dsh-quick-workspace

dsh-quick-workspace

The core's "ungrouped" session group has no workspaceId, and its + button is guarded by group.workspaceId !== undefined (packages/client/ui-workspace/src/client/WorkspaceBrowser.tsx), so clicking it does nothing — a session must belong to a workspace by design. This plugin does not touch the core; it adds a side door: the DSH Launcher POSTs an absolute path, the workspace is created, and a page refresh lets you pick it and start chatting.

Install

dsh plugin --profile web add dsh-quick-workspace

Restart dsh afterwards. As part of DSH CyberWorkStation the plugin is registered by setup.cmd from the repository checkout instead.

The DSH Launcher's dashboard is its only user interface; without the launcher it only exposes the routes below.

Routes

Route	What it does
POST /dsh-quick-workspace/create	{ "path": "D:/projects/my-project", "title": "optional" } — creates the directory if it does not exist, then registers a workspace for it
GET /dsh-quick-workspace/list	the registered workspaces (id, path, title)

What it will do to your disk

create runs mkdirSync(path, { recursive: true }) on any absolute path this process can write, with no allow-list, and then registers it. That is the feature — it is how you make a workspace for a folder that does not exist yet — but it is worth knowing before you point it somewhere. On Windows a UNC path (\\host\share\x) makes the dsh process authenticate outbound to that share.

Fence

Both routes carry the suite's loopback + same-origin fence: a foreign Host header is refused on every method (DNS rebinding), a cross-site or same-site fetch is refused, the Origin must match the whole authority, a POST must be application/json, the body is counted in bytes and capped at 64 KB (a refused body is drained, not reset), and an array body is not an object.

Without that fence any web page could have made this route create directories, which is what a review round found: a cross-site POST created a directory on the running instance before the fence landed.
