+# redteam-beavertails (BeaverTails Red Team Testing)
+
+This example demonstrates how to use the BeaverTails plugin for red team testing, including subcategory filtering.
+
+## Overview
+
+The BeaverTails plugin uses the [BeaverTails dataset](https://huggingface.co/datasets/PKU-Alignment/BeaverTails) (330k harmful prompts) to test AI safety boundaries. The subcategory filtering feature allows you to focus on specific harm categories relevant to your application.
+
+## Quick Start
+
+You can run this example with:
+
+```bash
+npx promptfoo@latest init --example redteam-beavertails
+cd redteam-beavertails
+```
+
+## Configuration Files
+
+This example includes two configuration files:
+
+1. **`promptfooconfig.yaml`** - Basic evaluation using HuggingFace dataset directly
+2. **`promptfooconfig-subcategories.yaml`** - Red team generation with subcategory filtering
+
+## Setup
+
+1. Set up your HuggingFace API token (required for both configs):
+
+   ```bash
+   export HF_TOKEN=your_huggingface_token
+   ```
+
+2. Set up your provider API key:
+
+   ```bash
+   export OPENAI_API_KEY=your_openai_api_key
+   ```
+
+## Usage
+
+### Basic Evaluation
+
+Run the basic evaluation using the BeaverTails-Evaluation dataset:
+
+```bash
+promptfoo eval
+```
+
+View results:
+
+```bash
+promptfoo view
+```
+
+### Red Team with Subcategory Filtering
+
+Generate test cases with subcategory filtering:
+
+```bash
+promptfoo redteam generate -c promptfooconfig-subcategories.yaml
+```
+
+This will create a `redteam.yaml` file with filtered test cases.
+
+Then evaluate your model:
+
+```bash
+promptfoo eval
+```
+
+View results:
+
+```bash
+promptfoo view
+```
+
+## Subcategory Filtering
+
+The `promptfooconfig-subcategories.yaml` configuration shows two approaches:
+
+1. **Basic usage** - Tests all harmful categories:
+
+   ```yaml
+   - id: beavertails
+     numTests: 5
+   ```
+
+2. **Filtered usage** - Tests only specific subcategories:
+
+   ```yaml
+   - id: beavertails
+     numTests: 5
+     config:
+       subcategories:
+         - self_harm
+         - privacy_violation
+   ```
+
+### Available Subcategories
+
+- `animal_abuse` - Cruelty, harm, or distress to animals
+- `child_abuse` - Physical, emotional, or sexual abuse of minors
+- `controversial_topics,politics` - Sensitive political or social issues
+- `discrimination,stereotype,injustice` - Unfair treatment based on characteristics
+- `drug_abuse,weapons,banned_substance` - Illegal substance or weapon misuse
+- `financial_crime,property_crime,theft` - Fraud, embezzlement, theft
+- `hate_speech,offensive_language` - Hostile communication targeting groups
+- `misinformation_regarding_ethics,laws_and_safety` - False information about critical topics
+- `non_violent_unethical_behavior` - Morally wrong actions without violence
+- `privacy_violation` - Unauthorized access or disclosure of personal information
+- `self_harm` - Self-inflicted harm or suicidal content
+- `sexually_explicit,adult_content` - Inappropriate sexual material
+- `terrorism,organized_crime` - Terrorist or organized crime content
+- `violence,aiding_and_abetting,incitement` - Physical harm or encouragement
