Pretty much this. Because anyone using the tool would understand what to
enter. There are things like opponent, result, tournament and rating
without which there wouldn't be a need to use the tool in the first
place. 
The only fancy thing I've done in the cli version is for it to remember
some options the users has made previously (like Tournament defaults to
previous post when entering several games)

Basically afaics at this time it is to ensure someone doesn't enter an
incorrect value by mistake (like '' for result, or rating without it
being an integer) and then letting the user correct the entries before
committed.
