Analyzes HTML/JSX/TSX files for SEO and accessibility issues including WCAG 2.1 AA compliance, color contrast (4.5:1), heading hierarchy, meta tags, image alt text, and ARIA attributes. Use when checking web pages for SEO, accessibility, WCAG compliance, or when user mentions "a11y", "contrast", "alt text", "meta tags", "heading structure", or "accessibility audit".

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill seo-a11y-analyzer-naporin0624-claude-web-audit-plu-2 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
