+# Think (Experimental)
+
+Fetch https://developers.cloudflare.com/agents/api-reference/think/ for complete documentation.
+
+`@cloudflare/think` — a higher-level chat agent class that handles the `streamText` loop, tool execution, and message persistence for you. You provide `getModel()` and `getSystemPrompt()`; Think handles the rest.
+
+```bash
+npm install @cloudflare/think
+```
+
+## Minimal Agent
+
+```typescript
+import { Think } from "@cloudflare/think";
+import { createWorkersAI } from "workers-ai-provider";
+import { routeAgentRequest } from "agents";
+
+export class MyAgent extends Think<Env> {
+  getModel() {
+    return createWorkersAI({ binding: this.env.AI })("@cf/meta/llama-4-scout-17b-16e-instruct");
+  }
+
+  getSystemPrompt() {
+    return "You are a helpful assistant.";
+  }
+}
+
+export default {
+  fetch: (req, env) => routeAgentRequest(req, env)
+};
+```
+
+## Wrangler Config
+
+```jsonc
+{
+  "compatibility_flags": ["nodejs_compat", "experimental"],
+  "durable_objects": {
+    "bindings": [{ "name": "MyAgent", "class_name": "MyAgent" }]
+  },
+  "migrations": [{ "tag": "v1", "new_sqlite_classes": ["MyAgent"] }],
+  "ai": { "binding": "AI" }
+}
+```
+
+**Note:** Think requires the `experimental` compatibility flag.
+
+## Custom Tools
+
+```typescript
+import { tool } from "ai";
+import { z } from "zod";
+
+export class MyAgent extends Think<Env> {
+  getTools() {
+    return {
+      getWeather: tool({
+        description: "Get weather",
+        parameters: z.object({ city: z.string() }),
+        execute: async ({ city }) => `72°F in ${city}`
+      })
+    };
+  }
+}
+```
+
+## Lifecycle Hooks
+
+| Hook | When | Use for |
+|------|------|---------|
+| `configureSession()` | Agent starts | Set up memory, context providers |
+| `beforeTurn(ctx)` | Before each LLM call | Per-turn model/tools/system prompt; return `TurnConfig` |
+| `onChunk(chunk)` | Each streaming chunk | Progress tracking |
+| `onChatResponse(result)` | After LLM turn completes | Chaining, follow-up `saveMessages` |
+| `onChatError(error)` | On LLM error | Error handling |
+
+```typescript
+async beforeTurn(ctx: TurnContext): Promise<TurnConfig> {
+  if (ctx.continuation) {
+    return { model: cheaperModel };
+  }
+  return {};
+}
+```
+
+## Sub-Agents
+
+```typescript
+const child = this.subAgent(SpecialistAgent, "specialist-1");
+await child.chat("Analyze this data...", (chunk) => {
+  // stream callback
+});
+```
+
+## Client
+
+Same React hooks as `AIChatAgent`:
+
+```tsx
+const agent = useAgent({ agent: "MyAgent", name: "session-1" });
+const { messages, input, handleInputChange, handleSubmit } = useAgentChat({ agent });
+```
+
+## Think vs AIChatAgent
+
+| | Think | AIChatAgent |
+|-|-------|-------------|
+| `streamText` loop | Built-in | You write it |
+| Tool execution | Automatic | You wire it |
+| Customization | Override hooks | Full control in `onChatMessage` |
+| Built-in tools | Workspace, execute, browser | None |
+| Compatibility flag | Requires `experimental` | Standard |
