Vitess

This is PlanetScale's official skill for working with Vitess, the MySQL-compatible sharding system that powers their managed database service. Load it when you're dealing with VSchema configuration, query routing across shards, or figuring out why your connection pooling isn't scaling like you expected. It covers the sharp edges: cross-shard joins that'll murder performance, foreign key limitations, and why you need sequences or UUIDs for IDs on sharded tables. The references go deep on VReplication, online DDL strategies, and architectural components like VTGate and VTTablet. If you're building anything on PlanetScale or self-hosting Vitess, this gives Claude the context to actually help with sharding decisions instead of generic MySQL advice.
