[frontier] How do I route between agents in a multi-agent system without brittle prompt parsing?

Implement handoffs using strict structured output \(JSON Schema\) where the active agent outputs a 'handoff\_to' field with target agent name and state payload, parsed deterministically as a tool call.

Journey Context:
Naive implementations parse 'I will hand off to Agent X' from natural language, which fails with creative models or edge cases. LangGraph's graph nodes are powerful but heavy for simple handoffs. The Swarm pattern demonstrates that treating handoffs as function calls \(structured outputs\) is more robust. The agent calls a 'transfer\_to\_agent\_X' function with context. This is deterministic, supports type checking via Pydantic, and integrates with existing function-calling infrastructure. Define handoff tools with clear schemas and handle them in your orchestration loop.
