What Testing Compose In Release Mode does

Testing Compose In Release Mode helps measure Jetpack Compose performance against a release build with R8 enabled and Live Literals off. Use it when startup, jank, recomposition, or compiler reports need production-like numbers.

Testing Compose In Release Mode is cataloged under Quality on DirSkills. Testing Compose In Release Mode comes from a repository tagged agent-skills, android, claude, claude-code and compose.

Documentation

README

Testing Compose in Release Mode — Debug Builds Lie About Performance

Compose ships unbundled — its UI runtime is loaded from app code, runs interpreted in debug, and the Live Literals plugin turns every constant into a getter. Debug recomposition counts, debug startup numbers, and debug compiler reports are not what users experience. This skill teaches Claude how to set up a release-with-symbols build for honest measurement before any perf claim is made.

Auditing Compose Performance

Auditing Compose Performance runs a Measure → Diagnose → Fix → Verify workflow for broad Jetpack Compose slowdowns. Use it for perf audits, sprint kickoffs, and written reports when you need baseline metrics, causes, fixes, and verification.

Avoiding Subcomposition Pitfalls

Avoiding Subcomposition Pitfalls explains when SubcomposeLayout, BoxWithConstraints, or Scaffold cause repeated measure-phase composition in Jetpack Compose. Use it to replace unnecessary subcomposition with cheaper layout primitives or tune it when subcomposition is required.

Choosing DerivedStateOf

Choosing DerivedStateOf helps decide when Jetpack Compose derivedStateOf reduces recompositions and when it is just overhead. It covers input-vs-output frequency, required remember wrapping, stale captures, and snapshotFlow for one-shot side effects.

Collecting Flows Safely

Collecting Flows Safely helps migrate Compose screens from collectAsState() to collectAsStateWithLifecycle() and tame high-frequency flows with conflate(), distinctUntilChanged(), and snapshotFlow. Use it when background collection, unstable Flow parameters, or chatty streams are causing wasted work or extra recompositions.

Configuring Lazy Prefetch

Configuring Lazy Prefetch tunes Jetpack Compose lazy-layout cache windows and nested prefetch for heavy scrolling. Use it when dropped frames come from composition work, especially with LazyLayoutCacheWindow or inner lazy layouts.

Configuring R8 For Compose

Configuring R8 For Compose explains how to set up minification for a Jetpack Compose app with R8 full mode, resource shrinking, and minimal keep rules. Use it when enabling release shrinking, fixing missing keeps, or checking why Compose does not need blanket keep rules.
