# AUTOMATED TESTING ENHANCEMENTS FOR CREMOTE ADA SUITE
**Date:** October 2, 2025
**Purpose:** Propose creative solutions to automate currently manual accessibility tests
**Philosophy:** KISS - Keep it Simple, Stupid. Practical solutions using existing tools.
---
## EXECUTIVE SUMMARY
Currently, our cremote MCP suite automates ~70% of WCAG 2.1 AA testing. This document proposes practical solutions to increase automation coverage to **~85-90%** by leveraging:
1. **ImageMagick** for gradient contrast analysis
2. **Screenshot-based analysis** for visual testing
3. **OCR tools** for text-in-images detection
4. **Video frame analysis** for animation/flash testing
5. **Enhanced JavaScript injection** for deeper DOM analysis
---
## CATEGORY 1: GRADIENT & COMPLEX BACKGROUND CONTRAST
### Current Limitation
**Problem:** Axe-core reports "incomplete" for text on gradient backgrounds because it cannot calculate contrast ratios for non-solid colors.
**Example from our assessment:**
- Navigation menu links (background color could not be determined due to overlap)
- Gradient backgrounds on hero section (contrast cannot be automatically calculated)
### Proposed Solution: ImageMagick Gradient Analysis
**Approach:**
1. Take screenshot of specific element using `web_screenshot_element_cremotemcp_cremotemcp`
2. Use ImageMagick to analyze color distribution
3. Calculate contrast ratio against darkest/lightest points in gradient
4. Report worst-case contrast ratio
**Implementation:**
```bash
# Step 1: Take element screenshot
web_screenshot_element_cremotemcp(selector=".hero-section", output="/tmp/hero.png")
# Step 2: Extract text color from computed styles
text_color=$(console_command "getComputedStyle(document.querySelector('.hero-section h1')).color")
# Step 3: Find darkest and lightest colors in background
convert /tmp/hero.png -format "%[fx:minima]" info: > darkest.txt
convert /tmp/hero.png -format "%[fx:maxima]" info: > lightest.txt
# Step 4: Calculate contrast ratios
# Compare text color against both extremes
# Report the worst-case scenario
# Step 5: Sample multiple points across gradient
convert /tmp/hero.png -resize 10x10! -depth 8 txt:- | grep -v "#" | awk '{print $3}'
# This gives us 100 sample points across the gradient
```
**Tools Required:**
- ImageMagick (already available in most containers)
- Basic shell scripting
- Color contrast calculation library (can use existing cremote contrast checker)
**Accuracy:** ~95% - Will catch most gradient contrast issues
**Implementation Effort:** 8-16 hours
---
## CATEGORY 2: TEXT IN IMAGES DETECTION
### Current Limitation
**Problem:** WCAG 1.4.5 requires text to be actual text, not images of text (except logos). Currently requires manual visual inspection.
### Proposed Solution: OCR-Based Text Detection
**Approach:**
1. Screenshot all images on page
2. Run OCR (Tesseract) on each image
3. If text detected, flag for manual review
4. Cross-reference with alt text to verify equivalence
**Implementation:**
```bash
# Step 1: Extract all image URLs
images=$(console_command "Array.from(document.querySelectorAll('img')).map(img => ({src: img.src, alt: img.alt}))")
# Step 2: Download each image
for img in $images; do
curl -o /tmp/img_$i.png $img
# Step 3: Run OCR
tesseract /tmp/img_$i.png /tmp/img_$i_text
# Step 4: Check if significant text detected
word_count=$(wc -w < /tmp/img_$i_text.txt)
if [ $word_count -gt 5 ]; then
echo "WARNING: Image contains text: $img"
echo "Detected text: $(cat /tmp/img_$i_text.txt)"
echo "Alt text: $alt"
echo "MANUAL REVIEW REQUIRED: Verify if this should be HTML text instead"
fi
done
```
**Tools Required:**
- Tesseract OCR (open source, widely available)
- curl or wget for image download
- Basic shell scripting
**Accuracy:** ~80% - Will catch obvious text-in-images, may miss stylized text
**False Positives:** Logos, decorative text (acceptable - requires manual review anyway)
**Implementation Effort:** 8-12 hours
---
## CATEGORY 3: ANIMATION & FLASH DETECTION
### Current Limitation
**Problem:** WCAG 2.3.1 requires no content flashing more than 3 times per second. Currently requires manual observation.
### Proposed Solution: Video Frame Analysis
**Approach:**
1. Record video of page for 10 seconds using Chrome DevTools Protocol
2. Extract frames using ffmpeg
3. Compare consecutive frames for brightness changes
4. Count flashes per second
5. Flag if >3 flashes/second detected
**Implementation:**
```bash
# Step 1: Start video recording via CDP
# (Chrome DevTools Protocol supports screencast)
console_command "
chrome.send('Page.startScreencast', {
format: 'png',
quality: 80,
maxWidth: 1280,
maxHeight: 800
});
"
# Step 2: Record for 10 seconds, save frames
# Step 3: Analyze frames with ffmpeg
ffmpeg -i /tmp/recording.mp4 -vf "select='gt(scene,0.3)',showinfo" -f null - 2>&1 | \
grep "Parsed_showinfo" | wc -l
# Step 4: Calculate flashes per second
# If scene changes > 30 in 10 seconds = 3+ per second = FAIL
# Step 5: For brightness-based flashing
ffmpeg -i /tmp/recording.mp4 -vf "signalstats" -f null - 2>&1 | \
grep "lavfi.signalstats.YAVG" | \
awk '{print $NF}' > brightness.txt
# Analyze brightness.txt for rapid changes
```
**Tools Required:**
- ffmpeg (video processing)
- Chrome DevTools Protocol screencast API
- Python/shell script for analysis
**Accuracy:** ~90% - Will catch most flashing content
**Implementation Effort:** 16-24 hours (more complex)
---
## CATEGORY 4: HOVER/FOCUS CONTENT PERSISTENCE
### Current Limitation
**Problem:** WCAG 1.4.13 requires hover/focus-triggered content to be dismissible, hoverable, and persistent. Currently requires manual testing.
### Proposed Solution: Automated Interaction Testing
**Approach:**
1. Identify all elements with hover/focus event listeners
2. Programmatically trigger hover/focus
3. Measure how long content stays visible
4. Test if Esc key dismisses content
5. Test if mouse can move to triggered content
**Implementation:**
```javascript
// Step 1: Find all elements with hover/focus handlers
const elementsWithHover = Array.from(document.querySelectorAll('*')).filter(el => {
const style = getComputedStyle(el, ':hover');
return style.display !== getComputedStyle(el).display ||
style.visibility !== getComputedStyle(el).visibility;
});
// Step 2: Test each element
for (const el of elementsWithHover) {
// Trigger hover
el.dispatchEvent(new MouseEvent('mouseover', {bubbles: true}));
// Wait 100ms
await new Promise(r => setTimeout(r, 100));
// Check if new content appeared
const newContent = document.querySelector('[role="tooltip"], .tooltip, .popover');
if (newContent) {
// Test 1: Can we hover over the new content?
const rect = newContent.getBoundingClientRect();
const canHover = rect.width > 0 && rect.height > 0;
// Test 2: Does Esc dismiss it?
document.dispatchEvent(new KeyboardEvent('keydown', {key: 'Escape'}));
await new Promise(r => setTimeout(r, 100));
const dismissed = !document.contains(newContent);
// Test 3: Does it persist when we move mouse away briefly?
el.dispatchEvent(new MouseEvent('mouseout', {bubbles: true}));
await new Promise(r => setTimeout(r, 500));
const persistent = document.contains(newContent);
console.log({
element: el,
canHover,
dismissible: dismissed,
persistent
});
}
}
```
**Tools Required:**
- JavaScript injection via cremote
- Chrome DevTools Protocol for event simulation
- Timing and state tracking
**Accuracy:** ~85% - Will catch most hover/focus issues
**Implementation Effort:** 12-16 hours
---
## CATEGORY 5: SEMANTIC MEANING & COGNITIVE LOAD
### Current Limitation
**Problem:** Some WCAG criteria require human judgment (e.g., "headings describe topic or purpose", "instructions don't rely solely on sensory characteristics").
### Proposed Solution: LLM-Assisted Analysis
**Approach:**
1. Extract all headings, labels, and instructions
2. Use LLM (Claude, GPT-4) to analyze semantic meaning
3. Check for sensory-only instructions (e.g., "click the red button")
4. Verify heading descriptiveness
5. Flag potential issues for manual review
**Implementation:**
```javascript
// Step 1: Extract content for analysis
const analysisData = {
headings: Array.from(document.querySelectorAll('h1,h2,h3,h4,h5,h6')).map(h => ({
level: h.tagName,
text: h.textContent.trim(),
context: h.parentElement.textContent.substring(0, 200)
})),
instructions: Array.from(document.querySelectorAll('label, .instructions, [role="note"]')).map(el => ({
text: el.textContent.trim(),
context: el.parentElement.textContent.substring(0, 200)
})),
links: Array.from(document.querySelectorAll('a')).map(a => ({
text: a.textContent.trim(),
href: a.href,
context: a.parentElement.textContent.substring(0, 100)
}))
};
// Step 2: Send to LLM for analysis
const prompt = `
Analyze this web content for accessibility issues:
1. Do any instructions rely solely on sensory characteristics (color, shape, position, sound)?
Examples: "click the red button", "the square icon", "button on the right"
2. Are headings descriptive of their section content?
Flag generic headings like "More Information", "Click Here", "Welcome"
3. Are link texts descriptive of their destination?
Flag generic links like "click here", "read more", "learn more"
Content to analyze:
${JSON.stringify(analysisData, null, 2)}
Return JSON with:
{
"sensory_instructions": [{element, issue, suggestion}],
"generic_headings": [{heading, issue, suggestion}],
"unclear_links": [{link, issue, suggestion}]
}
`;
// Step 3: Parse LLM response and generate report
```
**Tools Required:**
- LLM API access (Claude, GPT-4, or local model)
- JSON parsing
- Integration with cremote reporting
**Accuracy:** ~75% - LLM can catch obvious issues, but still requires human review
**Implementation Effort:** 16-24 hours
---
## CATEGORY 6: TIME-BASED MEDIA (VIDEO/AUDIO)
### Current Limitation
**Problem:** WCAG 1.2.x criteria require captions, audio descriptions, and transcripts. Currently requires manual review of media content.
### Proposed Solution: Automated Media Inventory & Validation
**Approach:**
1. Detect all video/audio elements
2. Check for caption tracks
3. Verify caption files are accessible
4. Use speech-to-text to verify caption accuracy (optional)
5. Check for audio description tracks
**Implementation:**
```javascript
// Step 1: Find all media elements
const mediaElements = {
videos: Array.from(document.querySelectorAll('video')).map(v => ({
src: v.src,
tracks: Array.from(v.querySelectorAll('track')).map(t => ({
kind: t.kind,
src: t.src,
srclang: t.srclang,
label: t.label
})),
controls: v.hasAttribute('controls'),
autoplay: v.hasAttribute('autoplay'),
duration: v.duration
})),
audios: Array.from(document.querySelectorAll('audio')).map(a => ({
src: a.src,
controls: a.hasAttribute('controls'),
autoplay: a.hasAttribute('autoplay'),
duration: a.duration
}))
};
// Step 2: Validate each video
for (const video of mediaElements.videos) {
const issues = [];
// Check for captions
const captionTrack = video.tracks.find(t => t.kind === 'captions' || t.kind === 'subtitles');
if (!captionTrack) {
issues.push('FAIL: No caption track found (WCAG 1.2.2)');
} else {
// Verify caption file is accessible
const response = await fetch(captionTrack.src);
if (!response.ok) {
issues.push(`FAIL: Caption file not accessible: ${captionTrack.src}`);
}
}
// Check for audio description
const descriptionTrack = video.tracks.find(t => t.kind === 'descriptions');
if (!descriptionTrack) {
issues.push('WARNING: No audio description track found (WCAG 1.2.5)');
}
// Check for transcript link
const transcriptLink = document.querySelector(`a[href*="transcript"]`);
if (!transcriptLink) {
issues.push('WARNING: No transcript link found (WCAG 1.2.3)');
}
console.log({video: video.src, issues});
}
```
**Enhanced with Speech-to-Text (Optional):**
```bash
# Download video
youtube-dl -o /tmp/video.mp4 $video_url
# Extract audio
ffmpeg -i /tmp/video.mp4 -vn -acodec pcm_s16le -ar 16000 /tmp/audio.wav
# Run speech-to-text (using Whisper or similar)
whisper /tmp/audio.wav --model base --output_format txt
# Compare with caption file
diff /tmp/audio.txt /tmp/captions.vtt
# Calculate accuracy percentage
```
**Tools Required:**
- JavaScript for media detection
- fetch API for caption file validation
- Optional: Whisper (OpenAI) or similar for speech-to-text
- ffmpeg for audio extraction
**Accuracy:**
- Media detection: ~100%
- Caption presence: ~100%
- Caption accuracy (with STT): ~70-80%
**Implementation Effort:**
- Basic validation: 8-12 hours
- With speech-to-text: 24-32 hours
---
## CATEGORY 7: MULTI-PAGE CONSISTENCY
### Current Limitation
**Problem:** WCAG 3.2.3 (Consistent Navigation) and 3.2.4 (Consistent Identification) require checking consistency across multiple pages. Currently requires manual comparison.
### Proposed Solution: Automated Cross-Page Analysis
**Approach:**
1. Crawl all pages on site
2. Extract navigation structure from each page
3. Compare navigation order across pages
4. Extract common elements (search, login, cart, etc.)
5. Verify consistent labeling and identification
**Implementation:**
```javascript
// Step 1: Crawl site and extract navigation
const siteMap = [];
async function crawlPage(url, visited = new Set()) {
if (visited.has(url)) return;
visited.add(url);
await navigateTo(url);
const pageData = {
url,
navigation: Array.from(document.querySelectorAll('nav a, header a')).map(a => ({
text: a.textContent.trim(),
href: a.href,
order: Array.from(a.parentElement.children).indexOf(a)
})),
commonElements: {
search: document.querySelector('[type="search"], [role="search"]')?.outerHTML,
login: document.querySelector('a[href*="login"], button:contains("Login")')?.outerHTML,
cart: document.querySelector('a[href*="cart"], .cart')?.outerHTML
}
};
siteMap.push(pageData);
// Find more pages to crawl
const links = Array.from(document.querySelectorAll('a[href]'))
.map(a => a.href)
.filter(href => href.startsWith(window.location.origin));
for (const link of links.slice(0, 50)) { // Limit crawl depth
await crawlPage(link, visited);
}
}
// Step 2: Analyze consistency
function analyzeConsistency(siteMap) {
const issues = [];
// Check navigation order consistency
const navOrders = siteMap.map(page =>
page.navigation.map(n => n.text).join('|')
);
const uniqueOrders = [...new Set(navOrders)];
if (uniqueOrders.length > 1) {
issues.push({
criterion: 'WCAG 3.2.3 Consistent Navigation',
severity: 'FAIL',
description: 'Navigation order varies across pages',
pages: siteMap.filter((p, i) => navOrders[i] !== navOrders[0]).map(p => p.url)
});
}
// Check common element consistency
const searchElements = siteMap.map(p => p.commonElements.search).filter(Boolean);
if (new Set(searchElements).size > 1) {
issues.push({
criterion: 'WCAG 3.2.4 Consistent Identification',
severity: 'FAIL',
description: 'Search functionality identified inconsistently across pages'
});
}
return issues;
}
```
**Tools Required:**
- Web crawler (can use existing cremote navigation)
- DOM extraction and comparison
- Pattern matching algorithms
**Accuracy:** ~90% - Will catch most consistency issues
**Implementation Effort:** 16-24 hours

# CREMOTE ADA AUTOMATION ENHANCEMENT PLAN
**Date:** October 2, 2025
**Status:** APPROVED FOR IMPLEMENTATION
**Goal:** Increase automated testing coverage from 70% to 85%
**Timeline:** 6-8 weeks
**Philosophy:** KISS - Keep it Simple, Stupid
---
## EXECUTIVE SUMMARY
This plan outlines practical enhancements to the cremote MCP accessibility testing suite. We will implement 6 new automated testing capabilities using proven, simple tools. The caption accuracy validation using speech-to-text is **EXCLUDED** as it's beyond our current platform capabilities.
**Target Coverage Increase:** 70% → 85% (15 percentage point improvement)
---
## SCOPE EXCLUSIONS
### ❌ NOT INCLUDED IN THIS PLAN:
1. **Speech-to-Text Caption Accuracy Validation**
- Reason: Requires external services (Whisper API, Google Speech-to-Text)
- Complexity: High (video processing, audio extraction, STT integration)
- Cost: Ongoing API costs or significant compute resources
- Alternative: Manual review or future enhancement
2. **Real-time Live Caption Testing**
- Reason: Requires live streaming infrastructure
- Complexity: Very high (real-time monitoring, streaming protocols)
- Alternative: Manual testing during live events
3. **Complex Video Content Analysis**
- Reason: Determining if visual content requires audio description needs human judgment
- Alternative: Flag all videos without descriptions for manual review
---
## IMPLEMENTATION PHASES
### **PHASE 1: FOUNDATION (Weeks 1-2)**
**Goal:** Implement high-impact, low-effort enhancements
**Effort:** 28-36 hours
#### 1.1 Gradient Contrast Analysis (ImageMagick)
**Priority:** CRITICAL
**Effort:** 8-12 hours
**Solves:** "Incomplete" findings for text on gradient backgrounds
**Deliverables:**
- New MCP tool: `web_gradient_contrast_check_cremotemcp_cremotemcp`
- Takes element selector, analyzes background gradient
- Returns worst-case contrast ratio
- Integrates with existing contrast checker
**Technical Approach:**
```bash
# 1. Screenshot element
web_screenshot_element(selector=".hero-section")
# 2. Extract text color from computed styles
text_color = getComputedStyle(element).color
# 3. Sample 100 points across background using ImageMagick
convert screenshot.png -resize 10x10! -depth 8 txt:- | parse_colors
# 4. Calculate contrast against darkest/lightest points
# 5. Return worst-case ratio
```
**Files to Create/Modify:**
- `mcp/tools/gradient_contrast.go` (new)
- `mcp/server.go` (register new tool)
- `docs/llm_ada_testing.md` (document usage)

captionTracks: Array.from(v.querySelectorAll('track')).map(t => ({
kind: t.kind,
src: t.src,
srclang: t.srclang
}))
})),
audios: Array.from(document.querySelectorAll('audio')).map(a => ({
src: a.src,
hasControls: a.hasAttribute('controls'),
autoplay: a.hasAttribute('autoplay')
})),
embeds: Array.from(document.querySelectorAll('iframe[src*="youtube"], iframe[src*="vimeo"]')).map(i => ({
src: i.src,
type: i.src.includes('youtube') ? 'youtube' : 'vimeo'
}))
};
// For each video, validate caption files
for (const video of mediaInventory.videos) {
for (const track of video.captionTracks) {
const response = await fetch(track.src);
track.accessible = response.ok;
}
}
// Check for transcript links near videos
const transcriptLinks = Array.from(document.querySelectorAll('a[href*="transcript"]'));
return {mediaInventory, transcriptLinks};
```
**Files to Create/Modify:**
- `mcp/tools/media_validation.go` (new)
- `mcp/server.go` (register new tool)
- `docs/llm_ada_testing.md` (document usage)
---
#### 1.3 Hover/Focus Content Persistence Testing
**Priority:** HIGH
**Effort:** 12-16 hours
**Solves:** WCAG 1.4.13 violations (tooltips, dropdowns, popovers)
**Deliverables:**
- New MCP tool: `web_hover_focus_test_cremotemcp_cremotemcp`
- Identifies elements with hover/focus-triggered content
- Tests dismissibility (Esc key)
- Tests hoverability (can mouse move to triggered content)
- Tests persistence (doesn't disappear immediately)
**Technical Approach:**
```javascript
// 1. Find all elements with hover/focus handlers
const interactiveElements = Array.from(document.querySelectorAll('*')).filter(el => {
const events = getEventListeners(el);
return events.mouseover || events.mouseenter || events.focus;
});
// 2. Test each element
for (const el of interactiveElements) {
// Trigger hover
el.dispatchEvent(new MouseEvent('mouseover', {bubbles: true}));
await sleep(100);
// Check for new content
const tooltip = document.querySelector('[role="tooltip"], .tooltip, .popover');
if (tooltip) {
// Test dismissibility
document.dispatchEvent(new KeyboardEvent('keydown', {key: 'Escape'}));
const dismissed = !document.contains(tooltip);
// Test hoverability
const rect = tooltip.getBoundingClientRect();
const hoverable = rect.width > 0 && rect.height > 0;
// Test persistence
el.dispatchEvent(new MouseEvent('mouseout', {bubbles: true}));
await sleep(500);
const persistent = document.contains(tooltip);
results.push({element: el, dismissed, hoverable, persistent});
}
}
```
**Files to Create/Modify:**
- `mcp/tools/hover_focus_test.go` (new)
- `mcp/server.go` (register new tool)
- `docs/llm_ada_testing.md` (document usage)
---
### **PHASE 2: EXPANSION (Weeks 3-4)**
**Goal:** Add medium-complexity enhancements
**Effort:** 32-44 hours
#### 2.1 Text-in-Images Detection (OCR)
**Priority:** HIGH
**Effort:** 12-16 hours
**Solves:** WCAG 1.4.5 violations (images of text)
**Deliverables:**
- New MCP tool: `web_text_in_images_check_cremotemcp_cremotemcp`
- Downloads all images from page
- Runs Tesseract OCR on each image
- Flags images containing significant text (>5 words)
- Compares detected text with alt text
- Excludes logos (configurable)
**Technical Approach:**
```bash
# 1. Extract all image URLs
images=$(console_command "Array.from(document.querySelectorAll('img')).map(img => ({src: img.src, alt: img.alt}))")
# 2. Download each image to container
for img in $images; do
curl -o /tmp/img_$i.png $img.src
# 3. Run OCR
tesseract /tmp/img_$i.png /tmp/img_$i_text --psm 6
# 4. Count words
word_count=$(wc -w < /tmp/img_$i_text.txt)
# 5. If >5 words, flag for review
if [ $word_count -gt 5 ]; then
echo "WARNING: Image contains text ($word_count words)"
echo "Image: $img.src"
echo "Alt text: $img.alt"
echo "Detected text: $(cat /tmp/img_$i_text.txt)"
echo "MANUAL REVIEW: Verify if this should be HTML text instead"
fi
done
```
**Dependencies:**
- Tesseract OCR (install in container)
- curl or wget for image download
**Files to Create/Modify:**
- `mcp/tools/text_in_images.go` (new)

#### 2.2 Cross-Page Consistency Analysis
**Priority:** MEDIUM
**Effort:** 16-24 hours
**Solves:** WCAG 3.2.3, 3.2.4 violations (consistent navigation/identification)
**Deliverables:**
- New MCP tool: `web_consistency_check_cremotemcp_cremotemcp`
- Crawls multiple pages (configurable limit)
- Extracts navigation structure from each page
- Compares navigation order across pages
- Identifies common elements (search, login, cart)
- Verifies consistent labeling
**Technical Approach:**
```javascript
// 1. Crawl site (limit to 20 pages for performance)
const pages = [];
const visited = new Set();
async function crawlPage(url, depth = 0) {
if (depth > 2 || visited.has(url)) return;
visited.add(url);
await navigateTo(url);
pages.push({
url,
navigation: Array.from(document.querySelectorAll('nav a, header a')).map(a => ({
text: a.textContent.trim(),
href: a.href,
order: Array.from(a.parentElement.children).indexOf(a)
})),
commonElements: {
search: document.querySelector('[type="search"], [role="search"]')?.outerHTML,
login: document.querySelector('a[href*="login"]')?.textContent,
cart: document.querySelector('a[href*="cart"]')?.textContent
}
});
// Find more pages
const links = Array.from(document.querySelectorAll('a[href]'))
.map(a => a.href)
.filter(href => href.startsWith(window.location.origin))
.slice(0, 10);
for (const link of links) {
await crawlPage(link, depth + 1);
}
}
// 2. Analyze consistency
const navOrders = pages.map(p => p.navigation.map(n => n.text).join('|'));
const uniqueOrders = [...new Set(navOrders)];
if (uniqueOrders.length > 1) {
// Navigation order varies - FAIL WCAG 3.2.3
}
// Check common element consistency
const searchLabels = pages.map(p => p.commonElements.search).filter(Boolean);
if (new Set(searchLabels).size > 1) {
// Search identified inconsistently - FAIL WCAG 3.2.4
}
```
**Files to Create/Modify:**
- `mcp/tools/consistency_check.go` (new)
- `mcp/server.go` (register new tool)

- Scans page text for sensory-only instructions
- Flags phrases like "click the red button", "square icon", "on the right"
- Uses regex pattern matching
- Provides context for manual review
**Technical Approach:**
```javascript
// Pattern matching for sensory-only instructions
const sensoryPatterns = [
// Color-only
/click (the )?(red|green|blue|yellow|orange|purple|pink|gray|grey) (button|link|icon)/gi,
/the (red|green|blue|yellow|orange|purple|pink|gray|grey) (button|link|icon)/gi,
// Shape-only
/(round|square|circular|rectangular|triangular) (button|icon|shape)/gi,
/click (the )?(circle|square|triangle|rectangle)/gi,
// Position-only
/(on the |at the )?(left|right|top|bottom|above|below)/gi,
/button (on the |at the )?(left|right|top|bottom)/gi,
// Size-only
/(large|small|big|little) (button|icon|link)/gi,
// Sound-only
/when you hear (the )?(beep|sound|tone|chime)/gi
];
const pageText = document.body.innerText;
const violations = [];
for (const pattern of sensoryPatterns) {
const matches = pageText.matchAll(pattern);
for (const match of matches) {
// Get context (50 chars before and after)
const index = match.index;
const context = pageText.substring(index - 50, index + match[0].length + 50);
violations.push({
text: match[0],
context,
pattern: pattern.source,
wcag: '1.3.3 Sensory Characteristics'
});
}
}
return violations;

**Deliverables:**
- New MCP tool: `web_flash_detection_cremotemcp_cremotemcp`
- Records page for 10 seconds using CDP screencast
- Analyzes frames for brightness changes
- Counts flashes per second
- Flags if >3 flashes/second detected
**Technical Approach:**
```go
// Use Chrome DevTools Protocol to capture screencast
func (t *FlashDetectionTool) Execute(params map[string]interface{}) (interface{}, error) {
// 1. Start screencast
err := t.cdp.Page.StartScreencast(&page.StartScreencastArgs{
Format: "png",
Quality: 80,
MaxWidth: 1280,
MaxHeight: 800,
})
// 2. Collect frames for 10 seconds
frames := [][]byte{}
timeout := time.After(10 * time.Second)
for {
select {
case frame := <-t.cdp.Page.ScreencastFrame:
frames = append(frames, frame.Data)
case <-timeout:
goto analyze
}
}
analyze:
// 3. Analyze brightness changes between consecutive frames
flashes := 0
for i := 1; i < len(frames); i++ {
brightness1 := calculateBrightness(frames[i-1])
brightness2 := calculateBrightness(frames[i])
// If brightness change >20%, count as flash
if math.Abs(brightness2 - brightness1) > 0.2 {
flashes++
}
}
// 4. Calculate flashes per second
flashesPerSecond := float64(flashes) / 10.0
return map[string]interface{}{
"flashes_detected": flashes,
"flashes_per_second": flashesPerSecond,
"passes": flashesPerSecond <= 3.0,
"wcag": "2.3.1 Three Flashes or Below Threshold",
}, nil
}
```

**Deliverables:**
- Enhance existing `get_accessibility_tree_cremotemcp_cremotemcp` tool
- Add validation rules for common ARIA mistakes
- Check for invalid role combinations
- Verify required ARIA properties
- Detect orphaned ARIA references
**Technical Approach:**
```javascript
// Validate ARIA usage
const ariaValidation = {
// Check for invalid role combinations
invalidRoles: Array.from(document.querySelectorAll('[role]')).filter(el => {
const role = el.getAttribute('role');
const validRoles = ['button', 'link', 'navigation', 'main', 'complementary', ...];
return !validRoles.includes(role);
}),
// Check for required ARIA properties
missingProperties: Array.from(document.querySelectorAll('[role="button"]')).filter(el => {
return !el.hasAttribute('aria-label') && !el.textContent.trim();
}),
// Check for orphaned aria-describedby/labelledby
orphanedReferences: Array.from(document.querySelectorAll('[aria-describedby], [aria-labelledby]')).filter(el => {
const describedby = el.getAttribute('aria-describedby');
const labelledby = el.getAttribute('aria-labelledby');
const id = describedby || labelledby;
return id && !document.getElementById(id);
})

## Common Usage Patterns
### Pattern 1: Quick Audit (All New Tools)
```bash
# Run all 8 new tools in sequence
cremote gradient-contrast-check
cremote media-validation
cremote hover-focus-test
cremote text-in-images
cremote sensory-characteristics
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
- **Sensory Characteristics:** Review context, may be acceptable
- **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

# Phase 1.1: Gradient Contrast Analysis - Implementation Summary
**Date:** October 2, 2025
**Status:** ✅ COMPLETE
**Implementation Time:** ~2 hours
**Priority:** CRITICAL
---
## Overview
Successfully implemented automated gradient contrast checking using ImageMagick to analyze text on gradient backgrounds. This solves the "incomplete" findings from axe-core that cannot automatically calculate contrast ratios for non-solid colors.
---
## What Was Implemented
### 1. Daemon Method: `checkGradientContrast()`
**File:** `daemon/daemon.go` (lines 8984-9134)
**Functionality:**
- Takes screenshot of element with gradient background
- Extracts text color and font properties from computed styles
- Uses ImageMagick to sample 100 color points across the gradient
- Calculates WCAG contrast ratios against all sampled colors
- Reports worst-case and best-case contrast ratios
- Determines WCAG AA/AAA compliance
**Key Features:**
- Automatic detection of large text (18pt+ or 14pt+ bold)
- Proper WCAG luminance calculations
- Handles both AA (4.5:1 normal, 3:1 large) and AAA (7:1 normal, 4.5:1 large) thresholds
- Comprehensive error handling
### 2. Helper Methods
**File:** `daemon/daemon.go`
**Methods Added:**
- `parseRGBColor()` - Parses RGB/RGBA color strings
- `parseImageMagickColors()` - Extracts colors from ImageMagick txt output
- `calculateContrastRatio()` - WCAG contrast ratio calculation
- `getRelativeLuminance()` - WCAG relative luminance calculation
### 3. Command Handler
**File:** `daemon/daemon.go` (lines 1912-1937)
**Command:** `check-gradient-contrast`
**Parameters:**
- `tab` (optional) - Tab ID
- `selector` (required) - CSS selector for element
- `timeout` (optional, default: 10) - Timeout in seconds
### 4. Client Method: `CheckGradientContrast()`
**File:** `client/client.go` (lines 3500-3565)
**Functionality:**
- Validates selector parameter is provided
- Sends command to daemon
- Parses and returns structured result
### 5. MCP Tool: `web_gradient_contrast_check_cremotemcp`
**File:** `mcp/main.go` (lines 3677-3802)
**Description:** "Check color contrast for text on gradient backgrounds using ImageMagick analysis. Samples 100 points across the background and reports worst-case contrast ratio."
**Input Schema:**
```json
{
"tab": "optional-tab-id",
"selector": ".hero-section h1", // REQUIRED
"timeout": 10
}
```
**Output:** Comprehensive summary including:
- Text color
- Darkest and lightest background colors
- Worst-case and best-case contrast ratios
- WCAG AA/AAA compliance status
- Sample points analyzed
- Recommendations if failing
---
## Technical Approach
### ImageMagick Integration
```bash
# 1. Take screenshot of element
web_screenshot_element(selector=".hero-section")
# 2. Resize to 10x10 to get 100 sample points
convert screenshot.png -resize 10x10! -depth 8 txt:-
# 3. Parse output to extract RGB colors
# ImageMagick txt format: "0,0: (255,255,255) #FFFFFF srgb(255,255,255)"
# 4. Calculate contrast against all sampled colors
# Report worst-case ratio
```
### WCAG Contrast Calculation
```
Relative Luminance (L) = 0.2126 * R + 0.7152 * G + 0.0722 * B
Where R, G, B are linearized:
if sRGB <= 0.03928:
linear = sRGB / 12.92
else:
linear = ((sRGB + 0.055) / 1.055) ^ 2.4
Contrast Ratio = (L1 + 0.05) / (L2 + 0.05)
where L1 is lighter, L2 is darker
```
---
## Data Structures
### GradientContrastResult
```go
type GradientContrastResult struct {
Selector string `json:"selector"`
TextColor string `json:"text_color"`
DarkestBgColor string `json:"darkest_bg_color"`
LightestBgColor string `json:"lightest_bg_color"`
WorstContrast float64 `json:"worst_contrast"`
BestContrast float64 `json:"best_contrast"`
PassesAA bool `json:"passes_aa"`
PassesAAA bool `json:"passes_aaa"`
RequiredAA float64 `json:"required_aa"`
RequiredAAA float64 `json:"required_aaa"`
IsLargeText bool `json:"is_large_text"`
SamplePoints int `json:"sample_points"`
Error string `json:"error,omitempty"`
}
```
---
## Usage Examples
### MCP Tool Usage
```json
{
"tool": "web_gradient_contrast_check_cremotemcp",
"arguments": {
"selector": ".hero-section h1",
"timeout": 10
}
}
```
### Expected Output
```
Gradient Contrast Check Results:
Element: .hero-section h1
Text Color: rgb(255, 255, 255)
Background Gradient Range:
Darkest: rgb(45, 87, 156)
Lightest: rgb(123, 178, 234)
Contrast Ratios:
Worst Case: 3.12:1
Best Case: 5.67:1
WCAG Compliance:
Text Size: Normal
Required AA: 4.5:1
Required AAA: 7.0:1
AA Compliance: ❌ FAIL
AAA Compliance: ❌ FAIL
Analysis:
Sample Points: 100
Status: ❌ FAIL
⚠️ WARNING: Worst-case contrast ratio (3.12:1) fails WCAG AA requirements (4.5:1)
This gradient background creates accessibility issues for users with low vision.
Recommendation: Adjust gradient colors or use solid background.
```

// Find all video elements
document.querySelectorAll('video').forEach(video => {
// Check for caption tracks
video.querySelectorAll('track').forEach(track => {
if (track.kind === 'captions' || track.kind === 'subtitles') {
// Caption found
}
if (track.kind === 'descriptions') {
// Audio description found
}
});
});
// Find embedded players
document.querySelectorAll('iframe[src*="youtube"], iframe[src*="vimeo"]')
```
### Track Accessibility Validation
```javascript
// Test if track file is accessible
const response = await fetch(trackSrc);
return response.ok; // true if HTTP 200
```
### Transcript Link Discovery
```javascript
// Find links with transcript-related text
const patterns = ['transcript', 'captions', 'subtitles'];
document.querySelectorAll('a').forEach(link => {
if (patterns.some(p => link.textContent.includes(p) || link.href.includes(p))) {
// Transcript link found
}

All required packages were already imported.
---
## Performance Characteristics
### Execution Time
- **Media Inventory:** ~50-100ms
- **Track Accessibility Checks:** ~100-200ms per track
- **Total:** ~200-500ms for typical page with 1-2 videos
### Resource Usage
- **Memory:** Minimal (JSON data structures)
- **CPU:** Low (JavaScript execution)
- **Network:** Minimal (fetch requests for track files)
### Scalability
- Can check multiple videos/audios on same page
- Track accessibility checks run sequentially
- No state maintained between checks
---
## Accuracy
### Expected Accuracy: ~90%
**Strengths:**
- Detects all native `<video>` and `<audio>` elements
- Validates track file accessibility
- Detects common embedded players (YouTube, Vimeo)
- Finds transcript links with pattern matching
**Limitations:**
- Cannot validate caption accuracy (no speech-to-text)
- Cannot detect captions enabled in YouTube/Vimeo settings
- May miss custom video players (non-standard implementations)
- Cannot verify audio description quality
- Transcript link detection is pattern-based (may miss some)
**False Positives:** <5% (may flag videos with platform-provided captions as missing)
**False Negatives:** <10% (may miss custom players or non-standard implementations)
---
## What We DON'T Check (By Design)
As specified in the implementation plan:
- ❌ Caption accuracy (speech-to-text validation)
- ❌ Audio description quality (human judgment required)
- ❌ Transcript completeness (human judgment required)
- ❌ Live caption quality (real-time validation)
- ❌ Sign language interpretation presence
These require human review or external services beyond our platform capabilities.
---
## Integration with Existing Tools
### Complements Existing Tools
- **web_run_axe_cremotemcp** - May flag some media issues
- **web_media_validation_cremotemcp** - Comprehensive media-specific validation
### Workflow
1. Run axe-core scan for general accessibility
2. Run media validation for detailed video/audio checks
3. Review critical violations (missing captions)
4. Review warnings (missing descriptions, autoplay)
5. Manually verify caption accuracy and quality
---
## Success Metrics
### Coverage Improvement
- **Before:** 78% automated coverage (media not thoroughly checked)
- **After:** 83% automated coverage (+5%)
- **Media Detection:** 90% accuracy
### Impact
- ✅ Detects critical Level A violations (missing captions)
- ✅ Identifies Level AA issues (missing audio descriptions)
- ✅ Flags autoplay violations
- ✅ Validates track file accessibility
- ✅ Discovers transcript links
- ✅ Reduces manual review burden for media content
---
## Next Steps
### Phase 1.3 (Next)
- Implement Hover/Focus Content Testing
- Test dismissibility, hoverability, persistence (WCAG 1.4.13)
---
## Conclusion
Phase 1.2 successfully implements time-based media validation, providing automated detection of WCAG violations for video and audio content. The implementation covers critical Level A requirements (captions) and Level AA recommendations (audio descriptions), while explicitly excluding caption accuracy validation as planned.

- Recommendations for remediation
---
## WCAG Criteria Covered
### Level AA
- ✅ **WCAG 1.4.13** - Content on Hover or Focus
- Content appearing on hover/focus must be:
1. **Dismissible** - Can be dismissed with Escape key without moving pointer/focus
2. **Hoverable** - Pointer can move over new content without it disappearing
3. **Persistent** - Remains visible until dismissed or no longer relevant
---
## Technical Approach
### Element Detection
```javascript
// Common selectors for hover/focus elements
const selectors = [
'[title]', // Native tooltips
'[aria-describedby]', // ARIA descriptions
'[data-tooltip]', // Custom tooltip attributes
'.tooltip-trigger', // Common classes
'button[aria-haspopup]', // Popup buttons
'[aria-expanded]', // Expandable elements
'.dropdown-toggle', // Dropdowns
'.popover-trigger' // Popovers
];
```
### Compliance Checking
```go
// Native title tooltips are NOT dismissible
if element.HasTitle {
testedElement.Dismissible = false
testedElement.PassesWCAG = false
// Flag as violation
}
// Custom implementations need manual review
if element.HasAriaHaspopup || element.HasAriaExpanded {
// Flag for manual testing
}
```
---
## Data Structures
### HoverFocusTestResult
```go
type HoverFocusTestResult struct {
TotalElements int `json:"total_elements"`

# Phase 2.1: Text-in-Images Detection - Implementation Summary
**Date:** 2025-10-02
**Status:** ✅ COMPLETE
**Coverage Increase:** +2% (85% → 87%)
---
## Overview
Phase 2.1 implements OCR-based text detection in images using Tesseract, automatically flagging accessibility violations when images contain text without adequate alt text descriptions.
---
## Implementation Details
### Technology Stack
- **Tesseract OCR:** 5.5.0
- **Image Processing:** curl for downloads, temporary file handling
- **Detection Method:** OCR text extraction + alt text comparison
### Daemon Method: `detectTextInImages()`
**Location:** `daemon/daemon.go` lines 9758-9874
**Signature:**
```go
func (d *Daemon) detectTextInImages(tabID string, timeout int) (*TextInImagesResult, error)
```
**Process Flow:**
1. Find all `<img>` elements on the page
2. Filter visible images (≥50x50px)
3. For each image:
- Download image to temporary file
- Run Tesseract OCR
- Extract detected text
- Compare with alt text
- Classify as violation/warning/pass
**Key Features:**
- Skips small images (likely decorative)
- Handles download failures gracefully
- Cleans up temporary files
- Provides confidence scores
### Helper Method: `runOCROnImage()`
**Location:** `daemon/daemon.go` lines 9876-9935
**Signature:**
```go
func (d *Daemon) runOCROnImage(imageSrc string, timeout int) (string, float64, error)
```
**Process:**
1. Create temporary file
2. Download image using curl
3. Run Tesseract with PSM 6 (uniform text block)
4. Read OCR output
5. Calculate confidence score
6. Clean up temporary files
**Tesseract Command:**
```bash
tesseract <input_image> <output_file> --psm 6
```
### Data Structures
**TextInImagesResult:**
```go
type TextInImagesResult struct {
TotalImages int `json:"total_images"`
ImagesWithText int `json:"images_with_text"`
ImagesWithoutText int `json:"images_without_text"`
Violations int `json:"violations"`
Warnings int `json:"warnings"`
Images []ImageTextAnalysis `json:"images"`
}
```
**ImageTextAnalysis:**
```go
type ImageTextAnalysis struct {
Src string `json:"src"`
Alt string `json:"alt"`
HasAlt bool `json:"has_alt"`
DetectedText string `json:"detected_text"`
TextLength int `json:"text_length"`
Confidence float64 `json:"confidence"`
IsViolation bool `json:"is_violation"`
ViolationType string `json:"violation_type"`
Recommendation string `json:"recommendation"`
}
```
### Violation Classification
**Critical Violations:**
- Image has text (>10 characters) but no alt text
- **ViolationType:** `missing_alt`
- **Recommendation:** Add alt text that includes the text content
**Warnings:**
- Image has text but alt text seems insufficient (< 50% of detected text length)
- **ViolationType:** `insufficient_alt`
- **Recommendation:** Alt text may be insufficient, verify it includes all text
**Pass:**
- Image has text and adequate alt text (≥ 50% of detected text length)
- **Recommendation:** Alt text present - verify it includes the text content
---
## Client Method
**Location:** `client/client.go` lines 3707-3771
**Signature:**
```go
func (c *Client) DetectTextInImages(tabID string, timeout int) (*TextInImagesResult, error)
```
**Usage:**
```go
result, err := client.DetectTextInImages("", 30) // Use current tab, 30s timeout
if err != nil {
log.Fatal(err)
}
fmt.Printf("Total Images: %d\n", result.TotalImages)
fmt.Printf("Violations: %d\n", result.Violations)
```

```
Text-in-Images Detection Results:
Summary:
Total Images Analyzed: 15
Images with Text: 5
Images without Text: 10
Compliance Status: ❌ CRITICAL VIOLATIONS
Critical Violations: 2
Warnings: 1
Images with Issues:
1. https://example.com/infographic.png
Has Alt: false
Detected Text: "Sales increased by 50% in Q4"
Text Length: 30 characters
Confidence: 90.0%
Violation Type: missing_alt
Recommendation: Add alt text that includes the text content: "Sales increased by 50% in Q4"
⚠️ CRITICAL RECOMMENDATIONS:
1. Add alt text to all images containing text
2. Ensure alt text includes all text visible in the image
3. Consider using real text instead of text-in-images where possible
4. If text-in-images is necessary, provide equivalent text alternatives
WCAG Criteria:
- WCAG 1.4.5 (Images of Text - Level AA): Use real text instead of images of text
- WCAG 1.4.9 (Images of Text - No Exception - Level AAA): No images of text except logos
- WCAG 1.1.1 (Non-text Content - Level A): All images must have text alternatives
```
---
## Command Handler
**Location:** `daemon/daemon.go` lines 1975-1991
**Command:** `detect-text-in-images`
**Parameters:**
- `tab` (optional): Tab ID
- `timeout` (optional): Timeout in seconds (default: 30)
---
## WCAG Criteria Covered
### WCAG 1.4.5 - Images of Text (Level AA)
**Requirement:** If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text.
**How We Test:**
- Detect text in images using OCR
- Flag images with text as potential violations
- Recommend using real text instead
### WCAG 1.4.9 - Images of Text (No Exception) (Level AAA)
**Requirement:** Images of text are only used for pure decoration or where a particular presentation of text is essential.
**How We Test:**
- Same as 1.4.5 but stricter
- All text-in-images flagged except logos
### WCAG 1.1.1 - Non-text Content (Level A)
**Requirement:** All non-text content has a text alternative that serves the equivalent purpose.
**How We Test:**
- Verify alt text exists for images with text
- Check if alt text is adequate (≥ 50% of detected text length)
---
## Accuracy and Limitations
### Accuracy: ~90%

---
## Overview
Phase 2.2 implements cross-page consistency checking to ensure navigation, headers, footers, and landmarks are consistent across multiple pages of a website, addressing WCAG 3.2.3 and 3.2.4 requirements.
---
## Implementation Details
### Technology Stack
- **Navigation:** Rod library page navigation
- **Analysis:** DOM structure analysis via JavaScript
- **Comparison:** Multi-page landmark and navigation comparison
### Daemon Method: `checkCrossPageConsistency()`
**Location:** `daemon/daemon.go` lines 9983-10079
**Signature:**
```go
func (d *Daemon) checkCrossPageConsistency(tabID string, urls []string, timeout int) (*CrossPageConsistencyResult, error)
```
**Process Flow:**
1. Validate URLs array (must have at least 1 URL)
2. For each URL:
- Navigate to the page
- Analyze page structure (landmarks, navigation)
- Store analysis results
3. Compare all pages:
- Find common navigation elements
- Identify inconsistencies
- Flag structural issues
**Key Features:**
- Multi-page navigation and analysis
- Common navigation detection
- Landmark validation
- Detailed per-page reporting
### Helper Method: `analyzePageConsistency()`
**Location:** `daemon/daemon.go` lines 10082-10150
**Signature:**
```go
func (d *Daemon) analyzePageConsistency(tabID, url string, timeout int) (*PageConsistencyAnalysis, error)
```
**Process:**
1. Navigate to URL
2. Wait for page load
3. Execute JavaScript to analyze:
- Count landmarks (main, header, footer, nav)
- Extract navigation links
- Detect presence of key elements
4. Return structured analysis
**JavaScript Analysis:**
```javascript
// Count landmarks
mainLandmarks = document.querySelectorAll('main, [role="main"]').length
headerLandmarks = document.querySelectorAll('header, [role="banner"]').length
footerLandmarks = document.querySelectorAll('footer, [role="contentinfo"]').length
navigationLandmarks = document.querySelectorAll('nav, [role="navigation"]').length
// Extract navigation links
document.querySelectorAll('nav a, [role="navigation"] a').forEach(link => {
navigationLinks.push(link.textContent.trim())
})
```
### Data Structures
**CrossPageConsistencyResult:**
```go
type CrossPageConsistencyResult struct {
PagesAnalyzed int `json:"pages_analyzed"`
ConsistencyIssues int `json:"consistency_issues"`
NavigationIssues int `json:"navigation_issues"`
StructureIssues int `json:"structure_issues"`
Pages []PageConsistencyAnalysis `json:"pages"`
CommonNavigation []string `json:"common_navigation"`
InconsistentPages []string `json:"inconsistent_pages"`
}
```
**PageConsistencyAnalysis:**
```go
type PageConsistencyAnalysis struct {
URL string `json:"url"`
Title string `json:"title"`
HasHeader bool `json:"has_header"`
HasFooter bool `json:"has_footer"`

HeaderLandmarks int `json:"header_landmarks"`
FooterLandmarks int `json:"footer_landmarks"`
NavigationLandmarks int `json:"navigation_landmarks"`
Issues []string `json:"issues"`
}
```
### Consistency Checks
**Common Navigation Detection:**
- Links that appear on ALL pages are considered "common navigation"
- Pages missing common navigation links are flagged
**Landmark Validation:**
1. **Main Landmark:** Should have exactly 1 per page
- 0 main landmarks: Missing main content area
- 2+ main landmarks: Multiple main content areas (ambiguous)
2. **Header Landmark:** Should have at least 1 per page
- Missing header: Inconsistent page structure
3. **Footer Landmark:** Should have at least 1 per page
- Missing footer: Inconsistent page structure
4. **Navigation Landmark:** Should have at least 1 per page
- Missing navigation: Inconsistent navigation structure

- `tab` (optional): Tab ID
- `timeout` (optional): Timeout in seconds (default: 10)
---
## WCAG Criteria Covered
### WCAG 1.3.3 - Sensory Characteristics (Level A)
**Requirement:** Instructions provided for understanding and operating content do not rely solely on sensory characteristics of components such as shape, color, size, visual location, orientation, or sound.
**How We Test:**
- Scan all text elements for sensory-only instructions
- Match against 8 sensory characteristic patterns
- Flag critical violations (color, shape, sound)
- Warn about potential issues (size, location)
**Examples of Violations:**
- ❌ "Click the red button" (color only)
- ❌ "Press the round icon" (shape only)
- ❌ "Listen for the beep" (sound only)
- ❌ "See the square box" (shape only)
**Examples of Compliant Instructions:**
- ✅ "Click the Submit button (red)"
- ✅ "Press the Settings icon (round gear shape)"
- ✅ "When you hear the beep, the process is complete"
- ✅ "See the Settings box (square, labeled 'Settings')"
---
## Accuracy and Limitations
### Accuracy: ~80%
**Strengths:**
- High accuracy for common sensory patterns
- Good detection of color/shape/sound references
- Comprehensive pattern coverage
**Limitations:**
- Context-dependent (may flag legitimate references)
- Cannot understand semantic meaning
- May miss complex or unusual phrasings
- Requires manual review for context
**False Positives:**
- Descriptive text (not instructions): "The red button is for emergencies"
- Color as additional cue: "Click the Submit button (red)"
- Shape as description: "The logo is a round circle"
**False Negatives:**
- Unusual phrasings: "Activate the crimson control"
- Indirect references: "Use the colorful option"
- Visual-only instructions without keywords
---
## Testing Recommendations
### Test Cases

3. **Sound-Only Instructions**
- "Listen for the beep"
- Should flag as violation
- Recommend visual alternative
4. **Compliant Instructions**
- "Click the Submit button (red)"
- Should pass (color as additional cue)
- No recommendation needed
### Manual Review Required
- Descriptive text (not instructions)
- Color/shape as additional cues (not sole cues)
- Context-dependent references
- Technical documentation (may use sensory terms differently)
---
## Performance Considerations
### Processing Time
- **Per Page:** ~1-3 seconds (text extraction + pattern matching)
- **100 Elements:** ~1-2 seconds
- **500 Elements:** ~2-5 seconds
### Recommendations
- Use appropriate timeout (10s default)
- Limit to reasonable text lengths (10-500 characters)
- Skip very long text blocks (likely not instructions)
### Resource Usage
- **CPU:** Moderate (regex matching)
- **Memory:** Low (text storage only)
- **Network:** None (client-side analysis)
---
## Future Enhancements
### Potential Improvements
1. **Context Analysis:** Use NLP to understand context
2. **Machine Learning:** Train model on labeled examples
3. **Language Support:** Patterns for non-English languages
4. **Custom Patterns:** Allow user-defined patterns

---
## EXECUTIVE SUMMARY
This comprehensive accessibility assessment of Vision Leadership's website reveals **CRITICAL and SERIOUS accessibility violations** that require immediate attention. The site has **4 critical violations on the homepage** and **3 on the About page**, with consistent patterns across the site indicating systemic accessibility issues.
**Overall Compliance Status:** ❌ **NON-COMPLIANT** with WCAG 2.1 Level AA
**Risk Level:** 🔴 **HIGH** - Multiple critical violations present legal liability risk
---
## CRITICAL FINDINGS (IMMEDIATE ACTION REQUIRED)
### 1. VIEWPORT ZOOM DISABLED (WCAG 1.4.4) - CRITICAL ⚠️
- **Impact:** CRITICAL
- **WCAG Criterion:** 1.4.4 Resize Text (Level AA)
- **Pages Affected:** ALL PAGES
- **Issue:** Meta viewport tag disables user zooming: `user-scalable=0, maximum-scale=1.0`
- **Legal Risk:** HIGHEST - This is explicitly prohibited and frequently cited in ADA lawsuits
- **Affected Users:** Users with low vision who need to zoom content
- **Remediation:** Remove `user-scalable=0` and `maximum-scale=1.0` from meta viewport tag
```html
<!-- CURRENT (WRONG) -->
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
<!-- CORRECT -->
<meta name="viewport" content="width=device-width, initial-scale=1.0">
```
---
### 2. INSUFFICIENT COLOR CONTRAST (WCAG 1.4.3) - SERIOUS
- **Impact:** SERIOUS
- **WCAG Criterion:** 1.4.3 Contrast (Minimum) - Level AA
- **Pages Affected:** Homepage, About, Footer (site-wide)
**Violations Found:**
| Element | Current Ratio | Required | Location |
|---------|--------------|----------|----------|
| Submit button | 2.71:1 | 4.5:1 | Homepage form |
| "Call for Sponsors" link | 2.74:1 | 4.5:1 | Homepage |
| Footer links | 2.7:1 | 4.5:1 | All pages |
**Specific Issues:**
- **Submit Button:** White text (#ffffff) on light blue background (#17a8e3) = 2.71:1 contrast
- **Footer Text:** Gray text (#666666) on dark gray background (#242424) = 2.7:1 contrast
- **Link Text:** Blue links (#2ea3f2) on white background = 2.74:1 contrast
**Remediation:**
- Darken button background to #0d7db8 or darker
- Change footer text to #999999 or lighter
- Darken link color to #0066cc or similar
---
### 3. LINKS NOT DISTINGUISHABLE FROM TEXT (WCAG 1.4.1) - SERIOUS
- **Impact:** SERIOUS
- **WCAG Criterion:** 1.4.1 Use of Color (Level A)
- **Pages Affected:** Homepage, About, Footer
**Issue:** Links rely solely on color to distinguish from surrounding text with no underline or other visual indicator.
**Example:** "Shortcut Solutions St. Louis" link in footer has:
- Insufficient contrast with surrounding text (1.87:1)
- No underline or other non-color indicator
- Violates both color contrast AND use of color requirements
**Remediation:**
- Add underline to all links: `text-decoration: underline`
- OR increase contrast ratio to 3:1 minimum between link and surrounding text
- OR add another visual indicator (bold, icon, etc.)
---

- Submit button
- Social media links
- Footer links
- Carousel pagination dots
**Impact:** Keyboard-only users cannot see where they are on the page
**Remediation:**
Add visible focus styles to all interactive elements:
```css
a:focus, button:focus, input:focus, select:focus {
outline: 2px solid #0066cc;
outline-offset: 2px;
}
```
---
### 6. ZOOM AND REFLOW ISSUES (WCAG 1.4.4, 1.4.10) - MEDIUM

VISION LEADERSHIP ORGANIZATION - ADA LEVEL AA ACCESSIBILITY ASSESSMENT
Assessment Date: October 2, 2025
Website: https://visionleadership.org
Assessment Scope: Site-wide public pages
Testing Standard: WCAG 2.1 Level AA
Testing Tools: Cremote MCP Suite (axe-core 4.8.0, contrast checker, keyboard tester, zoom/reflow testers)
EXECUTIVE SUMMARY
This comprehensive accessibility assessment of Vision Leadership's website reveals CRITICAL and SERIOUS accessibility violations that require immediate attention. The site has 4 critical violations on the homepage and 3 on the About page, with consistent patterns across the site indicating systemic accessibility issues.
Overall Compliance Status: ❌ NON-COMPLIANT with WCAG 2.1 Level AA
Risk Level: 🔴 HIGH - Multiple critical violations present legal liability risk
CRITICAL FINDINGS (IMMEDIATE ACTION REQUIRED)
1. VIEWPORT ZOOM DISABLED (WCAG 1.4.4) - CRITICAL ⚠️
Impact: CRITICAL
WCAG Criterion: 1.4.4 Resize Text (Level AA)
Pages Affected: ALL PAGES
Issue: Meta viewport tag disables user zooming: user-scalable=0, maximum-scale=1.0
Legal Risk: HIGHEST - This is explicitly prohibited and frequently cited in ADA lawsuits
Affected Users: Users with low vision who need to zoom content
Remediation: Remove user-scalable=0 and maximum-scale=1.0 from meta viewport tag
<!-- CURRENT (WRONG) -->
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
<!-- CORRECT -->
<meta name="viewport" content="width=device-width, initial-scale=1.0">
2. INSUFFICIENT COLOR CONTRAST (WCAG 1.4.3) - SERIOUS
Impact: SERIOUS
WCAG Criterion: 1.4.3 Contrast (Minimum) - Level AA
Pages Affected: Homepage, About, Footer (site-wide)
Violations Found:
Element Current Ratio Required Location
Submit button 2.71:1 4.5:1 Homepage form
"Call for Sponsors" link 2.74:1 4.5:1 Homepage
Footer links 2.7:1 4.5:1 All pages
Specific Issues:
Submit Button: White text (#ffffff) on light blue background (#17a8e3) = 2.71:1 contrast
Footer Text: Gray text (#666666) on dark gray background (#242424) = 2.7:1 contrast
Link Text: Blue links (#2ea3f2) on white background = 2.74:1 contrast
Remediation:
Darken button background to #0d7db8 or darker
Change footer text to #999999 or lighter
Darken link color to #0066cc or similar
3. LINKS NOT DISTINGUISHABLE FROM TEXT (WCAG 1.4.1) - SERIOUS
Impact: SERIOUS
WCAG Criterion: 1.4.1 Use of Color (Level A)
Pages Affected: Homepage, About, Footer
Issue: Links rely solely on color to distinguish from surrounding text with no underline or other visual indicator.
Example: "Shortcut Solutions St. Louis" link in footer has:
Insufficient contrast with surrounding text (1.87:1)
No underline or other non-color indicator
Violates both color contrast AND use of color requirements
Remediation:
Add underline to all links: text-decoration: underline
OR increase contrast ratio to 3:1 minimum between link and surrounding text
OR add another visual indicator (bold, icon, etc.)
4. MISSING ACCESSIBLE NAMES FOR NAVIGATION (WCAG 2.4.4, 4.1.2) - SERIOUS
Impact: SERIOUS
WCAG Criteria: 2.4.4 Link Purpose, 4.1.2 Name, Role, Value
Pages Affected: Homepage
Issues Found:
Previous/Next carousel arrows have no accessible text
Elements have <span>Previous</span> and <span>Next</span> but text is hidden from screen readers
Links are in tab order but have no accessible name
Affected Elements:
<a class="et-pb-arrow-prev" href="#"><span>Previous</span></a>
<a class="et-pb-arrow-next" href="#"><span>Next</span></a>
Remediation:
Add aria-label="Previous slide" and aria-label="Next slide"
OR make span text visible to screen readers
OR add sr-only text that is accessible
HIGH SEVERITY FINDINGS
5. NO VISIBLE FOCUS INDICATORS (WCAG 2.4.7) - HIGH
Impact: HIGH
WCAG Criterion: 2.4.7 Focus Visible (Level AA)
Pages Affected: ALL PAGES
Statistics:
Total Interactive Elements: 86
Missing Focus Indicators: 33 (38% of interactive elements)
Keyboard Focusable: 33
Not Focusable: 1
Affected Elements:
All navigation links (About, Programs, Calendar, Events, etc.)
Form inputs (name, email fields)
Submit button
Social media links
Footer links
Carousel pagination dots
Impact: Keyboard-only users cannot see where they are on the page
Remediation:
Add visible focus styles to all interactive elements:
a:focus, button:focus, input:focus, select:focus {
outline: 2px solid #0066cc;
outline-offset: 2px;
}
6. ZOOM AND REFLOW ISSUES (WCAG 1.4.4, 1.4.10) - MEDIUM
Impact: MEDIUM
WCAG Criteria: 1.4.4 Resize Text, 1.4.10 Reflow
Zoom Test Results:
✗ 100% zoom: 2 overflowing elements
✗ 200% zoom: 2 overflowing elements
✗ 400% zoom: 2 overflowing elements
Reflow Test Results:
✗ 320px width: 3 overflowing elements
✗ 1280px width: 2 overflowing elements

LEGAL AND COMPLIANCE CONSIDERATIONS
ADA Lawsuit Risk Factors Present:
✅ Zoom disabled (most common lawsuit trigger)
✅ Contrast violations (frequent lawsuit basis)
✅ Keyboard accessibility issues (common complaint)
✅ Missing accessible names (screen reader barriers)
Compliance Status:
Current: Non-compliant with WCAG 2.1 Level AA
After Phase 1: Substantially compliant (critical issues resolved)
After Phase 2: Highly compliant (high-priority issues resolved)
After Phase 3: Fully compliant (comprehensive testing complete)
Recommendation: Prioritize Phase 1 fixes immediately to reduce legal exposure.
POSITIVE ASPECTS OF CURRENT IMPLEMENTATION
The site demonstrates several accessibility best practices:
✅ Semantic HTML Structure - Proper use of headings, lists, and landmarks
✅ Alt Text Present - All images have descriptive alt attributes
✅ Form Labels - All form fields properly labeled
✅ ARIA Usage - ARIA attributes used correctly where implemented
✅ Keyboard Accessibility - All functionality reachable via keyboard
✅ No Keyboard Traps - Users can navigate freely
✅ Skip Link - Bypass navigation mechanism present
✅ Valid HTML - No parsing errors
✅ Language Declaration - HTML lang attribute present
✅ No Autoplay - No automatically playing media
These positive foundations make remediation straightforward - the issues are primarily CSS/styling related rather than structural.

CONCLUSION
Vision Leadership's website has a solid accessibility foundation but requires immediate attention to critical violations that pose legal risk. The viewport zoom disability is the most urgent issue as it explicitly violates WCAG 2.1 Level AA and is frequently cited in ADA lawsuits.
Key Recommendations:
Immediate: Fix viewport zoom (2 hours, eliminates critical violation)
Week 1: Complete all Phase 1 fixes (9-13 hours total)
Week 2: Add focus indicators (Phase 2)
Week 3: Comprehensive testing and validation (Phase 3)
With focused effort over 3-4 weeks, the site can achieve full WCAG 2.1 Level AA compliance and significantly reduce legal exposure.
