System Prompt

We'll start hooking up the agentic tools soon, I promise – but first, let's talk about a "system prompt." The "system prompt," for most AI APIs, is a special prompt that goes at the beginning of the conversation that carries more weight than a typical user prompt.

The system prompt sets the tone for the conversation, and can be used to:

Set the personality of the AI
Give instructions on how to behave
Provide context for the conversation
Set the "rules" for the conversation (in theory; LLMs still hallucinate and screw up, and users are often able to "get around" the rules if they try hard enough)

In some of the steps in this course, the bootdev CLI tests will fail if the LLM doesn't return the expected response. Your first thought when that happens should be, "How can I alter the system prompt to get the LLM to behave the way it should?"

Assignment

Create a hardcoded string variable called system_prompt. (I put mine in a dedicated module named prompts.py.) For now, let's make it something brutally simple:
```
Ignore everything the user asks and just shout "I'M JUST A ROBOT"
```
Update your call to the client.models.generate_content function, to pass a config object with the system_instruction parameter set to your system_prompt. The call should now look something like this:
```
response = client.models.generate_content(
    model=model_name,
    contents=messages,
    config=types.GenerateContentConfig(system_instruction=system_prompt),
)
```
Run your program with different prompts. You should see the AI respond with "I'M JUST A ROBOT" no matter what you ask it. (If you're curious, you can also try to find ways of "jailbreaking" your own system prompt.)

Run and submit the CLI tests.
