"Well structured + tested". Who would know? The diff is almost 200k changed lines. Good on them for saying no to this nonsense.
There's a good chance the actual needed implementation is less than 20k lines (I've found that LLM bloat grows exponentially), but even that's a stretch to review and accept wholesale.
I'm the person working on that fork. Yes, it has now diverged 200k+ lines, but half of that is specs, research and documentation and includes a month worth of work.
The comment in question was a small feature of about 1.5k lines changed and it was solidly tested.
Eh, fair enough. 1.5k is reasonable. Have you tried just writing it yourself instead? It's likely it'll be less than 1k lines and you should have no problems writing an implementation yourself if you understand the structure of the LLM version.
Why would I write it myself? I use Claude code 12 hours a day and I'm really confident with want I'm able to build with it. I use it at work with incredible results. Spec driven development with harnessing is super powerful, I'll never be writing large features hy hand again.
