## Usage Examples

### Basic Pipeline Execution

```python
from claude_pm.services.prompt_improvement_pipeline import PromptImprovementPipeline

# Initialize pipeline
pipeline = PromptImprovementPipeline()

# Run full pipeline
results = await pipeline.run_full_pipeline(
    agent_types=['Documentation', 'Engineer']
)

print(f"Generated {results.improvement_summary['total_improvements']} improvements")
```

### Targeted Improvement

```python
# Run targeted improvement for specific agent
results = await pipeline.run_targeted_improvement(
    agent_type='Documentation',
    specific_patterns=['format_error', 'incomplete_info']
)

print(f"Validated {results['improvements_validated']} improvements")
```

### A/B Testing

```python
from claude_pm.services.prompt_validator import compare_prompts

# Compare two prompts
comparison = await compare_prompts(
    prompt_a="Original prompt content",
    prompt_b="Improved prompt content",
    agent_type="Documentation"
)

print(f"Winner: {comparison['winner']}")
print(f"Confidence: {comparison['confidence_level']:.2f}")

```python
from claude_pm.services.prompt_template_manager import PromptTemplateManager

manager = PromptTemplateManager()

# Create template
template = await manager.create_template(
    template_id="doc_agent_v2",
    content="Enhanced documentation prompt",
    template_type=TemplateType.AGENT_PROMPT,
