Jev-cu splits computer-use automation into two jobs: Jev picks the element, the action, whether the task is done, and how risky the step is, purely from a text description of what's on screen, while Codex Computer Use reads the actual interface and carries the action out.
It installs as a skill into Codex, with a local policy gate that blocks sensitive operations, deleting, sending, paying, authorizing, uploading, entering a code, installing, or changing a system setting, unless confirmed, and runs in dry-run mode by default.
It ships with an offline evaluation against recorded accessibility snapshots, so the element-picking accuracy can be checked without spending on live Jev calls.
