About this project

Sins of Slop Editor is completely AI-built. All of its source code, its tests, the build scripts, this manual and its graphics – the editor’s logo and icon – were created by Claude, the AI model made by Anthropic, working as a coding agent (Claude Code). I didn’t write any of the code by hand. The one exception among the graphics is my company’s LT Design logo: I made it myself, without AI.

How it was made

I wanted an editor for my Sins of a Solar Empire mods, so I had Claude build one. I set the goals and the rules – keep the game’s files exactly as they are, write nothing but the mod’s own files, use the game’s own tools for binary files – tried every version on my mods, and reported what was wrong or missing, often with screenshots. Claude planned the work, wrote and rewrote all of the code, wrote and ran the tests, built the releases, took the screenshots and wrote this manual.

The name is honest about that: “slop” is what AI-made content is often called. The editor is tested – more than two hundred automated tests run against the real game’s files – and I use it on my own mods, but nobody has read every line the way a human author would. Back up your mods, and read the code with that in mind if you build on it.
