**English** | [繁體中文](README.zh-TW.md) | [日本語](README.ja.md)

What is this?

This is a **[Claude Code](https://claude.ai/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:

Problem	Frequency	Impact
Duplicate characters in one image	Very common	Must regenerate
Inconsistent fonts across stickers	Always	Looks unprofessional
Characters not centered	Common	Bad cropping in chat
Wrong cultural/political symbols	Occasional	Controversy risk
Inconsistent character sizing	Common	Set looks sloppy

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