Bizarre because a quick look at the code and commit log shows it was likely 100% coded by AI, so the author is not trying too hard to hide it, but they also seemed to forget to mention it anywhere in the README or the blog post.
All of the code is imported in 1 commit. The rest of the commits are deleting the specs that I guess were used to generate the code. There’s one commit adding code which explicitly says generated by Claude code. There’s basically no chance the whole codebase is not AI slop.
