Important news about Claude Code. There was an unintentional leak of the entire source code. That means all runtime files, tools, internal logic—almost everything is included. The cause was a large cli.js.map file that was published with the package on npm, and this file allows the original source code to be easily reconstructed. As a result, anyone can access and explore the code. There are around 1,902 files, with many details, tools, and system components. Repository link: claude-code-source
