I need to classify all columns across the 5 tables in this dataset. Let me start by inspecting each table's columns to get their types and semantic roles. ```json { "action": "tool_call", "reasoning": "Starting with the largest table b2b_sales_funnel_pipeline to understand its column structure, types, and semantic roles. This will help classify identifiers, dimensions, metrics, and temporal columns.", "tool": "inspect_columns", "args": { "table": "b2b_sales_funnel_pipeline" } } ```
