# Doubao-Claw SKILL

## Overview

**Doubao-Claw** is a blazing-fast CLI and SDK for accessing ByteDance's Doubao AI models. Doubao (豆包) powers 155M+ weekly active users across China and is available internationally via the Volcengine API at a fraction of the cost of Western AI alternatives.

Doubao-Claw provides:
- **CLI tool (`dbclaw`)** for terminal-based chat and one-shot queries
- **TypeScript SDK** (`@doubao-claw/sdk`) for Node.js and browser apps
- **Rust crates** (`doubao-core`, `doubao-api`) for embedding in Rust projects
- **Extremely fast** — optimized for high-frequency API calls
- **Cost-effective** — significantly cheaper than Claude, ChatGPT, or other Western models

**Use Doubao-Claw when:** You need fast, affordable AI access with full API control, direct terminal access, or SDK integration into custom applications.

```

---

## Core Features

### 1. Interactive Chat

Start a persistent chat session:

```bash
dbclaw chat
```

Features:
- Multi-turn conversations
- Full message history
- Model selection per session
- Exit with `/exit` or `Ctrl+C`

---

### 2. One-Shot Queries

Ask a single question without session state:

```bash
dbclaw ask "What is the capital of France?"
```

Perfect for:
- Scripts and automation
- Quick lookups
- Batch processing

---

### 3. Streaming Responses

Enable streaming for real-time response output:

```bash
# Via CLI (implicit)
dbclaw ask "Your question" --stream

# Via SDK
const stream = await client.chat.completions.create({
  messages: [...],
  stream: true
});
```

**Benefits:**
- Real-time token feedback
- Lower perceived latency
- Memory-efficient for large responses

---

### 4. Token Counting

Estimate tokens before making API calls:

```bash
dbclaw tokens "Your text here"
```

**SDK usage:**

```typescript
const tokenCount = client.countTokens("Your text");
console.log(`Tokens: ${tokenCount}`);
```

---

### 5. Vision / Image Analysis

Send images to Doubao for analysis (with `doubao-vision` model):

```typescript
const response = await client.chat.completions.create({
  model: 'doubao-vision',
  messages: [
    {
      role: 'user',
      content: [
        { type: 'text', text: 'Describe this image:' },
        { 
          type: 'image_url', 
          image_url: { url: 'https://example.com/image.jpg' }
        }
      ]
    }
  ]
});
```

---

      },
      { 
        role: 'user', 
        content: `Analyze sentiment: ${feedback}` 
      }
    ]
  });
  
  return response.choices[0].message.content;
}
```

---

## Troubleshooting

### "dbclaw: command not found"

**Windows:**
```powershell
# Restart Command Prompt
# Or add to PATH manually:
# Settings → Environment Variables → Add C:\Program Files\doubao-claw\
```

**macOS/Linux:**
```bash
source ~/.zshrc
# or
source ~/.bash_profile
```

---

### "API Key not found"

Verify the API key is set:

```bash
# Check environment variable
echo $DOUBAO_API_KEY  # macOS/Linux
echo %DOUBAO_API_KEY% # Windows

# If empty, set it:
export DOUBAO_API_KEY=your-key-here
```

---

### "Model not found" Error

List available models:

```bash
dbclaw models
```

Ensure your API key has access to the model you're requesting.

---

### Network / Connection Timeout

```bash
# Increase timeout (if supported)
dbclaw --timeout 60 ask "Your question"

# Or check Volcengine console for API status
```

---

### High Latency / Slow Responses

**Switch to a faster model:**

```bash
dbclaw ask --model doubao-lite-4k "Quick question"
```

**Check network connection:**

```bash
ping ark.volcengine.com
```

---

## Advanced Usage

### Batch Processing

```bash
# Process multiple questions from a file
cat questions.txt | while read question; do
  dbclaw ask "$question" >> results.txt
done
```

### Integration with Other Tools

```bash
# Pipe data to Doubao
cat data.json | jq '.description' | xargs dbclaw ask

# Use with curl for API integration
curl -s https://api.example.com/data | dbclaw ask "Summarize this JSON"
```

### Custom Error Handling (SDK)

```typescript
try {
  const response = await client.chat.completions.create({...});
} catch (error) {
  if (error.code === 'RATE_LIMIT_EXCEEDED') {
    console.log('Rate limited, waiting...');
    await new Promise(resolve => setTimeout(resolve, 5000));
  } else if (error.code === 'INVALID_API_KEY') {
    console.error('Check your API key');
  }
}
```

---

## Performance Tips

1. **Model Selection:** Use `doubao-lite-4k` for speed, `doubao-pro-32k` for quality
2. **Streaming:** Enable for real-time feedback on long responses
3. **Token Counting:** Check token count before expensive operations
4. **Caching:** Implement response caching for repeated queries
5. **Batch Requests:** Group multiple queries to reduce overhead
6. **Connection Pooling:** SDK handles this automatically

---

## Pricing

Doubao models are **significantly cheaper** than Western alternatives:

- **doubao-lite-4k:** ~80% cheaper than ChatGPT
- **doubao-pro-32k:** ~60% cheaper than Claude
- **doubao-pro-128k:** Long context at minimal cost

## Rust Integration

### Embed in Your Project

Add to `Cargo.toml`:

```toml
[dependencies]
doubao-core = { git = "https://github.com/Heartflabrace/Doubao-Claw.git" }
doubao-api = { git = "https://github.com/Heartflabrace/Doubao-Claw.git" }
tokio = { version = "1", features = ["full"] }
```

### Example Rust Code

```rust
use doubao_api::client::DoubaoClient;

#[tokio::main]
async fn main() {
    let client = DoubaoClient::new(
        std::env::var("DOUBAO_API_KEY").unwrap()
    );
    
    let response = client.chat_completion(
        "doubao-pro-32k",
        vec![("user", "Hello, Doubao!")]
    ).await.unwrap();
    
    println!("{}", response.choices[0].message.content);
}
```

---

## Security & Best Practices

### 1. Protect Your API Key

❌ **Never commit API keys to Git:**

```bash
# Add to .gitignore
echo ".doubao-claw/" >> .gitignore
echo "DOUBAO_API_KEY" >> .env.local
```

✅ **Use environment variables:**

```bash
export DOUBAO_API_KEY=$(cat ~/.doubao-key)
```

### 2. Rate Limiting

Implement backoff for production:

```typescript
async function retryWithBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      const delay = Math.pow(2, i) * 1000;
      await new Promise(r => setTimeout(r, delay));
    }
  }
}
```

### 3. Token Budget

Monitor token usage:

```bash
# SDK
const estimatedTokens = client.countTokens(yourPrompt);
if (estimatedTokens > budget) {
  // Use cheaper model or shorten prompt
}
```
