dsh-file-picker

DeepSeek Harness has long allowed the agent s read tool to follow absolute paths beyond the workspace, but the DSH Web UI lacked a simple interface entry point for getting file paths into a conversation. Manually pasting long paths is error-prone, browser drag-and-drop does not expose real file paths, and the input bar s plus button is already taken by the image attachment pipeline. dsh-file-picker fills exactly that gap.

The plugin adds a clip button to the input tool row; clicking it opens a native Windows file dialog where you can browse any directory outside the workspace and select multiple files at once. Selected files appear as an attachment rail with icons, file names, and parent directories, and can be individually removed. When you send the next message, the host process injects the absolute path list as a Context Injection message into the session, landing in the model context in the same turn as your message so the agent can immediately read the files with the existing read tool. Paths never enter the draft or the message text, and files are never read, uploaded, copied, or moved—all data stays on the local loopback interface.

It is built for Windows-based DeepSeek Harness Web users who need the agent to reference design documents, code in other repositories, or any file on disk without copying files into the workspace or typing long paths by hand. One click on the clip button hands the path to the agent cleanly and securely.
