DeepSeek Harness Desktop: application for Windows and Mac, installation and plugins

DeepSeek has released its agent harness as a standalone application for Windows and macOS: it’s now an installer rather than a terminal launch. According to the documentation and release log, Node.js and the command line are no longer needed. There are installers for both systems. The author breaks down installation and plugins: what’s inside and how to connect extensions. All of this is based on the official documentation and release log. If you want to try DeepSeek’s agent scenarios on your computer, the barrier to entry has become lower: just download the installer and add the plugins you need.
