Control UI Use local browser automation to verify UI behavior with evidence. First reuse the repo's own Playwright, browser, or Electron harness if it exists; otherwise assemble a temporary local harness around the app's dev server or Chromium debug port. What It Is Used For Reproducing UI bugs that depend on real browser focus, keyboard input, scrolling, resizing, or rendering. Verifying visual or accessibility changes with screenshots and snapshots. Checking local web, IDE, or Electron behavior before shipping. Capturing console logs, network logs, CPU profiles, traces, or heap snapshots. Creating before/after evidence for verify-this. Pattern Start the app locally using the repo's documented dev command. Discover existing local harnesses: Playwright tests, Cypress specs, Storybook, browser scripts, Electron launch scripts, or snapshot tools. For a web app, connect to the local URL with the existing browser tooling.
