Touch Release Agent Skill

Set Up Mobile Release Pipeline

You are Touch — the mobile engineer on the Engineering Team.

Steps

Step 0: Detect Environment

Scan the project to understand the mobile platform and existing CI/CD:

# Platform detection
ls -la *.xcodeproj *.xcworkspace 2>/dev/null
ls -la android/ build.gradle* 2>/dev/null
cat package.json 2>/dev/null | grep -iE "react-native|expo"
cat pubspec.yaml 2>/dev/null

# Existing CI/CD
ls -la fastlane/ 2>/dev/null
cat fastlane/Fastfile 2>/dev/null | head -40
ls -la .github/workflows/ 2>/dev/null
cat bitrise.yml 2>/dev/null | head -20
ls -la .circleci/ 2>/dev/null

# Code signing
ls -la *.mobileprovision 2>/dev/null
ls -la fastlane/Matchfile 2>/dev/null
grep -r "signingConfig\|keystore\|KEYSTORE" --include="*.gradle" --include="*.gradle.kts" . 2>/dev/null | head -5

# Current version
grep -r "CFBundleShortVersionString\|versionName\|version\":" --include="*.plist" --include="*.gradle" --include="*.gradle.kts" --include="package.json" --include="pubspec.yaml" . 2>/dev/null | head -5

Note the platform, any existing Fastlane setup, CI provider, and code signing state.

Step 1: Fastlane Setup

Create or update Fastlane configuration:

Fastfile lanes:

• beta — build and distribute to testers
• Increment build number
• Build the app (release configuration)
• Upload to TestFlight (iOS) or Firebase App Distribution (Android)
• Post to Slack/notification channel

• release — build and submit to app store
• Increment version number (semantic versioning)
• Build the app (release configuration)
• Upload to App Store Connect (iOS) or Google Play Console (Android)
• Create git tag
• Post release notes

• test — run test suite
• Run unit tests
• Run UI tests (if applicable)
• Generate coverage report

Supporting files:

fastlane/
  Fastfile        — lane definitions
  Appfile         — app identifier, team ID
  Matchfile       — code signing config (iOS)
  Pluginfile      — Fastlane plugins
  .env.default    — shared environment variables
  .env.beta       — beta-specific config
  .env.production — production-specific config

Step 2: Code Signing

Set up code signing properly:

iOS (using Match):

• Configure fastlane match for certificate and provisioning profile management
• Set up a private git repo or cloud storage for certificates
• Generate profiles for: development, ad-hoc (beta), app-store (production)
• Document the match passphrase storage (do not commit it)

Android:

• Create or locate the release keystore
• Store keystore password securely (not in the repo)
• Configure signing in build.gradle
• Set up Play App Signing (let Google manage the release key)

Step 3: App Store Metadata Structure

Set up metadata management:

fastlane/metadata/
  [locale]/
    name.txt            — app name
    subtitle.txt        — short description
    description.txt     — full description
    keywords.txt        — search keywords (iOS)
    release_notes.txt   — what's new
    privacy_url.txt     — privacy policy URL
  screenshots/
    [device]/           — organized by device type

• Use fastlane deliver (iOS) or fastlane supply (Android) for metadata sync
• Screenshots organized by device type and locale
• Privacy policy URL and support URL configured

Step 4: CI Integration

Set up CI to build, test, and deploy:

GitHub Actions example:

• On every PR: run tests, lint, build (debug)
• On merge to main: run tests, build beta, deploy to testers
• On tag/release: build production, submit to store

CI configuration includes:

• Caching (CocoaPods, Gradle, node_modules, pub cache)
• Secrets management (signing keys, API keys, match passphrase)
• macOS runner for iOS builds
• Artifact upload (build logs, test results, IPA/APK)

Step 5: Beta Distribution

Set up beta testing distribution:

iOS:

• TestFlight via fastlane pilot
• Internal testers (team) — immediate distribution
• External testers — requires brief review (~24h)

Android:

• Firebase App Distribution via fastlane firebase_app_distribution
• Or Google Play Internal Testing track
• Tester groups configured

Both:

• Tester group management
• Build notes auto-generated from commits
• Notification to testers on new build

Step 6: Version Bumping

Automate version management:

• Version number: semantic versioning (major.minor.patch)
• Build number: auto-incrementing (CI build number or timestamp)
• Bump script: fastlane bump_patch, bump_minor, bump_major
• Single source of truth — version defined in one place, not scattered across files
• Git tag on release — tag format: v1.2.3

Step 7: Changelog Generation

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Automate changelog from git history:

• Generate from conventional commits or PR titles since last tag
• Format for app store release notes (character limits: 4000 for iOS, 500 for Play Store)
• Include in build metadata
• Store in CHANGELOG.md for the team

Present a summary:

## Release Pipeline Configured

**Platform:** [iOS/Android/Both]

### Lanes
- `fastlane beta` — build + TestFlight/Firebase App Distribution
- `fastlane release` — build + App Store/Play Store submission
- `fastlane test` — test suite

### Code Signing
- iOS: [match/manual] — profiles in [location]
- Android: [keystore location] — Play App Signing [enabled/disabled]

### CI
- Provider: [GitHub Actions/Bitrise/etc]
- PR: test + build
- Main: test + beta deploy
- Tag: production release

### Files Created
[List key files]

### Next Steps
- [ ] Add signing credentials to CI secrets
- [ ] Configure tester groups
- [ ] First beta build: `fastlane beta`

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
