Visual Regression Lab

Use this skill to prove the site looks right in a browser, not just in code.

Required Checks

  • Start or identify the local server.
  • Open the relevant route in a browser or Playwright.
  • Capture desktop and mobile screenshots.
  • Check console errors, failed requests, layout overflow, missing media, and text clipping.
  • Inspect first viewport composition, hierarchy, spacing, typography, image crops, and CTA visibility.
  • Test key interactions: nav, forms, menus, tabs, accordions, hover states, focus states, and modals.
  • For animation-heavy work, test reduced-motion behavior and watch for jank.
  • For canvas/WebGL/video, verify nonblank rendered pixels and stable framing.
  • Do one second-pass polish edit when the result feels generic or cramped.

Output

Report:

  • routes/viewports checked
  • screenshots or saved paths when available
  • issues found and fixed
  • commands run
  • anything not tested

How to use it

Copy the folder

Take thegoat395/visual-regression-lab from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
