Is there an Api to get current organization from context programmatically, similar to getProject() and getStack()? I need this for tagging and to create a StackReference()

Unfortunately I am not aware of a way to do this current. Though I can’t think of any reason why we wouldn’t support that. Please feel free to open a new issue at https://github.com/pulumi/pulumi/issues/new, and we can look into adding that in a future SDK release.
