Do you think using LLMs is a skill?

I have been using them since they became commercially available, but it's hard for me to think of these as a real skill to develop. I would never even think of putting them/prompt engineer as a skill on a resume/cv. However, I do see many people fall victim to certain pitfalls that are remedied with experience.

How do you all view these? Like anything you gain experience with use, but I am hard-pressed to categorize usage as a tool with a skill level.
