Skill grades on GitHub, where you find skills

Open a Claude skill on GitHub and see what Skills Directory knows about it: its security grade, what the scan found, and the command to install it. No switching tabs.

What it sends us

Only on GitHub pages that show a SKILL.md or a skills folder, it sends the repository name and folder path to look the skill up. It doesn't run on other sites, doesn't send your browsing history, and has no analytics. To show Pro buttons, it checks whether Pro is on in this browser. Details are in the privacy policy.
