Better mods, not more slop.
Made to be played, not just generated.
You design. The agent types.
Tell it what you want. It writes the code, the data files, the file layout. You play the result.
Crash and performance fixes.
The agent launches the game, runs your mod, and monitors the game's logs. When something breaks or slows down, it tells you why and fixes it automatically.
Knows the codebase.
The game's source, its DLCs, and the top community mods are indexed locally. So is a corpus of community modding patterns. The agent works from real symbols instead of guessing.
Art management.
You can repurpose the game's existing textures or bring in your own. The agent wires up sheets, masks, naming, and def references.
One-click publish.
The agent builds the manifest, preview image, tags, and dependency list from your project, then pushes to the Steam Workshop or Modrinth.
Built-in mod manager.
Manages every mod you have installed, not just the ones built in Modmixer. Load order is sorted automatically, dependencies are pulled in, and incompatibilities are flagged before launch.
