Skill Stocktake

Audits all crucible skills for overlap, staleness, broken references, and quality.

Announce at start: "I'm using the stocktake skill to audit skill health."

When to Activate

• User invokes /stocktake or asks to audit skills
• Forge feed-forward nudges when results are 30+ days stale
• After adding, removing, or significantly modifying multiple skills

Modes

Mode	Trigger	Duration
Quick scan	results.json exists (default)	~5 min
Full stocktake	results.json absent, or /stocktake full	~20 min
Efficiency report	/stocktake efficiency	~5 min

Results cache: skills/stocktake/results.json

Quick Scan Flow

1. Read skills/stocktake/results.json
2. Identify skills that have changed since evaluated_at timestamp (compare file mtimes)
3. If no changes: report "No changes since last run." and stop
4. Re-evaluate only changed skills using the same evaluation criteria
5. Carry forward unchanged skills from previous results
6. Output only the diff
7. Save updated results to skills/stocktake/results.json

Phase 1 — Inventory

Enumerate all skill directories under skills/. For each:

• Read SKILL.md frontmatter (name, description, origin)
• Collect file mtime
• Note file count and total line count

Structural invariants (repo-level). Run the tracked invariant checker from the repo root and treat a non-zero exit as a stocktake failure to surface:

• python3 scripts/check_i2_marker.py — the I2 engine-dispatch marker allowlist: the set of files carrying a column-0 `dispatch: delve-engine` body line must equal exactly {delve, temper} (a stray third dispatcher or a missing one fails). Added #336.
• python3 scripts/check_qg_stagnation_minor.py — the Minor-aware stagnation judge contract: asserts quality-gate/stagnation-judge-prompt.md carries the Step-3 Mixed-branch Minor-accumulation rule + the Consecutive recurring-Minor rounds counter + the DR-Cause enum; that quality-gate/SKILL.md's Minor prose is reconciled (the bare "do not count toward stagnation" claim is gone; path-pinned, literal match); and that the convergence-log dr_cause value set (minor-accumulation | structural-saturation | consensus | null) is documented. Added #260.
• python3 scripts/check_crossref.py — the cross-reference invariant: every live crucible:<token> in a git-tracked *.md resolves to a real skills/<token>/ dir. Plugin-namespaced agent types (the crucible-* namespace, e.g. crucible-red-team) are resolved against agents/<token>.md (so a typo'd agent ref is still caught); documented template placeholders (skill-name/old-name/new-name) are blanket-exempt. docs/plans/, docs/prds/, and docs/handoffs/ are gitignored and thus naturally excluded since git ls-files lists tracked files only (so new files under those paths are not scanned); tracked surfaces — skills/**, top-level docs/*.md, docs/research/, etc. — ARE scanned. --selftest runs the resolution-logic regression cases. Added #365.
• python3 scripts/catalog.py check — the generated skill-catalog contract: asserts docs/skills.md's <!-- CATALOG:START/END --> rows are in bijection with skills/*/SKILL.md frontmatter names (no omission, no bogus entry, no naming mismatch), every on-disk skill is in CATEGORIES (and vice-versa, no dangling category), and every registered count token (README, workshop, plugin.json) equals the runtime skill count n. Added #364.
• python3 scripts/check_calibration_dispatch.py — the calibration-weighted-dispatch wiring invariant: asserts each of the 5 consumers (siege, quality-gate, inquisitor, delve, audit) carries the <!-- CANONICAL: shared/calibration-weighted-dispatch.md --> marker + its own advise <skill> invocation, and that none inlines the convention's prose body (the net-new no-copy assertion check_canonical_drift/check_crossref don't cover). --selftest runs the marker/invocation/no-copy logic cases. Added #372.
• python3 scripts/check_model_pins.py — the model-tier guardrail: no fable-family pin (fable/claude-fable-5, case-insensitive, across frontmatter model: + inline Task tool/Agent tool forms) on any <!-- MODEL-TIER: security-hard-out -->-marked file, AND every file in the security-surface set (skills/siege/**, skills/dependency-audit/**, agents/crucible-red-team.md, plus narrow offensive/CVE name-stems gated match-then-check-for-pin; audit/test-coverage/stocktake carved out) carries the marker (default-deny). Static tracked-*.md pins only — inherit/session-model roles and untracked consensus config are disclosed residuals (see skills/shared/model-tier-policy.md). --selftest runs the detection-logic cases. Added #392.

(Other tracked checkers under scripts/check_*.py may be run here too as they are brought into alignment.)

Phase 2 — Quality Evaluation

Dispatch an Opus Explore agent with all skill contents and the evaluation checklist.

Each skill is evaluated against:

• Content overlap with other skills checked
• Scope fit — name, trigger, and content aligned
• Actionability — concrete steps vs vague advice
• Cross-references — do crucible: links resolve to existing skills?
• Convention drift — does a skill that dispatches subagents carry the <!-- CANONICAL: shared/dispatch-convention.md --> / return-convention.md markers (vs. copying or omitting them)?
• Eval presence — does the skill have an evals/ directory, or is one warranted given its surface? (eval-before-publish; flag absence, don't auto-fail — evals are aspirational across the suite)

Each skill gets a verdict:

Verdict	Meaning
Keep	Useful and current
Improve	Worth keeping, specific improvements needed
Retire	Low quality, stale, or cost-asymmetric
Merge into [X]	Substantial overlap with another skill; name the merge target

Reason quality requirements — the reason field must be self-contained and decision-enabling:

• For Retire: state (1) what specific defect was found, (2) what covers the same need instead
• For Merge: name the target and describe what content to integrate
• For Improve: describe the specific change needed (what section, what action)
• For Keep: restate the core evidence for the verdict

Phase 3 — Summary Table

Skill	Verdict	Reason

Phase 4 — Consolidation

1. Retire / Merge: present detailed justification per skill before confirming with user
2. Improve: present specific improvement suggestions with rationale
3. Save results to skills/stocktake/results.json

Efficiency Report Flow

Triggered by /stocktake efficiency or by forge feed-forward when 10+ chronicle signals with efficiency data exist.

Step 1: Load Chronicle Data

1. Read ~/.claude/projects/<hash>/memory/chronicle/signals.jsonl
2. If the file is missing or empty: report "No efficiency data available. Run a pipeline with enriched manifest tracking to begin collecting data." and stop.
3. Filter to signals that have a metrics.efficiency sub-object.
4. If fewer than 3 signals have efficiency data: report available data with caveat: "Insufficient data for trend analysis. N signals available, 3+ recommended for meaningful comparison."
5. Report: "N of M total signals include efficiency data." (where M is total signals, N is signals with efficiency).

Step 2: Per-Skill Summary

Group filtered signals by skill. For each skill, compute:

• Runs: count of signals
• Avg Est. Tokens (in+out): average of (est_input_tokens + est_output_tokens) across runs
• Avg Duration: average duration_m
• Avg Dispatches: average total dispatches (sum of dispatches_by_tier values)
• Rework %: average rework_pct across runs. If rework_pct is missing (pre-rework-tracking signal), display "—"
• Trend: compare last 3 runs vs prior 3 runs — "improving" (fewer tokens), "stable" (within 10%), or "increasing" (more tokens). "insufficient data" if fewer than 4 runs.

If any skill has average rework >30%, append a note: "[skill]: rework >30% — consider reviewing dispatch templates or quality-gate prompts for this skill."

Output:

## Skill Efficiency Report
**Period:** <oldest signal date> to <newest signal date>
**Tracked runs:** N
**Disclaimer:** Estimates based on dispatch file sizes (chars/4). Actual token consumption may vary +/-30%.

### Per-Skill Summary
| Skill | Runs | Avg Est. Tokens (in+out) | Rework % | Avg Duration | Avg Dispatches | Trend |
|-------|------|--------------------------|----------|--------------|----------------|-------|

Step 3: Dispatch Breakdown

For each skill, compute dispatch tier distribution and categorize dispatches as review vs. implementation:

• Opus/Sonnet/Haiku %: from dispatches_by_tier averaged across runs
• Review %: dispatches with role containing "reviewer", "red-team", "quality-gate", "adversarial" as a percentage of total
• Impl %: remaining dispatches as a percentage of total

Note: Review vs. implementation breakdown requires reading manifest entries (role field). If manifests are not available (only chronicle signals), report "N/A" for these columns.

Output:

### Dispatch Breakdown
| Skill | Opus % | Sonnet % | Haiku % | Review % | Impl % |
|-------|--------|----------|---------|----------|--------|

Step 4: Structural Efficiency

For each skill, compute:

• Avg Input/Dispatch: average total_input_chars / total dispatches — measures context per subagent
• Context Distribution: qualitative assessment — "focused" (<5000 chars avg/dispatch), "moderate" (5000-15000), "heavy" (>15000)
• Quality Overhead %: review dispatches / total dispatches * 100 — what fraction of work is quality assurance (requires manifest data; "N/A" if unavailable)

Output:

### Structural Efficiency
| Skill | Avg Input/Dispatch | Context Distribution | Quality Overhead % |
|-------|--------------------|-----------------------|--------------------|

Step 5: Baseline Comparison (Structural)

For each skill with sufficient data (3+ runs):

• Avg Total Context: average (total_input_chars + total_output_chars) per run — total context the pipeline touched
• Avg Input/Dispatch: average total_input_chars / total dispatches per run — how much context each subagent receives on average
• Context Focus Ratio: avg input per dispatch / avg total context — lower values mean each subagent sees a smaller slice of the total, indicating effective context distribution
• Quality Investment: review dispatches / total dispatches — fraction of dispatches dedicated to quality assurance (requires manifest data; "N/A" if only chronicle signals available)

Output:

### Baseline Comparison (Structural)
| Skill | Avg Total Context | Avg Input/Dispatch | Context Focus Ratio | Quality Investment |
|-------|-------------------|--------------------|---------------------|--------------------|

**Interpretation:** Context focus ratio measures how much of the total pipeline context each
subagent receives. Lower values mean more focused dispatches. Quality investment shows the
fraction of dispatches dedicated to review, red-team, and quality gates. These are structural
comparisons, not cost savings claims — they measure how the skill distributes work, not what
a monolithic alternative would cost.

Step 6: Cache Results

Save efficiency report data to skills/stocktake/results.json under a new efficiency key (separate from the skill verdict cache):

{
  "efficiency": {
    "computed_at": "2026-04-07T10:00:00Z",
    "signals_with_efficiency": 15,
    "total_signals": 42,
    "per_skill": {
      "build": { "runs": 8, "avg_est_tokens": 52600, "avg_duration_m": 45, "trend": "stable" },
      "debugging": { "runs": 5, "avg_est_tokens": 25000, "avg_duration_m": 22, "trend": "improving" }
    }
  }
}

Results File Schema

skills/stocktake/results.json:

{
  "evaluated_at": "2026-03-07T10:00:00Z",
  "mode": "full",
  "skills": {
    "skill-name": {
      "path": "skills/skill-name/SKILL.md",
      "verdict": "Keep",
      "reason": "Concrete, actionable, unique value for X workflow",
      "mtime": "2026-01-15T08:30:00Z"
    }
  }
}

Safety

• Never auto-deletes or auto-modifies skills
• Always presents findings and waits for explicit user confirmation
• Archive/delete operations always require user approval

Integration

• crucible:forge — Feed-forward checks stocktake results timestamp; nudges when 30+ days stale
• Evaluation is blind: same checklist applies regardless of skill origin

Red Flags

• Deleting or modifying skills without user confirmation
• Treating the checklist as a numeric score rather than holistic judgment
• Writing vague verdicts ("unchanged", "overlaps") instead of decision-enabling reasons
