I'm probably a bit late to the party. But I just want to tell my short story, because I'm amazed. I have several open source project and especially one that I use every day. It's not a project with huge user-base, but there are some. Some of the user has posted issues, which I have wanted to take care of, but time, is always an issue. Debugging, trying to get into issues other users expirence while I don't, is always harder to get grip of.
So, today I fired up Claude Code, told it about my project and during 2h (including manual review of the generated code), I've fixed several issues. I even managed to get in new features I have wanted as well!
https://github.com/Lallassu/gorss is now v0.5 thanks to this.
