## Execution Checklist

2. Clarify task type (chat, summarize, rewrite, extract).
3. Set safe defaults (`temperature`, `max_tokens`, `top_p`).
4. Return output plus key parameters used.

## Minimal Request Template

```bash
curl https://ark.cn-beijing.volces.com/api/v3/chat/completions \
  -H "Authorization: Bearer $ARK_API_KEY" \

  -d '{
    "model": "ep-xxxx",
    "messages": [{"role":"user","content":"请总结这段文本"}],

  }'
```
