I am somewhat curious about this though. It seems like this kind of workflow would be more flexible than a dumb template, but in practice I am not so sure these days. The back and forth of it gets slightly tiring and you start to miss the simpler, unambiguous tools. Perhaps its just something about the apparently extreme complexity of prompt engineering, but the feeling of freedom/flexibility in the prompt based workflow at the very least feels comparable to a good template based one.
This is not to wave away the other things it can do like generating copy.
