dsh-desktop-tools

English | 中文

dsh-desktop-tools is one DSH Desktop plugin for the selection toolbar, floating assistant, screenshots, long screenshots, and screen recording.

Install

Use DSH Desktop >=0.2.2-rc.1 <0.3.0-0, then add this repository as one plugin:

https://github.com/1997liuyh-boop/dsh-desktop-tools.git

Install tag 0.4.10. The plugin includes its own helper, preload, native feature modules, static assets, and settings page. No separate dsh-desktop-runtime, dsh-selection-toolbar, dsh-floating-ball, or dsh-capture package is required.

Installation does not require an Electron path.txt file and does not use the koffi install script. The helper loads the matching prebuilt Koffi platform package.

Prerequisite: a standalone Electron

The plugin runs its features in a separate Electron helper process and never downloads Electron itself. Which executable it starts depends on how DSH Desktop was installed:

• Installed DSH Desktop (the installer build, with resources/app.asar next to the executable, e.g. DeepSeek Harness.exe): that executable always starts DSH itself, so a standalone Electron is required. The helper uses the first one found:

  1. the plugin's electronExecutable setting;
  2. the DSH_DESKTOP_TOOLS_ELECTRON environment variable;
  3. $DSH_HOME/electron/ (~/.dsh/electron/ by default): electron.exe on Windows, Electron.app/Contents/MacOS/Electron on macOS, electron on Linux. Extracting an official Electron release archive into this folder produces exactly this layout.

  If none exists, enabling a feature fails with an error listing the paths it tried, and the settings page shows it.

• DSH Desktop started from a bare Electron (development): the helper reuses that Electron and nothing else is needed.

Use the same Electron major version as your DSH Desktop; other versions are untested.

Prerequisite: dsh-vision-router

Extract text, Translate, and Knowledge graph on screenshots and long screenshots, and Recording to knowledge graph, recognize text with the OCR tools of dsh-vision-router (>=3.2.0). Install and enable it and keep its "tool" switch on. All other tools (annotations, pin, save, forward, recording, long-screenshot stitching) work without it.

The DSH plugin manager cannot install one plugin together with another, so use any of these:

• In Settings → Desktop tools → Screenshot, click Install dsh-vision-router on the prerequisite card (Enable when it is installed but disabled), then restart DSH when asked;
• When you use one of those three tools before it is installed, the result window shows the same install button;
• Or run dsh plugin add dsh-vision-router in a terminal.

package.json declares it as an optional peerDependencies entry so marketplace checks warn about an out-of-range version. The default OCR engine is auto: local Tesseract first, falling back to the vision model configured in vision-router (which receives the image). For strictly local OCR, set the vision-router default OCR engine to Tesseract only.

Screenshot, long screenshot, and recording

Press the shortcut (system-wide, also while DSH is in the background) to open a toolbar at the top of the screen with three modes: Screenshot, Record screen, and Long screenshot.

Screenshot, after you select an area:

• Shape (rectangle / ellipse / line; hold Shift for a square, circle, or 45° steps), pen, arrow, text (text / auto-incrementing numbers), mosaic (brush with adjustable strength), plus color, stroke width, and font size;
• Pin to desktop (always-on-top window: drag to move, scroll to zoom, double-click or Esc to close, right-click to copy, save, or reset the size);
• Long screenshot (starts scrolling capture with the current area);
• Knowledge graph, Translate, and Extract text (need dsh-vision-router): shown in a separate result window. Translate and Knowledge graph create DSH sessions in the "Screenshots and recordings" workspace; the knowledge graph is a Mermaid diagram plus node and relation lists, saved as Markdown or exported as PNG;
• Undo (Ctrl/Cmd + Z), Forward (to a new DSH conversation with an optional message, or the system share panel), Save to disk (Ctrl/Cmd + S), Cancel (Esc), Done (copy to clipboard, Enter).

Recording:

• Scope: a selected area, an application window, or a full screen;
• Format MP4 / GIF / WebM (WebM is used when Chromium cannot encode MP4); quality SD 720p / HD 1080p / Original;
• System sound and microphone (mixed into one track when both are on); GIF has no sound;
• Recording to knowledge graph: key frames with clear visual changes (up to 12) are kept during recording and their text is turned into a knowledge graph afterwards. Speech is not transcribed;
• While recording, a control bar offers pause / resume (Space), stop and save (Enter), and discard (Esc). MP4 / WebM stop at 15 minutes or 500 MB, GIF at 3 minutes.

Long screenshot: select the scrolling area, click Start, and scroll down inside the frame with the mouse wheel. Frames are matched row by row and stitched, excluding fixed headers and footers; Auto scroll is also available. Afterwards you can copy, save, pin, extract text, translate, build a knowledge graph, or forward the result. The maximum height is 30000 pixels.

Platform limits:

Feature	Windows	macOS	Linux
System sound	Supported	macOS 13+; falls back to video only	Not supported
Long screenshot auto scroll	Supported	Needs Accessibility permission	Not supported (scroll manually)

Replace earlier plugins

If the profile already has any of the four earlier entries, remove dsh-selection-toolbar, dsh-floating-ball, dsh-capture, and dsh-desktop-runtime before installing dsh-desktop-tools@0.4.10, then restart the Host. The new plugin stores settings in desktop-tools.json; it does not import the retired packages' separate settings files. Its defaults enable the selection toolbar and floating assistant, and disable screenshots and recording.

Settings

The DSH settings panel adds one Desktop tools entry with four submenus:

• Selection toolbar: enablement, target language, model, and compatibility copy.
• Floating assistant: enablement, avatar, conversation/background models, permission preset, coordinate mode, and system permissions.
• Screenshot: enablement, the screenshot shortcut (default Ctrl/Cmd + Shift + S), an optional long-screenshot shortcut, and dsh-vision-router status with one-click install.
• Screen recording: enablement, the recording shortcut (default Ctrl/Cmd + Shift + R), and default format, quality, system sound, microphone, and knowledge graph.

Shortcuts are global; a combination already taken by another program is not registered, so choose another one. Selection and floating assistant are enabled by default. Screenshot and recording are disabled by default. Configuration is stored in the profile's desktop-tools.json; each save reports both persistence and actual helper application status.

Build

Use Node 24.9 or newer:

npm install --ignore-scripts
npm test
npm run build

The build creates the Host, helper, preload, Remote descriptor, Client settings bundle, and TwCSS-based assets. macOS native modules are compiled when the build runs on macOS; Windows and Linux keep the Darwin-only modules unavailable.
