Report #17494

[architecture] Agents fail to parse state updates from other agents due to free-form natural language messaging

Enforce structured JSON schemas for all inter-agent communication and validate payloads before routing to the receiving agent.

Journey Context:
While LLMs understand natural language, using it as the transport layer between agents causes cascading parsing failures. An LLM might add conversational filler or omit a required parameter, causing the receiving agent to hallucinate the missing value or crash. Structured schemas act as a rigid contract, forcing the sending agent to output machine-parseable state, shifting the LLM from open-ended chat to deterministic data extraction.
