About Deep Agents

Deep Agents is a modular agent architecture in the LangChain ecosystem that combines planning, long-term filesystem-backed memory, and the ability to spawn subagents to solve complex, multi-step problems. Implemented as middleware, Deep Agents automatically attach PlanningMiddleware, FilesystemMiddleware, and SubAgentMiddleware when created via create_deep_agent, enabling structured task decomposition, persistent context storage, and delegation. The system supports human-in-the-loop workflows through LangGraph interrupts and a checkpointer/HITL middleware for tool approval, and the resulting agent is a LangGraph graph that can be interacted with via streaming, memory APIs, and studio tooling. Unique value comes from its composable middleware design which lets developers build research-grade, long-horizon agent workflows that balance automation, memory persistence, and human oversight.

Key Features

Modular Middleware Architecture: Deep Agents are constructed from discrete middleware components (PlanningMiddleware, FilesystemMiddleware, SubAgentMiddleware) enabling flexible composition and extension of agent capabilities.
Built-in Planning & Task Decomposition: Includes a write_todos tool and planning utilities that break complex objectives into discrete, trackable steps and adapt plans as new information appears.
Filesystem-backed Long-term Memory: Provides a filesystem middleware for storing contextual data and long-term memories so agents can persist state and recall past results across sessions.
Subagent Spawning and Delegation: Can spawn and manage subagents to delegate subtasks, enabling parallel or hierarchical workflows for large or multi-domain tasks.
Human-in-the-Loop Approvals: Integrates with LangGraph’s interrupt/checkpointer mechanisms and prebuilt HITL middleware to pause execution and require human approval for sensitive tool operations.
LangGraph Integration & Interactivity: Agents created with create_deep_agent are LangGraph graphs, allowing streaming, memory management, studio interaction, and parity with other LangGraph workflows.
Modular middleware architecture (PlanningMiddleware, FilesystemMiddleware, SubAgentMiddleware) automatically attached by create_deep_agent
Built-in planning and task decomposition tool (write_todos) for breaking down and tracking long-horizon tasks
