Author here. I am actually participating pretty causally at advent of code and don't try to get into the global leaderboards (I wouldn't be able to, even if I would try).

I build the tool for myself last year because I like the comfort of not having to switch between terminal and browser. As I wanted to use it this year again so I decided to put it into a separate repo and to share it here.

But I see the point that this a special kind of laziness not everyone can relate to :)
