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 metadata to get the complete picture. ```json { "action": "tool_call", "reasoning": "The inspect_columns results only show 50 columns out of 2,061,290 total rows across 51 tables. I need to query the meta.columns catalog to get all columns with their types and semantic roles, which will give me the complete list of columns, their data types, and what they represent.", "tool": "query_sql", "sql": "SELECT table_name, column_name, phys_type AS data_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" } ```
