Report #68753

[research] Multi-agent system produces correct final answer but takes redundant steps or loops between agents

Evaluate the trajectory \(the sequence of tool calls and agent handoffs\), not just the final state. Use a lightweight LLM-as-a-judge to score the context-passing efficiency at each handoff boundary.

Journey Context:
If you only eval the final output, agents can loop infinitely or pass huge, irrelevant context between themselves, bloating token costs and latency. Trajectory evals catch inefficient handoffs. You must score the intermediate steps to ensure the agent isn't accidentally right after 10 retries.
