LABSCO SUMMARY
mysql covers InnoDB schema design, indexing, query tuning, transactions, and diagnosing slow or locking behavior. postgres covers query optimization, connection troubleshooting, and general performance work. vitess covers query optimization and connection troubleshooting specifically for PlanetScale's sharded-MySQL setup, including VSchema and keyspace management. neki is PlanetScale's own sharded-Postgres product, and its own dependency note in our data says plainly that Neki "is not yet a released product, but will be available soon" — so that skill is describing something you cannot use yet, not something installed and ready.
The four skills are not new content written for this repository: the README states they're sourced from the separate planetscale/database-skills repository, mirrored into this one's skills/ folder "for install compatibility," with a Git submodule tracking the upstream and a weekly GitHub Action opening a PR whenever it changes. What this repository actually adds is the bundled MCP server and the VS Code/Copilot install path, not new skill material.
READ THE FULL ANALYSIS
This targets GitHub Copilot, not Claude. Installation is copilot plugin install planetscale/vscode-agent-plugin from the Copilot CLI, or registering this repo's path under VS Code's chat.plugins.paths setting with chat.plugins.enabled turned on — no Claude Code or claude.ai install path is described anywhere in the README. Someone who wants these four database skills inside Claude should look at the upstream planetscale/database-skills repository directly rather than this wrapper.
The bundled MCP server needs your own PlanetScale login; the four skills by themselves do not. All four carry no dependency beyond installing the plugin, but the MCP server that ships alongside them authenticates against your actual PlanetScale organizations, databases, branches, and Insights data — so the skills' guidance is free to read, and querying your real schema is not. The plugin also isn't yet listed on GitHub's own copilot-plugins or awesome-copilot marketplaces; as of this README it has only been submitted, so installing directly from the repository is the only path today.

SETUP
Showing all 4 skills
mysql
Plans and reviews changes to a MySQL database — new tables, indexes, or queries — and asks for real evidence and a rollback plan before anything reaches production.
neki
An overview of Neki, PlanetScale's sharded Postgres product, with guidance for shaping a Postgres schema now so it can shard cleanly once Neki ships.
postgres
A second opinion on a Postgres database — whether the schema and the indexes are right, and what is behind the slow queries, the bloat, or the connections running out.
vitess
Splitting one MySQL database across many machines changes what ordinary SQL can do; this covers how to design for that split and which familiar features stop working.
No skill in this package matches that.
