oh for the app hmm i see what you mean. I am just following the code consistency though, the documentation right now was creating and using mostly $fullcommand constructed variable because that is coming from the description of the command. It does not talk about the application from which is called. So it is all strictly talking about the commands. And is not just update. The name by default as initialized in constructor if not overridden would be php app composer:update. So this fullcommand is just the composer:update part. I think in sculping there is an override of the part of the composer: prefix. So it would just be update, so it is totally fine. :+1: good to merge
