styleguide skillA

styleguide is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: Create a comprehensive design language and styleguide for any project — websites, apps, blogs, presentations, marketing pages. Given a project type, brand, and audience, produces aesthetic direction, font selections with pairings, color strategy, spacing philosophy, imagery style, and tone. Use when the user asks to "create a styleguide", "define the design language", "what fonts should I use", "choose a color palette for my project", "design direction for my website", "how should my app look", .
