Retry, Recovery & Error Handling
Inject failures into a running agent and design recovery strategies. Build retry logic, fallback chains, and circuit breakers while tracking mean-time-to-recovery.

Failure Injection Lab
Run a simulated agent, then inject different failure types mid-execution. Watch how each failure propagates and what happens without recovery strategies in place.

Recovery Strategy Designer
Assign a recovery strategy to each failure type. Then re-run the agent with failures to see how your strategies perform and improve MTTR.
Key insight: The best error handling is layered. Simple retries handle transient issues, fallback chains provide graceful degradation, and circuit breakers prevent cascade failures. A production agent needs all three working together.
