But most of those setups are thin wrappers around "You are an expert at"

Mine I have been working on since agents released, and has a different conception.

From an intelligent /do router command to automatically route to skills and agents so you don't have to remember anything.

High context skills, because in my testing it's better to have high context, and you use fewer tokens because it doesn't require turn after turn of working on it and fixing.

ADRs being the central component of everything you do, so that there is a consistent document that all agents get.

And a lot more. It's yet another Claude Code setup, but perhaps it's interesting to you.
