Report #95144

[architecture] Agents silently propagate hallucinations or low-confidence outputs to downstream agents

Require agents to output a structured confidence score \(0.0-1.0\) alongside their primary payload, and configure the orchestrator to route scores below a threshold to a fallback agent or human-in-the-loop.

Journey Context:
Agents often bluff. If Agent A isn't sure, it still generates a plausible answer that Agent B treats as fact. Asking 'are you sure?' doesn't work reliably. By forcing a structured confidence field, the orchestrator can deterministically check the threshold. The tradeoff is that LLM confidence scores are often poorly calibrated \(overconfident\), so the threshold must be tuned empirically, and combining it with external verification yields better results than confidence alone.
