Flue agent routing with TypeSafe Jev via Cloudflare AI Gateway

Automated README summary

Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

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.

Primitives:choicenoul

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.

Model judgments from README excerpts

Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence

These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
