I'm not doing adversarial critiques of the code; I'm doing adversarial critiques of the designs and plans. If it's still outputting bad code when it comes to the implementation, I do an interrogation round to find out why it's choosing that way, then update the principles, standards, or linting tools to fix it.

The skill I wrote did both. Design would go through an adversarial round, then a signoff by me, then implementation, then critique rounds by agents prompted to specific types of issues. And even then, LLMs were still struggling to put together complicated bits of code.
