DragView

Referencing a local file inside a DSH chat session used to mean either pasting a file path by hand or copying the file into the workspace before telling the model where to look. DragView compresses both steps into a single drag-and-drop: pull a file from your file manager into the chat window and release. Based on the mode you chose — resolve looks up the real path without touching the original file, while copy duplicates the bytes into the workspace — a Codex-style attachment card appears above the input box, showing a type icon, the file name, its size, and a remove button.

Click the card to preview PDFs, plain text, code, video, and audio directly inside DSH; Office documents, archives, and other types open in the system default application. When you send the message, a plain-text file reference is prepended so the model can read it, yet the absolute path never leaks into the attachment DOM, the page title, or the browser console.

The plugin is aimed at engineers and researchers who routinely ask a DSH model to work with local source code, documents, or media. It deliberately leaves image attachments to the platform native pipeline and focuses on one job: getting a local file into the conversation context safely and cleanly. Path resolution walks through five progressive layers — registered workspace, system directories, shallow scan, OS index, and bounded recursion — and every preview or open call re-verifies the file identity so you are always looking at the exact file you dragged in.
