Claude Code Source Code LEAK (How to build it yourself)
Anthropic accidentally leaked Claude Code's entire source code — over 600,000 lines of TypeScript — through a single misincluded map file. Within hours, tens of thousands of GitHub forks spread it across the internet. The leak exposed Anthropic's hidden development roadmap, including autonomous background agents, persistent memory, multi-agent orchestration, and a surprisingly elaborate virtual pet system. The AI era just got a lot more transparent. And rebuild yourself.
