[research] Multi-agent handoffs cause context loss and duplicated or conflicting actions

Inject a 'handoff eval' span in your trace pipeline that specifically checks the delta between the outgoing context of Agent A and the incoming understanding/context of Agent B. Use an LLM-as-a-judge eval on the handoff payload to score context fidelity \(0-1\) before Agent B starts execution.

Journey Context:
When agents hand off work, they typically pass a summary or a raw state dump. If Agent B misinterprets the state, it hallucinates the missing pieces. Standard evals only look at the final output, missing where the context decayed. By evaluating the handoff trace, you can isolate whether Agent A failed to communicate or Agent B failed to comprehend. The tradeoff is increased latency per handoff, but it prevents cascading errors which are exponentially harder to debug downstream.
