Report #27437

[architecture] Agents communicating via unstructured natural language causing hallucination cascades and missed parameters

Enforce structured-schema \(JSON/Pydantic\) messaging for inter-agent communication; reserve natural language only for the final user-facing output.

Journey Context:
LLMs are generative. If Agent A sends free-form text to Agent B, B might hallucinate constraints or miss required parameters. Structured schemas act as a strict contract, forcing A to provide exact fields and B to parse them deterministically. This eliminates an entire class of parsing errors and ensures state is passed cleanly without information loss.
