I need to first check the exact column names in the table before querying it. ```json { "action": "tool_call", "reasoning": "The previous query failed because I used an incorrect column name. I need to inspect the actual columns in the raw.ai_supercomputers table to see what's available, then I can write a correct SELECT query to show a representative sample.", "tool": "inspect_columns", "args": { "table": "ai_supercomputers" } } ```
