virggle/dsh-shutdown-after-task

Shut down Windows automatically after DeepSeek Harness tasks complete. Zero-dependency plugin for the DeepSeek Harness web profile.

Run long tasks (batch migrations, model generation, overnight jobs)? Click the "任务完成后关机 / Shutdown after task" button in the bottom-right corner and the computer shuts down once the tasks finish — with a cancellable countdown.

中文

Features

• Floating text button (bottom-right): toggles the "shutdown after task completes" mode. Off by default — never arms itself.
• Cancellable countdown: when the task completes, a 60 s banner shows the remaining seconds with a Cancel shutdown button (POST /cancel → shutdown /a) — no reliance on the OS notification that cannot be cancelled.
• New-task interrupt: starting a new task during the countdown aborts the shutdown automatically while keeping the mode armed.
• Cancel exits the mode: clicking "Cancel shutdown" aborts this shutdown AND disarms the mode, so the next task will not trigger another one.
• Success-only: a batch with agent/error is skipped (banner notice), mode stays armed.
• Multi-session aware: "task complete" = all root sessions idle (subagents fold into their root).

Install

dsh plugin --profile web add github:<owner>/dsh-shutdown-after-task

Restart DSH, then refresh the page (Ctrl+R) if the button does not appear.

Usage

1. Click "任务完成后关机" — the button turns yellow (armed).
2. Run your tasks.
3. All root sessions idle with no errors → countdown banner appears.
4. Click "取消关机 / Cancel shutdown" to abort this shutdown and exit the mode; or let the countdown run out — the computer shuts down.

Config

Edit the profile's cordis.patch.yml:

- id: dsh-shutdown-after-task
  config:
    countdownSec: 60      # countdown seconds (10–600, default 60)
    marginSec: 5          # extra seconds on the OS `shutdown /t` (0–60, default 5)
    onlyOnSuccess: true   # shutdown only on a clean batch (false = shut down either way)

Behavior

Item	Detail
Trigger	after arming, all root sessions go idle
Success check	no agent/error in the batch (when onlyOnSuccess: true)
Countdown	countdownSec s, live banner, cancel button
OS command	shutdown /s /t <countdownSec + marginSec> at countdown start
Cancel	GUI button (exits mode) / new task during countdown (keeps mode)
State	GET http://127.0.0.1:<port>/api/dsh-shutdown-after-task/state

Log

$DSH_HOME/dsh-shutdown-after-task.log — mount, arm, trigger, and cancel events.

How it works

• Plain config-layer cordis plugin: webServer.tapIndex injects the UI script into every index response; host HTTP routes back the state and actions. No client bundle, no build step.
• Listens to agent/status / agent/error (see @deepseek-ai/dsh-agent runtime-types).
• Routes and injection are disposed on unload.

Limitations

• Windows only (shutdown.exe); inert with a log line on other platforms.
• Mode state is in-memory: DSH restart resets it to off.
• A root session that is idle but has queued inbox work still counts as idle.
• The button appears after a page refresh (script injected per index response).

Uninstall
