Open & browse the DSH plugin market in DeepSeek Harness

The DSH plugin market in DeepSeek Harness lives in Settings → Plugin Center: install DSH Plugin Hub, open the entry, browse curated community DSH plugins by card, category, search and sort, then click Install, confirm, and the plugin is installed in one click — no terminal commands required. Compared with dsh plugin --profile web add <package> on the command line, the market turns the same job into visual buttons; this guide breaks down the entry, browsing and installing steps one by one.

Overview: the plugin market at a glance, four things in one table

The plugin market concentrates four tasks — enter, browse, install, verify — behind a single entry on the Settings page. The market is the official storefront of DeepSeek Harness, hosting curated community plugins (source):

Each stage below offers multiple ways — pick whichever fits.

Entering the plugin market: two ways

The entry is Settings → Plugin Center, and the prerequisite is having DSH Plugin Hub installed; a fresh environment and an existing one take different routes. Two ways:

Way 1: fresh environment — install DSH Plugin Hub from the command line first

If you have never installed the Plugin Center, one command brings the market itself in. Prerequisite: DeepSeek Harness is installed and has been started at least once. Steps:

1. Open a terminal and run the install command:

# Install DSH Plugin Hub (npm package name, source in the official repo)
dsh plugin --profile web add dsh-plugin

2. Wait for npm to finish downloading; a success message appears;
3. Restart the dsh web service (npx @deepseek-ai/dsh web or restart your host);
4. Open the Web UI, go to Settings, and click Plugin Center in the sidebar.

Fallback: a 404 means a mistyped name or a stale mirror — confirm the package with npm view dsh-plugin, then switch the npm mirror and retry.

Way 2: Hub already installed — open the Web UI directly

Once the Hub is in place, every visit follows the same path with no commands involved. Prerequisite: DSH Plugin Hub is installed and active after a restart. Steps:

1. Open the DeepSeek Harness Web UI (the local service address, e.g. http://127.0.0.1:3080);
2. Go to Settings;
3. Click Plugin Center in the sidebar to enter the plugin market.

Fallback: if Plugin Center is missing from Settings, the Hub is probably not installed or not active — redo Way 1, restart and refresh; if it persists, run dsh plugin --profile web list to confirm the plugin is really there.

Browsing the plugin market: cards, categories, search, sorting

The market is a card list where every card answers "what is it, can I install it, is there a new version". The screen has three zones from top to bottom (source):

1. Top navigation: Plugin Center / Installed / Custom install / Settings, with a language switch on the right;
2. Toolbar: a search box, a result count and a sort button group (Name / Recent / Stars / Forks — click the same button to toggle ascending/descending);
3. Category filters: All / Installed / Not installed, to see only plugins you have not installed yet.

Each card shows the plugin name, version, installed and update badges, category, verified badge, description, topics, and star/fork/update timestamps. Three ways to browse:

1. By category: click the Not installed filter to see only plugins missing from your environment and avoid repeats;
2. By keyword: type a plugin name or a feature word (e.g. memory, translate) into the search box — the list filters as you type;
3. By popularity: click Stars to put the most popular first; click again for reverse order.

Open details takes you to the plugin page with the full intro and install command.

Installing a plugin: market one-click vs. the command line

The market and the command line install the same plugin to the same result — the difference is only in how you operate: buttons vs. commands. Two ways:

Way 1: one-click install from the market (recommended for beginners)

Find the plugin, click Install, check the confirmation dialog, confirm, and the live progress runs to completion. Steps:

1. Find the target plugin in the card list and click Install;
2. Read the confirmation dialog: the plugin name, source repo and the exact dsh plugin add command are shown — confirm only after verifying them;
3. Wait for the live progress: tasks run in a serial queue, the dialog shows progress and can be cancelled;
4. Done: the card button turns into "Installed", and the plugin takes effect after refresh.

Installing a plugin you already have switches to an "Update" meaning and reinstalls it in place to the latest version when one is detected (source).

Way 2: command-line install (for scripts and batch work)

When you would rather skip the UI, the command does the same job. Prerequisite: you know the package name. Steps:

# The command-line equivalent of a market install
dsh plugin --profile web add <package>

Confirm it appears with dsh plugin --profile web list. Fallback: a mistyped name returns 404 — verify with npm view <package> first.

Troubleshooting common issues

Look at the symptom first, then fix accordingly. Common issues:

If you cannot pinpoint it, open Settings → System logs for the full error and follow the matching guide.

Quick recap

In short: install the Hub, go to Settings → Plugin Center, browse the cards and click Install — no commands involved. Four reminders:

1. Install DSH Plugin Hub first: dsh plugin --profile web add dsh-plugin opens the entry in one command;
2. Three browsing moves: filter Not installed + search keywords + sort by Stars — combine them for the fastest result;
3. Check the confirmation dialog before installing: verify the plugin name, source repo and the command that will run;
4. Refresh and verify after installing: the card flips to Installed, the badge increments, or re-check with dsh plugin --profile web list.
