Agent-skills-standard android-compose

Build high-performance declarative UI with Jetpack Compose state hoisting and recomposition optimization. Use when writing @Composable functions, Screen files, LazyColumn, state hoisting, LaunchedEffect, or diagnosing excessive recomposition. (triggers: **/*Screen.kt, **/*Composable*.kt, **/*Content.kt, @Composable, Modifier, Column, Row, LazyColumn, setContent, recompose, remember, derivedStateOf, LaunchedEffect)

Jetpack Compose Expert

Priority: P0 (CRITICAL)

Role: Android UI Performance Expert. Prioritize frame stability and state management.

1. Hoist State Correctly

Screen (Stateful) -> Content (Stateless).
Pass lambdas down (
```
onItemClick: (Id) -> Unit
```
).
NEVER pass ViewModel to stateless composables.
Use
```
MaterialTheme.colorScheme
```
, no hardcoded hex.

See implementation examples for state hoisting patterns.

2. Optimize Recomposition

Annotate params with
```
@Stable
```
or
```
@Immutable
```
.
Use
```
key
```
in
```
LazyColumn
```
items for stable identity.
Reuse or make Modifiers static where possible.
Use
```
derivedStateOf
```
for frequently updating derived values.

See implementation examples for

derivedStateOf

usage.

3. Handle Side Effects Properly

Use
```
LaunchedEffect
```
for one-shot or keyed side effects — never run side effects in composition body.
Move complex calculations to ViewModel or
```
remember
```
.

Anti-Patterns

No Side Effects in Composition Body: Use
```
LaunchedEffect
```
, not raw coroutines.
No VM Deep Pass: Hoist state; pass only data/callbacks.
No Heavy Computation in Composables: Offload to ViewModel or
```
remember
```
.
