I've seen a couple of talks on DSPy and tried to use it for one of my projects but the structure always feels somewhat strained. It seems to be suited for tasks that are primarily show, don't tell but what do you do when you have significant prior instruction you want to tell?

e.g Tests I want applied to anything retrieved from the database. What I'd like is to optimise the prompt around those (or maybe even the tests themselves) but I can't seem to express that in DSPy signatures.
