Graphic Designer
Create effective visual communication through research-backed design principles.
Design = Communication + Aesthetics — Good design is invisible: it guides the eye, conveys the message, and feels "right" without effort.
Quick Workflow
1. PURPOSE — What should viewer DO after seeing this?
2. AUDIENCE — Who? What culture? What device?
3. HIERARCHY — What's #1, #2, #3 in importance?
4. LAYOUT — Sketch placement (Z or F pattern)
5. COLORS — 60-30-10 rule (check cultural meaning!)
6. TYPE — Max 2 fonts (1 display + 1 body)
7. ELEMENTS — Add graphics, icons, photos
8. REFINE — Remove until it breaks, then add back
9. CHECK — Squint test, mobile test, contrast check
10. REVIEW — Self-critique and iterate (optional loop)
Self-Review Loop (Auto-Improvement)
เมื่อสร้างผลงานแล้ว สามารถเปิด loop วิเคราะห์และปรับปรุงอัตโนมัติได้
เมื่อไหร่ควรถาม User
ถาม user ก่อนเริ่ม loop:
"ต้องการให้หนูเปิด Auto-Improvement Loop ไหมคะ? หนูจะวิเคราะห์ผลลัพธ์และปรับปรุงซ้ำจนกว่าจะได้คุณภาพที่ดีค่ะ"
Options:
- Quick Review — 1 รอบวิเคราะห์ + แก้ไขถ้าจำเป็น
- Full Loop — วิเคราะห์ซ้ำจนกว่าจะผ่าน Quality Checklist ทุกข้อ
- Skip — ส่งมอบเลย ไม่ต้อง review

Checklists
Before Designing
- What's the ONE message?
- Who's the audience? (culture, device)
- What emotion should it evoke?
Quality Check
- Clear hierarchy? (squint test)
- Readable at target size?
- Max 3-4 colors, 2-3 fonts?
- Contrast 4.5:1+? (WCAG AA)
- Aligned to grid?

Tools Integration
/geometric-elements — Decorative Assets
python scripts/generate.py shape --style star --color "#D4A84B" --size 100
python scripts/generate.py corner-accent --color "#D4A84B" --size 150
python scripts/generate.py line-divider --color "#D4A84B" --width 800
/art-director — Visual Impact (AI Image Prompts)
เมื่อต้องการรูปที่มี composition และ visual impact ดี:
1. Invoke /art-director พร้อมบอก context (slide theme, mood, brand)
2. ได้ prompt ที่พร้อมใช้กับ AI image generators
3. Gen รูปผ่าน /comfyui-user หรือ cloud API
AI Slide Backgrounds (Best Practices)
Workflow ที่ได้ผลดี:
1. ขอดู REFERENCE — ให้ user แชร์ตัวอย่าง slides ที่ชอบ
2. วิเคราะห์ PATTERNS — สรุป style (colors, elements, layout)
3. Gen ทั้ง BACKGROUND — ไม่แยกชิ้น, ไม่มี text
4. ITERATE — ปรับ size/position ตาม feedback
5. User วาง TEXT เอง — ยืดหยุ่นกว่า
✅ Do:
| Technique | Why |
|---|---|
| Gen complete background | ได้ภาพ cohesive สวยกว่าแยกชิ้น |
ใช้ --edit กับ logo เป็น ref |
AI เห็น shape จริง ไม่ต้องเดา |
| บอก "NO TEXT" | Text จาก AI มักผิด/ไม่สวย |
| White background | Nano Banana Pro ทำ transparent ไม่ได้ |
| เริ่ม simple | Logo เล็กมุมเดียว ดีกว่าเยอะทุกมุม |
❌ Don't:
| Technique | Problem |
|---|---|
| "TRANSPARENT BACKGROUND" | ได้ checkerboard ปลอม |
| อธิบาย logo shape เอง | AI ตีความผิด ใช้ --edit แทน |
| Gen แยกชิ้นแล้วประกอบ | Elements ไม่ match กัน |
| Decoration เยอะ | รกเกินไป ไม่ professional |
Prompt Template:
Professional presentation [TYPE] slide background,
16:9 aspect ratio. NO TEXT. [STYLE] STYLE.
BACKGROUND: [color, grid, gradient]
DECORATIVE: [small/subtle elements, specific corners]
LAYOUT: Leave [area] empty for [content]
COLORS: [hex codes]
/comfyui-user — Local Image Generation
สำหรับ gen รูปในเครื่องผ่าน ComfyUI:
1. Invoke /comfyui-user พร้อมบอกว่าต้องการรูปแบบไหน
2. เลือก workflow (turbo สำหรับ gen ใหม่, edit สำหรับแก้รูปเดิม)
3. ได้รูปพร้อมใช้ใน slides

How to use graphic-designer on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your development machine
- ›Node.js version 16.0+ with npm package manager (verify with
node --version) - ›Active project directory or workspace where you want to add graphic-designer
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
The skills CLI fetches graphic-designer from GitHub repository thepexcel/agent-skills and configures it for Cursor.
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Reload or restart Cursor to activate graphic-designer. Access the skill through slash commands (e.g., /graphic-designer) or your agent's skill management interface.
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
