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-sidebar-preview-select

> DSH Web 插件：在 dsh-better-sidebar 侧边栏预览里划选文本 → 浮动「发送到会话」→ 填入当前会话输入框（用户可编辑后再发送）。第三方增强插件，非 better-sidebar 官方组件。

特性

  • 纯 DOM 层增强：不注册任何 tab / viewer，不改动任何预览渲染——全局 mouseup 监听 + [data-dsh-better-sidebar] 区域判定 + body 外挂浮层；
  • 覆盖面板内所有可划选内容：内置 markdown/code/text 预览，以及 Office 预览插件渲染的文档文本；
  • 消息带文件上下文：从 better-sidebar 活动 tab 的路径判定类型——markdown/text 用引用模板、code 用扩展名 fence、拿不到路径时降级通用模板；
  • 填草稿不直发：走 DSH 公开 seam（ctx.sessions.scope → ctx.conversation.input.for → setDraft），输入机事务进 undo 栈，误发可 Ctrl+Z 撤销；
  • 与 dsh-sidebar-qa 共存：区域互斥（qa 限定对话区，本插件限定侧边栏面板），可同时安装。

安装

dsh plugin --profile web add dsh-sidebar-preview-select

重启 dsh web，浏览器硬刷新。前置：dsh-better-sidebar（可选 peer——未安装时本插件激活但无任何 UI/行为）。

使用

1. 在侧边栏预览（markdown/文本/代码/Office 文档）里划选一段文本； 2. 选区末尾浮出「发送到会话」按钮（含 80 字符摘要）； 3. 点击后消息填入当前会话输入框，编辑确认后发送。

开关

localStorage 键 dsh-sidebar-preview-select:enable：设为 '0' 关闭浮层（默认开启）。正式的 DSH 设置命名空间计划在后续版本提供。

边界

  • HTML 预览（sandbox iframe 内）不可达——iframe 是独立文档，document 级监听拿不到其内部选区（计划 v2 注入 inspector）；
  • code 预览（CodeMirror）划选经浏览器原生选区读取，主流环境可用；
  • markdown 选中暂不带行号（DOM 层拿不到文件全文，v1 降级为通用模板）。

开发

pnpm install
pnpm test       # vitest 纯函数单测
pnpm typecheck
pnpm build      # lib/index.js + 双 client bundle
