Deep Agents Implementation
Core Concepts
Deep Agents provides a batteries-included agent harness built on LangGraph:
create_deep_agent: Factory function that creates a configured agent- Middleware: Injected capabilities (filesystem, todos, subagents, summarization)
- Backends: Pluggable file storage (state, filesystem, store, composite)
- Subagents: Isolated task execution via the
tasktool
The agent returned is a compiled LangGraph StateGraph, compatible with streaming, checkpointing, and LangGraph Studio.
