Listed from the author's README. GameSkill has not run this end to end yet. Agent support and install steps are as documented by the author.
Install
pip install git+https://github.com/glitchbunny0/unreal-vibe-modding
uvmod install-bridgeSet UVMOD_UE4SS to the game's ue4ss folder in ~/.config/uvmod/config. Skip install-bridge on a UE4SS build with the external REPL.
Commands are copied from the project's README. Check the repository before running anything on your machine.
What you get
- uvmod CLI: run Lua on the game thread, follow UE4SS.log, take screenshots, push mods, hot-swap mod logic
- uvmod mcp: the same functions as MCP tools
- VibeBridge: a small Lua mod so it works with official UE4SS releases
- An agent skill for modding a running game
Good fit
- Iterating on UE4/UE5 game mods without restarts
- Modding a game on a Windows PC from another machine over SSH
Not for
- Games without UE4SS support
- Stable production use: the README marks it early
About this skill
Unreal Vibe Modding closes the loop for modding Unreal games with an agent. You play and describe what feels wrong; the agent runs Lua inside the live game through UE4SS, reads the log, takes a screenshot, writes the mod and hot-swaps it without restarting.
uvmod finds which in-game endpoint answers on its own: UE4SS's external Lua REPL where available, or the bundled VibeBridge mod on any UE4SS build. It works on Windows, Linux with Proton, Steam Deck and WSL, or over SSH to a Windows PC.
