Report #75444

[architecture] Agent propagates hallucinated or low-confidence output down the chain because it lacks a mechanism to express uncertainty

Require the agent to return a structured \`confidence\_score\` \(0.0-1.0\) alongside its primary payload. Set an escalation threshold in the orchestrator; if below threshold, route to a human-in-the-loop or a specialized verification agent.

Journey Context:
LLMs are sycophantic and overconfident. If you just ask 'are you sure?', they say yes. By forcing a numerical score in a structured output, you create a machine-readable metric the orchestrator can act on programmatically. Tradeoff: LLMs are bad at calibrated probabilistic scores; the score is often a proxy for 'how standard is this request' rather than true accuracy. Still, it's highly effective for catching out-of-distribution queries.
