Create Sticker Skill

Overview

Generate LINE-style character stickers. Each sticker has a creative, unique pose with consistent character appearance. Generates on light gray background, then auto-removes background to produce transparent PNG ready for messaging platforms.

Workflow

1. Generate — Call Google Gemini with character reference + sticker prompt
2. Save raw — Save image with gray background
3. Remove background — Flood fill gray to transparent (preserves white border + clothing)
4. Center & fill — Center content and scale up until edges touch canvas boundary
5. Send — Send to user for review
