Seven open-source Jev skills for Claude Code and Codex
The author open-sourced Jev Skills, which use Jev for model routing, skill selection, context picking, test prioritization, bug triage and plan comparison.
7 Jev skills you can reuse in Claude Code and Codex. I open-sourced Jev Skills for anyone building an AI coding harness with TypeSafe's Jev. The reusable pieces: 1. Model router: suggest the smallest suitable model from your available options. 2. Skill picker: find the relevant skill in your installed catalog. 3. Context picker: choose which file or excerpt to inspect next. 4. Test prioritizer: pick the first test to run. 5. Bug triage: suggest where to start investigating. 6. Plan selector: compare implementation plans. 7. Controls: turn routing on or off and check usage. You supply the candidates. Jev recommends one. Your coding agent still handles execution and permissions. The repo includes a shared CLI, example inputs, 36 passing tests and live eval results, including the misses. In 22 synthetic API calls, 5 decisions fell back below 60% confidence. Automatic workflows start OFF. MIT-licensed.
