gplay-preflight

gplay-preflight is a skill for Claude Code, Codex from tamtom/gplay-cli-skills. It costs 83 tokens per session (2,398 once invoked), scanned A, original, MIT.

An offline checker for Android APK and AAB build files before they are uploaded to Google Play. It scans the build and, optionally, store-listing files for release and compliance problems without using the network or credentials.

In plain words
What is it for?
Use it to inspect manifests, permissions, 64-bit support, 16 KB page alignment, listing assets, secrets, billing, privacy SDKs, target API level, and app size.
Why use it?
It can reveal issues before Google Play rejects a release or a build fails on a device. It also provides machine-readable output for automated checks in continuous integration.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is gplay preflight --file app-release.aab --listings-dir ./fastlane/metadata/android.

Good fit Use it to inspect manifests, permissions, 64-bit support, 16 KB page alignment, listing assets, secrets, billing, privacy SDKs, target API level, and app size.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gplay-preflight scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.

gplay preflight — offline build scanning

gplay preflight inspects a local .aab or .apk and reports findings. It makes no API calls and needs no credentials, so it works on any machine, in any CI job, before the artifact has ever touched Play.

Reach for it before gplay validate (which needs auth and hits the API) and before any upload. It catches the class of problem that Play rejects hours later, or that fails at install time on a user's device.

Preconditions

  • A built .aab or .apk on disk.
  • Nothing else. No gplay auth login, no --package, no network.

Basic usage

# Scan a bundle
gplay preflight --file app-release.aab

# Also validate the store listing in the same pass
gplay preflight --file app-release.aab --listings-dir ./fastlane/metadata/android

# Machine-readable
gplay preflight --file app-release.aab --output json --pretty

# See what scanners exist
gplay preflight --list-scanners

How preflight reads the build

preflight fully decodes AndroidManifest.xml — binary AXML for APKs, aapt2 protobuf for App Bundles — so findings reflect real, typed attribute values rather than substring guesses.

This matters when you interpret results: an attribute pointing at a resource reference (for example android:debuggable="@bool/isDebug") is reported as not statically determinable, not as false. Do not read a missing finding as proof of absence in that case.

Aggressive code shrinking can rename or remove classes, so SDK detection misses are not proof an SDK is absent. Matches, however, are high confidence.

The nine scanners

Every scanner has an ID. Select with --only or exclude with --skip (comma-separated).

manifest

Manifest-level correctness and release-blocking flags.

  • android:debuggable="true"error. Ships a debuggable build.
  • android:testOnly="true"error. Play rejects the upload outright.
  • Component with an <intent-filter> and no android:exported on targetSdk 31+ — error. This is an install failure on Android 12+, not a warning. Launcher activities are exempt.
  • Exported <provider> with grantUriPermissionserror. Any app can reach the granted URIs.
  • Foreground service type without its matching permission on targetSdk 34+ — Android 14 throws SecurityException at runtime. A dataSync type needs FOREGROUND_SERVICE_DATA_SYNC.
  • usesCleartextTraffic="true" — warning, downgraded to info when a networkSecurityConfig is present.
  • allowBackup, requestLegacyExternalStorage, package/version sanity.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
