Report #45197
[architecture] Error propagation through agent chains without quality gating
Implement a confidence-based circuit breaker: extract token-level log probabilities or use a verifier model to generate confidence scores \(0.0-1.0\). If <0.7, trip the circuit and escalate to human; if 0.7-0.9, retry with temperature=0 and top\_p=0.1; if >0.9, proceed. Maintain a half-open state for recovery testing.
Journey Context:
Binary pass/fail validation is too coarse for stochastic LLM outputs. Simple thresholding ignores calibration—an uncalibrated model may always output 0.99 confidence. The circuit breaker pattern \(from distributed systems\) prevents cascade failures: when one agent's output quality degrades \(detected via dropping confidence\), the system halts rather than contaminating downstream agents. The tradeoff is increased latency from verifier models, but this is necessary for high-stakes agent chains.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
