publish-mobile-app

A Claude Code skill that automates iOS App Store + Google Play Store publishing for Capacitor, Expo, or Flutter apps.

Shipping a mobile app to both stores is full of paper cuts: subtle filename rules, undocumented APIs, locale gotchas, rejection emails that quote guideline numbers nobody memorises. This skill bundles every paper cut learned shipping a real app to v1.0 — so the next one ships clean.

What it does

When you invoke /publish-mobile-app, Claude routes to one of these sub-commands:

Sub-command	What happens
status	Query both stores' APIs, report what's live vs missing
setup	Wire fastlane + gradle-play-publisher + App Store Connect API key + reviewer user (one-time, ~5 min interactive)
push	Sync listing copy + screenshots to both stores
ipa	Build signed iOS IPA → upload to TestFlight
aab	Build signed Android AAB → upload to Play internal track
release	Full lifecycle (bump + build + upload + listing push)
fix-rejection	Paste a rejection email; Claude maps to the recipe and applies the fix
checklist	Refresh a RELEASE_CHECKLIST.md at repo root

It also auto-triggers when you mention Play Store, App Store Connect, fastlane, TestFlight, or paste a store rejection email — even without the slash command.

Gotchas it captures (so you don't have to learn them again)

• LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 must be forced when invoking fastlane or Ruby crashes on em-dashes/bullets in description.txt
• App Store Connect API key path in Fastfile must be File.expand_path("../app-store-connect-key.json", __dir__) — relative paths silently fail
• iPad 2048×2732 screenshots route to the wrong slot unless filename literally contains iPad Pro (12.9-inch) (3rd generation)
• copyright.txt is non-localized (lives at metadata/copyright.txt root, not per-locale)
• Phone numbers in App Review Information need +<country> format; no spaces
• Subtitle lives on appInfoLocalizations, NOT appStoreVersionLocalizations
• Play Console default locale is often en-GB, not en-US — wrong folder = silently ignored
• "kids" / "children" in App Store subtitle → Guideline 2.3.8 rejection unless in Kids Category
• China book/magazine apps need an Internet Publishing License — easier to remove China from territories (via UI; the v2 API is undocumented)
• Fastlane's "Successfully uploaded" log is NOT equivalent to "appears in correct UI slot" — always verify via API

Full list with workarounds in REFERENCE.md.

Supported stacks

• Capacitor — ios/App/App.xcodeproj, cap sync in build pipeline
• Expo — works after expo prebuild; native EAS Build/Submit also supported as an alternative path
• Flutter — ios/Runner.xcodeproj, flutter build appbundle for Android

Prerequisites

• fastlane (Homebrew or RubyGems)
• bun or Node 18+ (for the TypeScript helper scripts)
• For iOS: Xcode + an Apple Developer account
• For Android: Android Studio + a Google Play Console developer account + a service account JSON
• For automated reviewer-user provisioning: Supabase (other backends fall back to manual instructions)

PRs welcome — especially for new rejection recipes. The skill's value compounds as more papercuts get documented. To add a recipe:
