Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Install

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

if [ -e ~/.agents/skills/'create-builtin-tool' ] || [ -L ~/.agents/skills/'create-builtin-tool' ]; then echo 'A skill folder named create-builtin-tool already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/fritzprix/libr-agent' "$d" && git -C "$d" checkout --quiet '0679557c88a47a5b14b020b9785e0de95e0a1f94' -- '.agents/skills/create-builtin-tool' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/create-builtin-tool' ~/.agents/skills/'create-builtin-tool' && 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/'create-builtin-tool' ~/.claude/skills/'create-builtin-tool' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
