Framework for writing custom linting-rules in python?

^{I hope this somewhat open-ended question is allowed, I have used SO a lot and I would not post it there, but I have seen open-ended questions on this site}

I have a situation where custom linting-rules for python-code would be very helpful^[1].

Some random examples of rules I want to enforce:

• All imports must be absolute, at top-level and reference existing modules.

• All classes that define a class-variable event_map must inherit from proprietaryOrm.Object and event_map must have a certain structure

• ctx.set_object_result and ctx.url must not be called in the same function

So this is not random clean-code rules, this is very specific and I need to code them up using a combination of techniques, mostly AST-inspection and dynamic inspection of live-objects^[2]. The question is not how to write these rules but where to put them. If I write a unittest, I put it in a test-framework. Now I don't have to worry about things like the test-runner and IDE-integration. If I write a linting-rule, I put it where?

I have not found any 'linting-framework' online, but maybe I just did not find it. Finding such a thing would be ideal. But if there is nothing like this, is there at least some standard for integrating linters into IDEs? "Output your linter-violations in this specific format and this standard plugin can pick it up". Or can you bend a regular test-framework like pytest to do this?
