Build or adapt a local browser/CDP harness to drive and inspect a web, IDE, or Electron UI. Use for local UI verification, screenshots, accessibility snapshots, perf profiles, visual diffs, or reproducing UI bugs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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`. ## Setup Pattern 1. Start the app locally using the repo's documented dev command. 2. Discover existing local harnesses: Playwright tests, Cypress specs, Storybook, browser scripts, Electron launch scripts, or snapshot tools. 3. For a web app, connect to the local URL with the existing browser tooling. 4. For Electron/Chromium, enable a remote debugging port when supported. 5. Select the correct page by stable app markers, not by tab order alone. …

How to install
mdr add asymmetric-al/core/control-ui@sha256:40775510557e07caThe line at the top of this page pins the label git:20260625.a8637f3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
