Who it is forA community creator making posts and posters featuring Whale-chan for different platforms.

The problemEach platform wants a different aspect ratio, and regenerating keeps changing the character's details.

The outcomeClean posters in portrait and square formats with hair gradient, whale-fin ears, tail and maid uniform kept consistent.

What you need first

  • Python environment, as described in the Installation & Environment Setup section of the README
  • Image generation access as set up through the README's local toolchain or agent skills
  • A clear idea of the target use: poster, sticker, banner, or comic

Steps

  1. Install the skills from the repo's skills/ directory into your agent
  2. Ask the whalechan-image-character skill for a poster, naming the form, such as standard for large posters
  3. Request 9:16 or 3:4 for portrait posters and 1:1 for social square posts
  4. Check the visual feature locking: hair gradient, whale-fin ears, cowlick, tail and uniform
  5. Credit the character IP as the README's attribution section asks

Prompt for your agent
