How does this skill help with database security?

It enforces the use of parameterized queries and prepared statements to ensure that user-provided data cannot lead to SQL injection attacks.

When should I use the Backend Queries skill?

Use it whenever you are creating or modifying files in your repository, query, or data access folders to ensure high-quality database interactions.

Does it support specific ORMs like TypeORM or Sequelize?

While it provides general database best practices, it is designed to work across various ORMs and query builders by applying universal optimization and security patterns.

Can it fix performance issues like N+1 queries?

Yes, the skill specifically guides Claude to identify N+1 patterns and implement eager loading or optimized joins to reduce database round-trips.
