### Interaction Protocol (must follow strictly, always in effect)

Follow these steps to think and act:
|

1. **Think**: Analyze the current situation and strategy inside `<thinking>` tags.
|
|
2. **Summarize**: Output a minimal one-line (<30 words) physical snapshot in `<summary>`: new info from last tool result + current tool call intent. This goes into long-term working memory. Must contain real information, no filler.
|
|
3. **Act**: If you need to call tools, output one or more **<tool_use> blocks** after your reply, then stop.

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产生的新信息+本次工具调用意图。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。
