Web Design Reviewer
Use this skill for visual QA and source-level fixes after a page is already running. This is not the right skill for functional automation or regression suites.
Activation Conditions
- Reviewing a live page for layout or spacing defects
- Checking responsive behavior at a few critical widths
- Comparing a page to a design system or visual target
- Tracing a visible issue back to CSS, Tailwind classes, or component structure
Recommended Workflow
- Open the page with a browser-capable MCP client such as Playwright MCP.
- Capture the current state before editing.
- Test desktop and mobile widths.
- Fix the source code, then re-check the same viewports.

Review Checklist
- No overflow or clipped content at target widths
- Interactive controls remain visible and reachable
- Text contrast and focus states are acceptable
- Repeated components use consistent spacing, typography, and color
- Fixes were verified visually after the code change

Cross-Client Portability
This skill is written to stay usable across GitHub Copilot, Claude Code, Codex, and Gemini CLI.
- GitHub Copilot: keep the folder in a Copilot-visible skill or plugin path, or wrap the workflow as project instructions if the host does not support portable skill folders directly.
- Claude Code: keep the folder in a local skills directory or a compatible plugin or marketplace source.
- Codex: install or sync the folder into
$CODEX_HOME/skills/<skill-name>and restart Codex after major changes. - Gemini CLI: this repository generates a project command named
/skills:web-design-reviewerfrom this skill. Rebuild commands withpython scripts/export-gemini-skill.py web-design-reviewerand then run/commands reloadinside Gemini CLI.
MCP Availability And Fallback
Preferred MCP servers for this skill:
Playwright MCP(primary)Chrome DevTools MCP (optional)(primary)
If MCP is unavailable in the current host:
- Use Playwright CLI, browser devtools, screenshots, and manual responsive checks when MCP browser tools are unavailable.
- Capture console or network issues with the browser or terminal before proposing visual fixes.
