```json { "action": "tool_call", "reasoning": "The question asks for a classification of all columns in the dataset. The DATASET CARD shows raw.Dummy Data has 16 columns. I should use inspect_columns to get detailed metadata including semantic roles, types, and statistics for all columns, which will allow me to classify them as identifiers, categorical dimensions, numeric metrics, or dates/times. Since there are 16 columns and inspect_columns returns the first 30 by default when columns parameter is omitted, one call will cover all of them.", "tool": "inspect_columns", "args": { "table": "Dummy Data" } } ```
