This editor is completely AI-built. Every line of code, every test, the build scripts, this manual and all graphics – the editor’s logo and icon – were created by Claude, Anthropic’s AI. I didn’t write any of the code by hand. (The one exception: my company’s LT Design logo, which I made myself, without AI.) I decided what to build, tried it on my own mods and reported what didn’t work; Claude wrote and changed everything. Hence the name: it’s AI “slop” – tested and useful, but keep that in mind. More about how it was made.

What it does
The editor opens your mod on top of the game and any base mods and shows the result the game will see: every entity, string, brush, texture and mesh, and where each comes from. You can browse it, change it, check it for problems and preview it – and the editor only ever writes into your own mod, in the game’s own file formats.
| Getting started | Install, open a mod, find your way around: tabs, history, search. |
| Dashboard | Counts, races, layers and the problems of a mod, with one-click fixes. |
| Entities | Lists and forms for ships, abilities, buffs, research …: editing, references, strings, duplicating, renaming, deleting. |
| Research trees | A race’s research screen as the game draws it: move subjects, link prerequisites, create new ones. |
| Brushes | Button and icon images: change them, create new ones, with their state variants and texture atlases. |
| Textures and meshes | Image viewer and a 3D view with the game’s own shaders, particles, a cel-shading style for icons, pictures for brushes, and scaling. |
| Problems and game log | What’s wrong with a mod, what the game’s AI is missing, and what the game itself reported. |
| Reference | Files the editor writes, keyboard shortcuts, command line, building from source. |
