+> git clone --filter=blob:none --sparse https://github.com/HKUDS/OpenSpace.git
+> cd OpenSpace
+> git sparse-checkout set '/*' '!assets/'

 **Choose your path:**
 - **[Path A](#-path-a-for-your-agent)** — Plug OpenSpace into your agent
 - **[Path B](#-path-b-as-your-co-worker)** — Use OpenSpace directly as your AI co-worker
