ai-social-graphics（AI 社交图形）

AI Social Graphics

This skill creates platform-optimized graphics for social media. Not generic images that happen to be the right size — graphics engineered for each platform's specific algorithm, user behavior, and visual language.

Use this skill when: You need graphics for specific social platforms or ads. Route here from: ai-creative-workflow when platform is specified.

Why This Skill Exists

The problem: Every platform has different:

• Aspect ratios and safe zones
• Visual languages that perform
• Algorithm preferences
• User attention patterns
• Text overlay requirements

Generic "social media graphics" underperform because they ignore these differences.

The solution: Platform-specific knowledge built into prompt construction, so every graphic is optimized for where it will live.

Model

ALWAYS use Nano Banana Pro via Glif.

Exception: For text-heavy graphics (quote cards, announcement graphics), route to ai-typography which uses Recraft v3 or Ideogram v3 for superior text rendering.

Style Exploration (Before Execution)

Critical insight from ai-creative-strategist: Don't lock into one style early. Generate multiple genuinely DIFFERENT visual directions first.

Why This Matters for Social Graphics

Social graphics live in noisy feeds. The "right" style isn't obvious — it depends on:

• Platform visual language
• Audience expectations
• Competitive landscape
• Brand positioning

One style = hope. Multiple styles = informed choice.

The Style Exploration Process

1. GENERATE 4-5 DIFFERENT STYLES
   → Not variations of one style
   → Genuinely different visual languages
   → Same subject, different aesthetic approaches

2. IDENTIFY WINNER
   → Which stops the scroll?
   → Which matches platform vibe?
   → Which feels most "brand"?

3. EXTRACT PRINCIPLES
   → What makes this style work?
   → Color palette?
   → Composition approach?
   → Lighting mood?

4. APPLY TO FORMATS
   → Same principles, different platforms
   → Build content SYSTEM
   → Repeatable, not one-off

Style Exploration Prompt Template

For any new social graphics project, generate these 5 directions:

Style 1 - Clean Minimal:
[Subject] for [platform], clean minimal aesthetic, white space,
single focal point, modern typography space, sophisticated restraint

Style 2 - Bold Vibrant:
[Subject] for [platform], bold vibrant colors, high contrast,
dynamic composition, energetic attention-grabbing

Style 3 - Warm Lifestyle:
[Subject] for [platform], warm lifestyle aesthetic, natural tones,
authentic feeling, relatable human-centered

Style 4 - Dark & Premium:
[Subject] for [platform], dark moody aesthetic, premium feel,
sophisticated lighting, luxury positioning

Style 5 - Playful Creative:
[Subject] for [platform], playful creative aesthetic, unexpected angles,
personality-forward, memorable differentiation

Style Decision Framework

After generating options:

Extract Principles Template

Once winner is identified, document:

## Winning Style: [Name]

**What makes it work:**
- Color palette: [specific colors]
- Composition: [approach]
- Lighting: [mood/direction]
- Typography space: [how handled]
- Mood: [feeling it creates]

**Apply to other platforms:**
- Instagram Feed: [how to adapt]
- LinkedIn: [how to adapt]
- Twitter: [how to adapt]
- etc.

This creates a repeatable SYSTEM, not just one graphic.

Execution Workflow

Step 1: Platform Requirements

□ Which platform?
□ Which placement? (feed/stories/cover/etc.)
□ Aspect ratio confirmed?
□ Safe zones understood?

Step 2: Content Type

□ What type of content? (announcement/quote/product/etc.)
□ Text overlay needed?
□ Brand colors required?
□ Specific elements must include?

Step 3: Construct Platform-Optimized Prompt

Use templates above, customize for specific need.

Step 4: Generate

Glif: 🍌 Nano Banana Pro Text 2 Image
ID: cmi7ne4p40000kz04yup2nxgh
Inputs: ["[platform-specific prompt]"]

Step 5: Platform-Specific Review

Check against platform requirements:

• Correct ratio?
• Safe zones respected?
• Visual language matches platform?
• Scroll-stopping quality?
• Text space if needed?

Step 6: Iterate or Approve

Multi-Platform Scaling

When one concept needs multiple platforms:

Strategy: Generate Primary, Then Adapt

1. Generate for PRIMARY platform (where it matters most)
2. Approve composition and style
3. Generate variants for other platforms
   - Adjust aspect ratio
   - Adjust composition for different safe zones
   - Maintain visual consistency

Common Issues & Solutions

Tips from Experience

What Works

1. Platform-first thinking — Start with where it lives, not what it shows
2. Ratio is non-negotiable — Wrong ratio = wrong everything
3. Safe zones matter — Platform UI will cover content
4. Visual language matching — LinkedIn ≠ TikTok aesthetically
5. Bold beats subtle — Social is noisy, you need to pop

What Doesn't Work

1. One size fits all — Generic "social media" prompts
2. Ignoring platform culture — Too polished for TikTok, too casual for LinkedIn
3. Forgetting mobile — Most viewing is phone-sized
4. Text-heavy images — Most platforms deprioritize
5. Subtle visuals — Get lost in the scroll

The 80/20

80% of social graphic success comes from:

1. Correct aspect ratio
2. Platform-appropriate visual language
3. Scroll-stopping contrast/colors
4. Clear focal point

Get these four right and you'll outperform most content.
