Unreal Engine — AI Game Dev runbook

This skill teaches your AI coding assistant (Claude Code, Codex, Cursor or Gemini CLI) to drive Unreal Engine fully automatically through the unreal-mcp-cli npm package. The goal: take the user from nothing to a running Unreal Editor that is connected to ai-game.dev so the AI can build the game for them.

Every command runs via npx so nothing needs to be installed globally:

npx -y unreal-mcp-cli@latest <command> [args]     # <command> --help shows every flag

Path syntax differs by command: create-project, install-plugin, close, open, and install-extension take the project path as a positional argument; wait-for-ready, status, setup-mcp, setup-skills, and exec take it as -p <path>.
