[frontier] How to route tasks to specialized agents deterministically without LLM latency and non-determinism in the router
Use constrained generation \(Outlines or Guidance\) to force the LLM to output routing decisions as structured JSON with agent IDs from a predefined enum, making routing a single token generation with guaranteed schema compliance
Journey Context:
Previous approaches used separate LLM calls for routing \(which agent should handle this?\), adding 500ms\+ latency and suffering from temperature-induced inconsistency. New pattern uses grammar-constrained decoding to force the first tokens to be a valid agent ID from a predefined set, making routing deterministic, fast, and parseable without regex validation.
