Best Practices for AI-Assisted Development

1. Review Everything

Don't blindly accept:

  • Security implications
  • Performance issues
  • Edge cases
  • Best practices

Always verify:

  • Logic correctness
  • Security vulnerabilities
  • Code quality
  • Test coverage

2. Provide Context

Better prompts:

  • Include framework versions
  • Mention tech stack
  • Describe constraints
  • Share relevant code

Example: ❌ "Fix this error" ✅ "Fix this TypeScript error in Next.js 14 App Router with Supabase client"

3. Iterate

Process:

  1. Initial AI generation
  2. Review output
  3. Ask for improvements
  4. Refine further
  5. Test thoroughly

4. Learn from AI

Don't just copy-paste:

  • Ask AI to explain
  • Understand the approach
  • Learn new patterns
  • Build knowledge

5. Use Multiple Tools

Combine strengths:

  • Cursor for coding
  • ChatGPT for architecture
  • v0 for UI
  • Claude for complex logic

Common Pitfalls to Avoid

1. Over-Reliance

Problem: Not understanding the code Solution: Always learn what AI writes

2. Security Blind Spots

Problem: AI might suggest insecure code Solution: Review security-critical code carefully

3. Outdated Information

Problem: AI training data has cutoff Solution: Verify with current documentation

4. Copy-Paste Without Testing

Problem: Bugs in production Solution: Test everything AI generates

5. Ignoring Context

Problem: AI doesn't know your full project Solution: Provide relevant context
