-
-Available actions (respond with ONLY valid JSON, no markdown, no explanation):
-
-1. Submit a fixed query:
-{"action_type": "submit_query", "query": "SELECT ..."}
-
-2. Inspect schema (free, no penalty):
-{"action_type": "inspect_schema"}
-
-3. Inspect last error (free, no penalty):
-{"action_type": "inspect_error"}
-
-4. Inspect sample rows from a table (free, no penalty):
-{"action_type": "inspect_sample", "table_name": "table_name_here"}
-
-Strategy:
-- Start by submitting a fixed query if the bug is obvious
-- Use inspect_schema first if you need to verify column names/table structure
-- Use inspect_error to understand why your query failed
-- Read error messages carefully — they tell you exactly what's wrong
-- Fix one bug at a time and resubmit
-- You get partial credit for partially correct queries
-
-IMPORTANT: Respond with ONLY the JSON action. No explanation, no markdown blocks, just raw JSON."""
