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

By slopus/happy (GitHub) · coding · 24,586 stars · scanned at commit ea925c2

Local development guide for the Happy monorepo. How to build, install, test, and run the CLI, server, native iOS and Android apps locally. Use when the user types /dev, asks how to "build", "start dev", "install locally", or "run the ___ package".

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'dev' ] || [ -L ~/.agents/skills/'dev' ]; then echo 'A skill folder named dev already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/slopus/happy' "$d" && git -C "$d" checkout --quiet 'ea925c2c51a5afce9fbed0816ec1e785b50f37d7' -- '.agents/skills/dev' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/dev' ~/.agents/skills/'dev' && 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/'dev' ~/.claude/skills/'dev' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
