Report #63523

[architecture] Agents failing to parse each other's outputs due to free-form natural language messaging

Enforce structured JSON schemas for all inter-agent communication instead of passing raw conversational text.

Journey Context:
LLMs generate verbose, unpredictable text. Passing this between agents causes hallucination cascades and parsing failures. JSON schema forces deterministic field extraction and allows the receiving agent to programmatically validate inputs before acting, treating the multi-agent system as a distributed microservices architecture rather than a chat room.
