Report #45647
[architecture] Inter-agent communication fails due to unparseable natural language responses
Enforce structured JSON schema \(e.g., Pydantic models or tool call schemas\) for all agent-to-agent messages, treating inter-agent communication as tool invocation rather than free-form chat.
Journey Context:
Developers often let agents chat via natural language because it feels flexible. However, LLMs frequently omit required parameters, hallucinate formats, or add conversational filler that breaks the receiving agent's parser. By forcing communication through strict function-calling interfaces \(tool calls\), you leverage the LLM's native structured output capabilities, eliminating parsing failures and making the contract between agents machine-readable.
