Technical Validation

Using Helper Script:

The skill includes a Python helper script for URL validation:

bash
# Validate URLs from a file

• API endpoints

Examples

Example 1: URL Validation

Input: Validate URLs in blog post

Output:

markdown
## URL Analysis: Blog Post

### Technical Validation

**1. https://example.com/article**
- **Status**: 200 OK
- **Response Time**: 320ms
- **SSL**: Valid
- **Redirects**: None

**2. https://old-site.com/page**
- **Status**: 301 → https://new-site.com/page
- **Issue**: Redirect chain (should update link)
- **Fix**: Update to final destination

**3. https://broken-link.com**
- **Status**: 404 Not Found
- **Issue**: Broken link
- **Fix**: Remove or find alternative

### Contextual Analysis

**4. https://example.com/article**
- **Link Text**: "Learn more about React"
- **Destination**: React documentation
- **Relevance**: High ✓
- **Status**: Appropriate

**5. https://example.com/homepage**
- **Link Text**: "Advanced React patterns"
- **Destination**: Homepage (not specific article)
- **Relevance**: Low ✗
- **Issue**: Link text doesn't match destination
- **Fix**: Link to specific article or update link text

Best Practices

URL Validation

1. Check Status: Verify all links return 200 or appropriate redirect
2. Update Redirects: Use final destination, not redirect chains
3. Context Matters: Ensure links match their context
4. Security: Prefer HTTPS, check SSL validity
5. Relevance: Verify linked content matches expectations
