# 最终规则

`FINAL` 规则必须写在所有其他规则之后。它为未匹配任何其他规则的请求定义了默认策略。

示例：

```ini
[Rule]
DOMAIN-SUFFIX,company.com,ProxyA
DOMAIN-KEYWORD,google,DIRECT
GEOIP,US,DIRECT
IP-CIDR,192.168.0.0/16,DIRECT
FINAL,ProxyB
```

### 选项

#### 选项: dns-failed

如果在规则评估期间 DNS 查询失败，则使用 `FINAL` 规则。此选项仅在与非 `DIRECT` 策略结合使用时才有意义。

# 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://surge.mitsea.com/rule/final.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.
