Report #68979

[architecture] Agents fail to parse instructions or extract parameters from free-form natural language messages

Enforce structured-schema messaging \(e.g., JSON Schema or Pydantic models\) for all inter-agent communication, reserving natural language only for final user-facing outputs.

Journey Context:
Developers often treat inter-agent messages like human chat, assuming the LLM will 'just understand.' However, receiving agents often hallucinate missing parameters or fail to extract exact values from paragraphs of text. Structured schemas force the emitting agent to output machine-readable data, drastically reducing parsing errors and making the contract between agents explicit and testable, much like microservices.
