This skill empowers Claude to act as a database performance expert, providing systematic guidance on transforming slow database operations into high-performance queries. It covers critical concepts like interpreting EXPLAIN plans, implementing sophisticated indexing strategies (including composite, partial, and covering indexes), and resolving common anti-patterns such as N+1 queries and inefficient pagination. Whether you are designing a new schema or debugging a production performance bottleneck, this skill provides the implementation patterns needed to reduce database load, minimize costs, and improve application scalability.
