 ## Sandboxing
 
-### macOS Seatbelt
-
-On macOS, `qwen` uses Seatbelt (`sandbox-exec`) under a `permissive-open` profile (see `packages/cli/src/utils/sandbox-macos-permissive-open.sb`) that restricts writes to the project folder but otherwise allows all other operations and outbound network traffic ("open") by default. You can switch to a `restrictive-closed` profile (see `packages/cli/src/utils/sandbox-macos-restrictive-closed.sb`) that declines all operations and outbound network traffic ("closed") by default by setting `SEATBELT_PROFILE=restrictive-closed` in your environment or `.env` file. Available built-in profiles are `{permissive,restrictive}-{open,closed,proxied}` (see below for proxied networking). You can also switch to a custom profile `SEATBELT_PROFILE=<profile>` if you also create a file `.qwen/sandbox-macos-<profile>.sb` under your project settings directory `.qwen`.
-
-### Container-based Sandboxing (All Platforms)
-
-For stronger container-based sandboxing on macOS or other platforms, you can set `GEMINI_SANDBOX=true|docker|podman|<command>` in your environment or `.env` file. The specified command (or if `true` then either `docker` or `podman`) must be installed on the host machine. Once enabled, `npm run build:all` will build a minimal container ("sandbox") image and `npm start` will launch inside a fresh instance of that container. The first build can take 20-30s (mostly due to downloading of the base image) but after that both build and start overhead should be minimal. Default builds (`npm run build`) will not rebuild the sandbox.
-
-Container-based sandboxing mounts the project directory (and system temp directory) with read-write access and is started/stopped/removed automatically as you start/stop Gemini CLI. Files created within the sandbox should be automatically mapped to your user/group on host machine. You can easily specify additional mounts, ports, or environment variables by setting `SANDBOX_{MOUNTS,PORTS,ENV}` as needed. You can also fully customize the sandbox for your projects by creating the files `.qwen/sandbox.Dockerfile` and/or `.qwen/sandbox.bashrc` under your project settings directory (`.qwen`) and running `qwen` with `BUILD_SANDBOX=1` to trigger building of your custom sandbox.
-
-#### Proxied Networking
-
-All sandboxing methods, including macOS Seatbelt using `*-proxied` profiles, support restricting outbound network traffic through a custom proxy server that can be specified as `GEMINI_SANDBOX_PROXY_COMMAND=<command>`, where `<command>` must start a proxy server that listens on `:::8877` for relevant requests. See `docs/examples/proxy-script.md` for a minimal proxy that only allows `HTTPS` connections to `example.com:443` (e.g. `curl https://example.com`) and declines all other requests. The proxy is started and stopped automatically alongside the sandbox.

-## VS Code Extension
-
-In addition to the CLI tool, Qwen Code also provides a **VS Code extension** that brings AI-powered coding assistance directly into your editor with features like file system operations, native diffing, interactive chat, and more.
-
-> 📦 The extension is currently in development. For installation, features, and development guide, see the [VS Code Extension README](./packages/vscode-ide-companion/README.md).
-
 ## Quick Start
 
 ```bash
-# Start Qwen Code
+# Start Qwen Code (interactive)
 qwen
 
-# Example commands
-> Explain this codebase structure
-> Help me refactor this function
-> Generate unit tests for this module
+# Then, in the session:
+/help
+/auth
 ```
 
-### Session Management
+On first use, you'll be prompted to sign in. You can run `/auth` anytime to switch authentication methods.
 
-Control your token usage with configurable session limits to optimize costs and performance.
+Example prompts:
 
-#### Configure Session Token Limit
-
-Create or edit `.qwen/settings.json` in your home directory:
-
-```json
-{
-  "sessionTokenLimit": 32000
-}
+```text
+What does this project do?
+Explain the codebase structure.
+Help me refactor this function.
+Generate unit tests for this module.
 ```
 
-#### Session Commands
-
-- **`/compress`** - Compress conversation history to continue within token limits
-- **`/clear`** - Clear all conversation history and start fresh
-- **`/stats`** - Check current token usage and limits
-
-> 📝 **Note**: Session token limit applies to a single conversation, not cumulative API calls.
-
-### Vision Model Configuration
-
-Qwen Code includes intelligent vision model auto-switching that detects images in your input and can automatically switch to vision-capable models for multimodal analysis. **This feature is enabled by default** - when you include images in your queries, you'll see a dialog asking how you'd like to handle the vision model switch.
-
-#### Skip the Switch Dialog (Optional)
-
-If you don't want to see the interactive dialog each time, configure the default behavior in your `.qwen/settings.json`:
-
-```json
-{
-  "experimental": {
-    "vlmSwitchMode": "once"
-  }
-}
-```
-
-**Available modes:**
-
-- **`"once"`** - Switch to vision model for this query only, then revert
-- **`"session"`** - Switch to vision model for the entire session
-- **`"persist"`** - Continue with current model (no switching)
-- **Not set** - Show interactive dialog each time (default)
-
-#### Command Line Override
-
-You can also set the behavior via command line:
-
-```bash
-# Switch once per query
-qwen --vlm-switch-mode once
-
-# Switch for entire session
-qwen --vlm-switch-mode session
-
-# Never switch automatically
-qwen --vlm-switch-mode persist
-```
-
-#### Disable Vision Models (Optional)
-
-To completely disable vision model support, add to your `.qwen/settings.json`:
-
-```json
-{
-  "experimental": {
-    "visionModelPreview": false
-  }
-}
-```
-
-> 💡 **Tip**: In YOLO mode (`--yolo`), vision switching happens automatically without prompts when images are detected.
-
-### Authorization
-
-Choose your preferred authentication method based on your needs:
-
-#### 1. Qwen OAuth (🚀 Recommended - Start in 30 seconds)
-
-The easiest way to get started - completely free with generous quotas:
-
-```bash
-# Just run this command and follow the browser authentication
-qwen
-```
-
-**What happens:**
-
-1. **Instant Setup**: CLI opens your browser automatically
-2. **One-Click Login**: Authenticate with your qwen.ai account
-3. **Automatic Management**: Credentials cached locally for future use
-4. **No Configuration**: Zero setup required - just start coding!
-
-**Free Tier Benefits:**
-
-- ✅ **2,000 requests/day** (no token counting needed)
-- ✅ **60 requests/minute** rate limit
-- ✅ **Automatic credential refresh**
-- ✅ **Zero cost** for individual users
-- ℹ️ **Note**: Model fallback may occur to maintain service quality
-
-#### 2. OpenAI-Compatible API
-
-Use API keys for OpenAI or other compatible providers:
-
-**Configuration Methods:**
-
-1. **Environment Variables**
-
-   ```bash
-   export OPENAI_API_KEY="your_api_key_here"
-   export OPENAI_BASE_URL="your_api_endpoint"
-   export OPENAI_MODEL="your_model_choice"
-   ```
-
-2. **Project `.env` File**
-   Create a `.env` file in your project root:
-   ```env
-   OPENAI_API_KEY=your_api_key_here
-   OPENAI_BASE_URL=your_api_endpoint
-   OPENAI_MODEL=your_model_choice
-   ```

-**Option 2: OpenRouter (Free Tier Available)** ([Apply for API Key](https://openrouter.ai/))
+Choose **Qwen OAuth** and complete the browser flow. Your credentials are cached locally so you usually won't need to log in again.
+
+#### OpenAI-compatible API (API key)
+
+Environment variables (recommended for CI / headless environments):
 
 ```bash
-export OPENAI_API_KEY="your_api_key_here"
-export OPENAI_BASE_URL="https://openrouter.ai/api/v1"
-export OPENAI_MODEL="qwen/qwen3-coder:free"
+export OPENAI_API_KEY="your-api-key-here"
+export OPENAI_BASE_URL="https://api.openai.com/v1"  # optional
+export OPENAI_MODEL="gpt-4o"                        # optional
 ```

-## Usage Examples
+## Usage
 
-### 🔍 Explore Codebases
+As an open-source terminal agent, you can use Qwen Code in four primary ways:
+
+1. Interactive mode (terminal UI)
+2. Headless mode (scripts, CI)
+3. IDE integration (VS Code, Zed)
+4. TypeScript SDK
+
+#### Interactive mode
 
 ```bash
 cd your-project/
 qwen
-
-# Architecture analysis
-> Describe the main pieces of this system's architecture
-> What are the key dependencies and how do they interact?
-> Find all API endpoints and their authentication methods
 ```
 
-### 💻 Code Development
+Run `qwen` in your project folder to launch the interactive terminal UI. Use `@` to reference local files (for example `@src/main.ts`).
+
+#### Headless mode
 
 ```bash
-# Refactoring
-> Refactor this function to improve readability and performance
-> Convert this class to use dependency injection
-> Split this large module into smaller, focused components
-
-# Code generation
-> Create a REST API endpoint for user management
-> Generate unit tests for the authentication module
-> Add error handling to all database operations
+cd your-project/
+qwen -p "your question"
 ```
 
-### 🔄 Automate Workflows
+Use `-p` to run Qwen Code without the interactive UI—ideal for scripts, automation, and CI/CD. Learn more: [Headless mode](https://qwenlm.github.io/qwen-code-docs/en/users/features/headless).
 
-```bash
-# Git automation
-> Analyze git commits from the last 7 days, grouped by feature
-> Create a changelog from recent commits
-> Find all TODO comments and create GitHub issues
+#### IDE integration
 
-# File operations
-> Convert all images in this directory to PNG format
-> Rename all test files to follow the *.test.ts pattern
-> Find and remove all console.log statements
-```
+Use Qwen Code inside your editor (VS Code and Zed):

+# Qwen Code Java SDK
+
+## Project Overview
+
+The Qwen Code Java SDK is a minimum experimental SDK for programmatic access to Qwen Code functionality. It provides a Java interface to interact with the Qwen Code CLI, allowing developers to integrate Qwen Code capabilities into their Java applications.
+
+The project is structured as a Maven-based Java library with the following key characteristics:
+
+- **Group ID**: com.alibaba
+- **Artifact ID**: qwencode-sdk-java
+- **Version**: 0.0.1
+- **Packaging**: JAR
+- **Java Version**: 1.8+ (source and target)
+
+## Architecture
+
+The SDK follows a layered architecture:
+
+- **CLI Layer**: Provides the main entry point through `QwenCodeCli` class
+- **Session Layer**: Manages communication sessions with the Qwen Code CLI
+- **Transport Layer**: Handles communication between the SDK and CLI process
+- **Protocol Layer**: Defines data structures for communication
+- **Utils**: Common utilities for concurrent execution and timeout handling
+
+## Key Components
+
+### Main Classes
+
+- `QwenCodeCli`: Main entry point with static methods for simple queries
+- `Session`: Manages communication sessions with the CLI
+- `Transport`: Abstracts the communication mechanism (currently using process transport)
+- `ProcessTransport`: Implementation that communicates via process execution
+
+### Dependencies
+
+- **Logging**: ch.qos.logback:logback-classic
+- **Utilities**: org.apache.commons:commons-lang3
+- **JSON Processing**: com.alibaba.fastjson2:fastjson2
+- **Testing**: JUnit 5 (org.junit.jupiter:junit-jupiter)
+
+## Building and Running
+
+### Prerequisites
+
+- Java 8 or higher
+- Apache Maven 3.6.0 or higher
+
+### Build Commands
+
+```bash
+# Compile the project
+mvn compile
+
+# Run tests
+mvn test
+
+# Package the JAR
+mvn package
+
+# Install to local repository
+mvn install
+
+# Run checkstyle verification
+mvn checkstyle:check
+```
+
+### Testing
+
+The project includes basic unit tests using JUnit 5. The main test class `QwenCodeCliTest` demonstrates how to use the SDK to make simple queries to the Qwen Code CLI.
+
+### Code Quality
+
+The project uses Checkstyle for code formatting and style enforcement. The configuration is defined in `checkstyle.xml` and includes rules for:
+
+- Whitespace and indentation
+- Naming conventions
+- Import ordering
+- Code structure
+
+## Development Conventions
+
+### Coding Standards
+
+- Java 8 language features are supported
+- Follow standard Java naming conventions
+- Use UTF-8 encoding for source files
+- Line endings should be LF (Unix-style)
+- No trailing whitespace allowed
+- Use 8-space indentation for line wrapping
+
+### Testing Practices
+
+- Write unit tests using JUnit 5
+- Test classes should be in the `src/test/java` directory
+- Follow the naming convention `*Test.java` for test classes
+- Use appropriate assertions to validate functionality
+
+### Documentation
+
+- API documentation should follow JavaDoc conventions
+- Update README files when adding new features
+- Include examples in documentation
+
+## API Reference
+
+### QwenCodeCli Class
+
+The main class provides two primary methods:
+
+- `simpleQuery(String prompt)`: Synchronous method that returns a list of responses
+- `simpleQuery(String prompt, Consumer<String> messageConsumer)`: Asynchronous method that streams responses to a consumer
+
+### Permission Modes
+
+The SDK supports different permission modes for controlling tool execution:
+
+- **`default`**: Write tools are denied unless approved via `canUseTool` callback or in `allowedTools`. Read-only tools execute without confirmation.
+- **`plan`**: Blocks all write tools, instructing AI to present a plan first.
+- **`auto-edit`**: Auto-approve edit tools (edit, write_file) while other tools require confirmation.
+- **`yolo`**: All tools execute automatically without confirmation.
+
+## Usage Example
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import java.util.List;
+
+public class Example {
+    public static void main(String[] args) {
+        List<String> result = QwenCodeCli.simpleQuery("hello world");
+        result.forEach(System.out::println);
+    }

+# Qwen Code Java SDK
+
+A minimum experimental Java SDK for programmatic access to Qwen Code functionality. This SDK provides a Java interface to interact with the Qwen Code CLI, allowing developers to integrate Qwen Code capabilities into their Java applications.
+
+Feel free to submit a feature request/issue/PR.
+
+## Installation
+
+Add the following dependency to your Maven `pom.xml`:
+
+```xml
+<dependency>
+    <groupId>com.alibaba</groupId>
+    <artifactId>qwencode-sdk-java</artifactId>
+    <version>0.0.1</version>
+</dependency>
+```
+
+Or if using Gradle, add to your `build.gradle`:
+
+```gradle
+implementation 'com.alibaba:qwencode-sdk-java:0.0.1'
+```
+
+## Requirements
+
+- Java >= 1.8
+- Maven >= 3.6.0 (for building from source)
+- Qwen Code CLI: The SDK communicates with the Qwen Code CLI executable. By default, the SDK looks for a `qwen` command in the system PATH.
+
+## Quick Start
+
+The simplest way to use the SDK is through the `QwenCodeCli.simpleQuery()` method:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import java.util.List;
+
+public class Example {
+    public static void main(String[] args) {
+        List<String> result = QwenCodeCli.simpleQuery("hello world");
+        result.forEach(System.out::println);
+    }
+}
+```
+
+For more advanced usage with streaming responses:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import java.util.function.Consumer;
+
+public class StreamingExample {
+    public static void main(String[] args) {
+        QwenCodeCli.simpleQuery("hello world", (String message) -> {
+            System.out.println("Received: " + message);
+        });
+    }
+}
+```
+
+For session-based usage with custom event handling:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import com.alibaba.qwen.code.cli.protocol.message.assistant.SDKAssistantMessage;
+import com.alibaba.qwen.code.cli.utils.Timeout;
+import java.util.concurrent.TimeUnit;
+
+public class SessionExample {
+    public static void main(String[] args) {
+        try (Session session = QwenCodeCli.newSession()) {
+            SessionEventSimpleConsumers eventConsumers = new SessionEventSimpleConsumers() {
+                @Override
+                public void onAssistantMessage(Session session, SDKAssistantMessage assistantMessage) {
+                    String message = assistantMessage.getMessage().getContent().stream()
+                        .findFirst()
+                        .map(content -> content.getText())
+                        .orElse("");
+                    System.out.println("Assistant: " + message);
+                }
+            }.setDefaultEventTimeout(new Timeout(60L, TimeUnit.SECONDS));
+
+            session.sendPrompt("hello world", eventConsumers);
+        } catch (Exception e) {
+            e.printStackTrace();
+        }
+    }
+}
+```
+
+## Architecture
+
+The Qwen Code Java SDK follows a layered architecture that abstracts the communication with the Qwen Code CLI:
+
+### Layered Architecture
+
+- **API Layer**: Provides the main entry points through `QwenCodeCli` class with simple static methods for basic usage
+- **Session Layer**: Manages communication sessions with the Qwen Code CLI through the `Session` class
+- **Transport Layer**: Handles the communication mechanism between the SDK and CLI process (currently using process transport via `ProcessTransport`)
+- **Protocol Layer**: Defines data structures for communication based on the CLI protocol
+- **Utils**: Common utilities for concurrent execution, timeout handling, and error management
+
+### Core Classes and Their Relationships
+
+- `QwenCodeCli`: The main entry point that provides static methods (`simpleQuery`) which internally create and manage `Session` instances
+- `Session`: Manages the lifecycle of a communication session with the CLI, including initialization, prompt sending, and cleanup
+- `Transport`: Abstracts the communication mechanism (currently implemented by `ProcessTransport`)
+- `ProcessTransport`: Implementation that communicates with the CLI via process execution, using `TransportOptions` for configuration
+- `TransportOptions`: Configuration class that defines how the transport layer should interact with the CLI (path to executable, working directory, model, permission mode, etc.)
+- `SessionEventSimpleConsumers`: Event handler interface for processing responses from the CLI, allowing custom handling of assistant messages and other events
+- `PermissionMode`: Enum that defines different permission modes for controlling tool execution (default, plan, auto-edit, yolo)
+
+The architecture allows for both simple usage through static methods in `QwenCodeCli` and more advanced usage through direct `Session` management with custom event handlers and transport options.
+
+## Usage
+
+### Session Event Consumers
+
+The SDK allows you to customize how events from the CLI are handled using event consumers. The `SessionEventConsumers` interface provides callbacks for different types of messages during a session:
+
+- `onSystemMessage`: Handles system messages from the CLI (receives Session and SDKSystemMessage)
+- `onResultMessage`: Handles result messages from the CLI (receives Session and SDKResultMessage)
+- `onAssistantMessage`: Handles assistant messages (AI responses) (receives Session and SDKAssistantMessage)
+- `onPartialAssistantMessage`: Handles partial assistant messages during streaming (receives Session and SDKPartialAssistantMessage)
+- `onUserMessage`: Handles user messages (receives Session and SDKUserMessage)
+- `onOtherMessage`: Handles other types of messages (receives Session and String message)
+- `onControlResponse`: Handles control responses (receives Session and CLIControlResponse)
+- `onControlRequest`: Handles control requests (receives Session and CLIControlRequest, returns CLIControlResponse)
+- `onPermissionRequest`: Handles permission requests (receives Session and CLIControlRequest<CLIControlPermissionRequest>, returns Behavior)
+- `onAssistantMessageIncludePartial`: Handles assistant messages including partial content (specific to SessionEventSimpleConsumers, called by both onAssistantMessage and onPartialAssistantMessage) (receives Session, List<AssistantContent>, and AssistantMessageOutputType)
+
+Event processing is subject to the timeout settings configured in `TransportOptions` and `SessionEventConsumers`. For detailed timeout configuration options, see the "Timeout" section above.

+```
+
+### Permission Modes
+
+The SDK supports different permission modes for controlling tool execution:
+
+- **`default`**: Write tools are denied unless approved via `canUseTool` callback or in `allowedTools`. Read-only tools execute without confirmation.
+- **`plan`**: Blocks all write tools, instructing AI to present a plan first.
+- **`auto-edit`**: Auto-approve edit tools (edit, write_file) while other tools require confirmation.
+- **`yolo`**: All tools execute automatically without confirmation.
+
+To set a permission mode:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.transport.TransportOptions;
+import com.alibaba.qwen.code.cli.protocol.data.PermissionMode;
+
+public class PermissionModeExample {
+    public static void main(String[] args) {
+        Session session = QwenCodeCli.newSession(new TransportOptions().setPermissionMode(PermissionMode.YOLO));
+        session.setPermissionMode(PermissionMode.PLAN);
+    }
+}
+```
+
+### Session Control
+
+The SDK provides fine-grained control over session lifecycle and behavior:
+
+- **Session creation**: Use `QwenCodeCli.newSession()` to create a new session with custom options
+- **Session management**: The `Session` class provides methods to send prompts, handle responses, and manage session state
+- **Session cleanup**: Always close sessions using `session.close()` to properly terminate the CLI process
+- **Session resumption**: Use `setResumeSessionId()` in `TransportOptions` to resume a previous session
+- **Session interruption**: Use `session.interrupt()` to interrupt a currently running prompt
+- **Dynamic model switching**: Use `session.setModel()` to change the model during a session
+- **Dynamic permission mode switching**: Use `session.setPermissionMode()` to change the permission mode during a session
+
+Example of session control:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import com.alibaba.qwen.code.cli.transport.TransportOptions;
+import com.alibaba.qwen.code.cli.protocol.data.PermissionMode;
+import java.util.List;
+
+public class SessionControlExample {
+    public static void main(String[] args) {
+        TransportOptions options = new TransportOptions()
+            .setModel("qwen-max")
+            .setPermissionMode(PermissionMode.AUTO_EDIT);
+
+        try (Session session = QwenCodeCli.newSession(options)) {
+            // Use the session with default event consumers
+            List<String> result = session.sendPrompt("Explain how to use the SDK", new SessionEventSimpleConsumers());
+            result.forEach(System.out::println);
+        } // Session automatically closes when exiting try-with-resources
+    }
+}
+```
+
+#### Interrupt Function
+
+The `interrupt()` function allows you to interrupt a currently running prompt. This is useful when you need to stop a long-running operation without closing the entire session:
+
+- **Method signature**: `public Optional<Boolean> interrupt() throws SessionControlException`
+- **Purpose**: Interrupts the current prompt processing without closing the session
+- **Return value**: An `Optional<Boolean>` that indicates whether the interrupt was successful (true if successful, empty if the interrupt was sent asynchronously)
+
+Example of interrupting a running prompt:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import com.alibaba.qwen.code.cli.protocol.message.assistant.SDKAssistantMessage;
+import com.alibaba.qwen.code.cli.session.exception.SessionControlException;
+import java.util.Optional;
+
+public class InterruptExample {
+    public static void main(String[] args) {
+        try (Session session = QwenCodeCli.newSession()) {
+            session.sendPrompt("Analyze this large codebase...", new SessionEventSimpleConsumers() {
+                @Override
+                public void onAssistantMessage(Session session, SDKAssistantMessage assistantMessage) {
+                    System.out.println("Received: " + assistantMessage.getMessage().getContent().stream()
+                        .findFirst()
+                        .map(content -> content.getText())
+                        .orElse(""));
+
+                    // Interrupt the session after receiving the first message
+                    try {
+                        Optional<Boolean> interruptResult = session.interrupt();
+                        System.out.println(interruptResult.map(s -> s ? "Interrupt successful" : "Interrupt error")
+                                .orElse("Interrupt unknown"));
+                    } catch (SessionControlException e) {
+                        System.err.println("Interrupt error: " + e.getMessage());
+                    }
+                }
+            });
+        }
+    }
+}
+```
+
+#### Set Model Function
+
+The `setModel()` function allows you to dynamically change the AI model during an active session. This is useful when you want to switch between different models (e.g., from a faster model for simple queries to a more powerful model for complex analysis) without creating a new session:
+
+- **Method signature**: `public Optional<Boolean> setModel(String modelName) throws SessionControlException`
+- **Purpose**: Changes the AI model being used for the current and subsequent prompts in the session
+- **Parameters**: `modelName` - the name of the model to switch to (e.g., "qwen-max", "qwen-plus", etc.)
+- **Return value**: An `Optional<Boolean>` that indicates whether the model change was successful (true if successful, empty if the request was sent asynchronously)
+
+Example of changing the model during a session:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import java.util.Optional;
+
+public class SetModelExample {
+    public static void main(String[] args) {
+        try (Session session = QwenCodeCli.newSession()) {
+            // Switch to a specific model
+            Optional<Boolean> modelChangeResult = session.setModel("qwen3-coder-flash");
+            System.out.println(modelChangeResult.map(s -> s ? "setModel success" : "setModel error")
+                    .orElse("setModel unknown"));
+
+            // Use the model for a prompt
+            session.sendPrompt("hello world", new SessionEventSimpleConsumers());
+
+            // Switch to another model
+            Optional<Boolean> modelChangeResult2 = session.setModel("qwen3-coder-plus");
+            System.out.println(modelChangeResult2.map(s -> s ? "setModel success" : "setModel error")
+                    .orElse("setModel unknown"));
+
+            // Use the new model for another prompt
+            session.sendPrompt("list files in the current directory", new SessionEventSimpleConsumers());
+        }
+    }
+}
+```
+
+#### Set Permission Mode Function
+
+The `setPermissionMode()` function allows you to dynamically change the permission mode during an active session. This is useful when you want to adjust the level of access granted to tools (e.g., switching from a restrictive mode to allow more operations) without creating a new session:
+
+- **Method signature**: `public Optional<Boolean> setPermissionMode(PermissionMode permissionMode) throws SessionControlException`
+- **Purpose**: Changes the permission mode governing tool execution for the current and subsequent prompts in the session
+- **Parameters**: `permissionMode` - the permission mode to switch to (e.g., `PermissionMode.DEFAULT`, `PermissionMode.PLAN`, `PermissionMode.AUTO_EDIT`, `PermissionMode.YOLO`)
+- **Return value**: An `Optional<Boolean>` that indicates whether the permission mode change was successful (true if successful, empty if the request was sent asynchronously)
+
+Example of changing the permission mode during a session:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import com.alibaba.qwen.code.cli.protocol.data.PermissionMode;
+import java.util.Optional;
+
+public class SetPermissionModeExample {
+    public static void main(String[] args) {
+        try (Session session = QwenCodeCli.newSession()) {
+            // Switch to a permissive mode
+            Optional<Boolean> permissionChangeResult = session.setPermissionMode(PermissionMode.YOLO);
+            System.out.println(permissionChangeResult.map(s -> s ? "setPermissionMode success" : "setPermissionMode error")
+                    .orElse("setPermissionMode unknown"));
+
+            // Use the session with the new permission mode
+            session.sendPrompt("in the dir src/test/temp/, create file empty file test.touch", new SessionEventSimpleConsumers());
+
+            // Switch to another permission mode
+            Optional<Boolean> permissionChangeResult2 = session.setPermissionMode(PermissionMode.PLAN);
+            System.out.println(permissionChangeResult2.map(s -> s ? "setPermissionMode success" : "setPermissionMode error")
+                    .orElse("setPermissionMode unknown"));
+
+            // Use the session with the new permission mode
+            session.sendPrompt("rename test.touch to test_rename.touch", new SessionEventSimpleConsumers());
+        }
+    }
+}
+```
+
+### Timeout Configuration
+
+The timeout configuration allows you to control how long the SDK waits for responses from the CLI before timing out. There are two levels of timeout configuration:
+
+- **Transport-level timeouts**: Configured via `TransportOptions`
+  - `turnTimeout`: Time to wait for a complete turn of conversation (default: 60 seconds)
+  - `messageTimeout`: Time to wait for individual messages within a turn (default: 60 seconds)
+
+- **Event-level timeouts**: Configured via `SessionEventConsumers` interface with callback methods for specific message types:
+  - `onSystemMessageTimeout`: Timeout for processing system messages
+  - `onResultMessageTimeout`: Timeout for processing result messages
+  - `onAssistantMessageTimeout`: Timeout for processing assistant messages
+  - `onPartialAssistantMessageTimeout`: Timeout for processing partial assistant messages
+  - `onUserMessageTimeout`: Timeout for processing user messages
+  - `onOtherMessageTimeout`: Timeout for processing other types of messages
+  - `onControlResponseTimeout`: Timeout for processing control responses
+  - `onControlRequestTimeout`: Timeout for processing control requests
+  - `onPermissionRequestTimeout`: Timeout for processing permission requests
+
+To customize timeout settings:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventConsumers;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import com.alibaba.qwen.code.cli.transport.TransportOptions;
+import com.alibaba.qwen.code.cli.utils.Timeout;
+import java.util.List;
+import java.util.concurrent.TimeUnit;
+
+public class TimeoutConfigurationExample {
+    public static void main(String[] args) {
+        // Configure transport-level timeouts
+        TransportOptions options = new TransportOptions()
+            .setTurnTimeout(new Timeout(120L, TimeUnit.SECONDS))    // Timeout for a complete turn of conversation
+            .setMessageTimeout(new Timeout(90L, TimeUnit.SECONDS));  // Timeout for individual messages within a turn
+
+        Session session = QwenCodeCli.newSession(options);
+
+        // Configure event-level timeouts using SessionEventConsumers
+        SessionEventConsumers eventConsumers = new SessionEventSimpleConsumers() {
+            @Override
+            public Timeout onSystemMessageTimeout(Session session) {
+                return new Timeout(60L, TimeUnit.SECONDS);  // Timeout for processing system messages
+            }
+
+            @Override
+            public Timeout onResultMessageTimeout(Session session) {
+                return new Timeout(60L, TimeUnit.SECONDS);  // Timeout for processing result messages
+            }
+
+            @Override
+            public Timeout onAssistantMessageTimeout(Session session) {
+                return new Timeout(90L, TimeUnit.SECONDS);  // Timeout for processing assistant messages
+            }
+
+            @Override
+            public Timeout onControlResponseTimeout(Session session) {
+                return new Timeout(45L, TimeUnit.SECONDS);  // Timeout for processing control responses
+            }
+
+            @Override
+            public Timeout onPermissionRequestTimeout(Session session) {
+                return new Timeout(30L, TimeUnit.SECONDS);  // Timeout for processing permission requests
+            }
+
+            @Override
+            public Timeout onOtherMessageTimeout(Session session) {
+                return new Timeout(35L, TimeUnit.SECONDS);  // Timeout for processing other messages
+            }
+        }.setDefaultEventTimeout(new Timeout(90L, TimeUnit.SECONDS));  // Default timeout for all events
+        session.sendPrompt("hello world", eventConsumers);
+    }
+}
+```
+
+### Thread Pool Configuration
+
+The SDK uses a thread pool for managing concurrent operations. The default thread pool configuration is defined in the `ThreadPoolConfig` class:
+
+- **Core Pool Size**: 10 threads
+- **Maximum Pool Size**: 30 threads
+- **Keep-Alive Time**: 60 seconds
+- **Queue Capacity**: 300 tasks (using LinkedBlockingQueue)
+- **Thread Naming**: "qwen_code_cli-pool-{number}"
+- **Daemon Threads**: false
+- **Rejected Execution Handler**: CallerRunsPolicy (executes the task on the calling thread when the pool is full)
+
+The thread pool can be customized in two ways:
+
+1. **Using a custom supplier**: Provide a custom `Supplier<ThreadPoolExecutor>` through the `ThreadPoolConfig.setExecutorSupplier()` method. If no custom supplier is provided, or if the supplier throws an exception, the SDK will fall back to the default thread pool configuration.
+
+2. **Modifying properties after getting the default executor**: You can retrieve the default executor using `ThreadPoolConfig.getDefaultExecutor()` and then modify its properties such as core pool size, maximum pool size, and keep-alive time.
+
+Example of custom thread pool configuration using a supplier:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.utils.ThreadPoolConfig;
+import java.util.concurrent.Executors;
+import java.util.concurrent.ThreadPoolExecutor;
+import java.util.function.Supplier;
+
+public class ThreadPoolConfigurationExample {
+    public static void main(String[] args) {
+        // Set a custom thread pool supplier
+        ThreadPoolConfig.setExecutorSupplier(new Supplier<ThreadPoolExecutor>() {
+            @Override
+            public ThreadPoolExecutor get() {
+                return (ThreadPoolExecutor) Executors.newFixedThreadPool(20);
+            }
+        });
+
+        // The SDK will now use the custom thread pool for all operations
+        Session session = QwenCodeCli.newSession();
+    }
+}
+```
+
+Example of modifying properties after getting the default executor:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.utils.ThreadPoolConfig;
+import java.util.concurrent.ThreadPoolExecutor;
+import java.util.concurrent.TimeUnit;
+
+public class ModifyThreadPoolExample {
+    public static void main(String[] args) {
+        // Get the default executor and modify its properties
+        ThreadPoolExecutor executor = ThreadPoolConfig.getDefaultExecutor();
+
+        // Modify the core pool size
+        executor.setCorePoolSize(15);
+
+        // Modify the maximum pool size
+        executor.setMaximumPoolSize(40);
+
+        // Modify the keep-alive time
+        executor.setKeepAliveTime(120, TimeUnit.SECONDS);
+
+        // The SDK will now use the modified executor for all operations
+        Session session = QwenCodeCli.newSession();
+    }
+}
+```
+
+Note that when modifying the default executor directly, you're changing the properties of the shared static instance that will affect all subsequent operations in the application. If you need different configurations for different parts of your application, using the supplier approach is recommended.
+
+### Transport Options
+
+The `TransportOptions` class allows you to configure how the SDK communicates with the Qwen Code CLI. Below are all the available options with their descriptions:
+
+- **`pathToQwenExecutable`**: Specifies the path to the Qwen Code CLI executable. By default, the SDK looks for a `qwen` command in the system PATH.
+  - Type: `String`
+  - Example: `new TransportOptions().setPathToQwenExecutable("/usr/local/bin/qwen")`
+
+- **`cwd`**: Sets the working directory for the CLI process. This affects where the CLI operates and where relative paths are resolved from.
+  - Type: `String`
+  - Example: `new TransportOptions().setCwd("/path/to/project")`
+
+- **`model`**: Specifies the AI model to use for the session (e.g., "qwen-max", "qwen-plus", "qwen3-coder-flash", etc.).
+  - Type: `String`
+  - Example: `new TransportOptions().setModel("qwen3-coder-flash")`
+
+- **`permissionMode`**: Sets the permission mode that controls tool execution. Available modes are:
+  - `PermissionMode.DEFAULT`: Write tools are denied unless approved via `canUseTool` callback or in `allowedTools`. Read-only tools execute without confirmation.
+  - `PermissionMode.PLAN`: Blocks all write tools, instructing AI to present a plan first.
+  - `PermissionMode.AUTO_EDIT`: Auto-approve edit tools (edit, write_file) while other tools require confirmation.
+  - `PermissionMode.YOLO`: All tools execute automatically without confirmation.
+  - Type: `PermissionMode`
+  - Example: `new TransportOptions().setPermissionMode(PermissionMode.YOLO)`
+
+- **`env`**: A map of environment variables to pass to the CLI process.
+  - Type: `Map<String, String>`
+  - Example: `new TransportOptions().setEnv(Map.of("ENV_VAR", "value"))`
+
+- **`maxSessionTurns`**: Limits the number of conversation turns in a session.
+  - Type: `Integer`
+  - Example: `new TransportOptions().setMaxSessionTurns(10)`
+
+- **`coreTools`**: Specifies a list of core tools that should be available to the AI.
+  - Type: `List<String>`
+  - Example: `new TransportOptions().setCoreTools(List.of("read_file", "write_file"))`
+
+- **`excludeTools`**: Specifies a list of tools to exclude from being available to the AI.
+  - Type: `List<String>`
+  - Example: `new TransportOptions().setExcludeTools(List.of("shell"))`
+
+- **`allowedTools`**: Specifies a list of tools that are pre-approved for use without additional confirmation.
+  - Type: `List<String>`
+  - Example: `new TransportOptions().setAllowedTools(List.of("read_file", "list_directory"))`
+
+- **`authType`**: Specifies the authentication type to use for the session.
+  - Type: `String`
+  - Example: `new TransportOptions().setAuthType("bearer")`
+
+- **`includePartialMessages`**: When true, enables receiving partial messages during streaming responses.
+  - Type: `Boolean`
+  - Example: `new TransportOptions().setIncludePartialMessages(true)`
+
+- **`skillsEnable`**: Enables or disables skills functionality for the session.
+  - Type: `Boolean`
+  - Example: `new TransportOptions().setSkillsEnable(true)`
+
+- **`turnTimeout`**: Sets the timeout for a complete turn of conversation (default: 60 seconds).
+  - Type: `Timeout`
+  - Example: `new TransportOptions().setTurnTimeout(new Timeout(120L, TimeUnit.SECONDS))`
+
+- **`messageTimeout`**: Sets the timeout for individual messages within a turn (default: 60 seconds).
+  - Type: `Timeout`
+  - Example: `new TransportOptions().setMessageTimeout(new Timeout(90L, TimeUnit.SECONDS))`
+
+- **`resumeSessionId`**: Specifies the ID of a previous session to resume.
+  - Type: `String`
+  - Example: `new TransportOptions().setResumeSessionId("session-12345")`
+
+- **`otherOptions`**: Allows passing additional command-line options directly to the CLI.
+  - Type: `List<String>`
+  - Example: `new TransportOptions().setOtherOptions(List.of("--verbose", "--no-cache"))`
+
+Example of using TransportOptions:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import com.alibaba.qwen.code.cli.transport.TransportOptions;
+import com.alibaba.qwen.code.cli.protocol.data.PermissionMode;
+import com.alibaba.qwen.code.cli.utils.Timeout;
+import java.util.List;
+import java.util.Map;
+import java.util.concurrent.TimeUnit;
+
+public class TransportOptionsExample {
+    public static void main(String[] args) {
+        TransportOptions options = new TransportOptions()
+            .setModel("qwen3-coder-flash")
+            .setPermissionMode(PermissionMode.AUTO_EDIT)
+            .setCwd("/path/to/working/directory")
+            .setEnv(Map.of("CUSTOM_VAR", "value"))
+            .setIncludePartialMessages(true)
+            .setTurnTimeout(new Timeout(120L, TimeUnit.SECONDS))
+            .setMessageTimeout(new Timeout(90L, TimeUnit.SECONDS))
+            .setAllowedTools(List.of("read_file", "write_file", "list_directory"));
+
+        try (Session session = QwenCodeCli.newSession(options)) {
+            // Use the session with custom options
+            List<String> result = session.sendPrompt("Analyze the current project", new SessionEventSimpleConsumers());
+            result.forEach(System.out::println);
+        }
+    }
+}
+```
+
+### Error Handling
+
+The SDK provides specific exception types for different error scenarios:
+
+- `SessionControlException`: Thrown when there's an issue with session control (creation, initialization, etc.)
+- `SessionSendPromptException`: Thrown when there's an issue sending a prompt or receiving a response
+- `SessionClosedException`: Thrown when attempting to use a closed session
+
+Example of comprehensive error handling:
+
+```java
+import com.alibaba.qwen.code.cli.QwenCodeCli;
+import com.alibaba.qwen.code.cli.session.Session;
+import com.alibaba.qwen.code.cli.session.event.SessionEventSimpleConsumers;
+import com.alibaba.qwen.code.cli.session.exception.SessionControlException;
+import com.alibaba.qwen.code.cli.session.exception.SessionSendPromptException;
+import java.util.List;
+
+public class ErrorHandlingExample {
+    public static void main(String[] args) {
+        try (Session session = QwenCodeCli.newSession()) {
+            try {
+                List<String> result = session.sendPrompt("Process this request", new SessionEventSimpleConsumers());
+                result.forEach(System.out::println);
+            } catch (SessionSendPromptException e) {
+                System.err.println("Error sending prompt: " + e.getMessage());
+                e.printStackTrace();
+            }
+        } catch (SessionControlException e) {
+            System.err.println("Error controlling session: " + e.getMessage());
+            e.printStackTrace();
+        } catch (Exception e) {
+            System.err.println("Unexpected error: " + e.getMessage());
+            e.printStackTrace();
+        }
+    }
+}
+```
+
+## FAQ / Troubleshooting
+
+### Q: Do I need to install the Qwen CLI separately?
+
+A: No, from v0.1.1, the CLI is bundled with the SDK, so no standalone CLI installation is needed.
+
+### Q: What Java versions are supported?
+
+A: The SDK requires Java 1.8 or higher.
+
+### Q: How do I handle long-running requests?
+
+A: The SDK includes timeout utilities. You can configure timeouts using the `Timeout` class in `TransportOptions`.
+
+### Q: Why are some tools not executing?
+
+A: This is likely due to permission modes. Check your permission mode settings and consider using `allowedTools` to pre-approve certain tools.
+
+### Q: How do I resume a previous session?
+
+A: Use the `setResumeSessionId()` method in `TransportOptions` to resume a previous session.
+
+### Q: Can I customize the environment for the CLI process?
+
+A: Yes, use the `setEnv()` method in `TransportOptions` to pass environment variables to the CLI process.
+
+### Q: What happens if the CLI process crashes?
+
+A: The SDK will throw appropriate exceptions. Make sure to handle `SessionControlException` and implement retry logic if needed.
