  3. Our readingThe skill that matters now is not prompt engineering but giving a model a way to verify its own work, and it is the thing people most often get wrong.

    Their wordsI think the skill nowadays is less about prompt engineering and more about figuring out how do you give Claude a hard task that seems a little bit too hard. And then how do you make it possible for Claude to verify its work along the way? And the verification I think is probably the single most important thing that people do not get right
