Best Practices for AI-Assisted Development

1. Review All Suggestions

Never blindly accept AI-generated code. Always:

• Understand the logic before implementing
• Test thoroughly with edge cases
• Check for security vulnerabilities

2. Use Natural Language Effectively

Write clear, descriptive comments for better suggestions:

// Create a debounced search function that waits 300ms
// and cancels previous requests
const debouncedSearch = // AI will generate the implementation

3. Leverage Context

Keep relevant files open and maintain clear file structures for better AI understanding.
