The system prompt
Definition and example
The system prompt is the focus of this lesson. The system prompt is the one place for fixed rules: what the bot may talk about, what it must never invent, and what it should do when it does not know. Keep it short and specific — every rule costs tokens on every request. The task asks you to apply that idea in a small example: What belongs in the system prompt. Before you run the code, predict what should happen. Then Inspect the printed output and the values your program uses and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
Run your code to see the output and the checks.

Why this works
Checks on this task:
- The program output must match “36 words in the system prompt mentions the phone: True”.
The task and step-by-step instructions are written as comments at the top of the editor. Change one relevant line, run it, and compare the result with these checks.
