WHAT IT DOES

What certificate_delete does on Truenas

AI agents call certificate_delete to permanently remove resources in Truenas, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why certificate_delete is rated Critical

The tool permanently deletes a certificate by ID, which is an irreversible action. Certificates are critical infrastructure components for TLS/SSL operations, authentication, and system security. Deleting a certificate cannot be undone and will cause immediate service disruption for any services relying on that certificate.

certificate_delete Hidden

certificate_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
