I think this should be renamed "I know when you're vibe coding with a last generation LLM".

Claude 4 Opus would not make any of the mistakes mentioned, because it knows and understands everything in your codebase. It would know when there's an existing utility function for that particular task, or that you prefer a functional rather than OOP approach. You say you want developers to care about the code they write, well, this is the next best thing; I believe it's as close as we'll see to a machine being able to "care" in my lifetime.
