I have already obtained the column metadata for the beer_ratings table from step-0, which shows all 19 columns with their data types and semantic roles. Let me now get the complete column information for all tables in the dataset to provide a comprehensive answer. ```json { "action": "tool_call", "reasoning": "I have beer_ratings columns from step-0. The evidence also shows partial column lists from meta.columns queries (steps 1-4), but these are truncated at 50 rows and don't cover all tables. I need to query the complete column catalog to list all columns across all 13 tables with their types and meanings.", "tool": "query_sql", "args": { "sql": "SELECT table_name, column_name, phys_type, semantic_role, rough_kind FROM meta.columns ORDER BY table_name, column_name", "purpose": "Get complete list of all columns across all tables with their data types and semantic meanings", "source": "raw" } } ```
