Report #56373

[architecture] Agents confidently propagate hallucinations or low-certainty outputs to downstream agents without triggering human review

Implement explicit confidence scoring via structured output and define an escalation threshold that routes to a human-in-the-loop \(HITL\) checkpoint instead of the next agent.

Journey Context:
LLMs are sycophantic and overconfident. If Agent A is unsure but outputs a definitive answer, Agent B will just assume it's true. Asking the LLM to self-score \(while imperfect\) combined with deterministic checks \(e.g., 'did the tool return an empty result?'\) creates a composite confidence score. If the score is below the threshold, halt the agent chain and push to a human queue. Tradeoff: LLM self-scoring is noisy and often requires calibration; too low a threshold swamps humans, too high lets errors through.
