Apply Clean Architecture + DDD + Hexagonal patterns to backend services. Use when designing APIs, microservices, domain models, aggregates, repositories, bounded contexts, or scalable backend structure. Triggers on DDD, Clean Architecture, Hexagonal, ports and adapters, entities, value objects, domain events, CQRS, event sourcing, repository pattern, use cases, onion architecture, outbox pattern, aggregate root, anti-corruption layer. Language-agnostic (Go, Rust, Python, TypeScript, Java, C#).
Pattern for building MCP servers in Next.js with mcp-handler, shared Zod schemas, and reusable server actions.
Build robust backend systems with modern technologies (Node.js, Python, Go, Rust), frameworks (NestJS, FastAPI, Django), databases (PostgreSQL, MongoDB, Redis), APIs (REST, GraphQL, gRPC), authentication (OAuth 2.1, JWT), testing strategies, security best practices (OWASP Top 10), performance optimization, scalability patterns (microservices, caching, sharding), DevOps practices (Docker, Kubernetes, CI/CD), and monitoring. Use when designing APIs, implementing authentication, optimizing database queries, setting up CI/CD pipelines, handling security vulnerabilities, building microservices, or developing production-ready backend systems.
Clerk authentication router. Use when user asks about adding authentication, setting up Clerk, custom sign-in flows, Next.js patterns, organizations, syncing users, or testing. Automatically routes to the specific skill based on their task.
Use when implementing features across frontend and backend, building APIs with UI, or creating end-to-end data flows. Invoke for feature implementation, API development, UI building, cross-stack work.
Use when structuring or refactoring Convex codebases with Domain-Driven Design boundaries, repository abstractions, adapters for external APIs, and transaction-safe workflows.
Java coding standards for Spring Boot services: naming, immutability, Optional usage, streams, exceptions, generics, and project layout.
Develop applications using the Docyrus API with @docyrus/api-client and @docyrus/signin libraries. Use when building apps that authenticate with Docyrus OAuth2 (PKCE, iframe, client credentials, device code), make REST API calls to Docyrus data source endpoints, or construct query payloads with filters, aggregations, formulas, pivots, and child queries. Triggers on tasks involving Docyrus API integration, @docyrus/api-client usage, @docyrus/signin authentication, data source query building, or Docyrus REST endpoint consumption.
Implement Syncfusion ASP.NET Core Gantt Chart component (EJ2) for project management and task scheduling. Use this when working with Gantt charts, project timelines, task dependencies, or resource allocation in ASP.NET Core applications (Tag Helper/Razor Pages/MVC). This skill covers data binding, task management, editing, filtering, export, and timeline customization.
Manage NuGet packages in .NET projects/solutions. Use this skill when adding, removing, or updating NuGet package versions. It enforces using `dotnet` CLI for package management and provides strict procedures for direct file edits only when updating versions.
Amazon DynamoDB patterns using AWS SDK for Java 2.x. Use when creating, querying, scanning, or performing CRUD operations on DynamoDB tables, working with indexes, batch operations, transactions, or integrating with Spring Boot applications.
MySQL development best practices for schema design, query optimization, and database administration
