This skill guides you in implementing Command Query Responsibility Segregation (CQRS) patterns for scalable software architectures. It focuses on separating read and write models to optimize query performance and support event-sourced systems. Use this when you need to scale reads independently from writes or handle complex query scenarios. It is suitable for building high-performance reporting systems where detailed read/write data models are required.

Expert data engineer specializing in scalable data pipelines, modern data warehouses, lakehouse architectures, and real-time streaming. Proficient in Apache Spark, dbt, Airflow, Kafka, and cloud-native platforms (AWS, Azure, GCP). Focuses on reliable, performant, and cost-effective data solutions with strong emphasis on data quality and governance.

Expert guidance for designing scalable batch and streaming data pipelines, covering ETL/ELT, orchestration, dbt transformations, data quality, lakehouse storage, monitoring, and cost optimization.

This comprehensive workflow guides the entire database lifecycle, from initial architecture design (covering both SQL and NoSQL) to advanced implementation, optimization, and maintenance. It covers crucial stages like schema design, implementing migrations, optimizing query performance, developing robust data pipelines (using tools like Airflow and dbt), and managing data quality and operations. Ideal for engineers building complex, production-grade data systems.

This skill simulates a cloud cost optimization expert specializing in reducing infrastructure expenses across AWS, Azure, and GCP. It analyzes complex cloud spending patterns, identifies waste, overprovisioning, and potential savings opportunities. It provides actionable recommendations, implements cost controls, and proposes cost-effective, reliable architectures, ensuring cost efficiency without sacrificing performance or reliability.

This skill guides the definition of relationships and integration contracts between distinct bounded contexts within a complex system using Domain-Driven Design (DDD) patterns. It is crucial for preventing domain leakage, planning anti-corruption layers (ACLs), and clarifying ownership boundaries when multiple services interact, ensuring a robust and scalable system architecture.

This skill provides direction and intent for frontend design tasks. It helps define purpose, tone, domain, color world, and review criteria before coding. It incorporates cross-domain lenses from cinema, architecture, marketing, UX, and automotive design to create memorable interfaces. Use it with the design skill to ensure intentional craftsmanship, focusing on constraints, differentiation, and high-impact visual elements while maintaining accessibility and performance standards.

Design and build interactive playgrounds that let developers experience your product without commitment. Covers playground architecture, pre-populated examples, embedding strategies, gating decisions, and converting users to signups.

A comprehensive, end-to-end workflow bundle guiding developers through the entire software development lifecycle. It covers project scaffolding, frontend development (React/Next.js), robust backend architecture, database design, rigorous testing (TDD, E2E), code quality review, and modern CI/CD deployment practices for web and mobile applications.

Generate, refine, validate, and render diagrams from natural language, notes, code, schemas, or existing diagram sources. Supports flowcharts, swimlanes, attack-path graphs, data-flow diagrams, architecture, and state machines using Mermaid, Graphviz, or PlantUML.

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.

This skill creates comprehensive technical documentation from existing codebases. It analyzes architecture, design patterns, and implementation details to produce long-form technical manuals and ebooks. The documentation includes executive summaries, architecture overviews, design decisions, core components, data models, and deployment considerations. It helps onboarding new team members and supports long-term maintenance by providing clear, structured, and accessible technical references in Markdown format.
