Quote for DeepSeek Harness

Select text in the conversation and put it into the composer as a markdown block quote — like Codex does, and without touching the draft you already typed.

A small, quiet Quote button appears next to the selection. Click it, or press Ctrl+Shift+. (Cmd+Shift+. on macOS), and the selection lands in the composer as:

> first line of the quoted text
> second line of the quoted text

One blank line separates the quote from whatever you had already written. The quote is appended to your draft, never substituted for it.

✨ Features

• Quote the selection. Assistant and user messages alike — anything selectable in the transcript.
• Never loses your draft. Insertion goes through the composer's own captureInsertion() / insertText(), which inserts one undoable edit at the caret. If that path is unavailable the draft is read back from the composer and the quote is appended to it — the plugin never overwrites what you typed.
• Keyboard first. Ctrl+Shift+. on Windows and Linux, Cmd+Shift+. on macOS, and the chord can be re-recorded in the settings.
• Disappears when it should. Collapsed selection, a click in empty space, Esc, a scroll, a resize, a tab switch or a session change all remove the button.
• No false positives. Selections inside input, textarea or contenteditable surfaces — including the composer itself — are ignored.
• Tidy text. The selection is trimmed, CRLF is normalized, runs of blank lines collapse into a single quoting line, and the quote is capped at a configurable length.
• Theme-native. Every colour is a DSH token (--dsw-alias-*) with a fallback, so the button and the settings card look right in the dark and the light theme. It honours prefers-reduced-motion, carries an aria-label and shows a focus ring.
• English and Russian. The UI follows document.documentElement.lang (ru* → Russian, otherwise English).
• No dependencies, no build step. One host file, one browser file.

📦 Installation

Pick whichever route matches how you use DSH.

From the Desktop app

1. Open Plugins.
2. Choose Add plugin and enter dsh-quote — or the absolute path to this folder when you are installing a local checkout.
3. Enable the bundle if it arrives disabled. The settings card appears on the plugin's own page.

From the CLI

dsh plugin --profile web add dsh-quote

To install a local checkout instead of the published package, pass its absolute path:

dsh plugin --profile web add /absolute/path/to/dsh-quote

From source

Nothing needs to be built or installed:

git clone https://github.com/naletko/dsh-quote.git
cd dsh-quote
node test/metadata-check.mjs
node test/quote-logic-check.mjs

🚀 Usage

1. Select some text in the conversation — part of a message, a whole paragraph, several paragraphs.
2. Click Quote beside the selection, or press the hotkey.
3. The block quote is added to the composer, after a blank line, leaving the rest of your draft alone.

Typical use: select the paragraph of an answer you disagree with, quote it, and type your follow-up underneath.

⌨️ Keyboard shortcut

The setting is stored as the portable chord Mod+Shift+., where Mod resolves to Ctrl on Windows and Linux and to Cmd on macOS. Any chord with at least one modifier can be recorded in the settings card; the plugin matches letter keys by physical key code, so the shortcut keeps working on a non-Latin keyboard layout.

⚙️ Settings

The card lives on the plugin's page in Plugins and behind the row's Configure control.

The card shows a live preview of exactly what will be inserted.

Settings are read and written through the plugin's own route, GET/POST /api/dsh-quote/config, and stored as dsh-quote-config.json in the DSH home directory — $DSH_HOME when that variable is set, otherwise ~/.dsh. The browser keeps a copy in localStorage purely so the composer knows your settings on the first paint.

🔒 Privacy

• No network access. The plugin's host half serves one local route and nothing else; it never calls out to any service.
• No secrets, no telemetry, no analytics. There is nothing to configure but four display preferences.
• Local files only. The only file written is dsh-quote-config.json under $DSH_HOME.
• Local requests only. /api/dsh-quote/config refuses any request that does not clearly originate from loopback, and rejects bodies above 16 KiB.
• Nothing leaves the page. The selected text is formatted in the browser and inserted into the composer; it is never uploaded, logged or persisted by this plugin.

🔄 Updating

The plugin updates itself: Settings → Plugins → Quote carries an Updates section that asks GitHub for the branch revision, shows the version installed next to the version on main, lists what changed, and hands the pinned commit to the harness plugin manager in one click. Reload the page afterwards; if the version has not changed, restart the application — the host half only loads at boot.

A deployment without a plugin manager prints the manual spec instead, for Plugins → Add plugin: github:naletko/dsh-quote.

🧩 Requirements and compatibility

• DeepSeek Harness core 0.2.0-rc.2 (the web client of the Desktop app or a browser session).
• Uses the conversation.input.right slot (a list seat — the single conversation.input.activity seat is deliberately left free, because occupying it evicts the voice plugin's microphone), plus plugins.bundle.config and plugins.row.config, and the composer's captureInsertion() / insertText() / setDraft() actions.
• Windows, macOS and Linux. Paths are built with node:path, the hotkey understands metaKey, and no platform-only API is used.
• No npm dependencies, no bundler, no build step.

🧪 Tests

node --check index.js client.js
node test/metadata-check.mjs      # exports map, icon, locales, slot registrations
node test/quote-logic-check.mjs   # quoting rules, hotkeys, settings, placement

client.js is not a module — it registers itself with DSH's browser module loader — so both tests load it through a fake window.__ModuleLoader__, exactly as the browser does, and drive the plugin's own functions through the __test hook it exposes. The host half is a real ES module and is imported directly.
