Use when auditing accessibility, fixing a11y violations, checking color contrast, generating compliance reports, or integrating accessibility checks into CI/CD pipelines.\"\n---\n\n# Accessibility Audit\n\nWCAG 2.2 Accessibility Audit and Remediation Skill\n\n## Description\n\nThe a11y-audit skill provides a complete accessibility audit pipeline for modern web applications. It implements a three-phase workflow -- Scan, Fix, Verify -- that identifies WCAG 2.2 Level A and AA violations, generates exact fix code per framework, and produces stakeholder-ready compliance reports.\n\nFor every violation it finds, it provides the precise before/after code fix tailored to your framework (React, Next.js, Vue, Angular, Svelte, or plain HTML).\n\n**What this skill does:**\n\n1. **Scans** your codebase for every WCAG 2.2 Level A and AA violation, categorized by severity (Critical, Major, Minor)\n2. **Fixes** each violation with framework-specific before/after code patterns\n3. **Verifies** that fixes resolve the original violations and introduces no regressions\n4. **Reports** findings in a structured format suitable for developers, PMs, and compliance stakeholders\n5. **Integrates** into CI/CD pipelines to prevent accessibility regressions\n\n## Features\n\n| Feature | Description |\n|---------|-------------|\n| **Full WCAG 2.2 Scan** | Checks all Level A and AA success criteria across your codebase |\n| **Framework Detection** | Auto-detects React, Next.js, Vue, Angular, Svelte, or plain HTML |\n| **Severity Classification** | Categorizes each violation as Critical, Major, or Minor |\n| **Fix Code Generation** | Produces before/after code diffs for every issue |\n| **Color Contrast Checker** | Validates foreground/background pairs against AA and AAA ratios |\n| **Compliance Reporting** | Generates stakeholder reports with pass/fail summaries |\n| **CI/CD Integration** | GitHub Actions, GitLab CI, Azure DevOps pipeline configs |\n| **Keyboard Navigation Audit** | Detects missing focus management and tab order issues |\n| **ARIA Validation** | Checks for incorrect, redundant, or missing ARIA attributes |\n\n### Severity Definitions\n\n| Severity | Definition | Example | SLA |\n|----------|-----------|---------|-----|\n| **Critical** | Blocks access for entire user groups | Missing alt text, no keyboard access to navigation | Fix before release |\n| **Major** | Significant barrier that degrades experience | Insufficient color contrast, missing form labels | Fix within current sprint |\n| **Minor** | Usability issue that causes friction | Redundant ARIA roles, suboptimal heading hierarchy | Fix within next 2 sprints |\n\n## Usage\n\n### Quick Start\n\n```bash\n# Scan entire project\npython scripts/a11y_scanner.py /path/to/project\n\n# Scan with JSON output for tooling\npython scripts/a11y_scanner.py /path/to/project --json\n\n# Check color contrast for specific values\npython scripts/contrast_checker.py --fg \"#777777\" --bg \"#ffffff\"\n\n# Check contrast across a CSS/Tailwind file\npython scripts/contrast_checker.py --file /path/to/styles.css\n```\n\n### Slash Command\n\n```\n/a11y-audit # Audit current project\n/a11y-audit --scope src/ # Audit specific directory\n/a11y-audit --fix # Audit and auto-apply fixes\n/a11y-audit --report # Generate stakeholder report\n/a11y-audit --ci # Output CI-compatible results\n```\n\n### Three-Phase Workflow\n\n**Phase 1: Scan** -- Walk the source tree, detect framework, apply rule set.\n\n```bash\npython scripts/a11y_scanner.py /path/to/project --format table\n```\n\n**Phase 2: Fix** -- Apply framework-specific fixes for each violation.\n\n> See [references/framework-a11y-patterns.md](references/framework-a11y-patterns.md) for the complete fix patterns catalog.\n\n**Phase 3: Verify** -- Re-run the scanner to confirm fixes and check for regressions.\n\n```bash\npython scripts/a11y_scanner.py /path/to/project --baseline audit-baseline.json\n```\n\n## Example: React Component Audit\n\n```tsx\n// BEFORE: src/components/ProductCard.tsx\nfunction ProductCard({ product }) {\n return (\n
navigate(`/product/${product.id}`)}>\n \n
{product.name}
\n ${product.price}\n
\n );\n}\n```\n\n| # | WCAG | Severity | Issue |\n|---|------|----------|-------|\n| 1 | 1.1.1 | Critical | `` missing `alt` attribute |\n| 2 | 2.1.1 | Critical | `
` not keyboard accessible |\n| 3 | 1.4.3 | Major | Color `#aaa` on white fails contrast (2.32:1, needs 4.5:1) |\n| 4 | 1.4.3 | Major | Color `#999` on white fails contrast (2.85:1, needs 4.5:1) |\n| 5 | 4.1.2 | Major | Interactive element missing role and accessible name |\n\n```tsx\n// AFTER: src/components/ProductCard.tsx\nfunction ProductCard({ product }) {\n return (\n \n {product.imageAlt\n
{product.name}
\n ${product.price}\n \n );\n}\n```\n\n> See [references/examples-by-framework.md](references/examples-by-framework.md) for Vue, Angular, Next.js, and Svelte examples.\n\n## Tools Reference\n\n### a11y_scanner.py\n\n```\nUsage: python scripts/a11y_scanner.py [options]\n\nOptions:\n --json Output results as JSON\n --format {table,csv} Output format (default: table)\n --severity {critical,major,minor} Filter by minimum severity\n --framework {react,vue,angular,svelte,html,auto} Force framework (default: auto)\n --baseline FILE Compare against previous scan results\n --report Generate stakeholder report\n --output FILE Write results to file\n --quiet Suppress output, exit code only\n --ci CI mode: non-zero exit on critical issues\n```\n\n### contrast_checker.py\n\n```\nUsage: python scripts/contrast_checker.py [options]\n\nOptions:\n --fg COLOR Foreground color (hex)\n --bg COLOR Background color (hex)\n --file FILE Scan CSS file for color pairs\n --tailwind DIR Scan directory for Tailwind color classes\n --json Output results as JSON\n --suggest Suggest accessible alternatives for failures\n --level {aa,aaa} Target conformance level (default: aa)\n```\n\n## Common Pitfalls\n\n| Pitfall | Correct Approach |\n|---------|------------------|\n| `role=\"button\"` on a `
