dsh-macos-notify
Native macOS notifications for DeepSeek Harness, with event-specific sounds, notification filtering, multi-task coalescing, and a first-level settings page in the DSH Web UI.
Features
- Notification Center alerts when a turn completes, fails, is blocked, or waits for approval.
- Separate sounds for completed, error, aborted, and approval events; any event can be muted.
- System sound picker, in-page sound preview via afplay, and managed custom sound import and deletion from the Web settings page.
- Custom imports are converted to AIFF, limited to 5 MB and 10 seconds, capped at 20 managed files / 50 MB total, and stored in
~/Library/Sounds.
- A 1.5-second coalescing window and optional digest mode prevent parallel tasks from flooding Notification Center.
- Recent notification diagnostics explain whether an event was sent, queued, suppressed, or failed; they persist across restarts.
- A six-event test matrix validates completed, error, approval, aborted, coalesced, and digest notifications.
- Daily quiet hours and temporary pauses with custom durations and a remaining-time display.
- Common toggles and the sound picker save instantly from the read-only view; number inputs are clamped to safe ranges.
- Duplicate error suppression with a configurable cooldown window and volatile-fragment normalization.
- Project path rules for muting, error-only alerts, or important-project bypasses.
- Minimum turn-duration filtering avoids notifications for near-instant replies.
- Optional Web-tab focus suppression and macOS HID idle-time gating.
- Dedicated wording for API rate limits, including provider retry timing when available.
- OSC 9 notifications for supported terminals, including tmux DCS passthrough.
- Live settings updates without restarting DSH.
Requirements
- macOS
- Node.js 22 or newer
- DeepSeek Harness with the
web profile
Install
Install the published npm package:
npx -y @deepseek-ai/dsh plugin --profile web add dsh-macos-notify
npx -y @deepseek-ai/dsh web
Alternatively, install the latest source directly from GitHub:
npx -y @deepseek-ai/dsh plugin --profile web add github:CrombastiC/dsh-macos-notify
Then open Settings → macOS notifications from the first-level settings navigation.
To remove the plugin:
npx -y @deepseek-ai/dsh plugin --profile web remove dsh-macos-notify
Local development install
From this repository checkout:
npx -y @deepseek-ai/dsh plugin --profile web add .
npx -y @deepseek-ai/dsh web
dsh plugin anchors relative paths to the invoking directory and forwards the install to pnpm in the selected profile. Avoid absolute-path bundle overlays in cordis.dev.yml; install the local package through plugin add instead.
Configuration
The settings namespace is macos-notify. Values changed from the Web card apply live.
| Option | Default | Description |
|---|
onCompleted | true | Notify when a turn completes normally. |
onError | true | Notify for errors and blocked turns. These alerts bypass completion gates and digesting. |
onAborted | false | Notify when a user aborts a turn. |
onApproval | true | Notify immediately when a tool waits for approval. |
minDurationSec | 30 | Suppress completed-turn notifications shorter than this many seconds; 0 disables the threshold. |
onlyWhenIdleSec | 0 | Require this many seconds of keyboard/mouse idle time for completed notifications; 0 disables idle gating. |
onlyWhenUnfocused | true | Suppress completed notifications while any DSH Web tab is focused. |
digestMinutes | 0 | Collect completed notifications into a periodic digest; 0 sends them immediately. |
includeSubagents | false | Include subagent sessions instead of notifying only for top-level sessions. |
channel | auto | auto, osascript, or osc9. |
sounds.completed | Glass | Sound for completed turns. |
sounds.error | Basso | Sound for errors, blocked turns, and rate limits. |
sounds.aborted | empty | Sound for aborted turns; empty means silent. |
sounds.approval | Ping | Sound for approval requests. |
coalesceMs | 1500 | Window for merging simultaneous turn results; disables merging. |
Project rule modes
mute — suppress every notification under the configured project path.errors — allow only errors, blocked events, and approval requests.important — bypass minimum-duration, focus, idle, quiet-hour, and temporary-pause filters.
The settings page keeps the last 50 decisions, the duplicate-error cooldown state, and recent session titles, persisted to ~/Library/Application Support/dsh-macos-notify/state.json so they survive DSH restarts. Each row records whether an event was sent, queued, suppressed, or failed and includes the reason. This history does not contain message content.
Notification channels
auto uses OSC 9 when the terminal is recognized as supporting it, and falls back to osascript otherwise.
Recognized OSC 9 terminals include iTerm2, WezTerm, Kitty, Ghostty, and Warp. tmux sessions are wrapped in DCS passthrough automatically.
Sound selection applies to the osascript channel. With OSC 9, the terminal controls whether and how a notification sound is played.
Custom sounds
In the settings page, select Edit → Import sound. Supported inputs include AAC, AIFF, CAF, FLAC, M4A, MP3, OGG, Opus, and WAV.
The host validates the extension, decoded size, converted duration, managed-file count, and total managed size before writing anything to the user sound directory. Imports are converted to 44.1 kHz mono AIFF using macOS afconvert, with ffmpeg as a fallback for formats that afconvert cannot decode. Existing files are never overwritten; a numeric suffix is added instead.
New imports are recorded in ~/Library/Application Support/dsh-macos-notify/sounds.json and can be deleted from the settings page. If a sound is currently selected, deletion asks for confirmation and changes affected events to silent. Files remain in ~/Library/Sounds if the plugin is removed without deleting them first.
Known limitations
- The plugin is macOS-only. Native notifications use
osascript, and custom import uses macOS audio tooling.
- OSC 9 sound behavior belongs to the terminal and ignores the per-event sound selection.
- The Web settings page uses the trusted
/macos-notify RPC channel because the current DSH Web settings proxy has a namespace allowlist for built-in settings.
- Only sounds imported by v0.2.0 or later are tracked as managed sounds. Earlier manually copied/imported files can still be selected, but must be removed from
~/Library/Sounds manually.
Development
The package is intentionally build-free:
index.js — host plugin, event handling, notification delivery, settings RPC, and sound import.client.js — hand-written DSH client module for focus reporting and the first-level Web settings page.src/policy.js — pure policy helpers (quiet hours, project rules, duplicate merging) covered by unit tests.src/state.js — validated, atomic persistence for diagnostics, duplicate state, and session titles.cordis.patch.yml — profile bundle patch.
Run the release checks:
node --check index.js
node --check client.js
npm test
npm pack --dry-run
