design-system

design-system is a skill for Claude Code, Codex from nextlevelbuilder/ui-ux-pro-max-skill. It costs 52 tokens per session (1,827 once invoked), scanned A, original, MIT.

A system for organizing design choices such as colors, spacing, text sizes, and component states into reusable named values. It also defines how interface components should be specified and how slides can be created consistently.

In plain words
What is it for?
Use it to create design tokens, CSS variables, component specifications, design-to-code guidance, Tailwind settings, and systematic presentations.
Why use it?
It keeps an interface or presentation consistent and makes shared design decisions easier to reuse and update.

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 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 yesterday.

The scan reads SKILL.md. This mod also ships 10 executable files (scripts/embed-tokens.cjs, scripts/fetch-background.py, scripts/generate-slide.py, …), 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.

Design System

Token architecture, component specifications, systematic design, slide generation.

When to Use

  • Design token creation
  • Component state definitions
  • CSS variable systems
  • Spacing/typography scales
  • Design-to-code handoff
  • Tailwind theme configuration
  • Slide/presentation generation

Token Architecture

Load: references/token-architecture.md

Three-Layer Structure

Primitive (raw values)
       ↓
Semantic (purpose aliases)
       ↓
Component (component-specific)

Example:

/* Primitive */
--color-blue-600: #2563EB;

/* Semantic */
--color-primary: var(--color-blue-600);

/* Component */
--button-bg: var(--color-primary);

Script Paths

Script paths in this skill and its references/ are relative to the directory that contains this SKILL.md, not to the project: scripts/<file> is this skill's own scripts/ folder, and ../<skill>/scripts/<file> is a sibling sub-skill installed alongside it. Build the full path from that directory (Claude Code reports it as the skill's base directory when the skill loads) and keep the working directory at the project root — the scripts read and write project files such as docs/brand-guidelines.md, assets/design-tokens.json or src/ relative to it.

Quick Start

Generate tokens:

node scripts/generate-tokens.cjs --config tokens.json -o tokens.css

Validate usage:

node scripts/validate-tokens.cjs --dir src/

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.
