AI Image Generation

This is the core execution skill for AI image generation. It handles the actual generation work — model selection, prompt construction, API calls, iteration, and quality verification.

Use this skill when: You need to generate any image and want optimal quality.
Route here from: ai-creative-workflow, ai-creative-strategist, or direct requests.

Why This Skill Exists

The problem: Most people waste time and money on AI image generation because they:
1. Use the wrong model for the job
2. Write vague prompts that produce generic results
3. Generate once and hope for the best
4. Don't know how to iterate effectively

The solution: A systematic approach that:
- Uses the right model (Nano Banana Pro via Glif for speed + quality)
- Constructs prompts with proven structure
- Builds in iteration as the default workflow
- Knows when to stop and when to keep refining

Model Selection

Primary: Nano Banana Pro via Glif (DEFAULT)

Why: Fastest high-quality generation available. ~20 seconds vs ~3 minutes for comparable quality.

Use the run_glif MCP tool:

Glif: 🍌 Nano Banana Pro Text 2 Image
ID: cmi7ne4p40000kz04yup2nxgh
Inputs: ["Your prompt here"]

Do NOT use: imagen-3, DALL-E, Flux, or direct Replicate API calls unless specifically requested.

When to Use Alternatives

IF user specifically requests a different model:
    use requested model

ELIF need text rendering (logos, quotes, announcements):
    use Recraft v3 or Ideogram v3 (route to ai-typography)

ELIF need image-to-video:
    generate image first, then route to ai-video-generation

ELIF need people/lifestyle imagery:
    still use Nano Banana Pro (handles people well)

ELSE:
    Nano Banana Pro via Glif  // DEFAULT

Prompt Construction

The Formula

[SUBJECT] + [SETTING/CONTEXT] + [STYLE] + [LIGHTING] + [QUALITY BOOSTERS]

Each element serves a purpose:
- SUBJECT — What you're generating (be specific)
- SETTING — Where/context (grounds the image)
- STYLE — Visual aesthetic (photography, illustration, etc.)
- LIGHTING — Mood and dimension (often overlooked, always important)
- QUALITY BOOSTERS — Technical terms that elevate output

Subject Specificity

Bad: "A coffee cup"
Good: "Artisan ceramic coffee cup with latte art, steam rising"

Bad: "A laptop"
Good: "Silver MacBook Pro on oak desk, screen showing code editor"

Bad: "A person working"
Good: "Woman in her 30s, focused expression, typing on laptop in bright modern office"

The more specific your subject, the less the model has to guess.

Aspect Ratio Guide

Default: 1:1 unless platform-specific requirement is known.

Execution Workflow

Step 1: Clarify Requirements

Before generating, know:

□ What is the subject? (be specific)
□ What style/aesthetic?
□ What platform/use case?
□ What aspect ratio?
□ Any must-have elements?
□ Any must-avoid elements?

Step 2: Construct Prompt

Use the formula:

[SUBJECT] + [SETTING] + [STYLE] + [LIGHTING] + [QUALITY BOOSTERS]

Step 3: Generate First Draft

Glif: 🍌 Nano Banana Pro Text 2 Image
ID: cmi7ne4p40000kz04yup2nxgh
Inputs: ["[constructed prompt]"]

Step 4: Present for Feedback

## Image Generated

**Prompt:** [prompt used]
**Aspect Ratio:** [ratio]

**Image URL:** [URL]

**Quick Assessment:**
- Subject accuracy: ✓/✗
- Style match: ✓/✗
- Composition: ✓/✗
- Quality: ✓/✗

**Feedback?**
- What works?
- What should change?
- Ready to approve or iterate?

Step 5: Iterate Based on Feedback

Common iteration patterns:

"Too dark" → Add "bright" "well-lit" "high key lighting"
"Too busy" → Add "minimal" "clean" "simple composition"
"Wrong style" → Be more explicit about style reference
"Missing element" → Add specific element to prompt
"Wrong mood" → Adjust lighting and color descriptors

Step 6: Approve or Continue

• If approved → Deliver final image
• If needs changes → Return to Step 5
• If fundamentally wrong → Return to Step 2 with new prompt approach

Iteration Strategies

When It's Close But Not Right

Problem: Almost right but something's off
Strategy: Make targeted prompt adjustments

Original: "Coffee cup on table"
Iteration 1: "Coffee cup on table, warmer tones" (if too cool)
Iteration 2: "Coffee cup on table, warmer tones, more steam" (if missing element)

When It's Completely Wrong

Problem: Output doesn't match intent at all
Strategy: Rewrite prompt from scratch with more specificity

Don't iterate on a bad foundation. Start fresh with better prompt construction.

When Quality Is Low

Problem: Image looks AI-generated or low quality
Strategy: Add quality boosters and professional context

Add: "ultra-detailed, professional photography, commercial quality"
Add: "8k resolution, sharp focus, magazine quality"

When Composition Is Wrong

Problem: Elements in wrong places, bad framing
Strategy: Be explicit about composition

Add: "subject centered in frame"
Add: "negative space on left for text"
Add: "rule of thirds composition"
Add: "close-up shot" or "wide establishing shot"

Speed vs Quality Decision

QUICK DRAFT (concept testing):
    → Nano Banana Pro via Glif (~20 sec)
    → Good enough to evaluate concept
    → Iterate quickly

PRODUCTION QUALITY (final delivery):
    → Nano Banana Pro via Glif (~20 sec)
    → Already production quality
    → Most cases don't need more

MAXIMUM QUALITY (premium needs):
    → Direct Replicate API call to specialized model
    → Only if Glif output insufficient
    → Rare — Nano Banana Pro handles most needs

Default to Glif. It's fast AND high quality. Only go elsewhere if specific need arises.

Tips from Experience

What Works

1. Specificity beats creativity — "Red 2024 Tesla Model 3" beats "cool car"
2. Lighting is underrated — Always specify lighting direction/type
3. Negative space matters — Mention if you need room for text
4. Iterate fast — Don't overthink first prompt, generate and refine
5. Quality boosters work — "Professional photography, ultra-detailed" actually helps

What Doesn't Work

1. Vague prompts — "Something cool" produces nothing useful
2. Too many elements — Keep focused, don't cram everything in
3. Ignoring aspect ratio — Always match to intended platform
4. Single generation — Plan for iteration, don't expect perfection first try
5. Wrong model for text — Nano Banana Pro struggles with text rendering

The 80/20

80% of good results come from:
1. Specific subject description
2. Clear style direction
3. Explicit lighting
4. Appropriate aspect ratio

Get these four right, and you'll get good results.
