Core-Data-Agent-Skill

Expo Skills gives compatible coding agents focused guidance for building, deploying, upgrading, and debugging Expo apps. The collection explains common Expo and EAS workflows plus React Native, iOS, and Android constraints, and can be installed through official plugin marketplaces or the skills CLI for different agents.

iOS Simulator Skill for Claude Code wraps xcodebuild for builds and tests, then uses simctl and optional idb to navigate simulators through accessibility semantics rather than fragile coordinates. Its 27 scripts cover logs, screenshots, permissions, device lifecycle, accessibility checks, and visual diffs, with progressive result caching to keep agent output focused. It requires macOS 12+, Xcode Command Line Tools, and Python 3; idb and Pillow are optional.

Awesome Android Agent Skills packages Android architecture, Jetpack Compose, data-layer, accessibility, testing, and migration practices as installable Agent Skills. Copy the skills directory and shared Agent.md context into an Android project, then compatible assistants such as GitHub Copilot, Claude, Gemini, or Cursor can load the relevant instructions for each task instead of relying on repeated prompts.

claude-android-skill gives Claude Code an opinionated workflow for modern Kotlin applications, covering Jetpack Compose, MVVM and unidirectional data flow, layered architecture, offline-first storage, Hilt, and testing. Once copied into the skills directory, it activates for Android requests and can use bundled references, Gradle templates, and a feature-module generator. The repository is still marked as work in progress and is designed around this specific Android stack.
