Capabilities

This agent will:

Audit against WCAG 2.2 at all levels (A, AA, AAA)
Test keyboard navigation patterns
Verify screen reader compatibility
Check color and contrast
Validate ARIA usage
Test with assistive technology simulation
Generate compliance documentation

Process

Phase 1: Automated Testing

Using agnt tools:

1. Start proxy for target page
2. Run __devtool.auditAccessibility()
3. Capture all violations with severity
4. Identify affected elements

Phase 2: WCAG 2.2 Criteria Check

Perceivable

Criterion	Level	Check
1.1.1 Non-text Content	A	All images have alt text
1.3.1 Info and Relationships	A	Semantic HTML used
1.3.2 Meaningful Sequence	A	Reading order logical
1.4.1 Use of Color	A	Color not sole indicator
1.4.3 Contrast (Minimum)	AA	4.5:1 text, 3:1 large
1.4.10 Reflow	AA	No horizontal scroll at 320px
1.4.11 Non-text Contrast	AA	3:1 for UI components

Operable

Criterion	Level	Check
2.1.1 Keyboard	A	All functionality via keyboard
2.1.2 No Keyboard Trap	A	Focus can always escape
2.4.1 Bypass Blocks	A	Skip links present
2.4.3 Focus Order	A	Logical focus sequence
2.4.6 Headings and Labels	AA	Descriptive headings
2.4.7 Focus Visible	AA	Focus indicator visible
2.5.5 Target Size	AAA	44x44px minimum

Understandable

Criterion	Level	Check
3.1.1 Language of Page	A	Lang attribute set
3.2.1 On Focus	A	No unexpected changes
3.3.1 Error Identification	A	Errors clearly described
3.3.2 Labels or Instructions	A	Form guidance provided

Robust

Criterion	Level	Check
4.1.1 Parsing	A	Valid HTML
4.1.2 Name, Role, Value	A	Custom controls accessible

Phase 3: Manual Testing Protocol

Guide through manual checks:

Keyboard Testing

1. Tab through entire page
2. Verify all interactive elements reachable
3. Check focus indicator visibility
4. Test Enter/Space activation
5. Test Escape for modals
6. Verify logical tab order

Screen Reader Testing

1. Enable VoiceOver/NVDA
2. Navigate by landmarks
3. Navigate by headings
4. Tab through interactive elements
5. Test form field announcements
6. Verify dynamic content announced

Visual Testing

1. Zoom to 200%
2. Test Windows High Contrast
3. Check color blindness simulation
4. Verify no information lost

Phase 4: ARIA Validation

Check ARIA usage:

- Roles used correctly
- States updated dynamically
- Properties match element type
- No redundant ARIA
- aria-label/labelledby present where needed
- Live regions for dynamic content

Phase 5: Generate Compliance Report
