mod-any-game
Agent skill from
Mod a PC game the user owns, taking an idea to working in the real game and recorded. It covers new items, weapons, enemies, bosses, units, civilizations, mechanics, art, sound, VR and cross-game mashups. Use when the user wants to mod, extend, hack on, reverse engineer or mash up a game ("add a nuke to Terraria", "make a new civ for Age of Empires", "put Minecraft inside X", "can I mod this game?"). It covers recon (engine, loaders, anti-cheat), choosing the route, a safe lab, a first vertical slice, fal-generated assets, in-game verification and a showcase clip.

The Claude Code plugin and a clone opened in Claude Code put it18on PATH; other agents' plugin installs don't. If `command -v um` finds nothing, use `bin/um` in a clone, or19install it once: `uv tool install git+https://github.com/rehan-remade/universal-modder` (or `pipx install ...`).20Every group has `--help` with examples.2122| Need | Command |23|---|---|24| What games are installed, what engine, what anti-cheat, where saves live | `um scan --list`, `um scan "<game>"` |25| Sprites, textures, PBR, 3D models, rigs, SFX, music, voice, video (fal) | `um fal <recipe>`, or the fal MCP (`search_models`, `run_model`) |26| Cut out / fit / pixelate / pack sprites; 3D model → sprite frames | `um sprite ...`, `um render3d ...` |27…
