Design & UX

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.

Review a PR or the current branch for a Lumen design-system change — routes each changed file to React (web/Tailwind) or React Native (useStyleSheet) guidelines, checks the Nx version plan, and reports a flat, severity-scored finding list. Use when the user asks to review a PR, review code changes, check a branch, do a local code review, or provides a GitHub PR URL.

Use when implementing or updating a component from a Figma link — how to turn the Figma design variables into code tokens, on both platforms: Tailwind classnames for libs/ui-react and themeJS (`t.*`) paths for libs/ui-rnative. For the full token catalogues and styling mechanics, see component-styling.

Use when building or styling a component in libs/ui-react or libs/ui-rnative (and their visualization libs) — the cross-platform styling principles, plus routing to the platform mechanics: Tailwind + cva + cn on web, useStyleSheet + themeJS + lx on React Native. Load this before writing component styles.

Use when writing or editing Storybook MDX docs (*.mdx) — the two-tab Overview/Implementation structure, story-backed `<Source>` examples, and doc table guidelines.

Creates and maintains Figma Code Connect files (`*.figma.tsx`) that map Figma components to code via the parser-based `figma.connect()` API. Use when the user mentions Code Connect, Figma component mapping, design-to-code translation, or asks to create/update .figma.tsx files.

Review UI designs and implementations for accessibility, consistency, usability, and visual quality. Use when asked to review a design, audit accessibility, check UI consistency, compare implementation against mockups, or evaluate a user interface.

Manage design work in Penpot — create projects, organize pages, build components, export assets, review designs visually, and handle design-to-code handoff. Use when asked to create designs, manage Penpot projects, build components, export tokens, set up a new design project, review a design, take screenshots, or show what something looks like.

Reverse-engineer a design system from a live website (public URL or localhost). Extracts colors, typography, spacing, shadows, radii, breakpoints, and component patterns using a headed Playwright browser. Captures screenshots of pages, components, and interactive states at real device resolutions. Produces structured design tokens and optionally seeds a Penpot project. **Triggers — use this skill when:** - User says "extract design system from [url]" - User asks to "reverse-engineer the styl...

Build, maintain, and audit design systems — tokens, component libraries, style guides, and cross-project consistency. Use when asked to create a design system, define tokens, audit component consistency, generate a style guide, or sync design tokens with code.

Generate low-fidelity wireframes (ASCII, SVG, or HTML) from user story files. Use when creating wireframes for UI stories.

Produce a coherent visual identity (palette, typography, spacing, radius) from a brief and serialise to JSON for the design-tokens skill. Use when establishing brand identity.

Scaffold high-fidelity UI component mockups using the project UI stack consuming approved wireframes. Use when implementing approved wireframes.

Read and write design tokens in W3C DTCG format (tokens.json) and emit CSS, Tailwind, and Mantine outputs. Use when modifying or generating design tokens.

Run WCAG 2.2 Level AA accessibility audits against generated UI. Use when a story has ui:true or when asked to audit accessibility.
