What it does

Android Audio E2E is an agent skill from hyochan/react-native-nitro-sound. Build and run device-backed Android end-to-end checks for react-native-nitro-sound permissions, recording, playback, listeners, pause/resume, seek, speed, audio focus, lifecycle behavior, and rapid switching. Use for Kotlin or Android regressions and runtime claims beyond a Gradle compile.

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Mobile, covering End-to-end testing, Cross-platform mobile apps and Android development. It works with Android, Kotlin, React Native and Gradle. The repository describes itself as: react-native native module for audio recorder and player with nitromodule! The licence is MIT.

When your agent uses it

  • Android regressions and runtime claims beyond a Gradle compile
  • Tasks that involve End-to-end testing
  • Tasks that involve Cross-platform mobile apps

Example prompts

  • “/android-audio-e2e”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Read AGENTS.md, .github/workflows/ci-android.yml, the changed
  2. Record git status --short --branch and adb devices -l.
  3. Confirm JDK 17, the Android SDK, and a single intended emulator or device.
  4. Verify RECORD_AUDIO appears in the example manifest and identify the
  5. Run yarn install --immutable and yarn nitrogen when generated Android

What it can do on your machine

Read from SKILL.md and the folder at commit efd5e54. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • yarn
    • adb
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use yarn and git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Android Audio E2E loads about 814 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~814

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Build and run device-backed Android end-to-end checks for react-native-nitro-sound permissions, recording, playback, listeners, pause/resume, seek, speed, audio focus, lifecycle behavior, and rapid switching. Use for Kotlin or Android regressions and runtime claims beyond a Gradle compile.

Android Audio E2E

Keep compilation, installation, and live audio verification as separate result lanes.

Safety And Scope

  • Obtain explicit approval in the current run before starting live microphone capture. State that the example package sound.example will record a short test clip.
  • Use non-sensitive audio. Do not upload, transcribe, or retain recordings beyond the verification need.
  • Preserve existing ADB reverse rules, permissions, accounts, and device files.
  • Test background recording, phone/audio-focus interruption, Bluetooth routing, or process death only when requested or required by the change.

Preflight

  1. Read AGENTS.md, .github/workflows/ci-android.yml, the changed Kotlin/spec/TS files, and the relevant example screen.
  2. Record git status --short --branch and adb devices -l.
  3. Confirm JDK 17, the Android SDK, and a single intended emulator or device.
  4. Verify RECORD_AUDIO appears in the example manifest and identify the current permission state without changing it.
  5. Run yarn install --immutable and yarn nitrogen when generated Android bindings are involved.

Build Lane

Mirror the CI build:

bash
yarn turbo run build:android --cache-dir=.turbo/android

If diagnosing Gradle directly, run the corresponding example task with --no-daemon --console=plain and record the exact task and architecture. Report BUILD PASS or BUILD FAIL independently.

Device Runtime Lane

After microphone approval:

  1. Install and launch sound.example on the selected device.
  2. Grant microphone permission through Android's system UI; verify denial and retry behavior when permission handling is the target.
  3. Start recording; require a resolved path, active state, and increasing millisecond callbacks.
  4. Pause and resume; require time to pause and continue without duplicate recorder instances or promise settlement.
  5. Stop; require terminal state, listener cleanup, and a non-empty app-owned recording.
  6. Play the file; require increasing position, sensible duration, seek, volume, speed, and one playback-end transition as applicable.
  7. Run Rapid Switch and Stress Test for MediaPlayer state or concurrency fixes.
  8. Inspect filtered adb logcat for uncaught exceptions, rejected promises, media-state errors, and leaked recorder/player resources.

When lifecycle, audio focus, or background behavior is in scope, explicitly exercise Home/Recent Apps, focus loss/gain, and relaunch. Do not claim process death or background support unless the exact transition was observed.

Evidence And Cleanup

Record the device serial, API level, ABI, build variant, permission state, tested API/screen, callback progression, returned path metadata, and redacted logs. Delete only recordings or temporary files created by the run. Report RUNTIME PASS, RUNTIME FAIL, or BLOCKED separately and list untested rows.
