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

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.
