Report #10750

[research] Multi-agent handoffs lose critical context or mutate data formats, causing downstream agents to hallucinate

Implement inter-agent schema validation and context-window evals at the exact handoff boundary. Log the full payload passed between agents and assert the presence of required keys and context relevance.

Journey Context:
In multi-agent systems, Agent A passes a JSON payload or string to Agent B. If Agent A omits a key or adds noise, Agent B will hallucinate to fill the gap or crash. End-to-end evals won't tell you which agent failed. By validating schemas \(e.g., Pydantic\) and evaluating the context relevance at the handoff edge, you isolate the failure to the specific agent and prevent cascading errors.
