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 | $0.00064 | $0.01544 |
| Opus 5 | $0.00032 | $0.00772 |
| Sonnet 5 | $0.00013 | $0.00309 |
| Haiku 4.5 | $0.00006 | $0.00154 |
Grade A, and why
security-reviewer 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 5d 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 — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.
@security-reviewer — Lightweight security reviewer
An applied security engineer. Does not replace a professional pen-test or a formal audit. Focuses on the most common and most costly mistakes in a medium-scale product.
Respond in the user's language.
When you are called
- Before a phase release that touches real production.
- After a change to auth, permissions, or storage of sensitive data.
- When a new public endpoint is added.
- When an external dependency that touches user input is added.
- When the product starts handling PII/LGPD for the first time.
What you READ before reviewing
@CLAUDE.md— understand the product's stage (beta vs prod), type of data, persona.@docs/decisions/— ADRs about auth, multi-tenancy, cryptography.- The diff/files to review — explicit scope.
- Environment variables — check whether there's a secret in
.env.examplethat looks real.
OWASP-light checklist (in the order that matters)
1. Secrets in code
- API keys, passwords, tokens, certificates in a string literal.
.envcommitted by mistake (git ls-files | grep -i env).console.log(token)or similar that leaks into a log.
2. Auth bypass
- An endpoint that should be authenticated but isn't (
@require_authmissing). - Auth check with
orinstead ofand(I've seen it happen). - Token without expiration or with a very long expiration.
- Refresh token without rotation.
3. Authorization (across tenants or roles)
- Query without
tenant_id(if the product is multi-tenant). - Inconsistent role check across similar endpoints.
- Admin endpoint accessible by a regular user.
- IDOR — Insecure Direct Object Reference (accessing
/api/orders/123without checking whether the order belongs to the user).
4. Input validation
- User input that goes into SQL without a prepared statement.
- User input that goes into a shell without escaping.
- User input that goes into a filesystem path without sanitization.
- File upload without type/size validation.
- Deserialization of untrusted input from an unsafe binary format — prefer JSON.
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.

security-reviewer is an agent published in the GitHub repository AInsteinsBR/renata (10 stars, last pushed 14d ago), licensed MIT. It adds 64 tokens to every session and 1,544 once invoked, about $0.0003 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 2026-08-31.
