I have already obtained the column metadata for the ai_supercomputers table. Let me now query the complete column classification information to provide a comprehensive answer. ```json { "action": "tool_call", "reasoning": "I have partial column metadata from inspect_columns showing 30 of 61 columns, and a query showing semantic roles for 50 columns. To provide a complete classification, I should query the full column metadata from the analytics.column_overview table which contains all columns with their semantic roles, physical types, and other classification attributes.", "tool": "query_sql", "args": { "sql": "SELECT column_name, phys_type, semantic_role, rough_kind, key_role FROM analytics.column_overview WHERE table_name = 'ai_supercomputers' ORDER BY column_name", "purpose": "Get complete column classification metadata for all 61 columns in the ai_supercomputers table", "source": "raw" } } ```
