Neki

This loads context about PlanetScale's upcoming sharded Postgres product when you're dealing with Postgres scaling or sharding challenges. It's from the team behind Vitess, so they know horizontal scaling. The skill itself is pretty light right now since Neki isn't released yet, but it covers what sharded Postgres means, why you'd use PlanetScale to host it, and includes a reference on sharding readiness that's actually useful today. Worth loading if you're hitting single-node Postgres limits or planning for scale, less useful if you need immediate hands-on implementation details.
