Anthropic's Claude Code source leaked

The entire source code for Anthropic's Claude Code command line interface application has been leaked due to a packaging error in a recent npm release. This leak exposes nearly 2,000 TypeScript files and over 512,000 lines of code, providing competitors and developers with a detailed blueprint of the application's architecture. While Anthropic stated no customer data was compromised and attributed the leak to human error, the exposed code offers valuable insights into the AI tool's inner workings, potentially accelerating development of competing products and revealing security vulnerabilities. The company is implementing measures to prevent future occurrences.
