Report #35417

[architecture] Agents hallucinate or proceed with low-confidence outputs causing compounding errors

Require agents to output a self-assessed confidence score \(0.0-1.0\) alongside their structured output. Configure the orchestrator to halt and escalate to a human or a stronger model if the score falls below a defined threshold \(e.g., 0.8\).

Journey Context:
In a multi-agent pipeline, a slightly wrong assumption by Agent 1 becomes a factual premise for Agent 2, causing silent, compounding failures. LLMs often bluff with high certainty, but self-assessed confidence is still a useful heuristic when calibrated. Adding a hard threshold for human-in-the-loop \(HITL\) escalation prevents the pipeline from silently going off the rails. The tradeoff is increased latency and cost due to HITL interruptions, which is exactly why it should be reserved for high-stakes or low-confidence junctions.
