How the WCAG Audit Patterns skill works

/wcag-audit-patterns

Comprehensive guide to auditing web content against WCAG 2.2 guidelines with actionable remediation strategies. This skill is for formal, criteria-mapped conformance work; for an informal accessibility pass on a design, use accessibility-review.

When to Use

  • Conducting accessibility audits
  • Fixing WCAG violations
  • Implementing accessible components
  • Preparing for accessibility litigation exposure
  • Meeting ADA/Section 508 requirements
  • Achieving VPAT compliance

Core Concepts

1. WCAG Conformance Levels

LevelDescriptionRequired For
AMinimum accessibilityLegal baseline
AAStandard conformanceMost regulations
AAAEnhanced accessibilitySpecialized needs

2. POUR Principles

Perceivable:    Can users perceive the content?
Operable:       Can users operate the interface?
Understandable: Can users understand the content?
Robust:         Does it work with assistive tech?

3. Common Violations by Impact

Critical (Blockers):
- Missing alt text for functional images
- No keyboard access to interactive elements
- Missing form labels
- Auto-playing media without controls

Serious:
- Insufficient color contrast
- Missing skip links
- Inaccessible custom widgets
- Missing page titles

Moderate:
- Missing language attribute
- Unclear link text
- Missing landmarks
- Improper heading hierarchy

Detailed Patterns and Worked Examples

Detailed pattern documentation (audit workflows, testing tooling, criterion-by-criterion checks, remediation code) lives in references/details.md. Read that file when the navigation tier above is insufficient.

Best Practices

Do's

  • Start early -- accessibility from the design phase
  • Test with real users -- disabled users provide the best feedback
  • Automate what you can -- 30-50% of issues are detectable automatically
  • Use semantic HTML -- reduces ARIA needs
  • Document patterns -- build an accessible component library

Don'ts

  • Don't rely only on automated testing -- manual testing is required
  • Don't use ARIA as the first solution -- native HTML first
  • Don't hide focus outlines -- keyboard users need them
  • Don't disable zoom -- users need to resize
  • Don't use color alone -- multiple indicators needed
