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.

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 | $0.00139 | $0.02727 |
| Opus 5.5 | $0.00056 | $0.01091 |
| Sonnet 5.5 | $0.00028 | $0.00545 |
| Haiku 4.5 | $0.00014 | $0.00273 |
Grade A, and why
design-system-generator 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.

Design System Generator / 设计系统生成器
Generate a complete, production-ready design system from minimal brand inputs. 从最少的品牌输入自动生成完整的、可投产的设计系统。
Core Principles / 核心原则
- One Color In → Full System Out: The user only needs to provide a single brand color. Everything else is derived algorithmically.
- OKLCH-First: All colors are generated in the OKLCH color space for perceptual uniformity and superior accessibility.
- W3C Standards: Output follows the W3C Design Tokens specification (
$value/$typeformat). - Zero Dependencies: Generated CSS uses only native custom properties — no preprocessors, no frameworks required.
- Accessibility by Default: All color combinations meet WCAG 2.2 AA contrast ratios (4.5:1 for text, 3:1 for UI elements).
- Progressive Enhancement: Dark mode uses
color-scheme+light-dark()for native OS integration.
Workflow / 工作流
You MUST follow these phases in order. Do NOT skip phases or generate all files at once without user confirmation at each stage.
你必须按顺序执行以下阶段。不要跳过阶段，也不要在未获得用户确认的情况下一次性生成所有文件。
Phase 1: Brand Input Collection / 品牌输入收集
Trigger / 触发: User asks to create a design system, generate a theme, or build brand styles.
Your Task / 你的任务: Collect brand parameters through conversation. At minimum, you need ONE of these:
| Parameter | Required | Default | Example |
|---|---|---|---|
| Brand color | ✅ Yes | — | #6366f1, oklch(55% 0.25 270), indigo |
| Font family | Optional | Inter, system-ui, sans-serif |
"Outfit", "Noto Sans SC" |
| Border radius style | Optional | rounded (8px) |
sharp (2px), rounded (8px), pill (9999px) |
| Density | Optional | comfortable |
compact, comfortable, spacious |
Steps:
- If user gives a color name (e.g., "blue", "coral"), convert it to a hex value first.
- Convert any hex/rgb color to OKLCH using the algorithm in color-system.md.
- Present a summary of all parameters to the user and ask for confirmation.
- If the user says "just use defaults" or gives only a color, proceed with defaults for all optional fields.

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-generator is a skill published in the GitHub repository XINGANLIU/design-system-generator-skill (1 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 139 tokens to every session and 2,727 once invoked, about $0.0006 per session on Opus 5.5. 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.
