DSH Notification Center Plugin

Developed by 610la, the DeepSeek Harness (DSH) Notification Center plugin addresses the issue of background tasks being unable to receive status updates. It supports browser system notifications and 21 configurable sound effects, and adapts to native desktop notifications. Users can independently configure events such as conversation completion, errors, and waiting for approval, with custom sounds and volume supported. The plugin is released under the MIT open-source license; after installation, users must grant notification permissions and click the page to trigger the sound effects. When packaged as a desktop app, it automatically switches to native notifications.
