Usage

/accessibility-review $ARGUMENTS

Audit for accessibility: @$1

WCAG 2.1 AA Quick Reference

Perceivable

1.1.1 Non-text content has alt text

1.3.1 Info and structure conveyed semantically

1.4.3 Contrast ratio >= 4.5:1 (normal text), >= 3:1 (large text)

1.4.11 Non-text contrast >= 3:1 (UI components, graphics)

Operable

2.1.1 All functionality available via keyboard

2.4.3 Logical focus order

2.4.7 Visible focus indicator

2.5.5 Touch target >= 44x44 CSS pixels

Understandable

3.2.1 Predictable on focus (no unexpected changes)

3.3.1 Error identification (describe the error)

3.3.2 Labels or instructions for inputs

Robust

4.1.2 Name, role, value for all UI components

Common Issues

Insufficient color contrast

Missing form labels

No keyboard access to interactive elements

Missing alt text on meaningful images

Focus traps in modals

Missing ARIA landmarks

Auto-playing media without controls

Time limits without extension options

Testing Approach

Automated scan (catches ~30% of issues)

Keyboard-only navigation

Screen reader testing (VoiceOver, NVDA)

Color contrast verification

Zoom to 200% — does layout break?

2. **[Major fix]** — Improves [what] for [who]

3. **[Minor fix]** — Nice to have

If Connectors Available

If ~~design tool is connected:

Inspect color values, font sizes, and touch targets directly from Figma

Check component ARIA roles and keyboard behavior in the design spec

If ~~project tracker is connected:

Create tickets for each accessibility finding with severity and WCAG criterion

Link findings to existing accessibility remediation epics

Tips

Start with contrast and keyboard — These catch the most common and impactful issues.

Test with real assistive technology — My audit is a great start, but manual testing with VoiceOver/NVDA catches things I can't.

Prioritize by impact — Fix issues that block users first, polish later.
