What cancel_print_service_order does on Kiln
AI agents call cancel_print_service_order to permanently remove resources in Kiln, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why cancel_print_service_order is rated Critical
Cancelling a print service order is irreversible: once cancelled, the order is terminated, any queued job is aborted, and the prior state cannot be restored. This maps to Destructive rather than Write because the action cannot be undone. Severity is high because misuse could abort in-progress print jobs, waste materials, and disrupt manufacturing workflows.
From the tool's definition 'Cancel a print service order' — cancellation of a service order is an irreversible action that terminates an active order and cannot be undone.
