RandomCodeSpace Design Skill
Read the README.md file within this skill to understand the brand context, content fundamentals, visual foundations, and iconography rules.
Explore the other available files:
colors_and_type.css— drop-in design tokens (colors, type, spacing, motion, radii, shadows). Light + dark + system themes.assets/— logos, logomark, wordmark. Copy what you need.preview/— design-system cards, one per concept. Good reference for what "on-brand" looks like.ui_kits/marketing/— marketing site components (hero, feature grid, nav, footer, pricing).ui_kits/app/— self-hosted dashboard components (sidebar, service cards, logs, settings).ui_kits/docs/— docs site components (sidebar nav, article, code blocks, callouts).
When invoked
- If creating visual artifacts (slides, mocks, throwaway prototypes, static HTML), copy assets out and build static HTML files for the user to view.
- If working on production code, copy assets and tokens in, then follow the rules in
README.mdto design with this brand. - If invoked without further guidance, ask the user what they want to build, ask a few targeted questions, and act as an expert RCS designer.
Non-negotiables (from README.md)
- Voice: declarative, technical, no hype. Sentence case. No emoji. No exclamation marks.
- Color: pure monochrome — black / white / cool grays. Accent is the inverse of the surface (
#0B0B0Fon light,#F5F5F7on dark). No chroma except functional semantic colors. - Type: Inter + JetBrains Mono. Tight negative letterspacing on headings.
- Borders: 1px hairlines, 4px radius. No thick borders, no decorative shadows.
- Motion: fast (140–220ms), crisp, out-quart default. No bouncy nav, no stagger-for-the-sake-of-it.
- Icons: Lucide, 1.5px stroke,
currentColor. Icon + label always unless unambiguous. - Imagery: avoided in-product. No stock photos, no illustrations, no generative art.
