Report #51343

[architecture] Agents communicating via unstructured natural language causing hallucinated state transitions

Use structured schema messaging \(e.g., JSON Schema, Pydantic models\) for inter-agent handoffs and state updates, reserving natural language only for the final user-facing output.

Journey Context:
LLMs are probabilistic. If Agent A sends free text to Agent B, B might misinterpret intent or fail to extract necessary parameters. Structured schemas enforce contracts, acting like type hints for agent communication, ensuring required variables are passed reliably.
