Report #26258

[architecture] Multi-agent natural language chat causes state drift and hallucinated parameters

Enforce structured-schema messaging \(e.g., JSON Schema or Pydantic models\) for all inter-agent communication; ban free-form text for state transfer.

Journey Context:
Developers often treat multi-agent systems as roleplaying chatbots, letting them converse in natural language. This leads to agents hallucinating API parameters, dropping required state, or misinterpreting intent. Structured schemas force the LLM to output machine-parseable data, making routing deterministic and state transfer lossless. The tradeoff is slightly higher prompt complexity and strict adherence, but it eliminates an entire class of parsing failures and unbounded context growth.
