Skill UI

Design and implement robust API integrations using expert patterns for REST, GraphQL, and webhooks. Focus on contract-first design, resilience, observability, and security. Includes strategies for authentication, rate limiting, error handling, and debugging to ensure production-ready solutions.

Decision-making guide for API design: choosing REST, GraphQL or tRPC, defining response envelopes, error formats and pagination, planning versioning, authentication, rate limiting and documentation. Includes a heuristic source scanner script.

Implement secure API design patterns including authentication, authorization, input validation, and protection against vulnerabilities. Covers JWT token contracts, refresh sessions, resource authorization, and input parsing. Suitable for backend developers securing endpoints, preventing abuse, and ensuring data integrity in production environments.

This skill provides expert-level review and guidance for complex software systems. It covers modern architecture patterns like microservices, event-driven design, and clean architecture. The architect evaluates scalability, resilience, security, and maintainability. It helps ensure architectural integrity and compliance with best practices across distributed systems and cloud-native environments.

This skill provides expertise in proven backend architectural patterns, including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design (DDD). It guides users in building highly maintainable, testable, and scalable systems. Use it when designing new services, refactoring complex monoliths, establishing team standards, or planning microservice decompositions. It emphasizes defining clear boundaries and handling complex, durable workflows.

Master secure authentication and authorization implementation using industry-standard patterns. Covers user login systems, REST/GraphQL API security, OAuth2, SSO, session management, and RBAC design. Includes guidance on token lifecycle, secrets storage, and threat modeling to protect resource access boundaries effectively.

Design patterns for building autonomous coding agents, including tool calling APIs, permission systems, browser automation, and human-in-the-loop workflows. Inspired by Cline and OpenAI Codex, this skill provides guidance for creating efficient and safe AI agents.

This skill covers AWS development focusing on infrastructure automation and cloud architecture patterns. It provides guidance and best practices for building scalable cloud solutions using AWS services. Suitable for tasks involving infrastructure as code, resource management, and architectural design within the AWS ecosystem.

A comprehensive, multi-phase workflow designed for creating production-ready Bash scripts. This guide covers the entire development lifecycle, including defensive pattern implementation, structured error handling (traps, retry logic), logging strategies, rigorous unit testing using Bats, and professional documentation. Ideal for system administration, CI/CD automation, and core DevOps scripting.

A comprehensive guide detailing the implementation of the 'Bento UI' design pattern across web (CSS Grid), mobile (SwiftUI), and cross-platform (Flutter) environments. This pattern creates highly structured, modular, grid-based dashboards resembling modern app layouts, ensuring aesthetic consistency and responsiveness.

This comprehensive guide provides implementation details for Card-Based Design, a popular pattern for displaying bite-sized, discrete information units. It covers best practices for achieving responsive, Pinterest-style layouts across multiple platforms, including modern CSS Grid/Masonry for web, and native frameworks like SwiftUI, Flutter, and React Native for mobile apps. Use it when structuring content feeds, portfolio grids, or news articles.

This skill covers backend architecture patterns, API design, and database optimization specifically for Node.js, Express, and Next.js. It provides server-side best practices for building scalable applications. Use this for designing robust backend systems and optimizing performance in modern web development environments.
