dsh-sound

English | 中文

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

📬 Submitted to Awesome DSH Plugin — PR #752 (pending maintainer approval)

Features

Six independent events

Each event type has its own sound and its own volume (0–100%):

• Completion respects the “quiet current session” option; attention events (approval /
  question / plan-review / goal-blocked / failure) always ring.
• User abort, killed jobs, and max-tokens / blocked / interrupted turns stay silent.
• Events come from events.mux plus events.host. Mux-open replay of still-pending
  approval/question frames (refresh recovery) does not ring; each rpcId rings at most once.
• When the event stream is unavailable or frames fail to unwrap, the plugin falls back to
  snapshot diffing.
• Multiple tabs: the same event rings only once (BroadcastChannel tie-break). A single
  tab plays immediately, with no 40 ms handshake.

Sound sources

Each event picks one sound from a Radio.Button group in the settings panel:

• Built-in synthesized sounds — Ding / Chime / Bell / Complete / Success, generated live
  with Web Audio, no audio files required.
• Mute — silence that event.
• Local file — choose any MP3/WAV/etc. file; a file picker appears below the event row
  once selected. Uploaded files are stored in IndexedDB (dsh-sound-audio), immune to the
  localStorage quota.

Settings panel (Settings → 声音通知 / Sound Notification)

Master switch, six event rows (volume slider on the title row; Radio.Group of Radio.Button
options below — click to select and play; a local-file row with a choose/replace
button appears when 本地文件 is selected), and config export/import.

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-sound

# Restart the server (or refresh the page), then open Settings → 声音通知

Other profiles work the same way: dsh plugin --profile <name> add dsh-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-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-sound:config), sanitizing every read and filling defaults. Uploaded
  local music files are stored in IndexedDB (dsh-sound-audio) instead —
  no localStorage quota limits.
• Config keys: enabled, quietCurrent, and six sound + six volume fields —
  completionSound / approvalSound / questionSound / planReviewSound /
  goalBlockedSound / failureSound (builtin key, none, local, data: URL,
  or audio:<id>) and completionVolume … failureVolume (0–1).
  localFiles keeps the last chosen local file per event so switching to a
  built-in sound and back does not drop it.
• 0.2.0 migration: older configs are upgraded automatically — defaultSound
  becomes completionSound, voice/TTS values degrade to the per-event default,
  and workspaces / debounceMs / global volume / voice settings are dropped.
• Export / import: the settings panel downloads the full config as JSON
  (IndexedDB audio references are inlined as data URLs) and restores it from a
  JSON file — moving browsers or machines does not require reconfiguration.
• The host half also registers the dsh-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      # 100+ assertions across host and client halves (Node only, no browser needed)
npm run check # syntax check

Layout:

Profile development note: the profile's pnpm uses nodeLinker: hoisted,
which COPIES file: dependencies into node_modules at install time —
edits to this checkout do not reach the running app until you either
re-run pnpm --dir ~/.dsh/profiles/web update dsh-sound or replace the
copied directory with a symlink to this checkout. The web server reads
bundle content per request (only the boot-page rev hash is cached at
startup), so after refreshing the copy a browser hard-refresh (Cmd+Shift+R)
is enough — no server restart needed.

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