dsh-schedule-later
A DeepSeek Harness plugin that sends a message into a chat later. Draft it in the message box, pick a time, and at that time it is posted into the same chat as a normal user message — so the model answers it exactly as if you had pressed Send. Delivery runs in the dsh host, so the browser can be closed.
The model can use it too: three tools and a skill let it schedule a check-in on its own — on a build that is still running, a page that will change, or something you said you would do later — and come back to the chat when it fires.
Install
dsh plugin --profile web add dsh-schedule-later
dsh --profile web
Restart dsh web and hard-refresh the browser. A ⏱️ Schedule button appears in the message box row, and ⏱️ Scheduled at the bottom of the sidebar.
The scheduler
- Day or night at a glance. The header is a sky that follows the chosen time, with the sun or moon on its arc; the clock face is light by day and dark with stars by night; the time carries an AM/PM pill with a sun or a moon.
- Pick a time your way. Quick picks (+5 min, +15 min, +1 hour, Tonight 9 PM, Tomorrow 9 AM), a month calendar, hour and minute columns you can click for a list or scroll to step, and a 24-hour sky slider you can drag.
- Edit the message right there. The popover’s message box is the same draft as the chat’s — typing in either shows in the other. Ctrl+Enter confirms.
Everything pending, across chats
The sidebar panel lists every pending message in every chat, soonest first, each tinted by the time it sends. Click one for its details — the full message, and Send now, Change time or Cancel, each confirmed first. Click a chat’s name to open it. A message in its last minute pulses.
Letting the model come back on its own
| Tool | What it does |
|---|---|
schedule_message |
Schedule a message into this chat, by delay_minutes or an ISO 8601 at. |
list_scheduled_messages |
List what is pending in this chat, and the current local time. |
cancel_scheduled_message |
Cancel a message the model scheduled. |
Its messages arrive marked [Scheduled by the assistant], at least 1 minute ahead and at most 30 days out, at most 10 pending per chat, and it cannot cancel yours. The bundled schedule-later skill tells it when a check-in is worth scheduling unprompted.
