Skill UI

This skill provides a robust mechanism for extending an existing API gateway by adding custom, non-GraphQL HTTP endpoints (GET, POST, PUT, etc.). Developers can implement the Route.Interface and register it using the <Api.Route> component. It supports full Dependency Injection (DI), providing framework-agnostic Request and Reply objects, making it ideal for integrating complex business logic directly into the API structure.

This skill provides a powerful mechanism for modifying and extending AWS infrastructure using Pulumi handlers and dedicated declarative components. It allows developers to manage complex cloud setups, including configuring OpenSearch, VPC networking, resource tagging, custom domains, blue-green deployment strategies, and implementing environment-conditional configurations (e.g., production vs. development).

This skill guides the implementation of robust GraphQL APIs using Golang. It covers best practices for schema design (SDL), writing efficient resolvers, and critically, preventing N+1 database query issues using DataLoaders. Essential for building scalable, production-ready backend services.

Expert assistance for building, modifying, and debugging Minecraft server plugins for the Paper, Spigot, and Bukkit ecosystems. This includes implementing complex gameplay mechanics such as minigames, advanced combat systems, persistent player progression (perks, economy, quests), custom command handling, and robust state management. We handle configuration, listener registration, and adherence to best practices for Java-based server API usage.

An expert playbook for systematically testing Insecure Direct Object References (IDOR) and Broken Object/Function Level Authorization (BOLA/BFLA). This guide covers finding object identifiers across all request vectors (URL, body, headers, cookies), implementing A-B testing methodologies, identifying various ID patterns, and executing horizontal or vertical privilege escalation attacks. Essential for deep API security auditing.

This catalog provides 11 core abstractions for implementing robust mailing functionalities within the Webiny API architecture. It includes Use Cases, Repositories, and various Event Handlers (e.g., before/after send, save). Developers should use these structured patterns to ensure their mailer logic is modular, highly testable, and follows industry best practices.

A comprehensive playbook detailing advanced techniques for bypassing modern Endpoint Detection and Response (EDR) and Antivirus (AV) solutions on Windows. Covers exploiting vulnerabilities in AMSI, ETW, and implementing sophisticated process injection methods (e.g., Process Hollowing, Early Bird) to execute payloads while maintaining stealth.

This alias serves as a specialized Codex CLI interface for implementing the P7 protocol, mimicking the workflow of a P7 senior engineer. It enforces a highly structured development cycle: detailed planning, robust implementation, mandatory self-review (via three critical questions), and final, verifiable completion markers. Ideal for complex coding tasks requiring maximum rigor and accountability.

This guide outlines architectural patterns and best practices for building scalable, production-ready APIs with FastAPI. It covers proper project structure, separating concerns using routers, services, and CRUD layers, implementing dependency injection for database sessions and authentication, defining Pydantic schemas for request/response, handling asynchronous operations, and managing custom error responses.

A comprehensive toolkit providing source generators and base classes for implementing the Model-View-ViewModel (MVVM) pattern in .NET applications. It simplifies the creation of observable properties, commands, and validation logic, significantly reducing boilerplate code. Supports major cross-platform UI frameworks including WPF, WinUI 3, MAUI, and Avalonia.

This skill guides developers on integrating CommunityToolkit.Mvvm ViewModels with Microsoft's Dependency Injection system. It covers setting up the composition root using the .NET Generic Host, managing service lifetimes (Singleton, Transient, Scoped), implementing constructor injection, and correctly registering messaging services (IMessenger) for robust, cross-platform XAML applications (WPF, MAUI, Uno, Avalonia).

This comprehensive guide covers best practices for building modern Angular applications. It provides detailed instructions on component architecture, state management using Signals, advanced routing, dependency injection, handling forms (prioritizing Signal Forms), and implementing accessibility (ARIA). It also details setup procedures for new projects and modern rendering strategies like SSR.
