Skill UI

Guides REST and GraphQL API architects through domain modeling, OpenAPI 3.1 contract drafting, pagination, versioning, error handling, and mock verification.

A comprehensive, production-grade reference architecture for integrating with Apollo.io. It details a layered design encompassing API services, business logic, background job processing (e.g., lead enrichment), and data modeling, enabling the building of robust sales intelligence and CRM synchronization systems.

Automates guidance for Attack Surface Analyzer within the Security Advanced domain, offering best practices, code snippets, and validation to help with penetration testing, compliance, and threat modeling workflows.

Automates guidance for Attack Surface Analyzer within the Security Advanced domain, offering best practices, code snippets, and validation to help with penetration testing, compliance, and threat modeling workflows.

Provides canonical AWS serverless patterns covering Lambda handlers, DynamoDB single-table modeling, CDK infrastructure, and S3 event processing along with anti-patterns and a checklist for production-ready deployments.

Automates cloud security posture assistance within the Security Advanced domain, guiding practitioners through best practices, compliance checks, threat modeling, and prod-ready configurations whenever they mention cloud security posture.

Assists container security auditors within the Security Advanced domain by auto-activating when key terms appear, walking through best-practice guidance, producing production-ready code/configurations, and validating results against compliance and threat-modeling standards.

A comprehensive, expert-level skill for designing, analyzing, and optimizing robust database schemas. It covers normalization, index tuning, choosing between SQL/NoSQL, and implementing zero-downtime data migrations. Provides systematic workflows for schema analysis, performance modeling, and advanced SQL pattern generation.

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.

This skill guides the application of Domain-Driven Design (DDD) tactical patterns, including defining aggregates, modeling value objects, managing repositories, and utilizing domain events. It helps developers translate complex domain rules into clean, robust, and behavior-rich code structures, ensuring invariants are explicitly enforced.

This skill guides the planning and execution of complex business domains using Domain-Driven Design (DDD) principles. It helps developers move from strategic modeling (defining subdomains and bounded contexts) to tactical implementation patterns like CQRS, Event Sourcing, and Saga orchestration. Use it when dealing with complex, high-variability business rules and needing explicit architectural boundaries.

This comprehensive skill covers the full scope of Firebase services, including Authentication, Firestore, Cloud Functions, and Hosting. It goes beyond basic implementation, focusing on critical architectural principles: adopting a query-first, denormalized NoSQL mindset. Key insights include mandatory security rule design, optimal data modeling for performance, and correctly utilizing modular SDKs to build scalable and secure backends.
