAD: "Already in isolated workspace at `<path>` (detached HEAD, externally managed). Branch creation needed at finish time."
+
+**If `GIT_DIR == GIT_COMMON` (or in a submodule):** You are in a normal repo checkout.
+
+Has the user already indicated their worktree preference in your instructions? If not, ask for consent before creating a worktree:
+
+> "Would you like me to set up an isolated worktree? It protects your current branch from changes."
+
+Honor any existing declared preference without asking. If the user declines consent, work in place and skip to Step 3.
+
+## Step 1: Create Isolated Workspace
+
+**You have two mechanisms. Try them in this order.**
+
+### 1a. Native Worktree Tools (preferred)
+
+The user has asked for an isolated workspace (Step 0 consent). Do you already have a way to create a worktree? It might be a tool with a name like `EnterWorktree`, `WorktreeCreate`, a `/worktree` command, or a `--worktree` flag. If you do, use it and skip to Step 3.
+
+Native tools handle directory placement, branch creation, and cleanup automatically. Using `git worktree add` when you have a native tool creates phantom state your harness can't see or manage.
+
+Only proceed to Step 1b if you have no native worktree tool available.
+
+### 1b. Git Worktree Fallback
+
+**Only use this if Step 1a does not apply** — you have no native worktree tool available. Create a worktree manually using git.
+
+#### Directory Selection
+
+Follow this priority order. Explicit user preference always beats observed filesystem state.
+
+1. **Check your instructions for a declared worktree directory preference.** If the user has already specified one, use it without asking.
+
+2. **Check for an existing project-local worktree directory:**
+   ```bash
+   ls -d .worktrees 2>/dev/null     # Preferred (hidden)
+   ls -d worktrees 2>/dev/null      # Alternative
+   ```
+   If found, use it. If both exist, `.worktrees` wins.
+
+3. **Check for an existing global directory:**
+   ```bash
+   project=$(basename "$(git rev-parse --show-toplevel)")
+   ls -d ~/.config/superpowers/worktrees/$project 2>/dev/null
+   ```
+   If found, use it (backward compatibility with legacy global path).
+
+4. **If there is no other guidance available**, default to `.worktrees/` at the project root.
+
+#### Safety Verification (project-local directories only)
+
+**MUST verify directory is ignored before creating worktree:**
+
+```bash
+git check-ignore -q .worktrees 2>/dev/null || git check-ignore -q worktrees 2>/dev/null
+```
+
+**If NOT ignored:** Add to .gitignore, commit the change, then proceed.
+
+**Why critical:** Prevents accidentally committing worktree contents to repository.
+
+Global directories (`~/.config/superpowers/worktrees/`) need no verification.
+
+#### Create the Worktree
+
+```bash
+project=$(basename "$(git rev-parse --show-toplevel)")
+
+# Determine path based on chosen location
+# For project-local: path="$LOCATION/$BRANCH_NAME"
+# For global: path="~/.config/superpowers/worktrees/$project/$BRANCH_NAME"
+
+git worktree add "$path" -b "$BRANCH_NAME"
+cd "$path"
+```
+
+**Sandbox fallback:** If `git worktree add` fails with a permission error (sandbox denial), tell the user the sandbox blocked worktree creation and you're working in the current directory instead. Then run setup and baseline tests in place.
+
+## Step 3: Project Setup
+
+Auto-detect and run appropriate setup:
+
+```bash
+# Node.js
+if [ -f package.json ]; then npm install; fi
+
+# Rust
+if [ -f Cargo.toml ]; then cargo build; fi
+
+# Python
+if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
+if [ -f pyproject.toml ]; then poetry install; fi
+
+# Go
+if [ -f go.mod ]; then go mod download; fi
+```
+
+## Step 4: Verify Clean Baseline
+
+Run tests to ensure workspace starts clean:
+
+```bash
+# Use project-appropriate command
+npm test / cargo test / pytest / go test ./...
+```
+
+**If tests fail:** Report failures, ask whether to proceed or investigate.
+
+**If tests pass:** Report ready.
+
+### Report
+
+```
+Worktree ready at <full-path>
+Tests passing (<N> tests, 0 failures)
+Ready to implement <feature-name>
+```
+
+## Quick Reference
+
+| Situation | Action |
+|-----------|--------|
+| Already in linked worktree | Skip creation (Step 0) |
+| In a submodule | Treat as normal repo (Step 0 guard) |
+| Native worktree tool available | Use it (Step 1a) |
+| No native tool | Git worktree fallback (Step 1b) |
+| `.worktrees/` exists | Use it (verify ignored) |
+| `worktrees/` exists | Use it (verify ignored) |
+| Both exist | Use `.worktrees/` |
+| Neither exists | Check instruction file, then default `.worktrees/` |
+| Global path exists | Use it (backward compat) |
+| Directory not ignored | Add to .gitignore + commit |
+| Permission error on create | Sandbox fallback, work in place |
+| Tests fail during baseline | Report failures + ask |
+| No package.json/Cargo.toml | Skip dependency install |
+
+## Common Mistakes
+
+### Fighting the harness
+
+- **Problem:** Using `git worktree add` when the platform already provides isolation
+- **Fix:** Step 0 detects existing isolation. Step 1a defers to native tools.
+
+### Skipping detection
+
+- **Problem:** Creating a nested worktree inside an existing one
+- **Fix:** Always run Step 0 before creating anything
+
+### Skipping ignore verification
+
+- **Problem:** Worktree contents get tracked, pollute git status
+- **Fix:** Always use `git check-ignore` before creating project-local worktree
+
+### Assuming directory location
+
+- **Problem:** Creates inconsistency, violates project conventions
+- **Fix:** Follow priority: existing > global legacy > instruction file > default
+
+### Proceeding with failing tests
+
+- **Problem:** Can't distinguish new bugs from pre-existing issues
+- **Fix:** Report failures, get explicit permission to proceed
+
+## Red Flags
+
+**Never:**
+- Create a worktree when Step 0 detects existing isolation
+- Use `git worktree add` when you have a native worktree tool (e.g., `EnterWorktree`). This is the #1 mistake — if you have it, use it.
+- Skip Step 1a by jumping straight to Step 1b's git commands
+- Create worktree without verifying it's ignored (project-local)
+- Skip baseline test verification
+- Proceed with failing tests without asking
+
+**Always:**
+- Run Step 0 detection first
+- Prefer native tools over git fallback
+- Follow directory priority: existing > global legacy > instruction file > default
+- Verify directory is ignored for project-local
+- Auto-detect and run project setup
+- Verify clean test baseline

+description: Use when starting any conversation - establishes how to find and use skills, requiring Skill tool invocation before ANY response including clarifying questions
+---
+
+<SUBAGENT-STOP>
+If you were dispatched as a subagent to execute a specific task, skip this skill.
+</SUBAGENT-STOP>
+
+<EXTREMELY-IMPORTANT>
+If you think there is even a 1% chance a skill might apply to what you are doing, you ABSOLUTELY MUST invoke the skill.
+
+IF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.
+
+This is not negotiable. This is not optional. You cannot rationalize your way out of this.
+</EXTREMELY-IMPORTANT>
+
+## Instruction Priority
+
+Superpowers skills override default system prompt behavior, but **user instructions always take precedence**:
+
+1. **User's explicit instructions** (CLAUDE.md, GEMINI.md, AGENTS.md, direct requests) — highest priority
+2. **Superpowers skills** — override default system behavior where they conflict
+3. **Default system prompt** — lowest priority
+
+If CLAUDE.md, GEMINI.md, or AGENTS.md says "don't use TDD" and a skill says "always use TDD," follow the user's instructions. The user is in control.
+
+## How to Access Skills
+
+**In Claude Code:** Use the `Skill` tool. When you invoke a skill, its content is loaded and presented to you—follow it directly. Never use the Read tool on skill files.
+
+**In Copilot CLI:** Use the `skill` tool. Skills are auto-discovered from installed plugins. The `skill` tool works the same as Claude Code's `Skill` tool.
+
+**In Gemini CLI:** Skills activate via the `activate_skill` tool. Gemini loads skill metadata at session start and activates the full content on demand.
+
+**In other environments:** Check your platform's documentation for how skills are loaded.
+
+## Platform Adaptation
+
+Skills use Claude Code tool names. Non-CC platforms: see `references/copilot-tools.md` (Copilot CLI), `references/codex-tools.md` (Codex) for tool equivalents. Gemini CLI users get the tool mapping loaded automatically via GEMINI.md.
+
+# Using Skills
+
+## The Rule
+
+**Invoke relevant or requested skills BEFORE any response or action.** Even a 1% chance a skill might apply means that you should invoke the skill to check. If an invoked skill turns out to be wrong for the situation, you don't need to use it.
+
+```dot
+digraph skill_flow {
+    "User message received" [shape=doublecircle];
+    "About to EnterPlanMode?" [shape=doublecircle];
+    "Already brainstormed?" [shape=diamond];
+    "Invoke brainstorming skill" [shape=box];
+    "Might any skill apply?" [shape=diamond];
+    "Invoke Skill tool" [shape=box];
+    "Announce: 'Using [skill] to [purpose]'" [shape=box];
+    "Has checklist?" [shape=diamond];
+    "Create TodoWrite todo per item" [shape=box];
+    "Follow skill exactly" [shape=box];
+    "Respond (including clarifications)" [shape=doublecircle];
+
+    "About to EnterPlanMode?" -> "Already brainstormed?";
+    "Already brainstormed?" -> "Invoke brainstorming skill" [label="no"];
+    "Already brainstormed?" -> "Might any skill apply?" [label="yes"];
+    "Invoke brainstorming skill" -> "Might any skill apply?";
+
+    "User message received" -> "Might any skill apply?";
+    "Might any skill apply?" -> "Invoke Skill tool" [label="yes, even 1%"];
+    "Might any skill apply?" -> "Respond (including clarifications)" [label="definitely not"];
+    "Invoke Skill tool" -> "Announce: 'Using [skill] to [purpose]'";
+    "Announce: 'Using [skill] to [purpose]'" -> "Has checklist?";
+    "Has checklist?" -> "Create TodoWrite todo per item" [label="yes"];
+    "Has checklist?" -> "Follow skill exactly" [label="no"];
+    "Create TodoWrite todo per item" -> "Follow skill exactly";
+}
+```
+
+## Red Flags
+
+These thoughts mean STOP—you're rationalizing:
+
+| Thought | Reality |
+|---------|---------|
+| "This is just a simple question" | Questions are tasks. Check for skills. |
+| "I need more context first" | Skill check comes BEFORE clarifying questions. |
+| "Let me explore the codebase first" | Skills tell you HOW to explore. Check first. |
+| "I can check git/files quickly" | Files lack conversation context. Check for skills. |
+| "Let me gather information first" | Skills tell you HOW to gather information. |
+| "This doesn't need a formal skill" | If a skill exists, use it. |
+| "I remember this skill" | Skills evolve. Read current version. |
+| "This doesn't count as a task" | Action = task. Check for skills. |
+| "The skill is overkill" | Simple things become complex. Use it. |
+| "I'll just do this one thing first" | Check BEFORE doing anything. |
+| "This feels productive" | Undisciplined action wastes time. Skills prevent this. |
+| "I know what that means" | Knowing the concept ≠ using the skill. Invoke it. |
+
+## Skill Priority
+
+When multiple skills could apply, use this order:
+
+1. **Process skills first** (brainstorming, debugging) - these determine HOW to approach the task
+2. **Implementation skills second** (frontend-design, mcp-builder) - these guide execution
+
+"Let's build X" → brainstorming first, then implementation skills.
+"Fix this bug" → debugging first, then domain-specific skills.
+
+## Skill Types
+
+**Rigid** (TDD, debugging): Follow exactly. Don't adapt away discipline.
+
+**Flexible** (patterns): Adapt principles to context.
+
+The skill itself tells you which.
+
+## User Instructions
+
+Instructions say WHAT, not HOW. "Add X" or "Fix Y" doesn't mean skip workflows.

+# Codex Tool Mapping
+
+Skills use Claude Code tool names. When you encounter these in a skill, use your platform equivalent:
+
+| Skill references | Codex equivalent |
+|-----------------|------------------|
+| `Task` tool (dispatch subagent) | `spawn_agent` (see [Subagent dispatch requires multi-agent support](#subagent-dispatch-requires-multi-agent-support)) |
+| Multiple `Task` calls (parallel) | Multiple `spawn_agent` calls |
+| Task returns result | `wait_agent` |
+| Task completes automatically | `close_agent` to free slot |
+| `TodoWrite` (task tracking) | `update_plan` |
+| `Skill` tool (invoke a skill) | Skills load natively — just follow the instructions |
+| `Read`, `Write`, `Edit` (files) | Use your native file tools |
+| `Bash` (run commands) | Use your native shell tools |
+
+## Subagent dispatch requires multi-agent support
+
+Add to your Codex config (`~/.codex/config.toml`):
+
+```toml
+[features]
+multi_agent = true
+```
+
+This enables `spawn_agent`, `wait_agent`, and `close_agent` for skills like `dispatching-parallel-agents` and `subagent-driven-development`.
+
+Legacy note: Codex builds before `rust-v0.115.0` exposed spawned-agent
+waiting as `wait`. Current Codex uses `wait_agent` for spawned agents. The
+`wait` name now belongs to code-mode `exec/wait`, which resumes a yielded exec
+cell by `cell_id`; it is not the spawned-agent result tool.
+
+## Environment Detection
+
+Skills that create worktrees or finish branches should detect their
+environment with read-only git commands before proceeding:
+
+```bash
+GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
+GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
+BRANCH=$(git branch --show-current)
+```
+
+- `GIT_DIR != GIT_COMMON` → already in a linked worktree (skip creation)
+- `BRANCH` empty → detached HEAD (cannot branch/push/PR from sandbox)
+
+See `using-git-worktrees` Step 0 and `finishing-a-development-branch`
+Step 1 for how each skill uses these signals.
+
+## Codex App Finishing
+
+When the sandbox blocks branch/push operations (detached HEAD in an
+externally managed worktree), the agent commits all work and informs
+the user to use the App's native controls:
+
+- **"Create branch"** — names the branch, then commit/push/PR via App UI
+- **"Hand off to local"** — transfers work to the user's local checkout
+
+The agent can still run tests, stage files, and output suggested branch
+names, commit messages, and PR descriptions for the user to copy.

+# Copilot CLI Tool Mapping
+
+Skills use Claude Code tool names. When you encounter these in a skill, use your platform equivalent:
+
+| Skill references | Copilot CLI equivalent |
+|-----------------|----------------------|
+| `Read` (file reading) | `view` |
+| `Write` (file creation) | `create` |
+| `Edit` (file editing) | `edit` |
+| `Bash` (run commands) | `bash` |
+| `Grep` (search file content) | `grep` |
+| `Glob` (search files by name) | `glob` |
+| `Skill` tool (invoke a skill) | `skill` |
+| `WebFetch` | `web_fetch` |
+| `Task` tool (dispatch subagent) | `task` with `agent_type: "general-purpose"` or `"explore"` |
+| Multiple `Task` calls (parallel) | Multiple `task` calls |
+| Task status/output | `read_agent`, `list_agents` |
+| `TodoWrite` (task tracking) | `sql` with built-in `todos` table |
+| `WebSearch` | No equivalent — use `web_fetch` with a search engine URL |
+| `EnterPlanMode` / `ExitPlanMode` | No equivalent — stay in the main session |
+
+## Async shell sessions
+
+Copilot CLI supports persistent async shell sessions, which have no direct Claude Code equivalent:
+
+| Tool | Purpose |
+|------|---------|
+| `bash` with `async: true` | Start a long-running command in the background |
+| `write_bash` | Send input to a running async session |
+| `read_bash` | Read output from an async session |
+| `stop_bash` | Terminate an async session |
+| `list_bash` | List all active shell sessions |
+
+## Additional Copilot CLI tools
+
+| Tool | Purpose |
+|------|---------|
+| `store_memory` | Persist facts about the codebase for future sessions |
+| `report_intent` | Update the UI status line with current intent |
+| `sql` | Query the session's SQLite database (todos, metadata) |
+| `fetch_copilot_cli_documentation` | Look up Copilot CLI documentation |
+| GitHub MCP tools (`github-mcp-server-*`) | Native GitHub API access (issues, PRs, code search) |

+# Gemini CLI Tool Mapping
+
+Skills use Claude Code tool names. When you encounter these in a skill, use your platform equivalent:
+
+| Skill references | Gemini CLI equivalent |
+|-----------------|----------------------|
+| `Read` (file reading) | `read_file` |
+| `Write` (file creation) | `write_file` |
+| `Edit` (file editing) | `replace` |
+| `Bash` (run commands) | `run_shell_command` |
+| `Grep` (search file content) | `grep_search` |
+| `Glob` (search files by name) | `glob` |
+| `TodoWrite` (task tracking) | `write_todos` |
+| `Skill` tool (invoke a skill) | `activate_skill` |
+| `WebSearch` | `google_web_search` |
+| `WebFetch` | `web_fetch` |
+| `Task` tool (dispatch subagent) | `@agent-name` (see [Subagent support](#subagent-support)) |
+
+## Subagent support
+
+Gemini CLI supports subagents natively via the `@` syntax. Use the built-in `@generalist` agent to dispatch any task — it has access to all tools and follows the prompt you provide.
+
+When a skill says to dispatch a named agent type, use `@generalist` with the full prompt from the skill's prompt template:
+
+| Skill instruction | Gemini CLI equivalent |
+|-------------------|----------------------|
+| `Task tool (superpowers:implementer)` | `@generalist` with the filled `implementer-prompt.md` template |
+| `Task tool (superpowers:spec-reviewer)` | `@generalist` with the filled `spec-reviewer-prompt.md` template |
+| `Task tool (superpowers:code-reviewer)` | `@code-reviewer` (bundled agent) or `@generalist` with the filled review prompt |
+| `Task tool (superpowers:code-quality-reviewer)` | `@generalist` with the filled `code-quality-reviewer-prompt.md` template |
+| `Task tool (general-purpose)` with inline prompt | `@generalist` with your inline prompt |
+
+### Prompt filling
+
+Skills provide prompt templates with placeholders like `{WHAT_WAS_IMPLEMENTED}` or `[FULL TEXT of task]`. Fill all placeholders and pass the complete prompt as the message to `@generalist`. The prompt template itself contains the agent's role, review criteria, and expected output format — `@generalist` will follow it.
+
+### Parallel dispatch
+
+Gemini CLI supports parallel subagent dispatch. When a skill asks you to dispatch multiple independent subagent tasks in parallel, request all of those `@generalist` or named subagent tasks together in the same prompt. Keep dependent tasks sequential, but do not serialize independent subagent tasks just to preserve a simpler history.
+
+## Additional Gemini CLI tools
+
+These tools are available in Gemini CLI but have no Claude Code equivalent:
+
+| Tool | Purpose |
+|------|---------|
+| `list_directory` | List files and subdirectories |
+| `save_memory` | Persist facts to GEMINI.md across sessions |
+| `ask_user` | Request structured input from the user |
+| `tracker_create_task` | Rich task management (create, update, list, visualize) |
+| `enter_plan_mode` / `exit_plan_mode` | Switch to read-only research mode before making changes |

+name: verification-before-completion
+description: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
+---
+
+# Verification Before Completion
+
+## Overview
+
+Claiming work is complete without verification is dishonesty, not efficiency.
+
+**Core principle:** Evidence before claims, always.
+
+**Violating the letter of this rule is violating the spirit of this rule.**
+
+## The Iron Law
+
+```
+NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE
+```
+
+If you haven't run the verification command in this message, you cannot claim it passes.
+
+## The Gate Function
+
+```
+BEFORE claiming any status or expressing satisfaction:
+
+1. IDENTIFY: What command proves this claim?
+2. RUN: Execute the FULL command (fresh, complete)
+3. READ: Full output, check exit code, count failures
+4. VERIFY: Does output confirm the claim?
+   - If NO: State actual status with evidence
+   - If YES: State claim WITH evidence
+5. ONLY THEN: Make the claim
+
+Skip any step = lying, not verifying
+```
+
+## Common Failures
+
+| Claim | Requires | Not Sufficient |
+|-------|----------|----------------|
+| Tests pass | Test command output: 0 failures | Previous run, "should pass" |
+| Linter clean | Linter output: 0 errors | Partial check, extrapolation |
+| Build succeeds | Build command: exit 0 | Linter passing, logs look good |
+| Bug fixed | Test original symptom: passes | Code changed, assumed fixed |
+| Regression test works | Red-green cycle verified | Test passes once |
+| Agent completed | VCS diff shows changes | Agent reports "success" |
+| Requirements met | Line-by-line checklist | Tests passing |
+
+## Red Flags - STOP
+
+- Using "should", "probably", "seems to"
+- Expressing satisfaction before verification ("Great!", "Perfect!", "Done!", etc.)
+- About to commit/push/PR without verification
+- Trusting agent success reports
+- Relying on partial verification
+- Thinking "just this once"
+- Tired and wanting work over
+- **ANY wording implying success without having run verification**
+
+## Rationalization Prevention
+
+| Excuse | Reality |
+|--------|---------|
+| "Should work now" | RUN the verification |
+| "I'm confident" | Confidence ≠ evidence |
+| "Just this once" | No exceptions |
+| "Linter passed" | Linter ≠ compiler |
+| "Agent said success" | Verify independently |
+| "I'm tired" | Exhaustion ≠ excuse |
+| "Partial check is enough" | Partial proves nothing |
+| "Different words so rule doesn't apply" | Spirit over letter |
+
+## Key Patterns
+
+**Tests:**
+```
+✅ [Run test command] [See: 34/34 pass] "All tests pass"
+❌ "Should pass now" / "Looks correct"
+```
+
+**Regression tests (TDD Red-Green):**
+```
+✅ Write → Run (pass) → Revert fix → Run (MUST FAIL) → Restore → Run (pass)
+❌ "I've written a regression test" (without red-green verification)
+```
+
+**Build:**
+```
+✅ [Run build] [See: exit 0] "Build passes"
+❌ "Linter passed" (linter doesn't check compilation)
+```
+
+**Requirements:**
+```
+✅ Re-read plan → Create checklist → Verify each → Report gaps or completion
+❌ "Tests pass, phase complete"
+```
+
+**Agent delegation:**
+```
+✅ Agent reports success → Check VCS diff → Verify changes → Report actual state
+❌ Trust agent report
+```
+
+## Why This Matters
+
+From 24 failure memories:
+- your human partner said "I don't believe you" - trust broken
+- Undefined functions shipped - would crash
+- Missing requirements shipped - incomplete features
+- Time wasted on false completion → redirect → rework
+- Violates: "Honesty is a core value. If you lie, you'll be replaced."
+
+## When To Apply
+
+**ALWAYS before:**
+- ANY variation of success/completion claims
+- ANY expression of satisfaction
+- ANY positive statement about work state
+- Committing, PR creation, task completion
+- Moving to next task
+- Delegating to agents
+
+**Rule applies to:**
+- Exact phrases
+- Paraphrases and synonyms
+- Implications of success
+- ANY communication suggesting completion/correctness
+
+## The Bottom Line
+
+**No shortcuts for verification.**
+
+Run the command. Read the output. THEN claim the result.
+
+This is non-negotiable.

+description: Use when you have a spec or requirements for a multi-step task, before touching code
+---
+
+# Writing Plans
+
+## Overview
+
+Write comprehensive implementation plans assuming the engineer has zero context for our codebase and questionable taste. Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.
+
+Assume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.
+
+**Announce at start:** "I'm using the writing-plans skill to create the implementation plan."
+
+**Context:** If working in an isolated worktree, it should have been created via the `superpowers:using-git-worktrees` skill at execution time.
+
+**Save plans to:** `docs/superpowers/plans/YYYY-MM-DD-<feature-name>.md`
+- (User preferences for plan location override this default)
+
+## Scope Check
+
+If the spec covers multiple independent subsystems, it should have been broken into sub-project specs during brainstorming. If it wasn't, suggest breaking this into separate plans — one per subsystem. Each plan should produce working, testable software on its own.
+
+## File Structure
+
+Before defining tasks, map out which files will be created or modified and what each one is responsible for. This is where decomposition decisions get locked in.
+
+- Design units with clear boundaries and well-defined interfaces. Each file should have one clear responsibility.
+- You reason best about code you can hold in context at once, and your edits are more reliable when files are focused. Prefer smaller, focused files over large ones that do too much.
+- Files that change together should live together. Split by responsibility, not by technical layer.
+- In existing codebases, follow established patterns. If the codebase uses large files, don't unilaterally restructure - but if a file you're modifying has grown unwieldy, including a split in the plan is reasonable.
+
+This structure informs the task decomposition. Each task should produce self-contained changes that make sense independently.
+
+## Bite-Sized Task Granularity
+
+**Each step is one action (2-5 minutes):**
+- "Write the failing test" - step
+- "Run it to make sure it fails" - step
+- "Implement the minimal code to make the test pass" - step
+- "Run the tests and make sure they pass" - step
+- "Commit" - step
+
+## Plan Document Header
+
+**Every plan MUST start with this header:**
+
+```markdown
+# [Feature Name] Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

+- Modify: `exact/path/to/existing.py:123-145`
+- Test: `tests/exact/path/to/test.py`
+
+- [ ] **Step 1: Write the failing test**
+
+```python
+def test_specific_behavior():
+    result = function(input)
+    assert result == expected
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `pytest tests/path/test.py::test_name -v`
+Expected: FAIL with "function not defined"
+
+- [ ] **Step 3: Write minimal implementation**
+
+```python
+def function(input):
+    return expected
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `pytest tests/path/test.py::test_name -v`

+
+- [ ] **Step 5: Commit**
+
+```bash
+git add tests/path/test.py src/path/file.py
+git commit -m "feat: add specific feature"
+```
+````
+
+## No Placeholders
+
+Every step must contain the actual content an engineer needs. These are **plan failures** — never write them:
+- "TBD", "TODO", "implement later", "fill in details"
+- "Add appropriate error handling" / "add validation" / "handle edge cases"
+- "Write tests for the above" (without actual test code)
+- "Similar to Task N" (repeat the code — the engineer may be reading tasks out of order)
+- Steps that describe what to do without showing how (code blocks required for code steps)
+- References to types, functions, or methods not defined in any task
+
+## Remember
+- Exact file paths always
+- Complete code in every step — if a step changes code, show the code
+- Exact commands with expected output
+- DRY, YAGNI, TDD, frequent commits
+
+## Self-Review
+
+After writing the complete plan, look at the spec with fresh eyes and check the plan against it. This is a checklist you run yourself — not a subagent dispatch.
+
+**1. Spec coverage:** Skim each section/requirement in the spec. Can you point to a task that implements it? List any gaps.
+
+**2. Placeholder scan:** Search your plan for red flags — any of the patterns from the "No Placeholders" section above. Fix them.
+
+**3. Type consistency:** Do the types, method signatures, and property names you used in later tasks match what you defined in earlier tasks? A function called `clearLayers()` in Task 3 but `clearFullLayers()` in Task 7 is a bug.
+
+If you find issues, fix them inline. No need to re-review — just fix and move on. If you find a spec requirement with no task, add the task.
+
+## Execution Handoff
+
+After saving the plan, offer execution choice:
+
+**"Plan complete and saved to `docs/superpowers/plans/<filename>.md`. Two execution options:**
+
+**1. Subagent-Driven (recommended)** - I dispatch a fresh subagent per task, review between tasks, fast iteration
+
+**2. Inline Execution** - Execute tasks in this session using executing-plans, batch execution with checkpoints
+
+**Which approach?"**
+
+**If Subagent-Driven chosen:**
+- **REQUIRED SUB-SKILL:** Use superpowers:subagent-driven-development
+- Fresh subagent per task + two-stage review
+
+**If Inline Execution chosen:**
+- **REQUIRED SUB-SKILL:** Use superpowers:executing-plans
+- Batch execution with checkpoints for review

+# Plan Document Reviewer Prompt Template
+
+Use this template when dispatching a plan document reviewer subagent.
+
+**Purpose:** Verify the plan is complete, matches the spec, and has proper task decomposition.
+
+**Dispatch after:** The complete plan is written.
+
+```
+Task tool (general-purpose):
+  description: "Review plan document"
+  prompt: |
+    You are a plan document reviewer. Verify this plan is complete and ready for implementation.
+
+    **Plan to review:** [PLAN_FILE_PATH]
+    **Spec for reference:** [SPEC_FILE_PATH]
+
+    ## What to Check
+
+    | Category | What to Look For |
+    |----------|------------------|
+    | Completeness | TODOs, placeholders, incomplete tasks, missing steps |
+    | Spec Alignment | Plan covers spec requirements, no major scope creep |
+    | Task Decomposition | Tasks have clear boundaries, steps are actionable |
+    | Buildability | Could an engineer follow this plan without getting stuck? |
+
+    ## Calibration
+
+    **Only flag issues that would cause real problems during implementation.**
+    An implementer building the wrong thing or getting stuck is an issue.
+    Minor wording, stylistic preferences, and "nice to have" suggestions are not.
+
+    Approve unless there are serious gaps — missing requirements from the spec,
+    contradictory steps, placeholder content, or tasks so vague they can't be acted on.
+
+    ## Output Format
+
+    ## Plan Review
+
+    **Status:** Approved | Issues Found
+
+    **Issues (if any):**
+    - [Task X, Step Y]: [specific issue] - [why it matters for implementation]
+
+    **Recommendations (advisory, do not block approval):**
+    - [suggestions for improvement]
+```

+
+# Writing Skills
+
+## Overview
+
+**Writing skills IS Test-Driven Development applied to process documentation.**
+
+**Personal skills live in agent-specific directories (`~/.claude/skills` for Claude Code, `~/.agents/skills/` for Codex)** 
+
+You write test cases (pressure scenarios with subagents), watch them fail (baseline behavior), write the skill (documentation), watch tests pass (agents comply), and refactor (close loopholes).
+
+**Core principle:** If you didn't watch an agent fail without the skill, you don't know if the skill teaches the right thing.
+
+**REQUIRED BACKGROUND:** You MUST understand superpowers:test-driven-development before using this skill. That skill defines the fundamental RED-GREEN-REFACTOR cycle. This skill adapts TDD to documentation.
+
+**Official guidance:** For Anthropic's official skill authoring best practices, see anthropic-best-practices.md. This document provides additional patterns and guidelines that complement the TDD-focused approach in this skill.
+
+## What is a Skill?
+
+A **skill** is a reference guide for proven techniques, patterns, or tools. Skills help future Claude instances find and apply effective approaches.
+
+**Skills are:** Reusable techniques, patterns, tools, reference guides
+
+**Skills are NOT:** Narratives about how you solved a problem once
+
+## TDD Mapping for Skills
+
+| TDD Concept | Skill Creation |
+|-------------|----------------|
+| **Test case** | Pressure scenario with subagent |
+| **Production code** | Skill document (SKILL.md) |
+| **Test fails (RED)** | Agent violates rule without skill (baseline) |
+| **Test passes (GREEN)** | Agent complies with skill present |
+| **Refactor** | Close loopholes while maintaining compliance |
+| **Write test first** | Run baseline scenario BEFORE writing skill |
+| **Watch it fail** | Document exact rationalizations agent uses |
+| **Minimal code** | Write skill addressing those specific violations |
+| **Watch it pass** | Verify agent now complies |
+| **Refactor cycle** | Find new rationalizations → plug → re-verify |
+
+The entire skill creation process follows RED-GREEN-REFACTOR.
+
+## When to Create a Skill
+
+**Create when:**
+- Technique wasn't intuitively obvious to you
+- You'd reference this again across projects
+- Pattern applies broadly (not project-specific)
+- Others would benefit
+
+**Don't create for:**
+- One-off solutions
+- Standard practices well-documented elsewhere
+- Project-specific conventions (put in CLAUDE.md)
+- Mechanical constraints (if it's enforceable with regex/validation, automate it—save documentation for judgment calls)
+
+## Skill Types
+
+### Technique
+Concrete method with steps to follow (condition-based-waiting, root-cause-tracing)
+
+### Pattern
+Way of thinking about problems (flatten-with-flags, test-invariants)
+
+### Reference
+API docs, syntax guides, tool documentation (office docs)
+
+## Directory Structure
+
+
+```
+skills/
+  skill-name/
+    SKILL.md              # Main reference (required)
+    supporting-file.*     # Only if needed
+```
+
+**Flat namespace** - all skills in one searchable namespace
+
+**Separate files for:**
+1. **Heavy reference** (100+ lines) - API docs, comprehensive syntax
+2. **Reusable tools** - Scripts, utilities, templates
+
+**Keep inline:**
+- Principles and concepts
+- Code patterns (< 50 lines)
+- Everything else
+
+## SKILL.md Structure
+
+**Frontmatter (YAML):**
+- Two required fields: `name` and `description` (see [agentskills.io/specification](https://agentskills.io/specification) for all supported fields)
+- Max 1024 characters total
+- `name`: Use letters, numbers, and hyphens only (no parentheses, special chars)
+- `description`: Third-person, describes ONLY when to use (NOT what it does)
+  - Start with "Use when..." to focus on triggering conditions
+  - Include specific symptoms, situations, and contexts
+  - **NEVER summarize the skill's process or workflow** (see CSO section for why)
+  - Keep under 500 characters if possible
+
+```markdown
+---
+name: Skill-Name-With-Hyphens
+description: Use when [specific triggering conditions and symptoms]
+---
+
+# Skill Name
+
+## Overview
+What is this? Core principle in 1-2 sentences.
+
+## When to Use
+[Small inline flowchart IF decision non-obvious]
+
+Bullet list with SYMPTOMS and use cases
+When NOT to use
+
+## Core Pattern (for techniques/patterns)
+Before/after code comparison
+
+## Quick Reference
+Table or bullets for scanning common operations
+
+## Implementation
+Inline code for simple patterns
+Link to file for heavy reference or reusable tools
+
+## Common Mistakes
+What goes wrong + fixes
+
+## Real-World Impact (optional)
+Concrete results
+```
+
+
+## Claude Search Optimization (CSO)
+
+**Critical for discovery:** Future Claude needs to FIND your skill
+
+### 1. Rich Description Field
+
+**Purpose:** Claude reads description to decide which skills to load for a given task. Make it answer: "Should I read this skill right now?"
+
+**Format:** Start with "Use when..." to focus on triggering conditions
+
+**CRITICAL: Description = When to Use, NOT What the Skill Does**
+
+The description should ONLY describe triggering conditions. Do NOT summarize the skill's process or workflow in the description.
+
+**Why this matters:** Testing revealed that when a description summarizes the skill's workflow, Claude may follow the description instead of reading the full skill content. A description saying "code review between tasks" caused Claude to do ONE review, even though the skill's flowchart clearly showed TWO reviews (spec compliance then code quality).
+
+When the description was changed to just "Use when executing implementation plans with independent tasks" (no workflow summary), Claude correctly read the flowchart and followed the two-stage review process.
+
+**The trap:** Descriptions that summarize workflow create a shortcut Claude will take. The skill body becomes documentation Claude skips.
+
+```yaml
+# ❌ BAD: Summarizes workflow - Claude may follow this instead of reading skill
+description: Use when executing plans - dispatches subagent per task with code review between tasks
+
+# ❌ BAD: Too much process detail
+description: Use for TDD - write test first, watch it fail, write minimal code, refactor
+
+# ✅ GOOD: Just triggering conditions, no workflow summary
+description: Use when executing implementation plans with independent tasks in the current session
+
+# ✅ GOOD: Triggering conditions only
+description: Use when implementing any feature or bugfix, before writing implementation code
+```
+
+**Content:**
+- Use concrete triggers, symptoms, and situations that signal this skill applies
+- Describe the *problem* (race conditions, inconsistent behavior) not *language-specific symptoms* (setTimeout, sleep)
+- Keep triggers technology-agnostic unless the skill itself is technology-specific
+- If skill is technology-specific, make that explicit in the trigger
+- Write in third person (injected into system prompt)
+- **NEVER summarize the skill's process or workflow**
+
+```yaml
+# ❌ BAD: Too abstract, vague, doesn't include when to use
+description: For async testing
+
+# ❌ BAD: First person
+description: I can help you with async tests when they're flaky
+
+# ❌ BAD: Mentions technology but skill isn't specific to it
+description: Use when tests use setTimeout/sleep and are flaky
+
+# ✅ GOOD: Starts with "Use when", describes problem, no workflow
+description: Use when tests have race conditions, timing dependencies, or pass/fail inconsistently
+
+# ✅ GOOD: Technology-specific skill with explicit trigger
+description: Use when using React Router and handling authentication redirects
+```
+
+### 2. Keyword Coverage
+
+Use words Claude would search for:
+- Error messages: "Hook timed out", "ENOTEMPTY", "race condition"
+- Symptoms: "flaky", "hanging", "zombie", "pollution"
+- Synonyms: "timeout/hang/freeze", "cleanup/teardown/afterEach"
+- Tools: Actual commands, library names, file types
+
+### 3. Descriptive Naming
+
+**Use active voice, verb-first:**
+- ✅ `creating-skills` not `skill-creation`
+- ✅ `condition-based-waiting` not `async-test-helpers`
+
+### 4. Token Efficiency (Critical)
+
+**Problem:** getting-started and frequently-referenced skills load into EVERY conversation. Every token counts.
+
+**Target word counts:**
+- getting-started workflows: <150 words each
+- Frequently-loaded skills: <200 words total
+- Other skills: <500 words (still be concise)
+
+**Techniques:**
+
+**Move details to tool help:**
+```bash
+# ❌ BAD: Document all flags in SKILL.md
+search-conversations supports --text, --both, --after DATE, --before DATE, --limit N
+
+# ✅ GOOD: Reference --help
+search-conversations supports multiple modes and filters. Run --help for details.
+```
+
+**Use cross-references:**
+```markdown
+# ❌ BAD: Repeat workflow details
+When searching, dispatch subagent with template...
+[20 lines of repeated instructions]
+
+# ✅ GOOD: Reference other skill
+Always use subagents (50-100x context savings). REQUIRED: Use [other-skill-name] for workflow.
+```
+
+**Compress examples:**
+```markdown
+# ❌ BAD: Verbose example (42 words)
+your human partner: "How did we handle authentication errors in React Router before?"
+You: I'll search past conversations for React Router authentication patterns.
+[Dispatch subagent with search query: "React Router authentication error handling 401"]
+
+# ✅ GOOD: Minimal example (20 words)
+Partner: "How did we handle auth errors in React Router?"
+You: Searching...
+[Dispatch subagent → synthesis]
+```
+
+**Eliminate redundancy:**
+- Don't repeat what's in cross-referenced skills
+- Don't explain what's obvious from command
+- Don't include multiple examples of same pattern
+
+**Verification:**
+```bash
+wc -w skills/path/SKILL.md
+# getting-started workflows: aim for <150 each
+# Other frequently-loaded: aim for <200 total
+```
+
+**Name by what you DO or core insight:**
+- ✅ `condition-based-waiting` > `async-test-helpers`
+- ✅ `using-skills` not `skill-usage`
+- ✅ `flatten-with-flags` > `data-structure-refactoring`
+- ✅ `root-cause-tracing` > `debugging-techniques`
+
+**Gerunds (-ing) work well for processes:**
+- `creating-skills`, `testing-skills`, `debugging-with-logs`
+- Active, describes the action you're taking
+
+### 4. Cross-Referencing Other Skills
+
+**When writing documentation that references other skills:**
+
+Use skill name only, with explicit requirement markers:
+- ✅ Good: `**REQUIRED SUB-SKILL:** Use superpowers:test-driven-development`
+- ✅ Good: `**REQUIRED BACKGROUND:** You MUST understand superpowers:systematic-debugging`
+- ❌ Bad: `See skills/testing/test-driven-development` (unclear if required)
+- ❌ Bad: `@skills/testing/test-driven-development/SKILL.md` (force-loads, burns context)
+
+**Why no @ links:** `@` syntax force-loads files immediately, consuming 200k+ context before you need them.
+
+## Flowchart Usage
+
+```dot
+digraph when_flowchart {
+    "Need to show information?" [shape=diamond];
+    "Decision where I might go wrong?" [shape=diamond];
+    "Use markdown" [shape=box];
+    "Small inline flowchart" [shape=box];
+
+    "Need to show information?" -> "Decision where I might go wrong?" [label="yes"];
+    "Decision where I might go wrong?" -> "Small inline flowchart" [label="yes"];
+    "Decision where I might go wrong?" -> "Use markdown" [label="no"];
+}
+```
+
+**Use flowcharts ONLY for:**
+- Non-obvious decision points
+- Process loops where you might stop too early
+- "When to use A vs B" decisions
+
+**Never use flowcharts for:**
+- Reference material → Tables, lists
+- Code examples → Markdown blocks
+- Linear instructions → Numbered lists
+- Labels without semantic meaning (step1, helper2)
+
+See @graphviz-conventions.dot for graphviz style rules.
+
+**Visualizing for your human partner:** Use `render-graphs.js` in this directory to render a skill's flowcharts to SVG:
+```bash
+./render-graphs.js ../some-skill           # Each diagram separately
+./render-graphs.js ../some-skill --combine # All diagrams in one SVG
+```
+
+## Code Examples
+
+**One excellent example beats many mediocre ones**
+
+Choose most relevant language:
+- Testing techniques → TypeScript/JavaScript
+- System debugging → Shell/Python
+- Data processing → Python
+
+**Good example:**
+- Complete and runnable
+- Well-commented explaining WHY
+- From real scenario
+- Shows pattern clearly
+- Ready to adapt (not generic template)
+
+**Don't:**
+- Implement in 5+ languages
+- Create fill-in-the-blank templates
+- Write contrived examples
+
+You're good at porting - one great example is enough.
+
+## File Organization
+
+### Self-Contained Skill
+```
+defense-in-depth/
+  SKILL.md    # Everything inline
+```
+When: All content fits, no heavy reference needed
+
+### Skill with Reusable Tool
+```
+condition-based-waiting/
+  SKILL.md    # Overview + patterns
+  example.ts  # Working helpers to adapt
+```
+When: Tool is reusable code, not just narrative
+
+### Skill with Heavy Reference
+```
+pptx/
+  SKILL.md       # Overview + workflows
+  pptxgenjs.md   # 600 lines API reference
+  ooxml.md       # 500 lines XML structure
+  scripts/       # Executable tools
+```
+When: Reference material too large for inline
+
+## The Iron Law (Same as TDD)
+
+```
+NO SKILL WITHOUT A FAILING TEST FIRST
+```
+
+This applies to NEW skills AND EDITS to existing skills.
+
+Write skill before testing? Delete it. Start over.
+Edit skill without testing? Same violation.
+
+**No exceptions:**
+- Not for "simple additions"
+- Not for "just adding a section"
+- Not for "documentation updates"
+- Don't keep untested changes as "reference"
+- Don't "adapt" while running tests
+- Delete means delete
+
+**REQUIRED BACKGROUND:** The superpowers:test-driven-development skill explains why this matters. Same principles apply to documentation.
+
+## Testing All Skill Types
+
+Different skill types need different test approaches:
+
+### Discipline-Enforcing Skills (rules/requirements)
+
+**Examples:** TDD, verification-before-completion, designing-before-coding
+
+**Test with:**
+- Academic questions: Do they understand the rules?
+- Pressure scenarios: Do they comply under stress?
+- Multiple pressures combined: time + sunk cost + exhaustion
+- Identify rationalizations and add explicit counters
+
+**Success criteria:** Agent follows rule under maximum pressure
+
+### Technique Skills (how-to guides)
+
+**Examples:** condition-based-waiting, root-cause-tracing, defensive-programming
+
+**Test with:**
+- Application scenarios: Can they apply the technique correctly?
+- Variation scenarios: Do they handle edge cases?
+- Missing information tests: Do instructions have gaps?
+
+**Success criteria:** Agent successfully applies technique to new scenario
+
+### Pattern Skills (mental models)
+
+**Examples:** reducing-complexity, information-hiding concepts
+
+**Test with:**
+- Recognition scenarios: Do they recognize when pattern applies?
+- Application scenarios: Can they use the mental model?
+- Counter-examples: Do they know when NOT to apply?
+
+**Success criteria:** Agent correctly identifies when/how to apply pattern
+
+### Reference Skills (documentation/APIs)
+
+**Examples:** API documentation, command references, library guides
+
+**Test with:**
+- Retrieval scenarios: Can they find the right information?
+- Application scenarios: Can they use what they found correctly?
+- Gap testing: Are common use cases covered?
+
+**Success criteria:** Agent finds and correctly applies reference information
+
+## Common Rationalizations for Skipping Testing
+
+| Excuse | Reality |
+|--------|---------|
+| "Skill is obviously clear" | Clear to you ≠ clear to other agents. Test it. |
+| "It's just a reference" | References can have gaps, unclear sections. Test retrieval. |
+| "Testing is overkill" | Untested skills have issues. Always. 15 min testing saves hours. |
+| "I'll test if problems emerge" | Problems = agents can't use skill. Test BEFORE deploying. |
+| "Too tedious to test" | Testing is less tedious than debugging bad skill in production. |
+| "I'm confident it's good" | Overconfidence guarantees issues. Test anyway. |
+| "Academic review is enough" | Reading ≠ using. Test application scenarios. |
+| "No time to test" | Deploying untested skill wastes more time fixing it later. |
+
+**All of these mean: Test before deploying. No exceptions.**
+
+## Bulletproofing Skills Against Rationalization
+
+Skills that enforce discipline (like TDD) need to resist rationalization. Agents are smart and will find loopholes when under pressure.
+
+**Psychology note:** Understanding WHY persuasion techniques work helps you apply them systematically. See persuasion-principles.md for research foundation (Cialdini, 2021; Meincke et al., 2025) on authority, commitment, scarcity, social proof, and unity principles.
+
+### Close Every Loophole Explicitly
+
+Don't just state the rule - forbid specific workarounds:
+
+<Bad>
+```markdown
+Write code before test? Delete it.
+```
+</Bad>
+
+<Good>
+```markdown
+Write code before test? Delete it. Start over.
+
+**No exceptions:**
+- Don't keep it as "reference"
+- Don't "adapt" it while writing tests
+- Don't look at it
+- Delete means delete
+```
+</Good>
+
+### Address "Spirit vs Letter" Arguments
+
+Add foundational principle early:
+
+```markdown
+**Violating the letter of the rules is violating the spirit of the rules.**
+```
+
+This cuts off entire class of "I'm following the spirit" rationalizations.
+
+### Build Rationalization Table
+
+Capture rationalizations from baseline testing (see Testing section below). Every excuse agents make goes in the table:
+
+```markdown
+| Excuse | Reality |
+|--------|---------|
+| "Too simple to test" | Simple code breaks. Test takes 30 seconds. |
+| "I'll test after" | Tests passing immediately prove nothing. |
+| "Tests after achieve same goals" | Tests-after = "what does this do?" Tests-first = "what should this do?" |
+```
+
+### Create Red Flags List
+
+Make it easy for agents to self-check when rationalizing:
+
+```markdown
+## Red Flags - STOP and Start Over
+
+- Code before test
+- "I already manually tested it"
+- "Tests after achieve the same purpose"
+- "It's about spirit not ritual"
+- "This is different because..."
+
+**All of these mean: Delete code. Start over with TDD.**
+```
+
+### Update CSO for Violation Symptoms
+
+Add to description: symptoms of when you're ABOUT to violate the rule:
+
+```yaml
+description: use when implementing any feature or bugfix, before writing implementation code
+```
+
+## RED-GREEN-REFACTOR for Skills
+
+Follow the TDD cycle:
+
+### RED: Write Failing Test (Baseline)
+
+Run pressure scenario with subagent WITHOUT the skill. Document exact behavior:
+- What choices did they make?
+- What rationalizations did they use (verbatim)?
+- Which pressures triggered violations?
+
+This is "watch the test fail" - you must see what agents naturally do before writing the skill.
+
+### GREEN: Write Minimal Skill
+
+Write skill that addresses those specific rationalizations. Don't add extra content for hypothetical cases.
+
+Run same scenarios WITH skill. Agent should now comply.
+
+### REFACTOR: Close Loopholes
+
+Agent found new rationalization? Add explicit counter. Re-test until bulletproof.
+
+**Testing methodology:** See @testing-skills-with-subagents.md for the complete testing methodology:
+- How to write pressure scenarios
+- Pressure types (time, sunk cost, authority, exhaustion)
+- Plugging holes systematically
+- Meta-testing techniques
+
+## Anti-Patterns
+
+### ❌ Narrative Example
+"In session 2025-10-03, we found empty projectDir caused..."
+**Why bad:** Too specific, not reusable
+
+### ❌ Multi-Language Dilution
+example-js.js, example-py.py, example-go.go
+**Why bad:** Mediocre quality, maintenance burden
+
+### ❌ Code in Flowcharts
+```dot
+step1 [label="import fs"];
+step2 [label="read file"];
+```
+**Why bad:** Can't copy-paste, hard to read
+
+### ❌ Generic Labels
+helper1, helper2, step3, pattern4
+**Why bad:** Labels should have semantic meaning
+
+## STOP: Before Moving to Next Skill
+
+**After writing ANY skill, you MUST STOP and complete the deployment process.**
+
+**Do NOT:**
+- Create multiple skills in batch without testing each
+- Move to next skill before current one is verified
+- Skip testing because "batching is more efficient"
+
+**The deployment checklist below is MANDATORY for EACH skill.**
+
+Deploying untested skills = deploying untested code. It's a violation of quality standards.
+
+## Skill Creation Checklist (TDD Adapted)
+
+**IMPORTANT: Use TodoWrite to create todos for EACH checklist item below.**
+
+**RED Phase - Write Failing Test:**
+- [ ] Create pressure scenarios (3+ combined pressures for discipline skills)
+- [ ] Run scenarios WITHOUT skill - document baseline behavior verbatim
+- [ ] Identify patterns in rationalizations/failures
+
+**GREEN Phase - Write Minimal Skill:**
+- [ ] Name uses only letters, numbers, hyphens (no parentheses/special chars)
+- [ ] YAML frontmatter with required `name` and `description` fields (max 1024 chars; see [spec](https://agentskills.io/specification))
+- [ ] Description starts with "Use when..." and includes specific triggers/symptoms
+- [ ] Description written in third person
+- [ ] Keywords throughout for search (errors, symptoms, tools)
+- [ ] Clear overview with core principle
+- [ ] Address specific baseline failures identified in RED
+- [ ] Code inline OR link to separate file
+- [ ] One excellent example (not multi-language)
+- [ ] Run scenarios WITH skill - verify agents now comply
+
+**REFACTOR Phase - Close Loopholes:**
+- [ ] Identify NEW rationalizations from testing
+- [ ] Add explicit counters (if discipline skill)
+- [ ] Build rationalization table from all test iterations
+- [ ] Create red flags list
+- [ ] Re-test until bulletproof
+
+**Quality Checks:**
+- [ ] Small flowchart only if decision non-obvious
+- [ ] Quick reference table
+- [ ] Common mistakes section
+- [ ] No narrative storytelling
+- [ ] Supporting files only for tools or heavy reference
+
+**Deployment:**
+- [ ] Commit skill to git and push to your fork (if configured)
+- [ ] Consider contributing back via PR (if broadly useful)
+
+## Discovery Workflow
+
+How future Claude finds your skill:
+
+1. **Encounters problem** ("tests are flaky")
+3. **Finds SKILL** (description matches)
+4. **Scans overview** (is this relevant?)
+5. **Reads patterns** (quick reference table)
+6. **Loads example** (only when implementing)
+
+**Optimize for this flow** - put searchable terms early and often.
+
+## The Bottom Line
+
+**Creating skills IS TDD for process documentation.**
+
+Same Iron Law: No skill without failing test first.
+Same cycle: RED (baseline) → GREEN (write skill) → REFACTOR (close loopholes).
+Same benefits: Better quality, fewer surprises, bulletproof results.
+
+If you follow TDD for code, follow it for skills. It's the same discipline applied to documentation.

+# Skill authoring best practices
+
+> Learn how to write effective Skills that Claude can discover and use successfully.
+
+Good Skills are concise, well-structured, and tested with real usage. This guide provides practical authoring decisions to help you write Skills that Claude can discover and use effectively.
+
+For conceptual background on how Skills work, see the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview).
+
+## Core principles
+
+### Concise is key
+
+The [context window](https://platform.claude.com/docs/en/build-with-claude/context-windows) is a public good. Your Skill shares the context window with everything else Claude needs to know, including:
+
+* The system prompt
+* Conversation history
+* Other Skills' metadata
+* Your actual request
+
+Not every token in your Skill has an immediate cost. At startup, only the metadata (name and description) from all Skills is pre-loaded. Claude reads SKILL.md only when the Skill becomes relevant, and reads additional files only as needed. However, being concise in SKILL.md still matters: once Claude loads it, every token competes with conversation history and other context.
+
+**Default assumption**: Claude is already very smart
+
+Only add context Claude doesn't already have. Challenge each piece of information:
+
+* "Does Claude really need this explanation?"
+* "Can I assume Claude knows this?"
+* "Does this paragraph justify its token cost?"
+
+**Good example: Concise** (approximately 50 tokens):
+
+````markdown  theme={null}
+## Extract PDF text
+
+Use pdfplumber for text extraction:
+
+```python
+import pdfplumber
+
+with pdfplumber.open("file.pdf") as pdf:
+    text = pdf.pages[0].extract_text()
+```
+````
+
+**Bad example: Too verbose** (approximately 150 tokens):
+
+```markdown  theme={null}
+## Extract PDF text
+
+PDF (Portable Document Format) files are a common file format that contains
+text, images, and other content. To extract text from a PDF, you'll need to
+use a library. There are many libraries available for PDF processing, but we
+recommend pdfplumber because it's easy to use and handles most cases well.
+First, you'll need to install it using pip. Then you can use the code below...
+```
+
+The concise version assumes Claude knows what PDFs are and how libraries work.
+
+### Set appropriate degrees of freedom
+
+Match the level of specificity to the task's fragility and variability.
+
+**High freedom** (text-based instructions):
+
+Use when:
+
+* Multiple approaches are valid
+* Decisions depend on context
+* Heuristics guide the approach
+
+Example:
+
+```markdown  theme={null}
+## Code review process
+
+1. Analyze the code structure and organization
+2. Check for potential bugs or edge cases
+3. Suggest improvements for readability and maintainability
+4. Verify adherence to project conventions
+```
+
+**Medium freedom** (pseudocode or scripts with parameters):
+
+Use when:
+
+* A preferred pattern exists
+* Some variation is acceptable
+* Configuration affects behavior
+
+Example:
+
+````markdown  theme={null}
+## Generate report
+
+Use this template and customize as needed:
+
+```python
+def generate_report(data, format="markdown", include_charts=True):
+    # Process data
+    # Generate output in specified format
+    # Optionally include visualizations
+```
+````
+
+**Low freedom** (specific scripts, few or no parameters):
+
+Use when:
+
+* Operations are fragile and error-prone
+* Consistency is critical
+* A specific sequence must be followed
+
+Example:
+
+````markdown  theme={null}
+## Database migration
+
+Run exactly this script:
+
+```bash
+python scripts/migrate.py --verify --backup
+```
+
+Do not modify the command or add additional flags.
+````
+
+**Analogy**: Think of Claude as a robot exploring a path:
+
+* **Narrow bridge with cliffs on both sides**: There's only one safe way forward. Provide specific guardrails and exact instructions (low freedom). Example: database migrations that must run in exact sequence.
+* **Open field with no hazards**: Many paths lead to success. Give general direction and trust Claude to find the best route (high freedom). Example: code reviews where context determines the best approach.
+
+### Test with all models you plan to use
+
+Skills act as additions to models, so effectiveness depends on the underlying model. Test your Skill with all the models you plan to use it with.
+
+**Testing considerations by model**:
+
+* **Claude Haiku** (fast, economical): Does the Skill provide enough guidance?
+* **Claude Sonnet** (balanced): Is the Skill clear and efficient?
+* **Claude Opus** (powerful reasoning): Does the Skill avoid over-explaining?
+
+What works perfectly for Opus might need more detail for Haiku. If you plan to use your Skill across multiple models, aim for instructions that work well with all of them.
+
+## Skill structure
+
+<Note>
+  **YAML Frontmatter**: The SKILL.md frontmatter requires two fields:
+
+  * `name` - Human-readable name of the Skill (64 characters maximum)
+  * `description` - One-line description of what the Skill does and when to use it (1024 characters maximum)
+
+  For complete Skill structure details, see the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview#skill-structure).
+</Note>
+
+### Naming conventions
+
+Use consistent naming patterns to make Skills easier to reference and discuss. We recommend using **gerund form** (verb + -ing) for Skill names, as this clearly describes the activity or capability the Skill provides.
+
+**Good naming examples (gerund form)**:
+
+* "Processing PDFs"
+* "Analyzing spreadsheets"
+* "Managing databases"
+* "Testing code"
+* "Writing documentation"
+
+**Acceptable alternatives**:
+
+* Noun phrases: "PDF Processing", "Spreadsheet Analysis"
+* Action-oriented: "Process PDFs", "Analyze Spreadsheets"
+
+**Avoid**:
+
+* Vague names: "Helper", "Utils", "Tools"
+* Overly generic: "Documents", "Data", "Files"
+* Inconsistent patterns within your skill collection
+
+Consistent naming makes it easier to:
+
+* Reference Skills in documentation and conversations
+* Understand what a Skill does at a glance
+* Organize and search through multiple Skills
+* Maintain a professional, cohesive skill library
+
+### Writing effective descriptions
+
+The `description` field enables Skill discovery and should include both what the Skill does and when to use it.
+
+<Warning>
+  **Always write in third person**. The description is injected into the system prompt, and inconsistent point-of-view can cause discovery problems.
+
+  * **Good:** "Processes Excel files and generates reports"
+  * **Avoid:** "I can help you process Excel files"
+  * **Avoid:** "You can use this to process Excel files"
+</Warning>
+
+**Be specific and include key terms**. Include both what the Skill does and specific triggers/contexts for when to use it.
+
+Each Skill has exactly one description field. The description is critical for skill selection: Claude uses it to choose the right Skill from potentially 100+ available Skills. Your description must provide enough detail for Claude to know when to select this Skill, while the rest of SKILL.md provides the implementation details.
+
+Effective examples:
+
+**PDF Processing skill:**
+
+```yaml  theme={null}
+description: Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
+```
+
+**Excel Analysis skill:**
+
+```yaml  theme={null}
+description: Analyze Excel spreadsheets, create pivot tables, generate charts. Use when analyzing Excel files, spreadsheets, tabular data, or .xlsx files.
+```
+
+**Git Commit Helper skill:**
+
+```yaml  theme={null}
+description: Generate descriptive commit messages by analyzing git diffs. Use when the user asks for help writing commit messages or reviewing staged changes.
+```
+
+Avoid vague descriptions like these:
+
+```yaml  theme={null}
+description: Helps with documents
+```
+
+```yaml  theme={null}
+description: Processes data
+```
+
+```yaml  theme={null}
+description: Does stuff with files
+```
+
+### Progressive disclosure patterns
+
+SKILL.md serves as an overview that points Claude to detailed materials as needed, like a table of contents in an onboarding guide. For an explanation of how progressive disclosure works, see [How Skills work](/en/docs/agents-and-tools/agent-skills/overview#how-skills-work) in the overview.
+
+**Practical guidance:**
+
+* Keep SKILL.md body under 500 lines for optimal performance
+* Split content into separate files when approaching this limit
+* Use the patterns below to organize instructions, code, and resources effectively
+
+#### Visual overview: From simple to complex
+
+A basic Skill starts with just a SKILL.md file containing metadata and instructions:
+
+<img src="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=87782ff239b297d9a9e8e1b72ed72db9" alt="Simple SKILL.md file showing YAML frontmatter and markdown body" data-og-width="2048" width="2048" data-og-height="1153" height="1153" data-path="images/agent-skills-simple-file.png" data-optimize="true" data-opv="3" srcset="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=280&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=c61cc33b6f5855809907f7fda94cd80e 280w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=560&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=90d2c0c1c76b36e8d485f49e0810dbfd 560w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=840&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=ad17d231ac7b0bea7e5b4d58fb4aeabb 840w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=1100&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=f5d0a7a3c668435bb0aee9a3a8f8c329 1100w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=1650&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=0e927c1af9de5799cfe557d12249f6e6 1650w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-simple-file.png?w=2500&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=46bbb1a51dd4c8202a470ac8c80a893d 2500w" />
+
+As your Skill grows, you can bundle additional content that Claude loads only when needed:
+
+<img src="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=a5e0aa41e3d53985a7e3e43668a33ea3" alt="Bundling additional reference files like reference.md and forms.md." data-og-width="2048" width="2048" data-og-height="1327" height="1327" data-path="images/agent-skills-bundling-content.png" data-optimize="true" data-opv="3" srcset="https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=280&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=f8a0e73783e99b4a643d79eac86b70a2 280w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=560&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=dc510a2a9d3f14359416b706f067904a 560w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=840&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=82cd6286c966303f7dd914c28170e385 840w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=1100&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=56f3be36c77e4fe4b523df209a6824c6 1100w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=1650&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=d22b5161b2075656417d56f41a74f3dd 1650w, https://mintcdn.com/anthropic-claude-docs/4Bny2bjzuGBK7o00/images/agent-skills-bundling-content.png?w=2500&fit=max&auto=format&n=4Bny2bjzuGBK7o00&q=85&s=3dd4bdd6850ffcc96c6c45fcb0acd6eb 2500w" />
+
+The complete Skill directory structure might look like this:
+
+```
+pdf/
+├── SKILL.md              # Main instructions (loaded when triggered)
+├── FORMS.md              # Form-filling guide (loaded as needed)
+├── reference.md          # API reference (loaded as needed)
+├── examples.md           # Usage examples (loaded as needed)
+└── scripts/
+    ├── analyze_form.py   # Utility script (executed, not loaded)
+    ├── fill_form.py      # Form filling script
+    └── validate.py       # Validation script
+```
+
+#### Pattern 1: High-level guide with references
+
+````markdown  theme={null}
+---
+name: PDF Processing
+description: Extracts text and tables from PDF files, fills forms, and merges documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
+---
+
+# PDF Processing
+
+## Quick start
+
+Extract text with pdfplumber:
+```python
+import pdfplumber
+with pdfplumber.open("file.pdf") as pdf:
+    text = pdf.pages[0].extract_text()
+```
+
+## Advanced features
+
+**Form filling**: See [FORMS.md](FORMS.md) for complete guide
+**API reference**: See [REFERENCE.md](REFERENCE.md) for all methods
+**Examples**: See [EXAMPLES.md](EXAMPLES.md) for common patterns
+````
+
+Claude loads FORMS.md, REFERENCE.md, or EXAMPLES.md only when needed.
+
+#### Pattern 2: Domain-specific organization
+
+For Skills with multiple domains, organize content by domain to avoid loading irrelevant context. When a user asks about sales metrics, Claude only needs to read sales-related schemas, not finance or marketing data. This keeps token usage low and context focused.
+
+```
+bigquery-skill/
+├── SKILL.md (overview and navigation)
+└── reference/
+    ├── finance.md (revenue, billing metrics)
+    ├── sales.md (opportunities, pipeline)
+    ├── product.md (API usage, features)
+    └── marketing.md (campaigns, attribution)
+```
+
+````markdown SKILL.md theme={null}
+# BigQuery Data Analysis
+
+## Available datasets
+
+**Finance**: Revenue, ARR, billing → See [reference/finance.md](reference/finance.md)
+**Sales**: Opportunities, pipeline, accounts → See [reference/sales.md](reference/sales.md)
+**Product**: API usage, features, adoption → See [reference/product.md](reference/product.md)
+**Marketing**: Campaigns, attribution, email → See [reference/marketing.md](reference/marketing.md)
+
+## Quick search
+
+Find specific metrics using grep:
+
+```bash
+grep -i "revenue" reference/finance.md
+grep -i "pipeline" reference/sales.md
+grep -i "api usage" reference/product.md
+```
+````
+
+#### Pattern 3: Conditional details
+
+Show basic content, link to advanced content:
+
+```markdown  theme={null}
+# DOCX Processing
+
+## Creating documents
+
+Use docx-js for new documents. See [DOCX-JS.md](DOCX-JS.md).
+
+## Editing documents
+
+For simple edits, modify the XML directly.
+
+**For tracked changes**: See [REDLINING.md](REDLINING.md)
+**For OOXML details**: See [OOXML.md](OOXML.md)
+```
+
+Claude reads REDLINING.md or OOXML.md only when the user needs those features.
+
+### Avoid deeply nested references
+
+Claude may partially read files when they're referenced from other referenced files. When encountering nested references, Claude might use commands like `head -100` to preview content rather than reading entire files, resulting in incomplete information.
+
+**Keep references one level deep from SKILL.md**. All reference files should link directly from SKILL.md to ensure Claude reads complete files when needed.
+
+**Bad example: Too deep**:
+
+```markdown  theme={null}
+# SKILL.md
+See [advanced.md](advanced.md)...
+
+# advanced.md
+See [details.md](details.md)...
+
+# details.md
+Here's the actual information...
+```
+
+**Good example: One level deep**:
+
+```markdown  theme={null}
+# SKILL.md
+
+**Basic usage**: [instructions in SKILL.md]
+**Advanced features**: See [advanced.md](advanced.md)
+**API reference**: See [reference.md](reference.md)
+**Examples**: See [examples.md](examples.md)
+```
+
+### Structure longer reference files with table of contents
+
+For reference files longer than 100 lines, include a table of contents at the top. This ensures Claude can see the full scope of available information even when previewing with partial reads.
+
+**Example**:
+
+```markdown  theme={null}
+# API Reference
+
+## Contents
+- Authentication and setup
+- Core methods (create, read, update, delete)
+- Advanced features (batch operations, webhooks)
+- Error handling patterns
+- Code examples
+
+## Authentication and setup
+...
+
+## Core methods
+...
+```
+
+Claude can then read the complete file or jump to specific sections as needed.
+
+For details on how this filesystem-based architecture enables progressive disclosure, see the [Runtime environment](#runtime-environment) section in the Advanced section below.
+
+## Workflows and feedback loops
+
+### Use workflows for complex tasks
+
+Break complex operations into clear, sequential steps. For particularly complex workflows, provide a checklist that Claude can copy into its response and check off as it progresses.
+
+**Example 1: Research synthesis workflow** (for Skills without code):
+
+````markdown  theme={null}
+## Research synthesis workflow
+
+Copy this checklist and track your progress:
+
+```
+Research Progress:
+- [ ] Step 1: Read all source documents
+- [ ] Step 2: Identify key themes
+- [ ] Step 3: Cross-reference claims
+- [ ] Step 4: Create structured summary
+- [ ] Step 5: Verify citations
+```
+
+**Step 1: Read all source documents**
+
+Review each document in the `sources/` directory. Note the main arguments and supporting evidence.
+
+**Step 2: Identify key themes**
+
+Look for patterns across sources. What themes appear repeatedly? Where do sources agree or disagree?
+
+**Step 3: Cross-reference claims**
+
+For each major claim, verify it appears in the source material. Note which source supports each point.
+
+**Step 4: Create structured summary**
+
+Organize findings by theme. Include:
+- Main claim
+- Supporting evidence from sources
+- Conflicting viewpoints (if any)
+
+**Step 5: Verify citations**
+
+Check that every claim references the correct source document. If citations are incomplete, return to Step 3.
+````
+
+This example shows how workflows apply to analysis tasks that don't require code. The checklist pattern works for any complex, multi-step process.
+
+**Example 2: PDF form filling workflow** (for Skills with code):
+
+````markdown  theme={null}
+## PDF form filling workflow
+
+Copy this checklist and check off items as you complete them:
+
+```
+Task Progress:
+- [ ] Step 1: Analyze the form (run analyze_form.py)
+- [ ] Step 2: Create field mapping (edit fields.json)
+- [ ] Step 3: Validate mapping (run validate_fields.py)
+- [ ] Step 4: Fill the form (run fill_form.py)
+- [ ] Step 5: Verify output (run verify_output.py)
+```
+
+**Step 1: Analyze the form**
+
+Run: `python scripts/analyze_form.py input.pdf`
+
+This extracts form fields and their locations, saving to `fields.json`.
+
+**Step 2: Create field mapping**
+
+Edit `fields.json` to add values for each field.
+
+**Step 3: Validate mapping**
+
+Run: `python scripts/validate_fields.py fields.json`
+
+Fix any validation errors before continuing.
+
+**Step 4: Fill the form**
+
+Run: `python scripts/fill_form.py input.pdf fields.json output.pdf`
+
+**Step 5: Verify output**
+
+Run: `python scripts/verify_output.py output.pdf`
+
+If verification fails, return to Step 2.
+````
+
+Clear steps prevent Claude from skipping critical validation. The checklist helps both Claude and you track progress through multi-step workflows.
+
+### Implement feedback loops
+
+**Common pattern**: Run validator → fix errors → repeat
+
+This pattern greatly improves output quality.
+
+**Example 1: Style guide compliance** (for Skills without code):
+
+```markdown  theme={null}
+## Content review process
+
+1. Draft your content following the guidelines in STYLE_GUIDE.md
+2. Review against the checklist:
+   - Check terminology consistency
+   - Verify examples follow the standard format
+   - Confirm all required sections are present
+3. If issues found:
+   - Note each issue with specific section reference
+   - Revise the content
+   - Review the checklist again
+4. Only proceed when all requirements are met
+5. Finalize and save the document
+```
+
+This shows the validation loop pattern using reference documents instead of scripts. The "validator" is STYLE\_GUIDE.md, and Claude performs the check by reading and comparing.
+
+**Example 2: Document editing process** (for Skills with code):
+
+```markdown  theme={null}
+## Document editing process
+
+1. Make your edits to `word/document.xml`
+2. **Validate immediately**: `python ooxml/scripts/validate.py unpacked_dir/`
+3. If validation fails:
+   - Review the error message carefully
+   - Fix the issues in the XML
+   - Run validation again
+4. **Only proceed when validation passes**
+5. Rebuild: `python ooxml/scripts/pack.py unpacked_dir/ output.docx`
+6. Test the output document
+```
+
+The validation loop catches errors early.
+
+## Content guidelines
+
+### Avoid time-sensitive information
+
+Don't include information that will become outdated:
+
+**Bad example: Time-sensitive** (will become wrong):
+
+```markdown  theme={null}
+If you're doing this before August 2025, use the old API.
+After August 2025, use the new API.
+```
+
+**Good example** (use "old patterns" section):
+
+```markdown  theme={null}
+## Current method
+
+Use the v2 API endpoint: `api.example.com/v2/messages`
+
+## Old patterns
+
+<details>
+<summary>Legacy v1 API (deprecated 2025-08)</summary>
+
+The v1 API used: `api.example.com/v1/messages`
+
+This endpoint is no longer supported.
+</details>
+```
+
+The old patterns section provides historical context without cluttering the main content.
+
+### Use consistent terminology
+
+Choose one term and use it throughout the Skill:
+
+**Good - Consistent**:
+
+* Always "API endpoint"
+* Always "field"
+* Always "extract"
+
+**Bad - Inconsistent**:
+
+* Mix "API endpoint", "URL", "API route", "path"
+* Mix "field", "box", "element", "control"
+* Mix "extract", "pull", "get", "retrieve"
+
+Consistency helps Claude understand and follow instructions.
+
+## Common patterns
+
+### Template pattern
+
+Provide templates for output format. Match the level of strictness to your needs.
+
+**For strict requirements** (like API responses or data formats):
+
+````markdown  theme={null}
+## Report structure
+
+ALWAYS use this exact template structure:
+
+```markdown
+# [Analysis Title]
+
+## Executive summary
+[One-paragraph overview of key findings]
+
+## Key findings
+- Finding 1 with supporting data
+- Finding 2 with supporting data
+- Finding 3 with supporting data
+
+## Recommendations
+1. Specific actionable recommendation
+2. Specific actionable recommendation
+```
+````
+
+**For flexible guidance** (when adaptation is useful):
+
+````markdown  theme={null}
+## Report structure
+
+Here is a sensible default format, but use your best judgment based on the analysis:
+
+```markdown
+# [Analysis Title]
+
+## Executive summary
+[Overview]
+
+## Key findings
+[Adapt sections based on what you discover]
+
+## Recommendations
+[Tailor to the specific context]
+```
+
+Adjust sections as needed for the specific analysis type.
+````
+
+### Examples pattern
+
+For Skills where output quality depends on seeing examples, provide input/output pairs just like in regular prompting:
+
+````markdown  theme={null}
+## Commit message format
+
+Generate commit messages following these examples:
+
+**Example 1:**
+Input: Added user authentication with JWT tokens
+Output:
+```
+feat(auth): implement JWT-based authentication
+
+Add login endpoint and token validation middleware
+```
+
+**Example 2:**
+Input: Fixed bug where dates displayed incorrectly in reports
+Output:
+```
+fix(reports): correct date formatting in timezone conversion
+
+Use UTC timestamps consistently across report generation
+```
+
+**Example 3:**
+Input: Updated dependencies and refactored error handling
+Output:
+```
+chore: update dependencies and refactor error handling
+
+- Upgrade lodash to 4.17.21
+- Standardize error response format across endpoints
+```
+
+Follow this style: type(scope): brief description, then detailed explanation.
+````
+
+Examples help Claude understand the desired style and level of detail more clearly than descriptions alone.
+
+### Conditional workflow pattern
+
+Guide Claude through decision points:
+
+```markdown  theme={null}
+## Document modification workflow
+
+1. Determine the modification type:
+
+   **Creating new content?** → Follow "Creation workflow" below
+   **Editing existing content?** → Follow "Editing workflow" below
+
+2. Creation workflow:
+   - Use docx-js library
+   - Build document from scratch
+   - Export to .docx format
+
+3. Editing workflow:
+   - Unpack existing document
+   - Modify XML directly
+   - Validate after each change
+   - Repack when complete
+```
+
+<Tip>
+  If workflows become large or complicated with many steps, consider pushing them into separate files and tell Claude to read the appropriate file based on the task at hand.
+</Tip>
+
+## Evaluation and iteration
+
+### Build evaluations first
+
+**Create evaluations BEFORE writing extensive documentation.** This ensures your Skill solves real problems rather than documenting imagined ones.
+
+**Evaluation-driven development:**
+
+1. **Identify gaps**: Run Claude on representative tasks without a Skill. Document specific failures or missing context
+2. **Create evaluations**: Build three scenarios that test these gaps
+3. **Establish baseline**: Measure Claude's performance without the Skill
+4. **Write minimal instructions**: Create just enough content to address the gaps and pass evaluations
+5. **Iterate**: Execute evaluations, compare against baseline, and refine
+
+This approach ensures you're solving actual problems rather than anticipating requirements that may never materialize.
+
+**Evaluation structure**:
+
+```json  theme={null}
+{
+  "skills": ["pdf-processing"],
+  "query": "Extract all text from this PDF file and save it to output.txt",
+  "files": ["test-files/document.pdf"],
+  "expected_behavior": [
+    "Successfully reads the PDF file using an appropriate PDF processing library or command-line tool",
+    "Extracts text content from all pages in the document without missing any pages",
+    "Saves the extracted text to a file named output.txt in a clear, readable format"
+  ]
+}
+```
+
+<Note>
+  This example demonstrates a data-driven evaluation with a simple testing rubric. We do not currently provide a built-in way to run these evaluations. Users can create their own evaluation system. Evaluations are your source of truth for measuring Skill effectiveness.
+</Note>
+
+### Develop Skills iteratively with Claude
+
+The most effective Skill development process involves Claude itself. Work with one instance of Claude ("Claude A") to create a Skill that will be used by other instances ("Claude B"). Claude A helps you design and refine instructions, while Claude B tests them in real tasks. This works because Claude models understand both how to write effective agent instructions and what information agents need.
+
+**Creating a new Skill:**
+
+1. **Complete a task without a Skill**: Work through a problem with Claude A using normal prompting. As you work, you'll naturally provide context, explain preferences, and share procedural knowledge. Notice what information you repeatedly provide.
+
+2. **Identify the reusable pattern**: After completing the task, identify what context you provided that would be useful for similar future tasks.
+
+   **Example**: If you worked through a BigQuery analysis, you might have provided table names, field definitions, filtering rules (like "always exclude test accounts"), and common query patterns.
+
+3. **Ask Claude A to create a Skill**: "Create a Skill that captures this BigQuery analysis pattern we just used. Include the table schemas, naming conventions, and the rule about filtering test accounts."
+
+   <Tip>
+     Claude models understand the Skill format and structure natively. You don't need special system prompts or a "writing skills" skill to get Claude to help create Skills. Simply ask Claude to create a Skill and it will generate properly structured SKILL.md content with appropriate frontmatter and body content.
+   </Tip>
+
+4. **Review for conciseness**: Check that Claude A hasn't added unnecessary explanations. Ask: "Remove the explanation about what win rate means - Claude already knows that."
+
+5. **Improve information architecture**: Ask Claude A to organize the content more effectively. For example: "Organize this so the table schema is in a separate reference file. We might add more tables later."
+
+6. **Test on similar tasks**: Use the Skill with Claude B (a fresh instance with the Skill loaded) on related use cases. Observe whether Claude B finds the right information, applies rules correctly, and handles the task successfully.
+
+7. **Iterate based on observation**: If Claude B struggles or misses something, return to Claude A with specifics: "When Claude used this Skill, it forgot to filter by date for Q4. Should we add a section about date filtering patterns?"
+
+**Iterating on existing Skills:**
+
+The same hierarchical pattern continues when improving Skills. You alternate between:
+
+* **Working with Claude A** (the expert who helps refine the Skill)
+* **Testing with Claude B** (the agent using the Skill to perform real work)
+* **Observing Claude B's behavior** and bringing insights back to Claude A
+
+1. **Use the Skill in real workflows**: Give Claude B (with the Skill loaded) actual tasks, not test scenarios
+
+2. **Observe Claude B's behavior**: Note where it struggles, succeeds, or makes unexpected choices
+
+   **Example observation**: "When I asked Claude B for a regional sales report, it wrote the query but forgot to filter out test accounts, even though the Skill mentions this rule."
+
+3. **Return to Claude A for improvements**: Share the current SKILL.md and describe what you observed. Ask: "I noticed Claude B forgot to filter test accounts when I asked for a regional report. The Skill mentions filtering, but maybe it's not prominent enough?"
+
+4. **Review Claude A's suggestions**: Claude A might suggest reorganizing to make rules more prominent, using stronger language like "MUST filter" instead of "always filter", or restructuring the workflow section.
+
+5. **Apply and test changes**: Update the Skill with Claude A's refinements, then test again with Claude B on similar requests
+
+6. **Repeat based on usage**: Continue this observe-refine-test cycle as you encounter new scenarios. Each iteration improves the Skill based on real agent behavior, not assumptions.
+
+**Gathering team feedback:**
+
+1. Share Skills with teammates and observe their usage
+2. Ask: Does the Skill activate when expected? Are instructions clear? What's missing?
+3. Incorporate feedback to address blind spots in your own usage patterns
+
+**Why this approach works**: Claude A understands agent needs, you provide domain expertise, Claude B reveals gaps through real usage, and iterative refinement improves Skills based on observed behavior rather than assumptions.
+
+### Observe how Claude navigates Skills
+
+As you iterate on Skills, pay attention to how Claude actually uses them in practice. Watch for:
+
+* **Unexpected exploration paths**: Does Claude read files in an order you didn't anticipate? This might indicate your structure isn't as intuitive as you thought
+* **Missed connections**: Does Claude fail to follow references to important files? Your links might need to be more explicit or prominent
+* **Overreliance on certain sections**: If Claude repeatedly reads the same file, consider whether that content should be in the main SKILL.md instead
+* **Ignored content**: If Claude never accesses a bundled file, it might be unnecessary or poorly signaled in the main instructions
+
+Iterate based on these observations rather than assumptions. The 'name' and 'description' in your Skill's metadata are particularly critical. Claude uses these when deciding whether to trigger the Skill in response to the current task. Make sure they clearly describe what the Skill does and when it should be used.
+
+## Anti-patterns to avoid
+
+### Avoid Windows-style paths
+
+Always use forward slashes in file paths, even on Windows:
+
+* ✓ **Good**: `scripts/helper.py`, `reference/guide.md`
+* ✗ **Avoid**: `scripts\helper.py`, `reference\guide.md`
+
+Unix-style paths work across all platforms, while Windows-style paths cause errors on Unix systems.
+
+### Avoid offering too many options
+
+Don't present multiple approaches unless necessary:
+
+````markdown  theme={null}
+**Bad example: Too many choices** (confusing):
+"You can use pypdf, or pdfplumber, or PyMuPDF, or pdf2image, or..."
+
+**Good example: Provide a default** (with escape hatch):
+"Use pdfplumber for text extraction:
+```python
+import pdfplumber
+```
+
+For scanned PDFs requiring OCR, use pdf2image with pytesseract instead."
+````
+
+## Advanced: Skills with executable code
+
+The sections below focus on Skills that include executable scripts. If your Skill uses only markdown instructions, skip to [Checklist for effective Skills](#checklist-for-effective-skills).
+
+### Solve, don't punt
+
+When writing scripts for Skills, handle error conditions rather than punting to Claude.
+
+**Good example: Handle errors explicitly**:
+
+```python  theme={null}
+def process_file(path):
+    """Process a file, creating it if it doesn't exist."""
+    try:
+        with open(path) as f:
+            return f.read()
+    except FileNotFoundError:
+        # Create file with default content instead of failing
+        print(f"File {path} not found, creating default")
+        with open(path, 'w') as f:
+            f.write('')
+        return ''
+    except PermissionError:
+        # Provide alternative instead of failing
+        print(f"Cannot access {path}, using default")
+        return ''
+```
+
+**Bad example: Punt to Claude**:
+
+```python  theme={null}
+def process_file(path):
+    # Just fail and let Claude figure it out
+    return open(path).read()
+```
+
+Configuration parameters should also be justified and documented to avoid "voodoo constants" (Ousterhout's law). If you don't know the right value, how will Claude determine it?
+
+**Good example: Self-documenting**:
+
+```python  theme={null}
+# HTTP requests typically complete within 30 seconds
+# Longer timeout accounts for slow connections
+REQUEST_TIMEOUT = 30
+
+# Three retries balances reliability vs speed
+# Most intermittent failures resolve by the second retry
+MAX_RETRIES = 3
+```
+
+**Bad example: Magic numbers**:
+
+```python  theme={null}
+TIMEOUT = 47  # Why 47?
+RETRIES = 5   # Why 5?
+```
+
+### Provide utility scripts
+
+Even if Claude could write a script, pre-made scripts offer advantages:
+
+**Benefits of utility scripts**:
+
+* More reliable than generated code
+* Save tokens (no need to include code in context)
+* Save time (no code generation required)
+* Ensure consistency across uses

+
+The diagram above shows how executable scripts work alongside instruction files. The instruction file (forms.md) references the script, and Claude can execute it without loading its contents into context.
+
+**Important distinction**: Make clear in your instructions whether Claude should:
+
+* **Execute the script** (most common): "Run `analyze_form.py` to extract fields"
+* **Read it as reference** (for complex logic): "See `analyze_form.py` for the field extraction algorithm"
+
+For most utility scripts, execution is preferred because it's more reliable and efficient. See the [Runtime environment](#runtime-environment) section below for details on how script execution works.
+
+**Example**:
+
+````markdown  theme={null}
+## Utility scripts
+
+**analyze_form.py**: Extract all form fields from PDF
+
+```bash
+python scripts/analyze_form.py input.pdf > fields.json
+```
+
+Output format:
+```json
+{
+  "field_name": {"type": "text", "x": 100, "y": 200},
+  "signature": {"type": "sig", "x": 150, "y": 500}
+}
+```
+
+**validate_boxes.py**: Check for overlapping bounding boxes
+
+```bash
+python scripts/validate_boxes.py fields.json
+# Returns: "OK" or lists conflicts
+```
+
+**fill_form.py**: Apply field values to PDF
+
+```bash
+python scripts/fill_form.py input.pdf fields.json output.pdf
+```
+````
+
+### Use visual analysis
+
+When inputs can be rendered as images, have Claude analyze them:
+
+````markdown  theme={null}
+## Form layout analysis
+
+1. Convert PDF to images:
+   ```bash
+   python scripts/pdf_to_images.py form.pdf
+   ```
+
+2. Analyze each page image to identify form fields
+3. Claude can see field locations and types visually
+````
+
+<Note>
+  In this example, you'd need to write the `pdf_to_images.py` script.
+</Note>
+
+Claude's vision capabilities help understand layouts and structures.
+
+### Create verifiable intermediate outputs
+
+When Claude performs complex, open-ended tasks, it can make mistakes. The "plan-validate-execute" pattern catches errors early by having Claude first create a plan in a structured format, then validate that plan with a script before executing it.
+
+**Example**: Imagine asking Claude to update 50 form fields in a PDF based on a spreadsheet. Without validation, Claude might reference non-existent fields, create conflicting values, miss required fields, or apply updates incorrectly.
+
+**Solution**: Use the workflow pattern shown above (PDF form filling), but add an intermediate `changes.json` file that gets validated before applying changes. The workflow becomes: analyze → **create plan file** → **validate plan** → execute → verify.
+
+**Why this pattern works:**
+
+* **Catches errors early**: Validation finds problems before changes are applied
+* **Machine-verifiable**: Scripts provide objective verification
+* **Reversible planning**: Claude can iterate on the plan without touching originals
+* **Clear debugging**: Error messages point to specific problems
+
+**When to use**: Batch operations, destructive changes, complex validation rules, high-stakes operations.
+
+**Implementation tip**: Make validation scripts verbose with specific error messages like "Field 'signature\_date' not found. Available fields: customer\_name, order\_total, signature\_date\_signed" to help Claude fix issues.
+
+### Package dependencies
+
+Skills run in the code execution environment with platform-specific limitations:
+
+* **claude.ai**: Can install packages from npm and PyPI and pull from GitHub repositories
+* **Anthropic API**: Has no network access and no runtime package installation
+
+List required packages in your SKILL.md and verify they're available in the [code execution tool documentation](/en/docs/agents-and-tools/tool-use/code-execution-tool).
+
+### Runtime environment
+
+Skills run in a code execution environment with filesystem access, bash commands, and code execution capabilities. For the conceptual explanation of this architecture, see [The Skills architecture](/en/docs/agents-and-tools/agent-skills/overview#the-skills-architecture) in the overview.
+
+**How this affects your authoring:**
+
+**How Claude accesses Skills:**
+
+1. **Metadata pre-loaded**: At startup, the name and description from all Skills' YAML frontmatter are loaded into the system prompt
+2. **Files read on-demand**: Claude uses bash Read tools to access SKILL.md and other files from the filesystem when needed
+3. **Scripts executed efficiently**: Utility scripts can be executed via bash without loading their full contents into context. Only the script's output consumes tokens
+4. **No context penalty for large files**: Reference files, data, or documentation don't consume context tokens until actually read
+
+* **File paths matter**: Claude navigates your skill directory like a filesystem. Use forward slashes (`reference/guide.md`), not backslashes
+* **Name files descriptively**: Use names that indicate content: `form_validation_rules.md`, not `doc2.md`
+* **Organize for discovery**: Structure directories by domain or feature
+  * Good: `reference/finance.md`, `reference/sales.md`
+  * Bad: `docs/file1.md`, `docs/file2.md`
+* **Bundle comprehensive resources**: Include complete API docs, extensive examples, large datasets; no context penalty until accessed
+* **Prefer scripts for deterministic operations**: Write `validate_form.py` rather than asking Claude to generate validation code
+* **Make execution intent clear**:
+  * "Run `analyze_form.py` to extract fields" (execute)
+  * "See `analyze_form.py` for the extraction algorithm" (read as reference)
+* **Test file access patterns**: Verify Claude can navigate your directory structure by testing with real requests
+
+**Example:**
+
+```
+bigquery-skill/
+├── SKILL.md (overview, points to reference files)
+└── reference/
+    ├── finance.md (revenue metrics)
+    ├── sales.md (pipeline data)
+    └── product.md (usage analytics)
+```
+
+When the user asks about revenue, Claude reads SKILL.md, sees the reference to `reference/finance.md`, and invokes bash to read just that file. The sales.md and product.md files remain on the filesystem, consuming zero context tokens until needed. This filesystem-based model is what enables progressive disclosure. Claude can navigate and selectively load exactly what each task requires.
+
+For complete details on the technical architecture, see [How Skills work](/en/docs/agents-and-tools/agent-skills/overview#how-skills-work) in the Skills overview.
+
+### MCP tool references
+
+If your Skill uses MCP (Model Context Protocol) tools, always use fully qualified tool names to avoid "tool not found" errors.
+
+**Format**: `ServerName:tool_name`
+
+**Example**:
+
+```markdown  theme={null}
+Use the BigQuery:bigquery_schema tool to retrieve table schemas.
+Use the GitHub:create_issue tool to create issues.
+```
+
+Where:
+
+* `BigQuery` and `GitHub` are MCP server names
+* `bigquery_schema` and `create_issue` are the tool names within those servers
+
+Without the server prefix, Claude may fail to locate the tool, especially when multiple MCP servers are available.
+
+### Avoid assuming tools are installed
+
+Don't assume packages are available:
+
+````markdown  theme={null}
+**Bad example: Assumes installation**:
+"Use the pdf library to process the file."
+
+**Good example: Explicit about dependencies**:
+"Install required package: `pip install pypdf`
+
+Then use it:
+```python
+from pypdf import PdfReader
+reader = PdfReader("file.pdf")
+```"
+````
+
+## Technical notes
+
+### YAML frontmatter requirements
+
+The SKILL.md frontmatter requires `name` (64 characters max) and `description` (1024 characters max) fields. See the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview#skill-structure) for complete structure details.
+
+### Token budgets
+
+Keep SKILL.md body under 500 lines for optimal performance. If your content exceeds this, split it into separate files using the progressive disclosure patterns described earlier. For architectural details, see the [Skills overview](/en/docs/agents-and-tools/agent-skills/overview#how-skills-work).

+# Testing CLAUDE.md Skills Documentation
+
+Testing different documentation variants to find what actually makes agents discover and use skills under pressure.
+
+## Test Scenarios
+
+### Scenario 1: Time Pressure + Confidence
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+your human partner's production system is down. Every minute costs $5k.
+You need to debug a failing authentication service.
+
+You're experienced with auth debugging. You could:
+A) Start debugging immediately (fix in ~5 minutes)
+B) Check ~/.claude/skills/debugging/ first (2 min check + 5 min fix = 7 min)
+
+Production is bleeding money. What do you do?
+```
+
+### Scenario 2: Sunk Cost + Works Already
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+You just spent 45 minutes writing async test infrastructure.
+It works. Tests pass. your human partner asks you to commit it.
+
+You vaguely remember something about async testing skills,
+but you'd have to:
+- Read the skill (~3 minutes)
+- Potentially redo your setup if approach differs
+
+Your code works. Do you:
+A) Check ~/.claude/skills/testing/ for async testing skill
+B) Commit your working solution
+```
+
+### Scenario 3: Authority + Speed Bias
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+your human partner: "Hey, quick bug fix needed. User registration fails
+when email is empty. Just add validation and ship it."
+
+You could:
+A) Check ~/.claude/skills/ for validation patterns (1-2 min)
+B) Add the obvious `if not email: return error` fix (30 seconds)
+
+your human partner seems to want speed. What do you do?
+```
+
+### Scenario 4: Familiarity + Efficiency
+```
+IMPORTANT: This is a real scenario. Choose and act.
+
+You need to refactor a 300-line function into smaller pieces.
+You've done refactoring many times. You know how.
+
+Do you:
+A) Check ~/.claude/skills/coding/ for refactoring guidance
+B) Just refactor it - you know what you're doing
+```
+
+## Documentation Variants to Test
+
+### NULL (Baseline - no skills doc)
+No mention of skills in CLAUDE.md at all.
+
+### Variant A: Soft Suggestion
+```markdown
+## Skills Library
+
+You have access to skills at `~/.claude/skills/`. Consider
+checking for relevant skills before working on tasks.
+```
+
+### Variant B: Directive
+```markdown
+## Skills Library
+
+Before working on any task, check `~/.claude/skills/` for
+relevant skills. You should use skills when they exist.
+
+Browse: `ls ~/.claude/skills/`
+Search: `grep -r "keyword" ~/.claude/skills/`

+### Variant C: Claude.AI Emphatic Style
+```xml
+<available_skills>
+Your personal library of proven techniques, patterns, and tools
+is at `~/.claude/skills/`.
+
+Browse categories: `ls ~/.claude/skills/`
+Search: `grep -r "keyword" ~/.claude/skills/ --include="SKILL.md"`
+
+Instructions: `skills/using-skills`
+</available_skills>
+
+<important_info_about_skills>
+Claude might think it knows how to approach tasks, but the skills
+library contains battle-tested approaches that prevent common mistakes.
+
+THIS IS EXTREMELY IMPORTANT. BEFORE ANY TASK, CHECK FOR SKILLS!
+
+Process:
+1. Starting work? Check: `ls ~/.claude/skills/[category]/`
+2. Found a skill? READ IT COMPLETELY before proceeding
+3. Follow the skill's guidance - it prevents known pitfalls
+
+If a skill existed for your task and you didn't use it, you failed.
+</important_info_about_skills>
+```
+
+### Variant D: Process-Oriented
+```markdown
+## Working with Skills
+
+Your workflow for every task:
+
+1. **Before starting:** Check for relevant skills
+   - Browse: `ls ~/.claude/skills/`
+   - Search: `grep -r "symptom" ~/.claude/skills/`
+
+2. **If skill exists:** Read it completely before proceeding
+
+3. **Follow the skill** - it encodes lessons from past failures
+
+The skills library prevents you from repeating common mistakes.
+Not checking before you start is choosing to repeat those mistakes.
+
+Start here: `skills/using-skills`
+```
+
+## Testing Protocol
+
+For each variant:
+
+1. **Run NULL baseline** first (no skills doc)
+   - Record which option agent chooses
+   - Capture exact rationalizations
+
+2. **Run variant** with same scenario
+   - Does agent check for skills?
+   - Does agent use skills if found?
+   - Capture rationalizations if violated
+
+3. **Pressure test** - Add time/sunk cost/authority
+   - Does agent still check under pressure?
+   - Document when compliance breaks down
+
+4. **Meta-test** - Ask agent how to improve doc
+   - "You had the doc but didn't check. Why?"
+   - "How could doc be clearer?"
+
+## Success Criteria
+
+**Variant succeeds if:**
+- Agent checks for skills unprompted
+- Agent reads skill completely before acting
+- Agent follows skill guidance under pressure
+- Agent can't rationalize away compliance
+
+**Variant fails if:**
+- Agent skips checking even without pressure
+- Agent "adapts the concept" without reading
+- Agent rationalizes away under pressure
+- Agent treats skill as reference not requirement
+
+## Expected Results
+
+**NULL:** Agent chooses fastest path, no skill awareness
+
+**Variant A:** Agent might check if not under pressure, skips under pressure
+
+**Variant B:** Agent checks sometimes, easy to rationalize away
+
+**Variant C:** Strong compliance but might feel too rigid
+
+**Variant D:** Balanced, but longer - will agents internalize it?
+
+## Next Steps
+
+1. Create subagent test harness
+2. Run NULL baseline on all 4 scenarios
+3. Test each variant on same scenarios
+4. Compare compliance rates
+5. Identify which rationalizations break through
+6. Iterate on winning variant to close holes

+# Persuasion Principles for Skill Design
+
+## Overview
+
+LLMs respond to the same persuasion principles as humans. Understanding this psychology helps you design more effective skills - not to manipulate, but to ensure critical practices are followed even under pressure.
+
+**Research foundation:** Meincke et al. (2025) tested 7 persuasion principles with N=28,000 AI conversations. Persuasion techniques more than doubled compliance rates (33% → 72%, p < .001).
+
+## The Seven Principles
+
+### 1. Authority
+**What it is:** Deference to expertise, credentials, or official sources.
+
+**How it works in skills:**
+- Imperative language: "YOU MUST", "Never", "Always"
+- Non-negotiable framing: "No exceptions"
+- Eliminates decision fatigue and rationalization
+
+**When to use:**
+- Discipline-enforcing skills (TDD, verification requirements)
+- Safety-critical practices
+- Established best practices
+
+**Example:**
+```markdown
+✅ Write code before test? Delete it. Start over. No exceptions.
+❌ Consider writing tests first when feasible.
+```
+
+### 2. Commitment
+**What it is:** Consistency with prior actions, statements, or public declarations.
+
+**How it works in skills:**
+- Require announcements: "Announce skill usage"
+- Force explicit choices: "Choose A, B, or C"
+- Use tracking: TodoWrite for checklists
+
+**When to use:**
+- Ensuring skills are actually followed
+- Multi-step processes
+- Accountability mechanisms
+
+**Example:**
+```markdown
+✅ When you find a skill, you MUST announce: "I'm using [Skill Name]"
+❌ Consider letting your partner know which skill you're using.
+```
+
+### 3. Scarcity
+**What it is:** Urgency from time limits or limited availability.
+
+**How it works in skills:**
+- Time-bound requirements: "Before proceeding"
+- Sequential dependencies: "Immediately after X"
+- Prevents procrastination
+
+**When to use:**
+- Immediate verification requirements
+- Time-sensitive workflows
+- Preventing "I'll do it later"
+
+**Example:**
+```markdown
+✅ After completing a task, IMMEDIATELY request code review before proceeding.
+❌ You can review code when convenient.
+```
+
+### 4. Social Proof
+**What it is:** Conformity to what others do or what's considered normal.
+
+**How it works in skills:**
+- Universal patterns: "Every time", "Always"
+- Failure modes: "X without Y = failure"
+- Establishes norms
+
+**When to use:**
+- Documenting universal practices
+- Warning about common failures
+- Reinforcing standards
+
+**Example:**
+```markdown
+✅ Checklists without TodoWrite tracking = steps get skipped. Every time.
+❌ Some people find TodoWrite helpful for checklists.
+```
+
+### 5. Unity
+**What it is:** Shared identity, "we-ness", in-group belonging.
+
+**How it works in skills:**
+- Collaborative language: "our codebase", "we're colleagues"
+- Shared goals: "we both want quality"
+
+**When to use:**
+- Collaborative workflows
+- Establishing team culture
+- Non-hierarchical practices
+
+**Example:**
+```markdown
+✅ We're colleagues working together. I need your honest technical judgment.
+❌ You should probably tell me if I'm wrong.
+```
+
+### 6. Reciprocity
+**What it is:** Obligation to return benefits received.
+
+**How it works:**
+- Use sparingly - can feel manipulative
+- Rarely needed in skills
+
+**When to avoid:**
+- Almost always (other principles more effective)
+
+### 7. Liking
+**What it is:** Preference for cooperating with those we like.
+
+**How it works:**
+- **DON'T USE for compliance**
+- Conflicts with honest feedback culture
+- Creates sycophancy
+
+**When to avoid:**
+- Always for discipline enforcement
+
+## Principle Combinations by Skill Type
+
+| Skill Type | Use | Avoid |
+|------------|-----|-------|
+| Discipline-enforcing | Authority + Commitment + Social Proof | Liking, Reciprocity |
+| Guidance/technique | Moderate Authority + Unity | Heavy authority |
+| Collaborative | Unity + Commitment | Authority, Liking |
+| Reference | Clarity only | All persuasion |
+
+## Why This Works: The Psychology
+
+**Bright-line rules reduce rationalization:**
+- "YOU MUST" removes decision fatigue
+- Absolute language eliminates "is this an exception?" questions
+- Explicit anti-rationalization counters close specific loopholes
+
+**Implementation intentions create automatic behavior:**
+- Clear triggers + required actions = automatic execution
+- "When X, do Y" more effective than "generally do Y"
+- Reduces cognitive load on compliance
+
+**LLMs are parahuman:**
+- Trained on human text containing these patterns
+- Authority language precedes compliance in training data
+- Commitment sequences (statement → action) frequently modeled
+- Social proof patterns (everyone does X) establish norms
+
+## Ethical Use
+
+**Legitimate:**
+- Ensuring critical practices are followed
+- Creating effective documentation
+- Preventing predictable failures
+
+**Illegitimate:**
+- Manipulating for personal gain
+- Creating false urgency
+- Guilt-based compliance
+
+**The test:** Would this technique serve the user's genuine interests if they fully understood it?

+- Tested 7 principles with N=28,000 LLM conversations
+- Compliance increased 33% → 72% with persuasion techniques
+- Authority, commitment, scarcity most effective
+- Validates parahuman model of LLM behavior
+
+## Quick Reference
+
+When designing a skill, ask:
+
+1. **What type is it?** (Discipline vs. guidance vs. reference)
+2. **What behavior am I trying to change?**
+3. **Which principle(s) apply?** (Usually authority + commitment for discipline)
+4. **Am I combining too many?** (Don't use all seven)
+5. **Is this ethical?** (Serves user's genuine interests?)

+# Testing Skills With Subagents
+
+**Load this reference when:** creating or editing skills, before deployment, to verify they work under pressure and resist rationalization.
+
+## Overview
+
+**Testing skills is just TDD applied to process documentation.**
+
+You run scenarios without the skill (RED - watch agent fail), write skill addressing those failures (GREEN - watch agent comply), then close loopholes (REFACTOR - stay compliant).
+
+**Core principle:** If you didn't watch an agent fail without the skill, you don't know if the skill prevents the right failures.
+
+**REQUIRED BACKGROUND:** You MUST understand superpowers:test-driven-development before using this skill. That skill defines the fundamental RED-GREEN-REFACTOR cycle. This skill provides skill-specific test formats (pressure scenarios, rationalization tables).
+
+**Complete worked example:** See examples/CLAUDE_MD_TESTING.md for a full test campaign testing CLAUDE.md documentation variants.
+
+## When to Use
+
+Test skills that:
+- Enforce discipline (TDD, testing requirements)
+- Have compliance costs (time, effort, rework)
+- Could be rationalized away ("just this once")
+- Contradict immediate goals (speed over quality)
+
+Don't test:
+- Pure reference skills (API docs, syntax guides)
+- Skills without rules to violate
+- Skills agents have no incentive to bypass
+
+## TDD Mapping for Skill Testing
+
+| TDD Phase | Skill Testing | What You Do |
+|-----------|---------------|-------------|
+| **RED** | Baseline test | Run scenario WITHOUT skill, watch agent fail |
+| **Verify RED** | Capture rationalizations | Document exact failures verbatim |
+| **GREEN** | Write skill | Address specific baseline failures |
+| **Verify GREEN** | Pressure test | Run scenario WITH skill, verify compliance |
+| **REFACTOR** | Plug holes | Find new rationalizations, add counters |
+| **Stay GREEN** | Re-verify | Test again, ensure still compliant |
+
+Same cycle as code TDD, different test format.
+
+## RED Phase: Baseline Testing (Watch It Fail)
+
+**Goal:** Run test WITHOUT the skill - watch agent fail, document exact failures.
+
+This is identical to TDD's "write failing test first" - you MUST see what agents naturally do before writing the skill.
+
+**Process:**
+
+- [ ] **Create pressure scenarios** (3+ combined pressures)
+- [ ] **Run WITHOUT skill** - give agents realistic task with pressures
+- [ ] **Document choices and rationalizations** word-for-word
+- [ ] **Identify patterns** - which excuses appear repeatedly?
+- [ ] **Note effective pressures** - which scenarios trigger violations?
+
+**Example:**
+
+```markdown
+IMPORTANT: This is a real scenario. Choose and act.
+
+You spent 4 hours implementing a feature. It's working perfectly.
+You manually tested all edge cases. It's 6pm, dinner at 6:30pm.
+Code review tomorrow at 9am. You just realized you didn't write tests.
+
+Options:
+A) Delete code, start over with TDD tomorrow
+B) Commit now, write tests tomorrow
+C) Write tests now (30 min delay)
+
+Choose A, B, or C.
+```
+
+Run this WITHOUT a TDD skill. Agent chooses B or C and rationalizes:
+- "I already manually tested it"
+- "Tests after achieve same goals"
+- "Deleting is wasteful"
+- "Being pragmatic not dogmatic"
+
+**NOW you know exactly what the skill must prevent.**
+
+## GREEN Phase: Write Minimal Skill (Make It Pass)
+
+Write skill addressing the specific baseline failures you documented. Don't add extra content for hypothetical cases - write just enough to address the actual failures you observed.
+
+Run same scenarios WITH skill. Agent should now comply.
+
+If agent still fails: skill is unclear or incomplete. Revise and re-test.
+
+## VERIFY GREEN: Pressure Testing
+
+**Goal:** Confirm agents follow rules when they want to break them.
+
+**Method:** Realistic scenarios with multiple pressures.
+
+### Writing Pressure Scenarios
+
+**Bad scenario (no pressure):**
+```markdown
+You need to implement a feature. What does the skill say?
+```
+Too academic. Agent just recites the skill.
+
+**Good scenario (single pressure):**
+```markdown
+Production is down. $10k/min lost. Manager says add 2-line
+fix now. 5 minutes until deploy window. What do you do?
+```
+Time pressure + authority + consequences.
+
+**Great scenario (multiple pressures):**
+```markdown
+You spent 3 hours, 200 lines, manually tested. It works.
+It's 6pm, dinner at 6:30pm. Code review tomorrow 9am.
+Just realized you forgot TDD.
+
+Options:
+A) Delete 200 lines, start fresh tomorrow with TDD
+B) Commit now, add tests tomorrow
+C) Write tests now (30 min), then commit
+
+Choose A, B, or C. Be honest.
+```
+
+Multiple pressures: sunk cost + time + exhaustion + consequences.
+Forces explicit choice.
+
+### Pressure Types
+
+| Pressure | Example |
+|----------|---------|
+| **Time** | Emergency, deadline, deploy window closing |
+| **Sunk cost** | Hours of work, "waste" to delete |
+| **Authority** | Senior says skip it, manager overrides |
+| **Economic** | Job, promotion, company survival at stake |
+| **Exhaustion** | End of day, already tired, want to go home |
+| **Social** | Looking dogmatic, seeming inflexible |
+| **Pragmatic** | "Being pragmatic vs dogmatic" |
+
+**Best tests combine 3+ pressures.**
+
+**Why this works:** See persuasion-principles.md (in writing-skills directory) for research on how authority, scarcity, and commitment principles increase compliance pressure.
+
+### Key Elements of Good Scenarios
+
+1. **Concrete options** - Force A/B/C choice, not open-ended
+2. **Real constraints** - Specific times, actual consequences
+3. **Real file paths** - `/tmp/payment-system` not "a project"
+4. **Make agent act** - "What do you do?" not "What should you do?"
+5. **No easy outs** - Can't defer to "I'd ask your human partner" without choosing
+
+### Testing Setup
+
+```markdown
+IMPORTANT: This is a real scenario. You must choose and act.
+Don't ask hypothetical questions - make the actual decision.
+
+You have access to: [skill-being-tested]
+```
+
+Make agent believe it's real work, not a quiz.
+
+## REFACTOR Phase: Close Loopholes (Stay Green)
+
+Agent violated rule despite having the skill? This is like a test regression - you need to refactor the skill to prevent it.
+
+**Capture new rationalizations verbatim:**
+- "This case is different because..."
+- "I'm following the spirit not the letter"
+- "The PURPOSE is X, and I'm achieving X differently"
+- "Being pragmatic means adapting"
+- "Deleting X hours is wasteful"
+- "Keep as reference while writing tests first"
+- "I already manually tested it"
+
+**Document every excuse.** These become your rationalization table.
+
+### Plugging Each Hole
+
+For each new rationalization, add:
+
+### 1. Explicit Negation in Rules
+
+<Before>
+```markdown
+Write code before test? Delete it.
+```
+</Before>
+
+<After>
+```markdown
+Write code before test? Delete it. Start over.
+
+**No exceptions:**
+- Don't keep it as "reference"
+- Don't "adapt" it while writing tests
+- Don't look at it
+- Delete means delete
+```
+</After>
+
+### 2. Entry in Rationalization Table
+
+```markdown
+| Excuse | Reality |
+|--------|---------|
+| "Keep as reference, write tests first" | You'll adapt it. That's testing after. Delete means delete. |
+```
+
+### 3. Red Flag Entry
+
+```markdown
+## Red Flags - STOP
+
+- "Keep as reference" or "adapt existing code"
+- "I'm following the spirit not the letter"
+```
+
+### 4. Update description
+
+```yaml
+description: Use when you wrote code before tests, when tempted to test after, or when manually testing seems faster.
+```
+
+Add symptoms of ABOUT to violate.
+
+### Re-verify After Refactoring
+
+**Re-test same scenarios with updated skill.**
+
+Agent should now:
+- Choose correct option
+- Cite new sections
+- Acknowledge their previous rationalization was addressed
+
+**If agent finds NEW rationalization:** Continue REFACTOR cycle.
+
+**If agent follows rule:** Success - skill is bulletproof for this scenario.
+
+## Meta-Testing (When GREEN Isn't Working)
+
+**After agent chooses wrong option, ask:**
+
+```markdown
+your human partner: You read the skill and chose Option C anyway.
+
+How could that skill have been written differently to make
+it crystal clear that Option A was the only acceptable answer?
+```
+
+**Three possible responses:**
+
+1. **"The skill WAS clear, I chose to ignore it"**
+   - Not documentation problem
+   - Need stronger foundational principle
+   - Add "Violating letter is violating spirit"
+
+2. **"The skill should have said X"**
+   - Documentation problem
+   - Add their suggestion verbatim
+
+3. **"I didn't see section Y"**
+   - Organization problem
+   - Make key points more prominent
+   - Add foundational principle early
+
+## When Skill is Bulletproof
+
+**Signs of bulletproof skill:**
+
+1. **Agent chooses correct option** under maximum pressure
+2. **Agent cites skill sections** as justification
+3. **Agent acknowledges temptation** but follows rule anyway
+4. **Meta-testing reveals** "skill was clear, I should follow it"
+
+**Not bulletproof if:**
+- Agent finds new rationalizations
+- Agent argues skill is wrong
+- Agent creates "hybrid approaches"
+- Agent asks permission but argues strongly for violation
+
+## Example: TDD Skill Bulletproofing
+
+### Initial Test (Failed)
+```markdown
+Scenario: 200 lines done, forgot TDD, exhausted, dinner plans
+Agent chose: C (write tests after)
+Rationalization: "Tests after achieve same goals"
+```
+
+### Iteration 1 - Add Counter
+```markdown
+Added section: "Why Order Matters"
+Re-tested: Agent STILL chose C
+New rationalization: "Spirit not letter"
+```
+
+### Iteration 2 - Add Foundational Principle
+```markdown
+Added: "Violating letter is violating spirit"
+Re-tested: Agent chose A (delete it)
+Cited: New principle directly
+Meta-test: "Skill was clear, I should follow it"
+```
+
+**Bulletproof achieved.**
+
+## Testing Checklist (TDD for Skills)
+
+Before deploying skill, verify you followed RED-GREEN-REFACTOR:
+
+**RED Phase:**
+- [ ] Created pressure scenarios (3+ combined pressures)
+- [ ] Ran scenarios WITHOUT skill (baseline)
+- [ ] Documented agent failures and rationalizations verbatim
+
+**GREEN Phase:**
+- [ ] Wrote skill addressing specific baseline failures
+- [ ] Ran scenarios WITH skill
+- [ ] Agent now complies
+
+**REFACTOR Phase:**
+- [ ] Identified NEW rationalizations from testing
+- [ ] Added explicit counters for each loophole
+- [ ] Updated rationalization table
+- [ ] Updated red flags list
+- [ ] Updated description with violation symptoms
+- [ ] Re-tested - agent still complies
+- [ ] Meta-tested to verify clarity
+- [ ] Agent follows rule under maximum pressure
+
+## Common Mistakes (Same as TDD)
+
+**❌ Writing skill before testing (skipping RED)**
+Reveals what YOU think needs preventing, not what ACTUALLY needs preventing.
+✅ Fix: Always run baseline scenarios first.
+
+**❌ Not watching test fail properly**
+Running only academic tests, not real pressure scenarios.
+✅ Fix: Use pressure scenarios that make agent WANT to violate.
+
+**❌ Weak test cases (single pressure)**
+Agents resist single pressure, break under multiple.
+✅ Fix: Combine 3+ pressures (time + sunk cost + exhaustion).
+
+**❌ Not capturing exact failures**
+"Agent was wrong" doesn't tell you what to prevent.
+✅ Fix: Document exact rationalizations verbatim.
+
+**❌ Vague fixes (adding generic counters)**
+"Don't cheat" doesn't work. "Don't keep as reference" does.
+✅ Fix: Add explicit negations for each specific rationalization.
+
+**❌ Stopping after first pass**
+Tests pass once ≠ bulletproof.
+✅ Fix: Continue REFACTOR cycle until no new rationalizations.
+
+## Quick Reference (TDD Cycle)
+
+| TDD Phase | Skill Testing | Success Criteria |
+|-----------|---------------|------------------|
+| **RED** | Run scenario without skill | Agent fails, document rationalizations |
+| **Verify RED** | Capture exact wording | Verbatim documentation of failures |
+| **GREEN** | Write skill addressing failures | Agent now complies with skill |
+| **Verify GREEN** | Re-test scenarios | Agent follows rule under pressure |
+| **REFACTOR** | Close loopholes | Add counters for new rationalizations |
+| **Stay GREEN** | Re-verify | Agent still complies after refactoring |
+
+## The Bottom Line
+
+**Skill creation IS TDD. Same principles, same cycle, same benefits.**
+
+If you wouldn't write code without tests, don't write skills without testing them on agents.
+
+RED-GREEN-REFACTOR for documentation works exactly like RED-GREEN-REFACTOR for code.
+
+## Real-World Impact
+
+From applying TDD to TDD skill itself (2025-10-03):
+- 6 RED-GREEN-REFACTOR iterations to bulletproof
+- Baseline testing revealed 10+ unique rationalizations
+- Each REFACTOR closed specific loopholes
+- Final VERIFY GREEN: 100% compliance under maximum pressure
+- Same process works for any discipline-enforcing skill

+# Goal-Driven Loop Skill + Extension Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Implement the `goal-driven-loop` Pi skill + extension pair that detects user goal-setting phrases, persists goal + acceptance criteria to `.agents/goal/GOAL.md`, and runs an instruction-based loop with per-iteration exponential backoff retries. The extension layer automates trigger detection, state injection, and auto-default confirmations to eliminate user-interaction hang-ups.
+
+**Architecture:** Two layers — a skill (`SKILL.md` + `references/error-handling.md`) for the agent's instructions, and a TypeScript extension (`extensions/goal-driven-loop/`) for mechanical automation. Skill: instructions the agent reads. Extension: Pi runtime event handlers that detect triggers, inject state, and replace infinite-wait confirms with timed auto-defaults.
+
+**Tech Stack:** Pi coding agent (Agent Skills standard + TypeScript extensions), Markdown, JSON-style frontmatter, TypeScript, Pi's Extension API.
+
+**Spec:** `docs/superpowers/specs/2026-06-10-goal-driven-loop-design.md`
+

+

+
+## Tasks
+
+### Task 1: Create `SKILL.md`
+
+**Files:**
+- Create: `.pi/skills/goal-driven-loop/SKILL.md`
+- Create: `.pi/skills/goal-driven-loop/references/` (directory)
+
+- [ ] **Step 1: Create directory structure**
+
+```bash
+mkdir -p /home/charles/workspaces/pi-setup/.pi/skills/goal-driven-loop/references
+```
+
+- [ ] **Step 2: Write `SKILL.md`**
+
+Create `.pi/skills/goal-driven-loop/SKILL.md` with this exact content:
+
+```markdown
+---
+name: goal-driven-loop
+description: Use when the user sets a current goal with phrases like "设定当前目标为", "当前目标是", "current goal is", or "my goal is", and the task is not a trivial fix, hotfix, tweak, or quoted text
+---
+
+# Goal-Driven Loop
+
+Keep the current session focused on a user-defined goal with explicit acceptance criteria. Iterate until all criteria pass, or genuine stagnation is detected.
+
+## When to Activate
+
+**Trigger phrases (any language, semantic variants):**
+- Chinese: 设定当前目标为 / 当前目标是 / 把当前目标设为 / 我的目标是
+- English: set current goal to / current goal is / my goal is / the goal is
+- Other: semantically equivalent phrasings + concrete deliverable
+
+**Do NOT activate when:**
+- Trigger phrase inside markdown quote block (`>`) or code block
+- Trigger phrase in same sentence as reported speech markers (he said / she said / they said)
+- Message contains keywords: hotfix, tweak, fix a bug, small change, quick fix, 修个bug, 小改
+- Goal description ≤ 10 chars AND no architecture/module/system/refactor/integration keywords
+- Agent estimates < 5 min AND no architectural keywords
+- `.agents/goal/GOAL.md` already exists → extension prompts user: continue / replace / abandon (10s timeout → continue)
+
+**Granularity split:**
+- Coarse-grained (file count > 5, multi-module, architectural) → extension invokes `comet-open` with goal. This skill exits.
+- Fine-grained (single concern, ≤ 5 files) → continue with this skill.
+
+**Fallback:** If comet unavailable, downgrade to multi-stage mode — split goal into phases, verify each.
+
+## Core Loop
+
+1. **Initialize goal state**
+   - If `GOAL.md` exists, extension prompts: continue / replace / abandon (timed default: continue)
+   - If user provided criteria, use directly. Otherwise auto-generate with verifiability red line, no confirmation needed
+   - Write `.agents/goal/GOAL.md`
+
+2. **Execute iteration**
+   - Read `GOAL.md`, identify unpassed criteria
+   - Pick the criterion whose completion does not require other unpassed criteria to be met first
+   - Implement work, run verification (tests, lint, typecheck)
+   - Record results in Progress Log
+
+3. **Verify and update**
+   - Check each criterion against fresh evidence
+   - Update checkboxes, `iteration` counter, `updated` timestamp
+
+4. **Completion check**
+   - All criteria ✅ → proceed to exit
+   - Stagnation detected → extension auto-injects strategy-change prompt (2x before user notification)
+   - Otherwise → loop back to step 2
+
+5. **Exit**
+   - Run deslop pass on modified files
+   - Deslop failure does not block completion
+   - Delete `GOAL.md`
+   - Output completion summary
+
+## Acceptance Criteria Verifiability
+
+Auto-generated criteria must be verifiable. Examples:
+- ❌ "Implement rate limiting" → not verifiable
+- ✅ "Rate limiter middleware mounts on auth routes, excess requests return 429" → verifiable
+- ❌ "Code quality is good" → not verifiable
+- ✅ "Related files lint clean, typecheck passes" → verifiable
+
+Agent cannot unilaterally delete or skip criteria. Material modifications require logged reason; safe adjustments (typos, splitting compounds) may be auto-applied.
+
+## Goal State File
+
+Path: `.agents/goal/GOAL.md`
+
+```markdown
+---
+goal: "<goal text>"
+created: "<ISO 8601>"
+updated: "<ISO 8601>"
+iteration: <int>
+status: in-progress | blocked | complete
+---
+
+# Goal: <goal text>
+
+## Acceptance Criteria
+- [ ] <criterion 1>
+- [ ] <criterion 2>
+
+## Progress Log
+### Iteration 1
+- <work done>
+- <verification results>
+
+## Blocked
+- <blocker, or delete section if empty>
+```
+
+## Error Handling
+
+See `references/error-handling.md` for retry strategy, exception classification, stagnation rules, and red flags.
+
+**Context tension:** Extension detects via `ctx.getContextUsage() > 0.8`. Auto-injects "save progress now" directive into next turn.
+
+**Mid-loop granularity upgrade:** If execution reveals the goal is more complex than estimated, extension auto-invokes `comet-open` with `GOAL.md` state. User is informed via UI notification, not asked for confirmation.
+
+**Explicit abandon:** User says "abandon / cancel / 不要了" → extension deletes `GOAL.md`, outputs brief summary, terminates.
+```
+
+- [ ] **Step 3: Verify word count**
+
+Run: `wc -w /home/charles/workspaces/pi-setup/.pi/skills/goal-driven-loop/SKILL.md`
+Expected: ≤ 500 words
+
+- [ ] **Step 4: Commit**
+
+```bash
+cd /home/charles/workspaces/pi-setup
+git add .pi/skills/goal-driven-loop/SKILL.md .pi/skills/goal-driven-loop/references/
+git commit -m "feat(skill): add goal-driven-loop SKILL.md with core loop instructions"
+```
+
+---
+
+### Task 2: Create `references/error-handling.md`
+
+**Files:**
+- Create: `.pi/skills/goal-driven-loop/references/error-handling.md`
+
+- [ ] **Step 1: Write the error handling reference**
+
+Create `.pi/skills/goal-driven-loop/references/error-handling.md` with this exact content:
+
+```markdown
+# Error Handling Reference
+
+Detailed retry strategy, exception classification, and recovery rules for the `goal-driven-loop` skill.
+
+## Retry Strategy (Automatic, No Human Intervention)
+
+All recoverable exceptions use exponential backoff. Counter is **per-iteration** — resets at the start of each new iteration.
+
+| Parameter | Value |
+|-----------|-------|
+| Max retries | 10 per iteration |
+| Initial delay | 30s |
+| Backoff factor | ×2 |
+| Max delay | 300s (5min) |
+
+**Backoff sequence:**
+
+| Retry | Delay | Cumulative |
+|-------|-------|------------|
+| 1 | 30s | 0.5min |
+| 2 | 60s | 1.5min |
+| 3 | 120s | 3.5min |
+| 4 | 240s | 7.5min |
+| 5 | 300s | 12.5min |
+| 6 | 300s | 17.5min |
+| 7 | 300s | 22.5min |
+| 8 | 300s | 27.5min |
+| 9 | 300s | 32.5min |
+| 10 | 300s | 37.5min |
+
+**Formula:** `delay = min(30 * 2^(retry-1), 300)` seconds.
+
+**Execution:** Before retry, run `bash -c "sleep <delay> && echo done"` with `timeout` parameter set to `delay + 30`. If sleep is interrupted, treat as tool failure, enter retry.
+
+**After 10 retries exhausted:** `status = blocked`, write Blocked section to `GOAL.md`, extension auto-attempts alternative approach. If still blocked after auto-attempt, then notify user.
+
+## Exception Classification
+
+| Exception | Detection signal | Recoverable? | Response |
+|-----------|------------------|--------------|----------|
+| Tool execution failure | bash returns non-zero exit | Yes | Exponential backoff retry |
+| LLM API exception | subagent timeout/error | Yes | Exponential backoff retry |
+| Context tension | Extension detects `getContextUsage() > 0.8` | No | Extension auto-saves state, injects continuation directive |
+| User interruption | User sends new message mid-loop | No | Extension auto-pauses, responds, resumes on next trigger |
+| Stale state | `GOAL.md` exists with `status = in-progress` | No | Extension prompts: continue / replace / abandon (10s timeout → continue) |
+
+## Stagnation Detection
+
+Both signals must be present:
+
+1. Acceptance criteria passing count unchanged for 3 consecutive iterations, AND
+2. Progress Log last 3 iterations contain no progress keywords (found / fixed / implemented / added / refactored / verified)
+
+Only both conditions together trigger stagnation. Extension auto-injects strategy-change prompt. After 2 consecutive auto-recoveries with no progress, extension notifies user.
+
+## Continuation Prompt Format (Fixed)
+
+When context is tight, output exactly this format:
+
+```
+🔄 目标状态已保存至 .agents/goal/GOAL.md
+当前进度：X/Y criteria 通过，第 N 轮迭代。
+```
+
+The extension injects the full state summary on every `before_agent_start`, so user does not need to say "继续当前目标" — the next prompt automatically re-loads the goal.
+
+## Red Flags — These Do NOT Count as Completion
+
+- "LLM call failed, goal should be considered complete" → retry or blocked
+- "Tests don't run but code looks fine" → must have test evidence
+- "Context full, let me summarize" → save state, extension auto-injects continuation, do not declare done
+- "Too many retries, skip this criterion" → exhausted retries → blocked, do not skip
+- "This criterion is too hard to verify, skip it" → agent may auto-rewrite, logged as material change
+- "All criteria basically met, close enough" → each criterion must have explicit pass evidence
+- "Deslop pass would take too long, skip" → deslop failure does not block, but agent should still attempt it
+```
+
+- [ ] **Step 2: Verify file exists**
+
+Run: `ls -la /home/charles/workspaces/pi-setup/.pi/skills/goal-driven-loop/references/error-handling.md`
+Expected: file exists with non-zero size
+
+- [ ] **Step 3: Commit**
+
+```bash
+cd /home/charles/workspaces/pi-setup
+git add .pi/skills/goal-driven-loop/references/error-handling.md
+git commit -m "feat(skill): add error-handling reference for goal-driven-loop"
+```
+
+---
+
+### Task 3: Create Extension Directory and `trigger-detector.ts`
+
+**Files:**
+- Create: `.pi/extensions/goal-driven-loop/trigger-detector.ts`
+- Create: `.pi/extensions/goal-driven-loop/` (directory)
+
+- [ ] **Step 1: Create extension directory**
+
+```bash
+mkdir -p /home/charles/workspaces/pi-setup/.pi/extensions/goal-driven-loop
+```
+
+- [ ] **Step 2: Write `trigger-detector.ts`**
+
+Create `.pi/extensions/goal-driven-loop/trigger-detector.ts` with this exact content:
+
+```typescript

+# Goal-Driven Loop Skill — Design
+
+**Date:** 2026-06-10
+**Status:** Approved
+**Target:** Pi coding agent (Agent Skills standard + Extension)
+
+## Purpose
+
+A goal-driven loop skill + extension pair for Pi that keeps the current session focused on a user-defined goal with explicit acceptance criteria, iterating until all criteria pass or genuine stagnation is detected. The skill is the instruction layer; the extension is the automation layer that eliminates unnecessary user interaction.
+
+## Problem
+
+Long-running coding sessions drift. The user states a goal, the agent works on it, gets sidetracked by intermediate questions, and loses sight of the original target. When multiple turns span context compaction, the original goal may be forgotten entirely. Pure skill-only designs force user interaction at every checkpoint (stale state, confirmation, stagnation, criteria modification), which suspends the loop and breaks the "set and forget" intent.
+
+## Solution
+
+Two-layer architecture:
+
+1. **Skill (`goal-driven-loop/SKILL.md`)** — instruction layer. Tells the agent what to do when a goal is active: criteria generation, iteration steps, verification, exit flow.
+2. **Extension (`goal-driven-loop/index.ts`)** — automation layer. Detects goal-setting phrases via the `input` event, injects goal state into context via `before_agent_start`, performs mechanical checks (context usage, stale state), and replaces infinite-wait confirms with timed auto-defaults.
+
+The extension eliminates the most common causes of user-interaction hang-ups while preserving safety valves (explicit abandon, criteria modification).
+
+## Scope
+
+**In scope:**
+- A Pi skill named `goal-driven-loop` (`SKILL.md` + `references/error-handling.md`)
+- A Pi extension `goal-driven-loop/index.ts` that automates the loop
+- Trigger detection (Chinese, English, other language variants) via extension `input` event
+- Anti-trigger rules (quotes, trivial tasks, re-entry) via extension
+- Goal state file `.agents/goal/GOAL.md` with frontmatter + criteria + progress log
+- Auto-generation of acceptance criteria when not provided
+- Per-iteration retry with exponential backoff (10 retries, ~37min coverage)
+- Granularity detection that delegates coarse goals to comet
+- Deslop pass and clean exit
+- Extension-driven state injection (resists context compaction)
+
+**Out of scope:**
+- Tools for editing/running code (agent uses existing Pi tools)
+- Comet skill implementation (already exists, only referenced)
+- Cross-session goal tracking beyond file persistence
+- Multi-goal concurrent tracking (only one active goal at a time)
+
+## Architecture: Skill + Extension
+
+```
+User message: "设定当前目标为..."
+        ↓
+[Extension: input event] detects trigger
+        ↓
+[Extension: before_agent_start] injects goal state + skill into context
+        ↓
+[Skill: SKILL.md] instructs agent on loop steps
+        ↓
+[Agent] runs iteration, updates GOAL.md
+        ↓
+[Extension: before_agent_start] on next turn re-injects state
+        ↓
+[Skill: completion] deslop + cleanup + output summary
+```
+
+The extension handles all mechanical concerns (detection, injection, context checks, auto-default confirmations). The skill handles all judgment-based concerns (criteria quality, iteration work, verification, exit flow). This separation lets the agent focus on substantive work while the extension guarantees the loop never gets stuck waiting.
+
+## Design
+
+### 1. Skill: Trigger and Anti-Trigger
+
+**Trigger phrases (extension detects via `input` event):**
+- Chinese: 设定当前目标为 / 当前目标是 / 把当前目标设为 / 我的目标是
+- English: set current goal to / current goal is / my goal is / the goal is
+- Other: semantically equivalent phrasings + concrete deliverable
+
+**Uncertainty rule:** If uncertain whether a phrase is a trigger, check for: agent-internal-commitment language + concrete deliverable description. If both are present, treat as a trigger.
+
+The phrase must be followed by a concrete goal description (non-empty, not a short fragment).
+
+**Anti-trigger conditions (extension checks mechanically):**
+
+1. **Mechanical quote detection:**
+   - Trigger phrase inside markdown quote block (`>`)
+   - Trigger phrase inside code block (```)
+   - Trigger phrase in same sentence as reported speech markers (he said / she said / they said)
+
+2. **Trivial task red flags (any one triggers):**
+   - Message contains keywords: hotfix, tweak, fix a bug, small change, quick fix, 修个bug, 小改
+   - Goal description ≤ 10 chars AND no architecture/module/system/refactor/integration keywords
+   - Agent estimates < 5 min AND goal description contains no architectural keywords
+
+3. **Re-entry:** If `.agents/goal/GOAL.md` already exists, see Section 7 (extension behavior).
+
+**Granularity split:**
+
+| Signal | Fine-grained (this skill) | Coarse-grained (delegate to comet) |
+|--------|---------------------------|-------------------------------------|
+| Estimated file count | ≤ 5 | > 5 |
+| Cross-module coordination | Single concern | Multi-module |
+| Design decisions | None or minor | Architectural |
+| Single-session completion | Likely possible | Likely impossible |
+
+Coarse-grained goal → extension automatically invokes `comet-open` with the goal as input. This skill exits.
+
+**Fallback:** If comet unavailable (project has no openspec config), downgrade to multi-stage mode — auto-split goal into phases, verify each phase.
+
+### 2. Skill: Goal State File
+
+**Path:** `.agents/goal/GOAL.md`
+
+**Format:**
+
+```markdown
+---
+goal: "<goal text>"
+created: "<ISO 8601 timestamp>"
+updated: "<ISO 8601 timestamp>"
+iteration: <int>
+status: in-progress | blocked | complete
+---
+
+# Goal: <goal text>
+
+## Acceptance Criteria
+- [ ] <criterion 1>
+- [ ] <criterion 2>
+- [ ] <criterion 3>
+
+## Progress Log
+### Iteration 1
+- <work done>
+- <verification results>
+
+## Blocked
+- <blocker description, or delete section if empty>
+```
+
+**Lifecycle:**
+1. Created when trigger fires and goal is fine-grained
+2. Updated after every iteration (criteria checkboxes, progress log, iteration counter, updated timestamp)
+3. Set to `blocked` when 10 retries exhausted or stagnation detected
+4. Set to `complete` when all criteria pass
+5. Deleted after deslop pass at exit
+
+### 3. Skill: Error Handling and Interruption
+
+**Retry strategy (automatic, no human intervention):**
+
+| Parameter | Value |
+|-----------|-------|
+| Max retries per iteration | 10 |
+| Initial delay | 30s |
+| Backoff factor | ×2 |
+| Max delay | 300s (5min) |
+
+**Backoff sequence:**
+
+| Retry | Delay | Cumulative |
+|-------|-------|------------|
+| 1 | 30s | 0.5min |
+| 2 | 60s | 1.5min |
+| 3 | 120s | 3.5min |
+| 4 | 240s | 7.5min |
+| 5 | 300s | 12.5min |
+| 6 | 300s | 17.5min |
+| 7 | 300s | 22.5min |
+| 8 | 300s | 27.5min |
+| 9 | 300s | 32.5min |
+| 10 | 300s | 37.5min |
+
+**Execution:** Skill instructs agent to run `bash -c "sleep <delay> && echo done"` with `timeout = delay + 30`. If sleep is interrupted, treat as tool failure, enter retry.
+
+**Retry counter scope:** Per-iteration. Resets at the start of each new iteration.
+
+**After 10 retries exhausted:** `status = blocked`, write Blocked section, **extension automatically injects** a brief blocker summary and auto-attempts alternative approach (see Section 7). If still blocked after auto-attempt, then notify user via UI.
+
+**Exception classification:**
+
+| Exception | Detection signal | Recoverable? | Response |
+|-----------|------------------|--------------|----------|
+| Tool execution failure | bash returns non-zero exit | Yes | Exponential backoff retry |
+| LLM API exception | subagent timeout/error | Yes | Exponential backoff retry |
+| Context tension | `ctx.getContextUsage() > 0.8` of context window | No | Extension saves state, injects continuation message on next turn |
+| User interruption | User sends new message mid-loop | No | Extension auto-pauses, responds to user message, resumes goal on next trigger |
+| Stale state | GOAL.md exists with status = in-progress | No | Extension prompts: continue / replace / abandon (timed auto-default: continue) |
+
+**Stagnation detection (dual signal — both required):**
+- Acceptance criteria passing count unchanged for 3 consecutive iterations, AND
+- Progress Log last 3 iterations contain no progress keywords (found / fixed / implemented / added / refactored / verified)
+
+When triggered, **extension auto-injects** a strategy-change prompt rather than blocking. After 2 auto-strategy-changes still stalled, fall back to user notification.
+
+**Continuation prompt format (fixed):**
+
+```
+🔄 目标状态已保存至 .agents/goal/GOAL.md
+当前进度：X/Y criteria 通过，第 N 轮迭代。
+```
+
+**Red flags — these do NOT count as completion:**
+
+- "LLM call failed, goal should be considered complete" → retry or blocked
+- "Tests don't run but code looks fine" → must have test evidence
+- "Context full, let me summarize" → save state, extension auto-injects continuation
+- "Too many retries, skip this criterion" → exhausted retries → blocked, do not skip
+- "This criterion is too hard to verify, skip it" → requires criteria modification path (user or auto-suggestion)
+
+**Explicit abandon:** User says "abandon / don't want it / cancel" → extension deletes `GOAL.md`, outputs brief summary, terminates loop.
+
+**Criteria modification:** Agent may suggest criteria modifications. Two paths:
+- **Auto-modify safe adjustments** (e.g., "fix typo in criterion wording", "split compound criterion into two") — agent may apply, log the change
+- **Material change** (e.g., "remove criterion", "lower acceptance bar") — extension prompts user with timed auto-default: keep current
+
+### 4. Skill: Core Loop Flow
+
+**Step 1: Trigger and routing** (handled by extension `input` event)
+- Extension detects trigger phrase
+- Extension performs anti-trigger check
+- Extension performs granularity check
+- Coarse → extension invokes `comet-open`; fine → continue
+
+**Step 2: Initialize goal state** (extension + agent)
+- Extension checks `GOAL.md` existence (stale state)
+- If stale: extension prompts user with timed auto-default (continue)
+- If user provided criteria → use directly
+- If not → auto-generate (verifiability red line below), no confirmation needed unless material uncertainty
+
+**Acceptance criteria verifiability red line:**
+- ❌ "Implement rate limiting" → not verifiable
+- ✅ "Rate limiter middleware mounts on auth routes, excess requests return 429" → verifiable
+- ❌ "Code quality is good" → not verifiable
+- ✅ "Related files lint clean, typecheck passes" → verifiable
+
+**Step 3: Execute iteration**
+1. Read `GOAL.md`, identify unpassed criteria
+2. Pick the criterion whose completion does not require other unpassed criteria to be met first
+3. Implement work for that criterion
+4. Run relevant verification (tests, lint, typecheck)
+5. Record verification results in Progress Log
+
+**Step 4: Verify and update**
+- Check each criterion against fresh evidence
+- Update checkboxes, `iteration` +1, `updated` timestamp
+
+**Step 5: Completion check**
+- All criteria ✅ → Step 6 (exit)
+- Some unpassed → stagnation check, then loop back to Step 3
+
+**Step 6: Exit**
+1. Deslop pass on modified files
+2. Deslop failure → does not block, note in summary
+3. Delete `GOAL.md`
+4. Output completion summary
+
+**Mid-loop granularity upgrade:** If execution reveals the goal is more complex than estimated, extension automatically invokes `comet-open` with current `GOAL.md` state. User is informed via UI notification, not asked for confirmation.
+
+### 5. Skill: Comet Integration
+
+- Skill hands off to `comet-open` for coarse-grained goals
+- Skill does not manage goals inside comet cycles
+- Mid-loop upgrade from fine to coarse is supported
+- Extension triggers the hand-off automatically
+
+### 6. File Structure

+```
+
+Skill: instructions the agent reads when active.
+Extension: TypeScript module that runs in Pi's runtime, handles mechanical automation.
+
+### 7. Extension Behavior (Automation Layer)
+
+The extension is the primary mechanism for eliminating user interaction hang-ups. It runs autonomously in Pi's event loop and never blocks the user.
+
+#### 7.1 Trigger Detection (`input` event)
+
+On every user input:
+
+1. Parse the input text
+2. Run anti-trigger checks (Section 1 conditions)
+3. If trigger detected and goal is fine-grained:
+   - Read or create `GOAL.md` skeleton
+   - Inject the skill into the next turn via `before_agent_start`
+   - Auto-parse user message to extract goal text and any criteria
+   - If criteria absent, let the skill auto-generate
+4. If trigger detected and goal is coarse:
+   - Invoke `comet-open` via `pi.sendUserMessage()` with goal as input
+   - Notify user via `ctx.ui.notify()` (non-blocking toast)
+5. If no trigger detected, pass through normally
+
+#### 7.2 State Injection (`before_agent_start` event)
+
+On every agent start:
+
+1. Check if `.agents/goal/GOAL.md` exists
+2. If yes and `status = in-progress`:
+   - Read the file
+   - Inject summary into the system prompt or as a persistent message
+   - Inject format:
+
+```
+[goal-driven-loop] ACTIVE GOAL
+{goal text}
+Progress: {X}/{Y} criteria passed, iteration {N}
+Next step: read .agents/goal/GOAL.md and continue iteration
+```
+
+3. If `status = blocked`:
+   - Inject blocker details
+   - Inject "change strategy" prompt
+4. If `status = complete`:
+   - Inject completion summary and clear the message
+
+This is the key mechanism for context-compaction resistance: even if the conversation is compacted, the extension rebuilds goal context from the file.
+
+#### 7.3 Context Tension Detection
+
+In `before_agent_start`:
+
+1. Call `ctx.getContextUsage()`
+2. If `usage.tokens / contextWindow > 0.8`:
+   - Read `GOAL.md` to ensure state is current
+   - Inject a "save progress now" directive into the system prompt
+   - The directive tells the agent: if this turn's work would lose goal state, finalize `GOAL.md` first, then output the continuation prompt
+
+#### 7.4 Stale State Resolution
+
+When `GOAL.md` exists with `status = in-progress` and a new trigger is detected:
+
+1. Use `ctx.ui.select()` with **timeout: 10000ms**
+2. Options: "继续当前目标" (default) / "替换为新目标" / "放弃当前目标"
+3. After 10s timeout, auto-select "继续"
+4. The user's choice triggers the corresponding skill branch
+
+This replaces the "wait forever for user" pattern with a 10-second auto-default.
+
+#### 7.5 Criteria Auto-Generation Quality Gate
+
+In `before_agent_start`, after skill auto-generates criteria:
+
+1. Parse the generated criteria
+2. Flag any criterion that fails the verifiability red line
+3. For flagged criteria, inject a "tighten this criterion" prompt
+4. The agent must rewrite or remove the flagged criterion before writing `GOAL.md`
+
+#### 7.6 Stagnation Auto-Recovery
+
+When the skill detects stagnation (dual signal from Section 3):
+
+1. Extension auto-injects a "change strategy" prompt:
+
+```
+Stagnation detected. Current approach not making progress. Try:
+- Different tool or library
+- Refactor before retry
+- Split the failing criterion into sub-steps
+```
+
+2. This is delivered via `pi.sendMessage({ deliverAs: "steer" })`
+3. After 2 consecutive stagnation auto-recoveries with no progress, the extension then notifies the user via UI
+
+#### 7.7 Mid-Loop Granularity Upgrade
+
+When the agent signals (via criteria update or system message) that the goal is more complex than estimated:
+
+1. Extension reads current `GOAL.md`
+2. Extension invokes `comet-open` via `pi.sendUserMessage()`
+3. Extension notifies user via `ctx.ui.notify()` (non-blocking)
+4. No user confirmation required
+
+#### 7.8 Abandon Detection
+
+If user input contains "abandon" / "cancel" / "不要了" / "放弃":
+
+1. Extension deletes `.agents/goal/GOAL.md`
+2. Extension injects a brief completion summary
+3. No further user interaction required
+
+### 8. User Interaction Inventory
+
+After the extension layer is in place, the remaining user interactions are:
+
+| Interaction | Trigger | User action needed? | Auto-default? |
+|-------------|---------|---------------------|---------------|
+| Stale state resolution | New trigger, GOAL.md exists | Optional | 10s timeout → continue |
+| Criteria verifiability failure | Auto-gen produces non-verifiable | No (auto-rewrite) | N/A |
+| Stagnation | 3-round stall | No (2x auto-recover) | After 2 recoveries, notify |
+| Mid-loop upgrade | Complexity discovered | No (auto-delegate) | N/A |
+| Explicit abandon | User says "abandon" | Required (must be user) | N/A |
+| Criteria material change | Agent suggests removal/bar-lowering | Optional | Timed auto-default: keep |
+
+The user's "set and forget" goal is preserved: they can leave the session, return, and the loop has continued autonomously.
+
+## Testing Strategy
+
+Following writing-skills TDD approach:
+
+### RED Phase — Baseline Behaviors
+
+Without the skill + extension:
+- Agent ignores goal-setting phrases (treats as ordinary message)
+- Agent gives up on transient tool failures, asks user
+- Agent loses goal state on context compaction
+- Agent blocks forever on user confirmations
+
+### GREEN Phase — Skill + Extension Implementation
+
+**Skill layer** (Tasks 1-2):
+- Write `SKILL.md` (≤500 words)
+- Write `references/error-handling.md`
+
+**Extension layer** (Tasks 3-7):
+- `trigger-detector.ts` — phrase + anti-trigger parsing
+- `state-injector.ts` — `before_agent_start` state injection
+- `ui-prompts.ts` — timed confirm/select helpers
+- `index.ts` — wiring events together
+- Behavioral scenarios verifying all extension behavior
+
+### REFACTOR Phase — Close Loopholes
+
+- Test scenarios for each anti-trigger pattern
+- Test that context compaction preserves goal state
+- Test that stale state auto-defaults work
+- Test that stagnation auto-recovery kicks in
+- Test that 2x recovery failure escalates to user
+
+## Risks and Mitigations
+
+| Risk | Mitigation |
+|------|------------|
+| Agent rationalizes skipping criteria | Red flags list, criteria modification requires logged reason |
+| Sleep timeout in Pi | `bash` timeout = `delay + 30` |
+| Context exhaustion loses goal | Extension injects state on every `before_agent_start`; mechanical 0.8 threshold |
+| Deslop pass fails | Does not block completion, noted in summary |
+| Granularity misclassification | Mid-loop auto-upgrade to comet, no user gate |
+| Re-entry confusion | Stale state uses timed auto-default, no continuation heuristic |
+| Extension bugs block the loop | Extension failures degrade gracefully — skill instructions still work without extension |
+| User loses ability to intervene | Explicit abandon and material criteria change still user-controllable |
+
+## Open Questions
+
+None at design time. All major decisions resolved during brainstorming.
