flymysql/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.

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.
• Two-tab workspace picker (fills the native "Add workspace" flow):
  • 本机 / Local — opens the native OS folder chooser over the host, or lets you type a local path → adopted directly as a normal DSH local workspace (local workspaces fully coexist).
  • 远程 / Remote — pick a machine, then browse its directories (or type a path) 🡺 on confirm it creates a real local mirror (~/.dsh/remote-workspaces/<host>/<base>-<hash>) that passes fs.realpath → the harness adopts it as a real workspace while dsh-remote keeps it synced over SFTP.
• Bidirectional SFTP sync — rw_sync (remote → mirror) and rw_push (mirror → remote) round-trip your local-mirror edits back to the machine.
• Model tools — rw_info, rw_connect, rw_pick_workspace, rw_list_dir, rw_read_file, rw_exec, rw_sync, rw_push.
• The active user@host:/path is injected into every system prompt so the agent knows its working root.
• 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).

Install

dsh plugin add dsh-remote            # add the bundle

(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.
   • 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_exec(command) — run remote shell commands
   • rw_sync / rw_push — pull/push the local mirror to and from the remote

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).

Configuration

Key	Type	Default	Meaning
host	string	''	default SSH host (else start disconnected)
port	int	22	default SSH port
username	string	''	default SSH user
password	string	''	default SSH password (non-empty overrides key)
privateKeyPath	string	''	private key path (~/.ssh/id_rsa when empty)
workspace	string	''	default remote workspace path
commandTimeoutMs	int	20000	per remote command timeout
connectTimeoutMs	int	15000	SSH connect timeout

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; treat it as sensitive (you may lock file ACLs).
