DescriptionRunAgentInput multimodal content permits source: {type: "url", value: <string>}. The value is a bare string in the protocol model with no scheme or host validation. The aws-strands integration fetches it with urllib.request.urlopen() while building the model input history; urllib supports file:///ftp:// and follows redirects.
