Report #15616

[architecture] Agents failing to parse instructions or state updates from other agents due to free-form natural language messages

Enforce structured-schema messaging \(e.g., JSON Schema, Pydantic models\) for all inter-agent communication and state mutations, rejecting any message that fails validation.

Journey Context:
LLMs default to conversational text, but free-form chat between agents leads to hallucinated parameters, missing fields, and cascading parsing failures in downstream agents. Prompting for formats is fragile. Enforcing structured output guarantees the receiver gets exactly the fields it needs, making routing and state updates deterministic and debuggable.
