What runbook steps resolve stuck, looping or duplicated agent execution runs?

The core initial step to resolve stuck, looping or duplicated agent execution runs on agent platforms is validating workflow state against durable execution records to confirm the root cause. For stuck runs, check for unhandled tool or model timeouts; for duplicated runs, review concurrency control configurations. It is critical to note that containment steps for duplicated runs do not prevent future instances without additional guardrails, as containment is not prevention.
