DeepSeek released DeepSeek Harness (dsh) into worldwide public preview as an open-source agent harness built on a Cordis “everything is a plugin” architecture. The runtime supports desktop and web deployment, composable plugins for tools/skills/UI, Creator mode for generating plugins via natural-language prompts, scheduled tasks, and local file/code execution. Official pages and source repository make the system immediately available for developers to extend agent capabilities without proprietary lock-in.
