Testing Compose In Release Mode

Q: What is a Claude Code skill and how does the Testing Compose In Release Mode skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Testing Compose In Release Mode is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

Use this skill to ensure Jetpack Compose performance numbers reflect production reality by measuring against a release variant with R8 enabled, Live Literals disabled, and Compose Compiler reports read from the release output directory. Covers why debug builds lie (interpreted Compose runtime, JIT warmup, Live Literals constant-getters), how to set up a release-with-symbols measurement build, and how to wire Macrobenchmark, Compose Compiler reports, Layout Inspector, simpleperf, and Android Studio Profiler against it. Cited result is roughly 75 percent startup gain and 60 percent frame-render gain debug to release. Use when the developer reports "slow startup", "jank", "dropped frames", "high recomposition count", or quotes timings from `assembleDebug`, Layout Inspector, or `CompilationMode.None`. Use when reviewing a perf bug, setting up a CI perf gate, or before filing a perf regression.

About this skill (catalog notes)

Testing Compose In Release Mode includes explicit scope boundaries (an explicit 'when not to use' or 'out of scope' section); a dedicated installation section; pricing or quota commentary. At roughly 2,020 words the SKILL.md is on the longer end of the catalog distribution.

How Testing Compose In Release Mode fits the catalog

Testing Compose In Release Mode sits in the Engineering category under the testing sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.

From the source SKILL.md

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.

What this skill does

Testing Compose In Release Mode is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/testing-compose-in-release-mode/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the developer reports "slow startup", "jank", "dropped frames", "high recomposition count", or quotes timings from `assembleDebug`, Layout Inspector, or `CompilationMode.None`.

Who uses this skill

The Testing Compose In Release Mode Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 93,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
