Database Skills is a collection of instructions for AI coding assistants that cover database design, queries, troubleshooting, and operations. It is for developers working with MySQL, PostgreSQL, PlanetScale's Neki and Vitess systems, including schema changes, performance issues, replication, and sharding. The catalogue entries are the individual skills for those database technologies.
Plan and review MySQL/InnoDB schema, indexing, query tuning, transactions, and operations. Use when creating or modifying MySQL tables, indexes, or queries; diagnosing slow/locking behavior; planning migrations; or troubleshooting replication and connection issues. Load when using a MySQL database.
Guidance for Neki, PlanetScale's distributed (sharded) Postgres. Load when working with a Neki database — connecting, data topology and shard keys, query routing and fanout, cross-shard transactions, schema changes, resharding and migration, NK013 errors — or when scaling and sharding Postgres.
Vitess best practices, query optimization, and connection troubleshooting for PlanetScale Vitess databases. Load when working with Vitess databases, sharding, VSchema configuration, keyspace management, or MySQL scaling issues.
