+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Ray.Di is a dependency injection and AOP (Aspect-Oriented Programming) framework for PHP inspired by Google Guice. It provides annotations-based dependency injection with support for AOP interceptors.
+
+## Core Architecture
+
+### Key Components
+- **AbstractModule**: Base class for defining dependency bindings. Modules are composed using `install()` and can be overridden using `override()`
+- **Injector**: Main entry point that manages the DI container and creates instances. Auto-registers generated proxy classes and handles untargeted bindings
+- **Bind**: Fluent API for creating bindings (`.to()`, `.toProvider()`, `.toInstance()`, `.in()`)
+- **Container**: Internal storage for all bindings and dependencies
+- **Annotations**: Located in `src/di/Di/` - includes `@Inject`, `@Named`, `@Assisted`, etc.
+
+### Directory Structure
+- `src/di/`: Core DI framework code
+- `src-deprecated/`: Legacy code maintained for compatibility  
+- `tests/di/`: Unit tests with extensive fake classes for testing
+- `demo/` and `demo-php8/`: Examples showing framework usage
+- Compiled proxy classes are cached in configurable temp directories
+
+## Development Commands
+
+### Testing
+```bash
+composer test              # Run PHPUnit tests
+composer coverage          # Generate test coverage with Xdebug
+composer pcov              # Generate coverage with PCOV (faster)
+```
+
+### Code Quality
+```bash
+composer cs                # Run PHP_CodeSniffer
+composer cs-fix            # Auto-fix coding standards
+composer sa                # Static analysis (Psalm + PHPStan)
+composer clean             # Clear analysis caches
+```
+
+### Build Pipeline
+```bash
+composer build             # Full build: cs + sa + pcov + metrics
+composer tests             # Quick check: cs + sa + test
+```
+
+### Analysis Tools
+```bash
+composer phpmd             # PHP Mess Detector
+composer metrics           # Generate code metrics
+composer baseline          # Update static analysis baselines
+```
+
+## Testing Strategy
+
+- Tests use extensive fake classes in `tests/di/Fake/` to simulate real-world scenarios
+- Supports both PHP 7.2+ and PHP 8+ with separate test suites
+- Cache files are automatically cleaned between test runs
+- AOP proxy generation is tested with temporary directories
+
+## Framework Patterns
+
+### Module Definition
+```php
+class MyModule extends AbstractModule
+{
+    protected function configure(): void
+    {
+        $this->bind(Interface::class)->to(Implementation::class);
+        $this->bind(Service::class)->toProvider(ServiceProvider::class);
+    }
+}
+```
+
+### Injection Usage
+```php
+$injector = new Injector(new MyModule());
+$instance = $injector->getInstance(Interface::class);
+```
+
+## Important Notes
+
+- Ray.Di generates proxy classes for AOP which are cached in temp directories
+- The framework supports both constructor and setter injection
+- All bindings are resolved at runtime with automatic proxy weaving for aspects
+- Multi-binding support allows collecting multiple implementations of the same interface
