Author here! Happy to answer any questions about the implementation.

How much was built with the AI? An OS is definitely a fun project and the classic x86 is a pretty good platform for that!
I wrote the core architecture and most of the code myself. I used Claude occasionally to help debug tricky issues and understand some concepts, but the design decisions and implementation are mine.

I think AI is a great learning tool when you're trying to understand low-level concepts for the first time.

How did you decide between assembler and C for various parts of the kernel? Some choices are very different from what I would have picked, so I'm curious about your thought process.
My general rule was:

Assembly for anything that HAS to be assembly: bootloader, GDT/IDT setup, interrupt handlers, context switching, and port I/O wrappers.

C for everything else: window manager, apps, drivers, GUI rendering.

Some parts I probably could have done in C with inline assembly but I found writing pure ASM for the low-level stuff helped me understand exactly what was happening at the hardware level.

What choices looked different to you? I'd love to hear your perspective always looking to improve!
