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.

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 | $0.00115 | $0.01592 |
| Opus 5 | $0.00057 | $0.00796 |
| Sonnet 5 | $0.00023 | $0.00318 |
| Haiku 4.5 | $0.00012 | $0.00159 |
Grade A, and why
ler-um-contrato 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 9d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ler um contrato
Quando usar
- "extraia a {cláusula} deste contrato" (documento único).
- "quais são os termos de renovação automática em todos os contratos desta pasta" (em lote).
- "extraia o limite de responsabilidade e a linguagem de rescisão do contrato-mestre de serviços da {fornecedor}".
Conexões que eu preciso
Eu executo trabalho externo através do Composio. Antes desta habilidade rodar, eu verifico se as categorias abaixo estão conectadas. Faltando → eu nomeio a categoria, peço para você conectar na aba Integrações, e paro.
- Arquivos (Google Drive) - Obrigatório para execuções em lote e buscas por fornecedor específico. Eu vasculho pastas ou contratos nomeados aqui.
- Processamento de documentos (OCR ou extração de texto de PDF) - Obrigatório. Extrai o texto real de PDFs escaneados ou nativos para eu poder extrair as cláusulas ao pé da letra.
Se nenhum provedor de arquivos estiver conectado e você não tiver colado o contrato, eu paro e peço para você conectar o Google Drive ou colar o documento.
Informações que eu preciso
Eu leio o seu contexto operacional primeiro. Para cada campo obrigatório que estiver faltando, eu faço UMA pergunta em linguagem simples (melhor modalidade: app conectado > arquivo enviado > URL > colar) e espero.
- O contrato em si - Obrigatório. Por que eu preciso: não posso extrair do nada. Se estiver faltando, eu pergunto: "Envie o contrato ou me indique a pasta. PDF, Word ou um Google Doc, tudo funciona."
- Postura com fornecedores - Obrigatório. Por que eu preciso: define quais termos contam como alerta. Uma postura conservadora sinaliza mais agressivamente do que uma postura de risco rápido. Se estiver faltando, eu pergunto: "Como você lida com termos de fornecedores, conservador, equilibrado, ou avançar rápido?"
- Documento de contexto operacional - Obrigatório. Por que eu preciso: ancora os limites inegociáveis para eu sinalizar cláusulas que os violariam. Se estiver faltando, eu pergunto: "Quer que eu configure seu contexto operacional primeiro? Ajuda a identificar termos desfavoráveis com mais confiança."
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.
