Introduction

When doing image understanding or providing supplementary explanations in DSH, the common path is to first open the system screenshot tool, select the content, and then switch back to the DSH input box to paste manually. dsh-screenshot integrates this process into the DSH composer: a camera button is provided next to the input box, a global shortcut is provided, and the listener’s start/stop is bound to the DSH Desktop lifecycle. Below is an introduction to its capabilities, installation method, and notes.

What is it

dsh-screenshot is a DSH client plugin maintained by Alain-Prot0s5 and licensed under the MIT license. It targets Windows 10 (1809+) and Windows 11 and primarily solves the problem of “quickly entering the DSH input box after taking a screenshot”: after the system screenshot is completed, the plugin automatically pastes the image into the composer, reducing manual copying and window switching.

This plugin is specific to DSH Desktop. Host lifecycle, DSH Desktop process watchdog, and foreground detection all rely on DSH Desktop; therefore, the Web side can only be used in a restricted scenario.

Core Features

The following lists verified capabilities.

  1. Camera Button: Located in the composer tool row; clicking it triggers the system screenshot, and it can automatically paste after the selection is completed.
  2. Global Shortcut: Default Alt+A; modifiers and keys are configurable.
  3. Listener Lifecycle: The listener starts with DSH Desktop and stops when DSH Desktop closes.
  4. Settings Page: Configurable global shortcut, auto-paste toggle, background paste toggle; changes take effect immediately.
  5. Reliability Handling: Non-blocking clipboard wait, single-shot debounce, cancel detection, legacy SnippingTool cleanup, watchdog fallback.

Installation and Enablement

First, confirm the environment: the system is Windows 10 (1809+) or Windows 11, and the desktop profile of DSH Desktop is used. This plugin relies on the system Snipping Tool (ms-screenclip:) and Win32 APIs, and PowerShell 5.1 is expected to be present.

Install from GitHub:

dsh plugin --profile desktop add github:alain-prot0s5/dsh-screenshot

Install from npm:

dsh plugin add @alain-prot0s5/dsh-screenshot

In the compatibility notes for DSH Desktop >= 2.0.2, the full scoped package name @alain-prot0s5/dsh-screenshot is required.

After the steps above, restart DSH Desktop. After starting, you can see the camera button next to the input box, or you can press the global shortcut directly to start taking a screenshot.

Typical Usage

  1. Open the session in DSH Desktop that requires inputting a screenshot.
  2. Click the camera button next to the composer, or press the default shortcut Alt+A.
  3. Use the system screenshot tool to select the area.
  4. After the screenshot is completed, the plugin executes auto-paste according to settings; if auto-paste is disabled, the image will remain in the clipboard.
  5. If DSH Desktop is in the background and the background paste toggle is enabled in the settings page, the plugin will switch to the foreground and paste.

If the Web side needs to use the trigger service, the standalone listener dsh-screenshot-script/ can be used. Due to restrictions on foreground detection, automatic paste detection on the Web side is limited, and screenshots usually remain in the clipboard.

You can also combine it with dsh-vision-router as needed to form a screenshot -> question -> image understanding workflow.

Suitable Scenarios and Notes

Suitable for Windows users who frequently handle screenshots in DSH Desktop and need to quickly get images into the input box. Especially for scenarios like screenshot explanation, image understanding, and visual debugging.

Notes before use:

  • Only supports Windows 10 (1809+) and Windows 11; does not support macOS, Linux, Windows 7/8.
  • The plugin is specific to DSH Desktop; Web side capabilities are limited, it is recommended to use the desktop version as the primary method.
  • The project notes that it is AI-generated, beginner-level code, and has not undergone professional security auditing. Since the plugin runs in the DSH host/client environment and executes with the current dsh process permissions, you should review the source code, check dependencies, and verify the license before using it in a production environment.
  • The license is MIT.

Conclusion

The value of dsh-screenshot lies in merging the copy, switch, and paste steps between Windows screenshots and the DSH input box into a single trigger, making it suitable for daily use in DSH Desktop to supplement context with screenshots.

The plugin can be found in the community directory by searching for the plugin name dsh-screenshot; that directory is an independent site and is not equivalent to the official app store of DeepSeek or Huafans. See the GitHub repository:
