+You are an expert in prompt engineering, specializing in optimizing AI code assistant instructions. Your task is to analyze and improve the instructions for Claude Code.
+Follow these steps carefully:
+
+1. Analysis Phase:
+Review the chat history in your context window.
+
+Then, examine the current Claude instructions, commands and config
+<claude_instructions>
+/CLAUDE.md
+/.claude/commands/*
+**/CLAUDE.md
+.claude/settings.json
+.claude/settings.local.json
+</claude_instructions>
+
+Analyze the chat history, instructions, commands and config to identify areas that could be improved. Look for:
+- Inconsistencies in Claude's responses
+- Misunderstandings of user requests
+- Areas where Claude could provide more detailed or accurate information
+- Opportunities to enhance Claude's ability to handle specific types of queries or tasks
+- New commands or improvements to a commands name, function or response
+- Permissions and MCPs we've approved locally that we should add to the config, especially if we've added new tools or require them for the command to work
+
+2. Interaction Phase:
+Present your findings and improvement ideas to the human. For each suggestion:
+a) Explain the current issue you've identified
+b) Propose a specific change or addition to the instructions
+c) Describe how this change would improve Claude's performance
+
+Wait for feedback from the human on each suggestion before proceeding. If the human approves a change, move it to the implementation phase. If not, refine your suggestion or move on to the next idea.
+
+3. Implementation Phase:
+For each approved change:
+a) Clearly state the section of the instructions you're modifying
+b) Present the new or modified text for that section
+c) Explain how this change addresses the issue identified in the analysis phase
+
+4. Output Format:
+Present your final output in the following structure:
+
+<analysis>
+[List the issues identified and potential improvements]
+</analysis>
+
+<improvements>
+[For each approved improvement:
+1. Section being modified
+2. New or modified instruction text
+3. Explanation of how this addresses the identified issue]
+</improvements>
+
+<final_instructions>
+[Present the complete, updated set of instructions for Claude, incorporating all approved changes]
+</final_instructions>
+
+Remember, your goal is to enhance Claude's performance and consistency while maintaining the core functionality and purpose of the AI assistant. Be thorough in your analysis, clear in your explanations, and precise in your implementations.

+  - `src/server/` - Audio/clipboard/input/video services and network connections
+  - `src/client.rs` - Peer connection handling
+  - `src/platform/` - Platform-specific code
+- **`flutter/`** - Flutter UI code for desktop and mobile
+- **`libs/`** - Core libraries
+  - `libs/hbb_common/` - Video codec, config, network wrapper, protobuf, file transfer utilities
+  - `libs/scrap/` - Screen capture functionality
+  - `libs/enigo/` - Platform-specific keyboard/mouse control
+  - `libs/clipboard/` - Cross-platform clipboard implementation
+
+### Key Components
+- **Remote Desktop Protocol**: Custom protocol implemented in `src/rendezvous_mediator.rs` for communicating with rustdesk-server
+- **Screen Capture**: Platform-specific screen capture in `libs/scrap/`
+- **Input Handling**: Cross-platform input simulation in `libs/enigo/`
+- **Audio/Video Services**: Real-time audio/video streaming in `src/server/`
+- **File Transfer**: Secure file transfer implementation in `libs/hbb_common/`
+
+### UI Architecture
+- **Legacy UI**: Sciter-based (deprecated) - files in `src/ui/`
+- **Modern UI**: Flutter-based - files in `flutter/`
+  - Desktop: `flutter/lib/desktop/`
+  - Mobile: `flutter/lib/mobile/`
+  - Shared: `flutter/lib/common/` and `flutter/lib/models/`
+
+## Important Build Notes
+
+### Dependencies
+- Requires vcpkg for C++ dependencies: `libvpx`, `libyuv`, `opus`, `aom`
+- Set `VCPKG_ROOT` environment variable
+- Download appropriate Sciter library for legacy UI support
+
+### Ignore Patterns
+When working with files, ignore these directories:
+- `target/` - Rust build artifacts
+- `flutter/build/` - Flutter build output
+- `flutter/.dart_tool/` - Flutter tooling files
+
+### Cross-Platform Considerations
+- Windows builds require additional DLLs and virtual display drivers
+- macOS builds need proper signing and notarization for distribution
+- Linux builds support multiple package formats (deb, rpm, AppImage)
+- Mobile builds require platform-specific toolchains (Android SDK, Xcode)
+
+### Feature Flags
+- `hwcodec` - Hardware video encoding/decoding
+- `vram` - VRAM optimization (Windows only)
+- `flutter` - Enable Flutter UI
+- `unix-file-copy-paste` - Unix file clipboard support
+- `screencapturekit` - macOS ScreenCaptureKit (macOS only)
+
+### Config
+All configurations or options are under `libs/hbb_common/src/config.rs` file, 4 types:
+- Settings
+- Local
+- Display
+- Built-in

+# RustDesk에 기여하기
+
+RustDesk는 모든 분들의 기여를 환영합니다. RustDesk에 기여하고 싶으시다면 아래 가이드를 참고해 주세요:
+
+## 기여 방법
+
+RustDesk 프로젝트 또는 관련 라이브러리에 대한 기여는 GitHub 풀 리퀘스트(Pull Request) 형태로 이루어져야 합니다.
+각 풀 리퀘스트는 핵심 기여자(패치 적용 권한이 있는 사람)가 검토하며,
+메인 브랜치에 통합되거나 필요한 변경 사항에 대한 피드백을 받게 됩니다.
+핵심 기여자를 포함한 모든 기여자는 이 형식을 따라야 합니다.
+
+특정 이슈에 대해 작업하고 싶다면, 먼저 해당 GitHub 이슈에 댓글을 달아 작업 의사를 알려주세요.
+이는 여러 기여자가 동일한 이슈에 대해 중복으로 작업하는 것을 방지하기 위함입니다.
+
+## 풀 리퀘스트 체크리스트
+
+- master 브랜치에서 새 브랜치를 만들고, 필요한 경우 Pull Request를 제출하기 전에 현재 master
+  브랜치로 리베이스하세요. master 브랜치와 깔끔하게 병합(merge)되지 않으면 변경 사항을
+  리베이스하도록 요청받을 수 있습니다.
+
+- 커밋(commit)은 가능한 한 작게 유지하고, 각 커밋이 독립적으로 올바른지 (즉, 각 커밋이 컴파일되고 테스트를 통과하는지) 확인해야 합니다.
+
+- 커밋에는 개발자 원본 증명서(DCO, Developer Certificate of Origin - http://developercertificate.org) 서명이 포함되어야 합니다. 이는 기여자(해당하는 경우
+  기여자의 고용주 포함)가 [프로젝트 라이선스](../LICENCE) 조건에 동의함을 의미합니다.
+  Git에서는 `git commit` 명령어에 `-s` 옵션을 사용합니다.
+
+- 패치가 검토되지 않거나 특정 리뷰어의 검토가 필요하다면, 풀 리퀘스트나 댓글에서
+  @멘션으로 리뷰어에게 알리거나 [이메일](mailto:info@rustdesk.com)로 검토를 요청할 수 있습니다.
+
+- 수정한 버그나 추가한 기능과 관련된 테스트 코드를 포함해 주세요.
+
+Git 사용에 대한 자세한 내용은 [GitHub workflow 101](https://github.com/servo/servo/wiki/GitHub-workflow) 문서를 참고하세요.

+## 의존성
+
+데스크톱 버전은 GUI에 Flutter 또는 Sciter (지원 중단됨)를 사용합니다. 이 튜토리얼은 Sciter 전용이며, 시작하기 더 쉽고 친숙하기 때문입니다. Flutter 버전 빌드는 [CI](https://github.com/rustdesk/rustdesk/blob/master/.github/workflows/flutter-build.yml)를 확인하세요.

-## Docker에 빌드하는 방법
+## Docker로 빌드하는 방법
 
-리포지토리를 클론하고, Docker 컨테이너 구성하는 것으로 시작합니다.
+먼저 리포지토리를 복제하고 Docker 컨테이너를 빌드합니다:
 
 ```sh
 git clone https://github.com/rustdesk/rustdesk
 cd rustdesk
+git submodule update --init --recursive
 docker build -t "rustdesk-builder" .
 ```
 
-이후, 애플리케이션을 빌드할 필요가 있을 때마다, 아래의의 명령을 실행합니다.
+그 다음, 애플리케이션을 빌드하려면 다음 명령을 실행하세요:
 
 ```sh
 docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder
 ```
 
-첫 빌드에서는 의존관계가 캐시될 때까지 시간이 걸릴 수 있습니다만, 이후의 빌드때는 빨라집니다. 더불어 빌드 명령에 다른 인수를 지정할 필요가 있다면, 명령 끝에 있는 `<OPTIONAL-ARGS>` 에 지정할 수 있습니다. 예를 들어 최적화된 출시 버전을 빌드하고 싶다면 이렇게 상기한 명령 뒤에 `--release` 를 붙여 실행합니다. 성공했다면 실행파일은 시스템 타겟 폴더에 담겨지고, 다음 명령으로 실행할 수 있습니다.
+첫 빌드 시에는 의존성이 캐시되느라 시간이 더 걸릴 수 있지만, 그 이후 빌드부터는 더 빨라집니다. 빌드 명령에 다른 인수를 추가하고 싶다면, 명령 끝의 `<OPTIONAL-ARGS>` 부분에 지정하세요. 예를 들어, 최적화된 릴리즈 버전을 빌드하고 싶다면 위 명령 뒤에 `--release`를 붙여 실행합니다. 결과 실행 파일은 시스템의 target 폴더에 생성되며, 다음 명령으로 실행할 수 있습니다:
 
 ```sh
 target/debug/rustdesk
 ```
 
-혹은 출시용 실행 파일을 실행할 수도 있습니다.
+또는, 릴리즈 실행 파일을 실행하는 경우:
 
 ```sh
 target/release/rustdesk
 ```
 
-명령을 RustDesk 리포지토리 루트에서 실행한다는 것을 확인해주세요. 그렇게 하지 않으면 애플리케이션이 필요한 리소스를 발견하지 못 할 가능성이 있습니다. 또한 `install`, `run` 같은 cargo 하위 명령은 호스트가 아니라 컨테이너 프로그램을 설치, 실행을 위함이므로 현재 이 방법은 지원하지 않다는 점을 유념해주시길 바랍니다.
+이 명령들은 RustDesk 리포지토리의 루트 디렉토리에서 실행해야 합니다. 그렇지 않으면 애플리케이션이 필요한 리소스를 찾지 못할 수 있습니다. 또한, `install` 또는 `run`과 같은 cargo 하위 명령은 호스트가 아닌 컨테이너 내부에 프로그램을 설치하거나 실행하므로 현재 이 방식은 지원되지 않습니다. 이 점에 유의해 주세요.

+# iOS Audio Capture Implementation
+
+## Overview
+
+RustDesk iOS audio capture is implemented following the existing audio service pattern, capturing app audio by default and sending it to peers using the Opus codec.
+
+## Architecture
+
+### Components
+
+1. **Native Layer** (`libs/scrap/src/ios/native/ScreenCapture.m`)
+   - Captures audio using ReplayKit's audio sample buffers
+   - Supports both app audio and microphone audio
+   - Converts audio format information for Rust processing
+
+2. **FFI Layer** (`libs/scrap/src/ios/ffi.rs`)
+   - Provides safe Rust bindings for audio control
+   - `enable_audio(mic: bool, app_audio: bool)` - Enable/disable audio sources
+   - `set_audio_callback()` - Register callback for audio data
+
+3. **Audio Service** (`src/server/audio_service.rs::ios_impl`)
+   - Follows the same pattern as other platforms
+   - Uses Opus encoder with 48kHz stereo configuration
+   - Processes audio in 10ms chunks (480 samples)
+   - Sends encoded audio as `AudioFrame` messages
+
+## Audio Flow
+
+1. **Capture**: ReplayKit provides audio as Linear PCM in CMSampleBuffer format
+2. **Callback**: Native code passes raw PCM data to Rust via FFI callback
+3. **Conversion**: Rust converts audio data from i16 to f32 normalized [-1.0, 1.0]
+4. **Encoding**: Opus encoder compresses audio for network transmission
+5. **Transmission**: Encoded audio sent to peers as protobuf messages
+
+## Configuration
+
+- **Sample Rate**: 48,000 Hz (standard for all platforms)
+- **Channels**: 2 (Stereo)
+- **Format**: Linear PCM, typically 16-bit
+- **Encoder**: Opus with LowDelay application mode
+- **Frame Size**: 480 samples (10ms at 48kHz)
+
+## Usage
+
+By default, app audio is captured automatically when screen recording starts:
+
+```rust
+// In audio_service.rs
+enable_audio(false, true); // mic=false, app_audio=true
+```
+
+To enable microphone:
+```rust
+enable_audio(true, true); // mic=true, app_audio=true
+```
+
+## Permissions
+
+- **App Audio**: No additional permission required (part of screen recording)
+- **Microphone**: Requires `NSMicrophoneUsageDescription` in Info.plist
+
+## Implementation Details
+
+### Audio Format Handling
+
+The native layer logs audio format on first capture:
+```
+Audio format - Sample rate: 48000, Channels: 2, Bits per channel: 16, Format: 1819304813
+```
+
+### Zero Detection
+
+Like other platforms, implements audio zero gate to avoid sending silent frames:
+- Tracks consecutive zero frames
+- Stops sending after 800 frames of silence
+- Resumes immediately when audio detected
+
+### Thread Safety
+
+- Audio callback runs on ReplayKit's audio queue
+- Uses Rust channels for thread-safe communication
+- Non-blocking receive in service loop
+
+## Limitations
+
+- Audio only available during active screen capture
+- System audio requires Broadcast Upload Extension
+- Audio/video synchronization handled separately

+
+## Implementation Components
+
+### 1. Native Layer (Objective-C)
+
+#### ScreenCapture.h - C Interface
+```objective-c
+// Video capture
+void ios_capture_init(void);
+bool ios_capture_start(void);
+void ios_capture_stop(void);
+uint32_t ios_capture_get_frame(uint8_t* buffer, uint32_t buffer_size, 
+                               uint32_t* out_width, uint32_t* out_height);
+
+// Audio capture
+void ios_capture_set_audio_enabled(bool enable_mic, bool enable_app_audio);
+typedef void (*audio_callback_t)(const uint8_t* data, uint32_t size, bool is_mic);
+void ios_capture_set_audio_callback(audio_callback_t callback);
+
+// System-wide capture
+void ios_capture_show_broadcast_picker(void);
+bool ios_capture_is_broadcasting(void);
+```
+
+#### ScreenCapture.m - Implementation Details
+- Uses `RPScreenRecorder` for in-app capture
+- Handles both video and audio sample buffers
+- Converts BGRA to RGBA pixel format
+- Thread-safe frame buffer management
+- CFMessagePort for IPC with broadcast extension
+
+### 2. FFI Layer (Rust)
+
+#### ffi.rs - Safe Rust Bindings
+```rust
+pub fn init() 
+pub fn start_capture() -> bool
+pub fn stop_capture()
+pub fn get_frame() -> Option<(Vec<u8>, u32, u32)>
+pub fn enable_audio(mic: bool, app_audio: bool)
+pub fn set_audio_callback(callback: Option<extern "C" fn(*const u8, u32, bool)>)
+pub fn show_broadcast_picker()
+```
+
+Key features:
+- Lazy static buffers to reduce allocations
+- Callback mechanism for asynchronous frame updates
+- Thread-safe frame buffer access
+
+### 3. Rust Capture Implementation
+
+#### mod.rs - Capturer Implementation
+```rust
+pub struct Capturer {
+    width: usize,
+    height: usize,
+    display: Display,
+    frame_data: Vec<u8>,
+    last_frame: Vec<u8>,
+}
+
+impl TraitCapturer for Capturer {
+    fn frame<'a>(&'a mut self, timeout: Duration) -> io::Result<crate::Frame<'a>>
+}
+```
+
+Features:
+- Implements RustDesk's `TraitCapturer` interface
+- Frame deduplication using `would_block_if_equal`
+- Automatic cleanup on drop
+- Compatible with existing video pipeline
+
+### 4. Audio Service Integration
+
+#### audio_service.rs - iOS Audio Module
+```rust
+#[cfg(target_os = "ios")]
+mod ios_impl {
+    const SAMPLE_RATE: u32 = 48000;
+    const CHANNELS: u16 = 2;
+    const FRAMES_PER_BUFFER: usize = 480; // 10ms
+    
+    pub struct State {
+        encoder: Option<Encoder>,
+        receiver: Option<Receiver<Vec<f32>>>,
+        // ...
+    }
+}
+```
+
+Features:
+- Opus encoder with 48kHz stereo
+- PCM i16 to f32 conversion
+- Zero detection for silence gating
+- Non-blocking audio processing
+
+### 5. Broadcast Upload Extension
+
+For system-wide capture (captures other apps):
+
+#### SampleHandler.m
+- Runs in separate process
+- Captures entire screen
+- Sends frames via CFMessagePort to main app
+- Memory-efficient frame transfer
+
+## Capture Modes
+
+### 1. In-App Capture (Default)
+```rust
+// Captures only RustDesk app
+let display = Display::primary()?;
+let mut capturer = Capturer::new(display)?;
+```
+
+### 2. System-Wide Capture
+```rust
+// Shows iOS broadcast picker
+ffi::show_broadcast_picker();
+// User must manually start from Control Center
+```
+
+## Build Configuration
+
+### Cargo.toml
+```toml
+[build-dependencies]
+cc = "1.0"  # For compiling Objective-C
+```
+
+### build.rs
+```rust
+if target_os == "ios" {
+    cc::Build::new()
+        .file("src/ios/native/ScreenCapture.m")
+        .flag("-fobjc-arc")
+        .flag("-fmodules")
+        .compile("ScreenCapture");
+}
+```
+
+### Info.plist Permissions
+```xml
+<key>NSMicrophoneUsageDescription</key>
+<string>This app needs microphone access for screen recording with audio</string>
+```
+
+## Data Flow
+
+### Video Capture Flow
+1. ReplayKit captures screen → CMSampleBuffer
+2. Native code converts BGRA → RGBA
+3. Frame callback or polling from Rust
+4. Rust checks for duplicate frames
+5. Creates `Frame::PixelBuffer` for video pipeline
+6. Existing video encoder/transmission
+
+### Audio Capture Flow
+1. ReplayKit captures app audio → CMSampleBuffer
+2. Native extracts Linear PCM data
+3. FFI callback to Rust audio service
+4. Convert i16 PCM → f32 normalized
+5. Opus encoding at 48kHz
+6. Send as `AudioFrame` protobuf
+
+## Memory Management
+
+### Optimizations
+- Reuse static buffers for frame data (33MB max)
+- Lazy allocation based on actual frame size
+- Frame deduplication to avoid redundant processing
+- Proper synchronization with `@synchronized` blocks
+- Weak references in completion handlers
+
+### Cleanup
+- `dealloc` method for CFMessagePort cleanup
+- Drop implementation stops capture
+- Automatic buffer cleanup
+
+## Performance Considerations
+
+### Frame Rate
+- 30-60 FPS depending on device
+- Frame skipping in broadcast extension (every 2nd frame)
+- Non-blocking frame retrieval
+
+### Latency
+- In-app: ~2-5ms capture latency
+- System-wide: ~10-20ms (IPC overhead)
+- Audio: ~10ms chunks for low latency
+
+### CPU Usage
+- Hardware-accelerated capture
+- Efficient pixel format conversion
+- Minimal memory copies
+
+## Security & Privacy
+
+### Permissions Required
+- Screen Recording (always required)
+- Microphone (optional, for mic audio)
+
+### User Control
+- Recording indicator shown by iOS
+- User must grant permission
+- Can stop anytime from Control Center
+
+### App Groups (for Broadcast Extension)
+```
+group.com.carriez.rustdesk.screenshare
+```
+
+## Integration with RustDesk
+
+### Video Service
+- Works with existing `scrap` infrastructure
+- Compatible with all video encoders (VP8/9, H264/5)
+- Standard frame processing pipeline
+
+### Audio Service
+- Integrated as platform-specific implementation
+- Same Opus encoding as other platforms
+- Compatible with existing audio routing
+
+## Limitations
+
+1. **No cursor capture** - iOS doesn't expose cursor
+2. **Permission required** - User must explicitly allow
+3. **Broadcast extension memory** - Limited to ~50MB
+4. **Background execution** - Limited by iOS policies
+
+## Testing
+
+### Build for iOS
+```bash
+cd flutter
+flutter build ios
+```
+
+### Required Setup in Xcode
+1. Add Broadcast Upload Extension target
+2. Configure app groups
+3. Set up code signing
+4. Link ReplayKit framework
+
+### Test Scenarios
+1. In-app screen capture
+2. System-wide broadcast
+3. Audio capture (app/mic)
+4. Permission handling
+5. Background/foreground transitions
+
+## Troubleshooting
+
+### Common Issues
+
+1. **No frames received**
+   - Check screen recording permission
+   - Verify capture is started
+   - Check frame timeout settings
+
+2. **Audio not working**
+   - Verify microphone permission
+   - Check audio callback registration
+   - Confirm audio format compatibility
+
+3. **Broadcast extension not appearing**
+   - Verify bundle identifiers
+   - Check code signing
+   - Ensure extension is included in build
+
+4. **Memory warnings**
+   - Reduce frame rate in broadcast extension
+   - Check buffer allocations
+   - Monitor memory usage
+
+## Future Improvements
+
+1. **Hardware encoding** - Use VideoToolbox for H.264
+2. **Adaptive quality** - Adjust based on network/CPU
+3. **Picture-in-Picture** - Support PiP mode
+4. **Screen orientation** - Better rotation handling
+5. **Audio enhancements** - Noise suppression, echo cancellation
+
+## Conclusion
+
+This implementation provides full screen and audio capture capabilities for iOS while maintaining compatibility with RustDesk's cross-platform architecture. The use of FFI minimizes overhead while allowing native iOS features to be accessed from Rust code.
