What is design-system?

A guide for creating a design system: a shared set of rules for colours, fonts, interface components, and user experience. It can gather brand and interface requirements, generate colour palettes, and produce documentation.

Use it to document brand guidelines, define colour and typography rules, create component style guides, and generate palette output as Markdown, Tailwind settings, or CSS variables.

It helps keep an interface consistent across pages and devices. It also reduces the need to decide colours, typography, and component styles separately each time.

design-system — Skill for Claude Code by rungchan2

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add rungchan2/frontend-skills --skill design-system

Clone the repo

git clone --depth 1 https://github.com/rungchan2/frontend-skills

Made for: Claude Code.

Or install spec-generator, the plugin that ships this one along with the rest of its 4 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00082	$0.02495
Opus 5	$0.00041	$0.01247
Sonnet 5	$0.00016	$0.00499
Haiku 4.5	$0.00008	$0.00249

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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate_palette.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.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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 rungchan2/frontend-skills (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 82 tokens to every session and 2,495 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
