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.

Features
Six independent events
Each event type has its own sound and its own volume (0–100%):
| Event | Detection | Default sound |
|---|
| Turn end / background task completed | turn/end with reason.kind === 'completed'; job → completed | Chime |
| Approval request | approval/requested frame | Ding |
| User question | question/requested frame (not plan-review shaped) | Ding |
| Plan review | question/requested frame classified as plan-review | Ding |
| Goal blocked | goal projection enters blocked | Ding |
| Background / loop failure | job → failed; turn/end error; host/agent-error | Bell |
- 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)
- Copy this package and its runtime deps (
@deepseek-ai/schemastery,
@deepseek-ai/cosmokit, @standard-schema/spec) into
$DSH_HOME/profiles/web/node_modules/.
- Append
"dsh-sound" to dsh.profile.bundles in
$DSH_HOME/profiles/web/package.json.
- 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.
