Unfortunately, the katas are in a sad state due to the pace of changes in IntelliJ, and the change in the courses format in the EduTools plugin.
I did the changes for the Python Beam Katas, and after that experience, I think we need to move away from the EduTools for the katas. I would favor an option based on just some unit tests, that would pass when the exercise is correct, with some documentation to be browsed locally. I think the Beam Playground would be the ideal platform for running those tests, and it could even have a panel for visualizing the documentation (description of the exercise, links, etc). That would make the Katas more maintainable too. Right now, there are sometimes changes in the Katas related to the playground that break the Katas in Edutools. I am not sure when (and if) I will be able to work on something like that, but I will be happy to collaborate with anyone who has the time to implement it. The katas are already based on unit testing, so the changes would not be large.
