Combining Tools

Many developers use multiple tools together:

  1. Claude for planning and complex reasoning
  2. Copilot/Cursor for writing code
  3. ChatGPT for quick questions and learning

Best Practices Across All Tools

General Tips

  1. Verify generated code - Always review before committing
  2. Understand what you commit - Don't ship code you don't understand
  3. Test thoroughly - AI can generate plausible but incorrect code
  4. Consider security - Review for vulnerabilities
  5. Keep learning - Use AI to accelerate learning, not replace it
