Report #37840

[architecture] Agents passing context via unstructured natural language leads to hallucination and parsing failures between agents

Use structured schema messaging \(JSON/Pydantic\) for inter-agent communication; reserve natural language strictly for user-facing boundaries.

Journey Context:
LLMs are bad at extracting precise state from paragraphs. Free-form text causes cascading parsing errors as one agent's verbose output becomes another's noisy input. Tradeoff: structured schemas are rigid and harder to debug by reading raw logs, but they guarantee state integrity and prevent cascading extraction failures.
