upskill

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

Install

• Standalone

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

• GitHub CLI extension

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

Usage

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

Overwrite existing skills:

upskill anthropics/skills --all --force

Subcommands

upskill list                        # Show local skills
upskill info pdf                    # Show skill details
upskill read pdf                    # Print SKILL.md content
upskill search "pdf converter"      # Search registries

Install sources

Besides GitHub repositories, skills can be installed from ClawHub and Tessl registries:

upskill clawhub:tavily-search                # Install from ClawHub by slug
upskill https://clawhub.ai/user/my-skill     # Install from ClawHub by URL
upskill tessl:postgres-pro                   # Install from Tessl registry

The owner/repo@branch inline syntax is also supported (the -b flag takes precedence if both are specified):

upskill anthropics/skills@main --list

Filter by subfolder

Use -p or --path to restrict skill discovery to a subfolder within the repository. This is useful for repos that organize skills in nested directories:

upskill adobe/skills --path plugins/aem/edge-delivery-services --list
upskill adobe/skills --path plugins/aem/edge-delivery-services --all
