I need to provide a comprehensive list of all columns across all tables in this dataset, including their data types and meanings. Let me start by inspecting each table systematically. ```json { "action": "tool_call", "reasoning": "Starting with the largest table, b2b_sales_funnel_pipeline, to get its columns, types, and semantic meanings. This will form the foundation of the answer.", "tool": "inspect_columns", "args": { "table": "b2b_sales_funnel_pipeline" } } ```
