dsh-notify-win

DeepSeek Harness (DSH) Windows notification plugin — native toast + taskbar flash when a task finishes or your input is needed.

Question — single select

Toast timeout → taskbar flash

Screenshots are from Windows 11. The taskbar flash is animated; the screenshot shows the DSH taskbar button highlighted by the system warm pulse.

✨ Features

• 🔔 Native Windows toast (bottom-right, Win10/11 system style)
• 💡 Taskbar flash (FlashWindowEx) when DSH is in the background
• 🖱️ Click-to-focus — clicking a toast opens DSH and switches to the corresponding session
• ✅ Triggers when a task finishes (root agent goes idle)
• 🗜️ Triggers when context compaction finishes (session/event → compaction/end)
• ❓ Triggers when your input is needed (approval / ask_user_question)
• 📋 Single-select question toast: native dropdown with up to 5 options + “自定义答案” (custom answer) text input + Cancel / Send
• ⏰ Timeout flash fallback: if an interactive toast is ignored and dismissed by the system timeout, the taskbar flashes so the pending question is not missed
• 🖼️ Hero banner with the DeepSeek Harness logo (light/dark theme aware)
• 🚀 Fire-and-forget: no service, no model approval, no settings namespace

🚀 One-line install

dsh plugin --profile web add dsh-notify-win

Requires pnpm on PATH (corepack enable if missing). See Install for details.

Install

1. Prerequisite: pnpm

   corepack enable
   

   Or without admin, put a user-level shim in a PATH directory:

   Set-Content -Path "$env:LOCALAPPDATA\Microsoft\WindowsApps\pnpm.cmd" -Value "@echo off`r`ncorepack pnpm %*`r`n"
   corepack pnpm --version
   

2. Install the plugin

   # From npm (recommended)
   dsh plugin --profile web add dsh-notify-win
   
   # Or directly from GitHub:
   dsh plugin --profile web add github:Andyqwe44/dsh-notify-win
   
   # If github: is blocked, use SSH:
   dsh plugin --profile web add git+ssh://git@github.com/Andyqwe44/dsh-notify-win.git
   

3. Verify

   dsh --profile web --dump-config   # look for: # == dsh-notify-win / - id: dsh-notify-win
   

4. Restart and test

   dsh web
   

   Complete any task. The first notification self-registers the branded toast identity (Start Menu shortcut + AppUserModelID, one-time). If the toast header still shows DeepSeekHarness without an icon, restart Explorer once:

   Stop-Process -Name explorer -Force; Start-Process explorer
   

Requirements

• Windows 10/11
• DeepSeek Harness, any profile (web recommended)
• PowerShell 7 or Windows PowerShell 5.1 (5.1 is used automatically as fallback)
• .NET 10 Desktop Runtime (x64) — only needed for interactive question toasts (ask_user_question); done/compact toasts use PowerShell and do not require it

Configuration

Edit $env:USERPROFILE\.dsh\profiles\web\cordis.patch.yml:

- id: dsh-notify-win
  config:
    doneTitle: 'DeepSeek Harness · Task complete'
    doneBody: 'Your task has finished.'
    compactTitle: 'DeepSeek Harness · Context compacted'
    compactBody: 'Context compaction finished, you can continue.'
    questionTitle: 'DeepSeek Harness · Action needed'
    questionBody: 'An approval or decision is waiting.'
    askTitle: 'DeepSeek Harness · Question for you'
    askBody: 'The assistant asked you something.'
    dedupMs: 1500              # suppress duplicate notifications within this window
    showProject: true          # prefix body with project label

To disable:

- id: dsh-notify-win
  disabled: true

Restart after install/disable changes (web profile HMR is disabled by default).

How it works

Concern	Implementation
Trigger "done"	agent/status event with status: 'idle' (root agents only)
Trigger "compact"	session/event → compaction/end (no error)
Trigger "question"	approval/request waterfall + tools/execute for ask_user_question
Done/compact toast	WinRT Windows.UI.Notifications via notify.ps1 with hero banner, falls back to NotifyIcon balloon
Interactive question toast	.NET helper dsh-toast-question.exe (reads dropdown/text input and posts the answer back to the host)
Taskbar flash	EnumWindows + FlashWindowEx (FLASHW_TRAY | FLASHW_TIMERNOFG = 14)
Execution	Fire-and-forget subprocess (powershell / dsh-toast-question.exe)

The plugin registers no service, tool, or settings namespace — a plain consumer row, safe in any profile.

Known limitations

• Native toast text is compact: only about 4 lines are displayed, so long content is truncated.
• The native selection dropdown may collapse when the pointer moves onto the popup; if the toast is then dismissed by timeout, the taskbar flash still reminds you.
• FlashWindowEx uses the system's warm-pulse highlight; custom colors are not possible.
• Windows never flashes the foreground window — the taskbar button only flashes when DSH is in the background.
• Cancelling a running turn also goes idle, so a cancelled task still triggers the "done" toast.
• Notifications are deduplicated per session within dedupMs (default 1500 ms).
• Interactive question toasts require the .NET 10 Desktop Runtime on the machine.

Development

npm run check     # syntax check
npm test          # logic smoke test (mocked ctx)

# Show a real toast + taskbar flash:
powershell -NoProfile -File lib/notify.ps1 -Kind done -Title "test" -Body "test"

# Rebuild the interactive question helper:
dotnet publish src/DshToastQuestion/DshToastQuestion.csproj -c Release -r win-x64 --self-contained false -p:PublishSingleFile=true -o lib

Roadmap

• V1 (implemented): done + compact + question toasts; single-select dropdown with custom answer; Cancel / Send; timeout → taskbar flash fallback.
• V1.1 (experimental / not stable yet): multi-select question toast by numbered input.
• V2 (planned): fully self-contained packaging (no .NET runtime install) and/or background activation so toast buttons submit without any foreground activation.
