Try building review skills based on how you review. I built one recently based on how I review some of the concurrent backend stuff one of our tools does. I have it auto-run on every PR. It's great, it catches tons of stuff, and ranks the issues by severity. Over 10 reviews, only 1 false positive (hallucination) and several critical catches. I wish I'd set it up sooner.

Can also after those sessions where they get stuff wrong, ask for an analysis of what it got wrong that session, and produce a ranked list. I just started that and wow, it comes up with pretty solid lists. I'm not sure if its sustainable to simply consolidate and prune it, but maybe it is?
