Report #58838

[architecture] Cascading failures when a downstream agent enters a degraded state

Wrap every inter-agent call in a Circuit Breaker \(Hystrix pattern\): track error rates in a sliding window; after threshold \(e.g., 50% errors in 30s\), open the circuit and fast-fail to a fallback agent or cached response; half-open after cooldown to test recovery.

Journey Context:
Agents are unreliable \(hallucination, latency spikes\). Without isolation, one slow agent exhausts the thread pool of the caller, causing systemic collapse. Retries amplify the problem. Circuit breakers contain the blast radius by failing fast. Trade-off: you need sophisticated fallback logic \(graceful degradation\) and careful tuning of thresholds to avoid flapping.
