Visual Tests and Chrome Debugging (pointer)
DevTools features (network inspection, profiling, accessibility tree, console replay) are canonical at the Chrome team's MCP server:
ChromeDevTools/chrome-devtools-mcp— github.com/ChromeDevTools/chrome-devtools-mcp (Apache-2.0, maintained by the Google Chrome DevTools team). Configure in.mcp.jsonto give Claude Code direct programmatic access during a session.
This skill scopes to the manual-review checklist when using Claude Code's --chrome flag — what to look for, not how the API works.
Prerequisites
- Claude Code launched with
--chrome - "Claude in Chrome" extension v1.0.36+
- Google Chrome open (not Brave/Arc/Firefox; no headless mode; WSL unsupported)
Manual-review checklist
When asked to visually validate a page or flow:
- Page loads with no console error
- Layout correct (no overflow, no overlap, no z-index bug)
- Text readable (contrast meets WCAG AA — see
wcag-audit) - Images loaded (no broken sources, lazy-load completes)
- Links functional (no 404 in network panel)
- Forms submittable (validation triggers on bad input)
- Responsive OK across mobile/tablet/desktop breakpoints — see
qa-design(responsive category) - No network error (no 4xx/5xx unless intentional)
Expected output
Structured report:
- Screenshots/GIFs of issues
- List of console + network errors with source location
- Recommendations sorted by severity
- Overall verdict:
OK/Warnings/Errors
