Using Style Presets

In generate_image

{
  "tool": "generate_image",
  "params": {
    "prompt": "a sunset over mountains",
    "style_preset_name": "Cinematic"
  }
}

Or by ID:

{
  "tool": "generate_image",
  "params": {
    "prompt": "a sunset over mountains",
    "style_preset_id": 5
  }
}

Override Preset Settings

You can override preset defaults:

{
  "tool": "generate_image",
  "params": {
    "prompt": "a sunset over mountains",
    "style_preset_name": "Cinematic",
    "aspect_ratio": "square"
  }
}

The explicit aspect_ratio overrides the preset's default 16:9.

Best Practices

1. Be Specific

// Too vague
"nice style"

// Better
"soft pastel colors, gentle gradients, kawaii aesthetic, rounded shapes"

2. Match Negative to Positive

If your style is "watercolor":

{
  "prompt": "watercolor painting, soft washes",
  "negative_prompt": "digital art, 3D render, photograph, oil painting, sharp edges"
}

3. Keep Prompt Length Balanced

• Too short: Not enough guidance
• Too long: May overwhelm subject

Good length: 20-50 words

4. Test Before Committing

Generate test images with different subjects:

Generate a portrait using my new "Test Style"
Generate a landscape using my new "Test Style"
Generate a still life using my new "Test Style"

5. Use System Instructions Wisely

System instructions guide overall behavior:

// Good
"Create images suitable for children's book illustrations"
"Act as a professional food photographer"

// Less useful
"Make nice images"
