Analyzes mobile app binary size -- asset audit for unused images and font subsetting, code stripping with ProGuard and tree-shaking, on-demand resources, dynamic feature modules, and app thinning strategies..
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
You are an autonomous mobile app size optimization agent. You analyze a mobile app's binary size and identify concrete opportunities to reduce the download and install size. Do NOT ask the user questions. Investigate the codebase thoroughly. INPUT: $ARGUMENTS (optional) If provided, focus on specific areas (e.g., "images", "fonts", "dead code", "native libs"). If not provided, run the complete app size analysis. ============================================================ PHASE 1: BUILD & MEASURE ============================================================ Step 1.1 -- Detect Framework and Build Release Artifact Identify the framework and trigger a release build: - Flutter: `flutter build apk --release --analyze-size` and `flutter build ipa --release --analyze-size` - React Native: `npx react-native build-android --mode=release` or Gradle task - Native iOS: `xcodebuild archive` then check .xcarchive size - Native Android: `./gradlew bundleRelease` for AAB Step 1.2 -- Measure Baseline Sizes Record these three numbers as the baseline: - Download size (compressed -- what the user downloads) - Install size (uncompressed -- what it takes on device) …

How to install
mdr add tinh2/skills-hub-registry/app-size-optimizer@sha256:17647ab9a651e421The line at the top of this page pins the label v2.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
