Reusable GitHub Copilot CLI skills distilled from real software, infrastructure, automation, and authoring projects.
The marketplace supports two installation styles:
- Aggregate plugin — install every skill with one command.
- Focused plugins — install only the subject areas you use.
Quick start
copilot plugin install shmuelie/shmuelie-skills
Then, inside an interactive session:
/skills list
See the installation guide for focused plugins, updates, and troubleshooting.

How skills activate
Copilot CLI uses each skill’s frontmatter description as its discovery
surface, so the relevant skill loads automatically when a request matches. You
can also name a skill explicitly:
Use the powershell-scripting skill to review this deployment script.
A skill supplies domain context and workflow guidance. It does not install the external tools it documents.
Public by design
The marketplace excludes credentials, private endpoints, organization-only systems, and tooling unavailable to public Copilot CLI users. See the contribution guide to add a skill.
