WHY IT NEEDS A POLICY

Why drive_batch_update_permissions needs a policy

Permission updates modify file access control settings reversibly—they can be changed back by reapplying different permissions. This is a Write operation, not Destructive (no deletion) or Execute (no code execution). Severity is high because an agent misusing this could grant unauthorized access to sensitive files across multiple documents, compromising confidentiality and compliance.

From the tool's definition Tool description explicitly states 'Update permissions for multiple files at once'. The verb 'Update' and scope 'multiple files' indicate modification of access control metadata.
