# Visual Tests and Chrome Debugging (pointer)

DevTools features (network inspection, profiling, accessibility tree, console replay) are canonical at the Chrome team's [`ChromeDevTools/chrome-devtools-mcp`](https://github.com/ChromeDevTools/chrome-devtools-mcp) (Apache-2.0). Since 2026 it ships **seven skills** next to its MCP server: `chrome-devtools`, `chrome-devtools-cli`, `a11y-debugging`, `debug-optimize-lcp`, `memory-leak-debugging`, `cookie-debugging`, `troubleshooting`.

```bash
# The plugin bundles the skills and the MCP server. The marketplace follows the vendor's default
# branch: what you get is the plugin.json there (chrome-devtools-mcp@1.10.1 on 2026-10-04).
/plugin marketplace add ChromeDevTools/chrome-devtools-mcp
/plugin install chrome-devtools-mcp@chrome-devtools-plugins
# MCP server only, pinned by us (the vendor's docs show @latest)
claude mcp add chrome-devtools --scope user npx chrome-devtools-mcp@1.10.1
```

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`
