I'm wondering if the obvious (and stated) fact that the site was vibe-coded - detracts from the fact that this tool was hand written.

Human author here. The fact that I don't know web design shouldn't detract from my expertise in operating systems. I wrote the software and the man page, and those are what really matter for security.

The web site is... let's say not in a million years what I would have imagined for a little CLI sandboxing tool. I literally laughed out loud when claude pooped it out, but decided to keep, in part ironically but also since I don't know how to design a landing page myself. I should say that I edited content on the docs part of the web site to remove any inaccuracies, so the content should be valid.

To be less abstract, it was written by David Mazieres, who was been writing software and papers about user level filesystems since at least 2000. He now runs the Stanford Secure Computer Systems group.

David has done some great work and some funny work. Sometimes both.

Doesn't detract from it. The jai tool is high-stakes, the static website isn't. The tool is designed to be used with LLM coding agents, so if anything it makes sense to vibecode the website, even better if the author used jai in that.

Sigh, I'd still have preferred a basic HTML page with hand-written succinct information instead of this crap verbosity.
