A usage guide for the Acme UI component library, a collection of ready-made interface parts for React and Next.js web applications. It explains stylesheet imports, component imports, Tailwind design tokens, and reference areas for accessibility, performance, and security.

Use it when adding Acme UI buttons, cards, styles, design tokens, or related React and Next.js interface code.

It gives developers the approved paths and conventions for using the library instead of guessing how components and visual styles should be connected.

acme-ui — Skill for Claude Code and Codex by vercel-labs

About the project

DS Skills Pipeline is a command-line workflow that turns a design system's source code into structured skills for coding agents. It extracts verified tokens, components, icons, assets, usage patterns, and import paths, then generates and verifies reference files that agents can use when working with the design system.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add vercel-labs/design-systems-to-agent-skills --skill acme-ui

Clone the repo

git clone --depth 1 https://github.com/vercel-labs/design-systems-to-agent-skills

Made for: Claude Code, Codex.

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	$0.00000	$0.00422
Opus 5	$0.00000	$0.00211
Sonnet 5	$0.00000	$0.00084
Haiku 4.5	$0.00000	$0.00042

Measured 12d ago against content hash 6aae6df5c7b3, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

acme-ui 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.

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.

What it actually says

Acme UI Design System Skill

Package: @acme/ui v1.0.0 Framework: React 18 + Next.js 14 (App Router)

Quick Start

Import the stylesheet in your root layout:
```
import '@acme/ui/styles.css'
```

Import components from subpaths:

import { Button } from '@acme/ui/components/button'
import { Card } from '@acme/ui/components/card'

Use design tokens via Tailwind @theme inline:

@theme inline {
  --color-acme-blue-600: var(--acme-blue-600);
  --color-acme-gray-100: var(--acme-gray-100);
  --spacing-acme-4: var(--acme-space-4);
}

Then use as Tailwind utilities: bg-acme-blue-600, p-acme-4.

Files

What ships with it

11 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.

acme-ui is a skill published in the GitHub repository vercel-labs/design-systems-to-agent-skills (37 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 422 tokens. 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 2026-08-30.
