Logo Creator

File Output Location

All generated files should be saved to the .skill-archive directory:

.skill-archive/logo-creator/<yyyy-mm-dd-summaryname>/

Example:

.skill-archive/logo-creator/2026-01-18-opc-logo/
  logo-01.png
  logo-02.png
  ...
  logo-09-cropped.png
  logo-09-nobg.png
  logo-09.svg
  preview.html

Guidelines:

• Use current date in format yyyy-mm-dd
• Add short summary name (project/brand name, kebab-case)
• Create directory before generating first logo
• Keep all variations and iterations in same folder
• Final approved logo should be copied to user's desired location

Workflow

Step 1: Discovery & Requirements

Before generating, gather requirements from user:

Ask about:

1. Project/Brand name - What is the logo for?

2. Style preference - See references/styles.md for options:

   • Pixel art / 8-bit retro
   • Minimalist / flat design
   • 3D / isometric
   • Hand-drawn / sketch
   • Mascot / character
   • Monogram / lettermark
   • Abstract / geometric

3. Aspect ratio - Default is 1:1 (square), options:

   • 1:1 - Square (favicons, app icons)
   • 16:9 - Wide (headers, banners)
   • 4:3 - Standard
   • 2:3 - Portrait

4. Color preferences:

   • Monochrome (black & white)
   • Specific brand colors
   • Let AI decide

5. Reference images - Any existing logos or styles to reference?

Wait for user confirmation before proceeding!

Step 2: Generate Logo Variations

Generate 20 logo variations (default) using the nanobanana skill:

# Generate single logo
python3 <nanobanana_skill_dir>/scripts/generate.py "{style} logo for {brand}, {description}, {colors}" \
  --ratio 1:1 -o .skill-archive/logo-creator/<date-name>/logo-01.png

# Batch generate 20 logos
python3 <nanobanana_skill_dir>/scripts/batch_generate.py "{style} logo for {brand}, {description}, {colors}" \
  -n 20 --ratio 1:1 -d .skill-archive/logo-creator/<date-name> -p logo

Guidelines:

• Use batch_generate.py for multiple variations (includes auto-delay)
• Save to .skill-archive/logo-creator/<yyyy-mm-dd-summaryname>/ directory
• Use sequential naming: logo-01.png, logo-02.png, etc.

Prompt Tips:

• Include style keywords: "pixel art", "minimalist", "8-bit", "flat design"
• Specify colors: "black on white", "monochrome", "blue gradient"
• Add context: "tech startup", "food brand", "gaming company"
• Request format: "icon", "emblem", "mascot", "lettermark"

Step 3: Create HTML Preview

Copy the preview template and open in browser:

cp <skill_dir>/templates/preview.html .skill-archive/logo-creator/<yyyy-mm-dd-summaryname>/preview.html

Then open in default browser:

open .skill-archive/logo-creator/<yyyy-mm-dd-summaryname>/preview.html

IMPORTANT: Update the HTML to include the correct number of logos generated.

Step 4: Iterate with User

Ask user which logos they prefer:

• "Which logos do you like? (e.g., #5, #12, #18)"
• "What do you like about them?"
• "Any changes you'd want?"

Based on feedback:

1. Generate 10-20 more variations of favorite styles
2. Use naming: logo-{original}-v{n}.png (e.g., logo-05-v1.png)
3. Update HTML preview
4. Repeat until user selects final logo

Step 5: Finalize Logo

Once user approves a logo, process it:

5a. Crop whitespace (make 1:1 with no margins):

python3 <skill_dir>/scripts/crop_logo.py {input.png} {output-cropped.png}

5b. Remove background:

python3 <skill_dir>/scripts/remove_bg.py {input.png} {output-nobg.png}

5c. Convert to SVG:

python3 <skill_dir>/scripts/vectorize.py {input.png} {output.svg}

Step 6: Deliver Final Assets

Present final deliverables:

## Final Logo Assets

| File | Description | Size |
|------|-------------|------|
| logo.png | Original | 1024x1024 |
| logo-cropped.png | No margins, 1:1 | ~800x800 |
| logo-nobg.png | Transparent background | ~800x800 |
| logo.svg | Vector (scalable) | ~20KB |

All files saved to: `.skill-archive/logo-creator/<yyyy-mm-dd-summaryname>/`
Copy final logo to user's desired location.
