See #2969 for some examples of Claude Code rushing into things despite explicit rules about needing to ensure correctness first. In general Claude Code seems to be constantly prioritizing action over deliberation, attempting to fix bugs based on the first inkling of what might be causing it instead of at least trying to confirm its hunch, or investigate more properly, etc. I found it extremely counterproductive - it messes up code in ways that often takes extra effort to undo (I try to checkpoint periodically as it is doing its task, but sometimes I am doing my own thing, not watching over it to prevent it going off the rails), does things that it was told in 10 different ways not to do, etc. I wonder whether part of the issue is the system prompt that makes it way to eager to get to the next step. I understand there are cases when this is reasonable, but definitely not for me. I would have preferred a toggle between the current "get to the next steps ASAP" version and "go slowly and make sure not to overlook things" mode that would be way better for me.
