dsh-task-notify

English | 中文

A DSH (DeepSeek Harness) browser plugin that tells you when your agent finishes work — a completion chime, and a tab-title alert while you are on another tab.

---

Install (30 seconds)

Prereqs: the dsh CLI (DeepSeek Harness).

dsh plugin --profile web add @yangzhe1991/dsh-task-notify

Then restart the Web GUI and refresh the browser tab. That's it — the package ships prebuilt artifacts, so nothing compiles on your machine and no allowlist is needed. dsh plugin auto-appends the bundle to your profile's dsh.profile.bundles.

Other install methods (usually not needed):

Method	Command	Builds on install	Notes
npm registry (recommended)	dsh plugin --profile web add @yangzhe1991/dsh-task-notify	No	Prebuilt, quickest
tarball	dsh plugin --profile web add ./dsh-task-notify-0.1.0.tgz	No	Offline-friendly
git	dsh plugin --profile web add github:yangzhe1991/dsh-task-notify	Yes (via prepare)	Requires one-time allowBuilds in pnpm-workspace.yaml

What it does

• 🎵 Completion chime — a synthesized two-tone chime (no audio files) when:
  • an agent turn finishes in your current session (normal reply, error, or abort) — this covers ordinary conversations;
  • a background job settles in any session (completed / failed / killed — background bash/pwsh, subagents, workflows, …).
  • Success: ascending do → mi. Failure / kill: descending mi → do.
• 🔔 Tab-title alert — while the page is not the active tab (document.hidden), a finished task changes the title to 🔔 N 个任务完成 — <original title>; switching back to the tab restores it.
• ✅ No false positives — switching sessions, loading history, or refreshing the page never re-alerts for old turns. Only work that actually finishes while you are watching the current session triggers.

First-run note: click the page once

Browsers block audio until the user has interacted with the page (autoplay policy). Click or press a key anywhere in the page once — chimes are unlocked from then on. The tab-title alert is never affected.

FAQ

Q: I finished a task but heard nothing. A: You likely haven't interacted with the page yet (see above), or the task was a plain foreground tool call — those don't trigger; only agent turns and background jobs do.

Q: It beeped when I switched to another session. A: That was a bug in early versions, fixed since — old turns in the newly opened session were mistaken for fresh completions. Update the plugin (dsh plugin --profile web update @yangzhe1991/dsh-task-notify) and refresh the page; only turns that finish while you're in the session will alert now.

Q: Which tasks exactly trigger the chime? A: (1) The agent completing a turn in your current session — every round of work, whether it answered, errored, or was aborted; (2) any background job settling in any session.

Q: Can I change the sound or turn things off? A: See Customization below.

Q: What does the plugin actually install? A: A profile bundle: a config layer (cordis.patch.yml) plus a browser-half bundle (lib/client.js) that the DSH web app discovers automatically — no manual configuration, no UI added.
