I need to provide a comprehensive list of all columns across all tables in this dataset, with their data types and meanings. The evidence so far shows inspect_columns results, but they're truncated at 50 rows and only cover a few tables. I need to query the metadata to get the complete picture. Let me query the meta.columns table to get all columns with their types and semantic roles, which will tell us what each column means. ```json { "action": "tool_call", "reasoning": "The inspect_columns results are truncated and only show a subset of tables. I need to query meta.columns to get the complete list of all columns across all 43 tables with their data types and semantic meanings.", "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 to explain what each column means" } } ```
