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/'testing-codegen' ] || [ -L ~/.agents/skills/'testing-codegen' ]; then echo 'A skill folder named testing-codegen already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/modem-dev/ossrules' "$d" && git -C "$d" checkout --quiet '9625409b6c20077e1d92909e15e800608a85a776' -- 'public/files/biomejs/.claude/skills/testing-codegen' && mkdir -p ~/.agents/skills && cp -R "$d"/'public/files/biomejs/.claude/skills/testing-codegen' ~/.agents/skills/'testing-codegen' && 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/'testing-codegen' ~/.claude/skills/'testing-codegen' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
