SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you eliminate slow, insecure database queries (SQL injection, N+1 problems) that degrade application performance and security, by guiding you to write optimized and safe data access logic.

Core Features & Use Cases

Secure Query Construction: Write database queries using parameterized statements to prevent SQL injection.
Performance Optimization: Implement eager loading and strategic indexing to avoid N+1 query problems and improve data fetching speed.
Use Case: Refactor a Django ORM query to eager load related Author objects for a list of Book objects, preventing N+1 query issues and speeding up page loads.

Quick Start

Using the Backend Queries skill, write a SQLModel query to fetch all active users, eagerly loading their associated 'profile' data to avoid N+1 queries.
