+### Session Resumption Behavior
+
+By default, Goose automatically resumes workspace-specific sessions when your workspace restarts. Sessions are named `task-{workspace_name}`, ensuring each workspace maintains its own conversation history. If no session exists (first start), your task prompt will run normally. To disable this and always start fresh, set `continue = false`.

 ## Examples
 
 ### Run in the background and report tasks
