Core Features

1. Interactive Chat

Start a persistent chat session:

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:

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:

# 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:

dbclaw tokens "Your text here"

SDK usage:

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

---

5. Vision / Image Analysis

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

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' }

Troubleshooting

"dbclaw: command not found"

Windows:

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

macOS/Linux:

source ~/.zshrc
# or
source ~/.bash_profile

---

"API Key not found"

Verify the API key is set:

# 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:

dbclaw models

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

---

Network / Connection Timeout

# 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:

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

Check network connection:

ping ark.volcengine.com

---

Advanced Usage

Batch Processing

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

Integration with Other Tools

# 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)

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

---

Rust Integration

Embed in Your Project

Add to Cargo.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

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:

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

✅ Use environment variables:

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

2. Rate Limiting

Implement backoff for production:

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:

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