I'll systematically check for data quality issues across this dataset. Let me start by examining the column details to understand what we're working with. ```json { "action": "tool_call", "reasoning": "Need to see the full column metadata for raw.Dummy Data to understand data types, null counts, and value ranges before checking for quality issues", "tool": "inspect_columns", "args": { "table": "raw.Dummy Data" } } ```
