```json { "action": "tool_call", "reasoning": "The dataset card shows raw.Iris has 150 rows and 10 columns, but I need to verify if there's any temporal coverage. The card lists _ingestion_timestamp as a column, but that's metadata about when data was loaded, not the dataset's inherent time period. I should check if there are any actual date/time columns that represent the data's temporal scope. I'll inspect the columns to see their types and check for any temporal dimensions beyond the ingestion metadata.", "tool": "inspect_columns", "args": { "table": "Iris" } } ```
