dsh-notify

Windows desktop notifications for DeepSeek-Harness (DSH).

Hand a task to DSH, switch to something else, and get pulled back only when it matters: a toast tells you the task is done, or that the agent is waiting on you. Click the toast to return to the app.

Windows only. On other platforms the plugin loads and stays idle.

What it does

Moment	Toast
A task finishes	DSH · 任务完成 with the assistant's last answer
A task ends in an error or an unexpected stop	DSH · 任务已结束
The agent asks you a question and nobody answers within 6 s	DSH · 需要你确认 with the question

Clicking the toast, or its 打开 DeepSeek-Harness button, brings DSH to the front. If the window is minimized it is restored; if it was closed to the tray it is reopened. This uses the dsh://notify URL handler that the desktop app already registers.

Toasts stay quiet while you are already looking at the app: the page reports from the browser whether one of its tabs is the foreground tab of a visible window, and no toast is raised in that case. Plan reviews keep their own approval UI and are not announced by default.

Install

Published on npm — this is what the in-app Plugin Center uses:

dsh plugin --profile web add @cmwl1231/dsh-notify

For the Desktop app, replace the profile:

dsh plugin --profile desktop add @cmwl1231/dsh-notify

Install straight from this repository instead (no npm package involved):

dsh plugin --profile web add github:lixiangdong122333/dsh-notify

Quit DSH before running the command, and start it again afterwards. A newly added bundle is read at startup, not picked up live.

Configure

Open Settings → Plugins → this plugin. The form edits the dsh-notify row of your profile's cordis.patch.yml and applies each change immediately, with a Send a test notification button to confirm the whole chain works.

Editing that row by hand works just as well — both write the same block. Every key is optional; the defaults below are what an install without overrides uses.

- id: dsh-notify
  config:
    onTurnEnd: true              # toast when a turn ends
    notifyEndKinds:              # which endings are worth a toast
      - completed
      - error
      - max-tokens
    minTurnMs: 0                 # ignore turns shorter than this (ms)
    notifyQuestions: true        # toast for an unanswered question
    questionDelayMs: 6000        # how long a question waits before the toast
    notifyPlanReviews: false     # announce plan reviews too
    skipWhenFocused: true        # stay quiet while a DSH tab is in the foreground
    skipWhenOthersRunning: true  # stay quiet while another session still works
    bodySource: answer           # answer | prompt | none
    bodyLength: 150              # characters of body text
    sound: default               # default | silent | important
    titleCompleted: "DSH · 任务完成"
    titleEnded: "DSH · 任务已结束"
    titleQuestion: "DSH · 需要你确认"

forked and interrupted are handovers inside the app rather than a finished task, so they are not offered as endpoints. sound: important keeps only the question toast audible.

How it works

The plugin is a Cordis plugin: it exports apply(ctx) and registers listeners on the host context.

• Turns — DSH commits a turn/end event to each session's log. The plugin follows that feed and raises a toast when a turn ends, skipping subagent sessions and turns you cancelled yourself.
• Questions — a user-questions/request reaches the plugin before the web answerer sees it. The plugin holds the request, and once questionDelayMs passes without an answer it raises the toast and steps aside, so the normal answerer takes over as usual. The plugin never answers, and never interferes with the on-screen question card.
• Focus — a small script served by the host reports tab visibility and focus back to the host, which is the only reliable signal for "the user can already see this".
• Delivery — notify.ps1 raises the toast through WinRT as the app's Start Menu shortcut. Windows resolves a toast's application name from the AppUserModelId registry entry, not from the toast XML, so the script (re)writes that entry before each send. Without it the header falls back to showing the raw shortcut path.

Requirements

• Windows 10 or 11
• Windows PowerShell 5.1 (present on every supported Windows)
• DeepSeek-Harness with a Start Menu shortcut for the app

Development

# plugin logic and the settings store, against a fake context — no DSH needed
node test-plugin.mjs

# toast payload and encoding checks (Windows, sends one real toast)
powershell -ExecutionPolicy Bypass -File test-toast.ps1

notify.ps1 must keep its UTF-8 BOM. Windows PowerShell 5.1 reads a .ps1 file in the system code page unless a BOM says otherwise, and the action label is Chinese — without the BOM it renders as mojibake. The test suite checks this.
