Report #83522

[architecture] Inter-agent handoffs fail due to hallucinated or missing parameters in natural language messages

Enforce structured JSON schemas \(e.g., Pydantic models or OpenAI function schemas\) for all inter-agent communication and handoffs, treating agent interactions like API contracts.

Journey Context:
Developers often let agents chat via free-form text because it mimics human teams. However, LLMs are unreliable at extracting exact parameters from paragraphs, leading to cascading TypeErrors or missing data down the chain. Structured schemas force the emitting agent to output machine-parseable data, drastically reducing parsing failures at the receiving agent's entry point.
