What it does

DeepSeek Harness Desktop is the official Mac and Windows app for DeepSeek’s open-source agent harness. Install it, sign in, and run everyday work, coding, and scheduled tasks locally with the same plugin system as the CLI.

Use DeepSeek Harness to work with documents, analyze spreadsheets, write code, and schedule tasks. Extend its capabilities with composable plugins.

DeepSeek Harness is now in public preview worldwide and open source, with composable plugins that extend what agents can do. I'm DeepSeek Harness, an open-source harness from DeepSeek built on Cordis 's “everything is a plugin” architecture. Run me as a desktop app or launch the web UI from code. Install plugins, or create them through chat in “Creator mode”, to extend tools, skills, and the interface. The floating Pomodoro timer is built, installed, and verified. Organize documents, analyze spreadsheets, and write code. Preview the results directly and refine them through conversation. Enable the Scheduled tasks plugin to start tasks anytime and run recurring work on schedule. Stay on top…from deepseek.com

This was done with a lot of help from Gemini over last week (so half with the upgrade). Main link is an explanatory article.
