I need to identify columns with missing values and calculate the percentage of missing data for each column in the dataset. Let me start by getting detailed metadata for all columns in the table to see null counts. ```json { "action": "tool_call", "reasoning": "I need to inspect all columns in the raw.callyeah_analytics_2026_07_23 table to get null counts and calculate missing percentages. The inspect_columns tool will give me null_count for each column, which I can use along with the total row count (216) to calculate percentages.", "tool": "inspect_columns", "args": { "table": "callyeah_analytics_2026_07_23" } } ```
