+# Qwen Code Java SDK
+
+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.
+
+## Requirements
+
+- Java >= 1.8
+- Maven >= 3.6.0 (for building from source)
+- qwen-code >= 0.5.0
+
+### 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)
+
+## Installation
+
+Add the following dependency to your Maven `pom.xml`:
+
+```xml
+<dependency>
+    <groupId>com.alibaba</groupId>
+    <artifactId>qwencode-sdk</artifactId>
+    <version>{$version}</version>
+</dependency>
+```
+
+Or if using Gradle, add to your `build.gradle`:
+
+```gradle
+implementation 'com.alibaba:qwencode-sdk:{$version}'
+```
+
+## Building and Running
+
+### Build Commands
+
+```bash
+# Compile the project
+mvn compile
+
+# Run tests
+mvn test
+
+# Package the JAR
+mvn package
+
+# Install to local repository
+mvn install
+```
+
+## Quick Start
+
+The simplest way to use the SDK is through the `QwenCodeCli.simpleQuery()` method:
+
+```java
+public static void runSimpleExample() {
+    List<String> result = QwenCodeCli.simpleQuery("hello world");
+    result.forEach(logger::info);
+}
+```
+
+For more advanced usage with custom transport options:
+
+```java
+public static void runTransportOptionsExample() {
+    TransportOptions options = new TransportOptions()
+            .setModel("qwen3-coder-flash")
+            .setPermissionMode(PermissionMode.AUTO_EDIT)
+            .setCwd("./")
+            .setEnv(new HashMap<String, String>() {{put("CUSTOM_VAR", "value");}})
+            .setIncludePartialMessages(true)
+            .setTurnTimeout(new Timeout(120L, TimeUnit.SECONDS))
+            .setMessageTimeout(new Timeout(90L, TimeUnit.SECONDS))
+            .setAllowedTools(Arrays.asList("read_file", "write_file", "list_directory"));
+
+    List<String> result = QwenCodeCli.simpleQuery("who are you, what are your capabilities?", options);
+    result.forEach(logger::info);
+}
+```
+
+For streaming content handling with custom content consumers:
+
+```java
+public static void runStreamingExample() {
+    QwenCodeCli.simpleQuery("who are you, what are your capabilities?",
+            new TransportOptions().setMessageTimeout(new Timeout(10L, TimeUnit.SECONDS)), new AssistantContentSimpleConsumers() {
+
+                @Override
+                public void onText(Session session, TextAssistantContent textAssistantContent) {
+                    logger.info("Text content received: {}", textAssistantContent.getText());
+                }
+
+                @Override
+                public void onThinking(Session session, ThingkingAssistantContent thingkingAssistantContent) {
+                    logger.info("Thinking content received: {}", thingkingAssistantContent.getThinking());
+                }
+
+                @Override
+                public void onToolUse(Session session, ToolUseAssistantContent toolUseContent) {
+                    logger.info("Tool use content received: {} with arguments: {}",
+                            toolUseContent, toolUseContent.getInput());
+                }
+
+                @Override
+                public void onToolResult(Session session, ToolResultAssistantContent toolResultContent) {
+                    logger.info("Tool result content received: {}", toolResultContent.getContent());
+                }
+
+                @Override
+                public void onOtherContent(Session session, AssistantContent<?> other) {
+                    logger.info("Other content received: {}", other);
+                }
+
+                @Override
+                public void onUsage(Session session, AssistantUsage assistantUsage) {
+                    logger.info("Usage information received: Input tokens: {}, Output tokens: {}",
+                            assistantUsage.getUsage().getInputTokens(), assistantUsage.getUsage().getOutputTokens());
+                }
+            }.setDefaultPermissionOperation(Operation.allow));
+    logger.info("Streaming example completed.");
+}
+```

+
+## Architecture
+
+The SDK follows a 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
+
+## Key Features
+
+### 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.
+
+### Session Event Consumers and Assistant Content Consumers
+
+The SDK provides two key interfaces for handling events and content from the CLI:
+
+#### SessionEventConsumers Interface
+
+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)
+
+#### AssistantContentConsumers Interface
+
+The `AssistantContentConsumers` interface handles different types of content within assistant messages:
+
+- `onText`: Handles text content (receives Session and TextAssistantContent)
+- `onThinking`: Handles thinking content (receives Session and ThingkingAssistantContent)
+- `onToolUse`: Handles tool use content (receives Session and ToolUseAssistantContent)
+- `onToolResult`: Handles tool result content (receives Session and ToolResultAssistantContent)
+- `onOtherContent`: Handles other content types (receives Session and AssistantContent)
+- `onUsage`: Handles usage information (receives Session and AssistantUsage)
+- `onPermissionRequest`: Handles permission requests (receives Session and CLIControlPermissionRequest, returns Behavior)
+- `onOtherControlRequest`: Handles other control requests (receives Session and ControlRequestPayload, returns ControlResponsePayload)
+
+#### Relationship Between the Interfaces
+
+**Important Note on Event Hierarchy:**
+
+- `SessionEventConsumers` is the **high-level** event processor that handles different message types (system, assistant, user, etc.)
+- `AssistantContentConsumers` is the **low-level** content processor that handles different types of content within assistant messages (text, tools, thinking, etc.)
+
+**Processor Relationship:**
+
+- `SessionEventConsumers` → `AssistantContentConsumers` (SessionEventConsumers uses AssistantContentConsumers to process content within assistant messages)
+
+**Event Derivation Relationships:**
+
+- `onAssistantMessage` → `onText`, `onThinking`, `onToolUse`, `onToolResult`, `onOtherContent`, `onUsage`
+- `onPartialAssistantMessage` → `onText`, `onThinking`, `onToolUse`, `onToolResult`, `onOtherContent`
+- `onControlRequest` → `onPermissionRequest`, `onOtherControlRequest`
+
+**Event Timeout Relationships:**
+
+Each event handler method has a corresponding timeout method that allows customizing the timeout behavior for that specific event:
+
+- `onSystemMessage` ↔ `onSystemMessageTimeout`
+- `onResultMessage` ↔ `onResultMessageTimeout`
+- `onAssistantMessage` ↔ `onAssistantMessageTimeout`
+- `onPartialAssistantMessage` ↔ `onPartialAssistantMessageTimeout`
+- `onUserMessage` ↔ `onUserMessageTimeout`
+- `onOtherMessage` ↔ `onOtherMessageTimeout`
+- `onControlResponse` ↔ `onControlResponseTimeout`
+- `onControlRequest` ↔ `onControlRequestTimeout`
+
+For AssistantContentConsumers timeout methods:
+
+- `onText` ↔ `onTextTimeout`
+- `onThinking` ↔ `onThinkingTimeout`
+- `onToolUse` ↔ `onToolUseTimeout`
+- `onToolResult` ↔ `onToolResultTimeout`
+- `onOtherContent` ↔ `onOtherContentTimeout`
+- `onPermissionRequest` ↔ `onPermissionRequestTimeout`
+- `onOtherControlRequest` ↔ `onOtherControlRequestTimeout`
+
+**Default Timeout Values:**
+
+- `SessionEventSimpleConsumers` default timeout: 180 seconds (Timeout.TIMEOUT_180_SECONDS)
+- `AssistantContentSimpleConsumers` default timeout: 60 seconds (Timeout.TIMEOUT_60_SECONDS)
+
+**Timeout Hierarchy Requirements:**
+
+For proper operation, the following timeout relationships should be maintained:
+
+- `onAssistantMessageTimeout` return value should be greater than `onTextTimeout`, `onThinkingTimeout`, `onToolUseTimeout`, `onToolResultTimeout`, and `onOtherContentTimeout` return values
+- `onControlRequestTimeout` return value should be greater than `onPermissionRequestTimeout` and `onOtherControlRequestTimeout` return values
+
+### Transport Options
+
+The `TransportOptions` class allows configuration of how the SDK communicates with the Qwen Code CLI:
+
+- `pathToQwenExecutable`: Path to the Qwen Code CLI executable
+- `cwd`: Working directory for the CLI process
+- `model`: AI model to use for the session
+- `permissionMode`: Permission mode that controls tool execution
+- `env`: Environment variables to pass to the CLI process
+- `maxSessionTurns`: Limits the number of conversation turns in a session
+- `coreTools`: List of core tools that should be available to the AI
+- `excludeTools`: List of tools to exclude from being available to the AI
+- `allowedTools`: List of tools that are pre-approved for use without additional confirmation
+- `authType`: Authentication type to use for the session
+- `includePartialMessages`: Enables receiving partial messages during streaming responses
+- `skillsEnable`: Enables or disables skills functionality for the session
+- `turnTimeout`: Timeout for a complete turn of conversation
+- `messageTimeout`: Timeout for individual messages within a turn
+- `resumeSessionId`: ID of a previous session to resume
+- `otherOptions`: Additional command-line options to pass to the CLI
+
+### Session Control Features
+
+- **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
+
+### Thread Pool Configuration
+
+The SDK uses a thread pool for managing concurrent operations with the following default configuration:
+
+- **Core Pool Size**: 30 threads
+- **Maximum Pool Size**: 100 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
+
+## 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
+
+## FAQ / Troubleshooting
+
+### Q: Do I need to install the Qwen CLI separately?
+
+A: yes, requires Qwen CLI 0.5.5 or higher.
+
+### 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.

+#### modelProviders
+
+Use `modelProviders` to declare curated model lists per auth type that the `/model` picker can switch between. Keys must be valid auth types (`openai`, `anthropic`, `gemini`, `vertex-ai`, etc.). Each entry requires an `id` and **must include `envKey`**, with optional `name`, `description`, `baseUrl`, and `generationConfig`. Credentials are never persisted in settings; the runtime reads them from `process.env[envKey]`. Qwen OAuth models remain hard-coded and cannot be overridden.
+
+##### Example
+
+```json
+{
+  "modelProviders": {
+    "openai": [
+      {
+        "id": "gpt-4o",

+        "envKey": "GOOGLE_API_KEY",
+        "baseUrl": "https://generativelanguage.googleapis.com"
+      }
+    ]
+  }
+}
+```
+
+> [!note]
+> Only the `/model` command exposes non-default auth types. Anthropic, Gemini, Vertex AI, etc., must be defined via `modelProviders`. The `/auth` command intentionally lists only the built-in Qwen OAuth and OpenAI flows.
+
+##### Resolution layers and atomicity
+
+The effective auth/model/credential values are chosen per field using the following precedence (first present wins). You can combine `--auth-type` with `--model` to point directly at a provider entry; these CLI flags run before other layers.
+
+| Layer (highest → lowest)   | authType                            | model                                           | apiKey                                              | baseUrl                                              | apiKeyEnvKey           | proxy                             |
+| -------------------------- | ----------------------------------- | ----------------------------------------------- | --------------------------------------------------- | ---------------------------------------------------- | ---------------------- | --------------------------------- |
+| Programmatic overrides     | `/auth `                            | `/auth` input                                   | `/auth` input                                       | `/auth` input                                        | —                      | —                                 |
+| Model provider selection   | —                                   | `modelProvider.id`                              | `env[modelProvider.envKey]`                         | `modelProvider.baseUrl`                              | `modelProvider.envKey` | —                                 |
+| CLI arguments              | `--auth-type`                       | `--model`                                       | `--openaiApiKey` (or provider-specific equivalents) | `--openaiBaseUrl` (or provider-specific equivalents) | —                      | —                                 |
+| Environment variables      | —                                   | Provider-specific mapping (e.g. `OPENAI_MODEL`) | Provider-specific mapping (e.g. `OPENAI_API_KEY`)   | Provider-specific mapping (e.g. `OPENAI_BASE_URL`)   | —                      | —                                 |
+| Settings (`settings.json`) | `security.auth.selectedType`        | `model.name`                                    | `security.auth.apiKey`                              | `security.auth.baseUrl`                              | —                      | —                                 |
+| Default / computed         | Falls back to `AuthType.QWEN_OAUTH` | Built-in default (OpenAI ⇒ `qwen3-coder-plus`)  | —                                                   | —                                                    | —                      | `Config.getProxy()` if configured |
+
+\*When present, CLI auth flags override settings. Otherwise, `security.auth.selectedType` or the implicit default determine the auth type. Qwen OAuth and OpenAI are the only auth types surfaced without extra configuration.
+
+Model-provider sourced values are applied atomically: once a provider model is active, every field it defines is protected from lower layers until you manually clear credentials via `/auth`. The final `generationConfig` is the projection across all layers—lower layers only fill gaps left by higher ones, and the provider layer remains impenetrable.
+
+The merge strategy for `modelProviders` is REPLACE: the entire `modelProviders` from project settings will override the corresponding section in user settings, rather than merging the two.
+
+##### Generation config layering
+
+Per-field precedence for `generationConfig`:
+
+1. Programmatic overrides (e.g. runtime `/model`, `/auth` changes)
+2. `modelProviders[authType][].generationConfig`
+3. `settings.model.generationConfig`
+4. Content-generator defaults (`getDefaultGenerationConfig` for OpenAI, `getParameterValue` for Gemini, etc.)
+
+`samplingParams` is treated atomically; provider values replace the entire object. Defaults from the content generator apply last so each provider retains its tuned baseline.
+
+##### Selection persistence and recommendations
+
+> [!important]
+> Define `modelProviders` in the user-scope `~/.qwen/settings.json` whenever possible and avoid persisting credential overrides in any scope. Keeping the provider catalog in user settings prevents merge/override conflicts between project and user scopes and ensures `/auth` and `/model` updates always write back to a consistent scope.
+
+- `/model` and `/auth` persist `model.name` (where applicable) and `security.auth.selectedType` to the closest writable scope that already defines `modelProviders`; otherwise they fall back to the user scope. This keeps workspace/user files in sync with the active provider catalog.
+- Without `modelProviders`, the resolver mixes CLI/env/settings layers, which is fine for single-provider setups but cumbersome when frequently switching. Define provider catalogs whenever multi-model workflows are common so that switches stay atomic, source-attributed, and debuggable.

+# Internationalization (i18n) & Language
+
+Qwen Code is built for multilingual workflows: it supports UI localization (i18n/l10n) in the CLI, lets you choose the assistant output language, and allows custom UI language packs.
+
+## Overview
+
+From a user point of view, Qwen Code’s “internationalization” spans multiple layers:
+
+| Capability / Setting     | What it controls                                                       | Where stored                 |
+| ------------------------ | ---------------------------------------------------------------------- | ---------------------------- |
+| `/language ui`           | Terminal UI text (menus, system messages, prompts)                     | `~/.qwen/settings.json`      |
+| `/language output`       | Language the AI responds in (an output preference, not UI translation) | `~/.qwen/output-language.md` |
+| Custom UI language packs | Overrides/extends built-in UI translations                             | `~/.qwen/locales/*.js`       |
+
+## UI Language
+
+This is the CLI’s UI localization layer (i18n/l10n): it controls the language of menus, prompts, and system messages.
+
+### Setting the UI Language
+
+Use the `/language ui` command:
+
+```bash
+/language ui zh-CN    # Chinese
+/language ui en-US    # English
+/language ui ru-RU    # Russian
+/language ui de-DE    # German
+```
+
+Aliases are also supported:
+
+```bash
+/language ui zh       # Chinese
+/language ui en       # English
+/language ui ru       # Russian
+/language ui de       # German
+```
+
+### Auto-detection
+
+On first startup, Qwen Code detects your system locale and sets the UI language automatically.
+
+Detection priority:
+
+1. `QWEN_CODE_LANG` environment variable
+2. `LANG` environment variable
+3. System locale via JavaScript Intl API
+4. Default: English
+
+## LLM Output Language
+
+The LLM output language controls what language the AI assistant responds in, regardless of what language you type your questions in.
+
+### How It Works
+
+The LLM output language is controlled by a rule file at `~/.qwen/output-language.md`. This file is automatically included in the LLM's context during startup, instructing it to respond in the specified language.
+
+### Auto-detection
+
+On first startup, if no `output-language.md` file exists, Qwen Code automatically creates one based on your system locale. For example:
+
+- System locale `zh` creates a rule for Chinese responses
+- System locale `en` creates a rule for English responses
+- System locale `ru` creates a rule for Russian responses
+- System locale `de` creates a rule for German responses
+
+### Manual Setting
+
+Use `/language output <language>` to change:
+
+```bash
+/language output Chinese
+/language output English
+/language output Japanese
+/language output German
+```
+
+Any language name works. The LLM will be instructed to respond in that language.
+
+> [!note]
+>
+> After changing the output language, restart Qwen Code for the change to take effect.
+
+### File Location
+
+```
+~/.qwen/output-language.md
+```
+
+## Configuration
+
+### Via Settings Dialog
+
+1. Run `/settings`
+2. Find "Language" under General
+3. Select your preferred UI language
+
+### Via Environment Variable
+
+```bash
+export QWEN_CODE_LANG=zh
+```
+
+This influences auto-detection on first startup (if you haven’t set a UI language and no `output-language.md` file exists yet).
+
+## Custom Language Packs
+
+For UI translations, you can create custom language packs in `~/.qwen/locales/`:
+
+- Example: `~/.qwen/locales/es.js` for Spanish
+- Example: `~/.qwen/locales/fr.js` for French
+
+User directory takes precedence over built-in translations.
+
+> [!tip]
+>
+> Contributions are welcome! If you’d like to improve built-in translations or add new languages.
+> For a concrete example, see [PR #1238: feat(i18n): add Russian language support](https://github.com/QwenLM/qwen-code/pull/1238).
+
+### Language Pack Format
+
+```javascript
+// ~/.qwen/locales/es.js
+export default {
+  Hello: 'Hola',
+  Settings: 'Configuracion',
+  // ... more translations
+};
+```
+
+## Related Commands

-## 🚨 MANDATORY RULE - NO EXCEPTIONS 🚨
+## Goal
+Prefer responding in **${language}** for normal assistant messages and explanations.
 
-**YOU MUST RESPOND IN ${language.toUpperCase()} FOR EVERY SINGLE OUTPUT, REGARDLESS OF THE USER'S INPUT LANGUAGE.**
+## Keep technical artifacts unchanged
+Do **not** translate or rewrite:
+- Code blocks, CLI commands, file paths, stack traces, logs, JSON keys, identifiers
+- Exact quoted text from the user (keep quotes verbatim)
 
-This is a **NON-NEGOTIABLE** requirement. Even if the user writes in English, says "hi", asks a simple question, or explicitly requests another language, **YOU MUST ALWAYS RESPOND IN ${language.toUpperCase()}.**
+## When a conflict exists
+If higher-priority instructions (system/developer) require a different behavior, follow them.
 
-## What Must Be in ${language}
-
-**EVERYTHING** you output: conversation replies, tool call descriptions, success/error messages, generated file content (comments, documentation), and all explanatory text.
-
-**Tool outputs**: All descriptive text from \`read_file\`, \`write_file\`, \`codebase_search\`, \`run_terminal_cmd\`, \`todo_write\`, \`web_search\`, etc. MUST be in ${language}.
-
-## Examples
-
-### ✅ CORRECT:
-- User says "hi" → Respond in ${language} (e.g., "Bonjour" if ${language} is French)
-- Tool result → "已成功读取文件 config.json" (if ${language} is Chinese)
-- Error → "无法找到指定的文件" (if ${language} is Chinese)
-
-### ❌ WRONG:
-- User says "hi" → "Hello" in English
-- Tool result → "Successfully read file" in English
-- Error → "File not found" in English
-
-## Notes
-
-- Code elements (variable/function names, syntax) can remain in English
-- Comments, documentation, and all other text MUST be in ${language}
-
-**THIS RULE IS ACTIVE NOW. ALL OUTPUTS MUST BE IN ${language.toUpperCase()}. NO EXCEPTIONS.**
+## Tool / system outputs
+Raw tool/system outputs may contain fixed-format English. Preserve them verbatim, and if needed, add a short **${language}** explanation below.
