    searxng_url: ""            # SearXNG instance URL (or use SEARXNG_URL env var)
```

## Interaction Settings

### Customizing the Bot Name

The `mention_prefix` controls what trigger the bot responds to. You can change it to any name you prefer:

```yaml
interaction:
  mention_prefix: "@bartender"  # Users will type @bartender to invoke the bot
```

**Important:** When changing the bot name, you must also update the workflow files:

1. Edit `.github/workflows/ai-comment-reply.yml` and `ai-chat.yml` (for GitHub)
2. Edit `.gitea/workflows/ai-comment-reply.yml` and `ai-chat.yml` (for Gitea)
3. Change the `if:` condition to match your new prefix:
   ```yaml
   if: contains(github.event.comment.body, '@bartender')
   ```

**Example bot names:**
- `@codebot` - Default, generic
- `@bartender` - Friendly, conversational
- `@uni` - Short, quick to type
- `@joey` - Personal assistant
- `@codebot` - Technical focus

```yaml
interaction:
  respond_to_mentions: true
  mention_prefix: "@codebot"
  commands:
    - explain      # Explain code/issue
    - suggest      # Suggest solutions
    - security     # Run security check
    - summarize    # Summarize content
```

## Label Mappings

```yaml
labels:
  priority:
    high: "priority: high"
    medium: "priority: medium"
    low: "priority: low"
  type:
    bug: "type: bug"
    feature: "type: feature"
    question: "type: question"
    docs: "type: documentation"
  status:
    ai_approved: "ai-approved"
    ai_changes_required: "ai-changes-required"
    ai_reviewed: "ai-reviewed"
```

  audit_path: "/var/log/ai-review/"
  metrics_enabled: true
  rate_limit:
    requests_per_minute: 30

```

## Security Configuration

```yaml

  enabled: true
  fail_on_high: true
  rules_file: "security/security_rules.yml"  # Custom rules
