I need to identify the categorical columns across all tables and count their distinct values. Let me start by inspecting the columns of each table to understand their types and semantic roles. ```json { "action": "tool_call", "reasoning": "I need to see the column metadata for all tables to identify which columns are categorical. I'll start with the largest table, b2b_sales_funnel_pipeline, to understand its structure.", "tool": "inspect_columns", "args": { "table": "b2b_sales_funnel_pipeline" } } ```
