Give DeepSeek Harness an "App Store": One Command, Browse 595 Plugins

Have you ever had a moment like this: you want to give your AI assistant one more capability, like changing a skin, adding memory, or connecting a database, but after scouring GitHub you can't find a decent entry point, and end up having to dig through the source code yourself?

I had the same frustration recently while playing with DeepSeek Harness (dsh for short). Until I discovered that this framework, which claims "everything is a plugin," has actually quietly grown a complete plugin ecosystem: there's a visual plugin marketplace, and even an AI shopping guide that helps you find plugins. Install them, and you're just one command away from "letting an agent do the work for you."

Today's article will thoroughly explain these two powerful tools: dsh-market plugin marketplace and dsh-find-plugin plugin search. There's also a free dsh introductory e-book I've compiled at the end.

For those who prefer learning by video, don't worry. I've published a free DeepSeek Harness tutorial on Bilibili, demonstrating step-by-step from environment setup to practical application. Following along visually is more intuitive than reading text: https://www.bilibili.com/video/BV1qrgc68Ehn/

First, Get to Know: dsh's Plugin Mechanism

dsh's core design philosophy is everything is a plugin: models, tools, sandboxes, session storage, and even the agent loop itself can be extended through plugins. But with more plugins comes a problem: where to find them? How to install them?

The official graphical interface itself doesn't have an entry point for "browsing plugins," so the community stepped in and created two things:

• dsh-market: A visual plugin marketplace, essentially dsh's app store
• dsh-find-plugin: Conversational plugin search, like a shopping guide inside the store

These two paths complement each other. Let's explain each below.

dsh-market, Install an App Store

Installing it requires just one command:

dsh plugin --profile web add dshmarket

After installation, restart dsh web, and a Plugin Marketplace tab will appear in the settings panel. Clicking in, you'll see an interface like this:

The subtitle at the top of the page reads "Discover community-built capabilities for DeepSeek Harness · 595", meaning this marketplace has already cataloged nearly 600 community plugins, and it's still growing.

The entire interface is almost as intuitive as a mobile app store:

• Three tabs: Discover, Themes, Installed
• Category bar: UI Enhancement, Themes & Appearance, Model & Account Access, Sessions & Messages, Memory, Tools & Capabilities, Skill Packs, Workflow & Automation
• Sorting: Hottest, Newest, Earliest
• Search box: Top right, with the placeholder text "Search plugins, e.g.: notifications, skins"

Each plugin card displays the name, author, star count, description, category tags, and an Install button. Click install, confirm the source, and the progress is shown in real-time. Most plugins take effect upon refreshing the page, no restart needed.

Search is the Fastest Way to Find Plugins

For example, if you want to find skill-related plugins, type skill in the search box, and the list filters in real-time:

The search results list plugins like superdesign-skill, blender, skills, and others related to "skills." Category filtering and sorting can all be combined with the search.

Change the Theme While You're At It

The marketplace also has a dedicated Themes tab, making browsing themes even easier than browsing plugins:

Each theme is an independent plugin, taking effect immediately upon installation with a one-click switch. Themes are mutually exclusive, and your choice is preserved after a restart. dsh-deep-whale (whale girl series skins), dsh-skin, dsh-font, dsh-blue-whale are all great community creations.

Installed Plugins at a Glance

The Installed tab in the top right of the marketplace centrally displays all currently installed plugins and their versions:

Right after installing dsh-market, this will show dshmarket v1.4.1, with labels for "Usage Instructions" and "Up to Date." You can see at a glance what's installed and whether an upgrade is needed.

dsh-find-plugin, Let an Agent Find Plugins for You

Browsing the marketplace is good for "just looking around," but sometimes you only have a vague need: "I want a plugin that can do such-and-such." That's when dsh-find-plugin comes into play.

Installing it is also a single command:

dsh plugin --profile web add dsh-find-plugin

After installation, just tell the agent your need directly in a conversation, for example:

Help me find a plugin that can provide cross-session memory for conversations

The agent will search the plugin ecosystem directory by keyword and category, returning a list of matching plugins, each with a one-line description and an executable installation command. Copy the command to the terminal and run it, the plugin is installed. Go back to the interface, refresh, and it's ready to use.

Two images clarify the relationship between the two paths:

• The left path: Settings → Plugin Marketplace, browse, search, and install yourself
• The right path: State your need in a conversation, let the agent be your shopping guide, it gives you results and commands

Both paths lead to the same plugin repository, with a consistent data source, ensuring if it can be found, it can be installed.

A Must-Know Reminder

Installing a third-party plugin is equivalent to running third-party code on your machine with your permissions; it can read files, use credentials, and access the network. Tool approval does not sandbox plugin code. Therefore:

• Only install plugins from trusted sources
• Glance at the source code before installing
• Test unfamiliar plugins in an environment that does not hold keys first

The marketplace itself has a security design: it only allows installation of plugins listed in the community's curated list, rejecting other sources. This is equivalent to the shelf having already undergone a round of screening, but don't equate "listed" with "security audited."

E-book: Master dsh in 30 Minutes

If you're new to dsh and don't know where to start, I've compiled my complete introductory tutorial into an e-book:

From environment preparation, model configuration, and the first conversation, to permission approval, plan mode, and sub-agents, the chapter order follows the interface function order. Just follow along with the graphical interface and you'll learn it. The plugin ecosystem section is also included, with screenshots and hands-on steps.

Summary

• dsh-market: A visual plugin marketplace, installed with one command. Go to Settings → Plugin Marketplace, and browse nearly 600 plugins.
• dsh-find-plugin: Conversational plugin search, letting an agent find plugins based on your needs and return executable installation commands.
