A set of standards and review steps for designing, building, and auditing user interfaces. It covers design tokens, reusable components, visual details, motion, and common signs of AI-generated design.

Use it when creating, reviewing, redesigning, or auditing a web interface, including Tailwind or React projects.

It helps keep interfaces consistent and catches visual or interaction problems through a static review and a browser-based check.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00192	$0.02960
Opus 5	$0.00096	$0.01480
Sonnet 5	$0.00038	$0.00592
Haiku 4.5	$0.00019	$0.00296

Measured 12d ago against content hash d9931a97d1b9, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

craft-ux 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (references/scanner-fixtures/cross-layer.tokens.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UX Craft

The single, self-contained standard for building UI with consistency and intention — applied the same way across every repo. The method and opinions live here; the project specifics (token names, component paths, framework) live in the target repo and are always discovered, never hardcoded. Illustrated stack: Tailwind + React are the primary examples in references; layering principles (tokens → primitives → components → states → motion) apply regardless — do not invent large Vue/Svelte-specific docs when the project uses another UI stack; map principles to what discovery finds.

Standards, patterns, motion frameworks, and review protocols live in references/ and load on demand. Before any non-trivial task, read references/foundations.md — it defines the persona, operating principles, the discover-before-build discipline, standing opinions, hard constraints, and communication style that everything else assumes.

Supersedes the older split skills: elite-ux-architect, ux-architect, review-ux, design-motion-principles, redesign-existing-projects.

Initialization

When invoked without a specific task: introduce capabilities briefly, ask for direction. Do not proactively audit, scan files, or assess implementation quality. Wait for the user.

The design-system layers (build in this order)

The spine of the skill. Each layer builds on the one below; get the lower layers right before reaching for the higher ones. For the meta-guide on how to stand up (or harden) the whole system — the layered architecture, the CSS-variable bridge, governance, and migration order — read references/building-a-design-system.md. To keep it from rotting, references/token-audit.md covers finding violations and building the scanner that blocks them in CI.

Tokens — color, spacing, typography as CSS variables + a typed module. → references/layer-1-tokens.md
Primitives & implementation — Stack/Inline/Grid/Box and the Tailwind/cn()/CVA mechanics every component sits on. → references/layer-2-primitives.md
Components — the supported set (forms, tables, modals, nav, notifications) with consistent variant/size APIs. → references/layer-3-components.md
States — loading, empty, error, disabled as first-class. → references/layer-4-states.md
Motion & accessibility — purposeful motion + the a11y floor. → references/layer-5-motion.md (three designer deep-dives live in references/motion/ — Emil, Jakub, Jhey)

What ships with it

24 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.

craft-ux is a skill published in the GitHub repository gul-labs/craftsman-marketplace (1 stars, last pushed today), licensed MIT. It adds 192 tokens to every session and 2,960 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
