The more I use Claude Code, the more aware I become of its limitations. On the whole, it's a useful tool, but the bigger the codebase the less useful. I've noticed a big difference on its performance on projects with 20k lines of code versus 100k. (Yes, I know. A 100k line project is still very small in the big picture)

I think one of thr big issues with CC is that it’ll read the first occurence of something, and then think it’s found it. Never mind that there are 17 instances spread throughout the codebase.

I have to be really vigilant and tell it to search the codebase for any duplication, then resolve it, if I want it to keep going good at what it does.
