The rule that runs outbox_clean safely

outbox_clean 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 Mcp Hands, apply this rule, and every outbox_clean call is checked against it from then on.
