if [ -e ~/.agents/skills/'caveman-setup' ] || [ -L ~/.agents/skills/'caveman-setup' ]; then echo 'A skill folder named caveman-setup already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/JuliusBrussee/caveman' "$d" && git -C "$d" checkout --quiet '3dc497a7f858c774d6e15b25e8c6120ef3a0eda8' -- 'skills/caveman-setup' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/caveman-setup' ~/.agents/skills/'caveman-setup' && 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/'caveman-setup' ~/.claude/skills/'caveman-setup' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
