YOUR TASK:
Create an EXCELLENT SKILL.md file that will help Claude use this documentation effectively.

Requirements:
1. **Clear "When to Use This Skill" section**
   - Be SPECIFIC about trigger conditions
   - List concrete use cases

2. **Excellent Quick Reference section**
   - Extract 5-10 of the BEST, most practical code examples from the reference docs
   - Choose SHORT, clear examples (5-20 lines max)
   - Include both simple and intermediate examples
   - Use proper language tags (cpp, python, javascript, json, etc.)
   - Add clear descriptions for each example

3. **Detailed Reference Files description**
   - Explain what's in each reference file
   - Help users navigate the documentation

4. **Practical "Working with This Skill" section**
   - Clear guidance for beginners, intermediate, and advanced users
   - Navigation tips

5. **Key Concepts section** (if applicable)
   - Explain core concepts
   - Define important terminology

IMPORTANT:
- Extract REAL examples from the reference docs above
- Prioritize SHORT, clear examples
- Make it actionable and practical
- Keep the frontmatter (---\\nname: ...\\n---) intact
- Use proper markdown formatting

SAVE THE RESULT:
Save the complete enhanced SKILL.md to: {self.skill_md_path.absolute()}

First, backup the original to: {self.skill_md_path.with_suffix('.md.backup').absolute()}
