Hope the next public beta gets the shortcuts app, I’d like to play around with it.
Unfortunately, it doesn't come with the beta. Right now, paid developers can request it from Apple (via TestFlight) and then its up to Apple. That doesn't mean it won't be available to test later this summer for public beta members, but not sure how they'll do that since it seems to not be part of the stock app package (Stocks, Weather, Reminders, Notes, etc...) but a downloadable app.
In the meantime, download Workflow. That gets you most of what Shortcuts can do (right now). If you learn Workflow, you'll know Shortcuts right out of the box.
