I need to identify the main categorical columns and find their most common values with frequencies. Let me start by inspecting the tables to understand their structure. ```json { "action": "tool_call", "reasoning": "I need to see the columns in the main tables to identify categorical columns. Starting with b2b_sales_funnel_pipeline as it's the largest table with 8,800 rows.", "tool": "inspect_columns", "args": { "table": "b2b_sales_funnel_pipeline" } } ```
