Claude Code leak exposes Anthropic internals

The interesting part here is not just that source code leaked; it’s that the leak gives a rare look at how a production-grade terminal agent is assembled under the hood.

• –This is best read as a security incident and an architecture reveal, not a product launch.
• –The stack details suggest a fairly modern CLI implementation: Bun for runtime performance, React + Ink for terminal rendering, and TypeScript for the core logic.
• –The repo likely gives competitors and tinkerers a useful map of Claude Code’s internal workflow boundaries, especially around file edits, command execution, and git integration.
• –For developers, the takeaway is that the “magic” of these agents is increasingly in orchestration and UX composition, not just model calls.
