WHY IT NEEDS A POLICY

Why update_user_password needs a policy

This tool modifies user account data (password) reversibly through a standard update operation. While password changes are sensitive and could impact account security if misused by an agent (e.g., locking out the legitimate user), the operation itself is a Write action that changes data rather than Destructive (irreversible deletion) or Execute (arbitrary code/command).

From the tool's definition Tool name 'update_user_password' and description 'Update the current user's password using a Mealie-native payload' indicate modification of user account credentials.
