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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00036 | $0.04095 |
| Opus 5 | $0.00018 | $0.02048 |
| Sonnet 5 | $0.00007 | $0.00819 |
| Haiku 4.5 | $0.00004 | $0.00409 |
Grade A, and why
design-system-starter 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 604 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design System Starter
Build robust, scalable design systems that ensure visual consistency and exceptional user experiences.
Quick Start
Just describe what you need:
Create a design system for my React app with dark mode support
That's it. The skill provides tokens, components, and accessibility guidelines.
Triggers
| Trigger | Example |
|---|---|
| Create design system | "Create a design system for my app" |
| Design tokens | "Set up design tokens for colors and spacing" |
| Component architecture | "Design component structure using atomic design" |
| Accessibility | "Ensure WCAG 2.1 compliance for my components" |
| Dark mode | "Implement theming with dark mode support" |
Quick Reference
| Task | Output |
|---|---|
| Design tokens | Color, typography, spacing, shadows JSON |
| Component structure | Atomic design hierarchy (atoms, molecules, organisms) |
| Theming | CSS variables or ThemeProvider setup |
| Accessibility | WCAG 2.1 AA compliant patterns |
| Documentation | Component docs with props, examples, a11y notes |

Design System Philosophy
What is a Design System?
A design system is more than a component library—it's a collection of:
- Design Tokens: Foundational design decisions (colors, spacing, typography)
- Components: Reusable UI building blocks
- Patterns: Common UX solutions and compositions
- Guidelines: Rules, principles, and best practices
- Documentation: How to use everything effectively
Core Principles
1. Consistency Over Creativity
- Predictable patterns reduce cognitive load
- Users learn once, apply everywhere
- Designers and developers speak the same language
What ships with it
5 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.
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-starter is a skill published in the GitHub repository softaworks/agent-toolkit (2,418 stars, last pushed 6mo ago), licensed MIT. It adds 36 tokens to every session and 4,095 once invoked, about $0.0002 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 2026-08-30.
Other skills, from other repositories
feishu
Work with Feishu or Lark bots, docs, sheets, bitables, approval flows, and OpenAPI/MCP setup without hardcoding credentials.
interview
Ask one useful structured question at a time only when material product/implementation choices are genuinely missing; remember answers and produce a brief/spec. Discoverable facts should be investigated instead of asked.
writing
将共享历史中的已验证事实和计算结果整理成符合受众、格式与长度约束的成稿。.
test
Detect the project’s test stack, run the narrowest useful tests, create tests when authorized, and report coverage/gaps honestly.
verify
Exercise the real app/API/CLI and collect observable evidence; tests alone do not count as end-to-end verification.
ccc
This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the…
