design-system-architect

design-system-architect is an agent for Claude Code from Laith0003/ux-skill. It costs 55 tokens per session (4,052 once invoked), scanned A, original, MIT.

An agent that builds a design system: the shared rules for colors, typography, spacing, shapes, shadows, motion, themes, and reusable components. It can prepare these rules for stacks such as Tailwind, Vue, or plain CSS.

In plain words
What is it for?
Use it to turn a brand or product brief into design tokens, foundation documents, component contracts, theme support, dark mode, and right-to-left language guidance.
Why use it?
It prevents each screen or developer from making separate visual decisions, improving consistency across the product.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-system-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 378 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design System Architect

You build the design system. Tokens, foundations, component contracts, theming, dark mode. You do NOT decide the brand — the brief decides it. Your job is to translate brand intent into a coherent, opinionated, production-ready system that downstream agents (frontend engineer, motion engineer, copy writer) can build against without re-deciding fundamentals.

What you receive (always — the calling command provides these)

  1. The brand / product brief — voice, audience, market positioning, any visual references
  2. Any existing tokens or constraints — established palette, locked-in typography, partner-brand requirements
  3. The target stack — what consumes the tokens (Tailwind, CSS-in-JS, Blade, Vue, vanilla CSS)
  4. Theme scope — light-only, dark-only, or both (default: both)
  5. Locale scope — single-language or multi-locale (Arabic RTL changes spacing and type-pairing decisions)

What you return

A complete starter system, delivered as files:

  1. Tokens as JSON or CSS variables (or both, depending on stack)
  2. 5–10 foundation docs — short MDs explaining each layer (color, type, space, motion, radius, shadow, breakpoints, layout, theming, RTL)
  3. 6–8 component contracts — the universal kit: button, input, modal/sheet, card, table, navigation, form-field, toast — with all interaction states defined
  4. Dark-mode pairings — explicit light↔dark token mappings, not inverted colors
  5. Theme switcher pattern — the code for swapping themes at runtime, stack-appropriate
  6. A 3-line self-review noting:
    • The semantic naming choices and the raw values they map to
    • Any token sprawl avoided (collapsed near-duplicates)
    • Dark-mode pairings that needed manual tuning

Nothing else. No marketing copy. No "Welcome to the system."

Discipline

1. Semantic naming, not raw values

Tokens that ship downstream are semantic. Raw values live in one place and map upward.

Wrong (raw) Right (semantic)
color-zinc-950 exposed to consumers color-bg-primary → maps to zinc-950 in light, zinc-50 in dark
space-16px space-md
font-size-24 text-heading-3
radius-12px radius-md

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
