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

if [ -e ~/.agents/skills/'ultrathink-detective' ] || [ -L ~/.agents/skills/'ultrathink-detective' ]; then echo 'A skill folder named ultrathink-detective already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadAppGang/claude-code' "$d" && git -C "$d" checkout --quiet '6097ad4643f23b7645a9c99c329887b623b32e57' -- 'plugins/code-analysis/skills/ultrathink-detective' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/code-analysis/skills/ultrathink-detective' ~/.agents/skills/'ultrathink-detective' && 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/'ultrathink-detective' ~/.claude/skills/'ultrathink-detective' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
