AI can talk, but how do I get it to actually check the database or make a request?
Can you check whether I’m free tomorrow afternoon?
Request execution based on tool definitions: Tools are defined with a name, description, and typed parameters. The model fills parameters to request a tool call, but this is only an invocation request—the model does not run the tool directly.
The application validates permissions and parameters: It checks whether the tool is permitted, whether parameters make sense, and whether the user has access.
Real execution results return to the model: Only the executed result from the external tool comes back to the model to formulate the final answer.
Validate meeting creation with a mock or dedicated test calendar, not a real schedule. Show the proposed time, attendees, and title before the call; simulate one success and one permission denial, reporting only from the actual tool result. Delete any event created in the test calendar afterward.
