I need to get a comprehensive list of all columns across all tables with their data types and meanings. The evidence so far shows only the first 50 columns. Let me query the full column catalog to get complete information. ```json { "action": "tool_call", "reasoning": "The inspect_columns results show only 50 columns out of 1,533,257 rows in raw.columns_catalog. I need to query the full catalog to get all columns with their types and semantic roles. I'll use the analytics.column_overview metadata view which provides column-level details including data types and semantic roles.", "tool": "query_sql", "args": { "sql": "SELECT table_name, column_name, phys_type AS data_type, semantic_role, rough_kind FROM analytics.column_overview ORDER BY table_name, column_name", "purpose": "Get complete list of all columns with their data types and semantic meanings" } } ```
