+# Deployment URL Detection Pattern for Visual CI Testing
+
+## Overview
+Pattern for automatically detecting deployment URLs (Vercel or custom) in CI/CD pipelines to enable visual regression testing against live deployments instead of localhost.
+
+## Core Pattern
+
+### 1. Multi-Source Detection Strategy
+**Pattern**: Check multiple sources in priority order
+```javascript
+// Priority order:
+1. Manual override (DEPLOYMENT_URL env var)
+2. GitHub secrets (BASE_URL, VISUAL_TEST_URL)
+3. Vercel preview detection (PR comments, deployments API)
+4. Fallback to localhost
+```
+
+**Benefits**:
+- Flexibility for different deployment strategies
+- Graceful fallback when detection fails
+- Support for both automatic and manual configuration
+
+### 2. GitHub Actions Job Separation
+**Pattern**: Separate deployment detection into its own job
+```yaml
+jobs:
+  detect-deployment:
+    runs-on: ubuntu-latest
+    outputs:
+      url: ${{ steps.detect.outputs.url }}
+    steps:
+      # Detection logic here
+  
+  test:
+    needs: [detect-deployment]
+    env:
+      BASE_URL: ${{ needs.detect-deployment.outputs.url }}
+```
+
+**Benefits**:
+- Clean separation of concerns
+- Reusable detection logic
+- Parallel test execution with shared URL
+
+### 3. Vercel Bot Comment Parsing
+**Pattern**: Parse Vercel bot comments for preview URLs
+```javascript
+const vercelComment = comments.find(comment => 
+  comment.user.login === 'vercel[bot]' ||
+  comment.body.includes('vercel.app')
+);
+const urlMatch = vercelComment?.body.match(/https?:\/\/[^\s\)]+\.vercel\.app/);
+```
+
+**Benefits**:
+- Works without Vercel API token
+- Reliable detection method
+- Supports multiple Vercel configurations
+
+### 4. Deployment Readiness Checking
+**Pattern**: Poll deployment URL until ready
+```bash
+MAX_ATTEMPTS=60
+while [ $ATTEMPT -lt $MAX_ATTEMPTS ]; do
+  if curl -s -o /dev/null -w "%{http_code}" "$URL" | grep -q "^[23]"; then
+    echo "Deployment ready!"
+    exit 0
+  fi
+  sleep 5
+done
+```
+
+**Benefits**:
+- Prevents test failures from not-ready deployments
+- Configurable timeout and retry intervals
+- Clear feedback on deployment status
+
+### 5. Configuration Schema
+**Pattern**: Structured deployment configuration
+```json
+{
+  "deployment": {
+    "provider": "vercel|custom|manual",
+    "autoDetect": true,
+    "fallbackUrl": "http://localhost:3000",
+    "waitTimeout": 300000,
+    "retryInterval": 5000
+  },
+  "visualTesting": {
+    "enableOnCI": true,
+    "viewports": ["mobile", "desktop"],
+    "threshold": 0.05
+  }
+}
+```
+
+**Benefits**:
+- Consistent configuration across projects
+- Easy to understand and modify
+- Supports multiple providers
+
+## Implementation Checklist
+
+### Required Files
+- [ ] `/cli/utils/vercel-preview.js` - Detection utility
+- [ ] `/cli/commands/visual-ci.js` - CLI commands
+- [ ] `/templates/config/deployment.json` - Config template
+- [ ] Updated `playwright-web-tests.yml` workflow
+
+### GitHub Secrets
+- [ ] `VERCEL_TOKEN` (optional, for API access)
+- [ ] `DEPLOYMENT_URL` (manual override)
+- [ ] `BASE_URL` (fallback URL)
+
+### CLI Commands
+- [ ] `mac visual:ci-setup` - Interactive configuration
+- [ ] `mac visual:detect-url` - Test detection locally
+- [ ] `mac visual:ci-status` - Show configuration
+
+## Anti-Patterns to Avoid
+
+### ❌ Hardcoding URLs
+- Never hardcode deployment URLs in workflows
+- Always use environment variables or detection
+
+### ❌ Ignoring Deployment Readiness
+- Don't start tests immediately after deployment
+- Always wait for deployment to be accessible
+
+### ❌ Single Detection Method
+- Don't rely on only one detection method
+- Implement fallback strategies
+
+### ❌ Missing Error Handling
+- Always handle detection failures gracefully
+- Provide clear error messages
+
+## Success Metrics
+
+- **Detection Rate**: > 95% for Vercel deployments
+- **Wait Time**: < 60 seconds average
+- **Fallback Usage**: < 5% of runs
+- **Configuration Time**: < 5 minutes setup
+
+## Usage Examples
+
+### Basic Setup
+```bash
+# Configure deployment detection
+mac visual:ci-setup
+
+# Test detection locally
+mac visual:detect-url
+```
+
+### GitHub Actions Integration
+```yaml
+env:
+  BASE_URL: ${{ needs.detect-deployment.outputs.url }}
+  IS_VERCEL_PREVIEW: ${{ needs.detect-deployment.outputs.detected }}
+```
+
+### Manual Override
+```yaml
+env:
+  DEPLOYMENT_URL: https://my-app-preview.vercel.app
+```
+
+## Troubleshooting
+
+### No URL Detected
+1. Check if Vercel bot has commented on PR
+2. Verify GitHub token permissions
+3. Check deployment status in GitHub UI
+4. Use manual override as fallback
+
+### Deployment Not Ready
+1. Increase wait timeout
+2. Check deployment logs
+3. Verify deployment is successful
+4. Test URL manually
+
+### Wrong URL Detected
+1. Check for multiple deployments
+2. Verify regex patterns
+3. Use manual override
+4. Check provider configuration

+## Deployment Detection for Visual CI Testing
+
+### Overview
+The framework now supports automatic deployment URL detection for visual regression testing on CI, allowing tests to run against live preview deployments instead of localhost.
+
+### Supported Providers
+- **Vercel**: Automatic preview URL detection from PR comments
+- **Custom**: Provide your own detection script
+- **Manual**: Specify URL in GitHub secrets
+- **None**: Fallback to localhost
+
+### Configuration
+Projects can configure deployment detection during setup:
+```bash
+mac init  # Prompts for deployment configuration
+mac visual:ci-setup  # Dedicated visual CI configuration
+```
+
+Configuration is stored in `.claude/config/deployment.json`:
+```json
+{
+  "deployment": {
+    "provider": "vercel",
+    "autoDetect": true,
+    "fallbackUrl": "http://localhost:3000",
+    "waitTimeout": 300000
+  },
+  "visualTesting": {
+    "enableOnCI": true,
+    "viewports": ["mobile", "desktop"],
+    "threshold": 0.05
+  }
+}
+```
+
+### GitHub Actions Integration
+The `playwright-web-tests.yml` workflow includes automatic deployment detection:
+1. Checks for manual URL in secrets
+2. Detects Vercel preview from PR comments
+3. Waits for deployment to be ready
+4. Falls back to localhost if needed
+
+### Required Secrets
+- `VERCEL_TOKEN` (optional) - For enhanced Vercel API access
+- `DEPLOYMENT_URL` (optional) - Manual override URL
+- `BASE_URL` (optional) - Fallback URL
+
+### Testing Detection Locally
+```bash
+mac visual:detect-url  # Test detection with current environment
+mac visual:ci-status   # View current configuration
+```
+
