Expo Dev Client

iOS (requires Xcode)

Overview

This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/expo-dev-client from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses metadata.json plus ORIGIN.md as the provenance anchor for review.

Use EAS Build to create development clients for testing native code changes on physical devices. Use this for creating custom Expo Go clients for testing branches of your app.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: EAS Configuration, Building for TestFlight, Building Locally, Building for Specific Platform, Checking Build Status, Using the Dev Client.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• You need an Expo development client because the app depends on custom native code or targets not supported by Expo Go.
• The task involves building, distributing, or testing EAS development builds on physical devices.
• You need guidance on when to choose a dev client versus staying on plain Expo Go.
• Local Expo modules (custom native code)
• Apple targets (widgets, app clips, extensions)
• Third-party native modules not in Expo Go

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Install iOS build on simulator: bash # Find the .app in the .tar.gz output tar -xzf build-*.tar.gz xcrun simctl install booted ./path/to/App.app Install iOS build on device (requires signing): bash # Use Xcode Devices window or ideviceinstaller ideviceinstaller -i build.ipa Install Android build: bash adb install build.apk
2. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
3. Read the overview and provenance files before loading any copied upstream support files.
4. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
5. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
6. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
7. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.

Imported Workflow Notes

Imported: Installing Local Builds

Install iOS build on simulator:

# Find the .app in the .tar.gz output
tar -xzf build-*.tar.gz
xcrun simctl install booted ./path/to/App.app

Install iOS build on device (requires signing):

# Use Xcode Devices window or ideviceinstaller
ideviceinstaller -i build.ipa

Install Android build:

adb install build.apk

Imported: EAS Configuration

Ensure eas.json has a development profile:

{
  "cli": {
    "version": ">= 16.0.1",
    "appVersionSource": "remote"
  },
  "build": {
    "production": {
      "autoIncrement": true
    },
    "development": {
      "autoIncrement": true,
      "developmentClient": true
    }
  },
  "submit": {
    "production": {},
    "development": {}
  }
}

Key settings:

• developmentClient: true - Bundles expo-dev-client for development builds
• autoIncrement: true - Automatically increments build numbers
• appVersionSource: "remote" - Uses EAS as the source of truth for version numbers

Examples

Example 1: Ask for the upstream workflow directly

Use @expo-dev-client to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @expo-dev-client against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @expo-dev-client for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @expo-dev-client using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/expo-dev-client, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Load only the files that materially change the answer, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Troubleshooting Notes

Build fails with signing errors:

eas credentials

Clear build cache:

eas build -p ios --profile development --clear-cache

Check EAS CLI version:

eas --version
eas update

Imported Reference Notes

Imported: Building for TestFlight

Build iOS dev client and submit to TestFlight in one command:

eas build -p ios --profile development --submit

This will:

1. Build the development client in the cloud
2. Automatically submit to App Store Connect
3. Send you an email when the build is ready in TestFlight

After receiving the TestFlight email:

1. Download the build from TestFlight on your device
2. Launch the app to see the expo-dev-client UI
3. Connect to your local Metro bundler or scan a QR code

Imported: Building Locally

Build a development client on your machine:

# iOS (requires Xcode)
eas build -p ios --profile development --local

# Android
eas build -p android --profile development --local

Local builds output:

• iOS: .ipa file
• Android: .apk or .aab file

Imported: Building for Specific Platform

# iOS only
eas build -p ios --profile development

# Android only
eas build -p android --profile development

# Both platforms
eas build --profile development

Imported: Checking Build Status

# List recent builds
eas build:list

# View build details
eas build:view

Imported: Using the Dev Client

Once installed, the dev client provides:

• Development server connection - Enter your Metro bundler URL or scan QR
• Build information - View native build details
• Launcher UI - Switch between development servers

Connect to local development:

# Start Metro bundler
npx expo start --dev-client

# Scan QR code with dev client or enter URL manually

Imported: Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
