Report #12264
[architecture] Agents communicating via free-form natural language causing hallucinated state changes
Use structured JSON schemas for inter-agent communication \(tool calls/functions\). Reserve natural language only for the final user-facing output or summarization.
Journey Context:
It is tempting to let agents 'talk' to each other via natural language because LLMs are good at it. However, NL is lossy and ambiguous. Agent B will frequently hallucinate parameters or misunderstand Agent A's intent. By forcing agents to communicate via structured function calls \(JSON schemas\), you enforce a strict API contract between them, making the system deterministic, debuggable, and immune to inter-agent hallucination.
