# 失去的东西

“攒了好一阵子才买下戒指的……”\
我一边嘟囔着，一边在柜子里翻找。\
好像之前也有过类似的事。\
“知道我的项链放在哪里了吗？”\
“不知道。”\
“很贵呀，到底放哪儿了呢……”

“大家都在为了得到东西而努力，\
却很少为了不失去而努力呢。”\
你不知何时说出的这句话，让我如鲠在喉。

我把手伸进最里面的纸箱，\
翻出来的不是戒指，\
而是一张充满怀念的纸。\
那是我们还在一起时，\
你写给我的信。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://koi.aki-yzh.cn/hadaitainomonode/shi-qu-de-dong-xi.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
