What problem does it solve?

This Skill turns time-consuming illustration generation and cleanup into a repeatable pipeline that produces production-ready transparent assets without style drift.

Core Features & Use Cases

• Style-locked batch generation via visible browser automation: Drives a logged-in ChatGPT (image-2) or Gemini (Nano Banana) session using direct Playwright with persistent context and headless disabled, generating each illustration in a fresh chat to prevent style drift.
• Robust chroma-key background removal: Uses a dedicated magenta (#FF00FF) chroma-key + feathering + despill approach to produce clean transparent PNGs with no magenta fringe.
• iOS asset catalog integration: Writes @1x/@2x/@3x PNGs and generates the correct Contents.json, including padding/resizing rules so scales are integer point-equivalents for crisp rendering.
• Review and regeneration loop: Produces a review page for quick human approval and regenerates only the marked assets using the user’s correction notes.

Quick Start

Generate a batch of locked-style illustrations into the iOS asset catalog by instructing the Skill to replace placeholders for your onboarding scenes using design/style-lock.md as the style source.
