Agent skills, tested before you install them.

There are millions of SKILL.md files out there and no way to tell the good ones from the risky ones. We run each skill on a standard task, with and without it loaded, scan it for security red lines, and publish the score — evidence included.

Download counts and GitHub stars are shown as background and never count toward the score. Read the full methodology →
