// Sync user-level Claude skills from the bundled SKILL.md files shipped in this

// Code plugin marketplace — both come from the repo at release time, so the two
// install paths (npm + plugin marketplace) stay in lockstep.

// rotted across releases and produced the stale "Using npx — always latest"
// output that blocked multiple version bumps. Source-of-truth is now disk.
