Tools and Function Calling
Tools and Function Calling
A tool is a named capability with a contract: a name, inputs, and a result the model can read. Function calling is how the model asks to use that capability instead of pretending it already knows the answer.
In this lesson you build a tiny inspector: a page that shows one real tool call (name, input, result) so you can see the glass window, not just the chat.
Learning outcomes
- Describe a tool as name + input schema + result
- Show a failed call vs a successful call
- Refuse to invent a result you did not run
