Andrej Karpathy:

"The value of the system is in the edges, not the nodes."

In a short field note, he lays out 9 rules for a knowledge base that maintains itself. Claude keeps the notes.

Obsidian shows the graph.

3 layers, 3 owners. raw belongs to you and never gets edited. wiki belongs to the model. 1 schema file holds the rules for both.

This isn't RAG. RAG re-derives the answer every query and keeps nothing. Here your sources compile once into linked pages and compound.

You feed 1 source at a time. The model files it, links it, updates every neighbor it touches.

Start with 10 sources, not 10,000.

More useful than a $500 PKM course. Save this.

Claude + Obsidian stops being a folder. It becomes a second brain.
