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-skills CLAUDE.md 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 2mo 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.

Project Overview

This is a Claude Code plugin marketplace for design system development. It provides skills (markdown-based prompt templates) that guide Claude through generating design tokens, components, and accessibility patterns.

Skill File Format

Each skill is a SKILL.md file with YAML frontmatter:

---
name: skill-name
description: Use when [trigger conditions]. Supports [output formats].
---

# Skill Name

## Overview
[What it does - 1-2 sentences]

## When to Use
[Bullet list of scenarios]

## Quick Reference
[Tables with key information]

## The Process
[Numbered steps Claude follows]

## Output Formats
[Code examples for CSS, Tailwind, JSON]

Token Skills Patterns

All token skills share these conventions:

  • Output formats: CSS custom properties, Tailwind config, JSON tokens
  • Naming: T-shirt sizes (xs, sm, md, lg) or numeric (100, 200, 300)
  • Process: Gather input → ask format → generate → output

Color scale uses OKLCH by default (perceptually uniform). Spacing/type use ratio-based exponential scales.

Adding New Skills

  1. Create directory under appropriate category: skills/{category}/{skill-name}/
  2. Add SKILL.md following the format above
  3. Update README.md to list the new skill
  4. Skills are auto-discovered by Claude Code from the skills/ directory

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.
