RECOMMENDED RULE

The rule that runs plan_batch_change safely

plan_batch_change Allowed

plan_batch_change is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Trace, apply this rule, and every plan_batch_change call is checked against it from then on.
