Report #22299

[frontier] Cascading failures when LLM hallucinations or tool errors propagate through agent chains

Implement circuit breakers that trip when error rate > threshold or latency > p99, returning degraded responses rather than cascading

Journey Context:
Without circuit breakers, a single failing tool or hallucinating LLM can cause an infinite loop or exponential retry storm in multi-agent systems. By adapting the SRE pattern of circuit breakers \(from Release It\! and Google SRE books\), agents monitor their own health metrics. When hallucination detection \(via consistency checks\) or tool failure rates exceed thresholds, the breaker opens, forcing the agent to return a safe fallback or escalate to human review. This prevents 'crazy agent' scenarios where agents loop indefinitely.
