I was quite surprised to find no one had built an LSP for agent skills — one where you can go-to-definition, get skill-completions, refactor (and it renames the folder and the name:), so I went ahead and built one!

(Reminds me of the old Ruby on Rails days where we had to find-and-replace-all in our codebase to refactor things lol.)

Since submitting this on Monday, I've expanded it to provide:

- 1-click install for VS Code, Cursor, Windsurf, VSCodium, Zed

- References & description-on-hover

- Did you mean / safe quick fixes for broken links

- Precise diagnostics for malformed YAML, duplicate keys, invalid types and names, and unbalanced XML

I’d especially love feedback from people maintaining public skill collections: what breaks as those repositories grow?
