Universal Modder is a skill pack and toolkit that lets Claude Code carry a modding idea for a PC game you own through to a version that runs in the actual game, recorded on video. It scans which games are installed and their engine, mod loaders and anti-cheat, picks the cheapest route, sets up a safe test copy and builds one small working slice first. Art and sound can be generated through the fal MCP, changes are checked in the running game, and it can package the mod and record a showcase clip. The author's examples include a Terraria mod, an extra civilization for the second Age of Empires and a Minecraft-in-GTA V mashup.
