DeepAgents JS DeepAgents JS
DeepAgents JS is an opinionated, ready-to-run agent harness built on top of LangGraph that provides built-in capabilities like task planning, file system access, and sub-agent delegation. It is designed to be highly customizable, allowing developers to swap models, tools, and middleware while maintaining production-ready features like streaming and persistence.
Version 0.7 introduced a leaner base harness that reduces base input tokens by 65%, moved task planning (TodoListMiddleware) to an opt-in status, and provided improved configurability for overriding default middleware stacks.
As of
- Built-in sub-agent spawning for context isolation
- Comprehensive virtual filesystem tools (read, write, edit, grep, glob)
- Modular middleware architecture for planning and context management
- Production-ready integration with LangGraph and LangSmith
- Human-in-the-loop support for sensitive tool operations
Complex, multi-step tasks that require long-horizon planning, file interaction, or delegating sub-tasks to specialized agents.
Simple, single-turn tasks where the overhead of an agent harness (context management and sub-agent logic) is unnecessary.
