Prompt Engineering Framework

The 5-Part Prompt Formula

Every effective prompt has 5 components:

1. Subject — What is the main thing?

"A luxury leather watch"
"A modern logo"
"An Instagram post graphic"

2. Description — What does it look like?

"with gold accents and brown leather strap"
"geometric style, minimalist design"
"vibrant colors, eye-catching composition"

3. Style — What's the artistic style?

"professional product photography"
"modern illustration"
"digital design"
"photorealistic"

4. Technical Details — Quality and format specs

"studio lighting, sharp focus, 4K, centered composition"
"high contrast, trending design, professional quality"
"detailed, well-lit, professional photography"

5. Mood/Aesthetic — What's the feeling?

"luxury and professional"
"energetic and modern"
"clean and minimalist"
"warm and inviting"

Complete Prompt Example

A luxury leather watch with gold accents and brown strap, 
professional product photography, studio lighting with rim light, 
centered composition, sharp focus, 4K, luxury and professional mood

Prompt Engineering Techniques

Technique 1: Be Specific

❌ Bad: "A watch"
✅ Good: "A luxury leather watch with gold accents on white background"

Technique 2: Use Descriptive Adjectives

❌ Bad: "A logo"
✅ Good: "A modern, geometric, minimalist logo in blue and white"

Technique 3: Reference Styles

❌ Bad: "A nice graphic"
✅ Good: "A graphic in the style of modern Instagram design trends"

Technique 4: Specify Quality

❌ Bad: "A photo"
✅ Good: "A professional 4K product photograph with studio lighting"

Technique 5: Include Composition

❌ Bad: "A person"
✅ Good: "A person in rule of thirds composition, natural lighting, centered"

Claude Code Integration

How to Use in Claude Code

Claude Code can directly generate images using the automation system:

from claude_integration import generate_asset

# Generate a single image
result = generate_asset(
    category="product-photos",
    name="luxury-watch",
    prompt="A luxury leather watch with gold accents on white background, professional product photography, studio lighting, 4K, sharp focus",
    size="1024x1024",
    num_variations=1
)

print(f"Generated: {result['images']}")

Setup for Claude Code

Ensure these files are in your project:

your-project/
├── vibe-creative-automation/
│   ├── fal_api.py
│   ├── creative_cli.py
│   ├── claude_integration.py
│   └── requirements.txt
└── assets/  (will be created automatically)

Set environment variable:

export FAL_API_KEY="your_key_here"

Install dependencies:

pip install requests

Claude Code Workflow

When you ask Claude: "Generate 3 variations of a product photo for my watch"

Claude will:

1. Read Image Generation skill to understand prompting
2. Read Creative Strategist to get your style
3. Craft the prompt combining both
4. Call automation system with the prompt
5. Generate 3 images using FLUX model
6. Save to folder like assets/product-photos/luxury-watch/
7. Show you results with file paths

Example: Claude Code Generates Product Photos

from claude_integration import generate_asset

# Your Creative Strategist style (from your style guide)
YOUR_STYLE = {
    "primary_style": "photorealistic",
    "mood": "professional and luxurious",
    "lighting": "studio lighting with rim light",
    "composition": "centered"
}

# Generate product photo using your style
prompt = f"""
A luxury leather watch with gold accents,
{YOUR_STYLE['primary_style']},
{YOUR_STYLE['mood']},
{YOUR_STYLE['lighting']},
{YOUR_STYLE['composition']},
white background,
4K,
sharp focus,
professional product photography
"""

result = generate_asset(
    category="product-photography",
    name="luxury-watch",
    prompt=prompt,
    size="1024x1024",
    num_variations=3
)

for img_path in result['images']:
    print(f"✅ Generated: {img_path}")

Batch Generation Example

from claude_integration import batch_generate_assets

# Generate multiple assets at once
assets = [
    {
        "type": "custom",
        "category": "product-photos",
        "name": "watch",
        "prompt": "Luxury watch, professional photography, studio lighting, 4K"
    },
    {
        "type": "custom",
        "category": "product-photos",
        "name": "wallet",
        "prompt": "Premium leather wallet, professional photography, studio lighting, 4K"
    },
    {
        "type": "custom",
        "category": "product-photos",
        "name": "sunglasses",
        "prompt": "Designer sunglasses, professional photography, studio lighting, 4K"
    }
]

results = batch_generate_assets(assets)

for result in results:
    print(f"{result['asset_name']}: {result['images']}")

Image Sizes

Choose the right size for your use case:

Size	Use Case	Speed	Detail
512x512	Testing, thumbnails	Fast	Good
768x768	Social media, web	Medium	Good
1024x1024	Product photos, hero images	Medium	Excellent
1536x1536	Large prints, high-res	Slow	Excellent
2048x2048	4K, maximum detail	Very Slow	Maximum

Generation Parameters

Guidance Scale (3.5 - 7.5)

Controls how strictly the model follows your prompt:

3.5 — More creative freedom, less literal
5.0 — Balanced (recommended)
7.5 — Strict adherence to prompt, more literal

Example:

# More creative
result = generate_asset(..., guidance_scale=3.5)

# Balanced (default)
result = generate_asset(..., guidance_scale=5.0)

# Strict
result = generate_asset(..., guidance_scale=7.5)

Inference Steps (20 - 50)

More steps = higher quality but slower:

20 — Fast, acceptable quality
28 — Balanced (default)
40 — High quality
50 — Maximum quality

Example:

# Fast generation
result = generate_asset(..., inference_steps=20)

# Balanced (default)
result = generate_asset(..., inference_steps=28)

# High quality
result = generate_asset(..., inference_steps=40)

Troubleshooting

Problem: Images don't match my style

Solution:

• Add more specific style descriptors to prompt
• Reference your Creative Strategist guide
• Test with different guidance scales
• Generate multiple variations

Problem: Generation is too slow

Solution:

• Use fal-ai/nano-banana-pro model
• Reduce image size to 768x768
• Reduce inference steps to 20

Problem: Images are too creative/not literal enough

Solution:

• Increase guidance scale to 7.5
• Be more specific in prompt
• Add more technical details

Problem: API errors

Solution:

• Verify FAL_API_KEY is set correctly
• Check internet connection
• Verify API key is valid
• Try again after a moment
