AI Review
Strong multi-step logo creation with real Python tooling and production HTML gallery. Scored 71 — strong execution hampered by undocumented nanobanana dependency. Style reference is excellent. OPC example images are project-specific but don't hurt the skill itself.

# Logo Creator Skill
Create professional logos through AI image generation with an iterative design process.
## Prerequisites
**Required API Keys (set in environment):**
- `GEMINI_API_KEY` - Get from [Google AI Studio](https://aistudio.google.com/apikey)
- `REMOVE_BG_API_KEY` - Get from [remove.bg](https://www.remove.bg/api)
- `RECRAFT_API_KEY` - Get from [recraft.ai](https://www.recraft.ai/)
**Required Skills:**
- `nanobanana` - AI image generation (Gemini 3 Pro Image)
## 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](./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:
```bash
# 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:
```bash
cp <skill_dir>/templates/preview.html .skill-archive/logo-creator/<yyyy-mm-dd-summaryname>/preview.html
```
Then open in default browser:
```bash
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):**
```bash
python3 <skill_dir>/scripts/crop_logo.py {input.png} {output-cropped.png}
```
**5b. Remove background:**
```bash
python3 <skill_dir>/scripts/remove_bg.py {input.png} {output-nobg.png}
```
**5c. Convert to SVG:**
```bash
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.
```
## Quick Reference
### Common Prompt Patterns
**Pixel Art:**
```
Pixel art {subject} logo, 8-bit retro style, black pixels on white background, {size}x{size} grid, minimalist icon
```
