I think you have conflated the idea of an OS and kernel. A kernel generally handles calling conventions, device driver conventions, process conventions, memory allocation methods, etc. An OS just uses a kernel which has already decided on those conventions.

I have always thought of the kernel as being part of the OS, but maybe I'm wrong?

  Some people think the kernel is the OS, some people think of the kernel as part of the OS, and apparently slimsag thinks of the kernel as something different than the OS. They're just different naming conventions.

Personally I would argue the term "OS" is simply not that well defined, and the readme makes no attempt to clear that up which I think leads to confusion. What actually defines an OS vs. not an OS is a pretty blurry line, and more-over when someone talks about "OS development" 99.9% of the time they're talking about kernel development. So naturally calling something an "operating system kit" that lets you "create operating systems" makes you think of kernel development. That said, I read the whole readme linked here, and not once does it actually explain what an 'operating system' is, so I personally think that's just a failure on their part in picking a name and explaining what exactly the intended use of their project is. If instead of using the term "operating system kit" they used the term "baremetal/kernel application SDK" (or something along those lines) I don't think anybody would be nearly as confused on what it is. But I'm not entirely sure that's a good name either because I'm really just not sure what you're supposed to use it for. I read the whole readme, but I'm still at a bit of a loss. Don't get me wrong though, I still think it's a cool project, but mostly just for the code making up the 'Cosmos' kernel rather then the 'develop your own OS' aspect.

  > Personally I would argue the term "OS" is simply not that well defined An “operating system” is a combination of what the user sees, what developers see, and what devices see, I'd say. If one wants to refer to the GUI, CLI, API, SDK, DDK or the kernel individually, just use those terms. :)
