Repeat or not repeat actions buttons?

I have a discussion with my boss about repeating the same several action buttons in different parts of the application. The actions are: add subtask, add note, add meeting, add message and add file. I have the theory that we can´t load the app with so much buttons in different parts if we are going to show the same buttons. But he says it will help to the user to do the experience more comfortable..... Here it is an example: https://imgur.com/a/7CLEd In the example, the card of the level 1 is the project in general, and in the level 2, we can see the project more in deep (you can see there a subcard, where we put the action buttons). Even more: we have a green button add in the left up side column to do again the same actions....

What do you think?

Thanks and regards, Alejandro.
