Report #85079

[architecture] Single agent failure causes infinite retry loops or resource exhaustion across the chain

Implement circuit breakers that halt requests to a failing agent after 5 consecutive errors or 30s latency threshold, returning fallback values or halting the workflow and alerting operators.

Journey Context:
Without circuit breakers, one degraded agent \(e.g., slow LLM or failing tool\) creates backpressure that timeouts don't solve—retries hammer the failing service and cascade to dependent agents. Circuit breakers isolate faults and preserve system stability. Tradeoff: requires distributed state storage \(Redis/memory\) and careful threshold tuning to avoid flapping. Alternatives like exponential backoff alone don't prevent thundering herds during mass failures.
