But you know what you like, and you know what bothers you, and the good news is that you don't have to one-shot a solution. You can create a skill and refine it over time. As you test and/or use it, identify copy you don't like and tell the LLM what you prefer instead, and ask it to distill and generalize that feedback into the skill.
Writing is similar. I enjoy well written texts, but that doesn't mean I can write them myself, or can tell an AI how to write in that way.
Right, but you know what you like. The point is that you can tell the chef "too spicy" and send back the plate until you get what you want. He can then remember that, since you're his favorite regular.
I just went through this with a release notes skill. I brainstormed with the LLM about what I wanted, edited initial results when I saw something I didn't like or could be made better, than asked the LLM to capture that in the skill. Now I almost never need to touch it.
