dsh-selection-toolbar 
English | [中文](README.zh.md)
Select text inside a DeepSeek Harness conversation and a small floating toolbar appears above the selection: 复制 · 引用 · 询问 · 解释 · 翻译 · 总结 (copy · quote-reply · ask · explain · translate · summarize).
All AI actions reuse the current session — the selected text is sent into the active conversation as a normal user message, so the model has full context.
Features
| Action | Behavior |
|---|---|
| 复制 Copy | Copy the selected text to the clipboard. |
| 引用 Quote | Insert the selection as a markdown blockquote (> …) at the composer caret. |
| 询问 Ask | Opens an inline input; Enter sends 你的问题 + selection. Leaving the input empty sends the raw selection as a plain message. |
| 解释 Explain | Send 请解释下面这段内容： + selection. |
| 翻译 Translate | Send 请把下面这段内容翻译成中文： + selection. |
| 总结 Summarize | Send 请用简洁的语言总结下面这段内容： + selection. |
The popup hides on Escape, scroll, or clicking elsewhere; the 询问 input stays open while typing (focusing the input collapses the page selection without closing the popup).
Settings
The plugin appears in 设置 → 插件 → 插件列表 as a native-style card — the same collapsible look as the built-in 终端 / 网页搜索 entries — with:
- 弹窗出现延时 — delay before the toolbar appears after selecting (0–500 ms)
- 功能开关 — toggle each toolbar entry individually (复制 · 引用 · 询问 ·
解释 · 翻译 · 总结); disabled entries disappear from the popup immediately, and 全部开启 re-enables everything at once
- 恢复默认 — reset all options
Options persist in the browser (localStorage) and apply to the popup live, no reload needed.
Install
From GitHub:
dsh plugin --profile web add github:suiyideali/dsh-selection-toolbaror from a local checkout:
dsh plugin --profile web add /path/to/dsh-selection-toolbarThen restart the web app so the new client bundle is picked up.
Requirements
- dsh web (v0.1.0-rc.6 tested)
- The profile must already mount
@deepseek-ai/dsh-client-runtimeand
@deepseek-ai/dsh-client-ui-slots (standard in the web profile).
Architecture notes
- Client-only: the plugin has no host half. AI actions prompt the session
through the client sessions service — binding(id).session.prompt(...) — the exact path the composer itself uses, so queueing and error surfaces are native.
- Quote insert uses the official
inputActions.setDraftstandard prop from
the conversation.input.dock slot. It deliberately avoids sessions.scope() + event bails, which the dynamic-plugin facade forbids (cross-context guard); the markdown blockquote is the same shape as other quote-reply plugins.
- Selections are scoped to the message list (
[data-chat-flow]) and
exclude the composer, inputs, and contenteditable regions.
- Fixed actions build fixed prefixes; the 询问 question caps at 2k chars and the
selection at 20k chars to keep injected messages bounded.
