Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00041 | $0.00909 |
| Opus 5 | $0.00020 | $0.00454 |
| Sonnet 5 | $0.00008 | $0.00182 |
| Haiku 4.5 | $0.00004 | $0.00091 |
Grade A, and why
stocktake-skills scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Stocktake Skills
HARD GATE — HARD GATE — Skill inventory must be current. Missing HARD GATEs, stale descriptions, or broken verify commands are defects, not cosmetic. Fix them in
evolve-skill.
Audit SKILL.md catalog for drift, stale triggers, missing HARD GATEs, and INDEX mismatches.
Modes
| Mode | Scope |
|---|---|
| Quick Scan | Skills changed since last tag or in current diff |
| Full | All skills per SKILL-INDEX.md + catalog audit |
| --verify | Run bash scripts/run-skill-verify.sh and append health results to the stocktake report |
Process
- Catalog validator (code-enforced) — run
bash scripts/validate-skill-catalog.sh. Any FAIL is a critical finding before manual review. Add--archiveto list zero-usage skills frommetrics.skill_timingsfor auto-archiving candidates (move tospecs/epics/archive/or delete after user confirms). 0b. Agentic STE audit (e79s04) — runbash scripts/validate-agentic-ste.sh --audit skills/. Flag hedge words and sentences over 20 words per AGENTIC-STE.md. Record WARN lines in the stocktake report as STE debt — do NOT rewrite the full catalog in one pass. Route critical repeat offenders toevolve-skill. - Run
bash scripts/audit-catalog.shto verify pi/skills ↔ source SKILL.md sync. Mismatch is a critical finding. - Run mode; for each skill check: exists, verb-noun, <300 lines total, HARD GATE present, INDEX row matches.
- Write
specs/STOCKTAKE-<date>.mdwith findings table (skill, issue, severity). - Effectiveness report (--full mode only): Read
specs/state.yamlmetrics.skill_timingsand report:- Top 5 most-used skills (by calls, total_seconds)
- Skills with zero calls (potential dead weight)
- Skills with high average time (candidates for
evolve-skill)
- Critical findings →
plan-workstory; cosmetic →evolve-skillcandidate. - --verify mode: Run
bash scripts/run-skill-verify.shand append a## Verify Healthsection to the stocktake report:"N/68 PASS, M FAIL, K SKIP". FAIL skills are critical findings and go straight toplan-work.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

stocktake-skills is a cursor rule published in the GitHub repository danielvm-git/bigpowers (163 stars, last pushed 2d ago), licensed MIT. It adds 41 tokens to every session and 909 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
