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.

What it costs to keep this loaded
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 | $0.00031 | $0.01524 |
| Opus 5.5 | $0.00012 | $0.00610 |
| Sonnet 5.5 | $0.00006 | $0.00305 |
| Haiku 4.5 | $0.00003 | $0.00152 |
Grade A, and why
material-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 2mo 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 — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Material Design 3 (Material You)
Apply Google's Material Design 3 principles when designing and developing user interfaces with emphasis on personalization, accessibility, and cross-platform consistency.
Anti-fabrication
This skill follows core:anti-fabrication. The claim area is the tonal-palette, type-
scale, and layout-breakpoint numbers, which come from a living spec rather than a
versioned release. Verified against m3.material.io plus the first-party
material-color-utilities source (claude-skills-223), three corrections: tonal palettes
have 13 tones (0,10,20...90,95,99,100 per commonTones), not "50-99 tones per color";
the type scale is 5 categories x 3 sizes = 15 styles total, not "5 display sizes and 9
text sizes" (the sp values 57/32/16/11 were already correct); and MD3 now defines 5
window-size classes, not 3 — Expanded is capped at 1199dp, with Large and Extra-large
added above it. Re-verify against m3.material.io before asserting a token count or
breakpoint this skill doesn't cover — Google updates this spec continuously, with no
versioned release to pin against.
What is Material Design 3?
Material Design 3 (Material You) represents Google's latest design system with:
- Personalization: Dynamic color extraction from user preferences
- Expressiveness: Softer, rounded components with visual hierarchy
- Adaptability: Responsive across devices and platforms
- Accessibility: Built-in inclusive design features
Key Differences from Material Design 2
| Aspect | MD2 | MD3 |
|---|---|---|
| Colors | Fixed brand palettes | Dynamic, user-generated schemes |
| Customization | Limited theming | Highly personalized |
| Components | Flat, rigid shapes | Rounded, expressive |
| Accessibility | Basic support | Priority built-in |
Core Foundations
1. Dynamic Color System
Material Design 3 uses HCT (Hue, Chroma, Tone) color space for perceptually accurate color generation.
Key concepts:
- Color roles (primary, secondary, tertiary, error, neutral)
- Tonal palettes (13 tones per color: 0, 10, 20...90, 95, 99, 100 — per material-color-utilities'
commonTones) - Automatic light/dark theme generation
- User-driven personalization from wallpaper/system
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.

material-design is a skill published in the GitHub repository vinnie357/claude-skills (27 stars, last pushed 14d ago), licensed MIT. It adds 31 tokens to every session and 1,524 once invoked, about $0.0001 per session on Opus 5.5. 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.
