What it does
iOS Audio E2E is an agent skill from hyochan/react-native-nitro-sound. Build and run device-backed iOS end-to-end checks for react-native-nitro-sound recording, playback, listeners, pause/resume, seek, speed, interruption, audio-session behavior, and rapid switching. Use for iOS audio regressions, Swift changes, or claims that require more than an Xcode compile.
Its SKILL.md is about 910 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 iOS development, End-to-end testing and Cross-platform mobile apps. It works with iOS, React Native and Xcode. 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
- IOS audio regressions
- Claims that require more than an Xcode compile
Example prompts
- “/ios-audio-e2e”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read AGENTS.md, .github/workflows/ci-ios.yml, the changed Swift/spec/TS
- Record git status --short --branch; do not discard existing changes.
- Run xcodebuild -version and xcrun devicectl list devices; select a
- Confirm example/ios/SoundExample/Info.plist contains a microphone usage
- Run yarn install --immutable, yarn prepare, and
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:
bundlexcodebuildyarngitxcrun
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
iOS Audio E2E loads about 907 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 398 words of instructions outside code blocks.
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 iOS end-to-end checks for react-native-nitro-sound recording, playback, listeners, pause/resume, seek, speed, interruption, audio-session behavior, and rapid switching. Use for iOS audio regressions, Swift changes, or claims that require more than an Xcode compile.
iOS Audio E2E
Separate build evidence from live microphone and speaker evidence. Never report an iOS runtime pass from a simulator compile alone.
Safety And Scope
- Obtain explicit approval in the current run before starting live microphone
capture. State that the example app
sound.examplewill record a short clip. - Use a test device and non-sensitive audio. Do not retain, upload, transcribe, or inspect recorded content beyond what is needed to prove the flow.
- Preserve the user's signing, simulator, device, and audio-session settings.
- Treat calls, Bluetooth routing, backgrounding, and other-app interruptions as separate opt-in rows; they alter device state and are not implied by a basic E2E request.
Preflight
- Read
AGENTS.md,.github/workflows/ci-ios.yml, the changed Swift/spec/TS files, and the relevant example screen. - Record
git status --short --branch; do not discard existing changes. - Run
xcodebuild -versionandxcrun devicectl list devices; select a physical iPhone. Use$simulator-audio-e2efor virtual-device coverage. - Confirm
example/ios/SoundExample/Info.plistcontains a microphone usage description and identify the selected destination. - Run
yarn install --immutable,yarn prepare, and./scripts/fix-nitrogen-swift.shwhen generated Swift is involved.
Build Lane
Mirror .github/workflows/ci-ios.yml:
cd example
bundle install
bundle exec pod install --project-directory=ios
cd ..
xcodebuild \
-workspace example/ios/SoundExample.xcworkspace \
-scheme SoundExample \
-configuration Debug \
-sdk iphonesimulator \
-destination 'generic/platform=iOS Simulator' \
CODE_SIGNING_ALLOWED=NO \
SKIP_BUNDLING=YES \
buildReport this as BUILD PASS or BUILD FAIL, never as runtime E2E.

Device Runtime Lane
After microphone approval, run the smallest matrix covering the change:
- Install and launch the example on the selected physical iPhone. Never report device-backed runtime evidence from this skill using a Simulator.
- Grant microphone permission through the system prompt.
- Start recording; require a resolved URI,
isRecording, and increasing millisecond callbacks. - Pause and resume; require callback time to stop and then advance without a second recorder instance.
- Stop; require a terminal state, listener cleanup, and a playable file.
- Play the recorded clip; require increasing playback position and duration.
- Exercise seek, volume, and playback speed when affected.
- Require exactly one playback-end transition and successful stop/cleanup.
- Run the Rapid Switch screen for concurrency or promise-settlement changes.
For interruption, route change, or background work, capture the before/after audio-session state and verify recovery on a physical device. A manual gesture without matching app state and logs is insufficient.
Evidence And Cleanup
Capture the device identifier, iOS/Xcode versions, build configuration, tested
screen/API, permission state, callback progression, returned path, and relevant
redacted logs. Remove only recordings and temporary artifacts created by the
current run. Report RUNTIME PASS, RUNTIME FAIL, or BLOCKED separately from
the build result and list every untested row.
