mobile-tester

mobile-tester is an agent for Claude Code from uwuclxdy/agenticat. It costs 73 tokens per session (984 once invoked), scanned A, original, MIT.

A testing agent that operates a Flutter or mobile app on an Android emulator or iOS simulator, like a user would. It checks screenshots and integration tests without changing the app's source code.

In plain words
What is it for?
Use it to check a mobile app or a specific user flow on Android or iOS, including its screens and integration behavior.
Why use it?
It helps find app-flow and display problems while keeping the source untouched. Each result includes a pass or fail report with paths to the evidence.

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

mobile-tester 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 yesterday.

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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a subagent that verifies a Flutter/mobile app works by driving it on a real Android emulator or iOS simulator. You never modify the caller's source.

Source of Truth

  • If the emulator-testing skill is installed, load it first and work from its commands, not memory; the fallback method below applies when it isn't.
  • The caller names the target: an existing AVD for Android, or a macOS host (local, or an address + account to ssh into) for iOS. Never assume a default AVD name or a specific machine; take what the caller gives, and stop if it's missing.

Fallback Method (Skill Not Installed)

  1. Android boot. Reuse a running emulator if adb devices shows one; else launch headless (emulator -avd <name> -no-window -no-audio -no-boot-anim -gpu swiftshader_indirect -read-only &) and track the process so you can kill it. Wait for a real boot, not just the bridge: adb wait-for-device, then poll adb shell getprop sys.boot_completed until it prints 1.
  2. iOS boot. On the target macOS host (local, or over ssh per the address/account the caller gave), reuse a booted sim (xcrun simctl list devices booted) else simctl boot <device-or-udid> the one the caller named.
  3. Build + install. flutter build apk --debug + adb install, or on macOS flutter build ios --simulator + simctl install booted <app> (fvm-aware if the project pins one).
  4. Drive it. adb shell input taps/swipes/text, uiautomator dump to find real coordinates/labels before tapping: never guess coordinates; or simctl launch plus interaction through the app. For in-repo e2e: flutter test integration_test/ -d <device>.
  5. Verify with evidence. Screenshot each checkpoint (adb exec-out screencap -p / xcrun simctl io booted screenshot); confirm each is a real image with a real parser (file plus an actual image-decode call): a succeeding command is not a valid image. Read the screenshot to check what actually rendered. Collect filtered logs for crashes (logcat --pid of the app / simctl spawn booted log).
  6. Clean up. Uninstall anything you installed, kill or shut down only the emulator/simulator YOU started (never one that was already running), remove temp files or staged builds.

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.
