This Skill helps you find and remove redundant or overly broad R8 keep rules that reduce shrinking, inflate app size, and complicate Proguard configuration troubleshooting.
proguard-rules.pro for broad/package-wide patterns and redundant rules using reference guidance.Use Case Example: You suspect your proguard-rules.pro contains package-wide -keep rules or rules that subsume library consumer keep rules, and you want to measure how much they actually prevent R8 optimizations before rewriting your configuration.
Use the r8-analyzer skill to analyze your app’s current R8 keep rules and produce a Markdown report of optimization impact based on your build configuration.

To find redundant R8 keep rules, analyze your Gradle build files and proguard-rules.pro to identify overly broad package-wide patterns and measure their optimization impact. This process outputs a Markdown report highlighting rules that reduce shrinking.
R8 full-mode readiness validates whether your Android project is configured for complete optimization. It involves checking your Gradle build files and R8-related flags to confirm setup and identify any keep rules preventing full optimization before release.
You can troubleshoot Proguard configuration issues using heuristic fallback evaluation by analyzing your proguard-rules.pro file for broad package-wide patterns and redundant rules based on reference guidance when quantitative analysis cannot run.
Yes, you can measure keep rule impact on app size optimization by running the R8 Configuration Analyzer. It quantifies how specific keep rules affect optimization and identifies the most impactful rules blocking shrinking.
Yes, the R8 Configuration Analyzer works with existing Gradle build configurations by inspecting Gradle files and gradle.properties. It evaluates your current R8 version behavior and rule impact on optimization outcomes.
