Compose Performance Audit

new-silvermoon/awesome-android-agent-skills

A systematic workflow for hunting down Jetpack Compose performance issues, from recomposition storms to janky scrolling. Starts with code review looking for unstable parameters, missing keys in LazyColumn, and heavy work in composition blocks. If code review doesn't reveal the culprit, it walks you through profiling with Layout Inspector and Perfetto traces, then maps findings to concrete fixes like stabilizing data classes with @Immutable, remembering expensive computations, and deferring state reads to layout phase. The code smell examples are solid, especially the subtle ones like lambda captures and reading ScrollState during composition instead of in the modifier. Best used when you know something is slow but aren't sure if it's a recomposition issue or layout thrash.

Compose Performance Audit

Overview

Audit Jetpack Compose view performance end-to-end, from instrumentation and baselining to root-cause analysis and concrete remediation steps.

Workflow Decision Tree

If the user provides code, start with "Code-First Review."
If the user only describes symptoms, ask for minimal code/context, then do "Code-First Review."
If code review is inconclusive, go to "Guide the User to Profile" and ask for Layout Inspector output or Perfetto traces.

1. Code-First Review

Collect:

Target Composable code.
Data flow: state, remember, derived state, ViewModel connections.
Symptoms and reproduction steps.

Focus on:

Recomposition storms from unstable parameters or broad state changes.
Unstable keys in LazyColumn/LazyRow (key churn, missing keys).
Heavy work in composition (formatting, sorting, filtering, object allocation).
Unnecessary recompositions (missing remember, unstable classes, lambdas).
Large images without proper sizing or async loading.
Layout thrash (deep nesting, intrinsic measurements, SubcomposeLayout misuse).
