Awesome DSH Plugin

A curated guide to DeepSeek Harness (dsh) — DeepSeek's open-source, everything-is-a-plugin coding agent — and the best community plugins built on it.

DeepSeek Harness is a runnable coding agent (Web UI + headless) built on Cordis, where every part of the system — models, tools, sandboxes, session storage, UI, even the agent loop itself — is a swappable plugin. That architecture has produced a large, fast-moving plugin ecosystem: well over a thousand community plugins at last count. This list exists to make that ecosystem easy to scan: what a plugin does, in one line, sorted into the category you'd actually go looking under.

[!WARNING] Installing any third-party dsh plugin runs its code on your machine with your own permissions. Being listed here is not a security review — read the source before installing, especially for plugins that touch credentials, the network, or your filesystem.

What is DeepSeek Harness?

deepseek-ai/deepseek-harness is DeepSeek's open-source agent harness, currently in developer preview. Its defining idea is everything is a plugin: the model provider, the sandbox, the tool set, the session store, and the UI are all plugins loaded into a Cordis-based runtime, so you can replace or extend any layer without forking the harness itself. Plugins declare a dsh.bundle manifest and install with:

dsh plugin --profile web add <plugin-name>

Getting Started

# run the Web UI (served at http://127.0.0.1:3080 by default)
npx @deepseek-ai/dsh web

# or from a source checkout
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness && pnpm install && pnpm run build && pnpm dsh web

Tag your own plugin repo with the dsh-plugin GitHub topic so it's discoverable, and consider a plugin browser for one-click install/upgrade from inside the Web UI.

UI Enhancements

• 0xsline/dsh-spotlight — Keyboard-first command palette for the DSH Web UI.
• 1123762794/dsh-web-restart — Sidebar footer button that restarts the dsh web process and persists across the restart it triggers.
• 13071301808/dsh-composer-expand — Expand/collapse toggle that grows the composer to a tall 70vh writing view for long drafts.
• a179-sanae/dsh-auto-collapse — Codex-style auto-collapse: finished turns fold into a single summary row, fully reversible on uninstall.
• a735624258/dsh-skill-picker — Searchable skill picker beside the composer that inserts the official /skill-name gesture.
• a903067276-rgb/dsh-hud — HUD panel: Git status, MCP servers, skills, model and token usage, all floating.
• a903067276-rgb/dsh-file-mentions — Clickable file paths in replies, with reveal-in-file-manager and a mentioned-files chip list.
• AcidGr/dsh-web-lan-access — Fixes the Web UI so it survives LAN or Tailscale direct-IP access.
• AKS1st/dsh-mermaid — Renders Mermaid fences as sanitized, theme-aware SVG diagrams.
• AKS1st/dsh-sysmon — Floating CPU/memory/disk widget with threshold color warnings.

• Ricketts-Guo/dsh-shortcuts — 34 pre-registered keyboard shortcuts (sessions, views, clipboard, models, silent permission cycling), one-click recording to bind your own.
• Nagi-ovo/dsh-visualize — In-conversation generative UI: the model renders interactive HTML cards into the chat stream, with streaming preview and sandboxed rendering.
• PerryLink/dsh-budget — Cost governance: aggregated token/cost metering per model, session and day, session/daily/monthly caps with threshold alerts, alert/block/degrade over-limit policies, carbon estimation, and the /budget command.
