### 导出副本边界与技能别名

迁移、安装、修复和经验回写只作用于当前加载的目标宿主技能副本。原 Codex 技能/MCP、下载的源码和 `original-skills` 均为来源材料，不因执行本副本而写入；只有用户另行明确要求配置 Codex 产品本身时，才按该产品流程处理指定目标。脚本需要安装目录或状态目录时，显式提供目标路径；不得从 `CODEX_HOME` 隐式推断写入位置。

跨技能名称可能沿用源库别名。先查 [技能别名表](../../skill-aliases.json)，优先选择同来源、同插件的条目，再使用其 `id` 调用或读取对应入口；不得假定旧 `$skill`、`superpowers:skill` 名称在新宿主直接注册。不能确定目标时先核对，不替换真实产品命令或 Shell 环境变量。

**调用限制：仅在用户明确调用本技能时执行，禁止模型自行选择并启动。**

## 跨宿主使用约定

本副本供支持 Agent Skills 的客户端使用。先检查当前宿主实际提供的工具、权限和已连接服务，再执行正文工作流。原文中的宿主工具标识是能力参考；只有实际发现该工具时才可调用，其他宿主应使用经核验的等价 MCP、CLI 或 API。没有等价能力的步骤必须报告不可用，不能虚构调用或完成状态。

技能资源以本技能目录为基准；输出写入当前项目中用户指定的位置。通过技能名称或自然语言触发，具体快捷命令由宿主决定。涉及真实产品、模型 API、协议字段和官方网址的名称保持原意。授权、审批、隐私和工具范围限制在迁移后仍然有效；不得为兼容而扩大权限。具体依赖与迁移说明见同目录 `PORTABILITY.md`。

## Key Differences from Windows/macOS

| Feature | Linux | Windows/Mac |
|---------|-------|-------------|
| **Canvas API** | ❌ Not available | ✅ Available |
| **Raw Data Pipe** | ✅ **ONLY option** | ✅ Available |
| **UI Integration** | Qt, GTK, SDL2, OpenGL | Win32/WinForms/WPF, Cocoa |
| **Headless Support** | ✅ Excellent (Docker) | Limited |
| **Audio** | PulseAudio required | Native |
| **Virtual Devices** | ✅ Required for headless | Optional |

## SDK Overview

The Zoom Video SDK for Linux is a C++ library optimized for:
- **Headless Bots**: Docker/WSL support, no display required
- **Raw Data Access**: Capture YUV420 video, PCM audio
- **Raw Data Injection**: Virtual camera/mic for custom media
- **Screen Sharing**: Capture or inject share data
- **Cloud Recording**: Record sessions to Zoom cloud
- **Live Streaming**: Stream to RTMP endpoints
- **Live Transcription**: Real-time speech-to-text
- **Qt/GTK Integration**: Full UI framework support

## Prerequisites

### System Requirements

- **OS**: Ubuntu 20.04+, Debian 11+, or compatible
- **Architecture**: x64 (recommended), ARM64
- **Compiler**: GCC 9+, Clang 10+
- **CMake**: 3.14 or later
- **Qt5**: Bundled with SDK (do NOT install system Qt5)

### Dependencies

```bash
sudo apt update
sudo apt install -y build-essential gcc cmake libglib2.0-dev liblzma-dev \
    libxcb-image0 libxcb-keysyms1 libxcb-xfixes0 libxcb-xkb1 libxcb-shape0 \
    libxcb-shm0 libxcb-randr0 libxcb-xtest0 libgbm1 libxtst6 libgl1 libnss3 \

# PulseAudio configuration (CRITICAL for audio)
mkdir -p ~/.config
echo "[General]" > ~/.config/zoomus.conf
echo "system.audio.type=default" >> ~/.config/zoomus.conf

# Log directory
mkdir -p ~/.zoom/logs
```

## Quick Start

```cpp
#include "zoom_video_sdk_api.h"
#include "zoom_video_sdk_interface.h"
#include "zoom_video_sdk_delegate_interface.h"

USING_ZOOM_VIDEO_SDK_NAMESPACE

// 1. Create SDK
IZoomVideoSDK* sdk = CreateZoomVideoSDKObj();

// 2. Initialize
ZoomVideoSDKInitParams init_params;
init_params.domain = "https://zoom.us";
init_params.enableLog = true;
init_params.logFilePrefix = "bot";
init_params.videoRawDataMemoryMode = ZoomVideoSDKRawDataMemoryModeHeap;
init_params.shareRawDataMemoryMode = ZoomVideoSDKRawDataMemoryModeHeap;
init_params.audioRawDataMemoryMode = ZoomVideoSDKRawDataMemoryModeHeap;

sdk->initialize(init_params);

// 3. Add delegate
sdk->addListener(myDelegate);

// 4. Join session
ZoomVideoSDKSessionContext ctx;
ctx.sessionName = "my-session";
ctx.userName = "Linux Bot";
ctx.token = "jwt-token";
ctx.audioOption.connect = true;
ctx.audioOption.mute = false;
ctx.videoOption.localVideoOn = false;

// For headless: Virtual audio speaker
ctx.virtualAudioSpeaker = new VirtualSpeaker();

IZoomVideoSDKSession* session = sdk->joinSession(ctx);
```

See **[Session Join Pattern](examples/session-join-pattern.md)** for complete code.

## Critical Gotchas

### ⚠️ CRITICAL #1: No Canvas API on Linux

**Problem**: Linux SDK does NOT have Canvas API like Windows/Mac.

**Solution**: You MUST use Raw Data Pipe and implement your own rendering.

See: **[Raw Data vs Canvas](concepts/raw-data-vs-canvas.md)**

### ⚠️ CRITICAL #2: PulseAudio Required for Audio

**Problem**: SDK requires PulseAudio for raw audio functions.

**Solution**:
```bash
sudo apt install -y pulseaudio
mkdir -p ~/.config
echo "[General]" > ~/.config/zoomus.conf
echo "system.audio.type=default" >> ~/.config/zoomus.conf
```

See: **[PulseAudio Setup](troubleshooting/pulseaudio-setup.md)**

### ⚠️ CRITICAL #3: Qt5 Dependencies

**Problem**: SDK requires Qt5 libraries (bundled, NOT system Qt5).

**Solution**:
```bash
# Copy from SDK package
cp -r samples/qt_libs/Qt/lib/* lib/zoom_video_sdk/

# Create symlinks
cd lib/zoom_video_sdk
for lib in libQt5*.so.5; do ln -sf $lib ${lib%.5}; done
```

See: **[Qt Dependencies](troubleshooting/qt-dependencies.md)**

### ⚠️ CRITICAL #4: Heap Memory Mode

Always use heap mode for raw data:

```cpp
init_params.videoRawDataMemoryMode = ZoomVideoSDKRawDataMemoryModeHeap;
init_params.shareRawDataMemoryMode = ZoomVideoSDKRawDataMemoryModeHeap;
init_params.audioRawDataMemoryMode = ZoomVideoSDKRawDataMemoryModeHeap;
```

### ⚠️ CRITICAL #5: Virtual Audio for Headless

**Problem**: Docker/headless environments have no audio devices.

**Solution**: Use virtual audio speaker and mic.

```cpp
session_context.virtualAudioSpeaker = new VirtualSpeaker();
session_context.virtualAudioMic = new VirtualMic();
```

See: **[Virtual Audio/Video](examples/virtual-audio-video.md)**

   - Once you understand this, you can implement any feature

2. **Understand Linux specifics** → [concepts/raw-data-vs-canvas.md](concepts/raw-data-vs-canvas.md)
   - **CRITICAL**: Linux has NO Canvas API - raw data ONLY

3. **Implement session join** → [examples/session-join-pattern.md](examples/session-join-pattern.md)
   - Complete working JWT + session join code

4. **Setup environment** → [troubleshooting/pulseaudio-setup.md](troubleshooting/pulseaudio-setup.md)
   - PulseAudio configuration (required for audio)
   - [troubleshooting/qt-dependencies.md](troubleshooting/qt-dependencies.md)
   - Qt5 library setup (bundled with SDK)

5. **Implement features** → Choose from examples below

## Most Critical Documents

### 1. SDK Architecture Pattern (MASTER DOCUMENT)
**[concepts/sdk-architecture-pattern.md](concepts/sdk-architecture-pattern.md)**

The universal 3-step pattern:
1. Get singleton (SDK, helpers, session, users)
2. Implement delegate (event callbacks)
3. Subscribe and use

### 2. Raw Data vs Canvas (LINUX-SPECIFIC)
**[concepts/raw-data-vs-canvas.md](concepts/raw-data-vs-canvas.md)**

**CRITICAL**: Unlike Windows/Mac, Linux SDK has NO Canvas API. You MUST use raw data pipe.

### 3. PulseAudio Setup (MOST COMMON ISSUE)
**[troubleshooting/pulseaudio-setup.md](troubleshooting/pulseaudio-setup.md)**

Audio requires PulseAudio configuration.

### 4. Qt Dependencies
**[troubleshooting/qt-dependencies.md](troubleshooting/qt-dependencies.md)**

SDK requires bundled Qt5 libraries, NOT system Qt5.

---

## Key Learnings

### Critical Discoveries:

1. **Linux has NO Canvas API**
   - Windows/Mac have Canvas API for SDK-rendered video
   - Linux MUST use Raw Data Pipe
   - See: [Raw Data vs Canvas](concepts/raw-data-vs-canvas.md)

2. **PulseAudio is MANDATORY**
   - SDK requires PulseAudio for raw audio
   - Must configure ~/.config/zoomus.conf
   - See: [PulseAudio Setup](troubleshooting/pulseaudio-setup.md)

3. **Use Bundled Qt5, NOT System Qt5**
   - SDK includes specific Qt5 versions
   - Copy from samples/qt_libs/
   - See: [Qt Dependencies](troubleshooting/qt-dependencies.md)

4. **Helpers Control YOUR Streams Only**
   - `videoHelper->startVideo()` starts YOUR camera
   - To see others, subscribe to their VideoPipe
   - See: [Singleton Hierarchy](concepts/singleton-hierarchy.md)

5. **Virtual Devices for Headless**
   - Docker/headless needs virtual audio speaker/mic
   - Set before joining session
   - See: [Session Join Pattern](examples/session-join-pattern.md)

6. **Always Use Heap Memory Mode**
   ```cpp
   init_params.videoRawDataMemoryMode = ZoomVideoSDKRawDataMemoryModeHeap;
   ```

7. **GLib Main Loop Required**
   - while/sleep loops don't dispatch SDK events
   - Must use g_main_loop_run()
   - See: [Common Issues](troubleshooting/common-issues.md)

8. **All SDK Calls Must Be on Main Thread**
   - Background thread SDK calls return error 2 (Internal_Error)
   - Use g_idle_add() to schedule on GLib main thread
   - See: [Command Channel](examples/command-channel.md)

9. **Command Channel is Session-Scoped**
   - Does NOT span across different sessions
   - Both sender and receiver must be in the same session
   - See: [Command Channel](examples/command-channel.md)
