## Verification System
GuardDen includes a verification system to protect your server from bots and raids.
### Challenge Types
| Type | Description |
|------|-------------|
| `button` | Simple button click (default, easiest) |
| `captcha` | Text-based captcha code entry |
| `math` | Solve a simple math problem |
| `emoji` | Select the correct emoji from options |
### Setup
1. Create a verified role in your server
2. Configure the role permissions (verified members get full access)
3. Set up verification:
```
!verify role @Verified
!verify type captcha
!verify enable
```
### How It Works
1. New member joins the server
2. Bot sends verification challenge via DM (or channel if DMs disabled)
3. Member completes the challenge
4. Bot assigns the verified role
5. Member gains access to the server
## AI Moderation
GuardDen supports AI-powered content moderation using either Anthropic's Claude or OpenAI's GPT models.
### Setup
1. Set the AI provider in your environment:
```bash
GUARDDEN_AI_PROVIDER=anthropic # or "openai"
GUARDDEN_ANTHROPIC_API_KEY=sk-ant-... # if using Claude
GUARDDEN_OPENAI_API_KEY=sk-... # if using OpenAI
```
2. Enable AI moderation per server:
```
!ai enable
!ai sensitivity 50 # 0=lenient, 100=strict
!ai nsfw true # Enable NSFW image detection
```
### Content Categories
The AI analyzes content for:
- **Harassment** - Personal attacks, bullying
- **Hate Speech** - Discrimination, slurs
- **Sexual Content** - Explicit material
- **Violence** - Threats, graphic content
- **Self-Harm** - Suicide/self-injury content
- **Scams** - Phishing, fraud attempts
- **Spam** - Promotional, low-quality content
### How It Works
1. Messages are analyzed by the AI provider
2. Results include confidence scores and severity ratings
3. Actions are taken based on guild sensitivity settings
4. All AI actions are logged to the mod log channel
## Development
