I'm thinking about subscribing to the max plan for Claude to assist with my Golang projects. Some of my projects are pretty extensive, with over 2,000 lines of code. I'm curious if I should divide these large files into smaller ones to make them more manageable. Does Claude actually pick out the necessary functions from my code without needing the entire file?

Claude Code is really capable of handling specific parts of files, no matter how large! I've tested it with files as big as 5 million tokens, and it worked great. However, for maintainability, it’s best to keep your files around 700 lines or less. Generally, under 1000 lines of code is where it performs really well.
Absolutely, splitting your files is a good idea! Just ask Claude to help you with the organization.
You should definitely tell Claude to help modularize your code. A good rule of thumb is to keep each file under 500 lines as a best practice.

Totally! Why didn't I think of that before? Thanks for the tip!
