DeepSeek Harness Sound Notification Plugin (dsh-plugin-sound-notify)

The `dsh-plugin-sound-notify` plugin, officially provided by DeepSeek Harness, is designed to provide auditory feedback for changes in agent task status. It can play notification sounds when a task is completed or waiting for user input (such as approval or selection), and supports volume adjustment, sound preview, and dark mode adaptation. Users need to install it via PowerShell and restart the service, then allow playback in the settings for it to take effect. The plugin contains only basic settings, has no privacy concerns, is licensed under the MIT License, and can effectively improve awareness of agent workflows.
