Sorry, it's not engineering, it's cargo-culting as engineering. Engineering is based on improved formal understanding of the process, not magical incantantions. And yes I do use these things. It's like saying copy-pasting code is a skill.
Until you think using agents is a magical incantation, you will not be able to actually engage with it and develop the skill.
As evidence that it is a skill beyond copy paste, you should look around (online and offline) at the really smart people who are able to derive so much from it.
