```json
{
  "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

## Common Usage Patterns

### Pattern 1: Quick Audit (All New Tools)
```bash
# 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
```bash
# 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
```bash
# 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

## Integration with Existing Tools

### Combine with Axe-Core
```bash
cremote inject-axe
cremote run-axe --run-only wcag2aa
cremote gradient-contrast-check  # Enhanced contrast testing
cremote enhanced-accessibility    # Enhanced ARIA validation
```

### Combine with Keyboard Testing
```bash
cremote keyboard-test
cremote enhanced-accessibility  # Validates accessible names
cremote hover-focus-test        # Tests hover/focus content
```

### Combine with Responsive Testing
```bash
cremote zoom-test
cremote reflow-test
cremote gradient-contrast-check  # Verify contrast at all sizes
```
