Your first mod with Universal Modder
Understand the workflow, choose a small first change, and know what a working result looks like.
Start with one small change
Universal Modder gives an AI coding agent skills, tools and a shared knowledge base for researching and modifying PC games. You still need a compatible environment, a game you own and a way to verify the result.
Choose a visible, reversible change: a single item, a simple texture or a small balance adjustment. A cross-game mashup introduces far more dependencies and is a poor first project.
Identify your exact environment
Record your operating system, game storefront, game build, agent version and existing mod loader. Ask the agent to inspect the game and search prior field notes before changing files.
A playbook for an engine is a possible route, not proof that your particular game version works.
Make a backup and a working slice
Back up saves before edits. Use a separate mod project and the established loader for your game when available. Ask the agent to show which files it plans to change and how to undo the change.
Build the smallest version first. Verify that it loads in the real game before generating extra art, sound or mechanics.
Define success before you run it
Write down a reproducible test: load the same save, obtain the new item, use it, restart the game and confirm it still works. Keep the game version, loader version and relevant logs with the result.
A successful compilation or a screenshot of generated code does not prove that the mod works in the game. Use the brief builder to prepare these requirements.
