Report #76625

[architecture] Agents proceed with low-confidence or hallucinated outputs in critical chains, causing compounding errors instead of halting

Require agents to output a structured confidence score \(0.0-1.0\) alongside their primary payload. Define explicit threshold triggers in the orchestrator: if confidence is below threshold, route to a human-in-the-loop queue or a specialized verification agent.

Journey Context:
LLMs are inherently sycophantic and will confidently output wrong answers. Relying on implicit confidence is impossible. Explicit scoring forces the model to evaluate its own certainty. Tradeoff: LLMs are notoriously bad at calibration; the score might be artificially high. However, combining this with output length or entropy checks provides a workable heuristic for when to interrupt the chain.
