Description

Currently, we have a lot of rules that are not very aligned with .pyi files.

Here are some of them:

  • ... usage as a placeholder
  • complexity rules like number of arguments, methods, etc (we cannot control things like it in annotations)

And probably others as well.

What we need to do here is ignoring this violations when filename has .pyi extension.
And better docs about this case.

Research direction

Start by reviewing the rules related to .pyi files and the related configuration in setup.cfg. Identify violations that should be ignored when the filename has a .pyi extension, including placeholder and complexity checks, and update the documentation to explain this behavior. Done means the relevant rules are skipped for stub files and the case is documented.
