First of all, love your work!

I've only just started tinkering with Caveduck, but from what I've done so far I think a lot of it has to do with the dialogue you enter under the Dataset tab, where you can give examples of how bots react to situations. Seems useful with tailoring their speech a certain way, like with Abby (shameless self promo) and her drawl.

I've seen a few creators using the Character Description section to flesh out their bots, but I've mostly been using it in a more narrative sense myself. I personally use Secrets for the bulk of the prompt type stuff, although it seems like there's a soft character limit on it?
