control-ui
Build or adapt a local browser/CDP harness to drive and inspect a web, IDE
by cursorFree
Description
control-ui is an agent skill from Cursor's plugins collection for building or adapting a local browser harness that drives and inspects a web, IDE or Electron user interface through the Chrome DevTools Protocol. It is used to verify UI behaviour with evidence rather than by eye: reproducing bugs that depend on real browser focus, keyboard input, scrolling, resizing or rendering; checking visual or accessibility changes with screenshots and snapshots; checking local web, IDE or Electron behaviour before shipping; capturing console logs, network logs, CPU profiles, traces and heap snapshots; and creating before-and-after evidence for a verification step. The skill's first step is to reuse the repository's own Playwright, browser or Electron harness if it has one. Otherwise, it assembles a temporary harness around the application's development server or a Chromium debugging port. It has a setup pattern section for doing so. The approach suits front-end developers and anyone working on an Electron or IDE-style application who needs proof that a change works in the real interface. It is listed on skills.sh, where the page shows install counts and GitHub stars for the Cursor plugins repository, and its security audits all pass. Install it with npx skills add https://github.com/cursor/plugins --skill control-ui.…
