it helps to be able to describe something visually with a lot of accuracy (ie, not "a button is 2px off", but "the icon for this button is too close to the text and not vertically centered", etc). it also helps to be able to just step in and correct a design yourself.
thanks for the comment, step in is important but I was thinking about Claude Code - I actually usually don't step in that much. Would it make sense to have human in the loop or it's better to let the Agent decide everything and just show the result?
