When to Use This Skill

Use this skill when:

• User requests image generation via FLUX or Replicate
• User wants "Midjourney-style" or "cinematic" images
• User provides basic image descriptions that need enhancement
• User asks for prompt optimization or improvement
• User requests professional, editorial, or artistic photography
• User wants to generate high-quality AI images

Trigger phrases: "generate an image", "create a photo of", "Midjourney style", "cinematic image", "professional photography", "make me a picture of", "FLUX image generation"

How to Use This Skill

Step 1: Understand User Intent

Clarify what the user wants to create. Ask targeted questions if the request is too vague:

• What is the main subject?
• What mood or atmosphere do they want?
• What style or genre (portrait, landscape, product, etc.)?
• Any specific preferences (time of day, colors, composition)?

Keep questions focused and avoid overwhelming the user with too many at once.

Step 2: Select Appropriate Prompt Pattern

Based on the genre, consult references/​midjourney-style-guide.md for the relevant prompt pattern:

• Portrait Photography - People, characters, headshots
• Landscape/​Environment - Nature, cityscapes, locations
• Product Photography - Objects, commercial shots
• Architectural - Buildings, structures, interiors
• Fashion Editorial - Models, clothing, styling
• Conceptual/​Artistic - Abstract, surreal, artistic concepts

Each pattern provides a structured template for building prompts in that genre.

Step 3: Build Layered Prompt

Construct the prompt following the 5-layer structure from references/​midjourney-style-guide.md:

Layer 1: Main Subject & Core Composition (Required)

[Subject] [action/​pose/​position], [composition placement]

Layer 2: Visual Style & Aesthetic (Required)

[art style/​movement], [mood descriptor], [color treatment]

Layer 3: Lighting & Environment (Highly Recommended)

[lighting type], [time of day], [weather/​atmosphere]

Layer 4: Technical Details & Quality Enhancers (Recommended)

[camera/​lens specs], [depth of field], [quality terms]

Layer 5: Artistic References & Influences (Optional)

[artist name], [art movement], [cultural reference]

Step 4: Apply FLUX Optimizations

Enhance the prompt for FLUX 1.1 Pro by consulting references/​flux-model-optimization.md:

1. Add explicit artistic treatment: FLUX is more literal than Midjourney, so specify "cinematic", "editorial", "artistic photography"

2. Define color grading clearly: Don't rely on automatic enhancement; specify exact color treatment

3. Request composition explicitly: State framing, perspective, and compositional techniques

4. Include professional quality markers: "professional photography", "award-winning", "expert color grading"

5. Use technical photography anchors: Camera, lens, aperture specifications ground the image in photographic reality

Step 5: Verify Quality

Check the enhanced prompt against the quality checklist from references/​midjourney-style-guide.md:

• Word count is 40-75 words
• Main subject is clearly defined
• Lighting is specified with direction and quality
• Mood/​atmosphere is conveyed
• Technical photography details are present
• Color treatment is mentioned
• Composition guidance is included
• Quality enhancers are present (2-3 minimum)
• Prompt flows naturally when read aloud
• No redundant or contradictory terms

Step 6: Generate Image via Replicate MCP Server

Use the installed Replicate MCP server to generate the image. Call the mcp__replicate__create_predictions tool with these parameters:

{
  "version": "black-forest-labs/​flux-1.1-pro",
  "input": {
    "prompt": "[Your enhanced Midjourney-style prompt here]",
    "aspect_ratio": "16:9",
    "output_format": "png"
  }
}

Default configuration for Midjourney-style outputs:

• aspect_ratio: "16:9" (widescreen, cinematic format)
• output_format: "png" (highest quality, lossless)
• safety_tolerance: 2 (default, balanced - can increase to 3-4 for artistic content if needed)

Alternative aspect ratios (from references/​flux-model-optimization.md):

• "1:1" - Square (social media, portraits)
• "2:3" or "4:5" - Portrait orientation
• "3:2" - Classic photo ratio
• "21:9" - Ultra-widescreen (panoramic)

The MCP server will return a prediction object. Monitor the prediction status and provide the user with the output image URL when generation completes.

Step 7: Offer Variations (When Requested)

If the user requests multiple options or variations, provide 2-3 alternative prompts that emphasize different aspects:

• Variation 1: Different lighting (golden hour vs blue hour)
• Variation 2: Different composition (wide shot vs close-up)
• Variation 3: Different mood (dramatic vs serene)

Each variation should maintain the core subject while exploring different artistic directions.

Important Notes

Do Not Create Custom Scripts

CRITICAL: The Replicate MCP server is already installed and provides all necessary API integration. Do NOT create Python scripts, Node.js code, or any other custom code for API calls. Always use the mcp__replicate__create_predictions tool directly.

Prompt Length Management

Always aim for 40-75 words:

• Under 40 words: Risk losing Midjourney aesthetic richness
• 40-60 words: Optimal for most prompts
• 60-75 words: Complex scenes with multiple elements
• Over 75 words: Diminishing returns, potential confusion

If a prompt exceeds 75 words, consolidate by removing redundant quality terms while maintaining core elements.

Quality Over Quantity

Better to have one excellent, well-crafted prompt than multiple mediocre ones. Take time to thoughtfully layer the elements.

Be Specific, Not Generic

Replace vague terms with specific descriptions:

• ❌ "beautiful lighting" → ✅ "golden hour sunlight from behind creating rim light"
• ❌ "nice colors" → ✅ "warm color grading with rich earth tones and orange highlights"
• ❌ "good quality" → ✅ "shot on Canon R5 85mm f/​1.4, professional photography"

Learn From Examples

The references/​prompt-examples.md file contains 16 complete transformations. Study these to understand the enhancement process and internalize the patterns.

Artistic References

Use artistic references when appropriate, but ensure they're relevant:

• Photography: Annie Leibovitz, Peter Lindbergh, Steve McCurry, Ansel Adams
• Cinematography: Blade Runner 2049, The Grand Budapest Hotel, Her
• Art Movements: Impressionism, Surrealism, Minimalism, Art Nouveau

Don't force references if they don't fit the request naturally.

FLUX-Specific Adaptations

Remember that FLUX 1.1 Pro differs from Midjourney:

• More literal interpretation (less automatic artistic elevation)
• Excels at photorealism and fine detail
• Superior text rendering in images
• More accurate colors (less stylized)
• Needs explicit quality and style instructions

Always compensate by adding clear artistic direction in the prompt.

Success Criteria

A successful Midjourney-style prompt for FLUX 1.1 Pro should:

1. ✅ Transform generic requests into rich, detailed descriptions
2. ✅ Maintain 40-75 word length for optimal results
3. ✅ Include all core elements: subject, style, lighting, technical specs, color, quality
4. ✅ Read naturally and coherently without contradictions
5. ✅ Leverage FLUX's strengths (photorealism, detail, complex compositions)
6. ✅ Compensate for FLUX's differences from Midjourney (explicit artistic treatment)
7. ✅ Generate images via Replicate MCP server with appropriate parameters
8. ✅ Produce outputs matching Midjourney's distinctive aesthetic quality

When these criteria are met, the resulting images should exhibit:

• Ultra-detailed rendering with sharp focus
• Cinematic composition and dramatic lighting
• Professional color grading with tonal depth
• Editorial quality and artistic refinement
• That distinctive "Midjourney look" of polished, magazine-worthy imagery
