Manages model integration and agent execution as a composable plugin layer.
DeepSeek Harness is an open-source agent runtime built on the Cordis plugin kernel. It lets developers compose agent capabilities — models, tools, skills, sandboxes, and sessions — through configuration rather than code changes, making it easier to deploy and maintain AI agents in production environments.
