I need to fix the SQL query - the error shows I tried to compute AVG on a VARCHAR column. Let me first inspect the columns to see their actual types, then write a corrected query that only computes statistics on truly numeric columns. ```json { "action": "tool_call", "reasoning": "The previous query failed because it tried to compute AVG/MEDIAN on VARCHAR columns. I need to inspect the columns to identify which ones are actually numeric (DOUBLE, BIGINT, DECIMAL, etc.) versus text that might contain numbers. This will let me write a correct query that only aggregates the numeric-typed columns.", "tool": "inspect_columns", "args": { "table": "raw.epoch_ai_benchmarks" } } ```
