Expo Dev Assistant provides AI-driven management of Expo and React Native projects through the Expo Application Services (EAS) platform. It enables end-to-end mobile development workflows from initial project setup to production deployment across iOS and Android. Key features include: - Project scaffolding and configuration management with support for creating new projects, installing packages, validating app config, and generating native iOS/Android code via prebuild - Cloud-based CI/CD pipelines through EAS Build for compiling iOS and Android apps with real-time build status monitoring, log streaming, and cancellation controls - Over-the-air (OTA) update publishing to instantly deploy JavaScript changes to specific branches and channels without app store review delays - Automated app store submissions to Apple App Store Connect and Google Play Console through EAS Submit - Built-in diagnostics with health checks and configuration validation via `expo doctor` - LLM-optimized documentation access covering Expo CLI reference, EAS Build, EAS Update, and EAS Submit guides
