## 🚀 Usage Examples

### Basic Agent Selection

```python
from framework.langgraph.memory_augmented_agents import create_agent_memory_manager

# Create memory manager
memory_manager = create_agent_memory_manager()

# Select optimal agent for a task
result = await memory_manager.select_optimal_agent(
    task_description="Implement user authentication system",
    complexity="standard",
    available_agents=["architect", "engineer", "qa"],
    strategy=AgentSelectionStrategy.HYBRID
)

print(f"Selected: {result.selected_agent} (confidence: {result.confidence:.2f})")
print(f"Reasoning: {result.reasoning}")
```

### Enhanced Workflow Execution

```python
from framework.langgraph.graphs.memory_augmented_task_graph import create_memory_augmented_task_graph

# Create memory-augmented task graph
task_graph = create_memory_augmented_task_graph()

# Execute task with memory enhancement
result = await task_graph.execute(
    task_description="Refactor legacy payment processing",
    context={"priority": "high", "security_critical": True},
    user_id="developer_123"
)

print(f"Task completed with status: {result['status']}")
print(f"Memory optimizations applied: {result.get('memory_optimizations', 0)}")
```

### Performance Monitoring

```python
from framework.langgraph.performance_tracker import create_performance_tracker, MetricType

# Create performance tracker
tracker = create_performance_tracker()

# Record agent execution
await tracker.record_execution_metrics(
    agent_id="engineer_001",
    agent_role="engineer",
    execution_time_ms=1500,
    success=True,
    confidence=0.85,
    memory_hit=True,
    patterns_applied=2,
    task_complexity="standard",
    task_type="implementation"
)

# Analyze trends
analysis = await tracker.analyze_performance_trends(time_window_hours=24)
print(f"Analyzed {len(analysis['agents'])} agents")

# Get top performers
top_performers = await tracker.get_top_performing_agents(
    limit=5,
    metric_type=MetricType.SUCCESS_RATE
)
```

# Set improvement thresholds
tracker.improvement_thresholds = {
    MetricType.SUCCESS_RATE: 0.10,      # 10% improvement threshold
    MetricType.EXECUTION_TIME: -0.15,   # 15% speed improvement
