Import 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/").

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'add-skill' ] || [ -L ~/.agents/skills/'add-skill' ]; then echo 'A skill folder named add-skill already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/OpenHands/extensions' "$d" && git -C "$d" checkout --quiet 'b98ac0671a51cc91bab3609bf4d334c7c832dd98' -- 'skills/add-skill' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/add-skill' ~/.agents/skills/'add-skill' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'add-skill' ~/.claude/skills/'add-skill' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
