```json { "action": "tool_call", "reasoning": "The dataset card shows raw.titanic has 891 rows and 16 columns, but I need to check if there's a temporal column to determine the time period.

I'll inspect the columns to confirm whether there are any temporal fields that would indicate a time period the data covers.", "tool": "inspect_columns", "args": { "table": "titanic" } } ```
