[architecture] Agents hallucinating parameters when passing context via free-form natural language

Use structured-schema messaging \(e.g., JSON Schema or Pydantic models\) for all inter-agent communication, treating agent handoffs like API contracts.

Journey Context:
Developers often let agents chat in natural language because it is easy to prototype. However, LLMs routinely drop required fields, hallucinate values, or misinterpret intent when parsing free-text. Structured schemas force the LLM to generate valid, machine-readable payloads, making the system deterministic at the integration boundaries. This trades the flexibility of natural language for the reliability of API contracts, which is essential for production systems.
