Skill UI

This skill defines the mandatory conventions and architectural guidelines for building robust, cross-platform applications using Avalonia UI and the Zafiro toolkit. It emphasizes functional-reactive programming, strict MVVM adherence, and safe error handling (using Result types) to ensure high maintainability and predictability across all development features and core systems.

This skill defines mandatory architectural standards and best practices for developing robust, scalable, and observable backend services using Node.js, Express, and TypeScript. It mandates layered architecture (Routes → Controllers → Services → Repositories), strong error handling, dependency injection, and input validation (Zod) to ensure maintainability and reliability in production environments. Use when designing or refactoring core API logic.

This skill provides comprehensive guidance on leveraging d3.js (Data-Driven Documents) to create sophisticated, interactive, and publication-quality data visualizations. It covers core concepts like data binding, implementing various chart types (network graphs, geo-maps, etc.), handling complex transitions, and ensuring responsiveness across modern JavaScript frameworks (React, Vue, Vanilla JS). Learn the standard workflow for scale definition, axis creation, and drawing custom visual elements with fine-grained control.

Defines the primary CodeRabbit workflow for implementing main features, integrations, and API-driven tasks; start with setup, execute core steps, and handle errors for reliable automation.

Minimal CodeRabbit example that initializes the SDK, makes its first API call, and confirms a working connection, ideal for testing setups or learning core API patterns before building integrations.

Provides expert C#/.NET 8 guidance for building ASP.NET Core APIs, Blazor apps, EF Core data access, CQRS with MediatR, async patterns, DI, testing, and performance tuning including EF migrations and Result-based error handling.

This skill guides the architectural definition of complex business domains using Domain-Driven Design (DDD). It helps in defining core subdomains, separating services by bounded contexts, and establishing a unified ubiquitous language. It is essential for decomposing monoliths, structuring microservices, and aligning team ownership with clear domain boundaries.

Expert .NET backend architect guidance for C#, ASP.NET Core, Entity Framework, Dapper, caching, testing, and DevOps so teams can build production-grade APIs, microservices, and enterprise applications with clear patterns and performance best practices.

Provides expert .NET/C# backend work for ASP.NET Core 8+ APIs, covering EF Core data access, authentication/authorization, background services, performance tuning, and production-ready patterns for enterprise services.

Provides a workflow for building cloud-ready .NET 8 services, covering minimal APIs, clean architecture layering, EF Core data access, MediatR CQRS, JWT auth, and AOT-ready microservices deployments.

Defines the primary Exa Core Workflow A for implementing the main use case, running core feature integrations, and handling the expected API output, manual steps, and error guidelines.

Executes Fireflies.ai primary Core Workflow A for main features, handling initialization, execution, and finalization while surfacing API results and errors.
