I need to identify the main categorical columns and find their most common values with frequencies. Let me start by inspecting the columns to understand what we're working with. ```json { "action": "tool_call", "reasoning": "The dataset card shows many classifiers but doesn't list column ownership. I need to inspect the benchmarks table to see all columns and their types to identify the main categorical ones.", "tool": "inspect_columns", "args": { "table": "benchmarks" } } ```
