dsh-attention

Desktop attention alerts for DeepSeek Harness Web.

The bundle tells you when a session finishes a turn (always — even the one you are reading) and when an agent is waiting for approval, a question, or a plan review (while the page is in the background). It is a GitHub-distributed DSH bundle, not a shell modification.

What it does

Each channel is independent and can be toggled in Settings → Alerts:

Single-producer rule: while a browser tab is alive (heartbeat fresher than ~8 s), the page owns the banner and the chime; the host backs off. If every tab is closed or frozen, the host fires the banner itself (with the bundled chime) — no duplicates, no gaps. Completions and waterfall approvals collapse onto a host-minted per-session ordinal. Questions and plan reviews occupy a live slot: the first tab to report open mints the identity, later tabs collapse, and close (when the wait leaves the session list) releases the slot so the next real question can ring. Concurrent reports of one identity single-flight: the host grants sound and fallback to exactly one caller. A client-side native failure is soft-recorded so echoes collapse; a backup failure leaves the event unclaimed so the first recovering tab can fall back. Completion edges observed while preferences are still loading are stashed and flushed once loaded.

When the native notifier binary is missing (notify-send absent, and so on), the host reports it, the Alerts page shows native notifications as unavailable, and the browser Notification fallback takes over automatically.

Install

dsh plugin --profile web add github:shaomingbo/dsh-attention#v0.1.0

Or run the package installer:

npx --yes github:shaomingbo/dsh-attention#v0.1.0

Restart dsh web, then hard-refresh the browser. To update:

dsh plugin --profile web update dsh-attention

To remove it:

dsh plugin --profile web remove dsh-attention

For a local checkout:

npx --yes /path/to/dsh-attention --source link:/path/to/dsh-attention

Settings

Open Settings → Alerts to toggle:

• Master enable
• Tab title / favicon
• Sound
• Native desktop notification
• Browser notification fallback
• Event classes: approvals, questions/plan reviews, finished tasks

Preferences live in $DSH_HOME/attention.json (default ~/.dsh/attention.json) so they survive a browser refresh.

Behaviour notes

• Finished turns alert unconditionally — watching the page included. Approvals and questions stay quiet while you are looking at the page.
• Native notifications are loopback-only. A remote Web GUI cannot trigger them.
• The host listens to approval/request but always calls next(). It never answers an approval.
• The first visit may show a toast asking for browser notification permission. That permission is only used as a fallback when native notifications are unavailable.

Development

npm test
npm run check

lib/ is the release authority. The browser half is a hand-written window.__ModuleLoader__ bundle, matching other optional DSH Web plugins.
