About this pageAI generated

This page reports on a security incident involving Anthropic's AI coding assistant "Claude Code." A source map file was accidentally included in an npm package (version 2.1.88), exposing TypeScript source code. Anthropic stated this was a human error in packaging, not a security breach, and confirmed no customer data leaked. A security researcher raised the issue on X, after which the code spread on GitHub. Developers have begun analyzing the code and attempting reimplementation from scratch.
