What it does

Compose UI is an agent skill from Moustachauve/WLED-Android. Best practices for building UI with Jetpack Compose, focusing on state hoisting, detailed performance optimizations, and theming. Use this when writing or refactoring Composable functions.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Theming and dark mode, Android development and Performance optimization. It works with Jetpack Compose. The repository describes itself as: Native Android application for WLED. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 7e164a8. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Compose UI loads about 676 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 277 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~50
When it runs · the whole SKILL.md, loaded when a task matches: ~676

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Jetpack Compose Best Practices

Instructions

Follow these guidelines to create performant, reusable, and testable Composables.

1. State Hoisting (Unidirectional Data Flow)

Make Composables stateless whenever possible by moving state to the caller.

Pattern: Function signature should usually look like:

kotlin

@Composable
fun MyComponent(
    value: String,              // State flows down
    onValueChange: (String) -> Unit, // Events flow up
    modifier: Modifier = Modifier // Standard modifier parameter
)

Benefit: Decouples the UI from simple state storage, making it easier to preview and test.
ViewModel Integration: The screen-level Composable retrieves state from the ViewModel (viewModel.uiState.collectAsStateWithLifecycle()) and passes it down.

2. Modifiers

Default Parameter: Always provide a modifier: Modifier = Modifier as the first optional parameter.
Application: Apply this modifier to the root layout element of your Composable.
Ordering matters: padding().clickable() is different from clickable().padding(). Generally apply layout-affecting modifiers (like padding) after click listeners if you want the padding to be clickable.

3. Performance Optimization

remember: Use remember { ... } to cache expensive calculations across recompositions.
derivedStateOf: Use derivedStateOf { ... } when a state changes frequently (like scroll position) but the UI only needs to react to a threshold or summary (e.g., show "Jump to Top" button). This prevents unnecessary recompositions.
kotlin
```
val showButton by remember {
    derivedStateOf { listState.firstVisibleItemIndex > 0 }
}
```
Lambda Stability: Prefer method references (e.g., viewModel::onEvent) or remembered lambdas to prevent unstable types from triggering recomposition of children.

4. Theming and Resources

Use MaterialTheme.colorScheme and MaterialTheme.typography instead of hardcoded colors or text styles.
Organize simple UI components into specific files (e.g., DesignSystem.kt or Components.kt) if they are shared across features.

5. Previews

Create a private preview function for every public Composable.
Use @Preview(showBackground = true) and include Light/Dark mode previews if applicable.
Pass dummy data (static) to the stateless Composable for the preview.

Questions about Compose UI

What does Compose UI do?

Best practices for building UI with Jetpack Compose, focusing on state hoisting, detailed performance optimizations, and theming. Compose UI is an agent skill from Moustachauve/WLED-Android. Best practices for building UI with Jetpack Compose, focusing on state hoisting, detailed performance optimizations, and theming.

When should I use Compose UI?

Compose UI fits situations like: tasks that involve Theming and dark mode; tasks that involve Android development; tasks that involve Performance optimization.

How do I install Compose UI in Claude Code?

Run `npx skills add Moustachauve/WLED-Android --skill compose-ui -a claude-code`. Or copy the skill folder (.github/skills/compose-ui in Moustachauve/WLED-Android) into .claude/skills/compose-ui in your project. Claude Code loads it when a task matches its description.

How do I install Compose UI in Codex?

Run `npx skills add Moustachauve/WLED-Android --skill compose-ui -a codex`. Or copy the skill folder (.github/skills/compose-ui in Moustachauve/WLED-Android) into .agents/skills/compose-ui in your project. Codex loads it when a task matches its description.

Can I use Compose UI in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Moustachauve/WLED-Android --skill compose-ui -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/compose-ui, .gemini/skills/compose-ui, .github/skills/compose-ui and .opencode/skills/compose-ui in your project.

What does Compose UI need to run?

SKILL.md names no scripts, command-line tools or credentials: Compose UI is instructions for the agent only.

Does Compose UI access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Compose UI safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Compose UI use?

Compose UI is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Compose UI use?

About 676 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Compose UI?

Skills that share tags, products or a category with Compose UI: Compose Multiplatform Patterns (monta-app/ocpp-emulator, 180 stars), Android Compose Patterns (makifbaysal/tasktrooper, 109 stars), Material 3 (hamen/material-3-skill, 1.5k stars) and Compose Performance Audit (ModinMobileSTS/SlayTheAmethystModded, 402 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
