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 5.1 | $0.00040 | $0.02431 |
| Opus 5 | $0.00020 | $0.01215 |
| Sonnet 5 | $0.00008 | $0.00486 |
| Haiku 4.5 | $0.00004 | $0.00243 |
Grade A, and why
review-security 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 11d 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.
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.
How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Review security
Run a security-focused review: HTTP security headers, CSP, bot protection (when implemented), CORS/CSRF, input validation, secret management, dependency vulnerabilities, and error information leakage. Your reply must be a plan of suggested changes: concise, actionable, and structured-not only prose.
Invocation
Text after the slash command is additional scope/focus - narrow the review accordingly. If none given, use the default scope described below.
Best practices alignment
- Headers - CSP with nonces or strict-dynamic where needed; X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy; HSTS in production where applicable (often platform +
hono/secure-headerson API). - Input validation - All external input (API bodies, query params, path params) validated with Zod schemas from
@repo/dtos-commonand@hono/zod-validatorwhere applicable; use.strict()on schemas when appropriate; reject unknown keys; sanitize for context (HTML, URL, etc.) where output. - Secrets - Never in repo or client bundle; only in
.dev.varsor wrangler env; no logging or error messages that include secrets. - Bot protection - Turnstile (or equivalent) on sensitive endpoints when implemented; token verified server-side before any processing; no bypass for "trusted" clients without verification.
- CORS and CSRF - CORS allowlist (no wildcard in production); preflight handled; state-changing
/api/*requests protected (e.g.hono/csrfwith same-site / origin rules per AGENTS.md patterns). - Errors and logging - No stack traces or internal paths in client-facing responses; safe logging (no sensitive data); consistent Hono error handling (
HTTPException,onError).
Align with root AGENTS.md and apps/worker-api/AGENTS.md for env and validation patterns.
Legal-sector delta: this skill covers the generic surface (headers, CSP, CORS/CSRF, validation,
dependency audit). The client-privilege rules - identifiers in logs, traces, cache keys and error
bodies; matter/tenancy isolation; retention on durable writes; document text treated as untrusted
input; third-party disclosure - live once in the privileged-legal-data
skill, with the always-loaded prohibitions in guardrails.md.
Apply both; do not restate that checklist here.
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.

review-security is a skill published in the GitHub repository louisbrulenaudet/monorepo-template (19 stars, last pushed 10d ago), licensed Apache-2.0. It adds 40 tokens to every session and 2,431 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
