Report #61201

[architecture] Agents hallucinate or fail silently, passing bad data down the chain without flagging uncertainty

Require agents to output a self-assessed confidence score \(0.0-1.0\) alongside their primary payload, and implement a routing gate that escalates to a human or fallback agent if the score is below a threshold.

Journey Context:
LLMs are eager to please and will make up answers. In a single agent, this is bad; in a chain, it compounds. By forcing a confidence score into the schema, you create an actionable metric. If score < 0.8, halt the chain. Tradeoff: LLMs are notoriously bad at calibrated confidence \(they are overconfident\). To mitigate this, ask for a chain-of-thought justification for the score before the score itself, which improves calibration.
