Yeah of course, same here for formatting. But in the world of LLM agents it's pretty easy to have formatting issues sneak by without the IDE being involved. It's a very quick and easy check.

For type checking, I guess that makes sense if your unit tests are small and quick. At work type checking our entire codebase can take like 10-15 seconds with a cold cache, but running all unit tests takes 20 minutes (and multiple shards in CI). Seems like a no brainer to just run the cheap one more often.
