DeepSeek Harness (DSH) is an open-source agent harness for working with AI models. It helps you connect a model provider, use local files, manage sessions, set approval boundaries, and extend the setup with plugins, MCP, skills, subagents, and workflows. The site focuses on getting you started fast, fixing specific errors, and exploring extensions. It also includes guides for Windows, macOS, and Linux, plus a web UI workflow for running tasks in a local workspace. A community desktop wrapper is available for people who prefer a desktop app over terminal setup.
