Claude Accessibility Audit Skill: Automated WCAG Audits with AI

A full-featured WCAG 2.1/2.2 web accessibility audit skill for Claude — by Anish.

Audit any public website for accessibility barriers, get per-page findings mapped to WCAG success criteria, and receive technology-specific fix code — all delivered as a polished downloadable Word (.docx) and PDF report.

What It Does

  • 🔍 Crawls your entire site — not just the homepage
  • 🧠 Detects your tech stack automatically (React, Next.js, Vue, Angular, WordPress, Shopify, Vanilla HTML, and more)
  • 📋 Checks every WCAG 2.1/2.2 criterion assessable from HTML across all four POUR principles
  • 🎯 Maps issues per page with WCAG criterion, level (A/AA/AAA), severity, affected users, and fix complexity
  • 🛠️ Provides stack-specific fix code — JSX for React, Liquid for Shopify, PHP templates for WordPress, etc.
  • 📄 Generates a professional report — cover page, executive summary, per-page findings, priority roadmap, automated testing guide
  • ⚖️ Notes legal context — ADA Title III, Section 508, EN 301 549

Report Sections

  • Cover Page — Site name, severity counts at a glance
  • Executive Summary — Compliance verdict, POUR scores, affected user groups
  • Pages Audited — All crawled URLs with issue count and highest severity
  • Detailed Findings — Per-page issue tables + fix code blocks for every Critical/Serious issue
  • WCAG Criterion Reference — Every issue mapped to its criterion, sorted by level
  • Priority Fix Roadmap — Sprint 1 (Critical) → Sprint 2 (Serious) → Sprint 3 (Backlog)

Why It Matters

Accessibility isn’t optional — it’s a legal requirement and an ethical responsibility. With over 1 billion people worldwide living with disabilities, an inaccessible website excludes a significant portion of your potential audience.

This skill removes the friction of running a thorough audit. Point Claude at a URL and get back an enterprise-grade report with prioritized, framework-specific fixes ready to drop into your codebase.

Built for Developers

Unlike generic auditors that dump a list of issues, this skill:

  • Understands your stack and writes fixes in your language
  • Prioritizes work into achievable sprints
  • Explains who each issue affects and why it matters
  • Pairs every finding with the relevant WCAG criterion
