Report #55757

[architecture] Agents failing to parse instructions from other agents due to free-form text hallucination

Enforce structured JSON schemas for all inter-agent messages, treating natural language as a payload field rather than the message envelope.

Journey Context:
Developers often let agents chat in natural language because LLMs excel at it. However, free-form inter-agent communication leads to infinite loops, missed arguments, and hallucinated function calls. By defining a strict schema \(e.g., separating routing headers from the natural language payload\), you decouple orchestration from reasoning, making the system deterministic at the routing layer while keeping the LLM flexible within the payload.
