Report #30199

[architecture] Agents failing to parse each other's outputs due to conversational filler in inter-agent messages

Enforce structured JSON schemas \(e.g., Pydantic models\) for all agent-to-agent communication. Reserve natural language exclusively for the final user-facing output.

Journey Context:
LLMs default to conversational outputs \(e.g., 'Sure, here is the data you requested: ...'\). When another agent parses this, the conversational filler introduces ambiguity and extraction errors. Structured schemas force the LLM to output exact fields, making routing deterministic and state extraction reliable. Free-form text is for humans; structured data is for machines.
