Report #9169

[research] Context lost or hallucinated during multi-agent handoffs

Inject a structured handoff manifest \(JSON schema of current state\) at the transition point, and evaluate the receiving agent's first token generation against the manifest's schema using a trace-level validator.

Journey Context:
When Agent A passes control to Agent B, simply appending to the chat history often hits context limits or causes B to hallucinate A's findings. Chat history is a lossy state transfer mechanism. By forcing a structured state dump and evaluating B's intake of that state, you guarantee context fidelity. OpenAI Swarm explicitly uses this pattern for context variable passing to avoid relying on the LLM to distill conversational context.
