# Universal Modder: Claude Code plugin that builds mods for PC games

Universal Modder is a Claude Code plugin (also usable with Codex, Gemini CLI and Cursor) that gives agents skills to mod almost any PC game: it detects the game and engine, reads the game code to build the mod, generates art, 3D models and sound via fal, tests it in the running game, records a video, and records learnings for future runs. Install with /plugin marketplace add rehan-remade/universal-modder then /plugin install universal-modder@universal-modder; a fal API key is required for asset generation.

## Description

Point your AI coding agent at a PC game you own, and it builds a mod for it. 8.8K stars.

Universal Modder gives Claude Code, Codex, Gemini CLI, Cursor and others the skills to mod almost any PC game:
→ finds the game and works out its engine
→ reads the real game code and builds the mod
→ makes the art, 3D models and sound with fal
→ tests it in the running game
→ cuts a video of the result
→ writes down what it learned so the next agent starts smarter

Install in Claude Code:
/plugin marketplace add rehan-remade/universal-modder
/plugin install universal-modder@universal-modder

Any other agent:
npx skills add https://t.co/LVa2sWb511

Generating art and sound needs a fal API key. Only mod games you own, and keep mods out of online multiplayer.
