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 | $0.00265 | $0.00265 |
| Opus 5 | $0.00133 | $0.00133 |
| Sonnet 5 | $0.00053 | $0.00053 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
design-system CLAUDE.md 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 5d 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.
What it actually says
Design System Toolkit
Give Claude a brand or site reference → get back a full design system reference page AND a 1-page A4 brand book PDF.
What this toolkit does
- Extracts colors, fonts, principles from any reference you provide (URL, screenshot, existing site, or description)
- Generates
design/design-system.html— a scrollable reference page - Generates
design/brand-book-a4.html— a single A4 portrait page - Renders
design/brand-book-a4.pdfvia headless Edge/Chrome
The skill is at .claude/skills/design-system/SKILL.md. Read it first, then follow the workflow there.
Rules
- Extract from the reference first. Don't ask the user what you can see yourself.
- Never invent brand details. Colors, fonts, names, taglines come from the user or the reference.
- Never redraw logos. Use the exact SVG the user provides.
- Template bends to the brand. Dark is the default, but match the reference if it differs.
- Fit on one A4 page. If content overflows, tighten or drop a section.
- Render the PDF. Don't hand over HTML without the rendered output.
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 CLAUDE.md is an instructions file published in the GitHub repository robonuggets/design-system (126 stars, last pushed 4mo ago), licensed MIT. It adds 265 tokens to every session, about $0.0013 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.
