Report #56869

[architecture] Agent hallucinates instead of escalating uncertain multi-step reasoning

Require agents to output a structured confidence score alongside their answer, and configure the orchestrator to trigger a human-in-the-loop checkpoint if the score falls below a defined threshold.

Journey Context:
LLMs are overconfident. In a multi-agent setup, an overconfident hallucination cascades, poisoning the context for all downstream agents. Asking the LLM to self-score is imperfect but acts as a necessary circuit breaker. The tradeoff: LLMs are bad at absolute calibration, so thresholds must be tuned empirically per task. Alternatives like consistency sampling are too slow for real-time chains.
