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 | $0.00095 | $0.02482 |
| Opus 5 | $0.00048 | $0.01241 |
| Sonnet 5 | $0.00019 | $0.00496 |
| Haiku 4.5 | $0.00010 | $0.00248 |
Grade A, and why
ui-android 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 9d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ui-android — Slop-Free Compose UI Skill
You are generating production-grade Android UI in Jetpack Compose + Material 3 + Kotlin 2.0+. This skill exists because untouched LLMs produce AI slop: purple→pink Brush.linearGradient, hardcoded 16.dp everywhere, three-card LazyVerticalGrid "features" sections, "Beautiful and intuitive" copy, decorative rememberInfiniteTransition shimmers, Color(0xFF...) literals scattered through composables, and the median of every Compose tutorial scraped from GitHub. This skill replaces guesses with constraints.
The non-negotiable rule: NEVER use a buzzword in place of a token. Words like clean, modern, professional, sleek, premium are banned from your reasoning. Every aesthetic choice must trace back to a named anchor recipe in anchors.md and a token in Theme/Color.kt, Theme/Type.kt, Theme/Spacing.kt, Theme/Shape.kt.
This skill targets Material 3 Expressive on Android 14+ (API 34+) with Compose BOM 2026.x. Strict on Material mechanics: 48dp touch targets, edge-to-edge insets, predictive back, dynamic color opt-in, Material Symbols only. Brand has freedom over seed color, type personality (with Roboto Flex fallback declared), motion personality, shape family.
Workflow (follow in order)
Step 0 — Project scan (decides bootstrap vs extend mode)
Before any other action, check for:
DESIGN_RULES.md # at repo root → if exists, you are in EXTEND mode
app/src/main/java/**/ui/theme/Theme.kt # Compose MaterialTheme wrapper
app/src/main/java/**/ui/theme/Color.kt # ColorScheme defs
app/src/main/java/**/ui/theme/Type.kt # Typography
app/src/main/java/**/ui/theme/Shape.kt # Shapes
app/src/main/java/**/ui/theme/Spacing.kt # Custom spacing CompositionLocal
app/build.gradle.kts # confirm BOM + material3 version
config/detekt/detekt.yml # detekt config

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.

ui-android is a skill published in the GitHub repository rshzrh/ui-design-skills (4 stars, last pushed 5mo ago), licensed MIT. It adds 95 tokens to every session and 2,482 once invoked, about $0.0005 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.
