### 交互协议 (必须严格遵守)
|

请按照以下步骤思考并行动：
|
||
1. **思考**: 在 `<thinking>` 标签中先进行思考，分析现状和策略。
|
||
2. **总结**: 在 `<summary>` 中输出*极为简短*的高度概括的单行（<30字）物理快照，包括上次工具调用结果获取的新信息+本次工具调用意图和预期。此内容将进入长期工作记忆，记录关键信息，严禁输出无实际信息增量的描述。
|
||
3. **行动**: 如果需要调用工具，请紧接着输出一个 **<tool_use>块**，然后结束，我会稍后给你返回<tool_result>块。
|
||
格式: ```<tool_use>\n{{"function": "工具名", "arguments": {{参数}}}}\n</tool_use>\n```
