README
Claude Code: Source Code Analysis
**Dissecting Anthropic's AI Engineering Decisions from 510,000 Lines of Leaked Code**
Orange Book Series | April 2026 | By Huashu
About This Book
On March 31, 2026, Anthropic accidentally shipped the complete Claude Code source code inside an npm package. 1,902 TypeScript files, 510,000 lines of code, every design decision laid bare.
This book is not a source code reading journal. It dissects the **design decisions** behind Claude Code -- one of the world's most sophisticated AI coding tools. Why does search use grep instead of a vector database? Why does the memory system only store preferences, not code? Why does Auto mode run a second AI for safety reviews? Why Bun over Node.js?
Every choice has a reason. Those reasons are more valuable than the code itself, because they are transferable.
