Use your existing desired style as exemplars

My team solved this by creating a PR draft skill that clamps the length of the description to 3-5 sentences max. Those 3-5 sentences must only say WHAT is changing and WHY.

I find it to be far more useful than when humans wrote PR descriptions. Many engineers didn't write one, and those that did were poorly written... this problem is mostly solved for us.. it still has LLMism speak.. but it's useful enough for me to get the context I need to do my review.
