DeepSeek Harness Plugin: dsh-files-pane — Browse and Read Files Online

`dsh-files-pane` is a web plugin for DeepSeek Harness (DSH) that addresses the issue of file links not opening in headless host environments. It adds a "Files" tab to the chat interface, supporting two-pane directory navigation, relative image rendering, and Markdown/code highlighting. Users can browse files directly in the browser, and clicking a file reference automatically navigates to it. The plugin is installed via a package manager and requires a service restart after installation. It limits text files to 400 KB and images to 4 MB, and does not support direct display of binary files.
