deepseek-harness plugin: Everything is a Plugin in DeepSeek Harness

Official project

DeepSeek's open-source agent harness, built around an everything-is-a-plugin architecture for models, tools, sandboxes, storage, UI, and agent loops.

What this plugin does

The deepseek-harness plugin is the core of DeepSeek Harness, an open-source agent harness developed by DeepSeek AI. It adopts an architecture where everything is a plugin, powered by Cordis. Currently in developer preview, it is evolving rapidly with potential compatibility-breaking changes.

DeepSeek Harness, abbreviated as dsh, is an open-source agent harness from DeepSeek AI. Its defining feature is the deepseek-harness plugin architecture, where every component is a plugin. This design is powered by Cordis, a framework described in the paper 'A Programming Paradigm for Spatiotemporal Composability'. The project is in developer preview, meaning it is iterating quickly and may introduce breaking changes. Users can run the harness via npm or from source, with a Web UI served by default. The repository encourages community feedback through GitHub Discussions and provides documentation for development and contribution.

Documented capabilities

Plugin-based architecture

The deepseek-harness plugin architecture treats every component as a plugin, enabling modular and composable agent development. This design is powered by Cordis, which provides a programming paradigm for spatiotemporal composability.

Web UI

DeepSeek Harness includes a Web UI that is served by default when running the harness. This interface allows users to interact with the agent harness through a graphical interface, making it accessible for various tasks.

Developer preview

The project is currently in developer preview, indicating that it is under active development and may undergo significant changes. Users should expect potential compatibility-breaking updates as the harness evolves.

Practical use cases

Building custom agents

Developers can leverage the deepseek-harness plugin to create custom agents by composing plugins. The modular architecture allows for flexible and tailored agent behaviors.

Research and experimentation

Researchers can use DeepSeek Harness to experiment with agent architectures and plugin compositions, benefiting from the Cordis-based design that supports spatiotemporal composability.

Community-driven development

The project encourages community involvement through GitHub Discussions, where users can submit feedback and bug reports. This fosters collaborative improvement of the harness.

Review before you install

Read the source, recent releases, requested permissions, network access, and maintainer history before trusting a third-party plugin.
