What it does

Diagnose and optimize Android Jetpack Compose UI code. Use this skill when analyzing performance bottlenecks of existing code to minimize recomposition overhead and prevent dropped frames and UI lag.

Foundational prerequisites

Before micro-optimizing composables, ensure standard production flags are in place:

  1. Release Build: Never profile or benchmark debuggable builds; ART runtime verification severely degrades performance.
  2. R8 Minification: Keep R8 enabled to optimize bytecode and coroutine dispatch.
  3. Baseline Profiles: Generate baseline profiles for critical user journeys (cold start, key scrolling feeds) so the ART VM pre-compiles and preloads classes ahead of time.

Optimization audit workflow

  1. Exhaustive Scan : Scan the target code against all 7 core categories in the following sections. Evaluate every @Composable function, modifier chain, and lazy-layout data model against all checklist rules rather than stopping after the first issue found.
  2. Mandatory Reference Read Before Flagging or Editing : Whenever a file matches a rule in Categories 1--7, you MUST open and read the corresponding references/*.md file for the approved fix pattern and full scope guards before reporting a finding or editing code. Never rely on the summary bullets alone to write fixes.

1. State, snapshots, and stability (references/state-and-stability.md)

MANDATORY : Before flagging or fixing any issue in this category, you MUST read references/state-and-stability.md.
