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 | $0.00046 | $0.04124 |
| Opus 5 | $0.00023 | $0.02062 |
| Sonnet 5 | $0.00009 | $0.00825 |
| Haiku 4.5 | $0.00005 | $0.00412 |
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 11d 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 Starter
Overview
This skill provides comprehensive guidance for building robust, scalable design systems that ensure visual consistency, improve development velocity, and create exceptional user experiences. Whether starting from scratch or evolving an existing system, this framework helps teams design with intention and scale.
When to use this skill:
- Creating a new design system from scratch
- Evolving or refactoring existing design systems
- Establishing design token standards
- Defining component architecture
- Creating design documentation
- Ensuring accessibility compliance (WCAG 2.1)
- Implementing theming and dark mode

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
2. Accessible by Default
- WCAG 2.1 Level AA compliance minimum
- Keyboard navigation built-in
- Screen reader support from the start
3. Scalable and Maintainable
- Design tokens enable global changes
- Component composition reduces duplication
- Versioning and deprecation strategies
4. Developer-Friendly
- Clear API contracts
- Comprehensive documentation
- Easy to integrate and customize
Design Tokens
What ships with it
4 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 ArieGoldkin/ai-agent-hub (11 stars, last pushed 9mo ago), licensed MIT. It adds 46 tokens to every session and 4,124 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.
