WHY IT NEEDS A POLICY

Why configure_safe_mode needs a policy

This tool creates or modifies configuration state reversibly. It does not read data (Read), execute arbitrary operations (Execute), delete data (Destructive), or move money (Financial). The severity is low because misconfiguration of a safety setting has minimal direct impact; worst case, it changes the user's operational mode.

From the tool's definition The tool name includes 'configure' and the description states it 'Configure[s] safe mode for destructive operations' — it modifies a configuration setting rather than performing a destructive action itself.
