Wcag22 A11y Audit

Workflow for Each Test

1. Identify scope (page/component/flow)
2. Collect evidence via search_elements and/or screenshot
3. Apply SC-specific judgment rules
4. Record Pass/Fail with evidence references
5. Provide actionable fix recommendations

Threat Context & Privacy Notes

IMPORTANT: This audit may capture sensitive information.

• Screenshots and accessibility tree dumps may contain: account names, order details, personal data, auth tokens, internal URLs.
• DO NOT include raw sensitive data in the final report.
• If a screenshot contains PII, note this and recommend masking before sharing.
• Contrast/visual judgments are estimates—always recommend verification with dedicated tools (e.g., WebAIM Contrast Checker, axe DevTools).

Pre-Audit Setup (Recommended)

Before starting the audit, confirm with the user:

1. Target Scope: Full page, specific component, or user flow?
2. Target Audience: Who are the primary users? (general public, internal staff, specific disability considerations)
3. Priority SCs: Test all 8 SCs or focus on specific ones?
4. Known Issues: Any existing accessibility issues to verify?

Success Criteria Test Procedures

SC 1.1.1 Non-text Content (Level A)

Goal: All non-text content (images, icons, controls) must have text alternatives.

Test Steps:

1. Find images and icons:

   search_elements(tabId, "image | img")
   search_elements(tabId, "button | link | menuitem | tab | switch")
   

2. Evaluate each element:

   • Check if name attribute exists and is meaningful
   • FAIL conditions:
     • name is empty or missing
     • name is generic: "icon", "image", "button", "img", "graphic", file names (e.g., "logo.png")
     • name duplicates visible text unnecessarily (redundant)
   • PASS conditions:
     • name accurately describes purpose or equivalent information

3. For decorative content:

   • If truly decorative, element should have role="presentation" or role="none", or name="" (explicitly empty)

Common Failures:

• Icon buttons with no accessible name (screen reader announces "button" only)
• Images with alt="image" or alt="logo.png"
• SVG icons without aria-label or visually hidden text

Fix Recommendations:

• Add meaningful alt text to images
• Use aria-label or aria-labelledby for icon buttons
• Use native semantic elements where possible (<button> instead of <div>)

SC 1.4.3 Contrast (Minimum) (Level AA)

Goal: Text must have sufficient contrast against its background.

Requirements:

• Normal text: ≥ 4.5:1 contrast ratio
• Large text (≥24px regular or ≥18.66px bold): ≥ 3:1 contrast ratio

Test Steps:

1. Capture page states:

   capture_screenshot(sendToLLM=true)
   

   • Default state
   • Hover/focus states (use computer to trigger)
   • Error/disabled states if applicable

2. Visual analysis prompt (for LLM):

   "Analyze this screenshot for text contrast issues. Identify any text that appears to have low contrast against its background. Focus on:

   • Small/body text that may be below 4.5:1
   • Placeholder text in input fields
   • Disabled state text
   • Text overlaid on images or gradients List suspicious elements with their approximate location."

3. Record findings:

   • Note: Visual analysis provides estimates only
   • Flag elements for manual verification with contrast checker tools

Common Failures:

• Light gray text on white backgrounds
• Placeholder text with insufficient contrast
• Text on image backgrounds without overlay

Fix Recommendations:

• Increase text color darkness or background lightness
• Add semi-transparent overlay behind text on images
• Use contrast checker tools to verify exact ratios

SC 1.4.11 Non-text Contrast (Level AA)

Goal: UI components and graphical objects must have ≥ 3:1 contrast.

Applies to:

• Input field borders
• Button borders
• Focus indicators
• Icons conveying information
• State indicators (checkboxes, toggles, radio buttons)

Test Steps:

1. Identify UI components:

   search_elements(tabId, "textbox | combobox | checkbox | radio | switch | button | slider")
   

2. Capture states:

   capture_screenshot(sendToLLM=true)
   

   • Document default, hover, focus, active, disabled states

3. Visual analysis prompt:

   "Analyze this screenshot for non-text contrast issues. Check if:

   • Input field borders are clearly visible (≥3:1 against background)
   • Button boundaries are distinguishable
   • Icons are clearly visible
   • Focus indicators have sufficient contrast
   • Checkbox/radio/switch states are visually distinct List any elements that appear to have insufficient contrast."

4. State coverage matrix: Document which states were tested for each component type.

Common Failures:

• Light gray input borders on white backgrounds
• Focus rings with low contrast
• Icon-only buttons where icon color is too light

Fix Recommendations:

• Increase border thickness and/or darkness
• Ensure focus indicators have ≥3:1 contrast
• Test all interactive states, not just default

SC 2.1.1 Keyboard (Level A)

Goal: All functionality must be operable via keyboard.

Test Steps:

1. Identify key tasks: Ask user or determine primary interactive flows

2. Attempt keyboard-only completion:

   computer(action='key', text='Tab')        // Navigate forward
   computer(action='key', text='shift+Tab')  // Navigate backward
   computer(action='key', text='Enter')      // Activate buttons/links
   computer(action='key', text='Space')      // Activate buttons, toggle checkboxes
   computer(action='key', text='Escape')     // Close dialogs/menus
   computer(action='key', text='ArrowDown')  // Navigate within widgets
   

3. At each step:

   • Verify focus is visible (relates to 2.4.7)
   • Verify expected action occurs
   • If blocked, capture screenshot and note the element

4. Cross-reference with accessibility tree:

   search_elements(tabId, "*")
   

   • Check if blocking element has appropriate role
   • Check if element is focusable / disabled

Common Failures:

• Custom components using <div> with onClick but no keyboard handler
• Drag-and-drop only interfaces without keyboard alternative
• Focus not reaching all interactive elements

Fix Recommendations:

• Use native interactive elements (<button>, <a>, <input>)
• Add tabindex="0" and keyboard event handlers to custom components
• Provide keyboard alternatives for mouse-only interactions

SC 2.1.2 No Keyboard Trap (Level A)

Goal: If focus can enter a component, it must be able to exit via keyboard.

Test Steps:

1. Identify potential trap components:

   • Modals/dialogs
   • Dropdown menus
   • Rich text editors
   • Embedded iframes
   • Custom widgets

2. For each component:

   • Tab into the component
   • Attempt to Tab out (forward and backward)
   • Attempt Escape to close (if applicable)
   • Document entry point and exit behavior

3. Capture evidence:

   capture_screenshot(sendToLLM=true)
   

   • Screenshot when entering
   • Screenshot showing focus location
   • Note if any special keys are required and whether instructions are provided

Common Failures:

• Modal dialogs that don't close on Escape
• Focus getting "stuck" in embedded content
• Custom dropdown menus that don't release focus

Fix Recommendations:

• Implement focus trapping in modals with Escape to close
• Ensure all custom widgets have documented exit mechanism
• Provide visible instructions if non-standard keys are required

SC 2.4.3 Focus Order (Level A)

Goal: Focus order must preserve meaning and operability.

Test Steps:

1. Tab through the page:

   computer(action='key', text='Tab')
   

   • Document the sequence of focused elements

2. Compare with visual order:

   capture_screenshot(sendToLLM=true)
   

   • Focus sequence should match left-to-right, top-to-bottom reading order
   • Related elements should be adjacent in focus order

3. Test dynamic content:

   • Open a modal → focus should move to modal
   • Close modal → focus should return to trigger or logical position
   • Expand accordion → new content should be reachable
   • Show error message → focus should move to or near error

4. Check for problematic patterns:

   search_elements(tabId, "tabindex")
   

   • Positive tabindex values (>0) cause unpredictable order

Common Failures:

• Focus jumps to unrelated page sections
• Positive tabindex values creating chaotic order
• Dynamic content inserted but not reachable in logical sequence

Fix Recommendations:

• Use DOM order to control focus order (avoid positive tabindex)
• Manage focus programmatically for dynamic content
• Return focus to logical position after dialog/overlay closes

SC 2.4.7 Focus Visible (Level AA)

Goal: Keyboard focus indicator must be visible.

Test Steps:

1. Ensure keyboard-only mode:

   • Do not use mouse during this test
   • Use Tab to navigate

2. At each focused element:

   capture_screenshot(sendToLLM=true)
   

   • Verify focus indicator is clearly visible
   • Check various element types: buttons, links, inputs, custom controls

3. Visual analysis prompt:

   "Is there a visible focus indicator on the currently focused element in this screenshot? The indicator should be clearly distinguishable (outline, border, background change, underline, or similar). Describe what you see and whether it provides sufficient visual distinction."

4. Cross-reference:

   search_elements(tabId, "*focused*")
   

   • Confirm which element has focused state

Common Failures:

• Global outline: none with no replacement style
• Focus style too subtle (e.g., 1px light gray)
• Focus style matches hover style (can't distinguish keyboard vs mouse)

Fix Recommendations:

• Never remove focus outline without providing alternative
• Ensure focus indicator has ≥3:1 contrast (links to 1.4.11)
• Use :focus-visible for keyboard-only focus styling

SC 4.1.2 Name, Role, Value (Level A)

Goal: All UI components must expose name, role, and value to assistive technology.

Test Steps:

1. Extract interactive elements:

   search_elements(tabId, "button | link | textbox | combobox | checkbox | radio | switch | tab | menuitem | slider | spinbutton | searchbox")
   

2. For each element, verify:

   • Role: Is it correct for the component type?
   • Name: Is there a meaningful accessible name?
   • Value/State: For stateful controls, are states exposed?
     • checked for checkboxes/radios/switches
     • expanded for disclosure widgets
     • selected for tabs/options
     • pressed for toggle buttons
     • value for inputs/sliders

3. Test state changes:

   • Toggle a checkbox → re-run search_elements
   • Expand an accordion → verify expanded state updates
   • Select a tab → verify selected state updates

4. Common patterns to check:

   • Custom checkboxes: must have role="checkbox" and checked state
   • Accordions: trigger must have aria-expanded
   • Tabs: must use role="tab" with aria-selected
   • Menus: proper role="menu" and role="menuitem"

Common Failures:

• <div> buttons without role="button" or accessible name
• Custom toggles without checked state
• Visual "selected" state not reflected in accessibility tree

Fix Recommendations:

• Prefer native HTML elements (they have built-in semantics)
• Use ARIA roles and states correctly for custom components
• Ensure state changes are programmatically announced
