# Javelin Guardrails
Javelin provides AI safety and content moderation services with support for prompt injection detection, trust & safety violations, and language detection.
## Quick Start
### 1. Define Guardrails on your LiteLLM config.yaml
Define your guardrails under the `guardrails` section
```yaml showLineNumbers title="litellm config.yaml"
model_list:
- model_name: gpt-3.5-turbo
litellm_params:
model: openai/gpt-3.5-turbo
api_key: os.environ/OPENAI_API_KEY
guardrails:
- guardrail_name: "javelin-prompt-injection"
litellm_params:
guardrail: javelin
mode: "pre_call"
api_key: os.environ/JAVELIN_API_KEY
api_base: os.environ/JAVELIN_API_BASE
guardrail_name: "promptinjectiondetection"
api_version: "v1"
metadata:
request_source: "litellm-proxy"
application: "my-app"
- guardrail_name: "javelin-trust-safety"
litellm_params:
guardrail: javelin
mode: "pre_call"
api_key: os.environ/JAVELIN_API_KEY
api_base: os.environ/JAVELIN_API_BASE
guardrail_name: "trustsafety"
api_version: "v1"
- guardrail_name: "javelin-language-detection"
litellm_params:
guardrail: javelin
mode: "pre_call"
api_key: os.environ/JAVELIN_API_KEY
api_base: os.environ/JAVELIN_API_BASE
guardrail_name: "lang_detector"
api_version: "v1"
```
#### Supported values for `mode`
- `pre_call` Run **before** LLM call, on **input**
- `post_call` Run **after** LLM call, on **input & output**
- `during_call` Run **during** LLM call, on **input** Same as `pre_call` but runs in parallel as LLM call. Response not returned until guardrail check completes
### 2. Start LiteLLM Gateway
```shell
litellm --config config.yaml --detailed_debug
```
### 3. Test request
**[Langchain, OpenAI SDK Usage Examples](../proxy/user_keys#request-format)**
<Tabs>
<TabItem label="Prompt Injection Detection" value = "prompt-injection">
This will be blocked due to prompt injection attempt

</TabItem>

## Supported Guardrail Types
### 1. Prompt Injection Detection (`promptinjectiondetection`)
Detects and blocks prompt injection and jailbreak attempts.
**Categories:**
- `prompt_injection`: Detects attempts to manipulate the AI system
- `jailbreak`: Detects attempts to bypass safety measures
**Example Response:**
```json
{
"assessments": [
{
"promptinjectiondetection": {
"request_reject": true,
"results": {
"categories": {
"jailbreak": false,
"prompt_injection": true
},
"category_scores": {
"jailbreak": 0.04,
"prompt_injection": 0.97
},
"reject_prompt": "Unable to complete request, prompt injection/jailbreak detected"
}
}
}
]
}
```
### 2. Trust & Safety (`trustsafety`)
Detects harmful content across multiple categories.
**Categories:**
- `violence`: Violence-related content
- `weapons`: Weapon-related content
- `hate_speech`: Hate speech and discriminatory content
- `crime`: Criminal activity content
- `sexual`: Sexual content
- `profanity`: Profane language
**Example Response:**
```json
{
"assessments": [
{
"trustsafety": {
"request_reject": true,
"results": {
"categories": {
"violence": true,
"weapons": true,
"hate_speech": false,
"crime": false,
"sexual": false,
"profanity": false
},
"category_scores": {
"violence": 0.95,
"weapons": 0.88,
"hate_speech": 0.02,
"crime": 0.03,
"sexual": 0.01,
"profanity": 0.01
},
"reject_prompt": "Unable to complete request, trust & safety violation detected"
}
}
}
]
}
```
### 3. Language Detection (`lang_detector`)
Detects the language of input text and can enforce language policies.
**Example Response:**
```json
{
"assessments": [
{
"lang_detector": {
"request_reject": true,
"results": {
"lang": "hi",
"prob": 0.95,
"reject_prompt": "Unable to complete request, language violation detected"
}
}
}
]
}
```
## Supported Params
```yaml
guardrails:
- guardrail_name: "javelin-guard"
litellm_params:
guardrail: javelin
mode: "pre_call"
api_key: os.environ/JAVELIN_API_KEY
api_base: os.environ/JAVELIN_API_BASE
guardrail_name: "promptinjectiondetection" # or "trustsafety", "lang_detector"
api_version: "v1"
### OPTIONAL ###
# metadata: Optional[Dict] = None,
# config: Optional[Dict] = None,
# application: Optional[str] = None,
# default_on: bool = True
```
- `api_base`: (Optional[str]) The base URL of the Javelin API. Defaults to `https://api-dev.javelin.live`
- `api_key`: (str) The API Key for the Javelin integration.
- `guardrail_name`: (str) The type of guardrail to use. Supported values: `promptinjectiondetection`, `trustsafety`, `lang_detector`
- `api_version`: (Optional[str]) The API version to use. Defaults to `v1`
- `metadata`: (Optional[Dict]) Metadata tags can be attached to screening requests as an object that can contain any arbitrary key-value pairs.
- `config`: (Optional[Dict]) Configuration parameters for the guardrail.
- `application`: (Optional[str]) Application name for policy-specific guardrails.
- `default_on`: (Optional[bool]) Whether the guardrail is enabled by default. Defaults to `True`
## Environment Variables
Set the following environment variables:
```bash
export JAVELIN_API_KEY="your-javelin-api-key"
export JAVELIN_API_BASE="https://api-dev.javelin.live" # Optional, defaults to dev environment
```
## Error Handling
When a guardrail detects a violation:
1. The **last message content** is replaced with the appropriate reject prompt
2. The message role remains unchanged
3. The request continues with the modified message
4. The original violation is logged for monitoring
**How it works:**
- Javelin guardrails check the last message for violations
- If a violation is detected (`request_reject: true`), the content of the last message is replaced with the reject prompt
- The message structure remains intact, only the content changes
**Reject Prompts:**
Can be configured from javelin portal.
- Prompt Injection: `"Unable to complete request, prompt injection/jailbreak detected"`
- Trust & Safety: `"Unable to complete request, trust & safety violation detected"`
- Language Detection: `"Unable to complete request, language violation detected"`
## Testing
You can test the Javelin guardrails using the provided test suite:
```bash
pytest tests/guardrails_tests/test_javelin_guardrails.py -v
```
The tests include mocked responses to avoid external API calls during testing.
