RIPDPI: Skill for Claude Code

.agents/skills/material-3/SKILL.md

material-3 is a skill for Claude Code from po4yka/RIPDPI. It costs 53 tokens per session (4,679 once invoked), scanned A, original, BSD-3-Clause.

A reference and review guide for Material Design 3, Google's system of interface components, colours, shapes, typography, and motion. It covers the component vocabulary and checks whether implementations follow the system.

In plain words
What is it for?
Use it when implementing or auditing Material Design 3 components and design tokens in web, Flutter, or Compose projects.
Why use it?
It gives developers a shared language for building and reviewing consistent user interfaces.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is po4yka/RIPDPI's own configuration. It tells Claude Code how to work on RIPDPI itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything RIPDPI configures →

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-3 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 yesterday.

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

This skill guides implementation of Google's Material Design 3 (MD3) — a personal, adaptive, expressive design system. MD3 uses dynamic color, tonal surfaces, rounded shapes, and spring-based motion to create UIs that feel alive and personal.

RIPDPI note: this repo's Compose theme (RipDpiTheme) selects one of six generated Material 3 schemes (neutral seed #36414F, light and dark at three contrast levels that follow the system setting) and, only when the user turns on the opt-in Settings switch on Android 12+, the system dynamic scheme. Screens read colors, spacing, and typography through RipDpiThemeTokens (see the android-compose-patterns skill, DESIGN.md, and docs/design-system.md). Use this skill here for MD3 vocabulary, the component catalog, and the compliance-audit rubric. Call dynamicLightColorScheme/dynamicDarkColorScheme only inside RipDpiTheme; never in screens or components.

Philosophy

MD3 is built on three principles:

  • Personal: Dynamic color adapts UI to the user's wallpaper or content. Theming is individual, not one-size-fits-all.
  • Adaptive: Layouts transform across 5 window size classes. Components resize, reposition, and change form factor responsively.
  • Expressive: Shape morphing, spring physics, and emphasized typography create moments of delight without sacrificing usability.

Key differences from MD2:

  • Tonal surfaces replace elevation shadows as the primary depth cue
  • Dynamic color generates full schemes from a single seed color
  • Fully rounded corners by default (not slightly rounded)
  • Spring-based motion physics replace fixed easing curves for components
  • 3 levels of user-controlled contrast (standard/medium/high)

Relationship with frontend-design skill: When both skills are active, MD3 provides the design system (tokens, components, layout rules) and frontend-design provides creative direction within those constraints. MD3 rules take precedence for component structure and token usage. Note: Roboto/Roboto Flex IS the correct default typeface in MD3 — the frontend-design guidance to avoid Roboto does not apply when implementing MD3.

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.
