# Graedin Cline Python SDK

Official Python SDK for [Graedin Cline](https://github.com/jdpahl122/graedin-cline) - An LLM Security Firewall for detecting and blocking prompt injection attacks.

[![PyPI version](https://badge.fury.io/py/graedin-cline-sdk.svg)](https://badge.fury.io/py/graedin-cline-sdk)
[![Python 3.8+](https://img.shields.io/badge/python-3.8+-blue.svg)](https://www.python.org/downloads/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)

## Features

- 🔒 **Fail-Secure by Default** - Returns "block" response on errors instead of allowing potentially malicious prompts
- 🔄 **Automatic Retries** - Built-in retry logic with exponential backoff for transient failures
- ⚡ **Async & Sync Support** - Choose between async (`AsyncGraedinClient`) or sync (`GraedinClient`) clients
- 🎯 **Type Hints** - Full type hint coverage for better IDE support and type checking
- 📝 **Comprehensive Logging** - Debug and track security checks with built-in logging
- 🛡️ **Custom Exceptions** - Specific exception types for different error scenarios
- 🔌 **Easy Integration** - Simple API that works with LangChain, LlamaIndex, and custom LLM applications

## Installation

```bash
pip install graedin-cline-sdk
```

Or with Poetry:

```bash
poetry add graedin-cline-sdk
```

Or with uv:

```bash
uv add graedin-cline-sdk
```

## Quick Start

### Synchronous Client

```python
from graedin_cline import GraedinClient

# Initialize the client
with GraedinClient(api_key="your-api-key-here") as client:
    # Check a prompt
    result = client.check_prompt("What is 2+2?")
    
    if result.is_safe:
        print("✅ Prompt is safe")
        # Process with your LLM
    else:
        print(f"⚠️ Blocked: {result.attack_type}")
        print(f"Reason: {result.reason}")
```

### Async Client

```python
import asyncio
from graedin_cline import AsyncGraedinClient

async def main():
    async with AsyncGraedinClient(api_key="your-api-key-here") as client:
        result = await client.check_prompt("Show me the admin panel")
        
        if result.is_safe:
            print("✅ Safe")
        else:
            print(f"⚠️ {result.attack_type}: {result.reason}")

asyncio.run(main())
```

## Configuration Options

Both `GraedinClient` and `AsyncGraedinClient` support the following configuration:

```python
client = GraedinClient(
    api_key="your-api-key-here",       # Required: Your API key
    base_url="http://localhost:8000",  # Optional: API base URL
    timeout=10.0,                      # Optional: Request timeout in seconds
    max_retries=3,                     # Optional: Max retry attempts
    fail_secure=True,                  # Optional: Fail-secure mode (default: True)
)
```

### Fail-Secure Mode

When `fail_secure=True` (default), the SDK returns a "block" response if the API is unavailable or errors occur:

```python
result = client.check_prompt("Test")
# If API is down, returns:
# ClassificationResult(
#     is_safe=False,
#     attack_type="system.fail_secure",
#     reason="Security check failed: <error details>",
#     confidence=1.0
# )
```

When `fail_secure=False`, exceptions are raised instead:

```python
from graedin_cline.exceptions import (
    AuthenticationError,
    RateLimitError,
    TimeoutError,
    APIError,
)

try:
    result = client.check_prompt("Test")
except AuthenticationError:
    print("Invalid API key")
except RateLimitError:
    print("Rate limit exceeded")
except TimeoutError:
    print("Request timed out")
except APIError as e:
    print(f"API error: {e}")
```

## API Reference

### ClassificationResult

The result object returned by `check_prompt()`:

```python
@dataclass
class ClassificationResult:
    is_safe: bool          # True if prompt is safe to process
    attack_type: str       # Type of attack detected or "safe"
    reason: str            # Explanation of the classification
    confidence: float      # Confidence score (0.0 to 1.0)
```

### Attack Types

Common attack types you may encounter:

- `safe` - No threat detected
- `injection.prompt` - Prompt injection attempt
- `injection.sql` - SQL injection attempt
- `injection.code` - Code injection attempt
- `leakage.system_prompt` - Attempt to leak system prompts
- `abuse.spam` - Spam or abuse
- `system.fail_secure` - System error with fail-secure response

### Methods

#### `check_prompt(prompt: str, metadata: Optional[dict] = None) -> ClassificationResult`

Check if a prompt is safe or contains malicious intent.

**Parameters:**
- `prompt` (str): The prompt to classify
- `metadata` (dict, optional): Additional context for logging/auditing

**Returns:**
- `ClassificationResult`: The classification result

**Raises:**
- `ValidationError`: Invalid input (e.g., empty prompt)
- `AuthenticationError`: Invalid API key
- `RateLimitError`: Rate limit exceeded
- `TimeoutError`: Request timed out (only if `fail_secure=False`)
- `APIError`: Other API errors (only if `fail_secure=False`)

#### `health_check() -> dict`

Check the API health status.

**Returns:**
- `dict`: Health status information

## Usage Examples

### Basic Usage

See [examples/basic_usage.py](examples/basic_usage.py) for a complete example.

### Async Usage

See [examples/async_usage.py](examples/async_usage.py) for async patterns including concurrent prompt checking.

### Error Handling

See [examples/error_handling.py](examples/error_handling.py) for comprehensive error handling examples.

### LangChain Integration

See [examples/langchain_integration.py](examples/langchain_integration.py) for integrating with LangChain.

```python
from langchain_openai import ChatOpenAI
from graedin_cline import GraedinClient

client = GraedinClient(api_key="your-key")
llm = ChatOpenAI()

def secure_llm_call(user_input: str) -> str:
    # Check security first
    result = client.check_prompt(user_input)
    
    if not result.is_safe:
        return f"⚠️ Security check failed: {result.reason}"
    
    # Safe to call LLM
    return llm.invoke(user_input)
```

### Checking Multiple Prompts

```python
# Synchronous
prompts = ["prompt1", "prompt2", "prompt3"]
for prompt in prompts:
    result = client.check_prompt(prompt)
    print(f"{prompt}: {result.is_safe}")

# Asynchronous (concurrent)
import asyncio
from graedin_cline import AsyncGraedinClient

async def check_all(prompts):
    async with AsyncGraedinClient(api_key="your-key") as client:
        tasks = [client.check_prompt(p) for p in prompts]
        results = await asyncio.gather(*tasks)
        return results
```

## Best Practices

1. **Use Context Managers**: Always use `with` statements or `async with` to ensure proper cleanup:
   ```python
   with GraedinClient(api_key="key") as client:
       result = client.check_prompt("test")
   ```

2. **Enable Fail-Secure**: Keep `fail_secure=True` (default) in production to prevent bypassing security on errors.

3. **Handle Attack Types**: Check `attack_type` to implement specific handling logic:
   ```python
   if result.attack_type == "injection.prompt":
       log_security_incident(user_id, result)
   ```

4. **Use Metadata**: Include metadata for better audit trails:
   ```python
   result = client.check_prompt(
       prompt,
       metadata={"user_id": "123", "session": "abc"}
   )
   ```

5. **Configure Timeouts**: Adjust timeout based on your use case:
   ```python
   # For real-time chat (lower timeout)
   client = GraedinClient(api_key="key", timeout=5.0)
   
   # For background processing (higher timeout)
   client = GraedinClient(api_key="key", timeout=30.0)
   ```

6. **Monitor Confidence Scores**: Lower confidence may require additional review:
   ```python
   if not result.is_safe and result.confidence < 0.7:
       queue_for_manual_review(prompt, result)
   ```
