How is this a change in job description? It may be a failure of imagination on my part, but it sounds like you're still doing what you have always done - you've changed the how.

Right. And in a similar vein, its very easy to replace a lot of low-effort outsourcing / junior-dev assignable tasks. I still need to describe the problem and clean up the answer, but I get the answer immediately and I can re-prompt for it to fix it immediately.

Do you feel yourself becoming disconnected from your skills? I used gpt extensively at one stage and I felt very rusty getting my hands dirty in code again.

I don't. But that's probably because I'm very opinionated about the implementation details, so I'm scrutinizing and tweaking its output a lot.
