What is Universal Modder?

An open-source toolkit that gives your AI coding agent modding skills, local tools and a shared knowledge base for PC games you own.

What it brings to your agent

• Game research: look for prior field notes and identify a possible modding route.
• Local tooling: inspect files, manage backups, build a working slice and package your work.
• Asset workflows: work with sprites, 3D and audio; optional cloud services have separate costs.
• Recorded lessons: contribute findings with versions, verification and unresolved problems.

What you need before starting

A game you own, a coding agent, access to your local game files and a loader or route that fits your exact game version. The README lists Python 3.10+ and ffmpeg; uv is recommended. Blender is needed for 3D-to-sprite rendering. Windows game automation runs on Windows or through WSL.

The upstream README documents integrations for Claude Code, Codex, Gemini CLI, VS Code / Copilot, Cursor and OpenCode. Integration support does not certify compatibility with every PC game.

The practical workflow

1. Identify your game version and read a relevant field note.
2. Back up saves and describe one small change.
3. Build with placeholder assets and verify the result in your actual game.
4. Add assets, repeat the checks and keep a recovery record.

What costs money?

The toolkit is MIT-licensed. Agent subscriptions or model usage, cloud asset generation and the game itself may cost money. ModLab has not measured a full run, so we do not publish a per-mod price estimate.
