[architecture] Inter-agent communication failing due to unparseable free-form natural language messages

Enforce structured-schema messaging \(e.g., JSON Schema or Pydantic models\) for all inter-agent handoffs and tool calls, reserving natural language only for the final user-facing output.

Journey Context:
Developers often let agents chat in free-form text because LLMs are good at language. However, receiving agents frequently hallucinate missing fields or misparse intent from unstructured text, leading to cascading errors. Structured schemas force the emitting agent to output machine-validatable data, making the interface a strict contract. The tradeoff is slightly higher token cost and occasional generation failures for complex schemas, but this is far cheaper than debugging silent cascading misinterpretations.
