Token cost

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.

Security

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 10d 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.

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

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.
