What to Check Before Installing

WhereWhat to look for
Security signalsRisks our scan found and how severe they are, on each plugin page
Repository activityLatest commit and release. A plugin untouched for six months is a warning sign on a fast-moving preview
CompatibilityThe profile it targets (web, desktop) and DSH versions it was tested with
Install commandCopy it from the plugin page; the package name and repository name differ for many plugins
12

Install and Remove

Restart dsh web after installing. The desktop app installs from its own Plugins page. Profiles, Git specs and troubleshooting are in the install guide.

Install into the web profile
dsh plugin --profile web add <package>
Remove
dsh plugin --profile web remove <package>

FAQ

Do more plugins make DeepSeek Harness slower?

+

Every plugin loads when DSH starts, and interface plugins also run in the browser. More plugins mean slower starts and more chances of conflicts. Remove the ones you do not use.

Can plugins conflict?

+

Yes. The usual cases are two skins or two sidebars changing the same part of the screen, or two plugins claiming the same command. Disable the latest one first.

How are these different from built-in plugins?

+

DeepSeek Harness itself is built from official plugins; the Web UI, skills and themes are all plugins. The ones here are community plugins maintained by their authors, not reviewed by DeepSeek.

Do these work in the desktop app?

+

Most target the web profile. The desktop app has its own desktop profile, and you install from its Plugins → Add plugin page. Plugin pages show the profile the author declared.

When is this list updated?

+

Stars and install commands update live from the Registry. Groups and reasons are reviewed as new plugins appear; the date is at the top of the page.

Primary sources

This guide is grounded primarily in the current DeepSeek AI Harness repository and development documentation. Harness is still in developer preview, so exact commands and contracts can change with later releases.
