dsh-coding-remote-kit

---

Community plugin. Not affiliated with, and not endorsed by, DeepSeek. Product intent is closer to Orca Mobile Companion than to a second copy of the desktop IDE.

Read AGENTS.md before changing this repo: do not restart production dsh-web yourself. Prepare the tarball; the operator restarts.

Names

Developed first as GitHub dsh-mobile-remote. The npm name dsh-mobile-remote is a different project (a WeChat remote-control plugin). This plugin publishes as dsh-coding-remote-kit.

Do not dsh plugin add dsh-mobile-remote — that installs the unrelated WeChat plugin.

Features

• Bilingual UI — Chinese and English for desktop Settings and the phone companion (?lang= / in-app switch; defaults from navigator.language).
• Pair once — desktop shows a QR code or 8-digit PIN; the phone pins the desktop X25519 public key and holds a deviceToken (server stores SHA-256 only).
• Dual plane — management routes stay on loopback dsh web; the mobile data plane is a dedicated port (default 6879) with an RPC allowlist.
• E2EE after handshake — tweetnacl secretbox on /m/ws; unauthenticated sockets never see session content.
• Narrow writes — observe sessions, answer approvals/questions, short replies; heavy editing stays on the desktop.
• Private-network first — LAN / Tailscale preferred. Optional Cloudflare Quick Tunnel exposes only the data plane, never port 3080. Optional self-hosted rendezvous Worker: desktop and phone both outbound; business frames stay E2EE.
• Standard plugin shape — one Cordis server plugin + classic-script Settings page. dsh plugin --profile web add a file tarball, never a link: working tree.

Problems this plugin solves

You searched / saw	What was actually broken	What this plugin does
“Orca-style phone companion for DSH”	Official DSH has no first-class paired mobile app	Semantic companion: pair + E2EE + allowlisted RPC
dsh-pocket / dsh-web-remote on a phone	Full dsh web surface on LAN/public	Dual plane; unknown RPC methods are forbidden
Phone on cellular, desktop on LAN	Raw LAN HTTP page can be MITM’d	Prefer Tailscale; optional Quick Tunnel (TLS at the edge, localhost origin)
Plugin import failed and port 3080 died	DSH fail-fasts the whole plugin tree	Sandbox gate + packed tarball copied outside the repo; no link:

Quick start

dsh plugin --profile web add dsh-coding-remote-kit@0.3.0

Then the operator restarts the existing dsh web process in their own window. Open Settings → Mobile Remote, create a pairing offer, scan the QR (or type the PIN) on the phone.

From a source checkout (development):

pnpm test:sandbox
pnpm pack
mkdir -p "$HOME/.dsh/packages"
cp dsh-coding-remote-kit-0.3.0.tgz "$HOME/.dsh/packages/"
dsh plugin --profile web add "$HOME/.dsh/packages/dsh-coding-remote-kit-0.3.0.tgz"

Do not dsh plugin add ./ from this working tree. pnpm 11 treats some file: tarball paths as link: source, and a bad entry import takes down the whole GUI.

Install

Requires DeepSeek Harness 0.1.0-rc.7 (pinned) and Node.js 22.19+. Full steps, pairing, and tunnel notes: INSTALL.md.

Development:

pnpm install && pnpm build && pnpm test   # inside the Docker sandbox, not on a live GUI host
pnpm test:sandbox                         # Dockerfile targets check / isolated-install / verify

Build outputs:

• lib/server/index.js — Cordis entry (name / inject / Config / apply)
• lib/client.js — Settings classic-script
• lib/mobile/ — phone page served at /m

How it works

Settings (loopback)          Phone browser
        │                            │
        │  QR / PIN  ────────────────┤
        ▼                            ▼
 /api/mobile-remote/*          GET /m  +  WS /m/ws
   (dsh web, :3080)            (data plane, :6879, E2EE)

Management stays behind the host Web loopback fence. The data plane is a separate node:http + ws server. Pairing may rebind it from 127.0.0.1 to 0.0.0.0 so LAN clients can connect; an active Quick Tunnel advertises its HTTPS origin instead of widening.

Settings page

Open Settings → Mobile Remote:

• status (bind, port, listening, active devices, tunnel, rendezvous)
• LAN / Quick Tunnel / rendezvous channels
• create offer → QR + 8-digit PIN
• device list and revoke
• optional official cloudflared install (never runs at plugin apply())

Mobile RPC

Allowlisted methods (everything else is forbidden):

status.get · session.list · session.history · session.subscribe · session.unsubscribe · host.subscribe · session.prompt · session.cancel · session.create · respond

Pushes include session events plus approval.requested / question.requested (with rpcId for respond). Wire format: docs/03-protocol.md.

Public tunnel

Default off. When started from Settings, cloudflared Quick Tunnel points only at 127.0.0.1:<data-plane-port>. /m becomes reachable on a https://<random>.trycloudflare.com URL; pairing still needs the fragment token (or PIN) and E2EE. The child process is killed on plugin unload / Stop.

Never tunnel port 3080 / dsh web. A self-hosted rendezvous Worker (desktop and phone both outbound, business frames still E2EE) is optional; see docs/05-cloud-relay.md. It needs a Cloudflare Workers Paid plan and is not a public relay operated by this project.

Security

Invariants (full model: docs/04-threat-model.md):

1. Unauthenticated connections handle handshake only.
2. deviceToken is stored as SHA-256; keys and registry files are 0600.
3. RPC allowlist, default deny; writes are audited to deviceId.
4. Management plane is loopback + Host + CSRF.
5. The plugin does not weaken dsh web /api and does not take over api-proxy providers.

Honest v0 boundary: the first HTTP download of /m on a raw LAN can be MITM’d. Prefer an overlay VPN.

Prohibitions:

• Do not share another person's credentials.
• Do not monitor accounts you are not authorized to access.
• Do not bind the data-plane port on 0.0.0.0 to the public Internet (Quick Tunnel is an explicit, user-started exception).
• Do not imply DeepSeek official endorsement.

Examples in docs use example.com, 127.0.0.1, and YOUR_TOKEN only.
