Thank you for the data point.
To give back as much as I can, I use the two built-in CC review processes when appropriate. But, those only do "is this PR good code?"
Far too late did I finally roll my own custom review skill that tests: "does this PR accomplish what the specs required?"
If I could ask for one more vanilla CC skill, it might be that. However, maybe rolling your own repo-aware skill via prompt is better?
