Report #52833

[architecture] Agents communicating via unstructured natural language causing hallucinated state and dropped variables

Enforce strict JSON schemas \(e.g., Pydantic models\) for all inter-agent messages and handoffs. Use structured outputs for agent-to-agent communication, reserving free-form text only for the final user-facing output.

Journey Context:
When agents chat in plain text, they play a telephone game where critical state variables \(like order IDs, flags, or configurations\) are easily omitted or hallucinated in subsequent turns. Free-form text is high-token and low-signal for machines. By forcing agents to emit structured JSON upon handoff, the receiving agent gets a deterministic, machine-parseable state payload, preventing infinite loops of asking for missing parameters.
