I need to provide a comprehensive list of all columns across all tables in the dataset, with their data types and meanings. I already have column metadata from the inspect_columns calls, but those only showed 50 rows (a bounded subset). Let me query the complete column metadata from the meta.columns table to get all columns across all tables. ```json { "action": "tool_call", "reasoning": "The inspect_columns results only showed 50 rows out of what appears to be many more columns across 13 tables. I need to query meta.columns to get the complete list of all columns with their types and semantic roles.", "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 roles" } } ```
