I'm curious - is there a tool for auto-fixing these that I'm not aware of or are you doing these by hand? Wanted to know if I could do it myself quickly instead of calling on you - I feel bad :(

No worries, Steve :)
I do it by hand when I run the following command locally:

ament_mypy --config=tools/pyproject.toml
