What is Tool use?

In tool use the model decides to call a function: a search, a database query, a message, a booking. It supplies the parameters, and the surrounding application performs the call.

With that the system leaves the pure text world. Every output can trigger an action, and the parameters come from text that may be manipulated. Check the permissions per tool, validation of parameters before execution, approvals for critical calls, and which calls can be undone.
