Truncate Shows Its Work

Schema Recognition

The AI first scans your local database structure to understand available tables and types.
Relation Mapping

It identifies foreign keys and joins automatically, no manual tagging required.
Safety Checks

Before writing SQL, it verifies the query against safety rails (e.g., no DROP or DELETE).
