"name": "queryDatabase",
"arguments": {
"projectId": "REPLACE_WITH_PROJECT_ID",
"databaseId": "REPLACE_WITH_DATABASE_ID",
"query": "SELECT 1 AS result"
}
} Result
The same data as the API operation, wrapped as {"untrusted_data": true, "source": "queryDatabase", "note": "...", "data": ...} so the model treats project content as data, not instructions.
