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.

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.

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.

Core Data Agent Skill gives compatible AI coding tools focused guidance for Apple’s persistence framework. Its decision tree routes the agent to references on model configuration, fetch optimization, batch operations, saving, schema migration, performance, persistent history, CloudKit integration, and project audits. Developers can install it through the standard skills command, as a Claude Code plugin, or by manually linking the folder. It is intended for Swift projects needing practical Core Data diagnosis and implementation advice without imposing a particular application architecture.
