This repository documents methodologies and workflows for building an AI-driven personal knowledge management system using Obsidian and Claude Code. It covers topics like treating LLM as a compiler rather than a retriever (following Karpathy’s LLM Wiki approach), using CLAUDE.md files to enable AI navigation of knowledge bases, and seven copyable workflows for practical knowledge management. The guide is presented in both PDF and Obsidian vault formats as the Chinese ‘Orange Book’ series.
