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 | $0.00122 | $0.07010 |
| Opus 5 | $0.00061 | $0.03505 |
| Sonnet 5 | $0.00024 | $0.01402 |
| Haiku 4.5 | $0.00012 | $0.00701 |
Grade A, and why
modern-web-design 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.
This is a copy
100% identical to modern-web-design — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Modern Web Design
Overview
Modern web design in 2024-2025 emphasizes performance, accessibility, and meaningful interactions. This skill provides comprehensive guidance on current design trends, implementation patterns, and best practices for creating engaging, accessible, and performant web experiences.
This meta-skill synthesizes knowledge from all animation, interaction, and 3D skills in this repository to provide holistic design guidance.
Core Design Principles (2024-2025)
1. Performance-First Design
Philosophy: Design decisions should prioritize Core Web Vitals and user experience on all devices.
Key Metrics:
- Largest Contentful Paint (LCP): < 2.5s
- First Input Delay (FID): < 100ms
- Cumulative Layout Shift (CLS): < 0.1
- Interaction to Next Paint (INP): < 200ms
Implementation Guidelines:
- Defer non-critical animations until after page load
- Use CSS transforms/opacity for animations (GPU-accelerated)
- Implement lazy loading for images, videos, and 3D content
- Progressive enhancement: core content without JavaScript

2. Bold Minimalism
Characteristics:
- Large, impactful typography (clamp() for fluid sizing)
- Ample white space (negative space as design element)
- Limited color palettes (3-5 primary colors)
- Intentional use of bold accent colors
- Geometric shapes and clean lines
Typography Scale (Modern fluid system):
/* Fluid typography using clamp() */
--font-size-xs: clamp(0.75rem, 0.7rem + 0.25vw, 0.875rem);
--font-size-sm: clamp(0.875rem, 0.8rem + 0.375vw, 1rem);
--font-size-base: clamp(1rem, 0.9rem + 0.5vw, 1.25rem);
--font-size-lg: clamp(1.25rem, 1.1rem + 0.75vw, 1.75rem);
--font-size-xl: clamp(1.75rem, 1.5rem + 1.25vw, 2.5rem);
--font-size-2xl: clamp(2.5rem, 2rem + 2.5vw, 4rem);
--font-size-3xl: clamp(3.5rem, 2.5rem + 5vw, 6rem);
Color System (Accessibility-first):
/* WCAG AAA compliant color system */
--color-primary: oklch(50% 0.2 250); /* Blue */
--color-accent: oklch(65% 0.25 30); /* Coral */
--color-neutral-50: oklch(98% 0 0);
--color-neutral-900: oklch(20% 0 0);
/* Contrast ratio: minimum 7:1 for text */
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.
- 7d ago First seen · 991 lines · 122 tokens per session scan A 062b0120b590
modern-web-design is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (29 stars, last pushed yesterday), licensed MIT. It adds 122 tokens to every session and 7,010 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to modern-web-design, differing in 0 lines, and is treated as a copy.
