🔔 dsh-notify

Conversation-completion notifications for DeepSeek Harness — Windows toast + sound when a turn finishes, errors, a goal completes, or the agent asks/needs approval. Alerts fire only while you are away from the app; they go quiet when you are looking at it. Zero-config, with a bell in the conversation header as the control center.

Overview

When you run long tasks in DeepSeek Harness (DSH), you usually switch to other windows. dsh-notify pings you with a native Windows toast + sound when a turn completes, errors, or a goal is reached — only while the app is in the background: completion-class notifications are suppressed while the page is visible or any desktop-shell window is focused, while "the agent needs you back" alerts (ask / approval) always fire — those are exactly the moments that should interrupt you.

Features

• 🔔 Bell in the conversation header: master notifications toggle (click to mute/unmute) + volume slider (0–100%), persisted to disk in real time
• 🛌 Background-only: silent in the foreground (page visible or any shell window focused), fires in the background
• ⚠️ Ask/approval always alert: ask_user_question / approval/asked are never muted by foreground state
• 🔇 Master switch: notifications: false silences everything (including ask/approval), survives restarts
• 🌐 Bilingual: toast text follows the Windows display language (English / 中文)
• ⚙️ Zero config to start, hot-reloaded config file
• 🧵 Smart dedup: 5s per-session dedupe; turn-completion only after the agent stays idle (800ms debounce); subagent-internal sessions are skipped

Install

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

Restart dsh web.

Local development (link mode): add to the profile's package.json:

"dependencies": { "dsh-notify": "link:C:/path/to/dsh-notify" }

and make sure "dsh-notify" is in dsh.profile.bundles.

Quick start

No configuration needed — it just works after install and restart:

Want quiet? Click the 🔔 bell in the conversation header; hover for the volume slider.

Configuration

File: ~/.dsh/dsh-notify.json (defaults when absent; bell actions write back in real time).

HTTP API

All endpoints accept same-origin requests only (sec-fetch-site check).

Architecture

web page (lib/client.js)   ──visibilitychange / focus──►  POST /dsh-notify/foreground {page}
desktop shell (Electron)   ──any window focus/blur─────►  POST /dsh-notify/foreground {shell}
                                                               │ merged: foreground = page || shell
host plugin (lib/index.js) ──notify()──┐                        ▼
   session/event, goal/changed events │   done/error/goal silent in foreground, ask always
                                      └─► notify.ps1 ──► Windows toast + sound

• host (lib/index.js): event-driven; config / foreground-state API; notify() reads config → spawns notify.ps1
• client (lib/client.js): bell UI in the conversation header; page visibility / focus reporting
• notify.ps1: toast + sound executor (-SoundType done|error|ask, -Volume, -NoSound, -NoToast)
• Foreground state is in-memory only (not persisted); initial state is background so a broken reporting link can never silently swallow notifications

Compatibility

• Platform: Windows (toast via PowerShell + Windows notifications)
• DSH: web (dsh web); desktop shell optional (reports shell foreground)
• Node: >=22.13

Development

dsh-notify/
├── lib/
│   ├── index.js      # host entry (events + API; pure decision/arg logic unit-testable)
│   ├── client.js     # browser half (bell UI + foreground reporting)
│   ├── notify.ps1    # toast / sound executor
│   └── activate.ps1  # toast click handler (opens the local DSH URL only, safety-checked)
├── test/notify.test.mjs  # 22 tests (node:test, zero deps, injected spawn spy)
├── cordis.patch.yml  # bundle registration
└── package.json

Client build constraint: lib/client.js must stay in the DSH client-bundle artifact format — window.__ModuleLoader__.load({ id, factory }), no import/JSX. Keep that wrapper or the browser load will fail with "loaded without registering".

Checks:

npm run check        # node --check lib/index.js lib/client.js
npm test             # 22 tests (config / decision / event wiring / HTTP routes; no real powershell)
npm run pack:check   # npm pack --dry-run

Runtime API self-check: curl http://127.0.0.1:3080/dsh-notify/config.
