## Overview

This repository contains custom providers for Llama Stack, including:

- **Question Validity Shield**: Ensures queries are related to OpenShift/Ansible topics (It can be Configured for other Platforms).
- **Redaction Shield**: Automatically detects and redacts sensitive information from user messages
- **Additional safety and content filtering providers**

## Building and publishing

Manual procedure, assuming an existing PyPI API token available:

    ## Generate distribution archives to be uploaded into Python registry
    pdm run python -m build
    ## Upload distribution archives into Python registry
    pdm run python -m twine upload --repository ${PYTHON_REGISTRY} dist/*

## Features

###  Redaction Shield
- **Pattern-based redaction**: YAML-configurable regex patterns for flexible content filtering
- **Automatic detection**: Detects credit card numbers, API keys, tokens, passwords, and custom patterns

###  Question Validity Shield
- **Topic validation**: Ensures queries are related to specified topics (OpenShift/Ansible) (It can be configured for other Platforms)
- **LLM-powered classification**: Uses AI to determine query relevance
- **Customizable responses**: Configure custom messages for invalid queries

   pip install lightspeed_stack_providers
   ```
2. **Configure your run.yaml** (see Configuration section below)

## Configuration 

### 1. Register External Providers

Add to your `run.yaml` file:

```yaml
# External providers configuration
external_providers_dir: ${env.EXTERNAL_PROVIDERS_DIR:/providers.d}

# Changes in the providers

providers:
  safety:
  - provider_id: llama-guard
    provider_type: inline::llama-guard
    config:
      excluded_categories: []

# For Redaction shields

  - provider_id: lightspeed_redaction
    provider_type: inline::lightspeed_redaction
    config:
        case_sensitive: false
        rules:
          - pattern: "(?i)(password|passwd)[\\s:=]+[^\\s]+"
            replacement: "[REDACTED_PASSWORD]"
          
          - pattern: "(?i)(registry|image):\\s*([\\w\\d\\.-]+)(:[\\w\\d\\.-]+)?"
            replacement: "\\1: [REDACTED_IMAGE]"
          
          - pattern: "(?i)(url|endpoint):\\s*https?://[\\w\\.-]+(:\\d+)?(/[\\w\\d\\.-]*)*"
            replacement: "\\1: [REDACTED_URL]"

        
          - pattern: "\\b(?:\\d{1,3}\\.){3}\\d{1,3}\\b"
            replacement: "[REDACTED_IP]"

# Test the redaction shield
curl -X POST "http://localhost:8321/v1/safety/run-shield" \
  -H "Content-Type: application/json" \
  -d '{
    "shield_id": "redaction-shield",
    "messages": [
      {
        "role": "user",
        "content": "My API key is abc123xyz and password is secret456"
      }
    ]
  }'
```
### Adding New Providers

1. **Create provider directory**
   ```bash
   mkdir -p ./providers.d/inline/safety/
   curl -o ./providers.d/inline/safety/lightspeed_question_validity.yaml https://raw.githubusercontent.com/lightspeed-core/lightspeed-            providers/refs/heads/main/resources/external_providers/inline/safety/lightspeed_question_validity.yaml
   curl -o ./providers.d/inline/safety/lightspeed_question_validity.yaml https://raw.githubusercontent.com/lightspeed-core/lightspeed-            providers/refs/heads/main/resources/external_providers/inline/safety/lightspeed_redaction.yaml   
   ```
3. **Add external provider definition**
   ```yaml
   # resources/external_providers/your_provider.yaml
   module: lightspeed_stack_providers.providers.inline.safety.your_provider
   config_class: lightspeed_stack_providers.providers.inline.safety.your_provider.config.YourProviderConfig
