I’ve reviewed and worked on a lot of vibe coded apps (I’m an engineer, 20 YOE).

I can basically split it into 3 groups.

1) Pure vibe code. No software experience.

2) AI with someone who knows the software development process and some things about software, but can’t code.

3) Engineers using AI assistance, reading/reviewing code, forcing structure.

If someone can pay to replace #1 with #3 it’s very worth it. The quality between each of these tiers is enormous.

I actually got curious and asked AI to look at each module in a codebase, and tell me about who wrote it without looking at git.

It successfully profiled all 3 of these groups and correctly attached them to the right module.

Thanks for writing this. In my refactoring process I also start with code profiling. Opus is good, at finding hand written code, which sometimes is a good starting point of understand the codebase in general.
