How AI Coding Tools Work

AI coding assistants use large language models trained on millions of code repositories. They analyze your code context — including open files, imports, and comments — to suggest relevant completions, fixes, and new code.

Types of AI coding assistance:
• Inline completion — Suggests code as you type
• Chat interface — Ask questions about your codebase
• Code generation — Generate code from natural language descriptions
• Bug detection — Identify potential issues before runtime

AI Coding Best Practices

1. Review all AI-generated code — Never trust it blindly
2. Provide context — Good comments and naming help AI understand your intent
3. Start small — Use AI for functions, not entire applications
4. Learn to prompt — Clear, specific instructions get better results
5. Keep learning — AI augments your skills but doesn't replace understanding
