Compare agent skills before installing.

Use to establish the project's design canon — docs/design-system.md: the design-tool choice (Figma MCP / Pencil MCP / code-only markdown), the platform posture (mobile-first / desktop-first / responsive), the token source, and the reusable component inventory. Once per repo, like survey. Triggers on "set up the design system", "design canon", "which design tool", "establish the UI foundation", "/sdd:design-system", "налаштуй дизайн-систему", "дизайн-канон проєкту", "яким інструментом малюємо". Read by ux-flows (posture) and screens (tool + inventory); implement registers NEW components back into it. On tool: pencil it also bootstraps the .pen library itself — creates the file, walks the user through opening it, and seeds tokens + a foundations frame via the pen-keeper agent. Utility — not a backbone stage; run it before the first UI feature (ux-flows recommends it when absent).

Generate original one-ink or controlled two-ink editorial images from any theme, sentence, article idea, object, or reference photo. Always use this skill when the user asks for 单色海报、双色印刷、单色调视觉、蓝色/绿色孔版印刷、risograph、网点照片、复古或当代编辑排版、zine poster, monochrome editorial poster, duotone print, or asks to use the mono-color style. It uses an adaptive white, gray, or pale-beige substrate, no more than two printing inks, active negative space, terse human language, and strong serif/grotesk/mono typography without making retro styling the default or copying a source composition, wording, logo, or artwork. Produce both the final generation prompt and the generated raster image unless the user explicitly asks for prompt only.
