dsh-later: Adding Scheduled Sending to DSH

DeepSeek Harness (DSH) adopts a plugin-based architecture and supports extending functionality through plugins. During development or use, you often need to set timed reminders or continue sending messages after the current conversation ends. The dsh-later plugin solves this problem: it enables scheduled sending, timed reminders, and delayed sending in DSH.

Core Role¶

This plugin adds scheduling capabilities to DSH: users can enter a message, set a time, and after the time elapses, it will automatically be sent as the user, or displayed in the conversation as a reminder message. Even if the web page is closed, the server will trigger it on time.

Installation and Activation¶

Install it using the official command:

dsh plugin --profile web add dsh-later

After installation, restart the Web service to take effect.

Key Features¶

/later delayed sending: Type a line in the input box, and at the specified time it will send that content as you.
/schedule timed reminder: After setting a time, a reminder line is displayed in the conversation at the scheduled time.
Scheduling panel: There is a “Scheduled Send” button on the right side of the input box, supporting quick chips (e.g., 10 minutes later, 1 hour later), custom times, send preview, task list, and cancel all.
Sidebar status indicator: Conversations with active reminders display a pixel clock in the sidebar. Purple indicates scheduled, amber indicates triggered within 5 minutes, and red indicates due.
Triggers even when the web page is closed: Reminders are stored on the server, so they arrive on time even if you switch devices or close the web page.
Multilingual: Follows the DSH interface language.

Typical Usage¶

Command format:

/schedule 明天9点 提交周报
/later 1532 提醒团队同步进度
/later +1h*3 起来喝水
/later +2h+1h+30m 催我交周报

Notes¶

The default limit for reminder content is 1000 characters.
When using the multiple-entry syntax, up to 10 entries are allowed, and intervals must be at least 60 seconds.
Reminders do not apply across conversations; child conversations derived from the current conversation do not inherit the parent conversation’s reminders.
At the scheduled time, it is displayed as a “Timed Reminder” message, rather than pretending to be sent by you.

Summary¶

dsh-later provides a simple and easy-to-use scheduled task capability, suitable for scenarios requiring background execution or long-standby reminders.
