dsh-file-upload

DSH Web's built-in drag-and-drop story falls short in practice. When the active model does not support vision, dragged images are rejected outright; there is no single archive you can browse later; and pulling a previously uploaded file back into a new conversation means digging through chat history. dsh-file-upload solves all three at once. It adds a theme-aware upload button to the composer tool row and intercepts window-level drag events, so the most natural gesture—dropping a file from your desktop—just works. Supported images (PNG, JPEG, WebP, GIF) ride the official DeepSeek Files API attachment rail with automatic file_id reuse and 7-day-expiry re-upload. Every other file type is archived into the attachment library and a path line is injected into the draft. Dragging an entire folder recursively reads the tree, rebuilds it under the library preserving the original directory layout, and inserts a single folder path into the draft. When the model cannot display images, the plugin degrades gracefully to path text so no 400 error is ever raised. The v0.2.0 release further adds an in-settings-card file management panel with paged browsing, one-click @path copy, and safe deletion, plus zero-copy clipboard path reading: copy a file or folder in your OS file manager, click the clipboard button next to the upload icon, and the real system path is inserted as an @ reference in the draft with no disk copy and no size limit.

Who is this for? Power users who build prompts around local code, docs, screenshots, or binary assets and want a friction-free path from file manager to conversation. If you maintain a growing library of reference materials and expect to revisit them weeks later, the date-organized archive plus the settings-card browser keep everything a click away. The plugin is pure Node under the hood (only the clipboard feature shells out to a platform tool), works on macOS with full testing and is expected to run on Linux and Windows, is released under the MIT license, and is independently maintained by the community—no official DeepSeek involvement required.
