Sandbox your LLM coding agents on macOS so they can only touch the files they need. Useful for ai-agents and claude-code use cases.

Drop-in AGENTS.md that makes every coding agent behave like a senior engineer instead of an eager intern. Kills sycophancy, stops drive-by refactors, forces verification loops. Synthesizes Karpathy's four principles and Boris Cherny's Claude Code workflow. Works with Claude Code, Codex, Gemini CLI, Cursor, and the open standard.

The free AI already on your Mac. CLI tool, OpenAI-compatible server, and interactive chat — all on-device via Apple Intelligence. No API keys, no cloud, no downloads.

📦 A macOS utility to seamlessly migrate applications to external storage and reclaim local disk space.【一款 macOS 工具，无缝迁移应用到外部存储并自动建立链接，释放宝贵的本地空间】
