dsh-file-path

The DeepSeek Harness Web composer accepts only PNG, JPEG, WebP, and GIF as attachments. Dropping a PDF, an archive, an Office document, or an entire directory into the composer currently triggers an images-only notice and the file is discarded. Browsers intentionally withhold the absolute host path of a dragged file for security reasons, so even a locally served page cannot recover it from the drag event.

dsh-file-path turns the local dsh process itself into a path-resolution bridge. After a non-image file is dropped, the browser computes a SHA-256 digest and calls the filePathBridge RPC on the dsh host, which searches the session workspace and configured roots by name, size, and hash to return the original absolute path, inserted directly into the composer. Nothing is copied or written to disk, so an 800 MB archive resolves in milliseconds. The plugin also supports dragging whole folders under Chromium-based browsers, a paperclip button for manually typing a path, and intelligent routing in mixed drops where images still flow through the default image intake.

It is aimed at two practical needs: users who interact with dsh through the Web UI but regularly need to reference local PDFs, code archives, or Office documents; and developers who want to paste a local directory path into a conversation without an extra upload or copy step. The plugin leaves dsh image handling untouched and simply adds a lightweight reference-by-path alternative for everything else.
