SpringBrand's DeepSeek Harness Explainer FAQ
Do I need an existing DeepSeek Harness installation?+
No, the setup script installs the official DSH and adds the SpringBrand OAuth MCP client automatically.
What does the DeepSeek Harness actually provide?+
It supplies a workspace, tool registry, sandbox, session log and execution loop for a model, but does not include model weights.
Can I replace the model or sandbox at runtime?+
Yes, both are plugins managed by Cordis and can be swapped via configuration patches without changing core code.
Is the project stable for production use?+
It is in developer preview; core plugins and APIs may change, so it is not recommended for production deployments requiring API stability.
How are community plugins discovered and installed?+
Plugins are published under the dsh-plugin GitHub topic and can be installed from source or via npm when packaged.
What licensing does DeepSeek Harness use?+
The official DeepSeek Harness is MIT licensed.
