I need to get a complete list of all columns across all tables with their data types and semantic meanings. The evidence so far shows only 50 rows from `inspect_columns`, which is truncated. I'll query the metadata to get the full column catalog. ```json { "action": "tool_call", "reasoning": "The inspect_columns results are truncated at 50 rows. To get a complete list of all columns with their types and meanings across all 51 tables, I'll query the meta.columns table which contains the full column catalog with phys_type (data type) and semantic_role (meaning).", "tool": "query_sql", "args": { "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 with their data types and semantic roles across all tables" } } ```
