→LangChain ambassador releases open-source Deep Agents tutorial built on a three-layer architecture
Authored by LangChain ambassador Zhang Haili, the tutorial uses a three-layer architecture—Runtime (LangGraph), Framework (LangChain), and Harness (Deep Agents). Its technical core is context engineering: a virtual file system handles on-demand reads, intermediate result persistence, and partial reads of large files. The course spans 8 chapters plus 2 prep sections, covering six file tools, task planning, async parallel sub-agent delegation, and reusable Skills that work across 30+ tools including Claude Code and Cursor.
