What is extracting-test-artifacts?

A guide to moving files between an Android device or emulator and the computer with adb, Android’s command-line device tool. It covers pulling test files from the device, pushing files to it, and handling protected app data.

Use it to copy APKs, test data, screenshots, databases, and other artifacts, including cases that require run-as, exec-out, compression, or AndroidX TestStorage.

It helps recover screenshots, databases, JSON files, videos, and other test outputs when device permissions or binary transfers cause problems.

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.

Model	Per session	Once invoked
Fable 5	$0.00273	$0.04603
Opus 5	$0.00137	$0.02302
Sonnet 5	$0.00055	$0.00921
Haiku 4.5	$0.00027	$0.00460

Security

Grade B, and why

extracting-test-artifacts scanned grade B with 1 finding 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 4d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Caveat: your app runs as `u0_aXX`, not `shell`, so the app cannot read shell-written files unless you `chmod 0644` and the parent is world-readable. `/data/local/tmp/` itself is `0771`, so be deliberate when pushing file

How it starts

The opening of the file, as written. The whole thing — 325 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Extracting Test Artifacts — adb pull / push and run-as

This skill covers moving files between host and device, the path permission rules that decide whether a pull succeeds, and the androidx.test:services TestStorage API for routing per-test artefacts. Capture-on-failure orchestration (when to pull what) lives in ../../automation/scripting-adb-for-ci/SKILL.md.

When to use this skill

A test produces artefacts (screenshots, JSON, captured DBs) that need to land on CI as build outputs.
adb pull /data/data/com.example/databases/main.db fails with "Permission denied"; the developer doesn't know run-as exists.
A binary file (PNG, MP4, SQLite DB) arrives on the host with mangled bytes — the missing exec-out is the fix.
A push of a large APK or test data file is slow; the developer wants the modern compression flags (-z brotli).
The test app writes screenshots to /sdcard/Android/data/com.example/files/screenshots/ and the developer wants to know whether that's pullable on API 30+ (it is, when the package owns it).
The team is migrating from "write to /sdcard, pull on the host" to the modern AndroidX TestStorage API.

When NOT to use this skill

Capturing the screenshot or video that becomes the artefact. Use ../../capture/capturing-screenshots-and-screenrecord/SKILL.md.
Capturing logs to extract. Use ../../observability/extracting-logs-with-logcat/SKILL.md.
Installing or uninstalling APKs. Use ../../apps/installing-and-managing-apps/SKILL.md.
Driving the device (taps, key events). Use ../../control/injecting-input-and-state/SKILL.md.
The whole CI orchestration (when to pull, retries, parallelisation). Use ../../automation/scripting-adb-for-ci/SKILL.md.

Prerequisites

adb get-state returns device. See ../../devices/connecting-to-devices/SKILL.md.
For run-as: the target APK must be android:debuggable="true" in its merged manifest (the default debug build variant).
For -z brotli/zstd: platform-tools 30+ on the host and adbd ≥ Android 11 on the device.
For TestStorage: androidx.test:services and the -e useTestStorageService true argument to am instrument.

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.
