WHAT IT DOES

WHY IT NEEDS A POLICY

Why set_user_password needs a policy

This tool modifies user account state (password) but the change is reversible—another password can be set later. It is not a destructive deletion. However, it carries high severity because unauthorized password changes could lock legitimate users out of their accounts or enable account takeover, especially on an autonomous infrastructure platform serving paid coding agents.

From the tool's definition Tool name 'set_user_password' and description 'Change, reset, or set a user' indicate modification of user account credentials.
