If I may "yes, and" this: spec → plan → critique → improve plan → implement plan → code review

It may sound absurd to review an implementation with the same model you used to write it, but it works extremely well. You can optionally crank the "effort" knob (if your model has one) to "max" for the code review.

Can you give a little more detail how you execute these steps? Is there a specific tool you use, or is it simply different kinds of prompts?
