AgentCraft is a tool that runs Claude agents inside a Minecraft environment where you can watch them work on your code in real time. You give them a goal, they plan tasks, write code in isolated git branches, and ask you for decisions when needed — nothing merges without your approval.

• Agents work in their own git worktrees on isolated branches; your main checkout is never touched, and merges only happen when you explicitly approve them
• The interface visualizes agent work through a pixelated Minecraft studio where agents walk to desks, show live code changes on monitors, and come find you with questions
• A real test run on a sample repo landed six features with passing tests, handling merge conflicts, permission prompts, and a Foreman restart — all driven through the game interface
• Small goals cost $2-10 in Claude API usage; you can try it free with a simulated team first

Open Executive is an open-source system that uses Claude to simulate a cohesive executive team—eight specialized AI agents (CFO, CSO, CMO, etc.) that maintain context across sessions and proactively surface follow-ups. It's designed to run locally or on Fly.io with integrations for Slack, Discord, email, and other platforms.

• Eight specialist agents route through a single orchestrator to synthesize responses in one consistent executive voice, with built-in MBA knowledge layered alongside your uploaded company documents via RAG.
• Episodic memory in SQLite tracks past decisions and initiatives across sessions, and a scheduler proactively surfaces due actions—but the API must run single-instance only to avoid double-firing scheduled tasks.
• Deploys to Fly.io with separate dev and qa environments, supports document upload (pitch decks, financials, strategy docs), and offers multiple chat interfaces (web UI, Slack, Discord, email, Telegram, CLI).

Anthropic released a two-hour course led by the engineer behind Claude Code that walks you through building self-managing Claude agents. It covers terminal integration, file-system memory, hallucination-blocking hooks, and scaling to large codebases. Whether you’re a beginner or advanced user, you’ll finish ready to use Claude professionally.

• Anthropic released a free two-hour course on building Claude agents, led by the engineer who writes Claude Code
• Covers terminal integration, file-system-based memory, and hooks designed to catch and block hallucinations
• Includes guidance on scaling agents to large codebases via isolated environments and multi-file task orchestration
• Shows real failure examples (missing dependencies, misread logs) and how to harden pipelines against them
