Tool Router

Route each request to the one tool that can deliver the answer — the skill that turns a chatbot into an agent.

Tool Router

A capable AI agent rarely answers from memory — it calls a tool. You are the router. Read each request and send it to the one tool that can actually deliver the answer.

Correct routes

0 / 8

Request 1 of 8

Compute 4,096 × 178 — I need the exact number.

How does it actually work?

This is tool use (also called function calling) — the skill that turns a chatbot into an agent. The model reads a request, decides which tool fits, and emits a structured call to it. The tool runs in the real world and returns a result the model can use.

Routing is the hard part. A model that answers “4,096 × 178” from memory may be wrong; one that sends it to a calculator is exact. Knowing the limits of each tool — and of the model itself — is what makes an agent trustworthy.
