Install targets
Codex install prompt
Install the "accessibility-patterns" agent skill from https://github.com/vibeeval/vibecosystem/tree/main/skills/accessibility-patterns. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: WCAG 2.2 AA compliance, ARIA patterns, keyboard navigation, screen reader optimization After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"vibeeval-accessibility-patterns","task":"Install accessibility-patterns","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes.Supply asset profile

# Accessibility Patterns
## WCAG 2.2 AA Requirements
### Perceivable
| Kriter | Kural | Kontrol | |--------|-------|---------| | 1.1.1 | Non-text content alt text | `<img alt="description">` | | 1.3.1 | Semantic HTML | Headings, landmarks, lists | | 1.4.3 | Color contrast | 4.5:1 normal text, 3:1 large | | 1.4.11 | UI component contrast | 3:1 borders, icons |
### Operable
| Kriter | Kural | Kontrol | |--------|-------|---------| | 2.1.1 | Keyboard accessible | Tab, Enter, Space, Escape | | 2.4.3 | Focus order | Logical tab sequence | | 2.4.7 | Focus visible | Visible focus indicator | | 2.5.8 | Target size | Min 24x24px (44x44px önerilir) |
### Understandable
| Kriter | Kural | Kontrol | |--------|-------|---------| | 3.1.1 | Language of page | `<html lang="tr">` | | 3.2.1 | On focus | No unexpected context change | | 3.3.1 | Error identification | Clear error messages | | 3.3.2 | Labels or instructions | Form labels visible |
## ARIA Patterns
```html <!-- Dialog --> <div role="dialog" aria-modal="true" aria-labelledby="title"> <h2 id="title">Confirm</h2> <button aria-label="Close dialog">×</button> </div>
<!-- Tabs --> <div role="tablist"> <button role="tab" aria-selected="true" aria-controls="panel1">Tab 1</button> <button role="tab" aria-selected="false" aria-controls="panel2">Tab 2</button> </div> <div role="tabpanel" id="panel1">Content 1</div>
<!-- Live region (dynamic updates) --> <div aria-live="polite" aria-atomic="true"> 3 new messages </div> ```
## Keyboard Navigation
```typescript // Focus trap (modal/dialog) function useFocusTrap(ref: RefObject<HTMLElement>) { useEffect(() => { const focusable = ref.current?.querySelectorAll( 'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])' ) const first = focusable?.[0] as HTMLElement const last = focusable?.[focusable.length - 1] as HTMLElement
function handleKeyDown(e: KeyboardEvent) { if (e.key !== 'Tab') return if (e.shiftKey && document.activeElement === first) { e.preventDefault(); last.focus() } else if (!e.shiftKey && document.activeElement === last) { e.preventDefault(); first.focus() } } ref.current?.addEventListener('keydown', handleKeyDown) first?.focus() return () => ref.current?.removeEventListener('keydown', handleKeyDown) }, [ref]) } ```
## Skip Links
```html <a href="#main-content" class="skip-link">Skip to main content</a> <!-- ... navigation ... --> <main id="main-content">...</main>
<style> .skip-link { position: absolute; top: -40px; left: 0; z-index: 100; } .skip-link:focus { top: 0; } </style> ```
## Motion Preferences
```css @media (prefers-reduced-motion: reduce) { *, *::before, *::after { animation-duration: 0.01ms !important; transition-duration: 0.01ms !important; } } ```
## Testing
```bash # axe-core (automated) npx @axe-core/cli https://localhost:3000
# Lighthouse accessibility audit lighthouse --only-categories=accessibility https://localhost:3000 ```
## Checklist
- [ ] Semantic HTML (headings, landmarks, lists) - [ ] Alt text on all images - [ ] Color contrast 4.5:1 (text), 3:1 (UI) - [ ] Keyboard navigable (tab order logical) - [ ] Focus visible indicator - [ ] Skip link to main content - [ ] Form labels and error messages - [ ] ARIA roles where needed - [ ] prefers-reduced-motion respected - [ ] axe-core test pass
## Anti-Patterns
- `<div onclick>` instead of `<button>` - Color-only information (add icon/text) - Auto-playing video/audio - Removing focus outline without replacement - Using ARIA when native HTML suffices
