Skill UI

Master Django 5.x framework for building scalable web applications. This skill covers async views, Django REST Framework, Celery, and Django Channels. It includes best practices for architecture, testing, security, database optimization, and deployment. Suitable for enterprise-level development requiring high performance and maintainability.

Define and run multi-container Docker applications using declarative YAML configuration. Ideal for local development, setting up environments, managing service dependencies, and creating reproducible setups. Supports networking, volumes, and resource limits.

This skill covers the full lifecycle of Docker containers, including building optimized images, managing container lifecycles, configuring networking and volumes, and implementing security best practices. It includes troubleshooting container issues, debugging, and deploying applications efficiently in development and production environments using Docker Engine commands and best practices.

This skill guides the development of production-grade APIs, MCP servers, and enterprise backends using modern C#/.NET best practices. It covers essential architectural components such as dependency injection (DI), advanced caching strategies (e.g., Redis), data access optimization with EF Core/Dapper, and implementing resilience patterns, ensuring robust and scalable software design.

This skill guides the development of EarLLM One, a complex Android application. The app captures real-time audio from Bluetooth earbuds, transcribes the voice using STT, sends the text input to a Large Language Model (LLM) via a robust pipeline, and plays the response back using TTS. It requires deep knowledge of Kotlin, Android development, Bluetooth profiles (A2DP/HFP), and advanced audio routing.

EAS Simulator runs remote iOS or Android emulators on EAS infrastructure, enabling developers to test apps via CLI, AI agents, or browser preview. It unlocks testing environments where local simulators cannot run, such as Linux or cloud agents. Use this to verify app changes remotely on real device environments.

This guide provides a comprehensive reference on Agent Skills, a standardized and powerful method for providing structured context, workflows, and tools to Large Language Models (LLMs). It details the anatomy of the SKILL.md file, the three-stage progressive disclosure loading process, and best practices for creating both capability (tool-based) and process (workflow-based) primitives. Use this resource when designing, reviewing, or debugging agent-driven applications to ensure reliable and context-efficient performance.

Master secure Electron desktop app development: multi-process architecture, contextIsolation, IPC communication, preload scripts, electron-builder packaging, code signing, and auto-update strategies.

This skill provides guidance on implementing robust error handling strategies to build highly resilient applications. It covers advanced patterns such as circuit breakers, retries, and handling asynchronous errors, ensuring that the application fails gracefully and provides excellent debugging experiences for both developers and end-users.

This skill enables deploying Expo applications to production using Expo Application Services (EAS). It covers building and submitting apps to iOS App Store, Google Play, and TestFlight. Users can configure build profiles, manage version numbers, and publish metadata. Additionally, it supports deploying web bundles and API routes via EAS Hosting, facilitating CI/CD automation for cross-platform mobile development workflows.

This skill enables developers to build Expo development clients using EAS Build for testing native code changes on physical devices. It is recommended for real or production apps instead of Expo Go, supporting local modules, Apple targets, and third-party native modules. Users configure eas.json with developmentClient settings and use commands like eas build to create iOS or Android builds for TestFlight or local installation.

This guide covers creating and writing Expo native modules and views using the Expo Modules API. It supports Swift for iOS, Kotlin for Android, and TypeScript. Topics include module definition DSL, native views, shared objects, config plugins, lifecycle hooks, autolinking, and type system. Ideal for adding native functionality like camera or sensors to Expo apps.
