    "timeout": 10
  }
}

What It Does

• Detects native title tooltips (violation)
• Tests custom tooltips for dismissibility (Escape key)
• Tests hoverability (can hover over tooltip)
• Tests persistence (doesn't disappear too quickly)

Key Output

• native_title_tooltip: Using title attribute (violation)
• not_dismissible: Cannot dismiss with Escape
• not_hoverable: Tooltip disappears when hovering
• not_persistent: Disappears too quickly

Usage

{
  "tool": "web_text_in_images_cremotemcp",
  "arguments": {
    "timeout": 30
  }
}

What It Does

• Uses Tesseract OCR to detect text in images
• Compares detected text with alt text
• Flags missing or insufficient alt text
• Provides specific recommendations

Key Output

• detected_text: Text found in image
• alt_text: Current alt text
• violation_type: missing_alt or insufficient_alt
• recommendations: Specific suggestions

Note: CPU-intensive, allow 30s timeout

---

Tool 5: Cross-Page Consistency

MCP Tool: web_cross_page_consistency_cremotemcp
Command: cremote cross-page-consistency
WCAG: 3.2.3, 3.2.4, 1.3.1

Usage

{
  "tool": "web_cross_page_consistency_cremotemcp",
  "arguments": {
    "urls": [
      "https://example.com/",
      "https://example.com/about",
      "https://example.com/contact"
    ],
    "timeout": 10
  }
}

What It Does

• Navigates to multiple pages
• Identifies common navigation elements
• Checks landmark structure consistency
• Flags missing navigation on some pages

Key Output

• common_navigation: Links present on all pages
• inconsistent_pages: Pages missing common links
• landmark_issues: Inconsistent header/footer/main/nav

---

Tool 6: Animation/Flash Detection

MCP Tool: web_animation_flash_cremotemcp
Command: cremote animation-flash
WCAG: 2.3.1, 2.2.2, 2.3.2

Usage

{
  "tool": "web_animation_flash_cremotemcp",
  "arguments": {
    "timeout": 10
  }
}

What It Does

• Detects CSS animations, GIFs, videos, canvas, SVG
• Estimates flash rate (> 3 flashes/second = violation)
• Checks for pause/stop controls (required if > 5s)
• Detects autoplay violations

Key Output

• flashing_content: Content flashing > 3/second
• no_pause_control: Autoplay > 5s without controls
• rapid_animation: Fast infinite animations
• animation_type: CSS, GIF, video, canvas, SVG

Tool 7: Enhanced Accessibility Tree

MCP Tool: web_enhanced_accessibility_cremotemcp
Command: cremote enhanced-accessibility

Usage

{
  "tool": "web_enhanced_accessibility_cremotemcp",
  "arguments": {
    "timeout": 10
  }
}

What It Does

• Calculates accessible names for interactive elements
• Validates ARIA attributes
• Checks for aria-hidden on interactive elements
• Validates tabindex values (must be 0 or -1)
• Checks landmark labeling (multiple landmarks need labels)

Key Output

• missing_accessible_name: Interactive elements without labels
• aria_hidden_interactive: aria-hidden on buttons/links
• invalid_tabindex: tabindex not 0 or -1
• landmark_issues: Multiple landmarks without labels

Common Usage Patterns

Pattern 1: Quick Audit (All New Tools)

# Run all 7 new tools in sequence
cremote gradient-contrast-check
cremote media-validation
cremote hover-focus-test
cremote text-in-images
cremote animation-flash
cremote enhanced-accessibility
cremote cross-page-consistency --urls "url1,url2,url3"

Pattern 2: Targeted Testing

# Only test specific concerns
cremote gradient-contrast-check --selector .hero
cremote media-validation  # If page has video/audio
cremote text-in-images    # If page has infographics

Pattern 3: Multi-Page Site Audit

# Test each page individually, then cross-page
for page in home about contact services; do
  cremote navigate --url "https://example.com/$page"
  cremote gradient-contrast-check
  cremote enhanced-accessibility
done

# Then check consistency
cremote cross-page-consistency --urls "home,about,contact,services"

Troubleshooting

Tool Takes Too Long

• Gradient Contrast: Reduce selector scope
• Text-in-Images: Increase timeout to 60s, test fewer images
• Cross-Page: Reduce number of URLs, increase timeout

False Positives

• Animation/Flash: Simplified estimation, verify manually
• Hover/Focus: May miss custom implementations

Missing Results

• Media Validation: Ensure video/audio elements exist
• Gradient Contrast: Ensure element has gradient background
• Text-in-Images: Ensure images are loaded and accessible

Dependency Errors

• ImageMagick: sudo apt-get install imagemagick
• Tesseract: sudo apt-get install tesseract-ocr

---

Performance Tips

1. Run in parallel when testing multiple pages
2. Use specific selectors to reduce processing time
3. Increase timeouts for complex pages
4. Test incrementally during development
5. Cache results to avoid re-running expensive tests
