You make the framework and it colours in the lines. If you don't draw the pattern first you're going to get a kindergarten mess. There are times I'm amazed by its suggestions but it will also cheat and "lie" and if you're not paying attention, you'll miss it.
But these days many tasks for me consist of: I need this, look how I did it here before, and follow this exact pattern through to the end and write tests, too. And the results are usually exactly what I would have done. Because it is an excellent mimic. But if I hadn't put the work into the framework, it would be awful.
I’ve ended up with tests called stuff like “foobar successfully returns impossible value that suggests programmer error” lmao
Conveniently, when it then changes the original implementation, the tests don’t fail!
