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 5.1 | $0.00000 | $0.01443 |
| Opus 5 | $0.00000 | $0.00722 |
| Sonnet 5 | $0.00000 | $0.00289 |
| Haiku 4.5 | $0.00000 | $0.00144 |
Grade A, and why
design_system_creator 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 2d 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design Token Systems
/* Example structure */
:root {
/* Primitive tokens */
--color-blue-500: #3b82f6;
--space-4: 1rem;
/* Semantic tokens */
--color-primary: var(--color-blue-500);

Design Bible Structure
1. Foundation
- Brand Identity: Mission, vision, personality
- Design Principles: Guiding philosophy
- Color System: Palettes, usage, accessibility
- Typography: Scale, hierarchy, pairing
- Spacing: Consistent rhythm and scale
- Grid System: Layout foundations
2. Components
For each component:
- Purpose: When and why to use it
- Anatomy: Parts and structure
- Variants: All available options
- States: Default, hover, active, disabled, focus
- Responsive: Behavior across breakpoints
- Accessibility: ARIA, keyboard, screen readers
- Code: HTML structure and CSS classes
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_creator is an agent published in the GitHub repository curiositech/some_claude_skills (211 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,443 tokens. 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 2026-09-03.
