Thanks for the feedback though 
This is our first game so it’s always interesting to hear how people are reading the rules in the wild, we’re already pulling together ideas for clarifying this and other rules in our second print run of the game.
The idea with this rule was to prohibit any kind of communication (including non-verbal, indirect hints etc) about the contents of your hand. There are other allowed kinds of communication, like reminding player about how many cards you have in your hand or that the Tavern deck is nearly empty and so some healing would be good! I think we’ll include some examples of both allowed and prohibited communication in our next print run and/or in an online FAQ.
