 mypy is [designed for gradual typing](https://mypy.readthedocs.io/en/stable/): by default, it [skips functions without annotations](https://mypy.readthedocs.io/en/stable/getting_started.html#dynamic-vs-static-typing), so you can add type hints slowly. Check in one config file, [run mypy in CI](https://mypy.readthedocs.io/en/stable/existing_code.html#run-mypy-consistently-and-prevent-regressions) so new type errors don't land, and aim for `--strict`.
