I Tested the Fastest-Growing GitHub Repo Ever — Here Is What Claw Code Actually Does

Last week, a packaging mistake at Anthropic leaked 512,000 lines of Claude Code's source. Within 48 hours, someone rebuilt the entire agent harness from scratch. That project - Claw Code - just crossed 100,000 GitHub stars. I installed it, pointed it at three of my projects, and ran it alongside Claude Code to see what holds up. What Claw Code Actually Is Claw Code is a Python/Rust rewrite of the agent architecture behind Claude Code. It reads your codebase, plans edits, runs terminal commands, and iterates until the task is done.
