dsh-attention-reminder

Sound and on-screen alerts for DeepSeek Harness: when the agent needs your approval (an approval/request) or an answer (ask_user_question), the plugin strikes a short chime, raises the DSH window, and floats a card above the page.

Two independent toggles — sound and popup — both remembered across reloads and restarts.

Install

dsh plugin --profile <profile> add github:chenyuiyu/dsh-attention-reminder

On DSH Desktop, install it from Settings → Plugins. The plugin is plain JavaScript: no build step, no dependencies.

The two toggles

Both live behind the 🔔 button at the right end of the session header.

• Sound — one bell strike (WebAudio, ~0.5 s). Each new request chimes exactly once and never repeats; the card stays on screen until you answer it.
• Popup — window.focus() to put DSH in front, a floating card above the page naming what is waiting (up to 3 cards, the rest folded into “+N more”), and a system notification where the browser allows one.

The panel also has Send a test reminder, which travels the same path as a real alert.

Toggles are stored in $DSH_HOME/plugin-data/dsh-attention-reminder/state.json (default ~/.dsh/plugin-data/...).

How it works

• Host half (index.js) listens to the waterfall events approval/request and user-questions/request and keeps the unanswered ones in a bounded queue (24 entries). An entry leaves the queue when the promise returned by next() settles or the request's AbortSignal aborts. It only observes: every handler delegates with return next(), so approvals and questions behave exactly as before. The queue and the toggles are served as GET/POST /api/attention-reminder through connection.fetch.register.
• Web half (client.js) polls that route once a second and announces only ids it has not seen yet. Cards register into shell.overlay; the 🔔 panel into conversation.session.header.utilities.

Plugins have no host-to-page push channel, which is why the page polls; @deepseek-ai/dsh-deja uses the same HTTP route pattern.

Notes

• Audio starts after one interaction with the page — a browser rule, not this plugin. If DSH was just opened and an alert fires before you touched anything, one click on the page fixes it and the next alert is audible.
• window.focus() cannot always beat the Windows foreground lock; the floating card and the system notification still appear.
• The system notification needs the browser's notification permission, requested the first time you enable popup or press the test button (both are user gestures).
