android-qa

android-qa is a skill for Claude Code from willbytee-sudo/android-qa-kit. It costs 80 tokens per session (854 once invoked), scanned A, original, MIT.

A set of instructions for testing an Android app on a real phone or an emulator, using ADB, the command-line bridge to Android devices.

In plain words
What is it for?
Use it for Android app checks such as installing an APK, navigating the app, verifying text, taking screenshots, investigating crashes, and setting up device testing.
Why use it?
It helps developers install builds, inspect screens, reproduce problems, capture evidence, and read crash logs while accounting for differences between phones and emulators.

Token cost

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

android-qa 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 1mo 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Android QA

Drive an Android device (emulator or real phone) through adb to test the user's app.

Full reference: AGENTS.md in this repository. Read it before improvising commands — it documents six verified traps, and one of them blinds you with no error output.

1. Find out what you're working with

adb devices

If adb isn't on the PATH, look in $env:ANDROID_HOME, $env:LOCALAPPDATA\Android\Sdk and C:\Android\Sdk before concluding it's missing. Android Studio installs it — many users already have it.

id looks like mode
emulator-5554 emulator
ZY22JMJD5R real device over USB
192.168.1.50:5555 real device over wireless
(empty) nothing connected — see section 4 of AGENTS.md

2. Know what your mode cannot do

Everything works in both modes except these, which are emulator-only:

  • Fake GPS (adb emu geo fix) — on a physical phone this command does not exist
  • Changing RAM
  • Wiping to a clean state

If the user asks for one of these on a real device, say so instead of trying it.

3. The working loop

adb install -r app.apk
adb shell pm list packages | Select-String their-app     # confirm the real package name
adb shell monkey -p PACKAGE -c android.intent.category.LAUNCHER 1
adb shell uiautomator dump /sdcard/ui.xml                # what's on screen
adb shell input tap 540 1200
adb logcat -d *:E

From the uiautomator dump, take each node's text and bounds. The centre of bounds is where you tap. Never eyeball pixels on a screenshot — use the dump's coordinates.

4. Two traps that will bite you

Screenshots corrupt silently in PowerShell. adb exec-out screencap -p > shot.png produces a broken PNG and reports no error — > is text redirection and destroys the binary. Always:

adb shell screencap -p /sdcard/s.png
adb pull /sdcard/s.png shot.png

Verify the header is 89 50 4E 47. If it's EF BB BF, the file is corrupt and you are blind.

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.
