Skills source and sync
Skills are sourced from the planetscale/database-skills repository. A copy lives in skills/ for install compatibility, and a Git submodule at database-skills/ tracks the upstream.
GitHub Actions runs .github/workflows/update-skills.yml weekly (with manual workflow_dispatch support). When the upstream has new commits, the workflow copies the latest skills into skills/ and opens a PR.

npx skills add https://github.com/planetscale/vscode-agent-plugin --skill <name>Pick the skill name from the Skills tab — each entry there installs independently.
