Compare captures; stitch lazy/animated pages.
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
# Visual Regression Lab Use this skill to capture comparable browser evidence and inspect visual regressions. Scope routes, viewports and states to the requested comparison; a capture alone does not prove quality. ## Required Checks 1. Start or identify the local server. 2. Open the relevant route in a browser or Playwright. 3. Capture the relevant supported viewports and states, using the same conditions for baseline and candidate. 4. Check console errors, failed requests, layout overflow, missing media, and text clipping. 5. Inspect first viewport composition, hierarchy, spacing, typography, image crops, and CTA visibility. 6. Test key interactions: nav, forms, menus, tabs, accordions, hover states, focus states, and modals. 7. For animation-heavy work, test reduced-motion behavior and watch for jank. 8. For canvas/WebGL/video, verify nonblank rendered pixels and stable framing. 9. Report observed differences with evidence. Repair only when authorized, then recapture affected states; no fixed polish-pass or edit quota applies. …

How to install
mdr add thegoat395/codex-skills/visual-regression-lab@sha256:80e2e679c415ab35The line at the top of this page pins the label git:20260910.feff772, 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.
