# Send Accessibility Engine to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

Key trend: ADA lawsuits in the US hit 4,600+ in 2023. EU EAA enforcement starts June 2025. This is NOT optional.

### Principle 1: PERCEIVABLE (users must be able to perceive content)

1.1 Text Alternatives

1.1.1 Non-text Content (A) — Every <img>, <svg>, icon has appropriate alt text

Informative images: descriptive alt (alt="Bar chart showing Q3 revenue of $2.4M")
Decorative images: empty alt (alt="") or CSS background
Functional images (buttons/links): describe the action (alt="Search")
Complex images (charts/diagrams): short alt + long description
Image of text: use real text instead (exception: logos)
Form image buttons: alt describes the action
Test: Turn off images — can you still understand the page?

1.2 Time-Based Media

1.2.1 Audio-only/Video-only (A) — Provide transcript (audio) or text description (video)
 1.2.2 Captions (A) — All prerecorded video has synchronized captions
 1.2.3 Audio Description (A) — Prerecorded video has audio description or full text alternative
 1.2.4 Live Captions (AA) — Live video has real-time captions
 1.2.5 Audio Description (AA) — Prerecorded video has audio description track

Caption quality checklist: Speaker identified, [sound effects], [music], 99%+ accuracy, sync within 1 second

1.3 Adaptable

1.3.1 Info and Relationships (A) — Structure conveyed visually is also in markup

Headings use <h1>-<h6> (not just bold text)
Lists use <ul>, <ol>, <dl> (not styled divs)
Tables use <th>, scope, <caption>
Forms use <label> + for attribute (not placeholder-only)
Regions use landmarks (<nav>, <main>, <aside>, <footer>)


 1.3.2 Meaningful Sequence (A) — DOM order matches visual reading order
 1.3.3 Sensory Characteristics (A) — Instructions don't rely solely on shape, color, size, location, sound

❌ "Click the green button"
✅ "Click the Submit button (green, bottom right)"


 1.3.4 Orientation (AA) — Content not restricted to portrait or landscape
 1.3.5 Identify Input Purpose (AA) — Form fields have autocomplete attributes

1.4 Distinguishable

1.4.1 Use of Color (A) — Color is NOT the only way to convey information

Links: underlined OR other non-color indicator
Form errors: icon + text, not just red border
Charts: patterns/labels, not just color coding


 1.4.2 Audio Control (A) — Auto-playing audio can be paused/stopped within 3 seconds
 1.4.3 Contrast (Minimum) (AA) — Text contrast ratio ≥ 4.5:1 (normal) / 3:1 (large text ≥18pt or 14pt bold)
 1.4.4 Resize Text (AA) — Text resizable to 200% without loss of content/function
 1.4.5 Images of Text (AA) — Don't use images of text (exception: logos)
 1.4.10 Reflow (AA) — No horizontal scrolling at 320px viewport width (1280px at 400% zoom)
 1.4.11 Non-text Contrast (AA) — UI components and graphical objects ≥ 3:1 contrast
 1.4.12 Text Spacing (AA) — No content loss when overriding: line-height 1.5×, paragraph spacing 2×, letter spacing 0.12em, word spacing 0.16em
 1.4.13 Content on Hover/Focus (AA) — Tooltips/popovers: dismissible (Esc), hoverable, persistent until dismissed

### Principle 2: OPERABLE (users must be able to operate the interface)

2.1 Keyboard Accessible

2.1.1 Keyboard (A) — ALL functionality available via keyboard

Tab through all interactive elements
Enter/Space activates buttons and links
Arrow keys navigate within components (tabs, menus, sliders)
No keyboard traps (can always Tab/Esc out)


 2.1.2 No Keyboard Trap (A) — Focus never gets stuck
 2.1.4 Character Key Shortcuts (A) — Single-character shortcuts can be turned off or remapped

2.2 Enough Time

2.2.1 Timing Adjustable (A) — Session timeouts: warn 20+ seconds before, allow extension
 2.2.2 Pause, Stop, Hide (A) — Moving/auto-updating content can be paused (carousels, tickers, animations)

2.3 Seizures and Physical Reactions

2.3.1 Three Flashes (A) — Nothing flashes more than 3 times per second

2.4 Navigable

2.4.1 Bypass Blocks (A) — "Skip to main content" link (first focusable element)
 2.4.2 Page Titled (A) — Every page has descriptive <title> (Pattern: Page Name | Site Name)
 2.4.3 Focus Order (A) — Tab order follows logical reading sequence
 2.4.4 Link Purpose (A) — Link text describes destination (no "click here", "read more")
 2.4.5 Multiple Ways (AA) — 2+ ways to find pages (nav + search, or nav + sitemap)
 2.4.6 Headings and Labels (AA) — Headings and labels are descriptive
 2.4.7 Focus Visible (AA) — Keyboard focus indicator is clearly visible

Minimum: 2px solid outline, 3:1 contrast against background
Never: outline: none without a visible replacement

2.5 Input Modalities

2.5.1 Pointer Gestures (A) — Multi-point gestures (pinch, swipe) have single-pointer alternatives
 2.5.2 Pointer Cancellation (A) — Actions fire on up-event (not down), can be aborted
 2.5.3 Label in Name (A) — Visible label text is included in accessible name
 2.5.4 Motion Actuation (A) — Shake/tilt features have button alternatives

### Principle 3: UNDERSTANDABLE (content and interface must be understandable)

3.1 Readable

3.1.1 Language of Page (A) — <html lang="en"> (or appropriate language code)
 3.1.2 Language of Parts (AA) — Foreign language passages marked with lang attribute

3.2 Predictable

3.2.1 On Focus (A) — No unexpected context change on focus
 3.2.2 On Input (A) — No unexpected context change on input (unless warned)
 3.2.3 Consistent Navigation (AA) — Navigation order consistent across pages
 3.2.4 Consistent Identification (AA) — Same function = same label everywhere

3.3 Input Assistance

3.3.1 Error Identification (A) — Errors described in text (not just color)
 3.3.2 Labels or Instructions (A) — Required fields, format hints provided upfront
 3.3.3 Error Suggestion (AA) — Suggest corrections when possible
 3.3.4 Error Prevention (AA) — Legal/financial submissions: reversible, or confirmed, or reviewed

### Principle 4: ROBUST (content must be compatible with assistive tech)

4.1.1 Parsing (A) — Valid HTML (no duplicate IDs, proper nesting)
 4.1.2 Name, Role, Value (A) — Custom components expose correct ARIA roles/states
 4.1.3 Status Messages (AA) — Status messages announced without focus change (role="alert", aria-live)

### Landmark Roles (use HTML5 elements, not role attributes when possible)

<header>     → banner (page header)
<nav>        → navigation
<main>       → main content (one per page)
<aside>      → complementary
<footer>     → contentinfo (page footer)
<section>    → region (with aria-label)
<form>       → form (with aria-label)
<search>     → search

### Common ARIA Patterns

PatternKey ARIAKeyboardModal dialogrole="dialog", aria-modal="true", aria-labelledbyEsc closes, Tab trapped inside, focus returns on closeTabsrole="tablist/tab/tabpanel", aria-selected, aria-controlsArrow keys switch tabs, Tab enters panelAccordion<button aria-expanded>, aria-controlsEnter/Space toggles, all keyboard reachableMenurole="menu/menuitem", aria-haspopupArrow keys navigate, Esc closes, Enter selectsCombobox/autocompleterole="combobox", aria-expanded, aria-activedescendantArrow keys navigate list, Enter selects, Esc closesAlert/toastrole="alert" or aria-live="assertive"Auto-announced, dismissibleProgressrole="progressbar", aria-valuenow/min/maxAnnounced on changeToggle buttonaria-pressed="true/false"Space/Enter togglesTooltiprole="tooltip", aria-describedbyAppears on focus+hover, Esc dismisses

### ARIA Rules of Engagement

First rule of ARIA: Don't use ARIA if native HTML works — <button> > <div role="button">
Second rule: Don't change native semantics — Don't <h2 role="tab">
Third rule: All interactive ARIA controls must be keyboard accessible
Fourth rule: Don't use role="presentation" or aria-hidden="true" on focusable elements
Fifth rule: All interactive elements must have an accessible name

### Accessible Name Priority (browser resolution order)

aria-labelledby (references another element's text)
aria-label (string label)
<label> association (for form controls)
Contents (button text, link text)
title attribute (last resort — avoid)
placeholder (NOT a label — supplementary only)

### 4-Layer Testing Pyramid

Layer 1: Automated Scanning (catches ~30% of issues)

Run on EVERY build/PR:

Tools (all free):

axe-core — industry standard, lowest false positives
# In Playwright/Cypress
npm install @axe-core/playwright  # or @axe-core/cypress
# In CI
npm install @axe-core/cli
axe https://your-site.com --tags wcag2a,wcag2aa


Lighthouse — Chrome DevTools → Lighthouse → Accessibility
WAVE — wave.webaim.org (visual overlay)
Pa11y — CLI scanner for CI pipelines
pa11y https://your-site.com --standard WCAG2AA

CI pipeline integration:

# GitHub Actions example
a11y-test:
  runs-on: ubuntu-latest
  steps:
    - uses: actions/checkout@v4
    - run: npm ci && npm run build
    - run: npx pa11y-ci --config .pa11yci.json
    - run: npx playwright test --grep @a11y

Layer 2: Keyboard Testing (catches navigation issues)

Test EVERY page/feature manually:

Tab test: Tab through entire page — can you reach everything? Is order logical?
Focus visibility test: Is the focus indicator always visible and clear?
Activation test: Can you activate every button, link, form control with Enter/Space?
Trap test: Can you always Tab or Esc out of components (modals, menus)?
Skip link test: Does "Skip to main content" work?

Keyboard testing checklist per page:

keyboard_test:
  page: ""
  date: ""
  tester: ""
  results:
    all_interactive_reachable: true/false
    logical_tab_order: true/false
    focus_always_visible: true/false
    no_keyboard_traps: true/false
    skip_link_works: true/false
    custom_components_keyboard_operable: true/false
  issues: []

Layer 3: Screen Reader Testing (catches semantic issues)

Test key flows with at least ONE screen reader:

Screen ReaderOSBrowserCostNVDAWindowsFirefox/ChromeFreeVoiceOvermacOS/iOSSafariBuilt-inJAWSWindowsChrome/Edge$$$TalkBackAndroidChromeBuilt-in

Essential screen reader checks:

Page structure announced (headings, landmarks, lists)
Images described (or correctly hidden if decorative)
Forms: labels read, errors announced, required fields indicated
Dynamic content announced (alerts, loading states, live regions)
Custom components: role, name, state all announced

Quick VoiceOver test (macOS):

Cmd+F5 to toggle
VO+Right arrow to navigate
VO+U for rotor (headings, links, landmarks)
Tab for interactive elements only

Layer 4: Manual Expert Review (catches context & usability issues)

Quarterly or before major releases:

Content readability and plain language
Cognitive load assessment
Error recovery paths
Motion/animation sensitivity
Touch target sizing (mobile)
Color independence verification

### Fix 1: Missing alt text

<!-- ❌ -->
<img src="chart.png">
<img src="decorative-swoosh.svg">

<!-- ✅ -->
<img src="chart.png" alt="Revenue grew 34% from $1.8M to $2.4M in Q3 2025">
<img src="decorative-swoosh.svg" alt="" role="presentation">

### Fix 2: Color-only indicators

<!-- ❌ Error shown only by red border -->
<input style="border-color: red">

<!-- ✅ Error with icon, text, and color -->
<input aria-invalid="true" aria-describedby="email-error" style="border-color: red">
<span id="email-error" role="alert">⚠️ Please enter a valid email address</span>

### Fix 3: Custom button

<!-- ❌ Div pretending to be a button -->
<div class="btn" onclick="submit()">Submit</div>

<!-- ✅ Just use a button -->
<button type="submit">Submit</button>

<!-- ✅ If you MUST use a div (you shouldn't) -->
<div role="button" tabindex="0" onclick="submit()" onkeydown="if(e.key==='Enter'||e.key===' ')submit()">Submit</div>

### Fix 4: Form labels

<!-- ❌ Placeholder-only label -->
<input placeholder="Email address">

<!-- ✅ Visible label -->
<label for="email">Email address</label>
<input id="email" type="email" autocomplete="email" placeholder="you@example.com">

<!-- ✅ Visually hidden label (when design requires it) -->
<label for="search" class="sr-only">Search</label>
<input id="search" type="search" placeholder="Search...">

### Fix 5: Focus management (SPA route changes)

// After client-side navigation:
// 1. Update document.title
document.title = \`${newPageName} | Site Name\`;

// 2. Move focus to main content or h1
const main = document.querySelector('main h1') || document.querySelector('main');
main.setAttribute('tabindex', '-1');
main.focus();

// 3. Announce to screen readers
const announcer = document.getElementById('route-announcer');
announcer.textContent = \`Navigated to ${newPageName}\`;
// <div id="route-announcer" aria-live="assertive" class="sr-only"></div>

### Fix 6: Modal focus trap

function trapFocus(modal) {
  const focusable = modal.querySelectorAll(
    'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
  );
  const first = focusable[0];
  const last = focusable[focusable.length - 1];

  modal.addEventListener('keydown', (e) => {
    if (e.key === 'Escape') { closeModal(); return; }
    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();
    }
  });

  first.focus(); // Move focus into modal on open
}
// On close: return focus to the trigger element

### Fix 7: Live region for dynamic content

<!-- Status messages (polite — waits for pause) -->
<div aria-live="polite" aria-atomic="true" id="status">
  <!-- JS updates: "3 results found", "Item added to cart" -->
</div>

<!-- Error/urgent messages (assertive — interrupts) -->
<div role="alert" id="error-banner">
  <!-- JS updates: "Payment failed. Please try again." -->
</div>

### CSS: Visually Hidden (screen reader only)

.sr-only {
  position: absolute;
  width: 1px;
  height: 1px;
  padding: 0;
  margin: -1px;
  overflow: hidden;
  clip: rect(0, 0, 0, 0);
  white-space: nowrap;
  border-width: 0;
}

### Color Contrast Requirements

Tools for checking:

Colour Contrast Analyser (desktop app)
WebAIM Contrast Checker (webaim.org/resources/contrastchecker)
Stark (Figma plugin)

Minimum ratios:

ElementWCAG AAWCAG AAANormal text (<18pt)4.5:17:1Large text (≥18pt or ≥14pt bold)3:14.5:1UI components & graphics3:1—Focus indicator3:1—Disabled elementsExempt—

### Touch Target Sizing

StandardMinimum SizeSpacingWCAG 2.5.8 (AAA)44×44 CSS px—WCAG 2.5.5 (AA)24×24 CSS px24px from other targetsApple HIG44×44 pt—Material Design48×48 dp8dp spacingRecommendation44×44 px minimum8px spacing

### Typography Accessibility

Base font size: 16px minimum (body text)
Line height: 1.5× minimum for body text
Line length: 50-75 characters (measure)
Paragraph spacing: 1.5× font size minimum
Font choice: sans-serif for UI, high x-height, clear letterforms
Never: All caps for long text, justified alignment, font size < 12px

### Animation & Motion

/* Respect user preference */
@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
    scroll-behavior: auto !important;
  }
}

All animations: provide pause/stop control
No content conveyed only through animation
Parallax scrolling: provide alternative or respect prefers-reduced-motion
Auto-playing video: never. User-initiated only.

### Dark Mode Accessibility

Re-check ALL contrast ratios in dark mode (common failure point)
Don't just invert — pure white (#fff) on dark backgrounds causes halation
Use off-white (#e0e0e0 to #f0f0f0) on dark backgrounds
Colored text: re-verify contrast on dark backgrounds
Images: consider transparent PNGs on dark backgrounds

### Phase 7: Component Accessibility Specifications

For each common component, specify the complete accessible behavior:

### Button

semantics: "<button> or role='button'"
accessible_name: "visible text or aria-label"
keyboard:
  - "Enter/Space: activate"
states:
  - "aria-disabled='true' (not HTML disabled — that removes from tab order)"
  - "aria-pressed for toggles"
  - "aria-expanded for menus/dropdowns"
notes:
  - "Never use <a> for actions (buttons do things, links go places)"
  - "Loading state: aria-busy='true', disable click, announce 'Loading...'"

### Form Field

required:
  - "Visible <label> with for= attribute"
  - "Error message with aria-describedby"
  - "Required indicator: aria-required='true' + visible '(required)' or '*' with legend"
  - "autocomplete attribute for user data fields"
keyboard:
  - "Tab to reach, type to fill"
  - "Error: focus moves to first error field on submit"
validation:
  - "Inline validation: after blur, not on every keystroke"
  - "Error format: What went wrong + how to fix it"
  - "Success: subtle confirmation, no modal"
group:
  - "Related fields: <fieldset> + <legend> (radio groups, address blocks)"

### Data Table

required:
  - "<table>, <thead>, <tbody>, <th scope='col/row'>"
  - "<caption> describing the table"
  - "Complex tables: headers= attribute on <td>"
keyboard:
  - "Sortable: button in <th>, aria-sort='ascending/descending/none'"
  - "Pagination: standard button/link navigation"
responsive:
  - "Small screens: horizontal scroll with sticky first column, or card layout"
  - "Never hide columns without providing access to that data"
avoid:
  - "Layout tables (use CSS grid/flex)"
  - "Nested tables"

### Navigation

required:
  - "<nav aria-label='Main'> (label if multiple navs)"
  - "Current page: aria-current='page'"
  - "Skip link as first focusable element"
keyboard:
  - "Tab to enter, Tab through items"
  - "Dropdown menus: Enter/Space to open, Arrow keys to navigate, Esc to close"
mobile:
  - "Hamburger: <button aria-expanded='false' aria-controls='menu-id'>"
  - "Update aria-expanded on toggle"

### Phase 8: Accessibility Scoring Rubric (0-100)

Scoring thresholds:

90-100: Audit-ready. Maintain with automated testing.
70-89: Good foundation. Fix remaining issues within 30 days.
50-69: Significant gaps. Prioritize critical/serious issues.
Below 50: Major remediation needed. Start with Phase 9 priority matrix.
