Overview
- Anthropic released a macOS-only Computer Use CLI for Claude Code on Tuesday, showing in a demo that it can launch apps, reproduce bugs, apply fixes, and run tests without leaving the terminal.
- The tool adds layered safeguards, including a single-session lock, per‑app approval prompts, tiered permissions that limit what tools can change, instant stop with Esc or Ctrl+C, and a rule that hides terminal text from screenshots.
- Separate coverage reports that Claude Code’s internals were exposed through an npm source‑map file, with one account citing about 1,900 files and roughly 512,000 lines of TypeScript.
- Another report describes a reconstructed repo with 4,756 files and recovered developer comments, and coverage stresses this was not an open‑source release but likely an accidental source‑map exposure or reverse‑engineering.
- Developers quickly mirrored the files and shared analyses on GitHub and X, a rush that could speed scrutiny of Claude Code’s design and inspire copycat tooling.
