WHY IT NEEDS A POLICY

Why ims_handoff_create needs a policy

The tool creates or stores handoff data (likely session transitions or context transfers) in the IMS backend, which is reversible via update/delete operations. This is a Write action rather than Read (no 'create' implies data generation) or Destructive (creation is not irreversible).

From the tool's definition Tool name 'ims_handoff_create' indicates creation of a handoff record or session state in the Integrated Memory System. The 'create' verb and context of IMS session management suggest writing data to persistent memory storage.
