However, I found the same problems with agents that it has with humans (usually with humans it isn't TDD but code coverage requirements). The problem is the tests are now written to satisfy a bureaucracy rather than to properly verify the code. And there are real studies that point out the low value of these types of bureaucratic testing requirements. For example, when models are just required to write a test file, they don't produce a better result: https://arxiv.org/abs/2602.07900
I wrote a /verify skill that focuses on properly verifying code and I am finding it works a lot better. I do need to revise it now- in practice certain parts of the skill are doing all the heavy lifting and others are more dead weight. But it does seem to be properly orienting the agents towards finding defects. https://github.com/gregwebs/skills-sdlc/blob/main/skills/ver...
