[research] Agent handoffs lose critical context or hallucinate state when transferring tasks to sub-agents

Implement trace-level evals specifically on the handoff boundary. Assert that the receiving agent's initial context contains all required entities from the sender's final output, using exact match or embedding similarity, before executing the sub-agent.

Journey Context:
It is common to evaluate the final output of a multi-agent system, treating the internal handoffs as a black box. When a multi-agent system fails, the root cause is often a degraded or hallucinated summary passed during the handoff. By evaluating the handoff payload itself \(the message passed from Agent A to Agent B\), you isolate context-drift from tool-execution failures.
