I mainly use Claude Code for things I know, where I just don't want to focus on the coding part. However, I recently found a very niche use. I have a small issue with an open source project. Instead of just accepting it, it occurred to me I can just clone the repo, and ask CC to look into my issue. For example, I was annoyed with Helix/Zed that replacing parameter in Zig code only works for function declarations, not function calls. I suspected it will be in the tree-sitter grammar, but I let it go through the Zed source code, then it asked for the grammar, so I cloned it and gave it access to that, and it happily fixed the grammar for me and tested the results. It needed a few nudges to make the fix properly, but I spent maybe 5 minutes on this, while CC was probably working for half an hour. I even had it fork the repo, and open the PR for me. In the end I have an useful change that people will benefit from, that I'd never attempt myself.
