dsh-drag-and-drop — Drag local files in and insert their real paths

Install: dsh plugin --profile web add github:omdsh-dev/dsh-drag-and-drop

A DeepSeek Harness Web UI plugin: drag local files or folders onto any part of the page and their original absolute filesystem paths are inserted into the current conversation input — without uploading, moving, or copying anything.

Why this exists

A browser never hands a web page the real filesystem path of a dropped file — it exposes only a local file URI when it feels like it, and often nothing at all, for security. DSH, though, operates on real files: its tools read, run, and patch actual paths on the machine. Drop a file into an ordinary web input and you get either an upload (a copy that silently breaks the file's relationship with its neighboring dependencies) or a hand-typed path that is easy to get wrong.

This plugin closes that gap on the machine running DSH. It converts the browser's local file URI into the native absolute path, and when the browser hides the path entirely it resolves the file back to its real location — through the current Workspace, registered Workspaces, the OS file index, and a bounded directory search — then writes that path into the current conversation input. The file never leaves its directory.

Features

• Drag files onto any part of the Web UI to insert their original absolute paths
• Full-page dim + blur hint while dragging
• Supports files and folders; drag multiple items at once — one path per line
• Native paths on macOS, Linux, and Windows
• POSIX paths, Windows drive-letter paths, and UNC network paths
• No uploading, moving, or copying of files
• Locates files in the current Workspace and registered Workspaces first
• When the browser hides the original path, uses the local file index and bounded directory search
• Computes content fingerprints only when multiple candidates exist
• When several byte-identical copies cannot be told apart automatically, lets the user pick the path
• Failed lookups surface as a dismissible plugin toast (auto-dismisses after 8s; hovering pauses the timer)
• Writes the draft via DSH's input-state service instead of touching the input DOM

Usage

Drag files or folders from Finder, a Linux file manager, or Windows Explorer onto any part of the DSH Web UI.

Release the mouse when the full-page drag hint appears; the plugin writes the resolved original absolute path into the current conversation input.

Dropping multiple items at once inserts one path per line.

Install

The plugin is a DSH bundle (package.json declares dsh.bundle + dsh.client). Install it into the web profile with the standard dsh plugin mechanism — no DSH source changes and no config.yaml needed:

dsh plugin --profile web add github:omdsh-dev/dsh-drag-and-drop
# or from a local checkout:
dsh plugin --profile web add /path/to/dsh-drag-and-drop

The repository ships its build output (lib/ is committed) — no build step needed after installing.

The old README's pnpm --filter @deepseek-ai/dsh add ... + config.yaml flow is obsolete: under the official profile/bundle model config.yaml is no longer read.

After installing, restart the Web UI the way you normally start DSH, then refresh the browser page — the plugin appears in the browser boot manifest (__DSH_BOOT__) and its client bundle loads automatically.
