Jev Computer Use

Codex skill that lets Jev pick the next UI element from text candidates while Computer Use reads the screen and executes — text only, no screenshots.

Sac-Y open-sourced a Codex Computer Use loop where Jev (TypeSafe System One) chooses the next element, action, completion, and risk from accessibility text — Codex reads the UI and executes, with local policy gates on sensitive actions.

Only text candidates are sent to Jev; screenshots stay out of the loop.

Install

git clone https://github.com/Sac-Y/Jev-cu
cd Jev-cu
npm run install-skill   # copies skill to ~/.codex/skills/jev-use

Set TYPESAFE_API_KEY in .env.local, then run tasks inside Codex desktop cua_repl with scripts/loop.mjs.

Safety

  • Default dry-run; delete, send, pay, auth, upload, captcha, install, and system settings stop at confirm.
  • App allowlist lives in scripts/policy.mjs.
