I see the evidence contains repeated inspect_columns results showing the same 50 columns across multiple steps. Let me get the complete column list for all tables in the dataset. ```json { "action": "tool_call", "reasoning": "The evidence shows only the first 50 columns from inspect_columns calls. To provide a complete list of all columns with their types and meanings, I need to query the metadata catalog which contains all columns across all 43 tables. I'll use meta.columns which provides table_name, column_name, phys_type (data type), and semantic_role (what it means).", "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 across all tables with their data types and semantic meanings", "source": "raw" } } ```
