It would seem you don't care too much about verifying its output or about its correctness. If you did, it wouldn't take you just an hour. I guess you'll let correctness be someone else's problem.
Your wild assumptions and snarky accusations are unnecessary. The library is for me to use; there isn't a "someone else" for me to pass problems onto. I then did what I usually do — start writing real code with it ASAP, because real code is how you find real problems.
I developed the library interactively, one API call at a time, in a manner akin to pair programming. Code quality was significantly better than I'd expect from $2000 worth of a GOOD mid-tier programmer — the code was well written, well organised, and comprehensively annotated. The code wasn't perfect, but a majority of faults had a basis in the underlying documentation being wrong or ambiguous.
The $20/month for Cursor Pro literally justified its cost in less than 10 minutes.
I don't know the OP here, but in my experience a junior dev at an average company would likely not do much more than the AI would. These aren't your grandfather's engineers, after all.
A junior dev wouldn't have produced output of such consistency, and they wouldn't have annotated their code nearly as well. The majority of code was better than I'd expect from a junior, and the comments were better than I'd expect from the majority of people at every skill level.
