Breaking up a giant PR can be a tedious, time-consuming hassle, and in the past I could sympathize in practice if someone had a giant PR they didn't have time to decompose once they got it working.

But it's also the exact sort of thing that LLMs are literally perfect for in my experience so there's really no excuse anymore. I've never seen Claude fail to turn a 5k PR into a well-decomposed Graphite stack.
