If you dig this then you may like to install the bot on your GitHub pull requests
The closest to existing tools are: https://github.com/lamby/django-lint/ https://github.com/PyCQA/pylint-django
but- you have to set those up yourself in a CI and update them manually and not have the cool feature like PR integration, "fix it for me" (you would have to fix it yourself like a barbarian), the slick companion website with the beautiful blue progress bar :)
With Django Doctor you just click "install on GitHub" and boom, you get updates at no effort, and if you like the suggestion Django Doctor makes you just click commit
