Understand why this is happening\n2. Suggest a fix\n3. Explain how to prevent similar bugs`,\n\n  \"feature:\": (desc) => `I want to implement this feature: ${desc}\n\nPlease:\n1.

Impor limites rígidos antes de chamar `session.send()`.\n\n5. **Mantenha o processamento rápido** - Esse hook é executado em cada mensagem do usuário. Evite operações lentas.\n\n## Consulte também\n\n* [Usar ganchos](/pt/copilot/how-tos/copilot-sdk/hooks)\n* [Ganchos de ciclo de vida de sessão](/pt/copilot/how-tos/copilot-sdk/hooks/session-lifecycle)\n* [Gancho de uso de pré-ferramenta](/pt/copilot/how-tos/copilot-sdk/hooks/pre-tool-use)"}
