No, they actually have the files pane on the left, live preview mid-top, terminal errors mid-bottom, and the agent on the right. no looking at code.
Cursor has a "yolo mode" where you don't have to click accept for tooling even for system commands and people whitelist commands like sudo, su, and rf :))) I wish I was kidding.
The vibes are coming from changing to actual product (design, UX, functionality) and not from the code. The code in fact doesn't matter at all. At this point that's only ok for throwaway prototypes (but for those it's quite wonderful), the more the application requires careful maintainable engineering, you need to read every line and leash the LLM. It's a bit of a continuum between the two edges in reality.
