Describe the solution you'd like
We already have a command to run the linter locally. It would be great if the linter could run on CI.
Today we have a considerable amount of warnings, I'm not sure if we should fix them or apply some kind of checkpoint (to run the linter after a specific commit.

I would like to remove all of warnings that can possible, in my option, we can to add this verification before the build stage.
Later, we can create a conduct code or similar thing, for those who want contribute to the project, follow the rules.
