DeepSeek launched DeepSeek Harness, an open-source agent framework now in global preview with packaged desktop builds for macOS and Windows (Linux via the deepseek-ai/dsh npm package). Built on the Cordis "everything is a plugin" architecture, it handles documents, coding, sourced research and background tasks, and can generate new plugins conversationally — the official demo had it write, install and verify a floating pomodoro plugin in 5m24s. A notable expansion from model vendor to agent platform.
