dsh-sonic

When agents are running in DeepSeek Harness Web, the moments that demand your attention—approval prompts, ask_user_question waits, and the running-to-idle transition—can easily be buried under multiple windows or tabs. dsh-sonic adds an audio cue at each of those instants, playing a short synthesized tone the moment an event fires so you never lose track of what needs a response or has just completed.

Every sound is generated in real time by the Web Audio API on the browser side, with zero audio files and zero external dependencies. Eight presets are included: ding, dingdong, pop, chime, success, beep, alarm, and marimba. The confirmation tone and the completion tone can each be mapped to a different preset. A settings panel offers one-tap mute, a volume slider, and click-to-preview, saving all choices automatically. Two model tools are exposed as well: sonic_play triggers playback of a named preset on demand, and sonic_status reads the current panel selections.

Built for developers and power users who rely on DeepSeek Harness Web for day-to-day agent work. The plugin mounts as a bundle alongside the Web profile and survives process restarts with no separate server required. If you enjoy tinkering, you can add new note sequences to the PRESETS array and register them in the host-side enum to grow a custom sound palette of your own.
