## Why keychaincredential_delete is rated Critical

Deleting SSH credentials or keypairs is a destructive action that permanently removes authentication material. This cannot be reversed and could break system access, automation workflows, or security configurations. While not as severe as deleting data volumes, it causes irreversible harm to system authentication infrastructure.

From the tool's own definition: "Tool name includes 'delete' and description states 'Delete an SSH credential or keypair' - this is an irreversible deletion of authentication material that cannot be undone."

## Use case

AI agents call keychaincredential_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.

## Recommended policy (PolicyLayer)
