cc-dsh-notifier DeepSeek Plugin

Windows desktop notifications for Claude Code and DeepSeek Harness sessions Permission requests · Questions · Waiting for input · Click-to-return

English · <a href="README-zh.md">中文</a>

cc-dsh-notifier raises a native Windows toast with sound when an agent needs your attention and you are not looking at its window. It serves Claude Code through its hook system and DeepSeek Harness through a small bundle plugin, sharing one daemon pipeline. Clicking a toast returns you to the session window. Zero third-party npm dependencies.

Features

Feature	Description
Interruption events	Notifies on permission requests, questions, and waiting for input
Focus awareness	Suppresses notifications while the session window is focused; notifies only when it is not
Click-to-return	`SetForegroundWindow` targets the session window; browser tabs activate via CDP, with a UIA fallback
Multi-session	Each session binds its own window handle; toasts carry the session identity
Localized notifications	Toast text follows the Windows display language (`auto`) or a `language` setting (`zh`/`en`)
DeepSeek Harness	The `dsh-notifier` plugin covers web and tui profiles with one install

Quick Start

Prerequisites

Windows 10 or 11
Node.js 18 or later
Python 3 with the winrt packages: pip install winrt-runtime winrt-Windows.UI.Notifications winrt-Windows.Data.Xml.Dom

Install (Claude Code)

node scripts/install.mjs

The installer backs up ~/.claude/settings.json, injects five hooks, registers the cc-notifier AppUserModelID, and writes the default config. Open a new Claude Code session afterwards.

Install (DeepSeek Harness)

Recommended — download the tarball from the latest release and install it (no repository clone, no credentials):

dsh plugin --profile web add ./baobaolaodie-cc-dsh-notifier-0.1.5.tgz
dsh plugin --profile dsh-tui add ./baobaolaodie-cc-dsh-notifier-0.1.5.tgz

> 版本说明 / Version note: 顶部徽章 0.1.2 是 root 包版本;上方 tarball 名 0.1.5 是 dsh 插件包版本,两者是两个独立的发布单元(en: top badge = root package, tarball = dsh plugin; independent release units). Alternative — git install (clones the whole repository, zero config):

dsh plugin --profile web add github:baobaolaodie/cc-dsh-notifier
dsh plugin --profile dsh-tui add github:baobaolaodie/cc-dsh-notifier

> GitHub Packages (@baobaolaodie/cc-dsh-notifier) exists as a maintainer convenience channel only: GitHub Packages' npm registry always requires a read:packages token for downloads, even for public packages (verified). Use the tarball or git install instead.

Verified against dsh 0.1.0-rc.6 on Windows 11 (2026-08-16): web and tui profiles, permission/question/waiting-for-input notifications, focus-aware silence, click-to-return, and the tarball install flow.

Usage

Claude Code

Start a session and switch away. The system notifies when Claude requests a permission, asks a question, or finishes a turn.

claude
# switch to another window; toasts appear when Claude needs you

DeepSeek Harness

The plugin forwards dsh session events into the same pipeline. Web sessions bind to the browser window; tui sessions bind to the terminal window:

dsh web          # or: dsh --profile web
dsh-tui          # or: dsh --profile dsh-tui

Manual trigger (testing)

node scripts/test.mjs permission-request   # permission-request | ask-user-question | stop | session-start

Toasts are suppressed while the target window is focused, so switch away to observe them.

Configuration

Edit ~/.cc-notifier/config.json (created on install):

Key	Default	Description
`enabled`	`true`	Set to `false` to disable notifications globally
`dedupWindowMs`	`0`	Deduplication window (ms); `0` = no dedup; `>0` merges per session+type
`pythonPath`	empty	Absolute path of the toast interpreter (written by the installer); empty = `python` from PATH
`pollIntervalMs`	`10000`	Daemon window-poll period (ms)
`windowWhitelist`	`[]`	Browser process whitelist for dsh web binding/focus (e.g. `chrome.exe`/`msedge.exe`)
`sound`	`true`	Set to `false` to mute toast sound
`language`	`auto`	Toast language: `auto` (system display language, `zh-`→zh, `en-`→en, other/failure→en), `zh`, or `en`

Architecture

An event-driven pipeline runs only while sessions are active. Claude Code hooks and the dsh plugin both produce the same normalized payloads; a resident daemon decides whether to notify, and a Python agent shows the toast:

%%{init: {'theme': 'base', 'themeVariables': {'fontSize': '14px'}}}%%

The daemon is single-instance: it wakes on demand, exits after 60 seconds of no sessions, and self-restarts when its code changes. Sessions re-register automatically after a daemon restart.

Deployment

CI runs on GitHub Actions (test × 6 matrix across Node 18/20/22 on Ubuntu and Windows, plus quality, pr-policy, docs-links, and a summary job). See .github/workflows/ci.yml.
