Why we included this project

Deep Agents is an opinionated agent harness for TypeScript that gives you a working agent out of the box. It bundles planning through a write_todos tool, filesystem operations for working memory, and a task tool that delegates work to sub-agents with isolated context windows. Because createDeepAgent returns a compiled LangGraph graph, you keep streaming, checkpointing, and the rest of the LangGraph runtime while swapping in your own models, tools, and system prompts. It works with any tool-calling chat model, so teams can prototype quickly and then customize toward production. The package also ships browser and Node entrypoints, which is handy if you need the same agent logic in different runtimes.
