What problem are you trying to solve?

To ensure that the recipes are as clean as possible

Describe the solution you'd like

I think the python checks workflow should also include flake8 + isort + autoflake8.

Linked recipes (like from discourse) should adhere to those as well before merging.

To make this easier, pre-commit can be updated to include the listed items, see prefect-collection-template for example.
