Report #71278

[architecture] Agents hallucinate parameters during inter-agent handoffs using free-form text

Use structured JSON schemas for agent-to-agent messaging, treating handoffs as internal API calls rather than chat messages.

Journey Context:
Free-form natural language seems flexible but causes parsing failures and hallucinated state in the receiving agent. Structured schemas enforce strict contracts, ensuring the receiving agent gets exactly the typed arguments it expects, just like a function call.
