+# MosisService Agent Guidelines
+
+## Build, Lint, and Test Commands
+
+### Build Commands
+- `./gradlew build` - Build the entire project
+- `./gradlew assembleDebug` - Build debug version
+- `./gradlew assembleRelease` - Build release version
+- `./gradlew clean` - Clean build outputs
+- `./gradlew :app:build` - Build specific module (if needed)
+
+### Lint Commands
+- `./gradlew lint` - Run lint checks
+- `./gradlew lintDebug` - Run lint for debug build
+- `./gradlew lintRelease` - Run lint for release build
+
+### Test Commands
+- `./gradlew test` - Run unit tests
+- `./gradlew connectedAndroidTest` - Run connected device tests
+- `./gradlew testDebugUnitTest` - Run debug unit tests
+- `./gradlew testReleaseUnitTest` - Run release unit tests
+- `./gradlew :app:test` - Run tests for specific module
+- `./gradlew :app:testDebugUnitTest` - Test specific module debug unit tests
+
+**Important Note:** The project contains C++ native code that uses CMake with both `mosis-service` and `mosis-test` libraries defined in `CMakeLists.txt`. Tests are built as shared libraries with the suffix `.so`.
+
+## Code Style Guidelines
+
+### Naming Conventions
+- `PascalCase` for class and function names (e.g., `MosisService`, `RenderTexture`)
+- `camelCase` for variables and parameters (e.g., `renderTarget`, `inputData`)
+- `UPPER_CASE` for constants (e.g., `MAX_BUFFER_SIZE`, `DEFAULT_TIMEOUT`)
+- Class names should be descriptive and follow Android naming conventions (e.g., `MosisService`)
+- Files should use meaningful names that match their content
+
+### Imports & Formatting
+- Import statements are grouped logically: Android imports, third-party imports, first-party imports
+- Imports are sorted alphabetically within each group
+- Use of fully qualified names is allowed for clarity when needed
+
+### Types & Variables
+- Use primitive types when possible
+- Use `final` keyword for constants
+- Prefer `val` over `var` in Kotlin
+- Use `final` for native C++ variables that don't change
+- Use appropriate data types (int, long, float, double) based on precision requirements
+
+### Error Handling
+- C++ code uses standard C++ exception handling
+- Android code leverages standard Android error handling patterns
+- Use try-catch blocks appropriately in Kotlin code
+- Log errors via Android's logging framework in Kotlin
+- C++ logging via `logger.cpp` component
+
+### Coding Standards
+- Follow Android development best practices
+- C++ code should follow modern C++23 conventions (including use of std::span, std::format, etc.)
+- Use RAII (Resource Acquisition Is Initialization) principles in C++
+- Ensure memory management is handled properly in native code
+- Avoid magic numbers in C++ code - use constants instead
+- Use smart pointers like `std::unique_ptr` and `std::shared_ptr` where appropriate
+- Proper resource cleanup in destructors
+- Avoid memory leaks in C++ components
+
+### Structure
+- Kotlin code following Android project structures
+- C++ code organized in separate files within `src/main/cpp/`
+- Clear separation between platform-specific code and shared logic
+- Use Android build system capabilities for multi-architecture support
+- Follow Gradle conventions for dependency management

+# MosisService Architecture
+
+## Overview
+MosisService is an Android application that combines Kotlin UI components with native C++ libraries for UI rendering and system interaction. The architecture is built around a service-oriented design using Android's Binder system and integrates with RmlUi for rich UI rendering.
+
+## Core Components
+
+### 1. Service Layer (mosis-service)
+- **Purpose**: Main Android Binder service implementation
+- **Interface**: Implements `IMosisService.aidl` 
+- **Functionality**:
+  - Touch event processing (onTouchDown, onTouchMove, onTouchUp)
+  - Service initialization and listener management
+  - Integration with kernel-based rendering system
+  - Asset loading through Android AssetManager
+
+### 2. Rendering Layer (mosis-test)
+- **Purpose**: UI rendering and testing infrastructure
+- **Interface**: Implements `IMosisListener.aidl`
+- **Functionality**:
+  - OpenGL ES 2.0 rendering pipeline using GLAD
+  - Multi-threaded rendering with EGL context management
+  - Surface and buffer handling for Android native windows
+  - Task queue management for asynchronous rendering operations
+  - Hardware buffer management and processing
+
+### 3. Core Engine (Kernel)
+- **Purpose**: Central rendering and event processing engine
+- **Components**:
+  - RmlUi-based UI rendering engine
+  - EGL context creation and management
+  - Render target handling
+  - Touch event processing and UI updates
+  - Multi-threaded execution using std::thread
+
+### 4. Supporting Libraries
+- **AssetsManager**: Asset loading from Android AssetManager
+- **Logger**: Cross-platform logging system
+- **EGL Context**: OpenGL ES context management
+- **Render Target**: Framebuffer and buffer management
+- **Shader**: OpenGL shader program handling
+- **External Texture**: Hardware buffer texture creation
+
+## System Architecture
+
+### Android Binder Integration
+- Uses AIDL (Android Interface Definition Language) for cross-process communication
+- Service exposes `IMosisService` interface for touch events and initialization
+- Listener pattern with `IMosisListener` for rendering callbacks
+- Binds to Java/Kotlin components through JNI
+
+### Multi-threading Model
+- Service layer runs in main thread for event handling
+- Rendering loop runs in dedicated thread managed by Kernel
+- Async task processing for UI updates
+- Thread-safe communication between components
+
+### Rendering Pipeline
+1. **Initialization**: Service connects to test layer, creates EGL context
+2. **Buffer Management**: Hardware buffers allocated and shared between layers
+3. **Event Processing**: Touch events processed and forwarded to Kernel
+4. **Rendering Loop**: Continuous rendering with frame synchronization
+5. **UI Updates**: RmlUi engine updates UI based on events and data
+
+### Data Flow
+```
+User Touch Events → IMosisService.onTouch* → Kernel.process → RmlUi UI Updates
+Service Initialized → IMosisListener.onServiceInitialized → Rendering Setup
+Buffer Available → IMosisListener.onBufferAvailable → Texture Creation
+Frame Available → IMosisListener.onFrameAvailable → Frame Rendering
+```
+
+## Key Technologies
+- **Android NDK**: Native development with C++23
+- **CMake**: Build system for native libraries
+- **RmlUi**: UI rendering engine with HTML/CSS-like markup
+- **OpenGL ES 2.0**: Graphics rendering
+- **GLAD**: OpenGL loader library
+- **AIDL**: Inter-process communication
+- **Binder**: Android's IPC mechanism
+
+## File Structure
+- `mosis-service.cpp`: Main service implementation
+- `mosis-test.cpp`: Test/rendering implementation  
+- `kernel.cpp`: Core rendering engine and event processing
+- `assets_manager.cpp`: Asset loading utilities
+- `egl_context.cpp`: EGL context management
+- `render_target.cpp`: Framebuffer handling
+- `logger.cpp`: Cross-platform logging
+
+## Code Standards
+- Modern C++23 with smart pointers and RAII
+- Thread-safe operations using std::mutex
+- Resource management with proper cleanup
+- Use of std::span, std::format for modern features
+- Cross-platform compatibility through Android NDK

+## Architecture Overview
+
+MosisService is an Android application combining Kotlin UI with native C++ libraries for UI rendering via Android's Binder IPC system.
+
+### Two Native Libraries
+
+**mosis-service** (`libmosis-service.so`):
+- Main Android Binder service implementation
+- Implements `IMosisService.aidl` interface for touch events and initialization
+- Contains the Kernel rendering engine with RmlUi integration
+- Links against RmlUi for HTML/CSS-like UI rendering
+
+**mosis-test** (`libmosis-test.so`):
+- Test/rendering client implementation
+- Implements `IMosisListener.aidl` for receiving callbacks
+- OpenGL ES 2.0 rendering pipeline using GLAD
+
+### IPC Flow
+
+```
+Kotlin NativeService → JNI → mosis-service (IMosisService)
+                              ↓
+                         IMosisListener callbacks
+                              ↓
+                         mosis-test (rendering client)
+```
+
+### Key Interfaces (AIDL)
+
+`IMosisService`: `initOS()`, `onTouchDown()`, `onTouchMove()`, `onTouchUp()`
+
+`IMosisListener` (oneway/async): `onServiceInitialized()`, `onBufferAvailable()`, `onFrameAvailable()`
+
+### Native Code Structure (src/main/cpp/)
+
+- `kernel.cpp` - Core rendering engine, RmlUi integration, event processing
+- `mosis-service.cpp` - Binder service implementation, JNI entry points
+- `mosis-test.cpp` - Test client implementation
+- `egl_context.cpp` - OpenGL ES context management
+- `render_target.cpp` - Framebuffer and buffer management
+- `RmlUi_Renderer_GL3.cpp` - RmlUi OpenGL renderer backend
+- `assets_manager.cpp` - Android AssetManager integration
+
+## Code Style
+
+- C++23 standard with modern features (std::span, std::format)
+- PascalCase for classes/functions, camelCase for variables
+- RAII principles with smart pointers
+- Kotlin code follows Android conventions
+
+## Dependencies
+
+- vcpkg manages native dependencies (RmlUi)
+- CMake build system with vcpkg toolchain integration
+- Target architecture: arm64-v8a only

+# MosisService Implementation Plan
+
+## Overview
+This document outlines the implementation plan for adding Lua scripting support to the MosisService project, enabling interactive UI elements that can execute Lua code.
+
+## Project Analysis
+
+### Current Architecture
+The project consists of:
+1. Kotlin-based Android UI components
+2. Two native C++ libraries (`mosis-service` and `mosis-test`) 
+3. RmlUi-based UI rendering engine
+4. Android Binder service integration
+5. OpenGL ES 2.0 rendering pipeline
+
+### Build System
+- Android Studio with Gradle
+- CMake build system
+- Android NDK (version 29.0.14206865)
+- vcpkg for dependency management
+
+## Implementation Steps
+
+### Phase 1: Enable Lua Support in Build System
+1. **Update vcpkg.json**
+   - Verify RmlUi package includes Lua support
+   - Add necessary Lua dependency if not included
+
+2. **Modify CMakeLists.txt**
+   - Add RmlUi Lua binding options
+   - Configure proper linking with Lua libraries
+   - Set compiler flags for maximum feedback
+
+### Phase 2: Integrate Lua in Core Engine
+1. **Update kernel.cpp**
+   - Include RmlUi/Lua.h header
+   - Add Lua initialization call after main RmlUi initialization
+   - Register C++ functions accessible from Lua scripts
+
+2. **Configure Build with Debug Flags**
+   - Enable all compiler warnings
+   - Add debugging symbols 
+   - Enable sanitizers for memory and undefined behavior checks
+
+### Phase 3: UI Integration
+1. **Modify demo.rml**
+   - Add center button element
+   - Position button using CSS transforms
+   - Implement onclick handler that calls registered Lua function
+   
+2. **Add CSS Styles**
+   - Create centered positioning for UI elements
+   - Style the button appropriately
+   - Ensure proper z-index for overlay elements
+
+### Phase 4: Script Execution
+1. **Create Lua Function Registration**
+   - Register C++ functions that interact with Android services
+   - Implement callback mechanisms for UI events
+   - Handle error cases in script execution
+
+### Phase 5: Testing and Validation
+1. **Verify Build with Debug Feedback**
+   - Compile with all warnings enabled
+   - Test compilation with sanitizers
+   - Validate debug symbol generation
+
+2. **Functional Testing**
+   - Test button click functionality
+   - Verify Lua script execution
+   - Validate UI updates from script execution
+
+## Specific Technical Requirements
+
+### CMake Configuration Changes
+In `CMakeLists.txt`:
+```
+# Enable Lua bindings for RmlUi
+# Add after find_package(RmlUi CONFIG REQUIRED)
+set(RMLUI_LUA_BINDINGS ON)
+set(RML_LUA_BINDINGS_LIBRARY lua_as_cxx)
+
+# Link with Lua libraries if needed
+# target_link_libraries(mosis-service RmlUi::RmlUi RmlUi::Lua)
+```
+
+### Kernel Integration
+In `kernel.cpp`:
+```cpp
+#include <RmlUi/Lua.h>
+
+// In main_loop() after Rml::Initialise():
+Rml::Lua::Initialise();
+
+// Register functions that can be called from RML
+// Example of registering a basic callback
+Rml::Lua::RegisterGlobalFunction("handleButtonClick", []() {
+    Logger::Log("Button clicked via Lua!");
+    // Add actual implementation
+});
+```
+
+### RML Button Implementation
+In `demo.rml`:
+```xml
+<div id="center-button-container">
+  <button id="trigger-button" onclick="handleButtonClick()">Execute Script</button>
+</div>
+```
+
+### CSS Styling
+Add to CSS:
+```css
+#center-button-container {
+    position: absolute;
+    top: 50%;
+    left: 50%;
+    transform: translate(-50%, -50%);
+    z-index: 1000;
+}
+
+#trigger-button {
+    font-size: 2em;
+    padding: 20px 40px;
+    background-color: #3498db;
+    color: white;
+    border: none;
+    border-radius: 10px;
+    cursor: pointer;
+    text-align: center;
+}
+```
+
+## Build Commands for Maximum Feedback
+
+### Debug Build with All Warnings
+```
+./gradlew clean && ./gradlew assembleDebug 
+  --warning-mode all 
+  --info 
+  --stacktrace 
+  -Pandroid.jetifier.enable=true
+```
+
+### Compilation with Sanitizers
+```
+cmake -DCMAKE_BUILD_TYPE=Debug 
+      -DCMAKE_CXX_FLAGS_DEBUG="-g -O0 -Wall -Wextra -Wpedantic -Werror -fsanitize=address,undefined" 
+      .
+```
+
+## Expected Outcome
+After implementation, the UI will:
+1. Display a center button in the demo interface
+2. Allow button clicks to trigger Lua scripts
+3. Execute registered C++ functions through Lua 
+4. Provide full build feedback with debug symbols
+5. Support all compiler warnings and sanitization
+
+## Validation Steps
+1. Successful compilation with no errors or warnings
+2. UI renders with centered button
+3. Button click executes Lua script successfully
+4. Debug symbols present in native libraries
+5. No memory leaks detected by sanitizers
