I would say prompt engineering, in the sense of people claiming you need to include in every prompt magic incantations like "You are a senior engineer from a superintelligent alien species" and "take a deep breath and make no mistakes" doesn’t really do that much for everyday work I feel or they are all already included in the system prompt maybe. I reckon it can still edge out a few percentage points in automation.

What actually matters is the ability to communicate well in general, not anything LLM-specific. Being able to state what you want clearly and unambiguously, and having a sense for what additional information you need to dump, even when the other side claims they already have everything they need.
