dsh-unread-dot

A DeepSeek Harness (DSH) plugin: while the app is hidden or unfocused, show an unread red dot on the macOS Dock icon and play a bubble chime when a session finishes or needs you. Clears automatically when you return.

Built entirely on the Chrome Badging API (navigator.setAppBadge / navigator.clearAppBadge) — no macOS system settings, no notification permission, no banners.

⚠️ Prerequisite: open DSH Web in Chrome and install it as an app via More → Cast, save and share → Install… so it runs in its own macOS window (PWA). setAppBadge only works inside an installed web app.

Behavior

Why the Badging API

The plugin encodes "is there new info, and what kind" with the three states the Badging API supports:

navigator.setAppBadge(3)   // red numbered badge: 3 unread results
navigator.setAppBadge()    // plain red dot: a session is running
navigator.clearAppBadge()  // clear: you're back, everything is read

• No permission, no banner, no system settings: the badge is a system-level persistent marker the page calls directly
• Dot vs number: number = unread result count, plain dot = running (the clearest distinction the API can express)
• Compatibility: DSH Web must be installed as a PWA (Chrome "Install page as app"); the API is supported from Chrome 81; from Chrome 152 the badge/notifications are attributed to the web app itself

Install

1. Add the plugin package to your DSH profile (e.g. web):

   dsh plugin --profile web add github:Bing-Bryan/dsh-unread-dot
   

2. Append it to dsh.profile.bundles in the profile's package.json:

   "dsh": {
     "profile": {
       "bundles": [ "...", "dsh-unread-dot" ]
     }
   }
   

3. Restart dsh web, then configure it in Settings → Dock 角标与通知.

Settings

How it works

1. The plugin subscribes to the DSH session list (sessions.list) and tracks read/unread state: when the window regains focus, all current attention states are marked as read
2. While minimized/unfocused, only newly occurring completion/waiting events light up the badge and chime (old events don't accumulate)
3. Running sessions only show the activity dot (plain red), never counted into the number
4. The chime plays an embedded base64 MP3 via Audio, with a cross-window lock so multiple open windows only sound once

Compatibility

• macOS Chrome (installed as PWA / "Install page as app")
• Badge: setAppBadge requires an installed web app context
• No server-side dependency — pure client plugin, HMR hot-reload with zero restarts
