The hard part of a fast-moving plugin ecosystem is rarely finding another project. It is deciding whether a project deserves a place in a working setup.
DeepSeek Harness is a developer preview with a plugin-first architecture, and its surrounding ecosystem already includes interface extensions, vision tools, workflow helpers, terminal experiences, and desktop clients. Those projects can be useful, but an install command is not a review process. A plugin may execute with local permissions and interact with files, credentials, networks, or shell commands.
That is why I prefer repository-first discovery.
DSH Hub is a bilingual directory for DeepSeek Harness plugins and clients. Its rule is simple: every listed item must point to a publicly reachable GitHub repository. The goal is not to turn a catalog into a trust badge. The goal is to make the source, ownership, license, release history, and installation material easy to inspect before an extension enters a Harness profile.
DSH Hub keeps clients and plugins in different groups.
A plugin usually adds a narrow capability to a running Harness profile. A client can do more: package a runtime, provide its own update path, expose a network listener, or ship a bundle of extensions. That difference changes what needs review. If both are listed as the same kind of tool, it is easy to miss the extra surfaces a client can introduce.
The August 18, 2026 catalog snapshot contains 19 plugins and 6 clients. Discovery starts with the official DeepSeek Harness repository, the GitHub dsh-plugin topic, and a community-maintained registry. Each selected repository is then checked for a clear, public connection to the ecosystem.
A short loop catches more than a long list of popularity signals:
If an extension cannot explain its permissions, update path, or external connections, the correct answer may be not to install it. DSH Hub uses "verified" in a deliberately limited sense: the public GitHub repository was reachable, and visible metadata was recorded on the snapshot date. It is not a security audit, a maintainer endorsement, or a guarantee that every published artifact matches the repository.
Stars are useful as a discovery signal. They are not evidence of compatibility or safety. The same is true for a polished landing page or a copy-pasted command from a social post.
A focused directory can make the first research step faster. It cannot replace technical judgment. Use dsh-hub.org to find a relevant project, then follow the link to GitHub and make the final decision from the source.
