design-language

design-language is a skill for Claude Code from nikzlabs/shipit. It costs 41 tokens per session (2,515 once invoked), scanned A, original, Apache-2.0.

A guide to ShipIt’s visual system, including colors, fonts, icons, animation, and light and dark themes. It explains how shared design tokens keep these choices consistent across the interface.

In plain words
What is it for?
Use it when styling UI components, adding themes, changing color or typography tokens, or implementing visual states and motion.
Why use it?
It helps developers add or change visual elements without breaking theme support or introducing inconsistent styling.

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-language 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 5d 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.

Design Language

ShipIt uses semantic design tokens (CSS custom properties) for all colors. Themes are token overrides applied via a class on <html>. All UI code references tokens — never raw Tailwind color classes.

Concrete color values live in per-theme CSS files under src/client/themes/. Each file defines one theme's token values. src/client/index.css imports them and contains shared rules (animations, scrollbars, syntax highlighting). Theme state is managed by useTheme() in src/client/hooks/useTheme.ts (persisted to localStorage key shipit-theme).

src/client/themes/
  light.css       ← :root { --color-bg-primary: ...; }
  dark.css        ← .dark { --color-bg-primary: ...; }

To add a new theme: create a new CSS file in themes/, import it in index.css, register the name in useTheme(). No component changes needed.

Color Tokens

Never use raw Tailwind color classes like bg-gray-950 or text-blue-500 in components — use bg-[var(--color-bg-primary)].

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.
