## 简介
该 **护栏选项卡** 提供了一个强大的控制界面，用于定义你的角色在伦理和话题上的边界，防止偏题或不当回复。通过在“Instructions”字段中输入具体约束并开启自定义护栏，你可以确保你的 AI 角色以安全、专业的方式回应，并严格符合你预期的品牌语调。
## 主要功能和部分
### 1. 自定义护栏开关
此切换按钮相当于总开关，用于启用或停用你的角色安全监管。启用后，它会强制 AI 角色优先遵循你指定的行为规则，而不是其通用对话逻辑。
### 2. 护栏指令
此文本字段允许你使用最多 7,500 个词来定义明确的安全规则和回复边界。你可以在这里输入诸如“不要谈论政治”之类的限制，以确保角色保持专业并围绕主题展开。
## 示例
此示例展示了你如何在 Convai Playground 中为你的 AI 角色实施护栏。
