Report #27313
[architecture] Agents hallucinate high confidence on ambiguous tasks, preventing automatic escalation to humans
Implement a dual-verification confidence score: require the agent to output a self-assessed confidence score \(0.0-1.0\) AND compute an independent heuristic score \(e.g., embedding distance of output to input, or logprob variance\). Trigger human-in-the-loop if either falls below threshold.
Journey Context:
LLMs are notoriously bad at self-assessing confidence; they often output 0.9 even when wrong. Relying solely on the LLM's self-score is a common trap. By combining self-score with an independent metric \(like checking if the output schema is minimally filled, or semantic similarity to the prompt\), you get a more reliable trigger. The tradeoff is added latency and compute for the heuristic, but it prevents silent failures where an agent confidently proceeds down a hallucinated path.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
