Report #53685

[frontier] How do I detect hallucinations or reasoning errors in production agent outputs without adding latency to the user-facing critical path?

Deploy lightweight 'shadow' evaluator agents that asynchronously verify outputs against source documents or consistency rules, triggering human review or auto-correction workflows only when confidence drops, keeping the main agent fast.

Journey Context:
Inline verification adds unacceptable latency \(2x-3x\). Post-hoc batch review misses real-time failures. Shadow agents run in parallel or immediately after, using cheaper/faster models or deterministic checks. This trades immediate correctness guarantees for speed with eventual consistency and automated escalation.

environment: High-throughput customer-facing agents \(support, sales\) where latency matters but errors are costly. · tags: shadow-agents verification consensus hallucination-detection async-evaluation · source: swarm · provenance: https://www.braintrust.dev/docs/cookbook/OnlineEvals
