Install Agent Skills from GitHub repositories.

Note: This tool implements the agentskills.io specification. Your AI agent (Claude Code, Cursor, VS Code, etc.) likely already supports this spec natively and can discover skills automatically. This tool is primarily useful for:

• Installing skills from private repositories
• Batch installing multiple skills
• Managing skills across projects

• Standalone

  • macOS/Linux: curl -fsSL https://raw.githubusercontent.com/trieloff/gh-upskill/main/install.sh | bash
  • Custom prefix: curl -fsSL https://raw.githubusercontent.com/trieloff/gh-upskill/main/install.sh | bash -s -- --prefix ~/.local

• GitHub CLI extension

  • gh extension install trieloff/gh-upskill
  • Then run via gh upskill ... (or use upskill directly)

Skills are discovered by scanning for **/SKILL.md files per the agentskills.io spec.

List available skills:

upskill anthropics/skills --list

Install specific skills:

upskill anthropics/skills --skill pdf --skill xlsx

Install all skills:

upskill anthropics/skills --all

Use the -g or --global flag to install skills to ~/.skills instead of the project's .skills directory:

upskill -g anthropics/skills --skill pdf --skill xlsx

When installing globally:

• Skills are installed to ~/.skills
• .agents/discover-skills and AGENTS.md are not modified (since these are project-specific)

Use --dest-path to install skills to a custom location:

upskill anthropics/skills --skill pdf --dest-path .claude/skills

This is useful for compatibility with tools that expect skills in different locations (e.g., .claude/skills).

1. Clones the source repository to a temp directory
2. Scans for all **/SKILL.md files (per agentskills.io spec)
3. Copies selected skill directories to .skills/ (or custom destination)
4. Creates .agents/discover-skills helper script
5. Updates AGENTS.md with skills section (if source has one)

After installing, list available skills in your project:

./.agents/discover-skills

This scans both project skills (.skills/) and personal skills (~/.skills/), plus legacy .claude/skills locations for backwards compatibility.

• Lint: make lint (shellcheck)
• Test: make test (network required for gh repo clone)
• CI runs lint + tests on pushes/PRs to main.
