Install

Start with a prompt that asks an agent to read the 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 read the page and repository first.

Do not install anything yet. Read this DeepSeek Harness plugin and explain what it does, which files, networks, or credentials it can access, and how to install and remove it.

dsh-selection-followup

选中 DSH 聊天回复中的任意文字,浮出「追问 / 复制」气泡: 一键把选中内容作为引用填入输入框,问题由你自己输入;或一键复制。

安装

dsh plugin --profile web add "github:zzx-dear/dsh-selection-followup"
# 或本地开发:
dsh plugin --profile web add link:/path/to/dsh-selection-followup

重启 dsh web 后生效。

用法

1. 在任意聊天回复里用鼠标选中一段文字 2. 选区下方浮出气泡: - 追问 — 把 「选中内容」 填入输入框并聚焦,你在引用后面输入你的问题,回车发送 - 复制 — 复制选中文字到剪贴板 3. Esc / 点击别处 / 滚动页面,气泡消失

不写死任何提问模板——引用是给 AI 的上下文,问题是你的话。

实现说明

  • 纯客户端插件:主机侧无逻辑(lib/index.js 仅为可安装性存在)
  • 选中文字在 mouseup 时快照保存,点按钮不会丢选区
  • 输入框定位用结构钩子([data-composer-seat] / [data-composer-card])并回退到可见 textarea;

写入用原生 value setter + input 事件,兼容 React 受控输入框

  • 追问引用上限 2000 字;只在会话区([data-conversation-scroll])内触发,

输入框内选字不触发

FAQ

Q: 气泡不出来? A: 确认选中发生在会话区内(输入框里选字不触发);老版本 web 没有 data-conversation-scroll 时会退化为「非输入控件内即可触发」。

Q: 追问填入后没生效? A: 写入走原生 value setter + input 事件;若某版本输入框换了结构, 请在 issue 里附上 document.querySelector("[data-composer-seat], [data-composer-card]") 的结构信息。

Q: 引用的选中内容太长? A: 上限 2000 字,超长自动截断。
