Why delete_coupon is rated Critical

The rule that runs delete_coupon safely

delete_coupon 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 Ghl, apply this rule, and every delete_coupon call is checked against it from then on.
