SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

The banner-creator skill removes the friction of designing polished header and hero images by guiding an iterative AI generation workflow that ends with correctly cropped, platform-ready assets.

Core Features & Use Cases

  • AI banner generation: Produce many stylistic variations for banners, headers, hero images, covers, and readme/social image needs.
  • Requirement-driven prompts: Collect purpose, target ratio/size, style, brand text, and optional logo/character input before generating.
  • Crop to exact platform ratios: Generate at a wide ratio (e.g., 21:9) and then crop to common targets such as GitHub (2:1) or Twitter/X (3:1).
  • Interactive iteration loop: Let users pick favorites, refine based on feedback, regenerate improved variants, and update the preview.

Quick Start

Ask the assistant to create a GitHub README banner for your project, matching your preferred style, brand name, and logo character, then crop it to a 2:1 ratio.
