用 AI 設計 LINE 貼圖的完整流程，從概念到上架。 A Claude Code skill for designing LINE sticker sets with AI — from concept to submission-ready files.

English | 繁體中文 | 日本語

What is this?

This is a Claude Code skill — a structured set of instructions and scripts that guides Claude through the complete LINE sticker creation pipeline:

1. Theme & Planning — Character concept, expression list, set composition
2. Character Design — Style anchor prompt for visual consistency
3. Batch Generation — AI image generation with quality controls
4. Quality Review — Systematic checklist to catch common AI generation issues
5. Post-Processing — Automated background removal, resizing, and formatting
6. Final Verification — Format compliance and submission readiness

Why a Skill?

AI image generation is powerful but unpredictable. Without guardrails, you’ll hit these problems:

This skill encodes hard-won lessons into reusable instructions, so you don’t have to learn them the hard way.

Quick Start

1. Install the Skill

Copy the skill to your Claude Code skills directory:

# Create the skill directory
mkdir -p ~/.claude/skills/line-sticker-maker

# Copy files
cp SKILL.md ~/.claude/skills/line-sticker-maker/
cp -r scripts/ ~/.claude/skills/line-sticker-maker/scripts/

2. Install Dependencies

The post-processing script requires Pillow:

pip install Pillow

3. Use It

In Claude Code, just ask:

幫我設計一組 16 張的 LINE 貼圖，主題是 [你的主題]

or

Design a set of 16 LINE stickers featuring [your character concept]

Claude will automatically invoke the skill and guide you through the full pipeline.

The Post-Processing Script

scripts/process_stickers.py converts raw AI-generated images to LINE-ready format:

# Basic usage
python3 scripts/process_stickers.py \
  --input-dir ./my-stickers \
  --output-dir ./line_format

# With per-sticker padding adjustments
