Description
The first Claude Code source leak on public launch day (Feb 24, 2025). Developer Dave Shoemaker opened cli.mjs in the npm package and found an 18-million-character base64-encoded source map appended inline to the JavaScript bundle. Daniel Nakov extracted and republished as dnakov/claude-code the next day. Anthropic removed the source map within 2 hours, but Shoemaker recovered the pre-deletion data via Sublime Text undo history (Cmd+Z).
