Add Skill

Import skills from GitHub repositories into the current workspace.

Workflow

When a user requests to add a skill from a GitHub URL:
  1. Parse the URL to extract repository owner, name, and skill path
  2. Fetch the skill using the bundled script:
    bash
    python3 <this-skill-path>/scripts/fetch_skill.py "<github-url>" "<workspace-path>"
  3. Verify that SKILL.md exists in the destination
  4. Inform the user the skill is now available

URL Formats Supported

  • https://github.com/owner/repo/tree/main/path/to/skill
  • https://github.com/owner/repo/skill-name
  • github.com/owner/repo/skill-name
  • owner/repo/skill-name
    (shorthand)

Example

User:
/add-skill https://github.com/OpenHands/skills/tree/main/skills/codereview
bash
# Run the fetch script
python3 scripts/fetch_skill.py "https://github.com/OpenHands/skills/tree/main/skills/codereview" "/path/to/workspace"

# Verify installation
ls /path/to/workspace/.agents/skills/codereview/SKILL.md
Response: "✅ Added
codereview
to your workspace. The skill is now available."

    directory if it doesn't exist
  • Uses
    GITHUB_TOKEN
    for authentication (required for private repos)
  • Warns before overwriting existing skills with the same name
