I was thinking of it as a way to turn unstructured text into structured output.
Eg. "This is a chat message in my stream.place channel. Does it seem to want a response from me, the owner of the channel? {{event…message}}" + (JSONSchema requesting) a boolean response, available as Airglow variable.

BTW, I'm almost done implementing ~ all of JSONSchema in stbl, which will then transfer into the engine behind tibblify. All of this is why I wrote stbl and took over tibblify; I needed to be able to cleanly parse api responses for beekeeper 🙃
