Tidy up your
agent skills.

Skills pile up across your agents and projects. Skill Studio shows which are broken, which are duplicates and which your agents never use, so you can clear them out with undo.

Skills pile up.

Some point to folders that no longer exist.
Some are copies of each other that have drifted apart.
Most never run, yet each one adds its name and description to every session.

How it works.

Your project has its own copy of a skill. See it next to the global copy, see which agents read each one, and compare what changed.

Use it your way.

Questions.

Read the docs

Which agents does it work with?

Claude Code, Codex, OpenCode, pi, Cursor and Grok Build, plus the shared .agents folder. It finds skills globally and in the projects you work in.

Does parking delete a skill?

No. The skill moves to a parked folder, and you can unpark it at any time.

Can I undo a change?

Yes. Changes go into a history you can undo. Skill Studio keeps a backup of each skill it removes. To undo a park, unpark the skill.

Does it work with npx skills?

Yes. It installs, updates and removes skills through npx skills and reads the lock file. It also works with dotagents.

Can I turn a skill off for one agent only?

Yes, in Claude Code, Codex and OpenCode.

Does it send my data anywhere?

No account is needed and it runs on your Mac. It goes online only to browse and install skills, check for updates and send crash reports. Crash reports are anonymous and you can turn them off. They never include skill names, files or paths.

Is it free?

Yes. It is open source under the MIT license.

Clear out your skills.

Keep the ones your agents use and park the rest.
