概要
This skill empowers Claude to act as a specialized database performance engineer, focusing on the identification and resolution of SQL bottlenecks. It provides standardized implementation patterns for running EXPLAIN ANALYZE, creating advanced indexes (composite, partial, and expression-based), and utilizing SQLAlchemy's eager loading features to eliminate N+1 query issues. By integrating performance monitoring decorators and batch loading techniques, it ensures that backend applications remain scalable and responsive even under heavy data loads.
