LangChain just officially open-sourced an out-of-the-box agent harness—Deep Agent Set it up and it can run long tasks, multi-step work, and easily replace any component without forking. GitHub 23701 stars, from LangChain official (langchain-ai). GitHub: https://github.com/langchain-ai/deepagents… Opinionated by design: Comes pre-configured with a full suite for long tasks and multi-step workflows—sub-agents with isolated context for delegating subtasks Pluggable file system (local/sandbox/remote backend swap freely) Context management (auto-summarize long threads, offload tool outputs to disk) Shell access Cross-session persistent memory Human-in-the-loop approval for tool calls, plus on-demand loading of Skills, connect any MCP server as a tool. Model freedom: fully flexible—OpenAI, Anthropic, local open-source models, any model that supports tool calling works. Under the hood, it uses LangGraph: streaming, persistence, checkpoints all included, plus LangSmith for tracing, evaluation, deployment—ready for production use. README explicitly says inspiration from Claude Code—aiming to extract its universal essence and push the idea further. Deployment is minimal: `uv add deepagents`, three lines of `create_deep_agent(model=..., tools=..., system_prompt=...)` and you're up and running. A real agent, not a toy demo—production infrastructure ready to connect.
