TDD inside the agent loop - theater or actual value?

Why it matters — For engineers who rely on AI-assisted coding, the result suggests that enforcing TDD inside the agent’s own loop does not clearly raise design or test quality, and may even be neutral or slightly detrimental. This means teams might spend effort on prompting agents to write tests first without gaining measurable benefits, and could instead focus on other ways to improve AI output. Understanding where the TDD habit helps or hinders agents helps decide whether to invest in such prompting strategies.
