Not really. The "Software Engineering at Google" book[1] has a whole chapter on it with screenshots.

Gerrit, Reviewable and Phabricator are very similar, except that Critique is much more polished.

Having used all three, Gerrit works best and the new UI is starting to look pretty good. Reviewable has great UX, but inherits some of the disadvantages of GitHub PRs.

Same for me. I think it's https://books.googlecom/books?id=WXTTDwAAQBAJ. It has no preview of the Critique-related fragments.

It's a reimplementation of an earlier system called Mondrian, which you can find some information on.

I used Mondrian for the last couple months it existed, and I recall critique being fairly different.

I think they kept the same keystrokes, though.

That is one nice thing about Critique is although it's a webapp you can drive it pretty much entirely by keyboard. It has the feel of an old usenet newsreader like nn, in a way.

Here I'm sitting here thinking could I draw it from memory?

It went through a re-design recently. I don't think I would call it a well-guarded secret though, if you look at Phabricator's Differential, it is very similar [0].

Reading through that page it seems like every single component is an unrelated, seemingly random, “cute” name. Are cli, triggers/actions, and rules too generic? Out of context, what meaning do Arcanist, Maniphest, or Herald have?

But yeah... even I find the names difficult to handle and remember, even after using Phabricator for more than 4 years now. Nevertheless, it is a great piece of software, especially the code review process is top-notch.
