Open-Source Minecraft Harness Lets Claude Agents Code in Parallel Worktrees

AgentCraft, an open-source Minecraft mod released this month, brings multi-agent AI coding into an immersive, walkable studio environment where teams of Claude agents plan, build, and collaborate in isolated git worktrees. Rather than managing agents through terminal interfaces or chat windows, developers can now observe their Claude-powered team operating in real time within a 3D Minecraft space—a lead planner agent reads the repository structure and breaks work into tasks, while worker agents sit at desks, execute code changes in parallel worktrees, and physically approach the player when they need human input or approval.
