AI Skills for software development
Usable Skills and open-source skill projects, in one list.
A usable Skill is reviewed and pinned to one version. A listing points to a project on GitHub. Choose a task guide
Two kinds of entry, side by side: reviewed Skills, pinned to one version with the permissions they ask for, and open-source projects on GitHub that give an AI coding assistant a repeatable way to review a change, write tests or trace a bug. Each links to its source and licence; read the author’s instructions before you add one to your setup.
