What problem does it solve? Releasing a mobile app to the iOS App Store and Google Play Store involves complex credential management, build configuration, version numbering, and store metadata. This Skill guides AI agents through the entire EAS build-and-submit pipeline so Expo apps reach production stores without manual portal work. ## Core Features & Use Cases - Production Builds & Submission: Run eas build and eas submit with production profiles for iOS and Android, including one-command TestFlight releases via npx testflight. - Store Configuration: Configure eas.json build and submit profiles, Apple App Store Connect API keys, Google Play service accounts, release tracks, and staged rollouts. - Metadata & ASO: Manage App Store listing metadata, keywords, localization, age ratings, and release strategy through EAS Metadata (store.config.json). - Use Case: A developer tags a v2.0 release and needs both platforms shipped. The Skill configures auto-incrementing version numbers, builds iOS and Android binaries, submits to TestFlight and the Play internal track, and pushes updated store metadata. ## Quick Start Ask the agent to build and submit your Expo app to TestFlight and the Google Play internal track using the production EAS profile.
