Tip for anyone writing technical/product blogs: never assume readers know what your product is. They probably came in for the first time from a random link on some site like HN and this is your first (and maybe only) opportunity to get that elevator pitch in. I think this particular example is a good one, in that they immediately provide a one-sentence "refresher" that gives the rest of the post some context.
Might be also worthwhile considering a more memorable/distinctive name, unless of course this is only aimed at those who are actively and aggressively following developments in that space. The post piqued my interest enough to make me vaguely think, hmmm, I might follow that up some time in the future when I'm less busy however if I fail to bookmark it and assuming the name 'slate' loosely sticks in my head, then a Google search for 'slate', 'slate ai' or even 'slate ai agent' isn't going to bring me back to this product again.
