Report #27607

[frontier] Using a massive LLM to route simple user intents or classify tool calls causes high latency and cost

Implement a semantic router using fast, local embeddings to match intents to agent skills or tool clusters before invoking the heavy LLM.

Journey Context:
In multi-agent systems, every user message often goes straight to GPT-4 or Claude to decide which agent or tool to use. This adds 500ms\+ and costs cents per turn. By pre-computing embeddings for agent skill descriptions and using a fast vector similarity search to route the query, you only invoke the heavy LLM for the actual task execution, cutting routing latency to under 50ms and cost to near zero.
