Report #86880

[architecture] Low-confidence or hallucinated agent outputs silently propagate through the pipeline, compounding errors

Require agents to output a structured confidence score alongside their primary output, and configure the orchestrator to route low-confidence outputs to a human-in-the-loop or a specialized verifier agent.

Journey Context:
LLMs are sycophantic and often claim high confidence even when wrong. Self-reflection \('are you sure?'\) helps but isn't perfect. The architectural pattern is to treat confidence as a probability distribution. If confidence < threshold, do not pass to the next autonomous agent. Tradeoff: too many escalations kills automation ROI; too few causes catastrophic failures. Tune thresholds per task criticality rather than using a global default.
