# Python API Examples

Executable examples demonstrating how to use the claude-force Python package programmatically.

## Prerequisites

1. **Install claude-force**:
   ```bash
   cd /path/to/claude-force
   python3 -m venv venv
   source venv/bin/activate
   pip install -e .
   ```

2. **Set API key**:
   ```bash
   export ANTHROPIC_API_KEY='your-api-key-here'
   ```

## Examples

### 1. Simple Agent (`01_simple_agent.py`)

Run a single agent to review code for security issues.

**Usage**:
```bash
python3 examples/python/01_simple_agent.py
```

**What it demonstrates**:
- Initializing the AgentOrchestrator
- Running a single agent (code-reviewer)
- Handling results and errors
- Proper exit codes

---

### 2. Workflow Example (`02_workflow_example.py`)

Run a complete multi-agent workflow (bug-fix).

**Usage**:
```bash
python3 examples/python/02_workflow_example.py
```

**What it demonstrates**:
- Listing available workflows
- Running multi-agent workflows
- Passing output between agents
- Workflow execution summary

---

### 3. Batch Processing (`03_batch_processing.py`)

Process multiple files/tasks in a loop.

**Usage**:
```bash
python3 examples/python/03_batch_processing.py
```

**What it demonstrates**:
- Processing multiple items
- Progress tracking

---

### 5. Performance Tracking (`05_performance_tracking.py`) ⭐ P1 Enhancement

Built-in performance monitoring and cost tracking.

**Usage**:
```bash
python3 examples/python/05_performance_tracking.py
```

**What it demonstrates**:
- Automatic performance tracking
- Token usage monitoring
- Cost estimation
- Per-agent statistics
- Cost breakdown visualizations

## Common Patterns

### Error Handling

```python
try:
    result = orchestrator.run_agent(...)
    if result.success:
        print(result.output)
    else:
        print(f"Errors: {result.errors}")
except KeyboardInterrupt:
    sys.exit(130)
except Exception as e:
    print(f"Error: {e}")
    sys.exit(1)
```

### API Key Check

```python
api_key = os.getenv("ANTHROPIC_API_KEY")
if not api_key:
    print("❌ Error: ANTHROPIC_API_KEY not set")
    sys.exit(1)
```

---

## Customization

### Change Model

```python
result = orchestrator.run_agent(
    agent_name='code-reviewer',
    task=task,
    model='claude-3-5-sonnet-20241022',
    max_tokens=4096,
    temperature=0.3
)
```

### Adjust Temperature

```python
temperature=0.0  # Most consistent
temperature=0.5  # Balanced
temperature=1.0  # Most creative
```

---

## Troubleshooting

### "ModuleNotFoundError: No module named 'claude_force'"

**Solution**: Install the package:
```bash
pip install -e .
```

### "API key required"

**Solution**: Set your API key:
```bash
export ANTHROPIC_API_KEY='your-api-key'
```
