Report #10545

[architecture] Agents hallucinate parameters when parsing free-form natural language messages from other agents

Use structured schema \(JSON schema or Pydantic models\) for inter-agent messaging; reserve natural language only for user-facing outputs or unstructured context passing.

Journey Context:
LLMs are great at generating text but terrible at reliably extracting structured action parameters from paragraphs without schema enforcement. Free-form inter-agent communication leads to infinite loops of clarification or missing arguments. Structured schemas provide a strict contract between agents, ensuring machine-readable reliability while retaining natural language for human-readable summaries.
