This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

dsh-history-mirror-plugin

DeepSeek Harness Web 客户端插件：在会话标题栏添加“历史”按钮，将当前会话内容镜像到右侧详情栏，并提供独立滚动位置。

> DeepSeek Harness Web plugin that mirrors the current conversation into a scrollable right-side history panel.

核心体验： 中间会话保持在最新消息和输入框，右侧历史镜像可以独立向上滚动；回看上文后，无需再把主会话滚回底部。

交互

  • 中间会话保持当前输入和滚动位置。
  • 右侧复用中间会话已经渲染的 DOM 和原生样式，因此代码块、工具调用、图片等保持原来的外观。
  • 新消息和流式输出会同步到右侧。
  • 右侧滚动不会带动中间会话。
  • 点击右侧历史中的 HTTP/HTTPS 链接会切换到“网页”标签。

安全设计

  • 不读取或上传 API Key、Cookie、Local Storage、Session Storage 或环境变量。
  • 不访问本地文件系统，不执行系统命令，不创建后台服务。
  • 不调用 fetch、XHR、WebSocket 或遥测接口。
  • 会话镜像只存在于当前浏览器页面内；同步时会移除脚本、iframe、表单、object、embed、meta、link 和 base 元素。
  • 只接受 http:// 与 https:// 网页链接。网页预览使用无 allow-same-origin、无顶层导航权限的沙箱 iframe，并使用 no-referrer。

安装

从 GitHub 安装

npx @deepseek-ai/dsh plugin --profile web add github:xiaoyanjin15-ux/dsh-history-mirror-plugin
npx @deepseek-ai/dsh web

从本地源码安装

先停止正在运行的 DSH Web，再在本目录的上一级执行：

npx @deepseek-ai/dsh plugin --profile web add file:./dsh-history-mirror-plugin
npx @deepseek-ai/dsh web

浏览器刷新后，打开任意非空会话，点击会话标题栏右侧的“历史”。

当前边界

  • 右侧复制的是浏览器当前已加载的会话窗口；尚未由 Harness 加载的更早记录不会凭空出现。
  • 部分网站禁止 iframe 嵌入或无法在受限沙箱中运行，网页标签可能显示网站自身的拒绝页面。
  • 插件接管当前版本的 details 单槽位；启用时，原生工具详情面板会被历史面板替代。禁用或移除本插件即可恢复原生工具详情。
