Report #79758

[architecture] Cascading failures when low-confidence agent outputs propagate through chains

Implement confidence thresholds \(0.0-1.0\) with circuit breaker logic: if confidence < threshold, halt chain and escalate to human or fallback agent; open the circuit after N consecutive validation failures

Journey Context:
LLM-based agents hallucinate; passing uncertain outputs downstream compounds errors. Simple thresholding isn't enough because temporary degradation shouldn't permanently break the chain. The circuit breaker pattern \(from microservices\) fits here: after N consecutive low-confidence responses, 'open' the circuit and stop trying for a cooldown period. Tradeoff: adds latency for confidence calculation \(may require secondary LLM call for calibration\). Common mistake: using the same threshold for all agent types; retrieval agents need different thresholds than generation agents.
