Every systems engineer at some point in their journey yearns to write a filesystem. This sounds daunting at first - and writing a battle-tested filesystem is hard - but the minimal surface area for a “working” FS is surprisingly small, simple, and in-distribution for coding agents. In fact, one of my smoke tests for new coding models is seeing how good of a filesystem they can one-shot! At some point, I had quite a few filesystems lying around - and coding models were getting pretty good - which made me wonder if the models were intelligent enough to actually model the filesystem engine itself?
