I have a custom harness that runs in a macOS VM. It has e-mail and its own accounts. I assign it tasks in Linear, it does them and spins up PRs for me to review. This works pretty well, generally. I have to spend time writing stories and doing code review, but I don’t have to follow its (their — I have 3 of them) every move.
Regardless of the sport you practice, you probably need to be doing some form of periodization. You can’t go for PRs every session because at some point your body stops being able to recover => you get hurt.
