TITLE: Anthropic Leaked Cloud Code Source Code (NPM Source Map Security Fail) DESCRIPTION: Breaking news in the AI dev world: Anthropic accidentally leaked the complete source code for their Cloud Code agent, and it happened through a classic build configuration mistake that could affect anyone shipping JavaScript or TypeScript. In this video, we break down exactly how source maps work, why they contain your raw source code as strings, and how Anthropic published theirs to the public NPM registry. We also cover the community response—specifically how one developer already reverse-engineered the entire codebase into Rust. Whether you're a senior engineer or just getting started with web development, this is a critical security framework to understand: your build artifacts are part of your attack surface. One missing flag in your build pipeline can expose your entire intellectual property.
