dsh-plugin-marketplace is a plugin marketplace for DeepSeek Harness that lets developers browse and install plugins directly from the application UI.
The tool solves the friction of discovering and installing DeepSeek Harness plugins by embedding a searchable marketplace into the settings page. It queries the public GitHub search API to find repositories tagged with dsh-plugin, displays plugin cards with metadata like description and star count, and provides one-click installation. Users can search by keyword, sort by stars or update date, view README summaries in a detail panel, and ask the configured AI model to explain what a plugin does without reading documentation manually.
The marketplace suits anyone using DeepSeek Harness who wants to extend functionality without leaving the application or using the terminal. It works on both web and desktop versions of DSH, though desktop installation requires restarting the app to load the updated bundle. The tool requires DSH 0.2.0-rc.2 or later for the configuration page interface. It has no client-side dependencies beyond React and requires no build step, using a hand-written module loader bundle instead. The GitHub API integration is unauthenticated and rate-limited to 60 requests per hour, which is sufficient for typical browsing but may constrain heavy usage.
The project maintains active compatibility testing across DSH versions, with verified support documented for specific prerelease builds. Desktop installation handling was recently refined to resolve requests outside the settings transaction, retry transient state-write failures, and show progress feedback with a 15-second timeout for host acknowledgement. The tool respects the host DSH language setting for all UI text and configuration, with language switching preserving unsaved settings across the marketplace interface.
