Why atualizar_anexo needs a policy

This tool modifies metadata of an attachment reversibly—a classic Write operation. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or read-only retrieve data (Read). Severity is medium because unintended metadata changes could affect document organization or access control, but the impact is contained to a single attachment's metadata and reversible.

From the tool's definition Tool name 'atualizar_anexo' (update attachment) and description 'Atualiza os metadados de um anexo' (Updates the metadata of an attachment) indicate a modification operation on existing data.
