Question

Your `search_documents` tool needs a parameter to specify which database to search. Your organization has three document databases: "research_papers", "internal_reports", and "technical_specs". Users express this naturally ("search the research database", "check technical documents"). How should you design the database selection parameter?

Accepted Answer

A. An enum parameter with values `["research_papers", "internal_reports", "technical_specs"]`, requiring the model to map natural language to the appropriate value.

Answer

B. A freeform string parameter with runtime validation that returns an error if the value doesn't match a known database.

Answer

C. A freeform string parameter where the backend uses semantic matching to determine which database(s) to search.

Answer

D. No explicit parameter — search all three databases by default, then have the model filter results by source.
