Skill UI

Covers core principles of 2D game systems, from sprite management and tilemap layering to physics, cameras, and genre patterns, helping developers design clear, responsive 2D gameplay.

Guides designers in creating Claude Code agents by defining frontmatter, triggering conditions, system prompt structure, color/tool choices, and quality best practices for autonomous workflows.

Provides an architectural decision-making framework for analyzing requirements, weighing trade-offs, and documenting ADRs when designing or evolving systems.

Provides experienced architecture guidance for designing scalable distributed systems, documenting decisions with ADRs, evaluating technology trade-offs, and planning infrastructure, diagrams, and reviews for new or existing systems.

This skill provides comprehensive guidance on mastering proven backend architectural patterns, including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design (DDD). It helps users design, refactor, and scale complex systems by defining clear module boundaries, managing dependencies, and ensuring testability. Use it when migrating monolithic applications, initiating microservices decomposition, or establishing robust architectural standards.

This skill is designed to execute complex, structured workflows and actions based on a defined overview. It facilitates systematic process completion and adherence to scope. Users must ensure the task precisely matches the skill's scope, and remember that the output is not a substitute for manual validation or expert review.

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.

Designs and executes chaos experiments, failure-injection frameworks, and game days for distributed systems, providing runbooks, manifests, rollback plans, and continuous resilience automation in CI/CD.

Provides expert guidance on designing scalable, resilient backend systems by defining service boundaries, API contracts, integration patterns, and observability while covering microservices, distributed systems, and event-driven initiatives for production-grade platforms.
