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 | $0.00071 | $0.06326 |
| Opus 5 | $0.00036 | $0.03163 |
| Sonnet 5 | $0.00014 | $0.01265 |
| Haiku 4.5 | $0.00007 | $0.00633 |
Grade A, and why
material3-design-system 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 12d 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 — KMP / Compose Multiplatform Skill
This skill guides implementation of Google's Material Design 3 (MD3 / Material You) using Jetpack Compose and Compose Multiplatform for KMP projects (Android + Desktop).
Attribution: This skill is adapted from and gives credit to hamen/material-3-skill by Hamen. The original skill covers web and Flutter targets. This KMP edition strips all web/CSS/Flutter patterns and replaces them with pure Compose Multiplatform APIs, adds the audit report system, and extends the reference set for adaptive layout, navigation, and versioning.
Scope: Compose-only. All examples use
androidx.compose.material3APIs — the same API surface is available in KMPcommonMainviaorg.jetbrains.compose.material3:material3(declared explicitly inlibs.versions.toml). No web CSS, no@material/webelements, no Flutter.
MD3 Philosophy
| Principle | What it means in Compose |
|---|---|
| Personal | Dynamic color from user wallpaper (Android 12+). Static fallback for Desktop. |
| Adaptive | WindowSizeClass drives layout changes across compact → expanded screens. |
| Expressive | Spring-based motion, shape morphing, emphasized typography. |
Google I/O 2026 Key Updates
- Compose-first on Android: For all new Android work, use
androidx.compose.material3. - Expressive layout scaffold: Design screens to adapt across mobile, desktop, foldables. Use
Material3Adaptivescaffold APIs. - 8dp spacing system: Define spacing as tokens — never scatter raw
Dpliterals. - New expressive components: Lists, menus, search, and search app bars have refreshed expressive guidance; check your Material3 BOM for expressive variants.
Design Token System
All MD3 values come through MaterialTheme. Never hardcode raw values inline.
| Token category | Access in Compose |
|---|---|
| Color | MaterialTheme.colorScheme.* |
| Typography | MaterialTheme.typography.* |
| Shape | MaterialTheme.shapes.* |
| Spacing | Define a Dimens object (no built-in API) |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

material3-design-system is a skill published in the GitHub repository iammohdzaki/kmp-skills (4 stars, last pushed 1mo ago), licensed MIT. It adds 71 tokens to every session and 6,326 once invoked, about $0.0004 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 2026-08-31.
