ATM I feel like LLM writing tests can be a bit dangerous at times, there are cases where it's fine there are cases where it's not. I don't really think I could articulate a systemised basis for identifying either case, but I know it when I see it I guess.

Like the the other day, I gave it a bunch of use cases to write tests for, the use cases were correct the code was not, it saw one of the tests broken so it sought to rewrite the test. You risking suboptimal results when an agent is dictating its own success criteria.

At one point I did try and use seperate Claude instances to write tests, then I'd get the other instance to write the implementation unaware of the tests. But it's a bit to much setup.
