dsh-plugin-marketplace

The DeepSeek Harness plugin ecosystem lives across a GitHub dsh-plugin topic, so adding a new plugin usually means hunting through repos, guessing install commands, and wrestling with pnpm edge cases. dsh-plugin-marketplace turns that scattered landscape into a unified marketplace inside the settings panel: page through every plugin, search by keyword, check star counts and descriptions, and kick off a deterministic async install with a single button click—all without leaving the Harness UI.

The install pipeline is heavily engineered. Repository shape is auto-detected: plugins published to npm are installed via npm for speed and reliability, monorepos are cloned, built with corepack pnpm, then registered via link, while root-level plugins follow the standard dsh plugin add path. A live progress bar shows stage, percentage, download speed, ETA, and real-time logs, with a cancel button at any point. When pnpm major-version drift, pre-release peer dependencies, missing workspaces, or stalled downloads occur, the plugin surfaces actionable diagnostics and auto-retries instead of dumping a bare exit code. If direct install still fails, a fallback button lets the agent open a dedicated workspace, read the README, and decide the install strategy on its own, without polluting the current session.

Four host-side tools (market_search, market_install, market_installed, market_update) are registered so the model can autonomously discover, install, list, and update plugins mid-conversation. The installed tab supports version comparison, one-click updates, enable/disable, and uninstall, while the marketplace itself checks for its own updates and shows a banner. It is built for anyone running DeepSeek Harness who wants to quickly find, install, and manage third-party plugins, as well as developers who want their agents to self-extend with new capabilities.
