[research] How to evaluate multi-agent handoffs and trace failures in complex workflows

Implement span-level evaluations for agent handoffs. Instead of only evaluating the final output, score each handoff event \(e.g., tool call, context passed to next agent\) on context fidelity and goal alignment. Use a lightweight LLM-as-a-judge or deterministic check at every boundary.

Journey Context:
Agents often fail silently because the context passed during a handoff loses critical information or introduces hallucinations. Evaluating only the final output makes debugging a nightmare because you don't know which agent introduced the error. By adding evals at the span/handoff level, you can pinpoint exactly where the context degradation occurred, reducing debugging time from hours to minutes.
