Report #56266

[research] Context loss or mutation during multi-agent handoffs leading to compounding errors

Inject trace-level evals at handoff boundaries using an LLM-as-a-judge to verify that the exact task context and constraints are preserved in the passed message payload.

Journey Context:
When Agent A hands off to Agent B, it typically summarizes or passes a truncated context. B then operates on incomplete info, causing subtle failures. Standard end-to-end evals miss where the context was lost. By evaluating the intermediate message payload at the handoff span, you can isolate whether the failure was due to A's poor summarization or B's poor execution.
