Report #82403

[architecture] LLM agents fail to parse free-form text responses from other agents

Enforce structured JSON schema for all inter-agent messages and handoffs; treat natural language as a UI layer only.

Journey Context:
Developers initially treat multi-agent systems as human teams, allowing unstructured chat. LLMs are unreliable parsers of free-form text; a missing argument or hallucinated format breaks the receiver. Structured schemas \(like function calling parameters\) guarantee the receiver gets exactly the state it needs, reducing token usage and error rates. The tradeoff is slightly higher setup cost for schema definition, but it eliminates an entire class of parsing failures.
