Frontend Visual QA

A rigorous visual QA protocol that audits already-rendered web, deck, dashboard, and Electron UIs with real-browser evidence and produces an evidence-backed defect report.

What it does

  • Audits the interface a user can actually see. Build success, DOM presence, and uninspected screenshot files count only as supporting signals, never as visual proof.
  • Forces a falsifiable audit contract first: target kind and canonical identity (URL, file hash, native artifact fingerprint), actor and job, conditional state (logged-out, empty, role-less, seeded), viewport matrix, design-system reference, and explicit authorization (audit-only vs fix-and-verify).
  • Ranks evidence A–D (real browser/native window, DevTools/E2E, headless sweep, static reasoning) and blocks promoting weak evidence into strong claims.
  • Ships scripts: scripts/visual_layout_audit.mjs (Playwright sweep for overflow, wrapping, media state, responsive widths) and scripts/silent_degradation_probe.mjs (font-never-shipped, renamed library classes, element crops).
  • Exercises real journeys — downloads, share/clipboard, file dialogs, print/PDF preview, Electron shell — then reports with severity (Blocker/Major/Moderate/Minor), crops, and an explicit "not verified" list.

Who it's for

  • Frontend developers doing pre-release visual review of web apps, landing pages, HTML decks, and admin dashboards.
  • Teams facing the "every gate is green but the page looks cheap" problem who need a detection method.
  • Electron/hybrid desktop developers verifying shell chrome, permissions, and file dialogs.
  • Leads who want consistent verified / partial / blocked QA reporting.

Examples

  1. "Audit the dashboard at localhost:5173 across desktop, tablet, and mobile" → prove the fixture state with --require, run the sweep, open every screenshot, then file findings.
  2. "Does deck.html clip text at 1920x1080 projection?" → run --file deck.html --page-type deck --viewport 1920x1080 and falsify apparent clipping against DOM geometry.
  3. "Verify the Export PDF button actually works" → trigger it in a real browser, confirm the print preview has non-blank pages, and mark anything unreachable as unverified.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/daymade/claude-code-skills/HEAD/frontend-visual-qa/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the frontend-visual-qa folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/frontend-visual-qa/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git && mkdir -p ~/.claude/skills && cp -r claude-code-skills/frontend-visual-qa ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/daymade/claude-code-skills.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy this skill only: cp -r claude-code-skills/frontend-visual-qa ~/.claude/skills/
  5. (Recommended) Check that the project you plan to audit already has Playwright; if not, the Level C mechanical sweep is skipped and only Level A/B evidence is used.
  6. Restart Claude Code, then ask something like "run a visual QA pass on this page".
  7. Run the bundled scripts from inside the audited project so they resolve its Playwright: node ~/.claude/skills/frontend-visual-qa/scripts/visual_layout_audit.mjs --help
