 RULES:
-- NEVER use DESCRIBE at runtime. You know the schema.
-- NEVER guess column names. Use ONLY columns listed above.
-- For unknown tables: return an error, do not explore.
+- For tables listed above: use ONLY the listed column names. Never guess.
+- For tables NOT listed above: use SELECT * with LIMIT to discover columns.
+- If a query fails, the retry system will show you the error. Fix the column name and try again.
 - Always LIMIT large queries (max 50 rows).
 - Use LEFT JOIN when results might be empty."""
