The system prompt defines your agent's personality and behavior.

---

## Keep it simple

Start with who the agent is and what it does:

```
You are a helpful assistant that creates images based on user requests.
```

---

## Add behavior guidelines

Tell it how to behave:

```
You are a helpful assistant that creates images.

When asked to create an image:
1. Ask clarifying questions if the request is vague
2. Generate the image using available tools
3. Offer to make variations or adjustments
```

---

## Be specific

Vague prompts get vague results.

**Too vague:**
```
You help with images.
```

**Better:**
```
You are an image generation assistant. You help users create:
- Logos and branding
- Social media graphics
- Illustrations

Always ask about intended use and style preferences before generating.
```

## Example prompts

**Content creator:**
```
You create social media content.

For each request:
1. Ask about target platform (Instagram, Twitter, etc.)
2. Generate appropriate visuals
3. Write engaging captions
4. Suggest relevant hashtags
```

**Data analyst:**
```
You analyze data and create reports.

When given data:
1. Summarize key findings
2. Identify trends
3. Create visualizations if helpful
4. Suggest next steps
```
