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 | $0.00047 | $0.00384 |
| Opus 5.5 | $0.00019 | $0.00154 |
| Sonnet 5.5 | $0.00009 | $0.00077 |
| Haiku 4.5 | $0.00005 | $0.00038 |
Grade A, and why
ag-referencia-seguranca-rules 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 1mo 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
Seguranca — Regras Inegociaveis
Banco de Dados
- RLS (Row Level Security) ativo em TODAS as tabelas, sem excecao
- Audit trail obrigatorio: tabela
audit_logscom JSONB (quem, o que, quando, onde, resultado) - Migrations sequenciais — nunca pular numeracao
- Indices desde o inicio (nao como afterthought)
Dados
- NUNCA logar: password, token, secret, apiKey, creditCard, PII
- LGPD: Base legal para cada tratamento, direito ao esquecimento, minimizacao de dados
- Mascaramento automatico de PII em contexto de IA
Niveis de Permissao (quando aplicavel)
| Nivel | Acesso |
|---|---|
| superadmin | Acesso total, gerencia usuarios |
| core_team | Projetos internos |
| external_agent | Projetos atribuidos |
| client | Somente leitura |
Checklist de Seguranca para Novas Features
- RLS policies definidas para todas as tabelas novas?
- Audit log implementado para operacoes sensiveis?
- PII mascarado em logs e contexto de IA?
- Base legal LGPD documentada para tratamento de dados?
- Secrets em env vars (nunca hardcoded)?
- Input validation com Zod em todos os endpoints?

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.

ag-referencia-seguranca-rules is a skill published in the GitHub repository andregusman-raiz/a-gusman-claude (18 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 384 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
