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:

cd dsh-selection-toolbar && pnpm install   # or: npm install
dsh plugin --profile web add /path/to/dsh-selection-toolbar

The host half depends on @deepseek-ai/dsh-settings and @deepseek-ai/schemastery (declared in package.json), so install the checkout's dependencies before adding it from a local path; installing from GitHub resolves them automatically.

Then restart the web app so the new client bundle is picked up.

Requirements

• dsh web (v0.1.0-rc.6 and v0.1.0-rc.8 tested)
• The profile must already mount @deepseek-ai/dsh-client-runtime (standard in the web profile). Since rc.8 the settings card registers through the namespace-keyed settings.plugin.item slot, and the small host half serves the dsh-selection-toolbar settings namespace so 设置 → 插件 dispatches the card; on rc.6 the same registration satisfies the older list-slot contract.

Architecture notes

• Client-only behavior, tiny 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. The only host code registers the settings namespace (see Requirements) so the settings card is served on rc.8+; the card's option values stay in browser localStorage (client-only design).
• 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.
