DeepSeek Open-Sources DeepSeek Harness v0.1 for Agent Development
DeepSeek Harness on GitHub is now available in Developer Preview under the MIT license. The agent harness is built around the Cordis meta-framework and follows a “everything is a plugin” architecture: models, tools, skills, sessions, sandboxes, filesystems, loops, orchestration, and UI are all implemented as replaceable and extensible plugins. This allows developers to mix, match, replace, and extend components when building their own agent harnesses.
