Concepts & Architecture

DeepSeek Harness turns the model adapter, tools, sessions, and the agent loop into DSH plugins, while the dsh launcher only boots a profile and combines them on demand. Grasp everything-is-a-plugin and installing, configuring, or building DSH plugins follows naturally.

DeepSeek Harness (DSH) splits AI task execution into the dsh launcher and individual DSH plugins: dsh boots configured workspaces (profiles), plugins provide capabilities, and the built-in web and headless profiles work out of the box. This category starts from the architecture — why DeepSeek Harness Plugin is designed this way and how plugins cooperate — so you install and use DSH plugins with a complete mental model.

What is DeepSeek Harness (DSH)? The "everything is a plugin" agent framework

DeepSeek HarnessDSHagent frameworkCordisplugin

DeepSeek Harness (DSH) is an open-source agent framework by DeepSeek AI with the CLI tool dsh. Its core idea is "everything is a plugin" — models, tools, interfaces and skills all connect via plugins, powered by Cordis. It is currently in developer preview.

DSH concepts & architecture FAQ

What is the relationship between DSH and DeepSeek Harness?

DSH is short for DeepSeek Harness and the name of its command-line launcher (dsh). Officially DSH is a runtime framework for AI tasks; these tutorials use DSH (DeepSeek Harness) to refer to the framework.

What does 'everything is a plugin' mean?

DSH itself only orchestrates; capabilities (workflows, tools, model access, etc.) come as plugins. DSH plugins are installed into a profile via dsh plugin and combined into your own runtime.

How do the dsh launcher and DSH plugins relate?

dsh is the DeepSeek Harness command-line launcher — it reads config, boots the profile environment, and forwards commands; DSH plugins are what it loads. Together they form the DeepSeek Harness Plugin ecosystem.

What is the difference between the web and headless profiles?

The web profile launches the graphical Web UI for interactive use; headless has no UI for scripts and automation. Both are built in, auto-initialized on first use, and can run side by side.

Should beginners learn concepts before installing?

Spend ten minutes understanding how profiles and plugins divide work before installing DSH and your first DSH plugin — troubleshooting becomes much easier afterwards. Concept articles keep tracking DeepSeek Harness evolution.
