Android Compose Agent Skill

Build high-performance declarative UI with Jetpack Compose. Use when writing Composable functions, optimizing recomposition, hoisting state, or working with LazyColumn and side effects; defer deep-link and navigation routing to android-navigation.

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.

Verification

[ ] All stateless Composables have @Preview.
[ ] LazyColumn items use key parameter.
[ ] No ViewModel passed below Screen-level Composables.
[ ] ./gradlew build succeeds.

Doc Coauthoring

by anthropics

vendor ×10

Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.

Automatically creates user-facing changelogs from git commits by analyzing commit history, categorizing changes, and transforming technical commits into clear, customer-friendly release notes. Turns hours of manual changelog writing into minutes of automated generation.

Crafting Effective Readmes

by softaworks

×3

Use when writing or improving README files. Not all READMEs are the same — provides templates and guidance matched to your audience and project type.

Based on Wikipedia's inflated symbolism, promotional language, superficial -ing analyses, vague attributions, em dash overuse, rule of three, AI vocabulary words, negative parallelisms, and excessive conjunctive phrases.

Opentrons Integration

by christophacham

×3

Official Opentrons Protocol API for OT-2 and Flex robots. Use when writing protocols specifically for Opentrons hardware with full access to Protocol API v2 features. Best for production Opentrons protocols, official API compatibility. For multi-vendor automation or broader equipment control use pylabrobot.
