Nice, I didn't know about those and I ended writing my own solution:

    def canAdd(self):
        interaction = ZopeSecurityPolicy()
        return interaction.checkPermission("zope.ManageContent",

I'm trying to know if the user can add an item to a container. I don't
know how to do that with zope.security.canWrite. I tried with

zope.security.canWrite(self.context, '__data') 

since my container inherits from SampleContainer and the '__data'
attribute is a dictionariy like objet where the children are stored. I
get a ForbiddenAttribute exception with that code.
