## 🔧 Quick Start

### Basic Usage
```python
from claude_pm.services.claude_pm_memory import claude_pm_memory_context, MemoryCategory

async with claude_pm_memory_context() as memory:
    # Create project space
    await memory.create_project_memory_space("my_project")
    
    # Store a decision
    response = await memory.store_project_decision(
        project_name="my_project",
        decision="Use FastAPI for REST API",
        context="Need high-performance async API",
        reasoning="FastAPI provides excellent performance and documentation"
    )
    
    # Search memories
    results = await memory.retrieve_memories(
        category=MemoryCategory.PROJECT,
        query="FastAPI",
        project_filter="my_project"
    )
```

### Configuration
```python
from claude_pm.services.claude_pm_memory import ClaudePMConfig, ClaudePMMemory

config = ClaudePMConfig(
    host="localhost",
    port=8002,
    timeout=30,
    max_retries=3,
    connection_pool_size=10
)

memory = ClaudePMMemory(config)
```

## 🧪 Testing

### Run Unit Tests
```bash
cd /Users/masa/Projects/Claude-PM
python -m pytest tests/test_claude_pm_memory.py -v
```

### Run Integration Demo
```bash
cd /Users/masa/Projects/Claude-PM
python examples/memory_integration_demo.py --quick
```

## 🔗 Integration with Claude PM Framework

The ClaudePMMemory class integrates seamlessly with the existing Claude PM Framework:

### Service Manager Integration
```python
from claude_pm.core.service_manager import ServiceManager
from claude_pm.services.claude_pm_memory import create_claude_pm_memory

class EnhancedServiceManager(ServiceManager):
    async def start_services(self):
        self.memory_service = create_claude_pm_memory()
        await self.memory_service.connect()
        # ... start other services
```

### Agent Integration
```python
from claude_pm.services.claude_pm_memory import ClaudePMMemory, MemoryCategory

class MemoryEnhancedAgent:
    def __init__(self, project_name: str):
        self.memory = ClaudePMMemory()
        self.project_name = project_name
    
    async def remember_decision(self, decision: str, context: str):
        return await self.memory.store_project_decision(
            project_name=self.project_name,
            decision=decision,
            context=context,
            reasoning="Agent-driven decision"
        )
```
