add-skill

name	add-skill
description	Add an external skill from a GitHub repository to the current workspace. Use when users want to import, install, or add a skill from a GitHub URL (e.g., `/add-skill https://github.com/OpenHands/extensions/tree/main/skills/codereview` or "add the codereview skill from https://github.com/OpenHands/extensions/"). Handles fetching the skill files and placing them in .agents/skills/.

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:

   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/extensions/tree/main/skills/codereview

# Run the fetch script
python3 scripts/fetch_skill.py "https://github.com/OpenHands/extensions/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."

Notes

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