Learn the fundamentals, then watch a simple enterprise agent use two tools.
Estimated time: 10 to 15 minutes · Level: Beginner
Model thinks. Tool does. Agent decides. Harness controls.
A model on its own only generates text. Give it tools, instructions, and a controlled loop and it becomes an agent: a system that decides what to do, takes action, and answers. The harness around it is what makes it reliable enough for enterprise use.
The example you will use
An employee leave assistant with exactly two tools: one checks an employee's leave balance, the other retrieves the company leave policy. It is kept simple on purpose. The same pattern later connects to SAP, Workday, or any enterprise system.
Sample company data. Not connected to a real HR system.
