> Mypy exists. Mypy is optional. Optional means it’s not there. I’ve never seen a Python project where mypy covers 100% of the code with strict mode. I’ve seen hundreds where it covers the 20% someone added last quarter. The other 80% is Any, all the way down.

This is your project, is it not? Can you not simply tell the agent to cover 100% of the code?

Notably, types in TypeScript are also optional, but LLMs don't seem to have any problem generating fully type-safe code without `any` (though you do need to gently nudge them on occasion, or run a linter that forbids it). I don't see why they'd choke so hard on Mypy.
