What it is
A standalone Cloudflare-targeted Flue example in TypeScript that routes a support agent's work. It is for developers exploring Flue agents on Cloudflare Workers who want typed routing decisions from Jev alongside a chat model.
How it uses Jev
useJevRouter() turns a typed question map into a validated route_with_jev Flue tool. The agent calls it with the user's request as state; Jev returns structured choices, probabilities, and confidence, which the agent reports as selected team, urgency, confidence, and Jev model.

Technique worth stealing
Wrap a typed question map into a validated Flue tool so Jev returns structured routing decisions without acting as the chat model.
Try it
cd flue-jev-demo && pnpm install && pnpm dev; run pnpm demo for one Jev request.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
