When someone asks you to make a poster or visual piece, this generates actual design artifacts instead of giving you layout suggestions. It works in two phases: first Claude writes a design philosophy document (think "Brutalist Joy" or "Chromatic Silence") as a creative movement with specific visual principles, then uses that philosophy to create a PNG or PDF that's 90% visual, 10% text. The philosophy emphasizes things like color theory, spatial relationships, and composition while stressing that the output should look meticulously crafted, not thrown together. It's built for making art objects and posters, not decorated documents with paragraphs of text.
