Add Skill
SkillDev toolsImport an existing skill from a GitHub repository URL into the current workspace. Use only when the user provides or references a GitHub URL/repo to fetch from (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/. This does not author new skills, to create a new skill from scratch (no source URL), use the skill-creator skill instead.

Workflow
When a user requests to add a skill from a GitHub URL:
- Parse the URL to extract repository owner, name, and skill path
- Fetch the skill using the bundled script:
python3 <this-skill-path>/scripts/fetch_skill.py "<github-url>" "<workspace-path>" - Verify that SKILL.md exists in the destination
- Inform the user the skill is now available
URL Formats Supported
https://github.com/owner/repo/tree/main/path/to/skillhttps://github.com/owner/repo/skill-namegithub.com/owner/repo/skill-nameowner/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
On Windows, use python if python3 is not available and verify with PowerShell, for example: Test-Path C:\path\to\workspace\.agents\skills\codereview\SKILL.md.
Response: "✅ Added codereview to your workspace. The skill is now available."
