Skills are SKILL.md files (with optional supporting assets) that instruct an AI coding agent how to perform a specialized task. GitHub Copilot in VS Code automatically picks up any .md file under ~/.copilot/skills/.
copilot-skills handles:
- Discovery — searching indexed registries by keyword
- Install — downloading skill files from GitHub via the Contents API
- Manifest — tracking installed skills in
~/.copilot/skills/.manifest.json - Updates — re-fetching skills from their original sources
- Security — sanitizing skill names and file paths to prevent directory traversal
| Variable | Description |
|---|---|
GITHUB_TOKEN |
Optional. Increases GitHub API rate limit from 60 to 5000 req/h |
