dsh-power-button

Restarting DeepSeek Harness used to mean killing a process by hand, waiting for the port to free up, and relaunching it with the exact same arguments. dsh-power-button collapses that entire procedure into a single sidebar power button: click it, pick Restart or Shutdown, and a Windows-style full-screen transition carries you through the handoff. No terminal, no memorized commands.

Under the hood the plugin ships a self-contained restart engine with zero third-party dependencies and no PowerShell or taskkill calls. It writes a detached CommonJS helper that runs outside the process tree, waits for the old process to exit and the port to release, then polls every session log until two consecutive samples report identical size and mtime, guaranteeing no in-flight write-behind buffer can interleave stale sequence numbers before the fresh instance starts. Alongside the GUI, the plugin registers /restart and /shutdown commands plus a restart_harness model tool so an AI conversation can also trigger a safe, delayed restart.

It is built for DSH users who want routine lifecycle changes to be one click away yet care that session integrity is preserved. Shutdown defaults its focus to Cancel and requires an explicit second confirmation before anything terminates; restart success is verified by a per-process instance ID that must change, so a brief outage never fakes a successful cycle. The interface is fully localized in Chinese and English, following the profile locale preference out of the box.
