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?
