Report #68877

[architecture] Agents proceed with low-confidence outputs causing compounding errors down the chain

Require agents to output a discrete confidence score alongside their structured output, and implement an orchestrator routing rule: if confidence is below threshold, route to a human-in-the-loop queue or a specialized verifier agent.

Journey Context:
LLMs are naturally overconfident; asking for probability yields garbage. However, asking for a categorical confidence based on specific criteria \(e.g., 'Did I find the exact API endpoint?'\) allows the orchestrator to gate execution. The tradeoff is added latency for the confidence evaluation and potential HITL bottlenecks, but this prevents catastrophic autonomous failures in high-stakes pipelines.
