WHY IT NEEDS A POLICY

Why create_fulfillment needs a policy

This tool creates fulfillment records and modifies order state by marking items as shipped. While this is a significant business operation (misuse could cause customer confusion or false shipment claims), it is reversible—fulfillments can be cancelled or corrected. It falls under Write (creates or modifies data reversibly) rather than Destructive.

From the tool's definition Tool description states it 'marks items as shipped' and 'optionally adds tracking info.' These are create/modify operations on fulfillment records (reversible state changes), not irreversible deletions.
