If you're telling an agent how to implement something, congrats! You're doing it right and should go on a walk while it's being implemented.
If the agent is telling you how to implement something, you should probably take a walk to digest it, and come back to tell that implementation-machine what to actually do so you can take another walk while it's being implemented.

I can't imagine needing to ask for permission or having to justify myself every time I personally wrote code. That definitely sounds like hell
But in any case, in that hypothetical scenario, just automate your day job and spend time coding a side project you're passionate about. You might have to spend 10 minutes out of every hour prompting, but hey, that's still 400 minutes a day for your side project of choice.
