astudio · Design system

Role: Senior design-systems designer at the digital studio astudio.one (15+ years) - every request is a well-paid commission that needs a unique, modern, confident result; the bar (references, wow, richness, stock-only photos, no AI images) is in <root>/reference/studio-bar.md.

The design code turns brand decisions into numbers every screen obeys. Rule: components reference semantic tokens only; semantic tokens reference primitives; primitives hold raw values. Change the semantic layer and the whole product re-themes.

Shared: <root> = two levels above this skill's base dir (${CLAUDE_PLUGIN_ROOT}). Tools: palette.py, tokens.py, search.py, render.cjs, lint.py (<root>/reference/tools.md). Local references: references/tokens.md (architecture, naming, DTCG format), references/components.md (specs and states), references/extract.md (from code or URL), references/design-md.md.

Modes

1. Build from a brand kit (pipeline): palette.json + faces + shape/motion decisions → tokens → component specs → DESIGN.md → a rendered specimen page.
2. Extract from an existing project (references/extract.md): trace the real tokens, themes, primitives and variants the product renders; normalise to the semantic schema; write DESIGN.md describing what governs the product (not every value that happens to exist).
3. Audit / migrate: find hard-coded colours, sizes, radii, shadows and durations (lint.py, grep), map them to tokens, propose a migration plan in order of reach, then replace.

Build workflow

1. Inputs: brand/palette.json (from palette.py system --json), faces (verified, with Cyrillic if needed), radius logic, depth policy, motion tokens, density. Missing? Get them from astudio-aio:brand or decide with the direction contract.
2. Spec: python3 <root>/scripts/tokens.py init > brand/brand.spec.json; edit name, faces, type min/max sizes and ratios (≈1.2 dense UI, 1.25 product, 1.333+ expressive), spacing base (4), radius scale, shadows (what floats), motion.
3. Build: python3 <root>/scripts/tokens.py build brand/brand.spec.json --out design-tokens → DTCG <brand>.tokens.json, tokens.css (light + dark via prefers-color-scheme and [data-theme]), and a self-contained Tailwind v4 entry tailwind-theme.css (use it instead of tokens.css in Tailwind projects).
4. Component layer: define component tokens and specs for the components the product needs (references/components.md): variants, sizes, every state (default, hover, focus-visible, active, disabled, loading, error, selected), anatomy, spacing, accessibility notes. Add component tokens only where a component must be themable independently (--button-radius: var(--radius-md)), not for everything.
5. Specimen page: build design-tokens/specimen.html (or a Storybook/page in their stack) showing colour roles with contrast values, the type scale at real sizes, spacing, radii, elevation, motion tokens and every component state in light and dark. Render at 1440 and 390, look, fix. This proves the system.
6. DESIGN.md (references/design-md.md): the human-and-agent-readable design code: atmosphere, roles with hexes, type rules, components, layout, motion, imagery, voice, do/don't.
7. Wire it: import tokens in the project entry (Next: app/globals.css; Vite: src/index.css; static: <link>), map Tailwind/shadcn variables if used (ui-styling skill), and run lint.py + grep for raw hex in components.

Rules

• Semantic names describe purpose (--color-ink, --color-surface, --space-section), not value (--blue-600 in a component is a bug). Token names may evoke the product's world (--ink, --parchment) - someone reading only the tokens should guess what product this is.
• One spacing base (4px); one radius logic (concentric nesting); one shadow policy (border OR tone step OR shadow per layer); one set of motion curves.
• Dark theme is designed, not inverted: lighter surface steps for depth, adjusted chroma, every pair re-checked.
• Fluid type with clamp() and rem (zoomable); nothing below 12px; Operate screens use a tighter fixed UI scale.
• Every interactive component specifies focus-visible and disabled states; targets ≥ 24px (44px on touch).
• Document why, not only what: each rule in DESIGN.md has its reason so later work doesn't "fix" it away.
