Cool accomplishment in and of itself but hard for anyone here to really give you any criticism or feedback without understanding where it excels and how to work with it.
I think this clearly describes what was the goal.
Less than a minute and I know how to use it. It's not complicated. The source code is available and fairly easy. If you can't figure out how to use it in a trivial amount of time, you aren't going to be able to offer anything of value. When did HN go from being about interesting stuff to making bold, ignorant statements like "There is no way to look at this codebase and give any kind of feedback one way or the other without that understanding."
You should know better.

I do find the source to be well organized and quite readable. Especially if you runs the commands in the cli and then trace how they are each implemented.
