Operation-aware node configuration with progressive discovery and property dependency management. \n \n Start with get_node({detail: \"standard\"}) for 95% of configuration needs; escalate to full detail or search_properties mode only when standard doesn't provide required information \n Resource and operation determine which fields are required; use validation iteratively to discover conditional dependencies controlled by displayOptions rules \n Common patterns include resource/operation nodes
