The README opens with

Jev is TypeSafe's System One decision model. It answers a question in roughly 70 to 500 ms with a typed answer and a confidence score. This repo connects Jev to coding agents so they can ask it which skill to load, which tools a step needs, and how to move in the browser.

For the reasoning behind the design, including where Jev wins and where it loses, see When Jev wins.

This project is fully experimental. Do not use it in important or production-grade projects.
