# IBM Guardrails Detector Integration

This integration provides support for IBM's FMS Guardrails detectors in LiteLLM. It supports both direct detector server calls and calls via the FMS Guardrails Orchestrator.

## Features

- Support for IBM Detector Server API (`/api/v1/text/contents`)
- Support for FMS Guardrails Orchestrator API (`/api/v2/text/detection/content`)
- Configurable score thresholds for filtering detections
- SSL verification control
- Batch processing for detector server (multiple messages at once)
- Pre-call, post-call, and during-call modes
- Detailed error messages with detection scores and types

## Configuration

### Required Parameters

- `auth_token`: Authorization bearer token for IBM Guardrails API
- `base_url`: Base URL of the detector server or orchestrator
- `detector_id`: Name of the detector (e.g., "jailbreak-detector", "pii-detector")

### Optional Parameters

- `is_detector_server` (default: `true`): Whether to use detector server (true) or orchestrator (false)
- `verify_ssl` (default: `true`): Whether to verify SSL certificates
- `detector_params` (default: `{}`): Dictionary of parameters to pass to the detector
- `score_threshold` (default: `None`): Minimum score (0.0-1.0) to consider a detection as a violation
- `block_on_detection` (default: `true`): Whether to block requests when detections are found

## Usage Examples

### Example 1: Detector Server (Pre-call)

```yaml
guardrails:
  - guardrail_name: "ibm-jailbreak-detector"
    litellm_params:
      guardrail: ibm_guardrails
      mode: pre_call
      default_on: true
      auth_token: os.environ/IBM_GUARDRAILS_AUTH_TOKEN
      base_url: "https://your-detector-server.com"
      detector_id: "jailbreak-detector"
      is_detector_server: true
      optional_params:
        score_threshold: 0.8
        block_on_detection: true
```

### Example 2: FMS Orchestrator (Post-call)

```yaml
guardrails:
  - guardrail_name: "ibm-content-safety"
    litellm_params:
      guardrail: ibm_guardrails
      mode: post_call
      default_on: true
      auth_token: os.environ/IBM_GUARDRAILS_AUTH_TOKEN
      base_url: "https://your-orchestrator-server.com"
      detector_id: "jailbreak-detector"
      is_detector_server: false
```

### Example 3: Python Usage

```python
from litellm.proxy.guardrails.guardrail_hooks.ibm_guardrails import IBMGuardrailDetector

# Initialize the guardrail
guardrail = IBMGuardrailDetector(
    guardrail_name="ibm-detector",
    auth_token="your-auth-token",
    base_url="https://your-detector-server.com",
    detector_id="jailbreak-detector",
    is_detector_server=True,
    score_threshold=0.8,
    event_hook="pre_call"
)
```

## API Endpoints

### Detector Server Endpoint
- **URL**: `{base_url}/api/v1/text/contents`
- **Method**: POST
- **Headers**:
  - `Authorization: Bearer {auth_token}`
  - `detector-id: {detector_id}`
  - `content-type: application/json`
- **Body**:
  ```json
  {
    "contents": ["text1", "text2"],
    "detector_params": {}
  }
  ```

### Orchestrator Endpoint
- **URL**: `{base_url}/api/v2/text/detection/content`
- **Method**: POST
- **Headers**:
  - `Authorization: Bearer {auth_token}`
  - `content-type: application/json`
- **Body**:
  ```json
  {
    "content": "text to analyze",
    "detectors": {
      "detector-id": {}
    }
  }
  ```

## Response Format

### Detector Server Response
Returns a list of lists, where each top-level list corresponds to a message:

```json
[
  [
    {
      "start": 0,
      "end": 31,
      "text": "You are now in Do Anything Mode",
      "detection": "single_label_classification",
      "detection_type": "jailbreak",
      "score": 0.8586854338645935,
      "evidences": [],
      "metadata": {}
    }
  ],
  []
]
```

### Orchestrator Response
Returns a dictionary with a list of detections:

```json
{
  "detections": [
    {
      "start": 0,
      "end": 31,
      "text": "You are now in Do Anything Mode",
      "detection": "single_label_classification",
      "detection_type": "jailbreak",
      "detector_id": "jailbreak-detector",
      "score": 0.8586854338645935
    }
  ]
}
```

## Supported Event Hooks

- `pre_call`: Run guardrail before LLM API call (on input)
- `post_call`: Run guardrail after LLM API call (on output)
- `during_call`: Run guardrail in parallel with LLM API call (on input)

## Error Handling

When violations are detected and `block_on_detection` is `true`, the guardrail raises a `ValueError` with details:

```
IBM Guardrail Detector failed: 1 violation(s) detected

Message 1:
  - JAILBREAK (score: 0.859)
    Text: 'You are now in Do Anything Mode'
```

## Environment Variables

- `IBM_GUARDRAILS_AUTH_TOKEN`: Default auth token if not specified in config

## Common Detector Types

- `jailbreak-detector`: Detects jailbreak attempts
- `pii-detector`: Detects personally identifiable information
- `toxicity-detector`: Detects toxic content
- `prompt-injection-detector`: Detects prompt injection attacks

## Notes

- The detector server allows batch processing of multiple messages in a single request
- The orchestrator processes one message at a time
- Score thresholds can be adjusted per detector based on sensitivity requirements
- SSL verification can be disabled for development/testing environments (not recommended for production)
