Report #13365

[architecture] Agents communicating via free-form natural language suffer from parsing failures and hallucinated parameters

Enforce structured-schema messaging \(e.g., JSON Schema, Protocol Buffers\) for all inter-agent communication; reserve natural language strictly for human interaction.

Journey Context:
It is tempting to let LLMs talk to LLMs in plain English because they are language models. However, the receiving agent must parse this into function calls, leading to fragility. Structured schemas guarantee syntactic validity and make the interface contract explicit. The tradeoff is slightly higher prompt complexity to enforce the schema, but it eliminates an entire class of context-drifting parsing errors.
