Report #57197

[architecture] Agents failing to parse parameters or hallucinating data during inter-agent handoffs

Enforce strict JSON schemas for all inter-agent messages and function calls. Reserve natural language strictly for user-facing outputs.

Journey Context:
When agents communicate via free-form text, the receiving agent often misses key variables or hallucinates missing parameters due to conversational filler. By enforcing structured outputs \(JSON schemas\) for handoffs, the emitting agent is constrained to output machine-readable data, making the receiving agent's parsing deterministic. The tradeoff is a slightly higher token cost for schema enforcement and less flexibility, but reliability in agent-to-agent communication skyrockets.
