Today I released Django Doctor: it's a bot that suggests fixes to any code smells it finds in your GitHub Pull Request. Just click "approve" to commit the fix for low effort code improvement!
I made this after realising I can automate some of the dev effort during code review: there are some checks we perform during code review that a bot can pick up - allowing us to spend more of our time on things bots are not good at.
Plus it suggests the fix so it does not show problems - it comes to table with solutions ;) Much quicker than reading a linter error in CI, locating the line in the file, fixing it, commiting and pushing to remote.
