TDD is more important than ever

Why is verification so important? Because, if you tell an agent to do something that it can't independently verify, then—just like a human developer—the best they can do is guess. And because agents work really fast, each action based on a guess is quickly succeeded by an even more tenuous guess. And then a guess of a guess of a guess, and so on. Very often, when I return to my desk after 30 minutes and find that an agent made a huge mess of the code, I come to realize that the AI didn't suddenly "get dumb," but rather that an application server crashed or a web browser stopped responding and the agent was forced to code speculatively and defensively.
