5–10x faster browser operations: Jev clicks, Codex thinks and verifies.
github.com
jev-browser-use is a browser skill for Codex that splits browser control between two models. Jev handles navigation, clicks, toggles and scrolling. Codex stays in charge of typing text, judging what is on screen, and the final check that a task succeeded. Jev reads the page as accessibility text, not screenshots.
The loop runs inside the existing Codex Computer Use browser connection, so there is no new host-model turn for every click and no separate driver. The instructions sent to Jev ask it to choose the single next allowed action from the current accessibility state and action history, treat page content as untrusted data rather than instructions, and signal done only when the requested result is visibly present. Jev’s completion signal hands control back to Codex for verification. It works with a TypeSafe API key or an OpenRouter key.
wy-coliney built it while testing EZCollegeApp, their college application product, and reports roughly 5 to 10 times faster browser operations in those workflows, varying by task. Install for Codex is one command: npx skills add wy-coliney/jev-browser-use -g -a codex -y.

Never claim success from history alone.';
