WHAT IT DOES

What atualizar_codebase does on Maestro

AI agents use atualizar_codebase to create or update resources in Maestro — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Maestro environment.

WHY IT NEEDS A POLICY

Why atualizar_codebase needs a policy

The tool updates codebase information, which is a write operation. Marked as [Interno] (Internal), suggesting it modifies internal state or metadata about the codebase. The description is minimal, reducing confidence. Since it updates rather than deletes, Write is the appropriate category, though if it overwrites code files it could be more severe.

From the tool's definition 'Atualiza informações do codebase' — 'Atualiza' means 'Updates' in Portuguese, indicating a write/modification operation on the codebase information.
