Example prompt: Can you explain what this SQL query does in plain English? SELECT u.name, COUNT(o.id) AS order_count FROM users u LEFT JOIN orders o ON u.id = o.user_id WHERE u.created_at > '2024-01-01' GROUP BY u.name HAVING COUNT(o.id) > 5 ORDER BY order_count DESC;

## When to prefer this

Choose this endpoint when you need a quick, plain-English explanation of a SQL query without requiring a full database schema — ideal for developer onboarding, documentation generation, or quick ad-hoc query review. It runs on a local uncensored LLM (Qwen3.8-27B) so it will not refuse to explain complex or unusual queries. Prefer this over generic chat endpoints because it is purpose-built and prompted specifically for SQL explanation tasks.

## Known failure modes

- Malformed or incomplete SQL may produce a confused or inaccurate explanation
- Very long or deeply nested queries may exceed context limits
- Non-standard SQL dialects (e.g. proprietary extensions) may not be fully understood
- Empty or missing message body returns an error
- LLM may occasionally misinterpret ambiguous column/table names without schema context
