## Usage Examples

### Example 1: Todo Management

```python
from claude_force import AgentOrchestrator
from claude_force.models.todo import TodoItem, Priority

# Initialize
orchestrator = AgentOrchestrator()

# Add a todo
todo = TodoItem(
    action="Fix authentication bug",
    why_matters="Users cannot login after password reset",
    problem="Login endpoint returns 500 error",
    current_state="Password reset emails sent but login fails",
    desired_state="Users can login after password reset",
    success_criteria=[
        "Login works after password reset",
        "No 500 errors in logs"
    ],
    files=["src/auth/login.py:45-67"],
    priority=Priority.HIGH
)

success, similar = orchestrator.todos.add_todo(todo)

# Get todos
todos = orchestrator.todos.get_todos()
high_priority = orchestrator.todos.get_todos(filter_by={'priority': 'high'})

# Complete todo
orchestrator.todos.complete_todo(todo.id)

# Archive completed
archived = orchestrator.todos.archive_completed_todos()
```

### Example 2: Session Handoff

```python
from claude_force import AgentOrchestrator

orchestrator = AgentOrchestrator()

# Generate handoff
handoff = orchestrator.handoffs.generate_handoff()

# Save to file
path = orchestrator.handoffs.save_handoff(handoff)
print(f"Handoff saved to: {path}")

# Load previous handoff
previous = orchestrator.handoffs.load_latest_handoff()
if previous:
    print(f"Session: {previous.session_id}")
    print(f"Status: {previous.confidence_level.value}")
    print(f"Next steps: {previous.work_remaining.priority_1_critical}")
```

### Example 3: Meta-Prompting

```python
from claude_force import AgentOrchestrator
from claude_force.models.meta_prompt import MetaPromptRequest, MetaPromptConstraints

orchestrator = AgentOrchestrator()

# Create request
request = MetaPromptRequest(
    objective="Build user authentication with email verification",
    constraints=MetaPromptConstraints(
        budget_limit=5.00,
        timeline="60 min"
    )
)

# Generate workflow
response = orchestrator.meta_prompt.generate_workflow(request)

print(f"Refined Objective: {response.refined_objective}")
print(f"Workflow: {response.proposed_approach.workflow}")
print(f"Governance: {'PASSED' if response.governance_compliance.validation_status else 'FAILED'}")

if response.governance_compliance.validation_status:
    print(f"Success Criteria:")
    for criterion in response.success_criteria:
        print(f"  - {criterion}")
```

### Example 4: Using Slash Commands

```bash
# Todo management
/todos --add "Fix performance issue in ProductList"
/todos                    # List and select
/todos --complete 2       # Mark complete
/todos --archive          # Archive completed

# Session handoff
/handoff                  # Generate current session handoff
/handoff --load           # Load previous handoff
/handoff --auto           # Enable auto-handoffs every 2 hours

# Meta-prompting
/meta-prompt "Build authentication system"
/meta-prompt "Optimize database" --budget 2.00 --timeline "30 min"
```
