I need to first understand what columns are available in the quality_issues table, since my initial query failed. ```json { "action": "tool_call", "reasoning": "The query_sql call failed because 'issue_type' doesn't exist in raw.quality_issues. I need to inspect the actual column names in this table to understand how quality issues are structured.", "tool": "inspect_columns", "args": { "table": "quality_issues" } } ```
