✅ Do's & Don'ts
✅ DO's
- Provide clear context (e.g., "in mobile app" or "for GDPR compliance")
- Ask "why" questions to understand trade-offs
- Use the 5-step deep dive formula for thorough analysis
- Cross-reference findings with multiple commands
- Share results and data with your team
- Update your knowledge as codebase evolves
- Export findings for documentation
❌ DON'Ts
- Ask vague questions without context
- Assume results without verification
- Use old findings for new decisions
- Skip verification with engineering teams
- Over-rely on estimates without buffer
- Ignore security audit recommendations
- Make decisions without understanding trade-offs

�� Troubleshooting Common Issues
Q: "Command not found" error
Make sure you've installed Copilot CLI globally: npm install -g @github/copilot-cli
Q: Authentication fails
Run copilot auth logout then copilot auth login again. Ensure your GitHub account has access to the target repository.
Q: Results seem inaccurate
Provide more context with the --context flag. Example: copilot explain 'auth' --context 'mobile security'
Q: How do I update to latest version?
Run npm update -g @github/copilot-cli
Q: Can I use Copilot CLI offline?
No, Copilot CLI requires internet connection to analyze your codebase with GitHub's AI models.
