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.

npx skill-studio diagnoseQuestions.
Read the docsWhich 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?
Not yet. Park moves the skill's copy out of the folder that agents read, so a skill in the shared folder goes off for every agent that reads it. Turning it off for one agent only is coming.
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.
