    Example session with this skill installed

    Run the release checks on this app before I build.

    • Read your context and instructions
    • Compiled the store preflight

    About this skill

    A release build can compile, install and run, and still be signed with the debug key, missing a camera purpose string, or declaring iPad support with no iPad screenshots. You find out from a store rejection or, for the signing key, after Play has pinned the wrong one on a first upload.

    preflight.py works on Flutter, React Native and Expo projects. It runs last, before the build you upload, and prints one verdict per section. It exits non-zero on any error.

    Source checks

    • ANDROID-DEBUG-KEY: the release build falls back to the debug key (Flutter's Gradle does this in silence when key.properties is missing, and the React Native template signs release with the debug key by default).
    • IOS-PURPOSE: a plugin that needs an Info.plist usage string has none, or a near-empty one.
    • IOS-ENCRYPTION: no ITSAppUsesNonExemptEncryption, so every upload stops at the export-compliance question.
    • IOS-IPAD: iPad support declared with no iPad screenshots found.
    • VERSION-MISMATCH: iOS and Android version or build numbers out of step (Expo keeps them separately).
    • STALE-AAB: the .aab is older than the last commit.

    Then, in the same report

    • compliance: the app-compliance audit
    • launch: the launch-branding check
    • screenshots: the flutter-store-screenshots validator, when the app has a screenshots/ folder made by it
    • play: play-release's AAB preflight, when an .aab exists
    • ipa: the shipped .app inside an .ipa: privacy manifest included, no sample AdMob id

    A section whose skill is not installed is reported as skipped, never as passed.

    What you need: Python 3.9+ and git. No packages to install. The other sections need their skills installed.

    I build small apps on my own and have a shelf of them on the App Store and Google Play. This is the one command I run before every store build.
