dsh-remote

Remote-work assistant for DeepSeek Harness (DSH).

Manage several SSH machines, then pick a remote workspace (or a local one) and let the agent operate right there without leaving the harness — listing files, reading code, running builds & commands over the remote host, and keeping that remote directory mirrored into a real local workspace object.

The harness Web UI intentionally binds 127.0.0.1 (the CLI rejects --host 0.0.0.0 for safety). This plugin goes the other way: you connect out to the machines you maintain, pick a workspace, and work in it through the normal DSH workspace + agent fs flows — no changes to dsh-workspace or the harness core.

Screen previews

Settings → 远程工作区 — a multi-machine SSH registry (add / edit / delete / set-current, password stored locally):

The native "Add workspace" / "Select workspace" flow — a centered modal, two tabs, opens on 本机 (local); switch to 远程 (remote):

• 远程 — a machine <select>, a path field that auto-prefills / and live-completes directories (picking one immediately reveals its next level, OS/VSCode-style), plus a 浏览… floating browser that fills the field without committing — you review, edit, then 设为远程工作区.

Real capture (host scrubbed to a placeholder):

Features

• Multi-machine SSH — save any number of hosts (host/port/user + private key or password). Passwords are stored locally and never shown back in the UI. Switch with one click in Settings. Per-machine passphrase / host-key mode / SSH agent / keyboard-interactive (OTP) / proxy jump (bastion) and an optional OS-keychain password (加密保存密码 — macOS Keychain / Windows DPAPI / Linux secret-tool).
• ~/.ssh/config import — the Settings page lists your Host aliases; one click fills the form (path reference only, the plugin never reads key material).
• Two-tab workspace picker (fills the native "Add workspace" flow):
  • 本机 / Local — opens the native OS folder chooser over the host (macOS osascript / Linux zenity→kdialog / Windows FolderBrowserDialog), or lets you type a local path → adopted directly as a normal DSH local workspace.
  • 远程 / Remote — the picker is a centered modal. Pick a machine → the path field is pre-filled with / and live autocompletes directories; selecting a directory immediately lists its next level. A 浏览… floating browser (shows size + mtime, dirs first, follows symlinks) fills the field without committing. 最近 workspaces quick-pick, ~ 主目录 shortcut and 新建目录 are one click away. On confirm it creates a real local mirror under $DSH_HOME/remote-workspaces/<host>-<user>-<port>/<base> that passes fs.realpath → the harness adopts it as a real workspace while dsh-remote keeps it synced over SFTP.
• Bidirectional SFTP sync, conflict-aware — rw_sync (remote → mirror) and rw_push (mirror → remote) are three-way (remote vs local vs last-synced snapshot): files changed on both sides are reported as conflicts and never silently overwritten (force=true overrides). Both support dry-run, background tasks, and honor gitignore-style ignore rules (.dsh-remote-ignore under remote-workspaces, defaults cover .git/node_modules/target/dist/build/…).
• Model tools — 20 tools, all Windows/POSIX portable via SFTP: rw_info, rw_connect (with save), rw_pick_workspace, rw_list_dir (size+mtime), rw_stat, rw_read_file (encoding-aware: utf-8/gbk), rw_write_file, rw_edit (literal replace + mtime optimistic lock), rw_append, rw_mkdir, rw_remove (recursive, bounded), rw_move, rw_exec (pty/env), rw_search (SFTP tree walk — works on Windows too, honors ignore rules, context lines), rw_download/rw_upload (streaming fastGet/fastPut + size caps), rw_forward (SSH tunnels), rw_sync, rw_push, rw_disconnect.
• Port forwarding panel — create/start/stop/remove local (127.0.0.1:port → remote) and reverse (remote → local) tunnels in the Settings page or via rw_forward; definitions persist, auto-restart on reconnect when enabled, all tunnels stop on disconnect.
• Sidebar remote editing — the better-sidebar remote file tab is now editable: click 编辑 → edit → 保存到远程 with an mtime optimistic lock (409 + "重新读取" on concurrent change). The explorer rows show file sizes and have a right-click menu (下载到本地镜像 / 重命名 / 删除 / 新建目录).
• Command audit log — every rw_exec/write/remove/move/forward is appended to $DSH_HOME/remote-workspaces/audit.log (time · user@host · op · exit code · command); the Settings page shows the last 30.
• Async long tasks — rw_sync/rw_push with async: true return a taskId; progress/result/cancel via /dsh-remote/task (single-flight queue).
• Connection health — a 「测试连接」 button validates host/user/key/password (with per-category error hints: auth / network / host key / timeout) before you save a machine; latency is cached on the machine record.
• The active user@host:/path is injected into every system prompt (plus active forwards).
• No official dsh-workspace core is modified — everything is delivered as a normal plugin (directory-flow holes filled by the client half at priority -100).
• Cross-platform remotes — all file access is SFTP-protocol-level (no shell dependency), so Linux/macOS/Windows remotes all work for listing, reading, writing, searching and syncing.
• Host-key verification (TOFU) — every SSH connect verifies the host key (hostKeyMode: accept-new): first connect records it, a later CHANGE is rejected as a possible man-in-the-middle. verify also refuses hosts never seen before; off disables it. Stored at $DSH_HOME/remote-workspaces/known_hosts.json; reset with /remote forget-key.
• Data lives under the harness home — machines + mirrors follow $DSH_HOME; pre-0.6 data under ~/.dsh/remote-workspaces is migrated automatically on first run.

Install

dsh plugin add dsh-remote            # add the bundle

One command installs everything: since v0.7.2 the sidebar (dsh-better-sidebar) is a hard dependency and is mounted automatically — the 🌐 remote-file explorer and remote file viewer show up in the sidebar with no extra step. If you already have the sidebar installed on its own, the embedded copy backs off (no double mount) — regardless of whether the standalone bundle is listed before or after dsh-remote in dsh.profile.bundles (order-independent guard since 0.8.7; earlier versions crashed boot with duplicate prefix route "/sidebar/api" when the standalone bundle came after dsh-remote).

Upgrading from ≤0.8.6 with a standalone sidebar? You may keep the standalone dsh-better-sidebar bundle (any order) — 0.8.7+ no longer crashes. Or remove it from bundles and let dsh-remote mount the embedded copy (version ^0.14.0).

Requires the profile's pnpm linker to be hoisted (the DSH profile default, nodeLinker: hoisted in pnpm-workspace.yaml). The loader resolves plugin packages from the profile root, so the sidebar must be reachable in the top-level node_modules. If your pnpm-workspace.yaml was rewritten without nodeLinker: hoisted, add it back (nodeLinker: hoisted) and run pnpm install once — otherwise the embedded sidebar row fails with Cannot find package 'dsh-better-sidebar'.

(or npm install dsh-remote + add - id: dsh-remote / name: dsh-remote in cordis.patch.yml).

Quick start

1. Add a machine — Settings → 远程工作区 → add host/port/user + key or password → (optional) set it current.
2. Open a workspace — click Add workspace in the sidebar / conversation:
   • 本机 → system folder chooser (or type a local path) → local workspace. On hosts without a usable OS dialog (DSH Desktop's browse backend, headless SSH hosts without zenity/kdialog) the in-app directory browser pops up instead — breadcrumbs, Windows drive switch, new-folder, pick-and-fill.
   • 远程 → choose the machine → browse to a remote directory (or type /path) → "设为远程工作区" ⇒ a local mirror workspace is created and adopted.
3. Work with the agent — treat it like any workspace:
   • rw_list_dir(path?)/rw_read_file — inspect remote files
   • rw_write_file(path, content) / rw_edit(path, old, new) — create / patch a remote file directly
   • rw_stat(path) / rw_mkdir(path) / rw_remove(path, recursive?) / rw_move(path, dest) — manage remote paths
   • rw_search(pattern, path?) — grep remote files (SFTP walk, Windows OK)
   • rw_exec(command, cwd?, pty?) — run remote shell commands (defaults to the workspace dir)
   • rw_forward(listenPort, targetHost?, targetPort?) — open an SSH tunnel
   • rw_sync(dryRun?/force?/async?) / rw_push(dryRun?/force?/async?) — conflict-aware mirror pull/push

CLI defaults (optional)

Provide a default machine in cordis.patch.yml:

# Example only — use values for your own machine.
- id: dsh-remote
  name: dsh-remote
  config:
    host: 203.0.113.10   # or your real host / hostname
    port: 22
    username: dev
    privateKeyPath: ~/.ssh/id_rsa
    # or password: '…'
    workspace: ~/project

If host is empty the plugin starts disconnected and you configure machines in the UI.

CLI quick reference

Installing and driving DSH may live in different shells, so both the dsh binary and the npx form are shown. Always tell DSH which profile to use with --profile <name> (usually web).

# install the bundle into a profile (npm is pulled by pnpm; recommended)
dsh plugin --profile web add dsh-remote
# same but when `dsh` is not on PATH (e.g. Windows PowerShell inside a repo)
npx --yes @deepseek-ai/dsh plugin --profile web add dsh-remote

# confirm it is installed wire
dsh plugin --profile web list
npx --yes @deepseek-ai/dsh plugin --profile web list

# start the web surface (reload profile; the plugin activates on boot)
dsh --profile web
npx --yes @deepseek-ai/dsh --profile web   # http://127.0.0.1:3080

# use a local checkout instead of the npm version (dev iteration)
npx --yes @deepseek-ai/dsh plugin --profile web add /path/to/dsh-remote
npx --yes @deepseek-ai/dsh plugin --profile web remove dsh-remote   # back to release

After a successful start, Settings → 远程工作区 appears and the "Add workspace" flow gains the 本机 / 远程 tabs (screenshots above).

Development (sandbox, not product)

Iterate in the sandbox, never by hand-editing a product profile — the product profile is re-managed by the plugin manager and reverts hand-deployed files on reinstall. Use the helper script:

scripts/dev-run.sh --restart   # start / restart the isolated sandbox
scripts/dev-run.sh --stop      # stop it
scripts/dev-run.sh --status    # is it running?

• Runs its own DSH instance (dev-harness/harness inside this repo) with the plugin copied in from lib/ — it boots through the same bin.js web --patch path as the desktop app, so the sandbox reproduces the product boot behavior.
• The sandbox web UI serves on http://127.0.0.1:50599 and the plugin routes are live immediately (e.g. GET /dsh-remote/machines).
• Host-half changes (lib/index.js) need a sandbox restart (--restart); client-half changes (lib/client.js) need a page refresh.
• Node ESM resolves dependencies from the importing file's real path, so the script copies lib/ (hardlink copy, cp -al) into the sandbox profile instead of symlinking — a symlink breaks @deepseek-ai/* resolution.
• Run scripts/check.mjs (static framework-constraint gate: command-name regex, …) before every commit; scripts/boot-smoke.sh boots an isolated instance to prove the plugin still starts.
• Full rules live in scripts/dev-standards.md (command names, cordis service access via ctx.get() only, optional framework services may never register, verify third-party callback contracts against the real runtime, …).

Deploying to a product profile is a separate, explicit action (./sync.sh) and should be done only when you intend to release.

Configuration

FAQ / troubleshooting

Host key 变了 / 提示可能中间人 — 主机重装过或密钥更换过：/remote-forget-key（或设置页 → 机器 → 重新信任），下次连接重新记录。

连接报"认证失败" — 检查用户名/密码/私钥路径；私钥加密了要填 Passphrase；公司机器要求 OTP/动态码时勾选 keyboard-interactive。

连不上内网机器 — 走跳板机：机器表单里填「跳板机」主机（也可以先把它本身配成一台机器）。主机不可达类错误会给出分类提示。

rw_sync/rw_push 报冲突 — 远端和本地都改过同一个文件时会跳过并列出冲突（绝不静默覆盖）。处理：手动合并后重新同步，或用 force=true 以一边为准。

Windows 远程 — 列表/读写/搜索/同步全部走 SFTP 协议，不依赖 POSIX shell；中文文件用 encoding=gbk 读。

镜像里没有某个目录 — 默认 ignore 规则（.git、node_modules、target 等）会跳过；在 $DSH_HOME/remote-workspaces/.dsh-remote-ignore 加 ! 之外的条目即可调整（gitignore 语法）。

侧边栏远程文件保存失败（409） — 远端文件在你打开后已被改动，重新读取后再编辑（mtime 乐观锁保护）。

密码怎么加密保存 — 机器表单勾选「加密保存密码」：macOS 用系统钥匙串（security），Windows 用 DPAPI，Linux 需要 secret-tool（libsecret）；后端不可用时自动回退明文。

Safety

Giving the plugin a machine's credentials lets the agent run shell commands as your user on that host. Only add machines you trust. Passwords are saved on the local machine file (or the OS keychain when enabled); treat it as sensitive (you may lock file ACLs). Every executed command is recorded in the audit log when auditLog is on — review it from the Settings page.
