WHY IT NEEDS A POLICY

Why gdrive_auth_complete needs a policy

This tool writes sensitive authentication credentials (refresh_token) to a configuration file (.env), which is a reversible but security-critical modification. It does not delete data (not Destructive), does not execute arbitrary code (not Execute), and does not move money (not Financial). The Write category applies because it creates/modifies configuration state.

From the tool's definition Tool exchanges authorization code for refresh_token and persists it to .env file ('Lưu refresh_token vào .env'). This modifies configuration files and stores sensitive credentials.
