Alternatively, record a video that showcases it.

Ok, will do that now!

I know we all think of bad things when we hear "short form video" but short demos can do a LOT for any project, shows the user how its used, what it looks like, what it solves, etc all in anywhere from 15 seconds to a couple of minutes, doesn't need to be ultra fancy, screen recording is fine. :)

Since there is no GUI here, I feel like a simple plaintext chat transcript would be both 100x smaller and 100x easier to read. (Not to mention accessible.)

Sure, and we've seen those terminal screen recorders that give you back a replayable demo, that could work too.

Yes, a demo might be a good idea.
