[frontier] Natural language communication between agents loses state and introduces ambiguity during handoffs

Use structured outputs \(JSON schemas\) for all inter-agent communication. Define explicit schemas for handoff messages that include task status, decisions made with rationale, pending actions, and relevant context keys. Validate handoff messages against schemas before processing.

Journey Context:
When agents communicate via natural language, information is lost in translation. The receiving agent must parse and interpret free text, which is lossy and unreliable. Structured outputs create a typed contract between agents—like an API contract between microservices. The overhead of defining schemas pays off in reliability, debuggability, and the ability to validate handoffs automatically. Common mistake: using structured outputs for tool calls but natural language for agent-to-agent communication. Both should be structured. The key tradeoff is that structured communication is less flexible—schemas must be defined and maintained—but for production systems, reliability trumps flexibility. This pattern is just beginning to replace ad-hoc natural language handoffs in production multi-agent systems.
