Running task or role before any playbooks Is there a way to run a specific task or role at the very beginning of every ansible-playbook run?

I'm looking for something that would go into ansible.cfg or something like that, so all playbooks using that file would run a specific task at the beginning.

My intention is to use it for doing some verifications: for example, "is the local host listed on the inventory?  If not, perhaps I'm using the wrong inventory".

I could import or include such a role in every playbook, but I want it to be automatic, and to work even for playbooks that don't know about that role.
What you are looking for is the meta/main.yml in the roles of Ansible.

So make your every playbook (the ones you want to run after a task/role) as a role itself (to make it secondary execution) and what ever task/role you want to run before it should be added to the meta/main.yml of all the secondary execution roles. This would make all your roles execute the role mentioned in meta/main.yml
