# 高级玩法 — 节点引用

## 什么是节点

节点是 Flowith 画布中的最小单位。每一个 AI 回复，每一个你的输入，都是一个节点。

## 如何使用变量节点

变量节点引用适用于频繁改变的内容（比如翻译中需要翻译的文本）。

### 纯文本

**插入节点**

1. 点击左上角工具栏里 「变量节点」 按钮并拖拽到画布中
2. 修改节点的名字
3. 输入内容

**引用节点**

1. 将光标移动到需要插入处
2. 点击画布下方的圆形按钮
3. 选择 「引用其他节点内容」
4. 点击你所要引用的节点

# 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://doc.flowith.io/cn/flowith-normal/gao-ji-wan-fa-jie-dian-yin-yong.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.
