dsh-completion-sound

A DSH (DeepSeek Harness) completion-sound bundle: plays a chime when an agent turn finishes; plays the special "Guan Yu's Song" music and shows a click-to-stop modal when a long task (≥ 10 minutes by default) finishes; optionally fires a desktop notification (browser notification first, with an automatic fallback to a system notification).

Installation

dsh plugin --profile web add github:jensentsts/dsh-completion-sound

Replace web with the profile you want to install into. Build artifacts (lib/) are committed, so installing from git needs no pnpm build authorization (pnpm ≥10 allowBuilds); it works right after dsh plugin add.

> Pin a commit so later pushes cannot silently change what runs: > dsh plugin --profile web add github:jensentsts/dsh-completion-sound#<sha>

Uninstall:

dsh plugin --profile web remove @jensentsts/dsh-completion-sound

Relationship to the built-in completion sound

The dsh-web-app bundle ships a built-in completion-sound row (ui-completion-sound → @deepseek-ai/dsh-client-ui-completion-sound). This bundle's cordis.patch.yml disables that built-in row and inserts its own row (id completion-sound), so when a web profile has both dsh-web-app and this plugin, this plugin takes over completion sounds and nothing plays twice. In a profile without dsh-web-app, the disable step is silently skipped and the insert still applies.

Features

• Completion chime: a WebAudio-synthesized two-tone chime (E5 → A5) when a turn finishes
• Long-task special music: plays special music and shows a modal when a long task finishes; click anywhere to stop
• Custom special music: point at a single audio file, or a directory (one random track is picked per play)
• Bundled audio: defaults to the bundled "Guan Yu's Song" (assets/guan-yu.wav, ~13.5 MB)
• Configurable long-task threshold: 1 minute ~ 10080 minutes (7 days)
• Desktop notification: optional, cross-platform — browser notification first, automatic fallback to a system notification (macOS osascript / Linux notify-send)
• Dedicated settings page: everything lives under "Settings → Completion sound"

Settings

Special music semantics

specialPath decides what plays when a long task completes:

• Empty string → the bundled assets/guan-yu.wav
• File path → that file (content-type derived from the extension)
• Directory path → recursively scans audio files (.aac .flac .m4a .mp3 .oga .ogg .opus .wav .webm, up to 512), picking one at random per play

> The special-music preview button sits to the left of the "music file or directory" input; it commits the path before previewing, so it always previews what is currently typed.

Architecture

This plugin is a DSH bundle: package.json's dsh.bundle.patch points at cordis.patch.yml, and it also declares dsh.client (platform web) so the module loader serves the client half to the browser.

• Host half (src/index.ts): registers the settings schema and three routes:

- /completion-sound/guan-yu.wav — bundled Guan Yu's Song (memory-cached, served as audio/wav) - /completion-sound/special — serves special music by specialPath (empty→bundled; file→served; directory→one random pick, with header x-dsh-completion-sound-random: 1) - /completion-sound/notify — POST system-notification fallback (macOS osascript / Linux notify-send) for when browser notifications are unavailable

• Client half (src/client/index.ts): binds settings, watches turn-completion events, and registers the settings.section (id completion-sound) dedicated page.

Building

Build artifacts are committed; ordinary users don't need to build. Developers rebuild after editing src/:

pnpm install
pnpm run build      # tsc -p tsconfig.json && tsdown
pnpm run typecheck  # tsc -p tsconfig.json --noEmit

Artifacts (lib/, committed):

• lib/index.js — host half
• lib/invariant.js — invariant companion
• lib/client.js — client half (browser bundle)
• lib/types/**/*.d.ts — type declarations

tsdown.config.ts is self-contained (it inlines the platform module table, the CSS Modules inline plugin, and the __ModuleLoader__ format); it depends on no monorepo preset.

Dependencies

• dependencies: runtime value dependencies (@deepseek-ai/dsh-settings, @deepseek-ai/schemastery, react, react-dom)
• peerDependencies: services provided by the host DSH profile (@deepseek-ai/cordis, dsh-api-remotes, dsh-client-*, dsh-invariants), aligned to 0.1.0-rc.6
• devDependencies: type-check and build tooling (TypeScript, tsdown, tsx, lightningcss)

System notification dependencies

The system-notification fallback requires notify-send on Linux (libnotify-bin, present on most desktop distros) and the built-in osascript on macOS. Browser notifications are used when available, so the fallback is not hit there.
