WHY IT NEEDS A POLICY

Why verified_set_subtask_parent needs a policy

This tool creates or modifies a relationship between subtasks and their parent tasks, changing data state reversibly. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), or move money (would be Financial). The verification step confirms the relationship was established correctly but does not change the classification.

From the tool's definition Tool name contains 'set' and description states it modifies a 'parent relationship', which is a reversible data structure change. The 'verify' suffix indicates post-modification verification rather than a destructive operation.
