dsh-ai-question-chime

dsh-ai-question-chime

Plays a small chime when the AI asks the user a clarifying question, so you don't miss it and can answer promptly. Built for DeepSeek Harness (DSH).

• 🔔 Two detection paths — either a ? / ？ character in the assistant's message, or an ask_user_question tool call (the standard DSH tool for clarification).
• 🎵 Web Audio API synthesis — no audio files, works on every OS (Windows / macOS / Linux).
• ⚙️ Settings page — Settings ⚙️ → AI Question Chime. Toggle on/off, adjust volume, test the sound. Persists in localStorage.
• 🪶 Zero system dependencies — no shell, no native notifications, no special permissions.
• 🚀 Works in every preset — once installed, it runs in any session (no need to switch presets).
• 🌐 Localized — English / 简体中文 / Tiếng Việt. Settings and documentation all match the UI locale.

Architectural pattern inspired by kaixinbaba/dsh-complete-notify. Thanks for sharing the standard DSH plugin layout.

Installation

Option 1 — From npm (recommended)

# Global install (or let dsh plugin manage it for you)
npm install -g dsh-ai-question-chime
# Register into the web profile
dsh plugin --profile web add dsh-ai-question-chime
# Restart dsh web to apply
# macOS launchd:
launchctl kickstart -k gui/$(id -u)/com.dsh.dsh-web
# Otherwise just stop and start dsh web manually

Option 2 — From GitHub (no npm account needed)

dsh plugin --profile web add "github:lediemquynh/dsh-ai-question-chime"
# Restart dsh web

Option 3 — Local link (for development)

dsh plugin --profile web add link:/path/to/dsh-ai-question-chime
# Edit code → restart dsh web → changes take effect (no reinstall needed)

Usage

1. Open any session in dsh web (any preset).
2. When the AI asks you a clarifying question (a ? in the message, or an ask_user_question tool call) → you'll hear a 2-note ascending chime (988 Hz → 1319 Hz, ≈0.2 s total).
3. Settings ⚙️ → AI Question Chime (or its localized label) lets you:
   • Enable / disable the chime
   • Adjust the volume (slider, 0–100 %)
   • Click Test chime to preview the sound
4. In Settings → Plugins → Plugin list (插件列表), you'll see a card for dsh-ai-question-chime showing Mounted / 已挂载.

Notes

• Browsers block autoplay on the first load. Sending your first message in dsh naturally unlocks AudioContext (any click or keypress also works).
• The plugin only runs while the dsh tab is open — this is a general limitation of Web Audio, not a bug. If you close the tab, the chime won't play.
• If you use multiple browser tabs of dsh, each tab runs its own copy of the chime — they don't share state.

Uninstall

dsh plugin --profile web remove dsh-ai-question-chime
# Restart dsh web

How it works (technical)

DSH plugin model

• A DSH client plugin is a JavaScript module that registers itself with window.__ModuleLoader__.load({ id, factory }). The factory receives a require function and returns a module.exports object.
• The module.exports shape is { name, inject, apply(ctx) }. inject declares which Host services the plugin needs (slots, locale, conversationEvents); the Cordis loader injects them before calling apply.
• apply(ctx) runs once at plugin boot. Inside, you can:
  • Register UI strings via ctx.locale.register(NS, { zh, en, vi }).
  • Subscribe to conversation events via ctx.get('conversationEvents').register({ kind, target, match, start, update, buildViewNode }).
  • Inject settings pages via ctx.slots.inject('settings.section', …).
  • Set up persistent effects (e.g. audio unlock listeners) via ctx.effect(fn, label).

Chime trigger logic

• match(event) runs for every client-side conversation event. When event.type === 'assistant/message', it returns a match id (one per event.seq) so the loader calls update.
• update(context, match) receives the event payload. It reads event.data.message, runs isAssistantQuestion(msg), and if true, calls playChime(cfg.volume).
• isAssistantQuestion(msg) returns true if:
  1. The message contains a ask_user_question tool call (deep walk through content blocks), OR
  2. The message text contains ? or ？ AND the message role is assistant.

Sound synthesis

• playChime(volume) creates an AudioContext (lazily, on first call), then schedules two sine-wave oscillators:
  • 988 Hz, starts at t=0, duration 0.09 s.
  • 1319 Hz, starts at t=0.10, duration 0.09 s.
• Each oscillator goes through a GainNode with exponential attack (12 ms) and decay to silence. Master volume is cfg.volume (0–1).
• AudioContext is unlocked lazily on the first pointerdown / keydown to comply with Chromium's autoplay policy.
• A 1200 ms cooldown (BEEP_COOLDOWN_MS) prevents repeated chimes when the AI sends multiple chunks in quick succession.

Development

npm run check         # node --check for both lib/index.js and client/client.js
npm run test:loader   # evaluate client.js in a sandboxed __ModuleLoader__ stub

The sandbox script (scripts/simulate-loader.mjs) verifies:

• __ModuleLoader__.load is called exactly once with the right id.
• The factory returns an exports object with name, inject (including slots), and apply.
• apply(ctx) runs without throwing on a stub context.
• ctx.locale.register, ctx.get('conversationEvents').register, and ctx.slots.inject are all invoked.

If you change the plugin, run both commands before committing. CI on awesome-dsh-plugin runs the same checks.

Tuning the sound

All audio parameters live in client/client.js at the top of the playChime function. Common tweaks:

What you want	Change
Higher / lower pitch	const tones = [[988, 0], [1319, 0.10]]; — try [[659, 0], [880, 0.10]] (lower) or [[1319, 0], [1760, 0.10]] (higher)
Longer chime	const dur = 0.09; → 0.15
Three notes instead of two	Add a third tone: tones.push([2093, 0.20])
Louder default	const DEFAULT_CFG = { enabled: true, volume: 0.4 };
No cooldown (chime on every event)	const BEEP_COOLDOWN_MS = 0;
Square / triangle / sawtooth wave	osc.type = 'sine'; → 'square', 'triangle', or 'sawtooth'

After editing, restart dsh web. There's no need to reinstall.

Browser compatibility

• Chrome / Edge / Brave / Opera (Chromium 90+): full support.
• Firefox 88+: full support.
• Safari 14+: full support (note: webkitAudioContext fallback included for older Safari).

The plugin does not use any experimental Web APIs.

Known limitations

• Browser tabs that are not focused may throttle AudioContext. If you switch away from dsh before the AI asks, you might miss the chime.
• The plugin does not work in browsers where the page is muted (system-level audio off).
• The plugin only sees client-side assistant/message events. If the Host side filters or rewrites messages before sending, the detection might miss some questions.

Publishing updates

1. Bump the version in package.json (follow semver).
2. Update the changelog / README if relevant.
3. Commit and push to GitHub: git push origin main.
4. Publish to npm: npm publish.
5. Users who already installed via dshmarket will see an "Update available" badge in the Updates tab and can update with one click.
