SelectiveContextDemo.vue
|
||
选择性上下文保留演示
|
||
|
||
用途：
|
||
展示如何通过 "Pinning" (钉住) 机制来保护关键信息不被滑动窗口移除。
|
||
演示 System Prompt 和关键用户指令如何长期保留。
|
||
|
||
交互功能：
|
||
- 发送消息：添加新内容。
|
||
- 钉住/取消钉住：手动选择要保留的消息。
|
||
- 自动管理：演示当窗口满时，未钉住的消息优先被移除。

<strong>说明：</strong>
|
||
“选择性保留”就是：重要的就钉在黑板上，普通的让它自己滑走。
|
||
系统提示通常会永久钉住，用户的关键信息（比如名字、账号、重要偏好）也可以通过记忆模块或 RAG 钉在这里，避免被新对话挤掉。
