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 evidence, but it's truncated (showing only 50 rows). Let me get the complete column list. ```json { "action": "tool_call", "reasoning": "The evidence shows truncated column metadata (50 rows). I need to query the complete meta.columns table to get all columns across all 13 tables 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 information" } } ```
