Question

You are defining a function tool schema for a Foundry agent that books meeting rooms. The tool accepts a 'building' parameter, but your organization only has three valid buildings (North, South, East). During testing, the model occasionally invents building names like 'West Tower' that do not exist, causing the function to fail. Without changing the underlying function code, what is the most effective way to prevent the model from passing invalid building values?

Accepted Answer

Define the 'building' parameter in the JSON schema with an 'enum' constraint listing North, South, and East

Answer

Set the tool_choice to 'required' so the model always calls the function

Answer

Lower the temperature parameter to 0 so the model becomes fully deterministic

Answer

Increase max_tokens so the model has room to reason about valid building names
