[research] How to evaluate multi-agent handoffs and routing without just checking final output

Implement trace-level evals that score the routing decision and context passed at the handoff point independently of the downstream agent's execution. Use a labeled dataset of \(state, correct\_next\_agent\) pairs.

Journey Context:
Agents often fail because the router sends the task to the wrong sub-agent, or strips critical context during the handoff. If you only eval the final output, you miss the root cause and treat a routing failure as a downstream execution failure. By evaluating the handoff as a distinct classification/information-retrieval step, you can isolate and fix routing logic without modifying the sub-agents.
