The Database Optimizer is a specialized Claude Code skill designed to identify and resolve performance bottlenecks in database systems like PostgreSQL, MySQL, and SQLite. It operates with a 'measurement-first' philosophy, ensuring that any changes to queries, indexes, or schemas are backed by execution plan analysis and data-driven insights. By prioritizing data integrity and operational stability, this skill helps developers eliminate slow queries, reduce lock contention, and implement robust scalability patterns without risking production downtime or data loss.
