I need to check for duplicate and near-duplicate rows across the dataset's tables. Let me start by examining the table overview to understand the structure and identify which tables might have duplicates. ```json { "action": "tool_call", "reasoning": "First, I'll query the table overview to see row counts and understand the dataset structure. This will help me identify which tables to check for duplicates.", "tool": "query_sql", "args": { "sql": "SELECT table_name, row_count, column_count FROM analytics.table_overview ORDER BY row_count DESC", "purpose": "Get overview of all tables to plan duplicate detection strategy" } } ```
