The gettemporaryattachments command will return a list of attachment points by object UUID of the worn temporary objects such as objects attached via the LSL function llAttachToAvatarTemp.

llInstantMessage(CORRADE,
    wasKeyValueEncode(
        [
            "command", "gettemporaryattachments",
            "group", wasURLEscape(GROUP),
            "password", wasURLEscape(PASSWORD),
            "callback", wasURLEscape(URL)
        ]
    )
);

The command returns a CSV list of attachment points, by object UUID of all worn temporary objects.

• Temporary attachments do not exist in the inventory store such that only the attachment point name and the object UUID is returned by this command.
