Report #76906

[architecture] Cascading hallucinations from low-confidence agent outputs passed as facts

Require agents to emit a structured confidence score \(or explicit uncertainty tokens\) and route outputs below a threshold to a verification agent or human-in-the-loop, rather than the next worker agent.

Journey Context:
Agents often hallucinate with high linguistic confidence, and downstream agents assume upstream outputs are factual, compounding errors. Simply prompting 'be confident' fails. By forcing the agent to output a numerical confidence score in a separate schema field, and defining a threshold \(e.g., <0.8\) that triggers an escrow/escalation path, you break the error cascade. The tradeoff is increased latency and potential human bottlenecks, but it prevents catastrophic autonomous actions based on weak signals.
