Introduction

The core design philosophy of DeepSeek Harness (DSH) is “everything is a plugin.” During the development and debugging of the Web UI, developers sometimes need lighter interactive extensions. dsh-plugin-snake provides a floating button located in the overlay. After clicking it, the snake game can be run directly within the Web interface, without any additional download or compilation steps.

Plugin Overview

This is a snake game panel plugin designed for the DeepSeek Harness Web UI, maintained by user ghbhiee. It mainly addresses the need to add fun interactive elements to the Web interface by injecting a game panel into the framework’s overlay slot through a floating button.

Core Features

  • Game Panel: A snake game integrated into the DeepSeek Harness Web UI.
  • Floating Entry Point: A floating button is displayed in the framework’s overlay, and clicking it opens the game.
  • Controls: Supports arrow keys or WASD to control movement, and the spacebar to pause. Touchscreen devices support swipe gestures.
  • State Persistence: Game high scores are stored in the browser’s localStorage.
  • No Build Dependencies: Uses handwritten JavaScript and can run without configuring build tools.

Installation and Activation

The plugin needs to be added through the command-line tool, and the service must be restarted after installation.

  1. Install the plugin:
dsh plugin --profile web add github:ghbhiee/dsh-plugin-snake
  1. Restart the Web service to load the plugin:
systemctl restart dsh-web

If using macOS, you can restart it with the following command:

launchctl kickstart -k gui/$(id -u)/com.tokencv.dsh-web

Typical Usage

  • Game Control: After installation and restart, find the floating button in the DeepSeek Harness Web UI. Use the keyboard to control the snake’s movement, or use touchscreen swiping. Press the spacebar to pause the game.
  • Source Code Modification: This plugin has no build steps, and the source code is the runtime code. Directly edit lib/client.js or lib/index.js, then save and restart the service for the changes to take effect. You can use npm run check to verify syntax.

Use Cases and Cautions

  • Use Cases: Suitable for testing overlay extension capabilities in the DSH Web interface, or for light entertainment during debugging breaks.
  • Cautions:
    • The plugin is assembled at system startup and does not support hot loading; a restart is required after code changes.
    • Node.js version ^22.19.0 || >=24.0.0 is required.
    • High scores are only stored in local browser cache and are not related to server data.

Conclusion

dsh-plugin-snake demonstrates how to embed lightweight components into the DeepSeek Harness Web UI through the plugin system. For developers who need to customize UI interactions, this is a reference example implemented with native JavaScript.
