Agent Skill Sync is a small extension that does one thing well: it pulls skills and rules from a GitHub repo (or a custom registry) and drops them where Cursor (and friends) actually look—.cursor/rules and .cursor/skills. No copy-paste. No “did everyone update the repo?” .
You can grab it on the Open VSX Registry: KeskaLabsAB / agent-skill-sync.
What it does (without the brochure voice)
You connect a source—usually owner/repo on GitHub. The Skill Manager opens in the sidebar: Manage for what’s on in this workspace, Browse if you want to poke around the tree like a civilized person. There’s also catalog search when you’d rather type “api docs” than click five folders.
Content-wise we support the boring-but-useful stuff:
Single-file rules (.mdc, .md, etc.) → synced as Cursor-style rules.
Skill packages—folders with a SKILL.md in the agentskills.io shape → whole directory lands under .cursor/skills/<name>/ when you flip it on.
So your “skills repo” can be a real repo: versioned, reviewed, boring in a good way.
Why we bothered publishing it
Internally we were already curating skills in git—security checklists, PR templates, little opinionated prompts that make agents less chaotic. The missing piece was getting that into the editor without ceremony. We got tired of documenting the manual steps for every new machine and every new teammate.
Publishing it was basically: if we need this, someone else might too—and Open VSX is a fine home for tooling that isn’t married to a single storefront. Same extension, same idea: your skills live in source control; the editor just syncs what you opted into.
How to use it (the short path)
Install from Open VSX: agent-skill-sync.
Open the Skills view (or run the command palette entry for managing skills—your muscle memory may vary).
Sign in to GitHub if the repo is private; we use the normal provider flow, nothing exotic.
Point it at your repo (owner/repo) or switch to registry mode if that’s your setup.
On Manage, toggle what you want. Sync runs in the background or when you hit refresh—either way, files show up under .cursor/rules and .cursor/skills in the workspace you’re in.
Keyboard shortcut people: Ctrl+Alt+S (Windows/Linux) or Cmd+Alt+S (macOS) focuses the sidebar, unless you’ve remapped it to something weirder. We don’t judge.
Settings are the usual skillSync.* keys—source mode, repo string, registry URL, categories, opted-in list. If you live in JSON settings, you already know where to click.
Fine print, but make it fashion
GitHub traffic uses your session. We’re not shipping analytics in the extension to tell you how often you toggled “API documentation.” Skills land in your workspace paths; nothing magic happens in our cloud because there isn’t one for this.
If something breaks, open an issue on github.com/keska-labs/enterprise-skills. If it doesn’t break, enjoy the part where your agent actually reads the same files as the rest of the team.
