I just gave my Claude Code second brain a massive overhaul. Here are the 3 systems you need to build one for yourself or your business. 1. A Knowledge base in Obsidian (but any file system Claude Code can see works) 2.Karpathy’s LLM-Wiki document to structure how your AI organizes information 3. A self-learning skill that finds gaps in your new brain and fills them on demand. If you want my skills as a starting point, comment BRAIN and I’ll send it to you. #claudecode #claude #aitools #obsidian
Transcript excerpt
I just gave the second brain that I built for my cloud code a massive overhaul. And here are the three systems that you need to build one for you or your business. The first step we're going to take is for our knowledge base and we're going to use Obsidian as the software. But you could use this in almost any system even notes as long as your cloud code can see the file structure. Now that we have that installed, here's where the game changer is and we're going to grab this document from Carpathi right up here and this is LLM Wiki which he outlines a certain type of file structure for your cloud code to use when building your knowledge bases inside of Obsidian. Once we use that document and tell cloud code how to organize the information and build out your brain, we're then going to build a self-learning skill which is going to be on-demand or could be weekly is that it's going to go through your brain and find gaps of information and research YouTube or Google or whatever source that you want to find information to fill and update those gaps. For your setup and learning skill, I do recommend you building your own because you are going to be connected to your own sources and software. But if you want to use mine as an example, just comment and brain and I'll send it to you directly.
