Thanks for writing this up.
I just woke up recently myself and found out these tools were actually becoming really, really good. I use a similar prompt system, but not as much focus on review - I've found the review bots to be really good already but it is more efficient to work locally.
One question I have since you mention using lots of different models - is do you ever have to tweak prompts for a specific model, or are these things pretty universal?
I don't tweak prompts, no. I find that there's not much need to, the models understand my instructions well enough. I think we're way past the prompt engineering days, all models are very good at following instructions nowadays.
