Automated summary
This skill explains how to use the `@expo/ui/jetpack-compose` package to bring Jetpack Compose components and modifiers into an Expo app, scoped to SDK 55.
Strengths
- Covers the install step and the native rebuild requirement via `npx expo run:android`
- Clarifies the split between components (`@expo/ui/jetpack-compose`) and modifiers (`.../modifiers`)
- States the core `Host` wrapper rule with both sizing modes (`matchContents` and `style={{ flex: 1 }}`)
- Points to versioned documentation links for confirming a component's or modifier's API
Limitations
- Only targets Expo SDK 55; other versions are explicitly deferred to their own docs
- Deliberately brief: only `LazyColumn` and `Icon` get detail among the key components
- Assumes existing Jetpack Compose and Material Design 3 knowledge to pick components
Use it when building an Android UI with Expo UI and Jetpack Compose on SDK 55 and you need the import conventions, the `Host` wrapper rule, or guidance on replacing React Native lists.
Avoid it on an Expo project running a different SDK version or for iOS work, since the skill only addresses Jetpack Compose under SDK 55.
Security analysis
SafeThe skill is purely documentation for using Expo UI's Jetpack Compose package. It contains normal install and native rebuild commands, documentation URLs, and UI code examples. It does not instruct destructive actions, secret exfiltration, obfuscated payloads, or disabling safety mechanisms.

How this analysis is madeExamples
I'm using @expo/ui/jetpack-compose in my Expo app and my Column renders with zero height. How should I wrap it in Host to get intrinsic sizing?Replace this react-native FlatList in my Expo screen with a Jetpack Compose LazyColumn from @expo/ui/jetpack-compose and tell me how to size the Host.Show me how to import fillMaxWidth and paddingAll from @expo/ui/jetpack-compose/modifiers and apply them to a Column inside Host.name: expo-ui-jetpack-compose description: expo-ui-jetpack-compose risk: unknown source: community

description: @expo/ui/jetpack-compose package lets you use Jetpack Compose Views and modifiers in your app.
The instructions in this skill apply to SDK 55 only. For other SDK versions, refer to the Expo UI Jetpack Compose docs for that version for the most accurate information.
Installation
npx expo install @expo/ui
A native rebuild is required after installation (npx expo run:android).
Instructions
- Expo UI's API mirrors Jetpack Compose's API. Use Jetpack Compose and Material Design 3 knowledge to decide which components or modifiers to use.
- Components are imported from
@expo/ui/jetpack-compose, modifiers from@expo/ui/jetpack-compose/modifiers. - When about to use a component, fetch its docs to confirm the API - https://docs.expo.dev/versions/v55.0.0/sdk/ui/jetpack-compose/{component-name}/index.md
- When unsure about a modifier's API, refer to the docs - https://docs.expo.dev/versions/v55.0.0/sdk/ui/jetpack-compose/modifiers/index.md
- Every Jetpack Compose tree must be wrapped in
Host. Use<Host matchContents>for intrinsic sizing, or<Host style={{ flex: 1 }}>when you need explicit size (e.g. as a parent ofLazyColumn). Example:
import { Host, Column, Button, Text } from "@expo/ui/jetpack-compose";
import { fillMaxWidth, paddingAll } from "@expo/ui/jetpack-compose/modifiers";
<Host matchContents>
<Column verticalArrangement={{ spacedBy: 8 }} modifiers={[fillMaxWidth(), paddingAll(16)]}>
<Text style={{ typography: "titleLarge" }}>Hello</Text>
<Button onPress={() => alert("Pressed!")}>Press me</Button>
</Column>
</Host>;
Key Components
- LazyColumn — Use instead of react-native
ScrollView/FlatListfor scrollable lists. Wrap in<Host style={{ flex: 1 }}>. - Icon — Use
<Icon source={require('./icon.xml')} size={24} />with Android XML vector drawables from Material Symbols.

View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/expo-ui-jetpack-compose-ms2s7ckc/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/expo-ui-jetpack-compose-ms2s7ckc/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices

Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
