dsh-task-feedback

Running long tasks in DeepSeek Harness has one nerve-wracking moment: switching to another tab and coming back to find the Agent has been waiting for your approval for two minutes already. dsh-task-feedback is built for exactly this pain point. It maps the real-time session state onto the browser Favicon, so a quick glance at the tab bar tells you whether the task is done, in progress, or needs you.

The plugin delivers two core capabilities. First, a Favicon status indicator: once you leave the tab, the Favicon becomes a small dot that changes color based on state - green for completed, blue for in-progress or a sub-agent running, orange for pending human intervention. If the session is already idle the default whale icon is kept, following a minimum-distraction design. Three shapes are available: small dot, circle, and rounded rectangle. Second, synthesized sound alerts: twelve tones generated in real time via the Web Audio API let you assign different sounds to task completion and intervention requests, with playback scoped to always-on or only-when-the-page-is-hidden. Zero external dependencies; hover the preview button to audition.

The entire plugin is purely frontend. It uses no custom protocols, makes no LLM calls, and writes nothing to session logs - it reads state exclusively through DSH standard sessions and uiSession services. All settings (shape, sound choice, playback scope) persist in localStorage. It suits developers running long Agent tasks who frequently switch between windows, and any DeepSeek Harness user who wants to maintain task awareness at minimal visual and auditory cost.
