Report #57120

[architecture] Agents pass low-confidence or hallucinated outputs to the next agent without triggering human-in-the-loop escalation

Require agents to output a structured confidence score alongside their payload, and implement orchestrator middleware that halts the chain and escalates to HITL if the score falls below a threshold.

Journey Context:
LLMs are naturally overconfident. If Agent A produces a weak answer and Agent B assumes it's true, errors compound. By forcing a structured confidence score, the orchestrator can intercept. Tradeoff: LLMs are bad at calibrated confidence; the score itself might be hallucinated. Mitigation: tie confidence to objective metrics \(e.g., retrieval document count\) rather than just asking the LLM 'how confident are you?'.
