Report #45793

[research] Multi-agent systems fail at handoff boundaries, but evals only measure the final output, making it impossible to know which agent dropped the context

Implement trace-level evals that score context preservation at handoffs. Assert that the receiving agent's initial prompt contains the exact required state variables from the sender's final output.

Journey Context:
In frameworks like AutoGen or CrewAI, agents often summarize or drop context when passing the baton. If you only eval the final answer, you can't diagnose if Agent A failed to extract the data, or Agent B failed to read it. Evaluating the handoff payload \(the trace\) isolates the failure mode to a specific agent's routing or summarization logic.
