AI agents call ebay_bulk_cancel_packages to permanently remove resources in Ebay — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Canceling packages is an irreversible action that destroys fulfillment records and potentially voids customer orders. While the impact is scoped to logistics data rather than permanent deletion of inventory, the inability to undo the cancellation and the business consequence (unfulfilled commitments) places this in Destructive rather than Write. The bulk nature amplifies risk.
From the tool's definition 'Cancel multiple packages in one request' - this operation terminates shipments/orders which cannot be reversed and results in loss of fulfillment state and customer commitments.
