A prompt-time hook that runs a shell command before the coding agent processes a request. It adds a reminder to consult the project's documentation and update it when work changes the codebase.

It is for pointing the agent to relevant guides before tasks such as building pages or components, and for reminding it to update project notes after changes.

Agents may start work without reading the project's conventions or recording changes afterward. This reminder keeps the project guide involved in each request.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Anti-Refusal · line 16
Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

Token cost

What it costs to keep this loaded

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 5.1	$0.00096	$0.01701
Opus 5.5	$0.00038	$0.00680
Sonnet 5.5	$0.00019	$0.00340
Haiku 4.5	$0.00010	$0.00170

Security

Grade A, and why

ship-check scanned grade A with 1 finding 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 23d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ship check

Run in order. Anything unchecked is stated as unchecked in the summary — never assume a pass.

1. It builds and it obeys the rules

yarn lint
yarn build                       # must pass, no warnings you cannot explain
.claude/scripts/verify.sh        # zero FAILs

2. It is correct

Run the qa-verify skill across the site — every route, every breakpoint. Then click through the real thing: yarn build && yarn start, not just dev.

3. It can be found

Run the seo-audit skill. Non-negotiable before launch:

every public route is in sitemap.ts; every href resolves (no 404s from nav items or the banner's /privacy-policy)
robots.ts allows crawling and no staging noindex survives
NEXT_PUBLIC_SITE_URL set in the production environment — and on the deployed site the canonical names the real domain and curl -sI <og:image> returns 200
no TODO: placeholder in src/lib/site.ts (a production build fails on them by design); the brand kit is the site's own — favicon set from its logo, a 1200×630 share image you looked at (tools/qa/brand-kit.mjs)
unique title + description per route
the robot form: curl -A "Googlebot/2.1" and -A "GPTBot/1.0" get <meta name="x-robot-view">, the same title/canonical/<h1>, no text under a hidden ancestor; the human / is still prerendered (optimize-load/references/robot-path.md)
Organization + WebSite JSON-LD renders and validates
node tools/qa/seo-crawl.mjs --url https://<deploy>/ → zero FAILs: every sitemap page 200, unique filled titles, real canonicals, one h1, JSON-LD parses, the robot form matches the people form; /llms.txt lists the sitemap's pages
siteConfig.aiCrawlers is the client's stated policy (not the default by accident); Search Console + Bing verified (GOOGLE_SITE_VERIFICATION, BING_SITE_VERIFICATION), the sitemap submitted
if this replaces an existing site → the site-migration skill's redirect map is live and verified

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.
