 Using an LLM to call tools in a loop is the simplest form of an agent. This architecture, however, can yield agents that are "shallow" and fail to plan and act over longer, more complex tasks. Applications like "Deep Research", "Manus", and "Claude Code" have gotten around this limitation by implementing a combination of four things: a planning tool, sub agents, access to a file system, and a detailed prompt.

 ## Installation
 
 ```bash
-yarn add deepagents
+npm install deepagents
+```
+
+## Usage
+
+You can find a full example for how to use this agent in [research-agent.ts](/examples/research/research-agent.ts):
+
+```ts
+const agent = createDeepAgent({
+  model: new ChatAnthropic({
+    model: "claude-3-5-sonnet-20240620",
+    temperature: 0,
+  }),
+  tools: [internetSearch],
+  instructions: researchInstructions,
+  subagents: [critiqueSubAgent, researchSubAgent],
+});
+
+// Invoke the agent
+const result = await agent.invoke({
+    messages: [{ role: "user", content: "what is langgraph?" }],
+}, { recursionLimit: 1000 });
+
+console.log("🎉 Finished!")
+console.log(`\n\nAgent ToDo List:\n${result.todos.map((todo) => ` - ${todo.content} (${todo.status})`).join("\n")}`);
+console.log(`\n\nAgent Files:\n${Object.entries(result.files).map(([key, value]) => ` - ${key}: ${value}`).join("\n")}`);
+```
+
+Which will return:
+
+```
+🎉 Finished!
+
+Agent ToDo List:
+ - Research LangGraph using the research-agent (completed)
+ - Write a comprehensive report on LangGraph (completed)
+ - Review and critique the report using the critique-agent (completed)
+ - Make necessary revisions to the report (completed)
+
+Agent Files:
+ - /question.txt: What is LangGraph?
+ - /final_report.md: # What is LangGraph? ...
 ```

+This tool is very helpful for planning complex objectives, and for breaking down these larger complex objectives into smaller steps.
+
+It is critical that you mark todos as completed as soon as you are done with a step. Do not batch up multiple steps before marking them as completed.
+For simple objectives that only require a few steps, it is better to just complete the objective directly and NOT use this tool.
+Writing todos takes time and tokens, use it when it is helpful for managing complex many-step problems! But not for simple few-step requests.
