dsh-mobile

Use DeepSeek Harness from your iPhone / iPad: LAN reverse proxy + iOS PWA (add-to-home-screen) + touch/mobile CSS for the web GUI.

中文

DeepSeek Harness's web GUI binds to 127.0.0.1 by default (upstream deliberately rejects --host 0.0.0.0 for safety). This plugin adds a first-class mobile experience:

• 📱 LAN access — the plugin runs its own 0.0.0.0 reverse proxy that forwards phone/iPad traffic to the loopback server, rewriting Host/Origin so the /api trust fence accepts it (HTTP and WebSocket upgrades included). The LAN URL and a terminal QR code are printed on startup.
• 🍎 iOS PWA shell — injects apple-mobile-web-app-capable, viewport-fit=cover, apple-touch-icon, programmatically generated PNG icons, and an enhanced manifest.webmanifest. After "Add to Home Screen" in Safari it opens fullscreen like a native app with its own icon.
• 👆 Touch adaptation — mobile CSS: inputs ≥16px to prevent iOS focus zoom, touch-action: manipulation to kill double-tap delay, notch / home-indicator safe-area insets, raising the composer above the on-screen keyboard (visualViewport tracking), and larger tap targets for message actions.
• 🔳 /mobile QR page — open http://127.0.0.1:3080/mobile on the desktop to get a big QR code plus step-by-step instructions; the phone camera opens the LAN URL in one scan.

⚠️ Security warning (read first)

Enabling this plugin exposes the full Harness — including its code-execution tools — to every device on your LAN. That is the price of "usable from a phone". Please:

• only keep it enabled on a network you trust (e.g. your home Wi-Fi);
• on public/untrusted networks, comment out the mobile row in cordis.patch.yml and restart;
• optionally restrict access to specific phone IPs with the allow config (see below).

🔧 Harness source patches (by need — no dsh-webchatlike dependency)

dsh-mobile itself does NOT depend on dsh-webchatlike — a stock harness without webchatlike works fine. Patches are applied as needed:

Patch 1: Secure-context UUID (required)

cd /path/to/deepseek-harness
pnpm run build:lib:client   # the running GUI hot-swaps client bundles; no restart needed

All patches are backed up in harness-patches/ for re-application after upstream updates.

Patch 2: webchatlike folding fallback (optional, only with dsh-webchatlike)

packages/client/ui-workspace/src/client/tree.ts, WorkspaceBrowser.tsx, index.ts — also backed up in harness-patches/.

Install from GitHub

Repository: github.com/cindyguyuehu123/dsh-mobile (built lib/ ships with the repo — no build step needed)

Option 1 — official plugin command (clones and installs dependencies automatically):

dsh plugin --profile web add https://github.com/cindyguyuehu123/dsh-mobile.git

Option 2 — manual registration (same as dsh-webchatlike):

# 1. Clone and install dependencies
git clone https://github.com/cindyguyuehu123/dsh-mobile.git
cd dsh-mobile && pnpm install

# 2. Add to ~/.dsh/profiles/web/package.json dependencies
#    "dsh-mobile": "link:/absolute/path/dsh-mobile"
cd ~/.dsh/profiles/web && pnpm install

# 3. Insert into ~/.dsh/profiles/web/cordis.patch.yml
# - insert:
#     - id: mobile
#       name: 'dsh-mobile'

Install (manual, detailed)

1. Build

cd /path/to/dsh-mobile
pnpm install
pnpm run build

Outputs: lib/index.js (host half) and lib/client.js (browser half, zero runtime imports).

2. Register in the profile

Edit ~/.dsh/profiles/web/package.json and add a link dependency:

"dependencies": {
  "dsh-mobile": "link:/path/to/dsh-mobile"
}

Then:

cd ~/.dsh/profiles/web && pnpm install

Edit ~/.dsh/profiles/web/cordis.patch.yml, insert the loader row:

- insert:
    - id: mobile
      name: 'dsh-mobile'

3. Restart

cd /path/to/deepseek-harness
pnpm dsh web

The log prints:

dsh-mobile: 📱 phone / iPad access: http://192.168.x.x:3090
dsh-mobile: desktop QR page: http://127.0.0.1:3080/mobile

Usage

1. Phone/iPad on the same Wi-Fi as the Mac;
2. Scan the QR on the desktop /mobile page (or type the printed URL);
3. In Safari: Share → Add to Home Screen for a native-app-like icon.

Configuration

The plugin row accepts an optional config (all optional):

- insert:
    - id: mobile
      name: 'dsh-mobile'
      config:
        lanPort: 3090     # proxy port; walks +1 when busy (default 3090)
        allow: []         # optional client-IP allowlist, e.g. ['192.168.1.20']; empty = allow all

How it works (no harness source changes needed for the plugin itself)

• The upstream WebServer's /api routes and WebSocket upgrades all pass isTrustedApiRequest: loopback Host passes, Origin (when present) must be same-origin. The proxy rewrites Host to 127.0.0.1:<loopback port> and same-origin Origin accordingly, so phone traffic looks exactly like local traffic to the core server — no harness source modification, and the blocked --host 0.0.0.0 is never touched.
• PWA parts use the public webServer.tapIndex() and route-registration extension points.
• The browser half rides the standard dsh.client channel (/plugins/dsh-mobile/client.js), same loading path as the shipped ui-* plugins.

Development

pnpm run build        # build lib/ via tsdown
pnpm run typecheck    # tsc --noEmit

Client-side changes hot-swap into a running GUI (bundle polling); host-side changes need a dsh web restart.

Known limitations

• LAN-only (or your own tunnel): the phone cannot reach the Mac over cellular.
• macOS may ask once to allow Node.js to accept incoming connections — allow it.
• Real-device keyboard/safe-area behavior is covered for mainstream iOS, but minor per-version differences may remain.
