+
+   This creates a symbolic link from `../docs` to `content` in the docs-site project, allowing the documentation content to be served by the Next.js site.
+
+4. Start the development server:
+
+   ```bash
+   npm run dev

 ## 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
-   ```

+## Authentication
 
-**Option 1: Alibaba Cloud ModelStudio** ([Apply for API Key](https://modelstudio.console.alibabacloud.com/))
+Qwen Code supports two authentication methods:
+
+- **Qwen OAuth (recommended & free)**: sign in with your `qwen.ai` account in a browser.
+- **OpenAI-compatible API**: use `OPENAI_API_KEY` (and optionally a custom base URL / model).
+
+#### Qwen OAuth (recommended)
+
+Start `qwen`, then run:
 
 ```bash
-export OPENAI_API_KEY="your_api_key_here"
-export OPENAI_BASE_URL="https://dashscope-intl.aliyuncs.com/compatible-mode/v1"
-export OPENAI_MODEL="qwen3-coder-plus"
+/auth
 ```
 
-**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

+# 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?

   - `port` (number, required): The port of the MCP server.
   - `workspacePath` (string, required): A list of all open workspace root paths, delimited by the OS-specific path separator (`:` for Linux/macOS, `;` for Windows). The CLI uses this path to ensure it's running in the same project folder that's open in the IDE. If the CLI's current working directory is not a sub-directory of `workspacePath`, the connection will be rejected. Your plugin **MUST** provide the correct, absolute path(s) to the root of the open workspace(s).
   - `authToken` (string, required): A secret token for securing the connection. The CLI will include this token in an `Authorization: Bearer <token>` header on all requests.
-  - `ideInfo` (object, required): Information about the IDE.
-    - `name` (string, required): A short, lowercase identifier for the IDE (e.g., `vscode`, `jetbrains`).

The CLI will then include this token in the `Authorization` header for all requests to the MCP server (e.g., `Authorization: Bearer a-very-secret-token`). Your server **MUST** validate this token on every request and reject any that are unauthorized.
-- **Tie-Breaking with Environment Variables (Recommended):** For the most reliable experience, your plugin **SHOULD** both create the discovery file and set the `QWEN_CODE_IDE_SERVER_PORT` environment variable in the integrated terminal. The file serves as the primary discovery mechanism, but the environment variable is crucial for tie-breaking. If a user has multiple IDE windows open for the same workspace, the CLI uses the `QWEN_CODE_IDE_SERVER_PORT` variable to identify and connect to the correct window's server.
+- **Environment Variables (Required):** Your plugin **MUST** set `QWEN_CODE_IDE_SERVER_PORT` in the integrated terminal so the CLI can locate the correct `<PORT>.lock` file.
+
+**Legacy note:** For extensions older than v0.5.1, Qwen Code may fall back to reading JSON files in the system temp directory named `qwen-code-ide-server-<PID>.json` or `qwen-code-ide-server-<PORT>.json`. New integrations should not rely on these legacy files.

   - A: Cached token information is only displayed when cached tokens are being used. This feature is available for API key users (Qwen API key or Google Cloud Vertex AI) but not for OAuth users (such as Google Personal/Enterprise accounts like Google Gmail or Google Workspace, respectively). This is because the Qwen Code Assist API does not support cached content creation. You can still view your total token usage using the `/stats` command.
