design-system

design-system is a skill for Claude Code, Codex from sso-ss/vibe-ship-it. It costs 63 tokens per session (1,220 once invoked), scanned B, original, MIT.

A method for turning an app's existing visual style into reusable design rules and interface pieces. These rules cover things such as colors, text sizes, spacing, shapes, shadows, and motion.

In plain words
What is it for?
Use it to set up a design system, standardize an app's appearance, extract style tokens, and create reusable basic interface components.
Why use it?
It reduces mismatched styles and repeated manual decisions across pages. Existing designs can be made reusable without changing how they look.

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 B, and why

design-system scanned grade B with 1 finding 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 10d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

Do not lecture about rules. Just follow them silently when building new pages.

How it starts

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design System

Makes your app look consistent everywhere. Pulls the visual style from what you already built and turns it into reusable pieces.

How It Works

One pass. Not a multi-step project.

  1. Scan existing pages for repeated visual patterns
  2. Extract them into named tokens (colors, sizes, spacing, shapes, shadows)
  3. Generate primitive components wired to those tokens
  4. Apply them in place so nothing looks different yet, but everything is now reusable
  5. Show the result

If no pages exist yet, start from smart defaults that look like a real product.

When To Use

  • "Set up a design system"
  • "Make styles consistent"
  • "Make it all match"
  • "Set up tokens"
  • "Create components from my styles"
  • "Standardize this"

Starting Point

If DESIGN.md exists

Use it as the source of truth. Extract tokens directly from the DESIGN.md file -- colors, type scale, spacing, radii, shadows, motion. Map them to the token names below and generate primitives wired to those values. Do not re-extract from the existing UI. DESIGN.md wins.

Token mapping from DESIGN.md: DESIGN.md uses richer names than the token table below. Map them: text-primarytext, text-secondary/text-tertiarymuted, surface → use as card/panel background, accent-hover → generate hover variant of accent, border-subtle → lighter shade of border. Drop accent-gradient into button/CTA styles directly. Ignore any DESIGN.md tokens not listed below -- they are implementation hints, not system tokens.

If pages already exist (no DESIGN.md)

Extract tokens from the current UI. Preserve the existing look. The system should formalize what's already there, not redesign it.

If no pages exist yet (no DESIGN.md)

Generate a neutral, modern token set with good defaults:

  • Clean type scale, comfortable spacing, subtle shadows, accessible contrast
  • Feels like a real product out of the box

Use Material Design 3 as the internal reference for token categories, component patterns, and accessibility defaults. Never mention "Material" to the user. They just get a clean, modern system.

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.

design-system is a skill published in the GitHub repository sso-ss/vibe-ship-it (12 stars, last pushed 5mo ago), licensed MIT. It adds 63 tokens to every session and 1,220 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (strips warnings and disclaimers). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
