It's not YOLO, but auto mode in Claude Code does reduce the amount you have to approve significantly. And frankly, without it, progress is constantly interrupted by permission requests. It's all I use. Don't even really switch into Plan mode manually anymore.
I find it still asks too many questions. Unless I'm not triggering it as often as I think I am.
What questions? When I go into auto mode, it doesn't come back until it accidentally/intentionally tries to slip the guardrails, or completes the task. My prompt will generally include information on what it's allowed to do to accomplish the task, where to test, etc. Simple, but effective.
