Claw-Code Hits 117K Stars as Claude Code Rewrite

Sigrid Jin's clean-room rewrite of Claude Code's agent harness — built in Rust and Python after the npm source map leak - crossed 117,000 GitHub stars and 101,000 forks in under 48 hours, reportedly the fastest repo to pass 100K stars in GitHub history. The project reimplements the orchestration layer, MCP support, plugin system, and tool wiring without copying the exposed TypeScript directly, using the oh-my-codex framework as a foundation. The disclaimers are careful: not affiliated, not endorsed, no ownership claimed over original material. Anthropic's packaging mistake effectively open-sourced the architectural blueprint for their most commercially important developer tool, and the speed at which a functional reimplementation appeared makes it clear that the competitive moat around coding agent harnesses is thinner than anyone assumed.
