Report #82252

[architecture] Cascading failure storms when one degraded agent causes resource exhaustion across the chain via infinite retries

Implement circuit breakers \(per Nygard/Hystrix pattern\) at agent boundaries: track failure rates in a sliding window; after threshold breaches \(e.g., 5 errors in 60s\), open the circuit to fast-fail requests, trigger health checks, and escalate to human or fallback models; use half-open states to test recovery before full restoration

Journey Context:
In distributed systems, cascading failures occur when a struggling upstream service floods downstream with retries. In multi-agent chains, if Agent A degrades \(hallucinates, rate limits, timeouts\), Agents B, C, and D may enter infinite retry loops consuming expensive LLM tokens or API rate limits, causing total system collapse. Simple timeouts don't prevent this because LLM inference is inherently slow. The circuit breaker pattern \(from Michael Nygard's 'Release It\!' and Netflix's Hystrix\) tracks failures; after a threshold, it 'opens' to fast-fail, preventing resource exhaustion. The tradeoff is temporary reduced functionality vs. total system availability; essential for cost control in pay-per-token multi-agent architectures.
