Everyone wants an AI second brain, but almost nobody talks about the fact that there are different levels to building one, and the highest level isn't always the right one for you. 

In this video I break down all five levels of a Claude Code second brain, from a simple CLAUDE.md router all the way up to an always-on autonomous system, using my real Herk2 project as the example. 

The goal isn't to climb to level five. It's to find the lowest level that actually solves your pain so you stop re-explaining things and your agent always knows where to look.
