dsh-plugin-notify-sound

English | 中文

A DeepSeek Harness (DSH) plugin for the Web UI: play a customizable ringtone when a task
finishes — per workspace — and an attention sound whenever something needs a human.

Features

Completion sounds (per workspace)

• Plays when a session turn finishes (running: true → false) or a background job completes.
• The sound is resolved per workspace: a workspace-specific override wins, otherwise the default.
• Three sound sources:
  • Built-in synthesized sounds — 6 options (Ding / Chime / Bell / Complete / Success / Mute),
    generated live with Web Audio, no audio files required.
  • Voice announcement (TTS) — the browser speaks a custom phrase (e.g. “我做完啦！”, “All done!”)
    using a system Chinese voice; voice and rate are configurable.
  • Custom audio — upload any MP3/WAV/etc. file.

Attention sounds (when a human is needed)

The following events always ring (they are not affected by the “quiet current session” option):

Event	Detection	Default sound
Approval request	session pendingInteraction: approval	generic attention sound
User question	pendingInteraction: question	generic attention sound
Plan review	pendingInteraction: plan-review	generic attention sound
Goal blocked	goal projection enters blocked	generic attention sound
Background task failure	job status failed	Bell (dedicated failure sound)

Each kind can override the generic attention sound, or use a shared TTS phrase
(e.g. “需要你的确认” / “Your confirmation is needed”).

Settings panel (Settings → 通知铃声 / Notification Sounds)

Master switch, “quiet when viewing the current session”, default completion sound,
per-workspace completion sounds, generic + per-kind attention sounds, voice settings
(voice / rate / preview / refresh), per-row preview and custom-audio upload.

Install

Requires a DSH version with bundle-plugin support (dsh.profile.bundles + dsh.bundle.patch)
and pnpm on PATH (corepack enable or npm i -g pnpm).

# One command: pnpm installs the package and adds it to the profile's bundle layer
dsh plugin --profile web add dsh-plugin-notify-sound

# Restart the server (or refresh the page), then open Settings → 通知铃声

Other profiles work the same way: dsh plugin --profile <name> add dsh-plugin-notify-sound.

Manual install (without pnpm)

1. Copy this package and its runtime deps (@deepseek-ai/schemastery,
   @deepseek-ai/cosmokit, @standard-schema/spec) into
   $DSH_HOME/profiles/web/node_modules/.
2. Append "dsh-plugin-notify-sound" to dsh.profile.bundles in
   $DSH_HOME/profiles/web/package.json.
3. Restart dsh web.

Configuration storage

• The browser half persists its configuration in localStorage (key
  dsh-notify-sound:config), sanitizing every read and filling defaults.
• The host half also registers the dsh-plugin-notify-sound settings namespace: on rc.6 the
  settings API allowlist (WEB_SETTINGS_NAMESPACES in dsh-host-apiproxy) does not expose
  third-party namespaces to browsers, so the client does not depend on settingsScope today;
  the registration keeps the migration path open for future releases.

Development

npm test      # 50+ assertions across host and client halves (Node only, no browser needed)
npm run check # syntax check

Layout:

• lib/index.js — host half: registers the settings namespace (schema + defaults)
• lib/client.js — browser bundle: completion/attention event detection, sound engine
  (Web Audio / TTS / Audio), settings panel
• lib/types/index.d.ts — host-side type declarations
• cordis.patch.yml — bundle patch layer (inserts the notify-sound row)
• tools/ — tests and verification scripts (not shipped in the npm package)

Publish

npm login                       # npm account (2FA recommended)
npm publish --access public
