vanehub-ai: Skill for Claude Code

.claude/skills/design-system/SKILL.md

design-system is a skill for Claude Code from cdavid817/vanehub-ai. It costs 52 tokens per session (1,693 once invoked), scanned A, a copy of design-system, Apache-2.0.

A design-system toolkit for defining shared design values, such as colors, spacing, and text sizes, and describing reusable interface components.

In plain words
What is it for?
Use it to create CSS variables, component specifications, design-to-code handoffs, Tailwind themes, and structured presentation slides.
Why use it?
It helps keep screens and components visually consistent instead of choosing styles separately each time.

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 9d ago.

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.

Origin

This is a copy

100% identical to design-system — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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);

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.
