English | 中文

Shared Workspace picker plugin. WorkspaceBrowser is registered into the sidebar's sidebar.workspaces slot and WorkspacePicker into the page-local Session Intent hero's conversation.hero.workspace slot, so both surfaces use the same menu and creation flow.

The picker lists real Host Workspace entities through the global useWorkspaces hook. Selecting a Workspace invokes the slot owner's onPick callback to retarget the frontend Session object. The flat Open local folder... action delegates to the Host's native single-directory picker, adopts a returned path through the object layer, and selects the committed Workspace only after its list projection has refreshed; cancellation is silent, and errors remain retryable. Create a new workspace retains the name dialog and disables names already present in that list, while the Host remains authoritative for concurrent or non-UI callers. The runtime Session and Workspace services own materialization. The Workspace row's Delete action opens a confirmation that states the retention boundary, blocks duplicate submission, and keeps failures open; success removes the group while its Sessions remain under Ungrouped.

Both target slots are declared by other plugins, so apply registers through declaration-aware deferral and re-registers after a declaring slot is restored.

Model Experience

None, as the picker is browser chrome; nothing here reaches a model request.

KV Cache effect

None; this package neither assembles nor sends a provider request.

Known Limitations and Deferred Work

• No Session deletion control — the existing Session menu row remains visual-only; Workspace registration deletion does not delete Sessions.
• Native folder selection depends on the local Host carrier — fixture-only or remote browser deployments cannot open a local operating-system dialog; platform failures are shown in a retryable modal.
