+# 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?
+

+#### 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

+  "modelProviders": {
+    "openai": [

+
+> [!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                             |

+| Model provider selection   | —                                   | `modelProvider.id`                              | `env[modelProvider.envKey]`                         | `modelProvider.baseUrl`                              | `modelProvider.envKey` | —                                 |

+| 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.

+# Agent Skills (Experimental)
+
+> Create, manage, and share Skills to extend Qwen Code’s capabilities.
+
+This guide shows you how to create, use, and manage Agent Skills in **Qwen Code**. Skills are modular capabilities that extend the model’s effectiveness through organized folders containing instructions (and optionally scripts/resources).
+
+> [!note]
+>
+> Skills are currently **experimental** and must be enabled with `--experimental-skills`.
+
+## Prerequisites
+
+- Qwen Code (recent version)
+- Run with the experimental flag enabled:
+
+```bash
+qwen --experimental-skills
+```
+
+- Basic familiarity with Qwen Code ([Quickstart](../quickstart.md))
+
+## What are Agent Skills?
+
+Agent Skills package expertise into discoverable capabilities. Each Skill consists of a `SKILL.md` file with instructions that the model can load when relevant, plus optional supporting files like scripts and templates.
+
+### How Skills are invoked
+
+Skills are **model-invoked** — the model autonomously decides when to use them based on your request and the Skill’s description. This is different from slash commands, which are **user-invoked** (you explicitly type `/command`).
+
+### Benefits
+
+- Extend Qwen Code for your workflows
+- Share expertise across your team via git
+- Reduce repetitive prompting
+- Compose multiple Skills for complex tasks
+
+## Create a Skill
+
+Skills are stored as directories containing a `SKILL.md` file.
+
+### Personal Skills
+
+Personal Skills are available across all your projects. Store them in `~/.qwen/skills/`:
+
+```bash
+mkdir -p ~/.qwen/skills/my-skill-name
+```
+
+Use personal Skills for:
+
+- Your individual workflows and preferences
+- Experimental Skills you’re developing
+- Personal productivity helpers
+
+### Project Skills
+
+Project Skills are shared with your team. Store them in `.qwen/skills/` within your project:
+
+```bash
+mkdir -p .qwen/skills/my-skill-name
+```
+
+Use project Skills for:
+
+- Team workflows and conventions
+- Project-specific expertise
+- Shared utilities and scripts
+
+Project Skills can be checked into git and automatically become available to teammates.
+
+## Write `SKILL.md`
+
+Create a `SKILL.md` file with YAML frontmatter and Markdown content:
+
+```yaml
+---
+name: your-skill-name
+description: Brief description of what this Skill does and when to use it
+---
+
+# Your Skill Name
+
+## Instructions
+Provide clear, step-by-step guidance for Qwen Code.
+
+## Examples
+Show concrete examples of using this Skill.
+```
+
+### Field requirements
+
+Qwen Code currently validates that:
+
+- `name` is a non-empty string
+- `description` is a non-empty string
+
+Recommended conventions (not strictly enforced yet):
+
+- Use lowercase letters, numbers, and hyphens in `name`
+- Make `description` specific: include both **what** the Skill does and **when** to use it (key words users will naturally mention)
+
+## Add supporting files
+
+Create additional files alongside `SKILL.md`:
+
+```text
+my-skill/
+├── SKILL.md (required)
+├── reference.md (optional documentation)
+├── examples.md (optional examples)
+├── scripts/
+│   └── helper.py (optional utility)
+└── templates/
+    └── template.txt (optional template)
+```
+
+Reference these files from `SKILL.md`:
+
+````markdown
+For advanced usage, see [reference.md](reference.md).
+
+Run the helper script:
+
+```bash
+python scripts/helper.py input.txt
+```
+````
+
+## View available Skills
+
+When `--experimental-skills` is enabled, Qwen Code discovers Skills from:
+
+- Personal Skills: `~/.qwen/skills/`
+- Project Skills: `.qwen/skills/`
+
+To view available Skills, ask Qwen Code directly:
+
+```text
+What Skills are available?
+```
+
+Or inspect the filesystem:
+
+```bash
+# List personal Skills
+ls ~/.qwen/skills/
+
+# List project Skills (if in a project directory)
+ls .qwen/skills/
+
+# View a specific Skill’s content
+cat ~/.qwen/skills/my-skill/SKILL.md
+```
+
+## Test a Skill
+
+After creating a Skill, test it by asking questions that match your description.
+
+Example: if your description mentions “PDF files”:
+
+```text
+Can you help me extract text from this PDF?
+```
+
+The model autonomously decides to use your Skill if it matches the request — you don’t need to explicitly invoke it.
+
+## Debug a Skill
+
+If Qwen Code doesn’t use your Skill, check these common issues:
+
+### Make the description specific
+
+Too vague:
+
+```yaml
+description: Helps with documents
+```
+
+Specific:
+
+```yaml
+description: Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDFs, forms, or document extraction.
+```
+
+### Verify file path
+
+- Personal Skills: `~/.qwen/skills/<skill-name>/SKILL.md`
+- Project Skills: `.qwen/skills/<skill-name>/SKILL.md`
+
+```bash
+# Personal
+ls ~/.qwen/skills/my-skill/SKILL.md
+
+# Project
+ls .qwen/skills/my-skill/SKILL.md
+```
+
+### Check YAML syntax
+
+Invalid YAML prevents the Skill metadata from loading correctly.
+
+```bash
+cat SKILL.md | head -n 15
+```
+
+Ensure:
+
+- Opening `---` on line 1
+- Closing `---` before Markdown content
+- Valid YAML syntax (no tabs, correct indentation)
+
+### View errors
+
+Run Qwen Code with debug mode to see Skill loading errors:
+
+```bash
+qwen --experimental-skills --debug
+```
+
+## Share Skills with your team
+
+You can share Skills through project repositories:
+
+1. Add the Skill under `.qwen/skills/`
+2. Commit and push
+3. Teammates pull the changes and run with `--experimental-skills`
+
+```bash
+git add .qwen/skills/
+git commit -m "Add team Skill for PDF processing"
+git push
+```
+
+## Update a Skill
+
+Edit `SKILL.md` directly:
+
+```bash
+# Personal Skill
+code ~/.qwen/skills/my-skill/SKILL.md
+
+# Project Skill
+code .qwen/skills/my-skill/SKILL.md
+```
+
+Changes take effect the next time you start Qwen Code. If Qwen Code is already running, restart it to load the updates.
+
+## Remove a Skill
+
+Delete the Skill directory:
+
+```bash
+# Personal
+rm -rf ~/.qwen/skills/my-skill
+
+# Project
+rm -rf .qwen/skills/my-skill
+git commit -m "Remove unused Skill"
+```
+
+## Best practices
+
+### Keep Skills focused
+
+One Skill should address one capability:
+
+- Focused: “PDF form filling”, “Excel analysis”, “Git commit messages”
+- Too broad: “Document processing” (split into smaller Skills)
+
+### Write clear descriptions
+
+Help the model discover when to use Skills by including specific triggers:
+
+```yaml
+description: Analyze Excel spreadsheets, create pivot tables, and generate charts. Use when working with Excel files, spreadsheets, or .xlsx data.
+```
+
+### Test with your team
+
+- Does the Skill activate when expected?
+- Are the instructions clear?
+- Are there missing examples or edge cases?

 ## Authentication or login errors
 
-- **Error: `UNABLE_TO_GET_ISSUER_CERT_LOCALLY` or `unable to get local issuer certificate`**
+- **Error: `UNABLE_TO_GET_ISSUER_CERT_LOCALLY`, `UNABLE_TO_VERIFY_LEAF_SIGNATURE`, or `unable to get local issuer certificate`**
   - **Cause:** You may be on a corporate network with a firewall that intercepts and inspects SSL/TLS traffic. This often requires a custom root CA certificate to be trusted by Node.js.
   - **Solution:** Set the `NODE_EXTRA_CA_CERTS` environment variable to the absolute path of your corporate root CA certificate file.
     - Example: `export NODE_EXTRA_CA_CERTS=/path/to/your/corporate-ca.crt`
 
+- **Error: `Device authorization flow failed: fetch failed`**
+  - **Cause:** Node.js could not reach Qwen OAuth endpoints (often a proxy or SSL/TLS trust issue). When available, Qwen Code will also print the underlying error cause (for example: `UNABLE_TO_VERIFY_LEAF_SIGNATURE`).
+  - **Solution:**
+    - Confirm you can access `https://chat.qwen.ai` from the same machine/network.
+    - If you are behind a proxy, set it via `qwen --proxy <url>` (or the `proxy` setting in `settings.json`).
+    - If your network uses a corporate TLS inspection CA, set `NODE_EXTRA_CA_CERTS` as described above.
+
 - **Issue: Unable to display UI after authentication failure**
   - **Cause:** If authentication fails after selecting an authentication type, the `security.auth.selectedType` setting may be persisted in `settings.json`. On restart, the CLI may get stuck trying to authenticate with the failed auth type and fail to display the UI.
   - **Solution:** Clear the `security.auth.selectedType` configuration item in your `settings.json` file:
