DSH Marketplace

An open-source plugin marketplace for DeepSeek Harness (DSH). Browse, search, and install community plugins with one copy-paste dsh command.

Everything in DSH is a plugin. This marketplace is the storefront: a verified, auditable index of plugins you can install straight into your dsh profiles.

✨ Features

• Static, auditable registry — every plugin is a small JSON file (registry/plugins/<id>/plugin.json) reviewed through a normal GitHub PR. No database, no server to run.
• One-command install — every plugin card gives you the exact install command with your choice of profile (web, headless, custom), honoring DSH's real plugin mechanism: dsh plugin --profile <name> add <spec>.
• Supports all DSH install sources — npm packages, Git-hosted plugins (github:owner/repo), and local paths.
• Verified badge — maintainers/community can mark a plugin verified after review, following a governance model similar to curated marketplace projects.
• Search & categories — instant client-side search over names, descriptions, tags, and maintainers, plus category filtering (Skills, Tools, Web, Infrastructure, Integration, Workflow, Experimental).
• Self-hostable — pure static site. npm run build, then host web/dist anywhere (GitHub Pages, Netlify, Nginx, etc.).
• Fast — the UI loads a single gzipped index.json.
• In-harness plugin — the repository also ships a real DSH client plugin (plugin/client/) that renders a Marketplace tab inside Settings → Plugins of the DSH web GUI, so you can browse the catalog from within the harness itself.

🧩 How DSH plugins work (the model we build on)

DSH is built on Cordis: everything is a plugin. Plugins are npm packages managed by pnpm in a profile directory. To install one:

# npm package
dsh plugin --profile web add some-plugin-package

# Git-hosted plugin
dsh plugin --profile web add github:owner/repo

A plugin contributes a config layer by declaring "dsh": { "bundle": { "patch": "./cordis.patch.yml" } } in its package.json; when installed, dsh wires that patch into the profile's dependency stack automatically. Discoverability uses the dsh-plugin GitHub topic. This marketplace indexes those plugins so people can find them.

🚀 Getting started

Requires Node.js ≥ 18 and a recent dsh installation.

# 1. Install dev dependencies (Vite + React)
npm install

# 2. Validate the registry
npm run validate

# 3. Regenerate the combined index and build the static site
npm run build

# 4. Serve the built site locally
npm run serve       # dev server on :5173
npm run preview     # preview the production build on :4173

Open http://localhost:5173 in a browser.

Deploying

The build outputs a fully static site to web/dist. Host it anywhere static files are served:

npm run build
# then upload web/dist/ to your host, or use the included GitHub Actions workflow

The homepage and plugin entries live in registry/. The index.json (and .gz companion) are regenerated on npm run build and can be committed so the site works immediately after clone.

🧩 In-harness Marketplace tab (client plugin)

The repository ships a real DSH client plugin under plugin/client/ that renders a Marketplace tab inside Settings → Plugins of the running web GUI. It mounts into the shared settings.plugins.tab slot and shows the embedded catalog with search and per-plugin install commands — fully offline.

To install it into a profile (e.g. web):

pnpm add file:./plugin/client            # from the repo root
# then add a plugin row to "$DSH_HOME/profiles/web/cordis.patch.yml":
#   - insert:
#       - id: dsh-market
#         name: '@dsh-marketplace/dsh-market'
# and restart the web profile (pnpm dsh web)

Client plugin metadata is cached until restart, so a profile restart is required after adding it. Building the bundle from source requires the DSH workspace toolchain (tsdown + the @deepseek-ai workspace packages); the built lib/client.js is committed so install works without a rebuild. See plugin/client/README.md.

🧱 Verifying install commands

Install commands are synthesized from each manifest's install field. Under the hood DSH resolves them to real dsh plugin --profile <name> add <spec> calls, which forward to pnpm. Git-hosted plugins that ship sources build during install via their prepare script; if a pnpm allow-build prompt appears, copy the printed key into the profile's pnpm-workspace.yaml and re-run (see the DSH reference docs).

📐 Registry schema

Each registry/plugins/<id>/plugin.json follows schema/plugin.schema.json. Minimal example:

{
  "id": "my-plugin",
  "name": "My Plugin",
  "version": "1.0.0",
  "description": "What it does.",
  "author": { "name": "you", "url": "https://github.com/you" },
  "license": "MIT",
  "category": "tools",
  "tags": ["example"],
  "compatibility": { "dsh": ">=0.1.0", "platforms": ["linux", "macos", "windows"] },
  "install": {
    "target": "npm",
    "spec": "my-plugin",
    "command": "dsh plugin --profile {profile} add my-plugin"
  },
  "verified": false,
  "repository": "https://github.com/you/my-plugin"
}

install.target is one of npm | git | local. {profile} is replaced by the user's profile of choice (default: web). See CONTRIBUTING.md to add a plugin.

🌱 Design inspiration

This project synthesizes good ideas from the growing community around DSH:

• Verified / auditable registry — inspired by curated plugin-marketplace efforts (dsh-plugin-marketplace) that gate listings behind review.
• Static, PR-reviewable JSON index — from the "thin console over a static registry" approach used by community registry tooling, keeping the source of truth in Git.
• Visual browse/search/install UI — from visual plugin marketplaces, adapted to DSH's real dsh plugin add install path.
• Scenario-first categories (skills like TDD/debugging/planning) — from curated skill collections such as superpowers-dsh.
• dsh-plugin topic discoverability — lifted from the official DSH contributing guide.

🤝 Contributing

Yes, please! Add your plugin, improve the UI, or fix docs.

• Add a plugin: create registry/plugins/<id>/plugin.json and open a PR. Full guide in CONTRIBUTING.md.
• Governance: statuses like verified are assigned by maintainers after review; a successful CI run (npm run verify) is required to merge.
