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 | $0.00157 | $0.00157 |
| Opus 5 | $0.00078 | $0.00078 |
| Sonnet 5 | $0.00031 | $0.00031 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
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 2d 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.
What it actually says
Segurança
- Nenhum segredo, token ou chave de API hardcoded ou versionado; use env/secrets.
- Dados sensíveis em armazenamento seguro (Keychain/Keystore), nunca em texto puro.
- Toda comunicação por HTTPS; sem endpoints inseguros.
- Valide e sanitize toda entrada externa (usuário, resposta de API, deep link).
- Não registre (log) dados sensíveis ou pessoais.
- Dependências sem vulnerabilidades conhecidas e mantidas atualizadas.
- Sessão/token com expiração e renovação seguras; limpe credenciais no logout.
- Builds de produção ofuscados/minificados; ferramentas de debug desabilitadas em release.
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 is a cursor rule published in the GitHub repository cmaranho/rn-agent-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 157 tokens to every session, about $0.0008 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.
