Report #2472

[research] Multi-agent handoffs cause context loss or bloat, leading to downstream agent failures

Implement trace-level evals that inspect the exact payload passed between agents. Assert that the payload contains necessary context IDs and excludes irrelevant history, scoring the handoff payload against a schema or rubric, not just the final task outcome.

Journey Context:
When Agent A hands off to Agent B, it typically passes a summarized or full history. If A summarizes poorly, B lacks context; if A passes full history, B gets confused or hits token limits. Evaluating only the final output makes it impossible to attribute the failure to the handoff. Inspecting the intermediate trace \(the handoff payload\) allows you to decouple A's summarization ability from B's execution ability.
