I need to check for duplicate or near-duplicate rows in the ai_supercomputers dataset. Let me start by understanding the structure and then look for duplicates. ```json { "action": "tool_call", "reasoning": "First, I'll inspect the columns of the raw.ai_supercomputers table to understand what fields exist and which might serve as natural keys or identifiers for detecting duplicates.", "tool": "inspect_columns", "args": { "table": "ai_supercomputers" } } ```
