```json { "action": "tool_call", "reasoning": "The dataset card shows raw.boxing_matches has 30 columns. To classify them properly (identifiers, categorical dimensions, numeric metrics, dates/times), I need detailed metadata including semantic_role, rough_kind, and phys_type for all columns. The card lists column names and types but doesn't show semantic roles. I'll use inspect_columns without specifying columns to get the first 30 (which should cover all of them since there are exactly 30).", "tool": "inspect_columns", "args": { "table": "boxing_matches" } } ```
