    Build Outcome Verifier

    Example session with this skill installed

    I just built my Flutter app and the agent said "Build successful". Before I submit to the Play Store, can you run the Build Outcome Verifier on build/app/outputs/flutter-apk/app-release.apk? Package name is com.mycompany.myapp.

    • Read your context and instructions
    • Compiled the build outcome verifier

    ❌ Build Outcome Verification — FAIL

    Artifact: build/app/outputs/flutter-apk/app-release.apk (1.1 MB)

    Installing... Success
    Launching (com.company.app/.MainActivity)... Launched
    Monitoring for 5s... Detected crash at +2.3s

    Logcat says
    FATAL EXCEPTION: main
    Process: com.company.app, PID: 12345
    java.lang.RuntimeException: Unable to start activity ComponentInfo{...}:
    Caused by: java.lang.NullPointerException: Attempt to invoke virtual method on a null object reference
    at com.company.app.MainActivity.onCreate(MainActivity.java:42)

    Result: Build artifact is BROKEN. The app crashes on launch. Pipeline should fail.

    What you get

    AI Agents That Lie About Builds — Claude Code / Codex CLI says "build successful." You install — crash on launch. This skill catches it before you waste time.CI/CD Smoke Tests — Your GitHub Actions build passes, APK is 4KB (it's a stub). This skill runs as the last CI step — install, launch, verify. If it fails, the pipeline fails, not production.Solo/Freelance Devs — No QA team. Pushing at 2am. You need to know the APK installs before Play Store submission. One command loads this skill.Multi-Agent Pipelines — Agent A builds, this skill verifies, Agent C deploys. Quality gate between stages — no broken artifacts progressing.Regression Detection — A dependency update breaks launch but compiles fine. Only a runtime smoke test catches it.

    About this skill

    Agents claim "build succeeded" constantly — but failed installs, launch crashes, and ANRs don't show up in the compiler logs.

    Build Outcome Verifier is the gatekeeper your pipeline needs.

    After any build, this skill: Installs the APK via adb — if install fails, build is rejected Launches the app and monitors for 8 seconds — if it crashes or ANRs, build is rejected (Optional) Verifies versionCode/signatures match expectations

    Only when all checks pass does the agent report "build complete."

    Who is this for? Mobile app developers using AI coding agents CI/CD pipelines that need real smoke tests before deployment Teams shipping Android builds who can't afford crash-at-install Indie developers automating their build pipeline
