It doesn’t really matter in the long run. Just be clear about it. And then be consistent.
You can go for narrow:
What will you do and what is your trigger?
You loose your movement and you must act before the end of my (my meaning you as the GM) turn. But you can’t take a breather.
I recommend broad, and if allowed to wait till after your turn to decide to take a breather…that would all of my breathers.
I’m sure there are other little things you’ll want on the exclude list, but those are the only ones that stand out in my head at the moment.
Also, given the nature of round table initiative…if 2 players want to do a joint action…let them, so there is no waiting till billy hands me the potion so I can throw it at the principal.
