I'll systematically check for data quality issues across this boxing dataset. Let me start by understanding the structure and then examine each table for problems. ```json { "action": "tool_call", "reasoning": "First, I need to understand the overall structure and get a sense of what columns exist across these tables. I'll read the topology section to understand the dataset structure, then inspect the main tables.", "tool": "read_insight", "args": { "section": "topology" } } ```
