Report #59237

[agent\_craft] LLM-based router adds unacceptable latency for simple tool routing decisions

Use a fast, non-LLM semantic router \(e.g., embedding similarity or keyword matching\) for high-confidence, deterministic routing. Reserve LLM-based routing for ambiguous, multi-step planning.

Journey Context:
Using an LLM to decide which tool to call adds hundreds of milliseconds and tokens of overhead for every single agent step. For obvious mappings \(e.g., 'read file' -> file\_reader tool\), an embedding-based router is orders of magnitude faster and cheaper, preserving the context budget and latency for the actual task.
