WHAT IT DOES

What generate_print_certificate does on Kiln

AI agents use generate_print_certificate to create or update resources in Kiln — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kiln environment.

WHY IT NEEDS A POLICY

Why generate_print_certificate needs a policy

Generating certificates creates new data that could be stored or transmitted, making this a Write operation. Severity is medium because misuse could create fraudulent certificates (e.g., falsifying print job records or device credentials), but the blast radius is limited compared to financial or destructive operations.

From the tool's definition Tool name 'generate_print_certificate' suggests creation of a document or credential. The empty description prevents direct confirmation, but the verb 'generate' implies producing new data.
