dsh-file-upload

Windows file upload for DeepSeek Harness: a configurable hotkey opens the native Windows file dialog (via PowerShell 7, with a labeled Windows PowerShell 5.1 fallback), then a graphical chooser lets you copy files into the workspace, insert a safe file list into the composer, or both. The UI is bilingual (中文 / English). Privacy is protected by default — see Privacy.

⚠️ Windows-only. Requires PowerShell 7 (recommended) or the built-in Windows PowerShell 5.1.

Features

• Hotkey: Ctrl+Shift+U by default — record any combination from Settings (click the key, then press the new one; Esc cancels).
• Reliable & simple: every pick spawns ONE short-lived PowerShell process (no persistent server — that design hung in some environments and was removed). Engine paths are resolved without probe processes, and every wait has a hard timeout, so the pick can never hang.
• Engine discovery: PowerShell 7 first (MSI → PATH → where pwsh → Store alias → Chocolatey), Windows PowerShell 5.1 as a clearly-labeled last resort. Each path is tried until one actually runs; the result is cached.
• Three upload modes (graphical, no code switching):
  • 📁 Copy to workspace — files land in <workspace>\uploads\ (name collisions become name (1).ext); the agent can read them.
  • ✏️ Insert into input — a safe file list is added to the composer.
  • 🔀 Both — copy and insert workspace-relative paths.
• Bilingual UI: 中文 / English, switchable in Settings → File Upload.
• Privacy controls — see below.

Privacy

The plugin never reads file contents and never scans your disk. What it handles:

Data	Where it goes
Selected file paths	Your browser only (modal + the copy request over loopback RPC)
Copied files	Your workspace <workspace>\uploads\ only
Text inserted into the composer	Your next message — controlled by settings below

Default-safe behaviors (all user-configurable in Settings → File Upload → Privacy):

• The modal lists file names only; full paths require an explicit "Show full paths" reveal.
• Text inserted into the composer never contains absolute paths unless you opt in: it uses workspace-relative paths (e.g. uploads/foo.txt) when the file was copied into the workspace, and bare names otherwise.
• The setting Insert absolute paths (default OFF) switches insertion to full paths; when ON, the upload modal shows a warning that absolute paths will be sent with your message to the model.
• At upload time the modal always shows a notice explaining where files go and whether absolute paths are included.

Nothing is sent to any network or model except what you deliberately place in the composer.

Install

See docs/INSTALL.md for both loading paths (dynamic session load and host-composition mount) and cordis.row.yml for the composition row.

Quick start (dynamic load in a session):

1. Read src/host/body.js → paste as code.host of a new Cordis plugin.
2. Read src/client/body.js → paste as code.client.
3. cordis_run and approve the client half.

Development

npm test            # unit + drift tests (zero-dependency runner)
npm run sync:assets # after editing assets/*.ps1, re-embed them into src/host/body.js

Layout:

src/host/body.js      # Host half: spawn-free engine discovery, one-shot spawns, hard timeouts
src/client/body.js    # Client half: i18n, privacy-safe flows, chooser/settings UI
assets/*.ps1          # Canonical PowerShell scripts (pick / copy)
tests/                # node tests/run-tests.mjs — fake-driven + real-pwsh integration
scripts/sync-assets.mjs

The two body.js files are plain-JS dynamic-plugin bodies (no imports), which makes them loadable through the cordis dynamic tools and testable in Node. The PowerShell scripts live in assets/ as the reviewable source of truth; tests/drift.test.mjs fails if the embedded copies drift.

Troubleshooting

• "open dialog failed" — the first pick pays engine discovery (~1s); later picks reuse the cached path and are faster. The error text names the failing step; the engine discovery is spawn-free and every step has a timeout.
• Store-installed PowerShell — the discovery chain resolves the Microsoft Store alias (%LOCALAPPDATA%\Microsoft\WindowsApps\pwsh.exe) automatically.
