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:

  1. Quick Review — 1 รอบวิเคราะห์ + แก้ไขถ้าจำเป็น
  2. Full Loop — วิเคราะห์ซ้ำจนกว่าจะผ่าน Quality Checklist ทุกข้อ
  3. 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?
  • Enough white space?

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

Integration Skills

Need Skill When to Use
