We know Skaia likes to f*** with the kids, killing their world, making their guides semi-useless at times, that sort of thing.

I mean, Skaia doesn’t really do any of that. SBURB is the mechanism through which the Universe reproduces, the process is built into the Genesis Frog itself. In the Universe of Homestuck, there’s no alternative to any of it, a world’s gotta die for it to birth a new Universe, and Skaia, while at the core of the Session, and as the cradle of the new Universe, seems more of a byproduct of this process. Similarly, all Sprites share knowledge of the game to help the players in their adventures, however useful or useless they may be is more regarding whatever the Players themselves prototyped.
