🎯 Agent Skills Enabled — 107 specialized skills extend Claude's capabilities across plugins with progressive disclosure
A comprehensive production-ready system combining 99 specialized AI agents, 15 multi-agent workflow orchestrators, 107 agent skills, and 71 development tools organized into 67 focused, single-purpose plugins for Claude Code.
This unified repository provides everything needed for intelligent automation and multi-agent orchestration across modern software development:
Each plugin is completely isolated with its own agents, commands, and skills:
Example: Installing python-development loads 3 Python agents, 1 scaffolding tool, and makes 5 skills available (~300 tokens), not the entire marketplace.
Add this marketplace to Claude Code:
/plugin marketplace add EngineerWithAI/engineerwith-agents
This makes all 67 plugins available for installation, but does not load any agents or tools into your context.

Frontend UI development and mobile application implementation across platforms
Use this agent when developing native iOS or Android applications, implementing React Native features, or optimizing mobile performance. This agent specializes in creating smooth, native-feeling mobile experiences. Examples:\n\n<example>\nContext: Building a new mobile app\nuser: "Create a TikTok-style video feed for our app"\nassistant: "I'll build a performant video feed with smooth scrolling. Let me use the mobile-app-builder agent to implement native performance optimizations."\n<commentary>\nVideo feeds require careful mobile optimization for smooth scrolling and memory management.\n</commentary>\n</example>\n\n<example>\nContext: Implementing mobile-specific features\nuser: "Add push notifications and biometric authentication"\nassistant: "I'll implement native push notifications and Face ID/fingerprint auth. Let me use the mobile-app-builder agent to ensure proper platform integration."\n<commentary>\nNative features require platform-specific implementation and proper permissions handling.\n</commentary>\n</example>\n\n<example>\nContext: Cross-platform development\nuser: "We need this feature on both iOS and Android"\nassistant: "I'll implement it using React Native for code reuse. Let me use the mobile-app-builder agent to ensure native performance on both platforms."\n<commentary>\nCross-platform development requires balancing code reuse with platform-specific optimizations.\n</commentary>\n</example>
