This skill provides expertise in writing strict POSIX-compliant shell scripts for maximum portability across Unix-like systems. It focuses on shell-agnostic scripting compatible with dash, ash, sh, and bash in POSIX mode. Key areas include defensive programming, portable error handling, safe argument parsing, and cross-platform compatibility. It ensures scripts run on Linux, BSD, Solaris, AIX, and macOS without relying on GNU-specific features or bash extensions.

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 focuses on designing Software Development Kits (SDKs) that developers enjoy using. It emphasizes creating APIs that feel native, providing helpful error messages, and reducing friction in the development process. The goal is to drive adoption through exceptional developer experience rather than aggressive marketing strategies.

A comprehensive automation toolkit for managing Sentry error tracking and monitoring operations. Users can programmatically investigate issues, configure project-level alert rules, manage release versions, and monitor organizational structure. Essential for DevOps and development teams needing deep integration and programmatic control over error data.

This skill provides comprehensive guidance on implementing observability patterns for service mesh deployments like Istio and Linkerd. It covers metrics, tracing, logging, and dashboard configuration using Prometheus, Grafana, and Jaeger to monitor latency, errors, and traffic effectively.
