Report #39539

[architecture] Low-confidence agent outputs silently propagate downstream, compounding hallucinations into irreversible system states

Require agents to output a structured confidence score alongside their primary payload. Configure the orchestrator to route scores below a threshold to a human-in-the-loop queue or a specialized verifier agent, rather than the next execution agent.

Journey Context:
Agents are inherently sycophantic and will guess rather than admit ignorance. Passing a guessed answer to the next agent treats it as ground truth. By forcing a confidence score as a separate schema field, the orchestrator can objectively evaluate routing. The tradeoff is latency: HITL queues add massive delay, so thresholds must be tuned per use case \(strict for financial/medical, loose for summarization\).
