Backend Queries

This Skill provides Claude Code with specific guidance on how to adhere to coding standards as they relate to how it should handle backend queries.

When to use this skill

• When writing database queries in controllers, service classes, repositories, or model methods
• When using query builder methods (where, select, join, orderBy, etc.)
• When implementing eager loading to prevent N+1 query problems (with, load, etc.)
• When optimizing queries by selecting only needed columns instead of using SELECT *
• When implementing filtering, sorting, or pagination logic in queries
• When writing complex queries with joins, subqueries, or aggregations
• When wrapping multiple related database operations in transactions
• When implementing query timeouts or performance optimization
• When adding database indexes to improve query performance
• When implementing query result caching strategies
• When using raw queries or complex SQL (ensuring parameterization for security)
• When debugging slow queries or performance issues
