Operation-aware node configuration guidance. Use when configuring nodes, understanding property dependencies, determining required fields, choosing between get_node detail levels, or learning common configuration patterns by node type — including the native nodes that replace Code (Summarize, Aggregate, Split Out, Merge, Compare Datasets, Remove Duplicates, Sort, Limit, Date & Time, HTTP Request pagination, Crypto). Always use this skill when setting up node parameters — it explains which fields are required for each operation, how displayOptions control field visibility, and when to use patchNodeField for surgical edits vs full node updates.
