Kavanah for what?
its a complicated question
kavanah that you are aware of the act that you are doing?
kavanah that you are doing a mitzva?
kavanah that you are doing a particular mitzvah?
kavanah that you intend to be yoitzei the mitzvah?
particular kavanah associated with that mitzvah?
when does the kavanah have to be present?
im sure there are lots more variables i cant think of right now, and more that im not aware of at all.
all of the above ones are subject to complex disagreements among the Rishonim
