+# Banner Design - Multi-Format Creative Banner System
+
+Design banners across social, ads, web, and print formats. Generates multiple art direction options per request with AI-powered visual elements. This skill handles banner design only. Does NOT handle video editing, full website design, or print production.
+
+## When to Activate
+
+- User requests banner, cover, or header design
+- Social media cover/header creation
+- Ad banner or display ad design
+- Website hero section visual design
+- Event/print banner design
+- Creative asset generation for campaigns
+
+## Prerequisites
+
+**Python:** This skill uses Python scripts. On Windows, use `python` instead of `python3` (e.g., `python scripts/search.py` instead of `python3 scripts/search.py`).
+
+## Workflow
+
+### Step 1: Gather Requirements (AskUserQuestion)
+
+Collect via AskUserQuestion:
+
+1. **Purpose** — social cover, ad banner, website hero, print, or creative asset?
+2. **Platform/size** — which platform or custom dimensions?
+3. **Content** — headline, subtext, CTA, logo placement?
+4. **Brand** — existing brand guidelines? (check `docs/brand-guidelines.md`)
+5. **Style preference** — any art direction? (show style options if unsure)
+6. **Quantity** — how many options to generate? (default: 3)
+
+### Step 2: Research & Art Direction
+
+1. Activate `ui-ux-pro-max` skill for design intelligence
+2. Use Chrome browser to research Pinterest for design references:
+   ```
+   Navigate to pinterest.com → search "[purpose] banner design [style]"
+   Screenshot 3-5 reference pins for art direction inspiration
+   ```
+3. Select 2-3 complementary art direction styles from references: `references/banner-sizes-and-styles.md`
+
+### Step 3: Design & Generate Options
+
+For each art direction option:
+
+1. **Create HTML/CSS banner** using `frontend-design` skill
+
+   - Use exact platform dimensions from size reference
+   - Apply safe zone rules (critical content in central 70-80%)
+   - Max 2 typefaces, single CTA, 4.5:1 contrast ratio
+   - Inject brand context via `inject-brand-context.cjs`
+
+2. **Generate visual elements** with `ai-artist` + `ai-multimodal` skills
+
+   **a) Search prompt inspiration** (6000+ examples in ai-artist):
+
+   ```bash
+   python3 .claude/skills/ai-artist/scripts/search.py "<banner style keywords>"
+   ```
+
+   **b) Generate with Standard model** (fast, good for backgrounds/patterns):
+
+   ```bash
+   .claude/skills/.venv/bin/python3 .claude/skills/ai-multimodal/scripts/gemini_batch_process.py \
+     --task generate --model gemini-2.5-flash-image \
+     --prompt "<banner visual prompt>" --aspect-ratio <platform-ratio> \
+     --size 2K --output assets/banners/
+   ```
+
+   **c) Generate with Pro model** (4K, complex illustrations/hero visuals):
+
+   ```bash
+   .claude/skills/.venv/bin/python3 .claude/skills/ai-multimodal/scripts/gemini_batch_process.py \
+     --task generate --model gemini-3-pro-image-preview \
+     --prompt "<creative banner prompt>" --aspect-ratio <platform-ratio> \
+     --size 4K --output assets/banners/
+   ```
+
+   **When to use which model:** | Use Case | Model | Quality | |----------|-------|---------| | Backgrounds, gradients, patterns | Standard (Flash) | 2K, fast | | Hero illustrations, product shots | Pro | 4K, detailed | | Photorealistic scenes, complex art | Pro | 4K, best quality | | Quick iterations, A/B variants | Standard (Flash) | 2K, fast |
+
+   **Aspect ratios:** `1:1`, `16:9`, `9:16`, `3:4`, `4:3`, `2:3`, `3:2` Match to platform - e.g., Twitter header = `3:1` (use `3:2` closest), Instagram story = `9:16`
+
+   **Pro model prompt tips** (see `ai-artist` references/nano-banana-pro-examples.md):
+
+   - Be descriptive: style, lighting, mood, composition, color palette
+   - Include art direction: "minimalist flat design", "cyberpunk neon", "editorial photography"
+   - Specify no-text: "no text, no letters, no words" (text overlaid in HTML step)
+
+3. **Compose final banner** — overlay text, CTA, logo on generated visual in HTML/CSS
+
+### Step 4: Export Banners to Images
+
+After designing HTML banners, export each to PNG using `chrome-devtools` skill:
+
+1. **Serve HTML files** via local server (python http.server or similar)
+2. **Screenshot each banner** at exact platform dimensions:
+   ```bash
+   # Export banner to PNG at exact dimensions
+   node .claude/skills/chrome-devtools/scripts/screenshot.js \
+     --url "http://localhost:8765/banner-01-minimalist.html" \
+     --width 1500 --height 500 \
+     --output "assets/banners/{campaign}/{variant}-{size}.png"
+   ```
+3. **Auto-compress** if >5MB (Sharp compression built-in):
+   ```bash
+   # With custom max size threshold
+   node .claude/skills/chrome-devtools/scripts/screenshot.js \
+     --url "http://localhost:8765/banner-02-gradient.html" \
+     --width 1500 --height 500 --max-size 3 \
+     --output "assets/banners/{campaign}/{variant}-{size}.png"
+   ```
+
+**Output path convention** (per `assets-organizing` skill):
+
+```
+assets/banners/{campaign}/
+├── minimalist-1500x500.png
+├── gradient-1500x500.png
+├── bold-type-1500x500.png
+├── minimalist-1080x1080.png    # if multi-size requested
+└── ...
+```
+
+- Use kebab-case for filenames: `{style}-{width}x{height}.{ext}`
+- Date prefix for time-sensitive campaigns: `{YYMMDD}-{style}-{size}.png`
+- Campaign folder groups all variants together
+
+### Step 5: Present Options & Iterate
+
+Present all exported images side-by-side. For each option show:
+
+- Art direction style name
+- Exported PNG preview (use `ai-multimodal` skill to display if needed)
+- Key design rationale
+- File path & dimensions
+
+Iterate based on user feedback until approved.

+
+## Design Principles
+
+### Visual Hierarchy (3-Zone Rule)
+
+- **Top**: Logo or main value prop
+- **Middle**: Supporting message + visuals
+- **Bottom**: CTA (button/QR/URL)
+
+### Safe Zones
+
+- Critical content in central 70-80% of canvas
+- Avoid text/CTA within 50-100px of edges
+- YouTube: 1546 × 423px safe area inside 2560 × 1440
+- Meta/Instagram: central 80% to avoid UI chrome
+
+### CTA Rules
+
+- One CTA per banner
+- High contrast vs background
+- Bottom-right placement (terminal area)
+- Min 44px height for mobile tap targets
+- Action verbs: "Get", "Start", "Download", "Claim"
+
+### Typography
+
+- Max 2 typefaces per banner
+- Min 16px body, ≥32px headline (digital)
+- Min 4.5:1 contrast ratio
+- Max 7 words/line, 3 lines for ads
+
+### Text-to-Image Ratio
+
+- Ads: under 20% text (Meta penalizes)
+- Social covers: 60/40 image-to-text
+- Print: 70pt+ headlines for 3-5m viewing distance
+
+### Print Specs
+
+- 300 DPI minimum (150 DPI for large format)
+- 3-5mm bleed all sides
+- CMYK color mode
+- 1pt per foot viewing distance rule
