Boot.dev Hackathon

CoachLint is your AI coding coach. It guides you through errors instead of just solving them for you.

1. Open VS Code
2. Go to Extensions (Ctrl+Shift+X)
3. Search for "CoachLint"
4. Click "Install"

Or install directly: VS Code Marketplace - CoachLint

code --install-extension PranayGhuge.coachlint

Developers are becoming increasingly dependent on quick code fixes and instant code generation. When we use external AI tools, there's no middle ground - the AI just gives you the answer. People copy-paste solutions without understanding the why behind them.

This approach makes us lose the core skill that makes a software engineer valuable: understanding the problem and solving it systematically.

AI is best for breaking down complex errors into very easy and understandable explanations. I believe CoachLint will help developers learn more deeply instead of developing shallow programming skills.

• Error Explanations - Hover over errors for plain English explanations
• Code Quality Review - Get improvement suggestions for your Python code
• Educational Focus - Learn concepts, not just quick fixes
• Secure API Key Storage - Your API key is stored securely in VS Code settings
