dsh-file-explorer

A purely text-based model cannot see files. If you want your DeepSeek Agent to review a config or tweak a snippet, you still have to cat it in a terminal, paste it into the chat, then switch back when the result comes. dsh-file-explorer folds that entire loop into the Harness interface: a floating button in the bottom-right corner opens a file tree, a single click on any file auto-switches to a Preview/Edit tab sitting alongside Conversation and Trajectory, and a double-click drops you straight into an editable textarea. Save with Ctrl+S, no window-hopping.

Beyond viewing and editing, it smooths out the act of referencing. Drag any entry from the file tree into the message input and the absolute path drops in on release, ready for the Agent to pick up with a read tool. Creating new files and deleting existing ones happen right in the tree; folder deletion requires an explicit irreversible-action checkbox plus server-side guards that reject non-empty directories and the filesystem root, so a stray click cannot wipe your workspace.

Who is it for? If you live in the Harness Web UI and your working directory is a mix of source files, images, and configs that you reference, inspect, or modify mid-conversation, this plugin keeps all three actions on a single page. It ships as a pre-built bundle requiring only the Harness Web profile and a restart to activate, with no extra build step on the consumer side.
