So just for work then or personal projects too? For work I can understand but for personal projects I haven't necessarily gotten more success out of AI than my own code, to be honest.

In terms of personal projects, I use my own custom Ruby X11 window manager, and when I moved and got the office space for an extra monitor, Claude Code wrote the basics of the multi-monitor support by itself.

It's notable to me because there are to my knowledge no other Ruby wm's (there's at least one that allows scripting with Ruby, I believe, but not the whole codebase), the X11 bindings are custom (no Xlib or XCB), and there are few great examples that fits into the structure of my wm. Yet it made it work. The code was ugly, and I haven't committed it yet as I want to clean it up (or get Claude to) but my priority was to be able to use the second monitor without spending more than a few hours on it, and starting with no idea how multi-monitor support in X11 worked.

Since then, Claude Code has added Xinerama support to my X11 bindings, and selection support to enable a systray for my pager, and written the systray implementation (which I also didn't have the faintest clue how worked, and so had Claude explain to me before starting).

I use it for work too, but for these personal projects priority has been rough working code over beauty, because I use them every day and rely on the features, and want to spend as little time as possible on them, and so the work has been very different from how I work with Claude for work projects where I'll work in much smaller chunks, polish the result etc.
