Delete a Primary IP (unassigns from server if assigned; server must be off)
AI agents call delete_primary_ip to permanently remove resources in Hcloud — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a Primary IP address resource from the Hetzner Cloud infrastructure. While the description notes the server must be off, the deletion itself cannot be undone and represents irreversible data loss.
From the tool's definition Tool name is 'delete_primary_ip' and description states 'Delete a Primary IP'. The verb 'delete' combined with the irreversible removal of a network resource indicates a destructive operation.

Yes. Add a rate_limit block to the delete_primary_ip rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
