How does it handle platform-specific features?

It promotes the use of optionality and escape hatches to expose native functionality directly while maintaining a unified cross-platform interface similar to W3C standards.

Can it help with app permissions and entitlements?

Yes, the skill includes best practices for creating Expo Config Plugins to automate the setup of iOS entitlements and Android permissions in managed projects.

What are Shared Objects in this context?

Shared Objects are long-lived native instances shared with JavaScript, allowing you to maintain heavy state (like decoded bitmaps) across React component mounts without re-instantiation.

Does this skill support the legacy React Native bridge?

No, it exclusively focuses on the New Architecture and the modern Expo Modules API to ensure maximum performance, type safety, and future-proofing.
