How to install a DSH plugin
Installing a DeepSeek Harness plugin takes one command. This is the only install section you need — every plugin page links back here.
- Install the DeepSeek Harness CLI:
npx @deepseek-ai/dsh web - Add the plugin from GitHub:
dsh plugin add github:owner/repo - Verify the plugin loaded:
dsh plugins list
dsh plugin add github:owner/repo The command above installs the plugin into your active dsh profile. GitHub-sourced plugins may run build scripts at install time — only install plugins you trust.
How this directory is curated
This site follows the quality-over-quantity principle: every plugin is checked before it is listed.
Curated, not crawled
Each plugin is reviewed for purpose, documentation, and activity before it earns a place in the directory.
Source-linked
Every listing links directly to its GitHub repository, license, and latest commit so you can verify what you install.
Kept fresh
Plugin metadata (stars, activity, descriptions) is refreshed regularly so the directory reflects reality.
DeepSeek Harness Plugin FAQ
Quick answers to the questions people ask most about DeepSeek Harness plugins.
What is a DeepSeek Harness plugin?
A DeepSeek Harness (DSH) plugin is a package that extends DeepSeek’s open-source agent framework with a focused capability — a tool, a skill, a memory store, a UI theme, a workflow, or an integration. DeepSeek Harness is built around the principle that “everything is a plugin,” so almost every capability of the harness can be added, replaced, or removed through plugins.
How do I install a DSH plugin?
Install a DeepSeek Harness plugin with one command in the dsh terminal: dsh plugin add github:owner/repo. The CLI resolves the plugin, verifies its provenance, and installs it into your active profile. You can also install from the npm registry or from a local directory. See the installation guide for details.
Is DeepSeek Harness free to use?
Yes. DeepSeek Harness is open source under the MIT License, and the plugins in this directory are community projects, almost all of them free and open source. You self-host the harness and run it with your own model API keys.
Are DeepSeek Harness plugins safe?
Most plugins are safe, but you should verify before installing: check the source repository, the license, and recent activity, and only install plugins you trust. GitHub-sourced plugins may run build scripts at install time, so pinning a commit hash is recommended for reproducible installs. Every listing here links directly to its source so you can review it.
What is the difference between DSH and DeepSeek?
DeepSeek is the AI lab (and its models). DeepSeek Harness (dsh) is DeepSeek’s open-source agent framework — a runtime that connects models, tools, skills, sessions, and plugins. A DSH plugin is any extension built for that runtime.
Can I build my own DeepSeek Harness plugin?
Yes. The harness ships a plugin development kit and documentation for creating plugins in JavaScript/TypeScript. Start from the official template, register your plugin’s capabilities, and test it locally before publishing. You can then submit it to this directory.
