I can't really say I agree with this, although I also hate the phrase "agentic engineering".
I'm working on a licensing system for a product I'm building. I've used Claude a little bit to help out with it, but it's also made a lot of very dumb decisions that would have large (security!) consequences if I didn't catch them. And a lot of them are braindead things, like I asked it to create a configurable limit on a certain resource for the trial version of the application. When I said configurable, I mostly meant: put the number in a constant so I can update it later. What Claude thought I asked was "make it so the user can modify the limits of the trial version in the settings panel" (which defeats the entire purpose of a free trial!). Another thing it messed up recently is I was setting up email-magic-link authentication. It defaulted to creating an account for anyone that typed in an email, which could allow a bad actor to both spam people with login requests (probably getting me kicked off Resend) or creating a lot of bogus accounts.
These things do not think. You cannnot outsource your thinking to them.
