dsh-drop-in

🌐 中文版：README.zh.md

Drag files from your system file manager straight into the DeepSeek Harness web GUI. Files appear as a chip bar above the input box, or — with the composer focused — as a native reference bubble (file pill) embedded inline in the text you are typing; they are sent along with your message (including their absolute paths), and render as file cards inside the user bubble. The agent reads the real file paths — no upload, no content copy (plain-browser fallback copies small files into the workspace).

Features

• 📎 Drag in any file/folder (images are treated as files — the official image-drop overlay no longer steals the drag)
• 🫧 Inline file bubble: dropped/pasted files are inserted at the caret as a native reference pill (works mid-text); the pill shows TYPE name (e.g. LNK 坚果云.lnk — the type survives name clipping, full name on hover)
• 📤 Path on send: the pill expands to a reference carrying the absolute path (@[filename](absolute-path)); the chat bubble renders it as a file card with a type badge — the agent can read the file straight from the path
• 🔀 Messages sent while the agent is running ("interrupt-free") render the same file cards
• 🖼️ Clipboard paste: pasting an image/file into the composer goes through the same pipeline instead of the native image-attachment rail; pasted binaries are persisted (base64) under .dsh-drops/<sessionId>/
• 🚀 Chip bar above the input: icon + name + size + path status, removable (×), deduplicated by path
• ✔️ Enter / Ctrl+Enter / the send button are all covered; chips clear automatically after sending
• 🔍 A dropped_files tool lets the agent list still-unsent dropped files
• 🖥️ Under DSH Desktop (Electron) absolute paths come from the preload bridge (webUtils.getPathForFile — the only path source in modern Electron)
• 🌐 Fallback: in a plain browser (no preload bridge) text files are copied to the workspace .dsh-drops/

Install

dsh plugin --profile web add https://github.com/lbl61/dsh-drop-in/archive/refs/tags/v1.4.0.tar.gz

Manual (bundle) install:

1. Extract dsh-drop-in into ~/.dsh/profiles/web/node_modules/dsh-drop-in/
2. Add "dsh-drop-in" to the dsh.profile.bundles array in ~/.dsh/profiles/web/package.json
3. Restart dsh web (DSH Desktop: quit fully and reopen, or run window.dshDesktop.restartService() in DevTools)

DSH Desktop: enable absolute paths (required for path features)

Absolute paths come from a preload bridge that lives in the DSH Desktop shell, not in this plugin. Modern DSH Desktop packs its preload into resources/app.asar, so a plain file patch no longer works — and every DSH Desktop update wipes the bridge. Run the bundled injector:

node scripts/install-preload-bridge.mjs      # auto-locates DSH Desktop
node scripts/install-preload-bridge.mjs --dry-run   # check only
node scripts/install-preload-bridge.mjs --restore   # undo (byte-identical)

Then fully quit and reopen DSH Desktop. Without it, chips still appear but read "无法读取路径" (no path) and the agent cannot read the files. See preload-bridge.md.

For a plain browser (no Electron shell) there is no bridge by design; text files fall back to being copied into .dsh-drops/<sessionId>/ in the workspace.

Usage

1. Drag files from Explorer into the chat page (or paste an image/file into the composer)
2. Composer focused → files are inserted at the caret as native reference bubbles (file pills), mid-text allowed; otherwise they appear in the chip bar above the input
3. Type your message and send (Enter / Ctrl+Enter / the send button all work; "interrupt-free" sending while the agent runs is supported too)
4. The bubble shows file cards — the agent receives the absolute path (@[name](path) or the 📎 拖入文件 block) and can read the files

How it works

• The client half intercepts file drags in the capture phase (the official image-upload flow never steals the events), keeps a per-session chip bar (conversation.input.dock), renders user bubbles with file cards (conversation.chat.node user/steering keys), and stitches the 📎 拖入文件 block into the draft before submit (Enter, Ctrl+Enter, and the send button are all covered); with the composer focused it inserts native reference bubbles via the slash/input-insert-reference scoped event (U+FFFC occurrences rendered by the composer backdrop) and the registered inputTriggers codec serializes them to @[filename](absolute-path) on submit
• The host half keeps the per-session file registry behind the dropped_files tool, writes fallback text copies to .dsh-drops/<sessionId>/, and persists pasted binaries via the file-copy route (base64, with an explicit workspace-write sandbox policy rooted at the session cwd)
• Absolute paths under DSH Desktop rely on the preload bridge (see preload-bridge.md): Electron ≥ 32 removed File.path

Configuration

Uninstall

1. Remove dsh-drop-in from the dsh.profile.bundles array in ~/.dsh/profiles/web/package.json
2. Delete ~/.dsh/profiles/web/node_modules/dsh-drop-in/
3. Restart dsh web
