gqylpy/systempath ? reverse-engineered prompt

Build me a Python library for working with file paths, folders, and files in a more natural way.

I want a simple object oriented API with classes like SystemPath, Directory, and File, so I can navigate paths with bracket style access and combine paths easily. It should support absolute and relative paths, and have a strict mode that checks whether a path already exists when it’s created. I also want the usual file and folder actions, like reading and writing file contents, appending, clearing, creating folders, deleting, copying, moving, and walking through directories.

Please make it feel clean and easy to use, with good defaults and helpful errors. Keep the public API friendly for Python developers, since the goal is to make file and directory management much less annoying in scripts and small tools. If you need to, look up current Python best practices for path handling and packaging before you finish.
