-# AGENTS.md - Aurora Rendering Engine
-
-## Project Overview
-Aurora Rendering Engine (ARE) is a high-performance path tracing library in C++ developed by NanoEra Studio. It provides a rendering framework using OpenGL 4.3 with support for GPU-accelerated ray tracing, BVH acceleration, and denoising.
-
-## Build Commands
-
-### Standard Build
-```bash
-mkdir build && cd build
-cmake ..
-cmake --build .
-```
-
-### Build Types
-- **Debug**: `cmake -DCMAKE_BUILD_TYPE=Debug ..`
-- **Release**: `cmake -DCMAKE_BUILD_TYPE=Release ..` (default)
-
-### Running Examples
-The main example is the Cornell Box demo:
-```bash
-./examples/cornell_box
-```
-
-### Testing
-This project currently has **no built-in unit tests**. Testing is performed manually by running the example executables. There are no test-specific build targets or test frameworks configured.
-
-### Linting/Code Formatting
-- **Format**: Use `.clang-format` configuration in project root
-  ```bash
-  clang-format -i src/*.cpp include/**/*.h
-  ```
-- **Clangd**: IDE integration via `.clangd` file (C++20, includes paths configured)
-
-## Code Style Guidelines
-
-### General Conventions
-- **C++ Standard**: C++17 (project CMake), C++20 (clangd for IDE)
-- **Indentation**: Tabs (see `.clang-format`: `UseTab: Always`)
-- **Line Length**: Unlimited (`ColumnLimit: 0`)
-- **Brace Style**: Attach (see `.clang-format`: `BreakBeforeBraces: Attach`)
-
-### File Organization
-- **Headers**: `include/` - Public API
-- **Source**: `src/` - Implementation
-- **Include format**: `#include "path/to/header.h"` (quotes for project headers)
-
-### Naming Conventions
-- **Classes**: `PascalCase` (e.g., `Renderer`, `Scene`)
-- **Functions**: `PascalCase` (e.g., `initialize()`, `render()`)
-- **Member variables**: `snake_case_` with trailing underscore (e.g., `config_`, `frame_count_`)
-- **Types (aliases)**: `PascalCase` (e.g., `Vec3`, `Mat4`, `TextureHandle`)
-- **Enums**: `PascalCase` with `k` prefix for values (e.g., `LogLevel::ARE_LOG_INFO`)
-
-### Header Guards
-```cpp
-#ifndef ARE_INCLUDE_PATH_TO_FILENAME_H
-#define ARE_INCLUDE_PATH_TO_FILENAME_H
-// ... content ...
-#endif // ARE_INCLUDE_PATH_TO_FILENAME_H
-```
-
-### Namespace
-- All code lives in `are` namespace
-- Namespace closing comment: `} // namespace are`
-
-### Imports/Includes Order
-1. Corresponding header (for .cpp files)
-2. Project headers (alphabetically within group)
-3. External library headers (e.g., `<glm/glm.hpp>`, `<glad/glad.h>`)
-4. Standard library headers
-
-### Comments
-- Use Doxygen-style `/** */` or `/* */` for function documentation
-- Brief descriptions in header files, implementation details in .cpp
-- Avoid unnecessary inline comments
-
-### Error Handling
-- Use `ARE_LOG_ERROR()`, `ARE_LOG_WARN()`, `ARE_LOG_CRITICAL()` macros
-- Return `false` on failure, `true` on success
-- Check initialization states before operations
-- Log with context: `"Failed to initialize X"`
-
-### Smart Pointers
-- Use `std::unique_ptr` for exclusive ownership
-- Use `std::shared_ptr` for shared ownership
-- Avoid raw `new`/`delete`
-
-### GLM Types
-Use GLM for all math types:
-```cpp
-using Vec2 = glm::vec2;
-using Vec3 = glm::vec3;
-using Vec4 = glm::vec4;
-using Mat3 = glm::mat3;
-using Mat4 = glm::mat4;
-```
-
-### OpenGL Resources
-- Follow OpenGL best practices
-- Check OpenGL errors during development (debug builds)
-- Clean up resources in destructors or `shutdown()` methods
