What delete_huly_permission does on Huly
AI agents call delete_huly_permission to permanently remove resources in Huly, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_huly_permission is rated Critical
This tool irreversibly deletes permission objects from the Huly system. While it includes safety measures (namespaced built-ins are protected, referenced permissions are refused), the core operation is permanent deletion which cannot be undone. The blast radius is high because deleting permissions could break access control and system functionality, though it appears scoped to custom permissions only.
From the tool's definition Tool description explicitly states 'Permanently delete a custom Huly Permission' and 'resolved by exact ID or exact label'. The word 'Permanently' and 'delete' combined indicate irreversible deletion of data.

delete_huly_permission is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Huly, apply this rule, and every delete_huly_permission call is checked against it from then on.
