Skill UI

This skill covers critical PowerShell Windows patterns including operator syntax rules, null checks, error handling, and file path management. It emphasizes avoiding common pitfalls like missing parentheses, Unicode characters, and type mismatches to ensure robust script execution.

This skill provides language-specific super-code guidelines for Python, covering idioms, efficiency, and best practices. It includes recommendations on comprehensions, unpacking, built-ins, functions, classes, error handling, type hints, and common anti-patterns to improve code quality and readability.

An end-to-end workflow for building robust, production-ready Python backend APIs. This guide covers all stages, including project scaffolding, SQLAlchemy database integration, Pydantic validation, implementing JWT/OAuth2 authentication, comprehensive error handling, unit testing, and Docker deployment for modern microservices.

Modern React UI patterns for loading states, error handling, and data fetching. Use when building UI components, handling async data, or managing UI states to ensure optimal user experience and application stability.

A skill providing language-specific super-code guidelines for Ruby, covering enumerable collections, blocks, string handling, error handling, classes/modules, idioms, and anti-patterns. Ideal for developers writing idiomatic, efficient Ruby code.

This skill provides comprehensive guidelines for writing idiomatic and efficient Rust code. It covers key topics such as ownership, borrowing, error handling, iterators, pattern matching, structs, enums, and concurrency. It helps developers avoid common anti-patterns and adopt best practices for production-ready Rust applications.

This skill provides comprehensive, production-grade patterns for asynchronous programming in Rust using the Tokio runtime. It covers essential concepts like tasks, channels, and streams, along with robust error handling techniques. Use it when developing concurrent network services, building complex async applications, or optimizing performance in Rust.

Master Rust 1.75+ with advanced async patterns, type system features, and production-ready systems programming. Covers ownership, concurrency, web services, error handling, testing, unsafe code, and modern tooling.

This skill provides comprehensive guidelines for writing idiomatic and efficient Swift code. It covers best practices for optionals, collections, value types, error handling, concurrency, and protocol-oriented design to improve code quality and maintainability.

Guides the TDD red phase by generating comprehensive failing tests that define expected behavior, edge cases, and error handling across multiple frameworks (Jest, pytest, JUnit, Go, RSpec). Ensures failures are meaningful and test isolation.

Master Temporal workflow orchestration using the Python SDK. Covers durable workflows, saga patterns, and distributed transactions. Includes guidance on async/await execution models, worker configuration, activity implementation, error handling, retry policies, and production deployment strategies. Ideal for building reliable, scalable distributed systems with long-running processes and deterministic coding practices.

This skill generates appropriate user feedback states for components and pages, including loading skeletons, empty states, error messages, and success toasts. It ensures consistent UI presentation by implementing specific design patterns for data-dependent areas, handling partial or full failures, and providing retry mechanisms. It follows design language references for animations and accessibility, suitable for React-based frontend development workflows.
