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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00083 | $0.02398 |
| Opus 5 | $0.00042 | $0.01199 |
| Sonnet 5 | $0.00017 | $0.00480 |
| Haiku 4.5 | $0.00008 | $0.00240 |
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
.aabor.apkon 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).

What this file has done since we first saw it
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.

gplay-preflight is a skill published in the GitHub repository tamtom/gplay-cli-skills (45 stars, last pushed 1mo ago), licensed MIT. It adds 83 tokens to every session and 2,398 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
