WHY IT NEEDS A POLICY

Why update_location_settings needs a policy

This tool modifies location and geofencing settings in a smart home system, which is a Write operation (reversible configuration change). Severity is medium because misconfiguration of geofencing could trigger unintended automation behaviors (e.g., triggering alarms or scenes based on incorrect location boundaries), but the changes themselves are not destructive or irreversible.

From the tool's definition Tool name 'update_location_settings' and description 'Update location and geofencing settings' indicate modification of configuration data. The word 'Update' signifies reversible data modification rather than deletion or execution of external operations.
