dsh-selection-toolbar

English | 中文

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-toolbar

or from a local checkout:

dsh plugin --profile web add /path/to/dsh-selection-toolbar

Then 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-runtime and @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.setDraft standard 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.
