I guess it depends on how close to the code you want to work. I find that I lately talk only about the features and UX and can leave the coding details completely to the agent. That might not work in every project, but I suspect it might work more often than people think because it's hard to adapt to the quickly increasing capabilities of LLMs.

I think a good habit is: Try to make the agent fail at least once a week with a too ambitious request. This got surprisingly hard lately :)
