[research] Multi-agent handoffs lose critical context or hallucinate state

Inject a structured state schema \(e.g., JSON schema or Pydantic model\) at the handoff boundary and evaluate the handoff payload independently. Do not rely solely on the raw text context window for state transfer.

Journey Context:
When Agent A hands off to Agent B, developers often just pass the chat history. Agent B then hallucinates details or loses specific variables. By forcing a structured state payload at the handoff, you make the context machine-readable and verifiable. You can write unit tests against the handoff payload itself to ensure no state is dropped before Agent B even starts.
