Anthropic's Claude Code CLI had its full TypeScript source exposed after a source map file was accidentally included in v2.1.88 of its npm package. The 512,000-line codebase was archived to GitHub within hours. Anthropic called it a packaging error caused by human error. The leak revealed unreleased features, internal model codenames, and multi-agent orchestration architecture. By Steef-Jan Wiggers
