What it is — The plugin panel is a sidebar bottom entry in the DeepSeek Harness Web GUI. Clicking it opens a right drawer for searching, favoriting, and managing community plugins, skills, client UIs, and development resources, with install, update, and uninstall via the official CLI.
Who it is for — When using DeepSeek Harness Web GUI to explore community plugins, skills, client UIs, or development resources, this plugin provides a sidebar entry and right drawer with keyword and semantic search.
If you only want to use built-in plugin management without needing an additional sidebar entry and right drawer, you do not need to install this plugin.
Watch out — Installation requires restarting the GUI to take effect. It was tested to register successfully in a new profile. No obvious pitfalls were found.
The verdict — I would install it because it supports semantic search with BAAI/bge-m3 and installed state tracking, but only if using DeepSeek Harness Web GUI for plugin management.
