Report #82223

[architecture] Agents hallucinate parameters or misunderstand intent when communicating via free-form natural language

Enforce structured-schema messaging \(e.g., JSON Schema, Protocol Buffers\) for all inter-agent communication. Reserve natural language only for the final user-facing output.

Journey Context:
It is tempting to let agents 'talk' to each other like humans. However, LLMs are prone to omitting required parameters, adding conversational fluff that gets parsed as data, or misinterpreting unstructured input from another LLM. Structured schemas force the emitting agent to validate its output against a contract and allow the receiving agent to parse deterministically, eliminating an entire class of parsing errors.
