AccessLint — Web Accessibility & WCAG Compliance Scanner

AccessLint scans codebases for WCAG 2.1 violations, missing ARIA attributes, color contrast issues, keyboard navigation problems, form accessibility failures, and semantic HTML anti-patterns. It uses regex-based pattern matching against 95+ accessibility patterns across HTML, JSX, Vue, and Svelte templates. Lefthook integration for git hooks, markdown accessibility reports with WCAG success criterion mapping.

Commands

Free Tier (No license required)

accesslint scan [file|directory]

One-shot accessibility scan of files or directories.

How to execute:

bash "<SKILL_DIR>/scripts/accesslint.sh" scan [target]

What it does:

1. Accepts a file path or directory (defaults to current directory)
2. Auto-detects file type from extensions (HTML, JSX, TSX, Vue, Svelte)
3. Finds all template/component files that contain markup
4. Runs 95+ accessibility patterns against each file
5. Calculates an accessibility score (0-100) per file and overall
6. Outputs findings with: file, line number, check ID, severity, WCAG criterion, description, recommendation
7. Exit code 0 if passing (score >= 70), exit code 1 if issues found
8. Free tier limited to 5 files per scan

Example usage scenarios:

• "Scan my code for accessibility issues" -> runs accesslint scan .
• "Check this component for WCAG violations" -> runs accesslint scan src/components/Button.tsx
• "Audit my templates for missing ARIA attributes" -> runs accesslint scan src/
• "Are there any accessibility problems in my frontend?" -> runs accesslint scan .

Pro Tier ($19/user/month -- requires ACCESSLINT_LICENSE_KEY)

accesslint hooks install

Install git pre-commit hooks that scan staged files for accessibility issues before every commit.

How to execute:

bash "<SKILL_DIR>/scripts/accesslint.sh" hooks install

What it does:

1. Validates Pro+ license
2. Copies lefthook config to project root
3. Installs lefthook pre-commit hook
4. On every commit: scans all staged template files for accessibility violations, blocks commit if critical/high findings, shows remediation advice

accesslint hooks uninstall

Remove AccessLint git hooks.

bash "<SKILL_DIR>/scripts/accesslint.sh" hooks uninstall

accesslint report [directory]

Generate a markdown accessibility report with findings, severity breakdown, and WCAG criterion mapping.

bash "<SKILL_DIR>/scripts/accesslint.sh" report [directory]

What it does:

1. Validates Pro+ license
2. Runs full scan of the directory
3. Generates a formatted markdown report from template
4. Includes per-file breakdowns, accessibility scores, WCAG 2.1 success criterion references
5. Output suitable for accessibility reviews and compliance audits

accesslint audit [directory]

Deep accessibility audit with component analysis and ARIA coverage checks.

bash "<SKILL_DIR>/scripts/accesslint.sh" audit [directory]

What it does:

1. Validates Pro+ license
2. Runs all 95+ patterns including framework-specific and dynamic content patterns
3. Analyzes component-level accessibility coverage
4. Reports ARIA attribute completeness across the codebase
5. Provides heading hierarchy and landmark region analysis

accesslint policy [directory]

Enforce organization-specific accessibility policies on codebases.

bash "<SKILL_DIR>/scripts/accesslint.sh" policy [directory]

What it does:

1. Validates Team+ license
2. Loads custom policies from ~/.openclaw/openclaw.json (accesslint.config.customPolicies)
3. Enforces organization-specific rules (e.g., required ARIA patterns, banned inaccessible patterns, mandatory alt text)
4. Combines custom policies with built-in patterns for comprehensive scanning
5. Outputs SARIF-compatible results

bash "<SKILL_DIR>/scripts/accesslint.sh" wcag [directory]

What it does:

1. Validates Team+ license
2. Runs full scan with all patterns
3. Maps findings to WCAG 2.1 success criteria (Level A, AA, AAA)
4. Generates comprehensive compliance report with pass/fail per criterion

accesslint status

Show license and configuration information.

bash "<SKILL_DIR>/scripts/accesslint.sh" status

Detected Violations

AccessLint detects 95+ accessibility patterns across 6 categories:

Configuration

Users can configure AccessLint in ~/.openclaw/openclaw.json:

{
  "skills": {
    "entries": {
      "accesslint": {
        "enabled": true,
        "apiKey": "YOUR_LICENSE_KEY_HERE",
        "config": {
          "severityThreshold": "high",
          "customPolicies": [],
          "excludePatterns": ["**/test/**", "**/examples/**", "**/storybook/**"],
          "wcagLevel": "AA",
          "reportFormat": "markdown"
        }
      }
    }
  }
}

Important Notes

• Free tier works immediately with no configuration
• All scanning happens locally -- no code is sent to external servers
• License validation is offline -- no phone-home or network calls
• Pattern matching only -- no AST parsing, no external dependencies
• Supports scanning multiple template formats in a single pass
• Git hooks use lefthook which must be installed (see install metadata above)
• Exit codes: 0 = passing (score >= 70), 1 = issues found (for CI/CD integration)
• Addresses WCAG 2.1 Level A, AA, and AAA success criteria

Error Handling

• If lefthook is not installed and user tries hooks install, prompt to install it
• If license key is invalid or expired, show clear message with link to https://accesslint.pages.dev/renew
• If a file is binary, skip it automatically with no warning
• If no scannable files found in target, report clean scan with info message
• If file type cannot be determined from extension, skip the file gracefully

The user might say things like:

• "Scan my code for accessibility issues"

• "Scan for keyboard navigation issues"
• "Check my React components for a11y issues"
• "Generate an accessibility report"
• "Set up pre-commit hooks for accessibility"
• "Check for missing alt text on images"
• "Are there any heading hierarchy problems?"
• "Scan for color contrast issues"
• "Run WCAG compliance checks on my templates"
