Report #78343

[architecture] Unverified low-confidence agent outputs propagate down the chain, compounding errors

Require agents to output a structured confidence score or explicit 'unknown' state alongside their primary output. Configure the orchestrator to trigger a human-in-the-loop \(HITL\) checkpoint if the score is below a threshold or if the agent lacks tool access to verify.

Journey Context:
LLMs are sycophantic and prone to confident hallucinations. If an agent is asked a question it cannot answer, it will guess, and passing a guess to the next agent compounds the error. By forcing a confidence score as a schema contract, you make uncertainty machine-readable. The tradeoff is that LLMs are bad at self-assessing confidence; therefore, confidence should often be derived heuristically \(e.g., did the retrieval tool return empty?\) rather than relying solely on the LLM's self-reported score.
