+# ADA Accessibility Testing Implementation Plan
+
+**Project:** Cremote MCP Accessibility Enhancements  
+**Created:** 2025-10-02  
+**Status:** Planning Phase  
+**Goal:** Enhance cremote MCP tools to support comprehensive automated ADA/WCAG accessibility testing
+
+## Executive Summary
+
+Based on ADA audit testing documented in `notes.md`, this plan addresses identified gaps in cremote's accessibility testing capabilities. The implementation will fix existing bugs, add new specialized testing tools, and integrate industry-standard accessibility testing libraries.
+
+**Current Coverage:** ~40% of WCAG 2.1 Level AA criteria  
+**Target Coverage:** ~60-70% of WCAG 2.1 Level AA criteria  
+
+---
+
+## Implementation Phases
+
+### Phase 1: Critical Bug Fixes (Week 1)
+**Goal:** Restore broken functionality
+
+#### Task 1: Fix web_page_info and web_viewport_info TypeError Bugs
+- **Status:** ✅ Complete
+- **Priority:** P0 - Critical
+- **Estimated Effort:** 4-6 hours
+- **Assignee:** AI Agent
+- **Dependencies:** None
+- **Completed:** 2025-10-02
+
+**Problem:**
+- Both tools fail with `TypeError: (intermediate value)(...).apply is not a function`
+- Blocks viewport testing and responsive design validation
+- Agent had to use console commands as workaround
+
+**Root Cause Analysis:**
+- IIFE syntax `(() => {...})()` was being passed directly to `page.Eval()`
+- Rod's `page.Eval()` expects a function expression, not an already-invoked function
+- The IIFE was trying to invoke itself before rod could evaluate it
+
+**Solution Implemented:**
+- Changed all IIFEs from `(() => {...})()` to function expressions `() => {...}`
+- Fixed in 4 functions: `getPageInfo`, `getViewportInfo`, `getPerformance`, `checkContent`
+- Rod's `page.Eval()` now properly invokes the function expressions
+
+**Implementation Steps:**
+1. [x] Reproduce the error in test environment
+2. [x] Analyze rod's page.Eval implementation and requirements
+3. [x] Test alternative JavaScript patterns (function expressions vs IIFEs)
+4. [x] Update getPageInfo and getViewportInfo JavaScript code
+5. [x] Update getPerformance JavaScript code
+6. [x] Update checkContent JavaScript code (all 7 cases)
+7. [x] Rebuild MCP server successfully
+
+**Files Modified:**
+- `daemon/daemon.go` - Fixed 4 functions with IIFE issues:
+  - `getPageInfo` (lines 4710-4728)
+  - `getViewportInfo` (lines 4794-4811)
+  - `getPerformance` (lines 4865-4908)
+  - `checkContent` (lines 4969-5073) - 7 cases fixed
+- `mcp/cremote-mcp` - Rebuilt successfully
+
+**Success Criteria:**
+- [x] web_page_info returns complete metadata without errors
+- [x] web_viewport_info returns viewport dimensions without errors
+- [x] getPerformance returns metrics without errors
+- [x] checkContent works for all content types
+- [x] MCP server builds successfully
+- [ ] Tested against live website (pending deployment)

+5. [x] Detect large text (18pt+ or 14pt bold+) for different thresholds
+6. [x] Create daemon command: `check-contrast`
+7. [x] Add client method: `CheckContrast()`
+8. [x] Create MCP tool: `web_contrast_check_cremotemcp`
+9. [x] Add comprehensive type structures
+
+**Technical Approach Implemented:**
+```javascript
+// Implemented WCAG contrast calculation
+function getLuminance(r, g, b) {
+  const rsRGB = r / 255;
+  const gsRGB = g / 255;
+  const bsRGB = b / 255;
+
+  const r2 = rsRGB <= 0.03928 ? rsRGB / 12.92 : Math.pow((rsRGB + 0.055) / 1.055, 2.4);
+  const g2 = gsRGB <= 0.03928 ? gsRGB / 12.92 : Math.pow((gsRGB + 0.055) / 1.055, 2.4);
+  const b2 = bsRGB <= 0.03928 ? bsRGB / 12.92 : Math.pow((bsRGB + 0.055) / 1.055, 2.4);
+
+  return 0.2126 * r2 + 0.7152 * g2 + 0.0722 * b2;
+}
+
+function getContrastRatio(fg, bg) {
+  const l1 = getLuminance(fg.r, fg.g, fg.b);
+  const l2 = getLuminance(bg.r, bg.g, bg.b);
+  const lighter = Math.max(l1, l2);
+  const darker = Math.min(l1, l2);
+  return (lighter + 0.05) / (darker + 0.05);
+}
+
+function getEffectiveBackground(element) {
+  let current = element;
+  while (current && current !== document.body.parentElement) {
+    const style = window.getComputedStyle(current);
+    const bgColor = style.backgroundColor;
+    const parsed = parseColor(bgColor);
+
+    if (parsed && parsed.a > 0) {
+      if (!(parsed.r === 0 && parsed.g === 0 && parsed.b === 0 && parsed.a === 0)) {
+        return bgColor;
+      }
+    }
+    current = current.parentElement;
+  }
+  return 'rgb(255, 255, 255)'; // Default to white
+}

+
+## Testing Workflows
+
+### Complete ADA Audit Workflow
+
+```bash
+# 1. Initial Setup
+cremote navigate --url https://example.com
+cremote screenshot --output baseline.png
+
+# 2. Automated Testing (Axe-Core)
+cremote inject-axe
+cremote run-axe --run-only wcag2a,wcag2aa,wcag21aa > axe-results.json
+
+# 3. Specialized Tests
+cremote contrast-check > contrast-results.txt
+cremote keyboard-test > keyboard-results.txt
+cremote zoom-test --zoom-levels 1.0,2.0,4.0 > zoom-results.txt
+cremote reflow-test --widths 320,1280 > reflow-results.txt
+
+# 4. Visual Documentation
+cremote screenshot --output zoom-200.png --zoom-level 2.0
+cremote screenshot --output mobile-320.png --width 320 --height 568
+cremote screenshot --output desktop-1280.png --width 1280 --height 720
+
+# 5. Accessibility Tree Analysis
+cremote get-accessibility-tree --include-contrast true > a11y-tree.json
+```
+
+### Quick Compliance Check
+
+```bash
+# Run all core tests in sequence
+cremote inject-axe && \
+cremote run-axe && \
+cremote contrast-check && \
+cremote keyboard-test && \
+cremote zoom-test && \
+cremote reflow-test
+```
+
+---
+
+## Best Practices
+
+### 1. Test Early and Often
+- Run automated tests during development
+- Integrate into CI/CD pipelines
+- Test on every significant UI change
+
+### 2. Combine Automated and Manual Testing
+- Use automated tools for ~70% coverage
+- Manually verify complex interactions
+- Test with actual assistive technologies
+
+### 3. Test Multiple Breakpoints
+```bash
+# Test common device sizes
+cremote reflow-test --widths 320,375,768,1024,1280,1920
+```
+
+### 4. Document Visual Issues
+```bash
+# Capture evidence of issues
+cremote screenshot --output issue-contrast.png
+cremote screenshot --output issue-zoom-400.png --zoom-level 4.0
+```
+
+### 5. Prioritize Violations
+- **Critical:** Axe violations with "critical" or "serious" impact
+- **High:** Contrast failures, keyboard traps, missing focus indicators
+- **Medium:** Zoom/reflow issues, incomplete axe checks
+- **Low:** Best practice recommendations
+
+---
+
+## Limitations
+
+### What These Tools Cannot Test
+
+1. **Semantic Meaning** - Tools can detect missing alt text but not if it's meaningful
+2. **Cognitive Load** - Cannot assess if content is easy to understand
+3. **Timing** - Cannot fully test time-based media or auto-updating content
+4. **Context** - Cannot determine if link text makes sense out of context
+5. **User Experience** - Cannot replace testing with real users and assistive technologies
+
+### Known Issues
+
+- **Contrast Detection:** May not accurately detect contrast on complex backgrounds (gradients, images)
+- **Keyboard Traps:** Detection is heuristic-based and may miss complex traps
+- **Dynamic Content:** Tests are point-in-time; may miss issues in SPAs or dynamic updates
+- **Shadow DOM:** Limited support for components using Shadow DOM

+
+## Tool Usage Patterns
+
+### Pattern 1: Initial Audit
+
+```json
+// Step 1: Inject axe-core
+{
+  "tool": "web_inject_axe_cremotemcp",
+  "arguments": {
+    "timeout": 30
+  }
+}
+
+// Step 2: Run comprehensive tests
+{
+  "tool": "web_run_axe_cremotemcp",
+  "arguments": {
+    "run_only": ["wcag2a", "wcag2aa", "wcag21aa"],
+    "timeout": 30
+  }
+}
+
+// Step 3: Analyze results and run specialized tests based on findings
+```
+
+### Pattern 2: Contrast-Specific Testing
+
+```json
+// For pages with known or suspected contrast issues
+{
+  "tool": "web_contrast_check_cremotemcp",
+  "arguments": {
+    "selector": "body",  // Test entire page
+    "timeout": 10
+  }
+}
+
+// For specific sections
+{
+  "tool": "web_contrast_check_cremotemcp",
+  "arguments": {
+    "selector": ".main-content",  // Test specific area
+    "timeout": 10
+  }
+}
+```
+
+### Pattern 3: Keyboard Navigation Testing
+
+```json
+{
+  "tool": "web_keyboard_test_cremotemcp",
+  "arguments": {
+    "timeout": 10
+  }
+}
+
+// Analyze output for:
+// - not_focusable: Elements that should be keyboard accessible but aren't
+// - no_focus_indicator: Elements missing visible focus indicators
+// - keyboard_trap: Elements that trap keyboard focus
+```
+
+### Pattern 4: Zoom and Responsive Testing
+
+```json
+// Test zoom levels (WCAG 1.4.4)
+{
+  "tool": "web_zoom_test_cremotemcp",
+  "arguments": {
+    "zoom_levels": [1.0, 2.0, 4.0],
+    "timeout": 10
+  }
+}
+
+// Test responsive breakpoints (WCAG 1.4.10)
+{
+  "tool": "web_reflow_test_cremotemcp",
+  "arguments": {
+    "widths": [320, 768, 1280],
+    "timeout": 10
+  }
+}
+```
+
+### Pattern 5: Visual Documentation
+
+```json
+// Capture baseline
+{
+  "tool": "web_screenshot_cremotemcp",
+  "arguments": {
+    "output": "/tmp/baseline.png",
+    "timeout": 5
+  }
+}
+
+// Capture at 200% zoom
+{
+  "tool": "web_screenshot_cremotemcp",
+  "arguments": {
+    "output": "/tmp/zoom-200.png",
+    "zoom_level": 2.0,
+    "timeout": 5
+  }
+}
+
+// Capture mobile view
+{
+  "tool": "web_screenshot_cremotemcp",
+  "arguments": {
+    "output": "/tmp/mobile-320.png",
+    "width": 320,
+    "height": 568,
+    "timeout": 5
+  }
+}
+```
+
+## Interpreting Results
+
+### Axe-Core Results
+
+```json
+{
+  "violations": [
+    {
+      "id": "color-contrast",
+      "impact": "serious",  // critical, serious, moderate, minor
+      "description": "Elements must have sufficient color contrast",
+      "nodes": [
+        {
+          "html": "<p class=\"text-gray\">Low contrast text</p>",
+          "target": [".text-gray"],
+          "failureSummary": "Fix any of the following:\n  Element has insufficient color contrast of 3.2:1 (foreground color: #808080, background color: #ffffff, font size: 12.0pt (16px), font weight: normal). Expected contrast ratio of 4.5:1"
+        }
+      ]
+    }
+  ],
+  "passes": [...],      // Tests that passed
+  "incomplete": [...],  // Tests requiring manual review
+  "inapplicable": [...]  // Tests not applicable to this page
+}
+```
+
+**Action Priority:**
+1. **Critical/Serious violations** - Fix immediately
+2. **Moderate violations** - Fix in current sprint
+3. **Minor violations** - Fix when convenient
+4. **Incomplete** - Manually review and test
+5. **Passes** - Document for compliance
+
+### Contrast Check Results
+
+```
+WCAG AA Violations:
+  - p:nth-of-type(3): 3.2:1 (required: 4.5:1)
+    Text: This text has insufficient contrast
+    Colors: rgb(128, 128, 128) on rgb(255, 255, 255)
+```
+
+**Remediation:**
+- Darken foreground color or lighten background
+- Use contrast ratio calculator to find compliant colors
+- Test with `web_contrast_check_cremotemcp` after fixes
+
+### Keyboard Test Results
+
+```
+High Severity Issues:
+  - not_focusable: Interactive element is not keyboard focusable
+    Element: div[role="button"]
+  - no_focus_indicator: Interactive element lacks visible focus indicator
+    Element: button.submit-btn
+```
+
+**Remediation:**
+- `not_focusable`: Add `tabindex="0"` or use semantic HTML (`<button>` instead of `<div>`)
+- `no_focus_indicator`: Add CSS `:focus` styles with visible outline/border
+- `keyboard_trap`: Review JavaScript event handlers and focus management
+
+### Zoom Test Results
+
+```
+Zoom 400% ✗ FAIL:
+  Horizontal Scroll: true
+  Overflowing Elements: 3
+  Text Readable: true
+```
+
+**Remediation:**
+- Use responsive units (rem, em, %) instead of fixed pixels
+- Implement CSS media queries for zoom levels
+- Test with `max-width: 100%` on images and containers
+
+### Reflow Test Results
+
+```
+320px Width ✗ FAIL:
+  Horizontal Scroll: true
+  Responsive Layout: false
+  Overflowing Elements: 5
+```
+
+**Remediation:**
+- Implement mobile-first responsive design
+- Use CSS Grid or Flexbox with `flex-wrap`
+- Test with `overflow-x: hidden` cautiously (may hide content)
+
+## Common Workflows
+
+### Workflow 1: New Page Audit
+
+```
+1. Navigate to page
+2. Run web_inject_axe_cremotemcp
+3. Run web_run_axe_cremotemcp with wcag2aa tags
+4. If violations found:
+   a. Run web_contrast_check_cremotemcp for contrast issues
+   b. Run web_keyboard_test_cremotemcp for keyboard issues
+5. Run web_zoom_test_cremotemcp
+6. Run web_reflow_test_cremotemcp
+7. Capture screenshots for documentation
+8. Generate report with all findings
+```
+
+### Workflow 2: Regression Testing
+
+```
+1. Navigate to page
+2. Run web_run_axe_cremotemcp
+3. Compare results with baseline
+4. If new violations:
+   a. Run specialized tests for affected areas
+   b. Capture screenshots showing issues
+5. Report regressions
+```
+
+### Workflow 3: Contrast-Focused Audit
+
+```
+1. Navigate to page
+2. Run web_contrast_check_cremotemcp on entire page
+3. For each violation:
+   a. Capture screenshot of affected element
+   b. Document current and required contrast ratios
+   c. Suggest color adjustments
+4. After fixes, re-run web_contrast_check_cremotemcp
+5. Verify all violations resolved
+```
+
+### Workflow 4: Keyboard Accessibility Audit
+
+```
+1. Navigate to page
+2. Run web_keyboard_test_cremotemcp
+3. Analyze tab order for logical sequence
+4. For each issue:
+   a. Document element and issue type
+   b. Suggest remediation (tabindex, semantic HTML, focus styles)
+5. After fixes, re-run web_keyboard_test_cremotemcp
+6. Manually verify complex interactions
+```
+
+## Error Handling
+
+### Common Errors and Solutions
+
+**Error:** "Failed to inject library"
+```
+Solution: Check network connectivity, try alternative CDN, or increase timeout
+```
+
+**Error:** "Evaluation timed out"
+```
+Solution: Increase timeout parameter, test on smaller page sections
+```
+
+**Error:** "No tab available"
+```
+Solution: Navigate to a page first using web_navigate_cremotemcp
+```
+
+**Error:** "Failed to get page"
+```
+Solution: Verify tab ID is valid, check if page is still loaded
+```
+
+## Best Practices for LLM Agents
+
+### 1. Always Start with Axe-Core
+Axe-core provides the broadest coverage (~57% of WCAG 2.1 AA). Use it as the foundation, then run specialized tests based on findings.
+
+### 2. Test in Logical Order
+```
+Automated (axe) → Specialized (contrast, keyboard) → Visual (zoom, reflow) → Documentation (screenshots)
+```
+
+### 3. Provide Context in Reports
+When reporting issues, include:
+- WCAG criterion violated
+- Severity/impact level
+- Specific element(s) affected
+- Current state (e.g., contrast ratio 3.2:1)
+- Required state (e.g., contrast ratio 4.5:1)
+- Suggested remediation
+
+### 4. Capture Evidence
+Always capture screenshots when documenting issues:
+```json
+{
+  "tool": "web_screenshot_cremotemcp",
+  "arguments": {
+    "output": "/tmp/issue-contrast-button.png"
+  }
+}
+```
+
+### 5. Verify Fixes
+After suggesting fixes, re-run the relevant tests to verify resolution:
+```
+1. Suggest fix
+2. Wait for implementation
+3. Re-run specific test
+4. Confirm issue resolved
+```
+
+### 6. Know the Limitations
+These tools cannot test:
+- Semantic meaning of content
+- Cognitive load
+- Time-based media (captions, audio descriptions)
+- Complex user interactions
+- Context-dependent issues
+
+Always recommend manual testing with assistive technologies for comprehensive audits.
+
+## Integration with Development Workflow
+
+### Pre-Commit Testing
+```bash
+# Run quick accessibility check before commit
+cremote inject-axe && cremote run-axe --run-only wcag2aa
+```
+
+### CI/CD Integration
+```yaml
+# Run full accessibility suite in CI
+- cremote inject-axe
+- cremote run-axe > axe-results.json
+- cremote contrast-check > contrast-results.txt
+- cremote keyboard-test > keyboard-results.txt
+- cremote zoom-test > zoom-results.txt
+- cremote reflow-test > reflow-results.txt
+```
+
+### Pull Request Reviews
+```
+1. Run accessibility tests on PR branch
+2. Compare with main branch baseline
+3. Report new violations in PR comments
+4. Block merge if critical violations found
+```
+
+## Quick Command Reference
+
+```bash
+# Inject axe-core
+cremote inject-axe
+
+# Run comprehensive tests
+cremote run-axe --run-only wcag2a,wcag2aa,wcag21aa

+
+
+SPECIFIC TOOL IMPROVEMENTS NEEDED
+
+1. FIX EXISTING TOOL BUGS
+
+❌ web_page_info_cremotemcp_cremotemcp - TypeError bug
+❌ web_viewport_info_cremotemcp_cremotemcp - TypeError bug
+
+Recommendation: Report to cremotemcp developers
+
+2. ADD NEW TOOLS
+
+🆕 web_contrast_check_cremotemcp - Automated contrast testing
+🆕 web_keyboard_test_cremotemcp - Automated keyboard navigation
+🆕 web_zoom_test_cremotemcp - Automated zoom testing
+🆕 web_reflow_test_cremotemcp - Automated reflow testing
+🆕 web_inject_axe_cremotemcp - Inject axe-core for comprehensive testing
+
+3. ENHANCED EXISTING TOOLS
+
+✨ console_command - Add ability to inject external libraries (axe-core)
+✨ web_screenshot - Add zoom level parameter
+✨ web_screenshot - Add viewport size parameter
+✨ get_accessibility_tree - Add contrast ratio data
+
+WHAT I ACCOMPLISHED:
+
+  	* ✅ Comprehensive automated testing (40% of WCAG criteria)
+  	* ✅ Identified critical issues (skip link, heading structure)
+  	* ✅ Verified excellent form accessibility
+  	* ✅ Professional documentation
+
+ALL THE DETAILS:
+
+You can review, but they're basicaly js bugs in the tool. May not need a 
+"fix" because the agent used the console as a work around to get these 
+two items info we needed for reporting.
+
+1. WEB_PAGE_INFO_CREMOTEMCP_CREMOTEMCP
+
+Error: TypeError: (intermediate value)(...).apply is not a function
+
+// Attempted to get comprehensive page metadata
+web_page_info_cremotemcp_cremotemcp(url: 
+"https://visionleadership.org/")
+
+What Failed:
+
+  	* The tool's internal JavaScript execution encountered a syntax error
+  	* Likely an issue with the tool's implementation using .apply() on an 
+undefined function
+  	* This is a bug in the cremotemcp tool itself, not the website
+
+Impact:
+
+  	* Could not automatically retrieve page metadata (title, description, 
+viewport settings)
+  	* Had to use manual console commands as workaround
+
+-- 
+
+2. WEB_VIEWPORT_INFO_CREMOTEMCP_CREMOTEMCP
+
+Error: TypeError: (intermediate value)(...).apply is not a function
+
+What Failed:
+
+  	* Same error as web_page_info - internal tool bug
+  	* Could not automatically retrieve viewport width/height, scroll 
+position, device pixel ratio
+
+Impact:
+
+  	* Could not programmatically verify responsive breakpoints
+  	* Could not test zoom levels automatically
+  	* Had to skip automated reflow testing at 320px width
+
+-- 
+
+Didnt complete the some tests :
+
+WHY POOR CONTRAST IS "UNKNOWN" (NOT TESTED)
+
+TECHNICAL LIMITATION:
+
+Color contrast testing requires visual analysis that cannot be reliably 
+automated with JavaScript alone. Here's why:
+
+WHAT CONTRAST TESTING REQUIRES:
+
+	* Computed Background Colors:
+
+  	* Text may be on solid backgrounds, gradients, images, or overlays
+  	* Background color may be inherited from parent elements
+  	* Transparent/semi-transparent layers complicate calculations
+  	* CSS background-image cannot be analyzed for contrast
+
+	* Actual Rendered Colors:
+
+  	* CSS can specify colors that get overridden
+  	* Browser rendering may differ from CSS values
+  	* Hover/focus states change colors dynamically
+  	* Media queries change colors at different breakpoints
+
+	* Visual Context:
+
+  	* Large text (18pt+) has different requirements (3:1) than normal text 
+(4.5:1)
+  	* Bold text affects size thresholds
+  	* Disabled elements have different requirements
+  	* Decorative text may be exempt
+
+WHY AUTOMATED TOOLS FAIL:
+
+// This DOESN'T work reliably:
+const textColor = window.getComputedStyle(element).color;
+const bgColor = window.getComputedStyle(element).backgroundColor;
+// Problem: backgroundColor may be "transparent" or "rgba(0,0,0,0)"
+// Need to traverse parent elements to find actual background
+// Still fails with gradients, images, or complex layouts
+
+WHAT'S ACTUALLY NEEDED:
+
+Chrome DevTools Method (Manual):
+
+  	* Open DevTools (F12)
+  	* Select element with text
+  	* Click color picker next to color property
+  	* DevTools automatically calculates contrast ratio against actual 
+rendered background
+  	* Shows ✅ or ❌ for WCAG AA/AAA compliance
+
+Why This Works:
+
+  	* Chrome's rendering engine knows the actual pixel colors being 
+displayed
+  	* It can analyze the real visual output, not just CSS values
+  	* It handles gradients, images, transparency, and overlays correctly
+
+WHAT I COULD HAVE DONE (BUT DIDN'T):
+
+The cremotemcp tools DO have capabilities I didn't fully utilize:
+
+// Could have used console to check specific elements:
+const element = document.querySelector('nav a');
+const style = window.getComputedStyle(element);
+const textColor = style.color;
+const bgColor = style.backgroundColor;
+
+// But this still requires:
+// 1. Manual identification of which elements to test
+// 2. Manual traversal of parent backgrounds
+// 3. Manual calculation of contrast ratios
+// 4. Manual verification against WCAG thresholds
+
+Why I Marked it "UNKNOWN":
+
+  	* Automated contrast checking would give false positives/negatives
+  	* Professional ADA assessments require manual verification with proper 
+tools
+  	* Better to be honest about limitation than provide inaccurate results
+
+-- 
+
+WHY KEYBOARD ACCESSIBILITY WASN'T FULLY TESTED
+
+WHAT I DIDN'T TEST (MANUAL REQUIRED):
+
+❌ Actual Keyboard Navigation:
+
+  	* Pressing Tab key through all elements
+  	* Verifying focus order matches visual order
+  	* Testing Shift+Tab for reverse navigation
+  	* Verifying no keyboard traps
+  	* Testing Enter/Space on buttons
+  	* Testing arrow keys in dropdowns
+  	* Testing Escape to close modals
+
+❌ Focus Indicator Visibility:
+
+  	* Seeing the actual focus ring/outline
+  	* Measuring focus indicator contrast (3:1 minimum)
+  	* Verifying focus indicator on ALL interactive elements
+  	* Testing custom focus styles (not just browser defaults)
+
+❌ Dropdown Menu Keyboard Access:
+
+  	* Arrow key navigation in menus
+  	* Enter to activate menu items
+  	* Escape to close menus
+  	* Tab to skip through menu
+
+❌ Modal Dialog Keyboard Behavior:
+
+  	* Focus trapped inside modal when open
+  	* Escape key closes modal
+  	* Focus returns to trigger element on close
+
+WHY MANUAL TESTING IS REQUIRED:
+
+Technical Limitation:
+
+What's Needed:
+
+  	* Human tester physically pressing Tab key
+  	* Visual observation of focus indicators
+  	* Testing in real browser with real keyboard
+  	* Screen reader testing (NVDA/JAWS/VoiceOver) to verify announcements
+
+WHY I MARKED IT "LIKELY COMPLIANT":
+
+Evidence of Good Implementation:
+
+  	* ✅ Proper semantic HTML (buttons, links, forms)
+  	* ✅ All elements in accessibility tree
+  	* ✅ Proper ARIA roles and names
+  	* ✅ 34 stylesheets loaded (focus styles likely present)
+  	* ✅ No JavaScript-based fake buttons detected
+
+But Still Requires Verification:
+
+  	* Focus indicators might be too subtle (low contrast)
+  	* Focus order might not match visual order
+  	* Custom components might have keyboard traps
+  	* Dropdown menus might not work with arrow keys

+
+## Prerequisites
+
+### 1. Start Cremote Daemon
+
+```bash
+# Start the daemon on default port 9223
+cremote-daemon
+```
+
+### 2. Start Test HTTP Server
+
+You need a simple HTTP server to serve the test HTML files:
+
+```bash
+# Option 1: Python 3
+cd test/testdata
+python3 -m http.server 8080
+
+# Option 2: Python 2
+cd test/testdata
+python -m SimpleHTTPServer 8080
+
+# Option 3: Node.js (http-server)
+cd test/testdata
+npx http-server -p 8080
+
+# Option 4: Go
+cd test/testdata
+go run -m http.server 8080
+```
+
+The test server should serve files at `http://localhost:8080/`.
+
+### 3. Set Environment Variable
+
+```bash
+export INTEGRATION_TESTS=true
+```
+
+## Running Tests
+
+### Run All Integration Tests
+
+```bash
+cd test
+INTEGRATION_TESTS=true go test -v
+```
+
+### Run Specific Test
+
+```bash
+cd test
+INTEGRATION_TESTS=true go test -v -run TestAccessibilityToolsIntegration
+```
+
+### Run Specific Sub-Test
+
+```bash
+cd test
+INTEGRATION_TESTS=true go test -v -run TestAccessibilityToolsIntegration/AxeCoreIntegration
+```
+
+### Run Benchmarks

+```bash
+cd test
+INTEGRATION_TESTS=true go test -v -bench=. -benchmem
+```
+
+### Run with Coverage
+
+```bash
+cd test
+INTEGRATION_TESTS=true go test -v -cover -coverprofile=coverage.out
+go tool cover -html=coverage.out
+```
+
+## Expected Results
+
+### Accessible Page Tests
+

+
+## Troubleshooting
+
+### Tests Skip with "Skipping integration tests"
+
+**Problem:** Tests are being skipped.
+
+**Solution:** Set the environment variable:
+```bash
+export INTEGRATION_TESTS=true
+```
+
+### "Failed to navigate to test page"
+
+**Problem:** Test HTTP server is not running or not accessible.
+
+**Solution:** 
+1. Start HTTP server on port 8080
+2. Verify server is accessible: `curl http://localhost:8080/test-accessible.html`
+3. Check firewall settings
+
+### "Failed to connect to daemon"
+
+**Problem:** Cremote daemon is not running.
+
+**Solution:**
+```bash
+# Start daemon
+cremote-daemon
+
+# Verify it's running
+ps aux | grep cremote-daemon
+```
+
+### "Failed to inject axe-core"
+
+**Problem:** Network issues or CDN unavailable.
+
+**Solution:**
+1. Check internet connectivity
+2. Try alternative axe-core version
+3. Check if CDN is accessible: `curl https://cdn.jsdelivr.net/npm/axe-core@4.8.0/axe.min.js`
+
+### Tests Timeout
+
+**Problem:** Tests are timing out.
+
+**Solution:**
+1. Increase timeout values in test code
+2. Check system resources (CPU, memory)
+3. Verify Chromium is not hanging
+
+## CI/CD Integration
+
+### GitHub Actions Example
+
+```yaml
+name: Accessibility Integration Tests
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      
+      - name: Set up Go
+        uses: actions/setup-go@v2
+        with:
+          go-version: 1.21
+      
+      - name: Install dependencies
+        run: |
+          sudo apt-get update
+          sudo apt-get install -y chromium-browser
+      
+      - name: Start cremote daemon
+        run: |
+          ./cremote-daemon &
+          sleep 5
+      
+      - name: Start test server
+        run: |
+          cd test/testdata
+          python3 -m http.server 8080 &
+          sleep 2
+      
+      - name: Run integration tests
+        run: |
+          cd test
+          INTEGRATION_TESTS=true go test -v -cover
+      
+      - name: Upload coverage
+        uses: codecov/codecov-action@v2
+        with:
+          files: ./test/coverage.out
+```
+
+## Adding New Tests
+
+### 1. Create Test Function
+
+```go
+func testNewFeature(c *client.Client) func(*testing.T) {
+    return func(t *testing.T) {
+        // Test implementation
+        result, err := c.NewFeature("", params, 10)
+        if err != nil {
+            t.Fatalf("Failed: %v", err)
+        }
+        
+        // Assertions
+        if result == nil {
+            t.Error("Result is nil")
+        }
+    }
+}
+```
+
+### 2. Add to Test Suite
+
+```go
+func TestAccessibilityToolsIntegration(t *testing.T) {
+    // ... existing setup ...
+    
+    t.Run("NewFeature", testNewFeature(c))
+}
+```
+
+### 3. Update Documentation
+
+Update this README with:
+- Tool description
+- Expected results
+- Common issues
+
+## Performance Benchmarks
