AI Guide

What AI helps with

  • ✓ Writing CRUD route templates fast
  • ✓ Generating SQL queries from plain English
  • ✓ Debugging error messages
  • ✓ Writing API documentation
  • ✓ Suggesting database schema improvements

What AI cannot replace

  • ✗ Security-sensitive auth logic, always review yourself
  • ✗ Business logic requiring domain knowledge
  • ✗ Replacing testing

Recommended Tools

GitHub Copilot / Cursor

In-editor code generation

Claude

Architecture planning, code review, API docs

Postman AI

Auto-generate API test collections

Sample Prompts

Write a FastAPI endpoint that accepts a user registration form (email, password, full name), hashes the password with bcrypt, saves to PostgreSQL using SQLAlchemy, and returns a JWT token. Include proper error handling for duplicate emails.
I have this SQL query running slowly on 2 million rows: [paste]. Suggest indexes and optimizations.
Explain this PostgreSQL error and suggest a fix: [paste error]
