ENTIRE CLAUDE CODE CLI SOURCE CODE LEAKS THANKS TO EXPOSED MAP FILE

Summary from the TLDR newsletter

Anthropic recently published a version of the Claude Code npm package that included a source map file that could be used to access the entirety of Claude Code's source code. More than 512,000 lines of code were leaked on a public GitHub repository, which has since been forked tens of thousands of times. Developers are already analyzing the code to find out how Claude Code works. Anthropic has publicly acknowledged the mistake.
