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

if [ -e ~/.agents/skills/'react-doctor' ] || [ -L ~/.agents/skills/'react-doctor' ]; then echo 'A skill folder named react-doctor already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/yanacuti1121/Yana-AI' "$d" && git -C "$d" checkout --quiet '54d4aa9fa3241319f4d37212bd23826658bf6bed' -- '.claude/skills/react-doctor' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/react-doctor' ~/.agents/skills/'react-doctor' && 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/'react-doctor' ~/.claude/skills/'react-doctor' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
