10 Must-Have Plugins for DeepSeek Harness: Complete Installation & Usage Guide

Introduction

DeepSeek Harness (DSH) is a powerful AI agent platform, but its full potential is unlocked only when you install the right plugins. This guide covers 10 essential plugins that will transform your DSH experience, from UI customization to multi-agent collaboration. We'll provide exact installation commands and practical usage instructions for each plugin.

UI & Experience Enhancement Plugins

1. dsh-web-ui-all (Theme & UI Plugin)

This popular plugin completely transforms DSH's appearance with beautiful themes, desktop pets, and advanced UI features.

Installation Commands:

npm install -g @deepseek-ai/dsh @deepseek-harness/tui/
dsh-tui

Usage: Run dsh-tui in your terminal to enter the command-line programming environment, similar to Claude Code or Codex CLI.

3. dsh-better-sidebar (Sidebar Plugin)

Adds a powerful sidebar for real-time project file viewing and navigation.

Installation Command:

Usage: The sidebar appears on the left, allowing you to browse files, access command-line tools, view browser pages, and monitor project development results.

Productivity & Development Plugins

4. dsh-lark-channel (Feishu/Lark Integration)

Connect DSH with Feishu/Lark for seamless team collaboration.

Installation Commands:

npm install --global dsh-lark-channel@0.0.6
dsh-lark-channel start --profile lark --workspace "SPWD"

Usage: Scan the QR code to bind your Feishu account. Once connected, you can control DSH through Feishu messages, use commands to switch directories, call skills, and manage tasks.

5. dsh-archify (Architecture Diagram Generator)

Automatically generates beautiful architecture diagrams from code repositories.

Installation Command:

dsh plugin --profile web add @tt-all/archify-dsh@0.1.0

Usage: Simply prompt the plugin to generate architecture diagrams, workflow charts, or sequence diagrams. It outputs interactive HTML with features like section navigation and multi-format export.

Agent Performance Boost Plugins

6. dsh-design (Vibe Design Plugin)

Open-source alternative to Claude Design for AI-powered design work.

Installation Command:

dsh plugin --profile web add deepseek-design@0.2.2

Usage: After installation, restart DSH and find the "Design" tab in the conversation window. You can edit designs directly, modify pages, or export as HTML.

7. dsh-prompt-enhancer (Prompt Optimization)

Automatically enhances and optimizes your prompts for better agent performance.

Installation Command:

dsh plugin --profile web add github:fsisb/dsh-prompt-enhancer#3.15

Usage: Write your prompt, then use the plugin to optimize it. You can perform multiple rounds of optimization until you're satisfied.

8. dsh-openviking (Memory System)

Adds persistent memory management to DSH agents, making them "smarter" over time.

Installation Commands:

CMAKE_ARGS="-DGGML_METAL=ON" uv tool install --force --python 3.12 --with xhash<4" openviking[local-embed] =0.4.14"
dsh plugin --profile web add @github/volcengine/OpenViking/path=/examples/dsh-memory-plugin

Usage: The plugin works in the background, remembering your preferences and past interactions. Test it by telling the agent something (e.g., "I like iced American coffee") and then asking it later.

9. dsh-modlens (Vision Enhancement)

Adds visual capabilities to DSH agents, allowing them to analyze images.

Installation Commands:

npx -y @deepseek-ai/dsh plugin --profile web add @ilustack/modlens@1.6.6
npx -y @ilustack/modlens config set provider openai
npx -y @ilustack/modlens config set openai.baseurl "https://dashscope.aliyuncs.com/compatible-mode/v1"
npx -y @ilustack/modlens config set openai.model qwen3-vl-plus
export DASHSCOPE_API_KEY="your-api-key"
export OPENAI_API_KEY=$DASHSCOPE_API_KEY

Usage: Upload images and the agent will analyze them using the visual model.

10. dsh-agent-teams (Multi-Agent Collaboration)

Create and manage teams of agents for complex tasks.

Installation Command:

dsh plugin --profile web add @nanmicoder/dsh-agent-teams

Usage: Describe your task and the plugin will automatically create a team of agents (e.g., product designer, developer, security reviewer) that collaborate to complete the task.

常见问题

Do I need to install all 10 plugins at once?

No. The plugins are independent, so you can install only the ones that fit your workflow. If you live in the terminal, start with dsh-tui and dsh-better-sidebar. If you mostly work in the browser, begin with dsh-web-ui-all for the theme and desktop pet experience. The performance plugins (dsh-design, dsh-prompt-enhancer, dsh-openviking, dsh-modlens, dsh-agent-teams) each add a distinct capability, so install them as you need that capability rather than all upfront.

Are these plugins free and open source?

Yes, they are all community plugins in the DeepSeek Harness ecosystem and are free to install. They are managed through the dsh plugin command or DSH Studio, and several are explicit open-source alternatives — dsh-design is described as an open-source alternative to Claude Design, and the source for each project is available on GitHub. The only external dependency is when a plugin needs an API key, such as dsh-modlens using DashScope for the vision model.

Which plugins give the biggest boost for agent performance?

For raw capability, dsh-modlens (vision) and dsh-openviking (persistent memory) change what the agent can do, not just how it looks. dsh-prompt-enhancer improves every prompt you feed it, which compounds across tasks. dsh-agent-teams scales single agents into a collaborating team for complex projects. If you had to pick a shortlist: dsh-web-ui-all for the interface, dsh-openviking for memory, and dsh-agent-teams for multi-agent work are the three with the most visible day-to-day impact.

Do I need to configure plugins after installing them?

Some yes, some no. Pure UI plugins like dsh-web-ui-all, dsh-tui, and dsh-better-sidebar work right after install. Plugins that call external services need configuration: dsh-lark-channel requires scanning a QR code to bind Feishu, and dsh-modlens needs provider settings plus a DashScope API key. Follow the exact commands in each section above — the configuration steps are part of the install snippet for the plugins that need them.
