I'll systematically check for data quality issues across the dataset. Let me start by examining the structure and then look for specific problems. ```json { "action": "tool_call", "reasoning": "First, I need to understand the column structure across all tables to identify what types of quality issues to look for. I'll start with the main cleandata table to see what columns exist and their types.", "tool": "inspect_columns", "args": { "table": "raw.cleandata" } } ```
