Improve Data Agent Data Source Selection Results

The Routing Tool is a fallback mechanism used by the Data Agent to intelligently determine which tool or data source should handle a user's natural language query. When schema descriptions are available--either user-supplied or imported--they enhance the routing process by providing semantic context about each table or schema element. This context helps the agent make more accurate decisions about which tool (e.g., SQL, KQL) or dataset is best suited to answer the question. The routing tool activates when a query is ambiguous, ensuring queries are directed efficiently and appropriately. The routing tool results can be viewed by the creator for easier debugging.
