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 | $0.00044 | $0.00293 |
| Opus 5 | $0.00022 | $0.00147 |
| Sonnet 5 | $0.00009 | $0.00059 |
| Haiku 4.5 | $0.00004 | $0.00029 |
Grade A, and why
frontend-design-systems 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 7d 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
Frontend Design Systems & UI Architecture
Attribution: Originating from Anthropic & the skills.sh open ecosystem. Maintained in canonical SKILL.md format.
This skill guides the construction of modern, accessible, responsive frontend applications utilizing design tokens, component primitives, and Tailwind CSS.
Key Guidelines
- Token Hierarchy: Separate global design tokens (colors, spacing, typography) from component-specific styles.
- Accessible Primitives: Use headless accessible primitives (Radix UI, React Aria) for complex interactions like dialogs, dropdowns, and comboboxes.
- Responsive by Default: Mobile-first breakpoints (
sm,md,lg,xl) with dark mode class strategy (class="dark").
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.

frontend-design-systems is a skill published in the GitHub repository pedroiff0/awesome-skills (1 stars, last pushed 4d ago), licensed MIT. It adds 44 tokens to every session and 293 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 2026-09-03.
