Create Sticker Skill

Overview

Generate LINE-style character stickers using Google Gemini's image generation API. Each sticker has a creative, unique pose with consistent character appearance.

How to Use

To create a sticker, run the create_sticker.ts script via terminal:

deno run --allow-all scripts/create_sticker.ts "pose and expression description"

Or with a custom character prompt:

deno run --allow-all scripts/create_sticker.ts "waving hello" --character "Chibi anime girl with blue hair and cat ears"

Or with a reference image:

deno run --allow-all scripts/create_sticker.ts "waving hello" --reference path/to/reference.jpg

API Configuration

• Model: gemini-2.0-flash-preview-image-generation (Gemini image generation)
• Authentication: GEMINI_API_KEY environment variable (set via frontend settings)

Output

Stickers are saved as PNG files in the stickers/ directory. The moodboard panel in the UI automatically displays new stickers.

Prompt Guidelines

✅ DO

• Keep action prompts short and focused on pose + expression + energy
• Describe specific facial expressions (half-lidded eyes, puffed cheeks, squinting)
• Use dynamic verbs (tilting, peeking, squeezing, leaning)

❌ DON'T

• Don't write long paragraphs — keep it concise
• Don't request full body — upper body framing works best for stickers
• Don't use thick/bold outline style — thin delicate lines only
