dsh-quick-workspace

Make the sidebar's Add workspace button work when you are driving the DeepSeek Harness web UI from somewhere other than the host machine.

What was wrong

The stock flow opens an OS folder chooser on the host. dsh-host-directory-picker-auto resolves the native backend whenever the bind host is 127.0.0.1 on macOS, and that backend is a renderless osascript "choose folder with prompt …" call: it puts a Finder dialog on the host's screen and renders nothing in the browser.

So from a remote browser (Tailscale, LAN, a phone) the button looks completely dead, and it gets worse than dead — while the hidden dialog is open, WorkspacePickFlow holds directoryBusy, and shortcutControls.add is a no-op whenever that flag is set. Every later click is then silently ignored, with no error and nothing on screen.

What this plugin does

It occupies both directory-flow holes — the sidebar header button and the composer's Choose workspace — with a name dialog:

1. you type a name,
2. the dialog shows the exact path it is about to create,
3. DSH makes the folder and registers it as a workspace, then opens it.

New folders land beside the deployment's default workspace, which on this machine is ~/Documents/deepseek-harness/ for a workspace at ~/Documents/deepseek-harness/default-workspace.

It registers at priority: -100, which is the documented way to shadow a single-kind slot occupant: SlotCore.register sorts entries by ascending priority and the lowest renders, so this takes the seat instead of throwing already has a registration against the native/browse picker.

Install

dsh plugin --profile web add file:/path/to/plugins/dsh-quick-workspace

Then restart dsh web so the host half re-imports (see below).

Two things that bite when editing this

• lib/index.js needs a dsh web restart. The client half hot-reloads; the host half does not. After editing lib/index.js, rm -rf ~/.dsh/profiles/web/node_modules/dsh-quick-workspace and re-add, or restart the server.
• process.cwd() is /. dsh web runs as a launchd KeepAlive agent, so the working directory is the filesystem root, and mkdir("/<name>") fails with a bare EACCES that tells the user nothing. The parent comes from workspaceRegistry instead, and the root is refused outright with quick-workspace/no-parent.

Wire shapes worth remembering

• ctx.connection.rpc.call("/api", "ns/method", payload) resolves to the {ok, value | error} envelope. Reading .path straight off it yields undefined without throwing — always unwrap.
• The Gateway derives its argument descriptor from the Host method's signature. A parameterless describe() must be sent {args: {}}; {args: {request: {}}} is rejected with gateway/arguments-invalid.

Uninstall

dsh plugin --profile web remove dsh-quick-workspace (or disable it on the Plugins page), then restart dsh web. The stock folder picker comes back.
