It‘s at the very bottom of the readme, below the MIT license mention. Yes, it’s there, but very much in the fineprint. I think the easier thing to spot is the CLAUDE.md in the code (and in particular how comprehensive it is).

Again, I love Claude, I use it a ton, but a topic like database cloning requires a certain rigour in my opinion. This repo does not seem to have it. If I had hired a consultant to build a tool like this and would receive this amount of vibe coding, I’d feel deceived. I wouldn’t trust it on my critical data.
